Extinction risk has not been evaluated for 96% of all described plant species. Given that the Global Strategy for Plant Conservation proposes preliminary conservation assessments of all described plant species by 2010, ...

Habitat loss and fragmentation exert unquestionable negative effects in a wide range of taxa on both regional and local scales. However, there is a debate over whether habitat change impacts geographic species distribution. ...

Climate change and habitat loss are key threats to biodiversity, by acting as controlling factors of species’ distributions. In this study, we combined ecological niche modeling with an innovative range-diversity analysis, ...

Ectothermic organisms strongly depend on temperature, making them an excellent model to study the impact of global climatic change (GCC). Under global warming, species may be forced to move toward colder environments, such ...

Orthophytum is a bromeliad genus restricted to Brazil with records for the states of Paraiba, Pernambuco, Alagoas, Sergipe, Bahia, Espirito Santo and Minas Gerais. The genus is usually divided in two informal groups based ...

The calculation of autoecological data, such as optima and tolerance ranges to environmental variables, can be useful to establish the distribution and abundance of the species. These calculations, although mathematically ...

Detailed large-scale information on mammal distribution has often been lacking, hindering conservation efforts. We used the information from the 2009 IUCN Red List of Threatened Species as a baseline for developing habitat ...
