The Race: GG VII Potpourri and the World’s Largest Reptile

Much has happened since my last post from the islands a couple of months ago which accounts for the tardiness of this one. However, Rayna Bell, our Cornell PhD candidate did manage to post two videos via National Geographic while we were on the islands.

I was invited to speak in TEDxSão Tomé, a great honor, and so returned in mid-June.  Readers should know that there is but one TAP flight to the islands per week via Lisbon so this is no small undertaking especially for a single lecture.  TEDx was a wonderful experience, and I was able to meet with some the brightest young people from the islands and to “spread the biodiversity word” internationally as well.

In the meantime, back at the Academy, we have been assessing the results of our fieldwork on GG VII; below is an image of the 2013 team, along with some of our best local friends.

The tall Sao Tomean in the back row, and the woman on the far right are Quintino Quade and Roberta dos Santos, respectively; the gentleman in the wheelchair is Ned Seligman. All three work for an NGO called STeP UP which has interacted closely with our CAS teams since the very beginning, especially with our biodiversity education efforts.

Shortly after returning, I learned from two colleagues here at CAS, entomologists Dr. Paco Hita Garcia and Georg Fischer, that they had described a new ant species from Sao Tome back in 2010, but somehow forgotten to tell me! The members of GG I collected these along the trail from Bom Successo and Lagoa Amelia  over 12 years ago!

Miko Nadel, our lichenologist, has narrowed the focus of his MA dissertation to the fruticose lichens of the genus Usnea which are found at higher elevations on the islands. He ascended Pico Príncipe, and readers will recall that he was part of the team that ascended Pico do São Tomé during GG VI.  He now has over 600 collections upon which to base the first survey of this group in the islands.

Miko’s major advisor at San Francisco State University is Dr. Dennis Desjardin, a world authority on mushrooms and veteran of GG II and III. The blog of a year ago (April: Mountains that Glow) featured Miko’s discovery of tiny glowing mushrooms on Pico Sao Tome and later, glowing mycelium (threadlike plant body of fungi) covering steep hillsides at around 1100 meters. This year our photographer, Andrew Stanbridge, returned to Macambrara, the second locality, and discovered larger whole mushrooms that glow, not just the vegetative bodies. The two images below are of the same unidentified mushrooms in daylight and at night.

Rayna Bell reports from Cornell: we have very strong evidence now that the two species [São Tomé giant treefrog and Oceanic treefrog] are hybridizing [on São Tomé] (individuals of intermediate size/color and lots of molecular data to back that up), and now the question is whether they have always exchanged migrants and still diverged in body size, coloration, and breeding site (divergence with geneflow) or if they were isolated in the past and have recently come back in to contact (allopatric speciation). Just as exciting is that Rayna has discovered that the Oceanic tree frog, Hyperolius molleri (right below), that has long been thought to occur on both islands, does not; i.e., although very similar to each other morphologically, the two island populations are very different genetically, contradicting earlier molecular work by one of my interns years ago! Rayna and one of her undergraduate students just published their GG VI findings of chytrid fungus on the Sao Tome Cobra bobo; this is only the second published incidence of the fungus on a caecilian species.

Dr. Tamas Szuts, our Hungarian spider expert, was able to make great collections of salticids (jumping spiders) and orb weavers (Araneidae). Tamas was particularly excited about his collections of the genus Pochyta (below), a problematic group within the family.

Many of Tamas’s specimens are still being identified, but he writes: I also made some interesting observations about their [Pochyta] life history: a specimen had camped on a leaf just above a Phallus muchroom which attracted some small flies. [The] specimen was observed to jump several times toward the flying or landing targets, and then climbing back onto the leaf with the aid of its dragline.
Tamas took the remarkable photos below.

Finally, since we returned in May I have received several remarkable photographs of leatherback sea turtles, Dermochelys coriacea, one of four species that nest on the beaches of São Tomé and Príncipe. In terms of mass, this is the largest reptile in the world. The largest female on record was 915 kg (just under 1 ton, and close to 3 meters long (9.8 feet)!

The Race: Principe Island–A New World Biosphere Reserve!!

During GG VII, just completed, a rather remarkable thing happened which readers should know about. I will write a wrap-up of Gulf of Guinea VII next month, but in the meantime I want to talk about Príncipe Island in general and what has just happened there.

