“Today was Monday the 16th – we began early in Neves dropping into the schools (3rd grade classes) There were around 285 students today in classes that ranged from 18 – 42 students per. We travelled down some roads that you would not recognize as such to places that are old, crumbling, and surprisingly populated. It was more amazing than I can say to be bringing our coloring books to this place and teaching the kids (and their teachers) about their islands. If you could have seen their faces! You will, when we get the pictures uploaded… I’m too exhausted to write more, but will try to get to posting some pics tomorrow if I have time, but we begin at 6:30 am at the main primary school in Sao Tome. 525 students (only 3rd grade) – They begin early to beat the heat!” Velma Schnoll,  Biodiversity Education Project Manager16 April 2012

Roberta Ayres, Senor Science Educator, informs me that as of now (18th April) we have done in-class presentations to 1,327 3rd grade students.. and tomorrow we still have the town of Trindade to do in Sao Tome!  Next week we will do the same in Principe. A science update comes next. Some exciting stuff.

The Race: Gulf of Guinea VI, First week

Having completed my lectures at CIBIO near Porto, and in the symposium on Sao Tome and Principe in Lisbon, I hooked up with Drs Tomio Iwamoto, Brian Simison, and James Shevock, Miko Nadel and our outstanding photographer, Andrew Stanbridge in the Lisbon airport whereupon we paid gobs of money in overweight charges to TAP airlines (coloring books). The first six of us arrived at the Omali and have been working in various sites for a week until we were joined by Rayna Bell on the Friday morning flight. Rayna is the Cornell grad student who is looking at some interesting genetic problems with the treefrogs here. Early on I paid visits to Arlindo Carvalho, Director General of the Ministry of the Environment and Victor Bonfim, Director of Conservation to pay our respects and request our authorizations.

All of the photos below are by Andrew Stanbridge.

So far, we have found no limpets! Small barnacles, yes; marine mollusks, yes; but no true limpets. Brian is pretty much sampling everything but his specialty critters do not seem to be here. Whether or not there is some chemical feature of the volcanic rock that renders the rocks uninhabitable remains a question. Perhaps Principe will be different.

Jim Shevock has already found two bryophyte families new to the islands, both on the Macambrara road at about 1100 meters. This is Jim’s second trip; in GG IV, he made some 800 collections, so this is stuff we missed.

Miko Nadel, our grad student from San Francisco State, is conducting what we think is the first lichen survey ever of these oceanic islands- so everything is kind of new.

Tomio Iwamoto, veteran of GG I and II is working closely with the Department of Fisheries and an NGO called MARAPA to produce a guide primarily for the local fishermen.

Yesterday, after Rayna’s arrival, we went up to inspect the large Olea tree which is our one locality for the unique Hyperolius thomensis. Like last year, we found no adults but there were old egg masses in both tree holes, and definitely tadpoles in one of them. The rains are upon us, and we are hoping that during the next couple of weeks the other smaller green species will appear. We are being assisted by old friends and a new one, a young Portuguese graduate named Joao Pedro Pio who works with Mariana Carvalho on the endemic maroon pigeon. I think Rayna and I, Pedro and a local guy from Nova Moca will go up at night to Lagoa Amelia (nearly 1500 meters) to try to collect Hyperolius molleri.

Tuesday, the two botanists and Andrew will go up to the top of the Pico, an area we have never collected. We are being taken there by our friends from Tropic Ventures, Andre, Hugo and Maneh. At the same time, Rayna and I will go out to Rolas Island to look for caecilians. They were collected on the island many years ago and we wish to add them to our genetic map of this unique species.

Here’s the parting shot.

The Race: Gulf of Guinea VI, Part II. (Sharing the Wealth)

eddie-herbst-principe

Principe Island from the northeast.  This island is at least 31 million years old  [Phot. Eddie Herbst]

Some years ago the Gulf of Guinea Project “morphed” from a pure multidisciplinary research focus to include an additional and parallel effort to share our science with the local people and non-scientists everywhere. My first couple of visits to São Tomé and Príncipe followed over thirty years of fieldwork on the African mainland, essentially doing science that is read and used by other scientists; this had been wonderfully exciting, rewarding and fun (sometimes scary). But my exposure to the islands of São Tomé and Príncipe changed my outlook and to some degree, the direction of my work in a fundamental way.

