Last Thursday 30th of November and Friday 1st of December, a group of researchers and students from different institutions meet to celebrate the IV meeting of the (Spanish) Tropical Biology Group (REDTROP). The workshop was very interesting, with presentations about research conducted on different taxonomic groups, including myxomycetes, invertebrates, plants, bryophytes, mammals, reptiles and amphibians. Presentations did also show studies conducted on different tropical regions, from Madagascar to Costa Rica, passing through Senegal, Peru, Brazil or Mexico. The full program is available here. We wish next year we will be as many people as this year, and with the same level of enthusiasm. If you are interested in tropical biology research we expect you next year in the V meeting of the Tropical Biology Group.
