Article
Avoiding extinction rate is a challenge for scientists and decision-makers. In turn, identifying vulnerable species is a key step towards a consistent strategic planning and programming for species conservation. Rare species are of great interest to scientists because they are more prone to extinction. Rabinowitz proposed that rarity arises from th...

Rarity has long been a question of great interest in a wide range of fields. A method to classify rare species should be simple and easy for different professional groups to learn. Rabinowitz is not only easy-to-follow but also one of the most accepted methods to classify rare species. This study proposes a rarity index (rr) based on Rabinowitz’s s...
Article
As a result of anthropogenic pressure, three drives are expected to affect Brazilian savannas: an increase in the dry season, more frequent fire events, and defaunation. These drivers are a trigger for biodiversity loss and undermine the ecosystems services like carbon storage. Here our goal was to analyze how these drivers can affect the structure...
Article
Climate change impacts are important in shaping large ecotones, such as the transition zone between the Cerrado and Amazon rainforest (CAT) biogeographical domains. The accelerating rate of conversion of native vegetation, the most important factor for biodiversity loss in the Anthropocene, compounded by projected climate change impacts, requires a...

The interest in quantifying rare species has been increasing, but less attention has been paid to analysing their conservation status. Here, we used the Rabinowitz method based on geographical range, habitat specificity and population size to classify 2,203 tree species of South American savannas (SAS). We considered species with narrow (stenochori...
Article
Campos de murundus (CM) is a savanna vegetation type of Cerrado which remain flooded in the rainy season. It is considered protected areas in the state of Goiás, Brazil, but are under strong pressure due to the construction of drainage ditches around them. In this study we compared sampled and estimated species richness, structure and vegetation dy...

The Cerrado complex is covered by twelve physiognomies characterized by a gradient of grassland, savanna and forest formations. We assessed the recruitment (RI) and mortality (MI) of individuals and the gain (BG) and loss (BL) of basal area in the Cerrado complex. We used 26 sites classified into savanna (15) and forest formations (11); dry (19) an...

Many locally and regionally rare species are not covered by red lists, thus compromising conservation strategies. This is the case with ecotones. After applying three rarity criteria based on both geographic range and on local occurrences to 1755 species of a large transitional zone in South America, we discuss how the priority hierarchy found in t...

O objetivo da proposta é predizer possíveis efeitos das mudanças climáticas sobre a distribuição e diversidade de espécies vegetais na zona de transição entre os domínios do Cerrado e da Amazônia. Utilizaremos algoritmos de modelagem de distribuição potencial de espécies considerando cenários climáticos futuros otimistas e pessimistas fornecidos pelo IPCC – Painel Intergovernamental sobre Mudanças Climáticas. Esperamos gerar subsídios para o planejamento adequado de novas unidades de conservação na região, o que possibilitará a proteção de sua rica biodiversidade.