Readers will already know that this blog is about our 13 years of biodiversity work in the Republic of São Tomé and Príncipe. The latter island is about twice as old as the former, at 31 million years. It is much, much smaller, but when it first arose volcanically from the ocean floor it was nearly four times the current combined area of both islands today.

Latest working GofG
RCD construct, Google Earth.

Príncipe’s great age is responsible for its remarkable appearance, a landscape punctuated by ancient steep volcanic plugs and a mesa, mostly made up of a rather rare rock known as phonolite.

Isolated for so many millions of years, it also harbors a large number of unique plants and animals we call endemics; organisms that have arrived on the islands by random dispersal, established colonizing populations that have accumulated genetic change over deep time, so that they are no longer the same as their ancestors on the mainland.  An endemic species is one that is found only in one place, nowhere else.

P endemics

All of the species above are unique to Príncipe Island and nowhere else in the world.  There are many more not pictured, but fewer than on São Tomé because that island is much larger, thus more niches. Virtually every one of our expeditions has turned up new, undescribed species from both islands as they remain incompletely known. Our work on these islands has been ongoing for 13 years and has included over 40 scientists of different disciplines and their graduate students.
A year or so, I was contacted by scientists from Madeira to provide information in support of an application to have Príncipe Island established as a World Biosphere Reserve by UNESCO.
UNESCO defines World Biosphere Reserves thus:
Biosphere reserves are sites established by countries and recognized under UNESCO’s Man and the Biosphere (MAB) Programme to promote sustainable development based on local community efforts and sound science. As places that seek to reconcile conservation of biological and cultural diversity and economic and social development through partnerships between people and nature, they are ideal to test and demonstrate innovative approaches to sustainable development from local to international scales.
Biosphere reserves are thus globally considered as:
•    sites of excellence where new and optimal practices to manage nature and human activities are tested and demonstrated;
•    tools to help countries implement the results of the World Summit on Sustainable Development and, in particular, the Convention on Biological Diversity and its Ecosystem Approach;
•    learning sites for the UN Decade on Education for Sustainable Development.
I was delighted to supply supportive lists of floral and faunal species and photographs to illustrate the uniqueness of Príncipe, as this would be a wonderful opportunity  for this tiny island with fewer than 5,000 inhabitants.  Although I never received a copy of the completed application, I learned some months ago that the application had been successful, and that Príncipe Island had indeed become a new  World Biosphere Reserve!!
What I did not anticipate was that I and my team would be on the island at the same time as the formal presentation. We were invited to the ceremony,  Saturday the 4th of May, by Regional President Jose Cardosa Cassandra himself during our annual meeting, and at the same time he asked if I would serve on his Scientific Advisory Council, a great honor and responsibility.

Later, during his speech, President Cassandra acknowledged both me and the California Academy of Sciences by name, as having provided much of the biological ground work for the successful application.  He asked that I stand and be recognized… it was a unique moment, and even more so when the Prime Minister did the same in the next speech! V. Schnoll phot

IMG_3119
After the formal presentation which included around 250 people, there was a series of panel discussions, in which we took part. The rather odd configuration of Velma Schnoll’s photo above is because President Cassandra insisted that Roberta Ayres (our senior educator on the CAS team) translate for me. Roberta is short, I am tall.

Finally Velma took a group picture. This includes the REDBIOS committee that originally submitted the Biosphere application; on the left is our old friend Arlindo Carvalho, Director General of the Environment He authorizes our research on the islands. Just to the left of the certificate is Regional President Jose Cassandra, and please note that he has put one of our CAS expedition patches on his shirt! To the right of the certificate is the UNESCO representative, and to my right is Dr. Antonio Abreu, whose people first contacted us for the biological information for the application.  Phot. V Schnoll, GG VII

To say that this was a great and joyful day would be an understatement.  We know that our science is importance, and we can see that our Biodiversity Education project is making a difference tremendous with the kids.  But to have contributed to an event of global magnitude for this wonderful island country makes me and I am sure all who have joined me on these many Gulf of Guinea Expeditions very proud.

The next blog will be a summary of what we think we accomplished on GG VII.

The Race: GG VII—We Reunite and Part Again

After two hectic weeks of education activities on São Tomé, Rayna Bell (Cornell University) arrived and the four of us joined the botanists, Tom Daniel, Jim Shevock, Miko Nadel, Tamas Szuts (our spider guy) and Andrew Stanbridge (our photographer) on Príncipe.   I  have asked Andrew, a veteran of three Gulf of Guinea expeditions, to illustrate some of what transpired while the group was divided.

