TL;DR: The results show that, whereas the biodiversity indicator group concept may hold some validity for several taxa that are frequently sampled, it fails for those exhibiting highly idiosyncratic responses to tropical land-use change, highlighting the problems associated with quantifying the biodiversity value of anthropogenic habitats.

TL;DR: Estimated global-warming-induced rates of species extinctions in tropical hotspots in some cases exceeded those due to deforestation, supporting suggestions that global warming is one of the most serious threats to the planet's biodiversity.

TL;DR: Positive and significant correlations between matrix abundance and vulnerability to fragmentation are exhibited, suggesting that species that avoid the matrix tend to decline or disappear in fragments, while those that tolerate or exploit the matrix often remain stable or increase.

TL;DR: This work presents a generic and novel framework for identifying high-performance indicator taxa that combine practical feasibility and ecological value, and illustrates the approach using a large-scale assessment of 14 different higher taxa across three forest types in the Brazilian Amazon.