Here is a tiny two-island nation absolutely unique and rich biologically, yet still poorly known to the world of science. At the same time there is a looming threat to the environment with the recent discovery of off-shore oil, and the real danger that the world might lose this biological richness before it is even discovered and described! Moreover, the delightful citizens of these islands have, by and large, no idea how rich and special their biodiversity heritage is. Perhaps if we could make the citizens aware of what they have that is unique, found nowhere else in the world, they might be in a better position to make informed decisions as change occurs in the future.

Here, I realized, is an opportunity to help an entire nation prepare for change through awareness of the unique nature of their environment. But how?

blog-image

The sharing of knowledge is fundamental to my discipline, and I have always brought or sent copies of our published scientific results to the governments and appropriate institutions of the African countries in which I have worked, but it was not until several years into our islands work that it occurred to me that we should be including a Portuguese abstract in each of our publications (above left). The abstracts at least make our work understandable to Portuguese scholars who read scientific journals, but on the islands, it was only the various ministries and specialists who even received these articles, and they are technical in nature (we have published 18 so far). In 2008, I began to write this monthly blog (above right). While it is written for a popular audience and hopefully helps bring world attention to the biological uniqueness of the islands, it is still only available to English speakers with access to the worldwide web.

Visitors to the California Academy of Sciences are aware of our work in the islands as we occasionally have small semi-permanent exhibits on our island work on the public floor (see below)

ex

I should mention that the Academy is nearly 160 years old, and we receive over one and a half million visitors per year. We have frequent after-hour public and fundraising events, and whenever possible we have a Gulf of Guinea Islands display which give those of us who are involved an opportunity to describe our research to our public in person.

exped-nite

Velma Schnoll at Discovery Evening. March 2, 2012 (Phot. RCD)

While these events help make our local visitors aware of our island work, they obviously have only indirect impact to our island friends.

During expeditions in the past few years we have been interviewed by local media (radio and television) and have been asked to give lectures on biodiversity at a number of schools and institutions, especially at the Instituto Superior Politecnico, thanks to Dra. Alizira Rodriguez, and also at a biodiversity conference under the auspices of Regional President Tosé Cassandra of Príncipe.

isp-lecture-1690

Local high school lecture (Phot A. Stanbridge, GG V)

These have been excellent opportunities to communicate directly to advanced students and conservation workers (through a translator), but the information still does not get down to the fishermen, the kids, or the people in the market places.

Sometime in 2010, before GG IV, it occurred to me that we might be able to reach the local populations visually. One of the things we have that nobody else has is outstanding images, not just of pretty beaches and Câo Grande, but of the unique living plants and animals themselves! And we know what they are, and sometimes where they came from. So, I put together a series of powerpoint mockups of colorful biodiversity posters on my laptop, and during GG IV Ishowed them to everyone who would look; they all seemed to like the colorful montages.

During GG IV, one of the expedition members was Roberta Ayres, MSc., an Academy educator who runs our nature center (see earlier blogs). Roberta’s mission was to assess the level of knowledge of biodiversity in the islands’ school system, assess the likely impact of the posters, and to discover what else we might do to raise biodiversity awareness through the schools. I have written a number of blogs about how the posters were ultimately produced, thanks largely to the efforts of Velma Schnoll, Docent Coordinator and Jim Boyer of our CAS Docent Council (see below) and with funding from STeP UP.

posters-only

Posters, GG V. from V. Schnoll presentation, 2011.

Gulf of Guinea Expedition V was a largely educational mission dedicated to the distribution on both islands (see earlier blogs) of the 200 posters we produced, and this was accomplished by Mrs Schnoll, Andrew Stanbridge (our photographer), and I, along with a host of local friends, including Marnie Saidi of Príncipe and Antonio Fernando of São Tomé. A very central figure in all of our endeavors, both scientific and educational since the very first expedition in 2001 has been Quintino Quade of STeP UP. Readers will know that he appears in virtually every blog since the first one.

dist-collage

At the same, we continued to pursue information on our ultimate goal which is the creation of a Gulf of Guinea Biodiversity Center, a place on the islands where the citizens can access all of the information being gathered about the environment, and which can serve as a clearing house for all science and natural history research on the islands. Over the years, we have shared this idea with many citizens and foreign researchers on São Tomé and Príncipe.

