“…In the Caatinga and Cerrado, most of the threatened species' landscapes have <30% of habitat cover, where biodiversity persistence drops sharply (Arroyo‐Rodríguez et al ., 2020). For these regions, where matrix quality is lower for primate species, raising the extinction threshold is still recommended as a conservative strategy (Sobrinho et al ., 2016; Silva & Barbosa, 2017; Rausch et al ., 2019; Arroyo‐Rodríguez et al ., 2020). Since the landscape and life history attributes may change the way in which they associate with the extinction risk gradient, this will generate different conservation priorities among the species in each biome.…”

Brazilian primates differ regarding landscape characteristics within their ranges (e.g. habitat availability) and life‐history traits (e.g. body size). These landscape and life history attributes may be related to extinction risk. Here, we verified how such attributes correlate with primate threat categories. We considered 124 Brazilian primates based on the 2014 Brazilian list of threatened (Critically Endangered, Endangered and Vulnerable) and non‐threatened (Least Concern and Near Threatened) species. We then characterized their landscape (i.e. habitat availability, habitat loss and fragmentation, indigenous lands, roads, urban areas, deforestation arch) and life‐history attributes (i.e. body weight, gestation length and generation time), which together make up the threat context for each threat category. We compared threat categories to identify differences in such attributes, considering biome (Atlantic Forest, Amazon, Caatinga and Cerrado) as a factor and testing for phylogenetic effect. We investigated the attributes responsible for group characterization for specific threats and binary threatened/non‐threatened categories. We show that life history and landscape attributes differ across biomes. However, only landscape features varied across biomes. In the Amazon, the threatened categories reached the highest level of habitat loss in the last 30 years, while in the Atlantic Forest, the landscape of threatened species had the highest proportions of roads and urban areas. Most threatened species landscapes in the Caatinga and Cerrado were highly fragmented. We found a positive link between human impacts and extinction risk in the Amazon. In the other biomes, anthropogenic landscape characteristics were associated with threatened and non‐threatened species. Threatened species tended to have large bodies and a slow life history, regardless of the biome. The more closely related the species, the more similar the traits. We suggest considering biomes and threat categories together with specific landscape and life history attributes to distinguish primate threat context for species conservation priority‐setting.

“…Cerca de 70% da precipitação na Caatinga ocorre em um único mês(DE ANDRADE et al, 2017). As secas recorrentes podem durar anos e têm sido repetidamente responsáveis pela perda de colheitas, animais e vidas humanas, bem como pelo êxodo rural para grandes centros urbanos(DA SILVA et al, 2017a;DA SILVA et al, 2017b;BRAGAGNOLO et al, 2017;DA SILVA et al, 2020). Cerca de 94% da Caatinga apresenta risco moderado a alto de desertificação e é uma das vegetações mais sensíveis às mudanças climáticas no mundo(KASECKER et al, 2018).…”

A erosão é a principal forma de degradação do solo no mundo, sendo a hídrica a mais predominante no Brasil. Este trabalho teve o objetivo quantificar a perda de fósforo associada pulsos de precipitação em áreas com diferentes tipos de cobertura vegetal, sendo P1 = Solo sem vegetação, P2 = solo sobre cultivo da palma forrageira e P3 = solo sobre vegetação nativa preservada. Durante o desenvolvimento da pesquisa, parcelas de perda de solo foram instaladas na área experimental do Centro de Desenvolvimento Sustentável do Semiárido da Universidade Federal de Campina Grande, no município de Sumé, cariri paraibano. Os resultados mostraram que P1 apresentou as maiores quantidade de produção de sedimento, aproximadamente 1,4 t/ha, seguida da P3, com 0,88 kg/ha e P2 com 0,29 kg/ha. Quanto a lâmina escoada, na P1 foi constata do uma lâmina de 13,7 mm, seguida da P2 e P3, as quais apresentaram 0,277 e 0,042 mm respectivamente. Portanto, solos descobertos sofrem constantes perdas de material, apresentando maior produção de sedimentos, lâmina escoada e maior número de fósforo solúvel perdido, por outro lado a vegetação nativa conservada protege o solo e promove a permanência do fósforo naquele solo.
