15 Days, Over 1,000 Species

The dive gear has dried in the sun. The collections are packed away. It's time for my last entry before returning home.

In 15 days, 5 divers collected, cataloged, and photographed over 1000 species of invertebrates from the coastal waters of Nosy Be, Madagascar. Our main targets were echinoderms, mollusks and crustaceans, though we collected many interesting animals from other groups as well. Our suspicion is that we have species of sea stars, shrimp and sea cucumbers new to science, including the one in the photograph:



Despite intensive assessment of a relatively localized area--never venturing farther than a two-hour dinghy ride from the research station--we were still picking up new trip records on the last day of diving. Many of these were not just small critters but also large and conspicuous echinoderms. This suggests that we did not reach a point at which the addition of new species records was abating. How welcome and useful it would be therefore to return here for more research!

Just as the marine biodiversity did not disappoint in this rich corner of the Indian Ocean, we were equally fortunate in having consistently great weather and CNRO as our base of operation. We were treated superbly by all the staff, and were not wanting for much. They have an incredible knowledge about their living marine resources, and I am indebted to the kindness they showed us during our stay.

On to the publications! I leave you with these photos from our trip.

A Three-Week Expedition is Underway

This weekend a team of researchers are taking off for Nosy Be, Madagascar. The northwest corner of the island has been identified as a biodiversity hot spot for both terrestrial and coastal marine biodiversity. The area is home to high numbers of unique forms of life and is under high environmental threat.

I will be among the researchers accompanying Dr. Gustav Paulay of the Florida Museum of Natural History on this mission. I will work with Dr. Paulay to collect samples of sea cucumbers and other species for biodiversity characterization at the organismal and genetic scales. Our contribution is part of a larger land-sea biodiversity assessment of the southwest Indian Ocean, coordinated by two researchers at the University of Reunion.

The broader study (BIOTAS) is seeking to not only characterize biodiversity in this part of the world but also to examine the natural organisms. The study will lead to greater understanding of how evolutionary processes shape species assemblage in the region and between its islands, and help identify conservation priorities.

My day to day routine will consist of diving, collecting and documenting species. I will be updating this blog from a satellite phone during the course of the expedition, and I look forward to sharing my observations on the invertebrate species we find.