In Part I of this blog, I described the scientific goals of GG VI (which begins next month) and introduced the investigators who will be on the expedition. The education component (Part II) is meant to build upon the efforts of GG V, and two educators will be coming along as well: Roberta Ayres (GG IV) and Velma Schnoll (GG V).

Like the overall project, our biodiversity education efforts have morphed into a team with Mrs. Velma Schnoll as Biodiversity Education Project Manager. After much debate (including the possibility of an animated cartoon), the team decided to produce 2,000 coloring books for young elementary school students, featuring the same endemic species that appear on the posters of last year. We have selected four primary schools on São Tomé and, of course, the one in Santo Antonio, Príncipe as our trial sites.

Thanks to Mike Murakami’s friend, Richard Engle, proprietor of Solstice Press, Oakland California, we got a very favorable discount on the printing costs. So, here is what they will look like:

stp-front-cover-faded1

The front cover artwork is by Sean Vidal-Edgerton. Sean and Corlis Schneider (back cover art) were both in a biological illustration program at the University of California at Santa Cruz, and California State University, Monterey Bay. In 2011, this group produced a wonderful on-line account of our São Tomé and Príncipe biodiversity research: http://sciencenotes.ucsc.edu/2011/pages/eden/eden.html We were extremely fortunate that they joined us.

ibc

The inside back and front covers have color images of the same living plants and animals that are illustrated in the cartoons.

contents-overview

This is a spread of the full contents of the book; except for the first two pages, the cartoons will not necessarily be in this order. The two game pages will be in the middle of the book.

Here are a couple of Jim Boyer’s fabulous cartoons as they will appear as full pages:

sele

Back cover Sao Tome e Principe coloring book

Again, the back cover artwork is by the talented artist, Corlis Schneider. As the logos indicate, much of the production costs of this project have been provided by a Goldman Fund donation to STeP UP, one of our main partners on the islands. Africa’s Eden is already well known to readers of this blog; the rest of us are volunteers.

So, Part II of Gulf of Guinea Islands Expedition VI is the distribution of the coloring books. Moreover, Roberta Ayres and Velma Schnoll have produced a teacher’s guide incorporating both the books and the posters with island evolutionary principles, and they hope to conduct a workshop for teachers in São Tomé and later on Príncipe.

Now, all we have to do is get 2,000 of these books to the islands by hand, and somehow procure enough colored pencils (crayons do not work well on the Equator) over there for the kids.

As usual I will post from the islands.

Here’s the parting shot:

The Race: Gulf of Guinea VI, Part I (the Science)

Things have been very busy here at the Academy of Sciences, and this is one of my tardier blogs! However, part of the hustle and bustle has been in planning our next expedition, Gulf of Guinea VI.

The first good news is that our new species of gecko from Príncipe is about to be formally published in the African Journal of Herpetology, possibly as soon as April. It is bad luck to give you its name before it is published, but here is what it looks like, and we are adding yet another endemic species to our wonderful islands!

As readers know, our expeditions have largely been privately funded since GG III, and the friends who have helped us are always celebrated in the PARTNERS section below.  However, I am going to take this early opportunity to thank the folks who are making the upcoming expedition financially possible: The Herbst Foundation, The “Blackhawk Gang,” the Docent Council of the California Academy of Sciences in honor of Kathleen Lilienthal, Prof. & Mrs. Evan C. Evans III, Bernard S. Schulte, John S. Livermore, John and Judy Sears and Elton Welke.

Here are the scientist participants in the upcoming GG VI which will run from 30 March until 5 May.

Dr. Tomio Iwamoto is Curator Emeritus of our Ichthyology Department, and my good friend and flyfishing buddy.  He is a veteran of GG I and GG II and has already published two scientific papers as a result of these expeditions. He has also worked with São Tomé and Príncipe fisheries people in deepwater trawling around the islands (see Shipboard Discoveries….June 2010 blog).  During GG VI he wants to visit as many local fishing villages as he can on both islands to see what the most commonly caught fishes are.  His goal is to produce a popular guide for the fishermen themselves! This will not be a scientific publication.

