The conservation status of the world's reptiles
TLDR
The results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Expand
Hyperdominance in the Amazonian Tree Flora
TLDR
The finding that Amazonia is dominated by just 227 tree species implies that most biogeochemical cycling in the world’s largest tropical forest is performed by a tiny sliver of its diversity. Expand
Variation in aboveground tree live biomass in a central Amazonian Forest: Effects of soil and topography
TLDR
This study shows that forests in central Amazonia grow in a heterogeneous environment in relation to soil and topography, and this heterogeneity seems to be in part responsible for differences in structure and AGLB accumulation. Expand
Averting biodiversity collapse in tropical forest protected areas
TLDR
These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines. Expand
Relationships between Habitat Characteristics and Fish Assemblages in Small Streams of Central Amazonia
TLDR
The high between-site turnover in species composition and the strong habitat specificity indicate that it will be necessary to create a network of reserves to efficiently conserve the fish fauna of small forest streams in Central Amazonia. Expand
Markedly divergent estimates of Amazon forest carbon density from ground plots and satellites
TLDR
Pantropical biomass maps are widely used by governments and by projects aiming to reduce deforestation using carbon offsets, but may have significant regional biases and carbon accounting techniques must be revised to account for the known ecological variation in tree wood density and allometry. Expand
Spatial eigenfunction analyses in stream networks: do watercourse and overland distances produce different results?
SUMMARY1. The use of spatial variables is a common procedure in ecological studies. The techniqueis based on the definition of a connectivity⁄distance matrix that conceptually defines thedispersal ofExpand
RAPELD: A MODIFICATION OF THE GENTRY METHOD FOR BIODIVERSITY SURVEYS IN LONG-TERM ECOLOGICAL RESEARCH SITES.
Our objectives were to develop a method that would be appropriate for long-term ecological studies, but that would permit rapid surveys to evaluate biotic complementarity and land-use planning inExpand
Diets of Amazonian Crocodilians
TLDR
There is an inverse relationship between the number of terrestrial invertebrates eaten and thenumber of fish eaten by different size classes of Caiman crocodilus, suggesting that mutually exclusive foraging modes are used for those prey categories. Expand
Persistent effects of pre-Columbian plant domestication on Amazonian forest composition
TLDR
Analysis of plant distributions, archaeological sites, and environmental data indicates that modern tree communities in Amazonia are structured to an important extent by a long history of plant domestication by Amazonian peoples. Expand