The Race: GG VII – – First Week: Snakes, Workshops and Spiders

Our first week is now complete. The botanists and Andrew our photographer went to Príncipe early so I will include their progress in a later blog. One thing I will add though is a picture Andrew emailed us yesterday, a shot of the endemic diurnal green snake, the Príncipe Soá-soá. We have only been able to collect one of these (GG I); it is an extremely elusive species.

Saturday we held our first ever teacher workshop at Escola Primaria Maria de Jesus, the largest primary school in the country (2,000+ kids).

IMG_2293RCD phot GG VII

 We spoke to 58 teachers about island biodiversity in more depth so that they can use the materials we have brought more efficiently. The hour and a half presentation was extremely well received, even though we had to project our powerpoint on the back of a canvas painting!

The Race: “Raising Awareness”- Gulf of Guinea Expedition VII (II. The Educators)

Our first contingent of six participants is leaving for São Tomé and Príncipe in about a week, with three additional joining us a week or two later.  As preparations continue, I want to reiterate the educational part of our on-going mission.  Readers will already know that big changes are coming to these two ancient and fascinating islands, mostly due to the discovery of oil within their Exclusive Economic Zone.  At the same time, the inhabitants of the island, a little less than 200,000 in number, are largely unaware of how biologically unique their islands are (as is much of the world, hence this blog and our 20+ scientific publications).  During GG IV, 2010, we assessed the level of biodiversity training in the local schools and decided to embark on a biodiversity education campaign.
Obviously, our small group cannot do this alone, nor should we, and so in describing our efforts so far, I must include some of the amazing citizens who have been and remain essential to our success.
Three of our most important local educators (and close friends) are Roberta dos Santos, Quintino Cabral Quade and Ned Seligman.

I have known Ned since childhood in San Francisco, and it was at his urging that I first visited the islands in 2000.  He introduced me to Roberta and Quintino both of whom worked for his NGO at the time. Quintino took us all over the island and I was hooked.

Ned has had more than 25 years experience working with grassroots development organizations in Africa and was the Peace Corps Director in São Tomé and Príncipe for 3 years in the mid 1990’s. Before setting up STeP UP, a local development NGO on São Tomé, he worked for the World Wildlife Fund, World Learning, Catholic Relief Services, the American Friends Service Committee and the PeaceCorps. He received his B.A. from Yale University and a Masters Degree from Johns Hopkins University Ned is the founder and Director of STeP UP with which our educational work is closely associated. Ned’s house on Praia Francesa is our unofficial “home away from home.” His lunch salads are legendary!

Roberta dos Santos (left) and me at primary school in São Tomé.  A. Stanbridge phot. GGVI

Roberta dos Santos is a member of a very old São Tomé family.  As a young girl, she was selected as a member of a group of São Tomeans to travel to the US to learn to teach English as a foreign language.  Roberta has worked with community-based organizations in São Tomé since 1990, when she started working for the Peace Corps as Assistant Director. Prior to the Peace Corps, she taught English for twenty years in São Tomé’s only high school and later at the Diocesan Institute Joao Paulo II. She received advanced training in TEFL for three years in Buffalo, NY. Having been born and raised on the hot tropical island of São Tomé, Roberta’s description of landing for the first time in Buffalo, New York in February, the dead of winter, is truly hysterical.  She is well known in the educational community, has helped us plan our school visits and vetted our educational materials.  She and Quintino usually join our school visits as translators.

Quintino Quade graduated from the Teacher Training Institute “Tchico Te” in 1993 and was a teacher, first in a middle school and later in a high school in Bissau, the capital of Guinea-Bissau. During the war in that country, he emigrated to São Tomé and has been working with STeP UP since 1999.

One of our strongest supporters and wisest counselors is Henrique Pinto da Costa.  Henrique is a former Minister of Agriculture and has always been interested in youth development; we discuss most of our education ideas with him.  He is the brother of the current President of the Republic, Manuel Pinto da Costa. We actually captured an endemic spider in his garden (see Sept 2, 2011 blog).

The Biodiversity Activity cards, our educational tools for GG VII

During GG VI, we visited 40schools, 67 classrooms and distributed 1823 coloring books to third graders.  In GG VII, beginning in April, our education team intends to visit the same classes in the same schools on both islands, only now the children will be fourth graders. Our educators, Velma Schnoll and Roberta Ayers have developed a series of games for the students to play at the same time increasing their awareness of the unique fauna and flora of both islands.

