Litterfall ant genus and abundance in a fertiliser experiment area in Central Amazon, 2018-2019

C.R. Santos Neto, F.B. Baccaro & C.A. Quesada
Data are presented showing litterfall ant species and abundance from a plot based fertilisation experiment. The experiment was carried out at the Biological Dynamics of Forest Fragments Project (BDFFP) approximately 100 km north of Manaus. Data were collected in October 2018 and September 2019 by Santos-Neto. Sampling was carried out using a Wrinkler extractor. The data were collected to investigate the possible effects of different fertiliser applications on litterfall ant species and abundance. The work...

Genetic structure in populations of Euterpe precatoria Mart. in the Brazilian Amazon

Santiago Ramos & Maria Lopes
Euterpe precatoria is a palm tree belonging to the Arecaceae family, occurring in Western and Central Brazilian Amazonia Its fruit, which is very appreciated in the Amazon region, produces pulp that is consumed in fresh form. Its production is carried out almost exclusively by extractive farmers. In order to establish adequate strategies to sustain this genetic resource. We need knowledge about its diversity and genetic structure in natural populations. This study aimed to evaluate the...

Diversification history of clown tree frogs in Neotropical rainforests (Anura, Hylidae, Dendropsophus leucophyllatus group)

Renata Pirani, Pedro Peloso, Joyce Prado, Érico Polo, Lacey Knowles, Santiago Ron, Miguel Rodrigues, Marcelo Sturaro & Fernanda Werneck
General consensus emphasizes that no single biological process can explain the patterns of species’ distributions and diversification in the Neotropics. Instead, the interplay of several processes across space and time must be taken into account. Here we investigated the phylogenetic relationships and biogeographic history of tree frogs in the Dendropsophus leucophyllatus species group (Amphibia: Hylidae), which is distributed across Amazonia and the Atlantic rainforests. Using Next Generation Sequencing (NGS) and double digest restriction-site associated DNA...

Data from: Paleoclimatic evolution as the main driver of current genomic diversity in the widespread and polymorphic Neotropical songbird Arremon taciturnus

Nelson Buainain, Roberta Canton, Gabriela Zuquim, Hanna Tuomisto, Tomas Hrbek, Hiromitsu Sato & Camila Ribas
Several factors have been proposed as drivers of species diversification in the Neotropics, including environmental heterogeneity, the development of drainage systems and historical changes in forest distribution due to climatic oscillations. Here, we investigate which drivers contributed to the evolutionary history and current patterns of diversity of a polymorphic songbird (Arremon taciturnus) that is widely distributed in Amazonian and Atlantic forests as well as in Cerrado gallery and seasonally-dry forests. We use genomic, phenotypic and...

Juggling options: manipulation ease determines primate optimal fruit size choice

Renann H. P. Dias-Silva, Matheus J. Castro Sa, Fabricio B. Baccaro, Pavel Tománek & Adrian A. Barnett
Optimal foraging theory predicts that animals will seek simultaneously to minimize food processing time and maximize energetic gain. To test this hypothesis, we evaluated whether a specialist seed-predator primate forages optimally when choosing among variable-sized thick-husked fruits. Our objects of study were the golden-backed-uacari (Cacajao ouakary, Pitheciidae) and single seeded pods of the macucu tree (Aldina latifolia, Fabaceae). We predicted that golden-backed-uacari will consume fruits of the size class that requires the least time to...
