The Race: Mountains That Glow

Drs. Brian Simison and Tomio Iwamoto and Roberta Ayres and Rayna Bell left early this morning on the TAP flight for home; five of us remain: our two botanists on Principe and three of us here on Sao Tome continue.  It is time for a science update, especially since it is pouring rain as I write, and our biodiversity education mission on the big island is completed for now.

science-1-of-1

Last week, and for the first time, Academy scientists collected the top of Pico do Sao Tome. At over 2,000 meters, the peak is remote and can be quite dangerous to ascend in the rainy season, especially carrying equipment. Our guys were able to accomplish this with help from our friends, Andre Reis, Hugo Serodio and Antonio Fernandes. Andre runs Tropic Ventures, a new company that provides various tourist activities including car rentals, water sports, etc but they also take on really hairy missions into the interior of the island. Andre is ex-military (Portuguese) and his company, equipment and skills are very, very good.

After a postponement due to the rains, Jim Shevock, Miko Nadel, and our photographer Andrew Stanbridge made two-day ascent, collecting all the way.

pico-1-of-1

Those who know Jim Shevock, the Academy’s moss expert, will not be surprised to learn that he went nuts. I have no idea how many moss specimens he got nor how many are new, but to say he was enthusiastic upon their return would be a gross understatement.

But the neatest discovery was made by Miko Nadel, our lichen grad student from San Francisco State.  Sitting and eating dinner in the darkness, Miko looked down and thought he saw Andrew’s wristwatch on the ground, glowing at his feet. What he soon discovered was not Andrew’s watch but a patch of  bioluminescent mushrooms!

Miko’s graduate advisor, Dr. Dennis Desjardin, a world authority on mushrooms, was with us on GG II and GG III and made the first comprehensive survey of both islands. But , curiously, Dennis (a Fellow of CAS) has recently been doing cutting edge research on bioluminescent mushrooms! So I waited until Dennis gave his OK, before posting Andrew’s images of these remarkable fungi. As usual, we will not know what all this means until we return to CAS for analysis. That is how science works.

rayna-1-of-1

Rayna Bell’s mission was to examine the possible hybridization between the Sao Tome giant treefrog, Hyperolius thomensis and the oceanic treefrog, H. molleri.  We have had genetic and phenotypic hints that this might be happening for some time now.  Rayna’s PhD thesis at Cornell is on the evolution of sexual dichromatism in African treefrog species.

frog-1-of-1

It looks as though hybridization is indeed going on between the two species at about 800 to 900 meters. Rayna was able to get samples of the giant frog at 1400 meters and then sampled “downhill” at various elevations to nearly sea level, in oceanic treefrog territory.  We had great help from Joao Pedro Pio, a young Portuguese friend who is working on the endemic maroon pigeon; lucky for us, he loves adventure and frogs.  Rayna is tireless, bright and fun to be with; but among us bush herpetologists, the real test is how one does in the boonies. She is wonderful; I was proud to have her along with us.

And by the way, last night (Rayna’s last), she and Andrew visited the “magic tree” where we have always found the giant treefrog.. they came in about midnight, and told me that as they sat next to the tree, waiting for frogs, the entire forest floor around them was aglow!

It is still raining and outside my door, a Sao Tome prinia is hopping around in the bushes; I will let Andrew’s pictures speak of Tomio Iwamoto and Brian’s adventures in Micoló catching mudskippers and pipefish.

“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.

Andrew Stanbridge continues to take brilliant pictures. He is much more of an asset to us than just his fabulous shots.

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.
