Extinction risk from climate change
TLDR
Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
Agricultural intensification and the collapse of Europe's farmland bird populations
TLDR
The results suggest that recent trends in agriculture have had deleterious and measurable effects on bird populations on a continental scale and predict that the introduction of EU agricultural policies into former communist countries hoping to accede to the EU in the near future will result in significant declines in the important bird populations there.
Farming and the Fate of Wild Nature
TLDR
It is shown that the best type of farming for species persistence depends on the demand for agricultural products and on how the population densities of different species on farmland change with agricultural yield, and that high-yield farming may allow more species to persist.
Reconciling Food Production and Biodiversity Conservation: Land Sharing and Land Sparing Compared
TLDR
Compared crop yields and densities of bird and tree species across gradients of agricultural intensity in southwest Ghana and northern India, land sparing is a more promising strategy for minimizing negative impacts of food production, at both current and anticipated future levels of production.
Economic Reasons for Conserving Wild Nature
TLDR
It is estimated that the overall benefit:cost ratio of an effective global program for the conservation of remaining wild nature is at least 100:1.
The Living Planet Index: using species population time series to track trends in biodiversity

TLDR
The two methods of calculating the Living Planet Index show very similar results: terrestrial species declined on average by 25% from 1970 to 2000 and it may be possible to reduce this further by post-stratification and weighting, but new information would first need to be collected for data-poor classes, realms and biomes.
Monitoring change in biodiversity through composite indices
TLDR
It is concluded that no single index can capture all aspects of biodiversity change, but that a modified Shannon index and the geometric mean of relative abundance have useful properties.
Diclofenac poisoning as a cause of vulture population declines across the Indian subcontinent
TLDR
It is recommended that urgent action is taken in the range states of the three currently threatened vulture species to prevent the exposure of vultures to livestock carcasses contaminated with diclofenac.
Global mapping of ecosystem services and conservation priorities
TLDR
The preliminary results show that regions selected to maximize biodiversity provide no more ecosystem services than regions chosen randomly, and spatial concordance among different services, and between ecosystem services and established conservation priorities, varies widely.
