Speeding up the discovery of unknown plants: a case study of Solanum (Solanaceae) endemics from the Brazilian Atlantic Forest.

(Acelerando a descoberta de plantas desconhecidas: um estudo de caso com espécies de Solanum (Solanaceae) endêmicas da Floresta Atlântica brasileira.) O Brasil possui uma das mais ricas floras do mundo, o que faz com que seja desafiador documentar sua totalidade. Estimativas recentes apontam que as áreas com maior diversidade de plantas devem também conter o maior número de espécies não […]

Restricted geographic distribution of tree species calls for urgent conservation efforts in the Subtropical Atlantic Forest.

The Atlantic Forest encompasses a high level of biodiversity, endemism and degradation; hence, it is a biome of particular interest for biological conservation. We aimed to investigate the actual geographic distribution of tree species and, among the indicator species of each vegetation type, the conservation status and potential distribution of each species along a vegetation […]

Is the current network system of protected areas in the Atlantic Forest effective in conserving key species of bryophytes?

We combined distribution data of bryophyte species with protected areas in the Brazilian Atlantic Forest, using models of potential distribution of species, in order to assess the effectiveness and representativeness of Conservation Units for bryophyte species. We performed potential distribution models for ten bryophyte species classified as bio-indicators for environmental quality and/or endemic to the Atlantic Forest, or […]

Assessing the conservation status of species with limited available data and disjunct distribution.

Current techniques for estimating the extent of occurrence (EOO) of species, especially those with a naturally disjunct distribution and limited available data, lead to overestimations of their geographic distributions. Accurate EOO estimates are of great importance because they are used to assess conservation status. Topological methods, such as those proposed by the International Union for […]

Reassessment of the extinction risk of endemic species in the Neotropics: How can modelling tools help us?

Occurrence data on geographic distribution for most endemic Neotropical plants are scarce and spatially biased, which interfereswith decisions on their conservation status. In this study we present a three-step approach applying: 1) Euclidean Environmental Distance models to search for unknown populations; 2) MaxEnt incorporating additional presence data to produce forecastsof the potential distribution and 3) coupling […]

Paleoecology and radiocarbon dating of the Pleistocene Megafauna of the Brazilian Intertropical Region.

During the Pleistocene a fauna composed of large (biomass>44 kg) and giant mammals (biomass>1000 kg) that are usually associated with open environments lived in the Brazilian Intertropical Region. We present here new information concerning the paleoecology and chronology of some species of this megafauna. Carbon isotope analyses were performed for a better understanding of the paleoecology of the […]