The Race: Two More New Species for São Tomé and Príncipe

Just as I was preparing to write more on the up-coming GG VII,  I received some great news. Long-time readers will recall that Gulf of Guinea III (B) in 2008 was a marine expedition that included a graduate student named Dana-Carrison Stone (see “Send in the Marines” and several subsequent blogs). Dana completed her MSC thesis a year or so ago, and has just published part of her dissertation that includes the description of two new species of barnacles. The publication is in ZooKeys 270.

The Race: Endemicity and the Gulf of Guinea VII Expedition (I. The Scientists)

Readers may recall that last March, prior to GG VI, I gave several lectures in Portugal on Gulf of Guinea island biodiversity. The last was an international colloquium on São Tomé and Príncipe held at the University in Lisbon. There I met a number of the participants, among whom were old friends and a delightful entomologist named Dr. Luis Mendes; Luis and I remained in contact, and he has just published and sent me the most up-to date survey of the butterfly fauna of the islands butterfly fauna.

BUTTERFLIES

As we have learned to expect, the endemicity (uniqueness) level is high. Luis and his colleague, Bivar de Sousa, report 111 species present on both islands, 29 of which are found nowhere else in the world. Thus, fully a quarter of the butterflies (26%) are endemics. This is further testimony to the great age of these islands, as we know that genetic change (evolution) occurs with isolation and time. Last month, another paper appeared by Loureiro and Pontes confirming the endemic status of a species of dragonfly, Trithemis nigra found only on Príncipe but not seen for many years.

The image below is a summation of our current knowledge of  some of the insect endemicity on the two islands; much of the data upon which this summation is based are very old, and so much more work needs to be done.

We are getting ready for GG VII (April-May), and below is our new logo for the expedition; note that the famous Cobra bobo, a legless amphibian found only on São Tomé has been joined by an endemic Príncipe snake, also called Cobra bobo but entirely unrelated. (The cartoons of both animals were made by my graduate student, Dashiell Harwood, and the layout was by a member of our Biodiversity Education Team, Michael Murakami.

Jim Shevock, a world-class bryologist, will be joining us for the third time. As you can see from the data above, he has already greatly increased our knowledge of mosses and their relatives on the islands, and there are still many species to be found. For example, during GG VI last year, Jim returned to the same locality along the Rio Papagaio in Príncipe that he had collected during GG V; in GG VI and found many plants he did not find the first time, including 10 of them new to the country! Jim has worked a lot in Asia and his nickname on Taiwan is “Little Bear.”

During GG VI she studied possible hybridization between the two endemic São Tomé treefrog species Hyperolius thomensis and H. molleri and currently has a paper in press on her work with us last year. This year we will try to find the elusive tadpole (larva) of the Príncipe giant treefrog which remains undescribed. Leptopelis palmatus is the largest treefrog in Africa.  Speaking of herpetology, to date our CAS island specimens and tissues have been used in 33 scientific publications, internationally!

The Race: Peregrinations of a Pinniped (Our Islands get Seal of Approval)

I have recently learned from my island friend Madalena Patacho of Bom Bom Island that a Cape fur seal (Arctocephalus pusillus) was seen and photographed on a beach at the north end of Príncipe Island and was also later seen by a number of islanders along the São Tomé coast.

 

The Cape (South African) fur seal, Arctocephalus pusillus at Praia Sundy, Principe Id. December 2012. photo by Jamili

Why is this noteworthy? It is special because although vagrant individuals of this large species have occasionally been seen as far north as the southern border of Angola, the nearest breeding colony of Cape (or South African) fur seals is just under 2,700 km south of Príncipe, at Cape Cross Namibia!  This is almost exactly the same distance as between Príncipe and Kampala, Uganda.

My colleague, Bastien Loloum works for MARAPA, an NGO on the islands heavily involved in marine life and conservation. Bastien is coordinator of a cetacean  monitoring program there. So far they have recorded ten species of cetaceans but he informs me that there are no formal records of the Cape fur seal in the islands waters.  However, he and his colleagues think that this is may be the second or third account of a vagrant fur seal there during the past decade.  This would be rare indeed, but for reasons given below, I am not too surprised.

