Within-group competition over food resources can be a major cost of social living. In the wild, foragers are confronted with social (e.g. hierarchical rank) and ecological (e.g. food availability and distribution) challenges that affect their foraging decisions and feeding success. Exhibiting prosocial behaviors, such as tolerance at feeding sites, can benefit group members by developing affiliative social relationships, enhancing access to resources and maximizing fitness. We examined social tolerance at feeding sites in Callithrix jacchus,...

Phylogenomic discordance in the Eared Seals is best explained by incomplete lineage sorting following explosive radiation in the Southern HemisphereFernando Lopes, Larissa Oliveira, Amanda Kessler, Yago Beux, Enrique Crespo, Susana Cárdenas-Alayza, Patricia Majluf, Maritza Sepulveda, , Valentina Franco-Trecu, Diego Paez-Rosas, Jaime Chaves, Carolina Loch, Bruce Robertson, Karina Acevedo-Whitehouse, Fernando Elorriaga-Verplancken, Stephen Kirkman, Claire Peart, Jochen Wolf & Sandro Bonatto
The phylogeny and systematics of fur seals and sea lions (Otariidae) have long been studied with diverse data types, including an increasing amount of molecular data. However, only a few phylogenetic relationships have reached acceptance pointing at strong gene-tree species tree discordance. Divergence times in the group also vary largely between studies. These uncertainties impeded the understanding of the biogeographical history of the group, such as when and how trans-equatorial dispersal and subsequent speciation events...
Data from: Flower consumption, ambient temperature and rainfall modulate drinking behavior in a folivorous-frugivorous arboreal mammalÓscar M. Chaves, Vanessa B. Fortes, Gabriela P. Hass, Renata B. Azevedo, Kathryn E. Stoner & Júlio César Bicca-Marques
In these datasets we provided information on the drinking behavior in 14 wild groups of brown howler monkeys (Alouatta guariba clamitans) inhabiting small, medium, and large Atlantic Forest fragments in southern Brazil. We provided two datasets: (1) full data on the drinking behavior of the 14 study groups, and (2) the dataset used to run the GLMMs described in the main manuscript. Overall, we found a wide variation in the mean rate of drinking among...
Negative impacts of dominance on bee communities: Does the influence of invasive honey bees differ from native bees?Lucas Alejandro Garibaldi, Lucas Garibaldi, Néstor Pérez-Méndez, Guaraci Cordeiro, Alice Hughes, Michael Orr, Isabel Alves Dos Santos, Breno Freitas, Favízia Freitas De Oliveira, Gretchen Lebuhn, Ignasi Bartomeus, Marcelo Aizen, Patricia Andrade, Betina Blochtein, Danilo Boscolo, Patricia Drumond, Maria Gaglianone, Barbara Gemmill-Herren, Rosana Halinski, Cristiane Krug, Marcia Maues, Lucia Piedade Kiill, Mardiore Pinheiro, Carmen Pires & Blandina Felipe Viana
Invasive species can reach high abundances and dominate native environments. One of the most impressive examples of ecological invasions is the spread of the African sub-species of the honey bee throughout the Americas, starting from its introduction in a single locality in Brazil. The invasive honey bee is expected to more negatively impact bee community abundance and diversity than native dominant species, but this has not been tested previously. We developed a comprehensive and systematic...
