Evolution 2015
O evento internacional Evolution 2015 será realizado entre os dias 26 e 30 de junho de 2015 no Casa Grande Hotel Resort em Guarujá, SP e contará com grandes cientistas internacionais que trabalham com evolução biológica <www.evolution2015.org>.
O último dia para submissão de trabalhos a serem apresentados na forma de pôster é 15 de maio.
Brasileiros e estrangeiros que residem no Brasil tem um desconto especial na inscrição. Para fazer uso deste desconto, faça sua inscrição no site <www.evolution2015.org> e coloque o voucher "Brazil1" se for pesquisador, pós-doc, ou aluno de pós-graduação, ou "Brazil2" se for aluno de graduação.
O evento terá 8 simpósios principais, escolhidos pelas sociedades patrocinadoras:
Temperate Assumptions (Organizer: Marlene Zuk)
Contributions from Naturalists to the Fight Against Dengue in Brazil and Beyond (Organizers: Alex Perkins and Louis Lambrechts)
Frontiers in Parametric Biogeography (Organizers: James Albert and Alexandre Antonelli)
Breaking Barriers: Empirical, Theoretical, and Gender Issues in Phylogenetics (Organizers: Corrie S. Moreau, Brian C. O’Meara, Susan L. Perkins, and Tracy A. Heath)
Prokaryote comparative genomics, phylogenetics, and evolution (Organizers: José S. L. Patané and João Carlos Setubal)
Iconic Brazilian ecosystems as case studies for teaching evolution (Organizers: Thomas R Meagher, Eimear Nic Lughadha and Louise Mead)
Epigenetics and Evolutionary Processes (Organizers: Joshua Banta and Christina Richards)
The multiple dimensions of biodiversity science (Organizers: Ana Carnaval and Christopher Dick)
When Gene Flow Really Matters: Gene Flow and Applied Plant Evolutionary Biology (Organizer: Norman Ellstrand)
Este evento é sempre uma ótima oportunidade para a integração de diversas áreas da biologia que acabam ficando separadas por motivos históricos, como a genética, evolução, ecologia, taxonomia, sistemática, botânica e zoologia.

Treetop shelter of a Neotropical River Otter cuba (Lontra longicaudis - Carnivora: Mustelidae) in an Amazonian flooded forest
SANTOS, P.M.R.S.; KINUPP, V.F.; COLETTO-SILVA, A. 2007. Treetop shelter of a Neotropical River Otter cuba (Lontra longicaudis - Carnivora: Mustelidae) in an Amazonian flooded forest. Acta Amazonica 37(2):309-312.
Abstract. The finding of a Neotropical river otter (Lontra longicaudis) cub occupying a shelter in a hollowed treetop is reported. The observation was made in a seasonally flooded forest in Central Amazonia, during the high water peak of the annual inundation cycle. A literature review indicates that this is the first description of a shelter of the species, both in a hollowed tree and in Amazonia. This observation can indicate a strong relationship between the species’ breeding cycle with the annual dynamics of Amazonian rivers. We discuss potential advantages and disadvantages of breeding when water level is high.

Diet of racoon Procyon cancrivorus (Carnivora, Procyonidae) in a mangrove and restinga area in Espirito Santo state, Brazil
MARTINELLI, M.M.; VOLPI, T.A. 2010. Diet of racoon Procyon cancrivorus (Carnivora, Procyonidae) in a mangrove and restinga area in Espirito Santo state, Brazil. Natureza on-line 8(3):150-151.
Abstract. Diet of Procyon cancrivorus was analised from fecal material. From 47 analyzed fecal samples, the most consumed items were Arthropods, found in 100% of scats, followed by Allagoptera arenaria (guriri-coconut), in 50.8% of scats, and small vertebrates and seeds, found in 4.3% of scats each. Among the arthropods, the most frequent crab family was the Ocypodidae, found in all samples.

Nota sobre convergência e divergência alimentar de canídeos e felídeos (Mammalia: Carnivora) simpátricos no Cerrado brasileiro
TROVATI, R.G.; CAMPOS, C.B.; BRITO, B.A. 2008. Nota sobre convergência e divergência alimentar de canídeos e felídeos (Mammalia: Carnivora) simpátricos no Cerrado brasileiro. Neotropical Biology and Conservation 3(2):95-100.
Abstract. Feed convergence and divergence of some sympatric canids and felids in Tocantins, Brazil were analyzed. Thirty-six fecal samples were collected. The results showed that 37.3% of the canids’ diet was made up of fruit and fibers (grasses e peel fruits) and 44% of the felids’ diet was made up of mammals. There were differences in the measurement and in the overlap of trophic niche, indicating canids as generalists and felids as specialists. Feeding of Phantera onca was more divergent and feeding of Puma yagouaroundi converged with the canids. Thus, the data collected shows that small felids have a similar diet to canids and only large and medium felids present divergence, but further studies are needed to better elucidate the degree of sympatric of these animals.