Map from  IUCN Red list.

The Cape or South African fur seal is the largest of its kind (Otariidae= fur seals + sea lions; true seals lack external ears and belong to a different family, the Phocidae); males reach 2.27m in body length and 360kg in mass. Females are much smaller. As the map shows, this species lives and breeds along the South African and Namibian coast. There are about 23 major breeding colonies, and there are population estimates of over one million individuals. In 1992,  I was fortunate to explore the Skeleton Coast of Namibia by air from Capetown to about 16º south latitude, and the Cape fur seal colonies were impressive to say the least.

Above the Namib coast;  RCD photo 1992

Above the Namib coast;  RCD photo 1992

Later and somewhat farther north, we were able to approach a colony by land as there were intervening rocks disguising our presence.

On the Namib Coast.  RCD phot. 1992

Note the conspicuous external ear which is one characteristic that differentiates these mammals from true seals. RCD phot. 1992

The key to understanding how these enormous populations of large pinnipeds are sustained, and how one individual might have arrived in the Gulf of Guinea 2700 km to the north lies in understanding the nature of the Benguela Current which flows up the west coast of southern Africa. The Benguela is a cold current and is thus highly oxygenated water. This supports vast amounts of plankton which in turn provide sustenance for a huge marine fauna “higher up the chain.” In fact, the Benguela Current is one of the richest fisheries in the world.

Notice the persistent, thick, slightly discolored foam on the shore which indicates high plankton content in the water. RCD phot. 1992

A major factor important to our seal story and indeed, perhaps to the early colonization of the Gulf of Guinea islands’ unique plants and animals, is the fact that the Benguela Current flows from South to North and has undoubtedly done so since the Atlantic Ocean opened up in the Cretaceous.

Dominant currents in  the Gulf of Guinea and South Africa.  CAS construct

As the map shows, the Benguela flows north past the Congo River Delta. At the same time, the Guinea Current flows West to East across the Niger Delta. These two currents converge in the Bight of Benin to form the South Equatorial Current, and this major current flows due West, directly through the Gulf of Guinea Islands and across the Atlantic.

Hypothesized raft. artwork by Richard E. Cook. insert photos D. Lin GG I and II

Because these two major currents cross the deltas of two of the mightiest rivers in Africa each with huge interior drainages, then change direction westward through São Tomé and Príncipe suggested to us that many of the endemic plants and animals on the two islands arrived there millions of years ago by rafting.  We suggested that the raft(s) would be large chunks of riverbank which broke off and floated to the sea. Our hypothesis that the rafts would have been very large is supported by the fact that a significant percentage of the unique reptiles (and one amphibian) of both islands are burrowing species (see inset, above), unlikely to cross ocean barriers on small floating objects.  We published this hypothesis in the Journal of Biogeography in 2007.

With respect to our Cape fur seal visitor, a closer look at the first image reveals that this animal ran afoul of a fishing operation of some sort; note the blue polyethylene rope or netting around its neck which may have come from a trawling operation to the south.  While it is highly unlikely that the poor creature was dragged 2700km, it IS possible that having been entangled, and then escaping, the seal became disoriented and probably very much weakened.  It seems likely that the “line of least resistance” would be to follow the Benguela Current until it converged with the South Equatorial Current, ultimately depositing the animal in the waters off São Tomé and Príncipe. This, in a sense, would be following part of the same dispersal pathway as the original plant and animal colonizers of the islands if our rafting hypothesis is correct.  It is impossible to know for sure, but this seems to me a possible scenario.

Here’s the parting shot:

The Race: Flatworms, a New Doctor and an Island Education Video

One of our most consistent and knowledgeable colleagues on the island of São Tomé has been Ricardo Lima, up until recently a graduate student at the University of Lancaster.

Ricardo has been studying the effects of land use changes on the distribution of the endemic birds of São Tomé, and I am delighted that (1) he has just completed his PhD, (2) he has published a fine article on his research in the journal Diversity and Distribution, and (3) he is back on the big island having found funding for the continuation his research. This funding will also allow the reprinting of the biodiversity posters we distributed during GG V in 2011.Readers will recall we were able produce only 200 of these (see March – April 2011 posts).

ricardo-good

Dr. Ricardo Faustino de Lima being savaged by a Sao Tome malachite kingfisher (unknown phot)

Over the several years I have known him, Ricardo has sent us images and/or specimens of great interest to us both, including a freshwater fish we missed in our 2001 and 2006 river surveys (we still have not analyzed one), and especially the specimens of the endemic shrew, Crocidura thomensis which we subsequently studied genetically.Dr. Lima will be one of the authors when the shrew paper is completed.A year or so ago, Ricardo sent us some pictures of a strange, brightly colored flatworm called a terrestrial planarian or geoplanid.

plan-in-hand

Terrestrial planarian (geoplanid) (R. Lima phot.]

