Phylogeography of a Typical Forest Heliothermic Lizard Reveals the Combined Influence of Rivers and Climate Dynamics on Diversification in Eastern Amazonia

open access: yesFrontiers in Ecology and Evolution, 2022
The formation of the Amazon drainage basin has been considered an important driver of speciation of several taxa, promoting vicariant events or reinforcement of barriers that restrict gene flow between opposite river margins.

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]

open access: yes, 2011
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.

Effects of forest fragmentation on the vertical stratification of neotropical bats [PDF]

open access: yes, 2020
Vertical stratification is a key component of the biological complexity of rainforests. Understanding community- and species-level responses to disturbance across forest strata is paramount for evidence-based conservation and management.

Changes in the carbon balance of tropical forest: evidence from long-term plots [PDF]

open access: yes, 1998
The role of the world’s forests as a “sink” for atmospheric carbon dioxide is the subject of active debate. Long-term monitoring of plots in mature humid tropical forests concentrated in South America revealed that biomass gain by tree growth exceeded ...

Increasing biomass in Amazonian forest plots [PDF]

open access: yes, 2004
A previous study by Phillips et al. of changes in the biomass of permanent sample plots in Amazonian forests was used to infer the presence of a regional carbon sink.

First record of Dermanura gnoma for the threatened Pernambuco Endemism Center, northern Atlantic Forest, with phylogenetic insights [PDF]

open access: yesAnais da Academia Brasileira de Ciências
Dermanura gnoma (Handley, 1987) is a phyllostomid bat that occurs in South America. In Brazil, most of the records are concentrated in the Amazon Forest, with sparse data from Cerrado and Atlantic Forest. This study presents the first record of D.

Soil chemical attributes in areas under conversion from forest to pasture in southern Brazilian Amazon

open access: yesScientific Reports, 2022
The south of the Brazilian Amazon is one of the largest cattle-producing regions in Brazil, however, most of the pastures are in low fertility soils. Thus, cattle breeders compensate for the low production of pastures, increasing the size of the areas ...

A systematic reassessment and paleogeographic review of fossil Xenarthra from Peru

open access: yesBulletin de l'Institut Français d'Études Andines, 2004
A revision of Peruvian Xenarthra and the discovery of new specimens have increased our knowledge of the Order in this country. About thirty sites from three geographic regions, Amazonian Forest, the Andes, and the coast have yielded Xenarthra in Peru ...

New extra-Amazonian records of the Black-billed Cuckoo Coccyzus erythropthalmus (Cuculidae) for Brazil

open access: yesAvocetta
The breeding grounds of the Black-billed Cuckoo Coccyzus erythropthalmus encompass a wide area in northern North America. During the austral winter individuals migrate to non-breeding areas in South America. There had been only three known locations for
