Projecting terrestrial biodiversity intactness with GLOBIO 4

Assessing biodiversity intactness at multiple scales

The Southern Africa Millennium Ecosystem Assessment developed an index for quantifying the state of biodiversity. The Biodiversity Intactness Index (BII) operates at the species level, and is based on changes in species abundance, rather than changes in richness brought about by extinction. The BII uses spatial data on species richness and land use activities per ecosystem type to weight estima...

Estimating terrestrial biodiversity through extrapolation.

Both the magnitude and the urgency of the task of assessing global biodiversity require that we make the most of what we know through the use of estimation and extrapolation. Likewise, future biodiversity inventories need to be designed around the use of effective sampling and estimation procedures, especially for 'hyperdiverse' groups of terrestrial organisms, such as arthropods, nematodes, fu...

Terrestrial Insects: A Hidden Biodiversity Crisis?

Like most other elements of the biota, the terrestrial insect fauna of Illinois has undergone drastic change since European colonization of the state. Although data are sparse or entirely lacking for most species, it is clear that many formerly abundant native species are now exceedingly rare while a few previously uncommon or undocumented species, both native and exotic, are now abundant. Much...