As delicate as these little terrestrial creatures appear, they are actually voracious predators upon snails, slugs, insects and earthworms.The known species have very narrow, specific habitat preferences and thus can be used as indicators of habitat types. Readers will recall that over 60% of the snails of São Tomé and Príncipe are found nowhere else in the world, including an endemic genus, Bocageia; if this geoplanid is an invasive, it may well be a real threat to the populations of endemic snails.

Terrestrial planarian (geoplanid) (R. Rocha phot.)

Even with a better image in hand (above) we could not put a name on this animal. We have many experts here at CAS, but none specializes in this class of invertebrates, the Platyhelminthes.During GG VI last April, Miko Nadel, our lichenologist graduate student collected a specimen way up at 1700 meters on Pico do São Tomé (see Mountains that Glow, April 2012) and brought it back.

miko-and-jim-as

Miko Nadel (l) and Jim Shevock on Sao Tome [A. Stanbridge phot. GG VI]

Now with a specimen in hand, we needed to find an expert.Thanks to Dr. Shannon Bennett, Head of our Department of Microbiologist, we discovered Dr. Ronald Sluys, of the Netherlands Centre for Biodiversity Naturalis. Dr. Sluys has been sent the specimen and is “willing to give it a try!”.Apparently, there are not all that many experts in this field, and Ron says he will have to section our one specimen with a microtome in order to try to identify it.If it is new, we will try to get more for him; if it has a name, we can add yet another species to the remarkable biota of the islands.

Finally, our readers will know that since GG IV in 2010 we have been developing a biodiversity education program for the youth on both islands.Our volunteer group has put together a video describing the bio-ed project; this will be the first time I have tried to post a video on this blog.It is about 7 minutes long, and if it works, my thanks to Jim Boyer for his expertise.

The Race: Island Biologists in Training

Jens Vindum, Senior Collections Manager, Department of Herpetology. (phot D. Lin-GG I)

I need to add and addendum to last month’s blog, “Why We collect Specimens.” Our Senior Collections Manager, Jens Vindum (GG I, GG II) has just informed me that since 2003, there have been 33 international scientific papers published on our Gulf of Guinea reptile and amphibian specimens and/or tissue samples from them!

Clearly, the scientific world is beginning to hear about Sâo Tomé and Príncipe! At this point, I do not know how much of our material from other disciplines has been used but certainly our samples are in labs all over the world.

We have been extremely fortunate to have been able to bring a series of our graduate students with us on a number of our expeditions.  Not only have most flourished academically and many have published on their island projects, they represent a cadre of new young scientists who have an understanding of the uniqueness of the islands and the people who live on them.  All have interacted closely with local island citizens and as a result, function as young biology ambassadors for these fabulous islands.  Overall, the islands are still very poorly known to the outside world, but we are getting there!  Here are our young colleagues:


Lindsay Wilson on Bioko Island with bush viper.  RCD phot – 1998

Lindsay Wilson was a participant on our 1998 expedition to Bioko, the first island in the Gulf of Guinea chain. She completed her MSc on African treefrogs of the genus Hyperolius at San Francisco State University with highest honors.


Joel Ledford on Sao Tome.  D. Lin phot- GG I

Joel Ledford joined Gulf of Guinea I as the graduate student of Dr. Charles Griswold. He completed his MSc at San Francisco State and then his PhD in spider systematics at the University of California, Berkeley.


D. Lin phot – GG I

Also on GG I was Ricka Stoelting, my graduate student. She completed her MSC on the endemic caecilian of Sao Tome (she is holding one, above) and is currently a PhD candidate at the University of Wisconsin.  She is also working on the publication of her MSc work at San Francisco State (SFSU).


B. Van Syoc photo – GG III

Dana Carrison-Stone was a participant of the marine expedition, GG III as the graduate student of Dr. Bob Van Syoc.  Dana discovered two new species of barnacles from the islands and they are part of her MSc which she completed last year at SFSU.


