Figure 5.1
Share of species of three aquatic insect groups, caddisflies (Trichoptera),
stoneflies (Plecoptera) and mayflies (Ephemeroptera), potentially endangered by climate
change in selected European ecoregions according to Illies (1978) (two Northern
European ecoregions, two Central European ecoregions, two Mediterranean ecoregions
and two high mountain areas). Data based on 1134 Trichoptera taxa, 563 Plecoptera
taxa and 344 Ephemeroptera taxa.
was used to calculate the fraction of species in each of the above groups. The data
are based on an intensive literature survey and cover all European taxa of the
selected organism groups (see Graf
et al.
(2008) for Trichoptera, Graf
et al
. (2009)
for Plecoptera and Buffagni
et al
. (2009) for Ephemeroptera).
For all three orders, a high proportion of species in the Mediterranean
ecoregions and in high mountain areas are highly vulnerable to climate change
(Fig. 5.1). Most Central and Northern European species, however, are widely
distributed and likely to be less affected by climate change.
