Fig. 6. The relationship between GME and the number of species with marginal climatic niche conditions as of the years 2041–2070.

a, All Category II monitoring as an indicator of effort at the national level. b, Programmes to monitor genetic diversity in selected amphibian, avian, carnivoran and plant species only. Countries are indicated by postal codes. Marginal species include all species chosen for the calculation of marginality, including non-troglobite amphibians, a collection of large birds, selected large carnivorans and a set of forest trees. No general linear trends exist, although there is substantial variation both in numbers of species in marginal niche situations and in GME of countries.