D. Lin phot – GG II

Josef Uyeda was on GG II and again GG on III as an undergraduate at Willamette University and one of my Summer Systematics interns.  During his island work, he discovered and described a new species of frog from Sâo Tomé. As I write, he is defending his doctoral thesis (tomorrow!) at Oregon State University. Flash!! Josef finished his PhD today! (Oct 5)

Mac Campbell, also a Willamette undergrad, joined GG II as an assistant to our ichthyologist, Dr. Tomio Iwamoto.  He has since completed his MSc at University of Alaska, Fairbanks and is currently a PhD candidate in fish systematic at the same institution.


Weckerphoto – GG III

Rebecca Wenk joined GG III as the grad student of Dr. Tom Daniel one of our senior botanists.  Rebecca’s work resulted in her successful completion of her MSc at SFSU and also an excellent scientific publication on plants of the family Acanthaceae.  Tragically, Rebecca died of a serious illness last year.


A. Stanbridge phot – GG IV

Miko Nadel is a graduate student at San Francisco State, studying under Dr. Dennis Desjardin, the mycologist on GG II and GG III). Miko was a participant on GG VI doing the first comprehensive survey of lichens on the island.

A. Stanbridge phot. GG VI

Rayna Bell also joined us on GG VI, studying color variation in African treefrogs. Rayna is a PhD candidate at Cornell University.

The people above were or still are graduate students who have actually worked on the islands with us.  But they are not the only young academics studying our Gulf of Guinea Island material.  Here at the California Academy of Sciences we have a program known as the Summer Systematics Institute (SSI). This program is funded by the National Science Foundation, and undergraduate students can apply to work on scientific projects for the summer under the mentorship of a CAS faculty member. Here are those that have worked on Gulf of Guinea specimens. I have not included students who started as undergrad SSI interns and later became our grad students (Lindsay Wilson, Josef Uyeda and Ricka Stoelting).


unknown phot

Katie Marshall was an Occidental College undergrad and my SSI intern in 2006.  Katie studied the genetics of the Oceanic treefrog, Hyperolius molleri, the only Gulf of Guinea endemic frog that occurs on both islands.  Katie is currently a PhD candidate at the University of Washington, studying the genomics of marine bacteria.

RCD phot.

Lisette Arellano was an undergrad at the University of California, Santa Barbara when she joined us as my SSI intern in 2009. Lisette examined the morphology and genetics of cobra jita snakes (Lamprophis), long thought to be the same species on Sâo Tomé and Príncipe.  Lisette showed that in fact the two island populations are genetically quite different, also recognizable by color pattern as distinct.  Although we know each island is a different species, we have been unable to publish new names because the relationships of the same group on mainland Africa are still very unclear. Lisette is currently a PhD candidate in Biology at the University of Colorado.


RCD phot – 2010

One of the last vertebrates one would predict to be native to an oceanic island is a shrew, largely due to physiological constraints. During the SSI summer of 2010, Eden Maloney’s DNA work showed that the Sâo Tomé shrew, Crocidura thomensis, did arrive on the island naturally, probably many thousands of years ago and is a true endemic species. Its nearest relative is a different species found in eastern South Africa.  Eden has just graduated from the University of California, Los Angeles and is applying to graduate schools.  We are working on publishing her work.

unkown phot.

Lizzie Miller of the University of California, San Diego was my most recent SSI intern (2010). Lizzie has graduated and is now in graduate school at UCSD studying fish systematics.  Readers will already know from this blog that Lizzie discovered and described a new species of gecko from Príncipe, Hemidactylus principensis.

Lauren in Nigeria. D Blackburn phot – 2012.

Lauren Scheinberg is also a grad student at San Francisco State University. Although never an SSI intern nor has she been with us to the islands, she was my lab assistant on a long-term physiology project and now works as a curatorial assistant in our department.  She has become involved in a rather complicated taxonomic problem with the island skinks of the genus Afroablepharis. Like Lisette’s snakes, we know from the work of colleagues in Madeira and Portugal that the skinks are different species on Sâo Tomé and Príncipe.  Unfortunately, material we loaned them that formed part of the basis of this hypothesis was somehow lost in transit.  Lauren has analyzed our remaining material but collating the information generated by different labs can be extremely difficult.  But we are working on it.

Plans are already afoot for GG VII next year.

Here’s the parting shot:
