Severe Biomass-Burning Aerosol Pollution during the 2019 Amazon Wildfire and Its Direct Radiative-Forcing Impact: A Space Perspective from MODIS Retrievals

Remote Sensing, 2022
An extreme biomass burning event occurred in the Amazonian rainforest from July through September 2019 due to the extensive wildfires used to clear the land, which allowed for more significant forest burning than previously occurred.

Genetic structuring in a Neotropical palm analyzed through an Andean orogenesis‐scenario

Ecology and Evolution, 2018
Andean orogenesis has driven the development of very high plant diversity in the Neotropics through its impact on landscape evolution and climate. The analysis of the intraspecific patterns of genetic structure in plants would permit inferring the ...

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

Frontiers 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.

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

Anais 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

Scientific 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

Bulletin 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

Avocetta
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

Carbon recovery dynamics following disturbance by selective logging in Amazonian forests

eLife, 2016
When 2 Mha of Amazonian forests are disturbed by selective logging each year, more than 90 Tg of carbon (C) is emitted to the atmosphere. Emissions are then counterbalanced by forest regrowth.

Transport of North African dust from the Bodélé depression to the Amazon Basin: a case study [PDF]

Atmospheric Chemistry and Physics, 2010
Through long-range transport of dust, the North-African desert supplies essential minerals to the Amazon rain forest. Since North African dust reaches South America mostly during the Northern Hemisphere winter, the dust sources active during winter are ...

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...
