TL;DR: Most indicators of the state of biodiversity showed declines, with no significant recent reductions in rate, whereas indicators of pressures on biodiversity showed increases, indicating that the Convention on Biological Diversity’s 2010 targets have not been met.

TL;DR: With the first plenary meeting of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) soon under way, partners are developing—and seeking consensus around—Essential Biod diversity Variables (EBVs) that could form the basis of monitoring programs worldwide.

TL;DR: A comprehensive mid-term assessment of progress toward 20 biodiversity-related “Aichi Targets” to be achieved within a decade is provided using 55 indicator data sets and pinpoints the problems and areas that will need the most attention in the next few years.
Journal ArticleDOI
Developing indicators for European birds
Richard D. Gregory,Arco J. van Strien,Petr Vorisek,Adriaan W. Gmelig Meyling,David G. Noble,Ruud P. B. Foppen,David W. Gibbons +6 more
TL;DR: It is argued that the farmland bird indicator is a useful surrogate for trends in other elements of biodiversity in this habitat, and developed statistical methods to calculate supranational, multi-species indices using population data from national annual breeding bird surveys in Europe.
Journal ArticleDOI
Patterns of natal and breeding dispersal in birds
Emmanuel Paradis,Emmanuel Paradis,Stephen R. Baillie,William J. Sutherland,Richard D. Gregory +4 more
TL;DR: A significant positive relation was observed between breeding dispersal distance and long-term population decline among migrants, but not among residents, suggesting that this habitat variable does not impose the same constraint on natal dispersal.
