Environmental monitoring of soil carbon and ecosystem productivity across land use systems in the Atlantic Forest of Brazil

Abstract Tropical ecosystems play a fundamental role in the global carbon cycle due to their high productivity and capacity to store carbon in vegetation and soils. However, land use change has substantially altered these processes, particularly in highly fragmented regions such...

On the validity of Plecturocebus parecis Gusmão et al., 2019, a titi monkey described from southwestern Brazilian Amazonia

Abstract Plecturocebus parecis was described from the southwestern Brazilian Amazon, but its taxonomic status was subsequently questioned after mitochondrial evidence prompted alternative hypotheses regarding species limits within this complex. We reassessed these hypotheses usin...

Morphological and Molecular Evidence Supports Recognition of Austrochondria Gen. Nov. (Rhodomelaceae, Rhodophyta) for the Chilean Endemic Laurencia chilensis

Many red algal species described solely from morphology have historically been assigned to inappropriate genera because of superficial morphological similarity. Laurencia chilensis, originally described for specimens from Chile, has long been recognized as the only representative...

Seven years of monitoring the demography and population density of jaguars (Panthera onca) in a human-modified landscape of eastern Amazonia

The primary impacts of mining on wildlife are habitat loss and fragmentation, which reduce the availability of essential resources and disrupt ecological processes necessary for species persistence. Despite the growing expansion of mining activities in tropical regions, their eff...

The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “ Riolestes capricornicus ” (Goin et al., 2009)

Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “ Ri...

Fire absence favours tree growth above the flame zone threatening South American Cerrado vegetation

Tropical savannas, including the Brazilian Cerrado, face significant woody encroachment linked to fire suppression. We investigated floristic composition, horizontal and vertical structure, and Enhanced Vegetation Index (EVI) time series in a 1-hectare plot within Chapada dos Gui...
