Testing a global standard for quantifying species recovery and assessing conser...

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a "Green List of Species" (now the IUCN Green Status of Species). A draft Green Status framework for assessing species' progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e.,...

Short term patterns of germination in response to litter clearing and exclosure...

Efforts to restore tropical forest ecosystem services depend on understanding the barriers to germination of species of economic and cultural interest. Here we use two important non-timber forest product species (NTFP: Inga capitata. Desv. – Fabaceae and Euterpe oleracea Mart. – Arecaeae) to compare germination across a forest regrowth gradient in the northeast Brazilian Amazon. Experimental treatments were use...

Towards monitoring biodiversity in amazonian forests: How regular samples captu...

Background: Ecological monitoring and sampling optima are context and location specific. Novel applications (e.g. biodiversity monitoring for environmental service payments) call for renewed efforts to establish reliable and robust monitoring in biodiversity rich areas. As there is little information on the distribution of biodiversity across the Amazon basin, we used altitude as a proxy for biological variable...

Ecological relationships of meso-scale distribution in 25 neotropical vertebrat...

Vertebrates are a vital ecological component of Amazon forest biodiversity. Although vertebrates are a functionally important part of various ecosystem services they continue to be threatened by anthropogenic impacts throughout the Amazon. Here we use a standardized, regularly spaced arrangement of camera traps within 25km2 to provide a baseline assessment of vertebrate species diversity in a sustainable use pr...

Amazonian rainforest tree mortality driven by climate and functional traits

Artificial nest predation rates vary depending on visibility in the eastern Bra...

Estudos de observação e experimentais demonstraram que ninhos de aves menos visíveis apresentam taxas de predação reduzidas. O objetivo do presente estudo foi avaliar diferenças nas taxas de predação entre duas manipulações experimentais de ninhos artificiais no chão (i.e., limpando uma área em torno do ninho artificial ou deixando o mais natural possível), e testar se variáveis ambientais também poderiam afeta...

Richness and composition of vertebrates in active and inactive latrines of Pter...

This study aimed to evaluate the richness and composition of the medium and large sized vertebrates in active and inactive latrines of Giant otters [Pteronura brasiliensis (Gmelin, 1788)] in a Sustainable Use conservation unit in the Eastern Brazilian Amazon. The study was performed in 45 latrines along 230 km of the Falsino and Araguari rivers (0°55'N, 51°35'W) and from this total, 24 presented fresh feces of ...

Socio-economic and spatial determinants of anthropogenic predation on Yellow-sp...

Human expansion has drastically affected wildlife species across Amazonian waterways and the continued increase in rural populations across Amazonia is likely to increase pressure on widely exploited chelonian species. The lack of information evaluating determinants of human consumption patterns limits the effective implementation of conservation strategies. Our objective was to determine the relative importanc...

Diversity of terrestrial mammal seed dispersers along a lowland Amazon forest r...

There is increasing interest in the restoration/regeneration of degraded tropical habitats yet the potential role of natural regenerators remains unclear. We test the hypothesis that the richness and functional diversity of terrestrial mammals differs between forest regrowth stages. We quantified the richness and functional diversity of eight terrestrial mammal seeddisperser species across a forest regrowth gra...

Model thresholds are more important than presence location type: Understanding ...

Modeling the distribution of rare and endangered species is challenging, and there is substantial debate regarding what species distribution models (SDMs) actually represent. Here I investigated whether locations of different lowland tapir signs (feces, trails and tracks) generated different distributions of suitable habitat using a presence-only species distribution modeling technique. Comparison of the equiva...