Brian and limpet

Dr. Brian Simison is a world authority on small monovalved molluscs known as limpets, commonly found firmly attached to rocks in the coastal littoral zones.  So far as we know, this group has never before been sampled in São Tomé and Príncipe, and our expectations for new discoveries are high.

lima newshrew

Crocidura tomensis, the Sao Tome shrew. Phot by Ricardo Lima, 2010

Brian is alsoDirector of the Academy’s  Center for Comparative Genomics which is where all our genetic and molecular work is done.  He became involved in our molecular analyses of the true status of the endemic São Tomé shrew (see Unique shrew…. August 2010 blog).  Working with Eden Maloney, he discovered that the shrew on Príncipe, long thought to be a mainland species, may indeed also be an endemic to that island.  While we collected DNA of this second shrew during GG II, we collected no adults.  Assuming we receive permission from the Ministry, Brian and I will also try to secure a couple of adult Príncipe shrews. If this is indeed a unique species, we will need to be able do describe its anatomy formally.

Two graduate students will be joining us.  The first is Rayna Bell who is doing her PhD on African tree frogs at Cornell University.

Rayna will be looking at a potential hybrid zone between the oceanic tree frog (above, Hyperolius molleri) and the flambouyant São Tomé giant tree frog, H. thomensis of higher elevations, which I have featured in many of these blogs.  There is something curious going on with the genetics of these species and one of Rayna’s projects will be to look at both populations from the molecular perspective.

miko and lichens

Miko Nadel and lichens (from web)

Our other graduate student is Miko Nadel, who is doing his MSc in botany at San Francisco State University under the guidance of our favorite mycologist, Dr. Dennis Desjardin, describer of the now infamous Phallus drewesi of São Tomé.  Recall that Drs. Desjardin (GG II & III) and Perry (GG III) learned that over 33% of the mushrooms of São Tomé and Príncipe are new to science.  Miko informs me that there have been only a couple of scientific papers ever written on the lichens of the islands, and that was back in the 1880’s.  So it is time for a more modern and thorough look at this flora.

Finally, we round the scientist group out with the irrepressible  James Shevock, the Academy’s bryophyte (mosses and their allies) expert.

The results of Jim’s efforts during GG IV are summarized in the image below.  The largest uptick of new species for the islands is expected in the third paper, which we hope will be published this year.

The Race: An Embarrassing Surprise in Henrique’s Garden

Last May while still in the islands I wrote a blog entitled “Henrique’s Spider.”  Henrique Pinto da Costa is my good friend and former Minister of Agriculture in the Republic of São Tomé e Príncipe. We are quite close and call each other “Bob 42” and “Henrique 42”, referring to the year of our respective births (There is a mutual friend, “Bruce 42” as well – Bruce Potter, who runs the Island Research Foundation in Washington D.C..

Since we left the islands, Henrique’s brother, Manuel, has been elected the new President of the Republic;  in fact Manuel Pinto da Costa was also the country’s first president after independence from Portugal in 1975.

in-the-garden

“Bob 42″ and “Henrique 42″ in Henrique’s Garden, Sao Tome.  A. Stanbridge GGV

As I wrote some months ago, we found some remarkable spiders of the genus Gasteracantha in Henrique’s garden which I brought back to the Academy for identification as, at the time, I did not recall ever seeing this strange spider on earlier expeditions.

I gave the spiders to our experts in Entomology who tentatively identified them as Gasteracantha sanguinolenta, a very widespread species  on the mainland.

A few weeks ago, another old island friend, Angus Gascoigne of ISP, a lecturer at the islands’ polytecnic institute, asked me if I knew about an endemic island spider called Gasteracantha thomasinsulae; he also pointed out that we, the California Academy of Sciences, actually house the type material, the specimens from which this endemic species was named!  This came as a surprise to the Entomology staff, but then that department houses over 15 million specimens.   Darrell Ubick of Entomology went into our enormous collections, located the type material, compared it with the specimens we brought back and sure enough, Henrique’s spiders are the endemic Gasteracantha thomasinsulae, so far known only from the island of São Tomé and NOT a widespread African species!

Here is Gasteracantha thomasinsulae, an endemic spider  from Henrique 42’s garden: A Stanbridge GG V

These spiders were first discovered by a professional collector named Borys Malkin, who collected a series of them in 1949 for Dr. Ed Ross, one of our entomologists. They were found in a number of localities including Nova Ceilão, Zampalma and Macambrara.  Dr. Ross sent the specimens to Dr. Allan Archer, a specialist at the University of Alabama, who ultimately described them as a new species in 1951.
