TL;DR: A consistent positive concave-down effect of biodiversity on forest productivity across the world is revealed, showing that a continued biodiversity loss would result in an accelerating decline in forest productivity worldwide.

TL;DR: In this article, the authors examined the abundance and distribution of Sumatran tigers and nine prey species in Bukit Barisan Selatan National Park on Sumatra, Indonesia, and demonstrated that the relative abundance of tigers and their prey, as measured by camera traps, is directly related to independently derived estimates of densities for these species.

TL;DR: It is shown that the number of camera days/tiger photograph correlates with independent estimates of tiger density, a statistic that is particularly useful for estimating the population density of species that are not individually identifiable.

TL;DR: An interdisciplinary perspective on the prospects of satellite remote sensing (SRS) for ecological applications is provided, reviewing established avenues and highlighting new research and technological developments that have a high potential to make a difference in environmental management.
