Lepidoptera in Sudetes Mts.: effect of area and isolation
#Figure 2 and Figure 3 approximately here#
Habitat similarities (Fig. 2) depict two main groups of alpine sites, i.e., the
Krkonose Mts. and the Hruby Jesenik Mts. An unstable and not much robust linkage
shows the Kralicky Sneznik Mts. (AU < 95 within all conducted analysis). The
Kralicky Sneznik Mts. finds its position in both mentioned clusters, the Krkonose Mts. as
well as the Hruby Jesenik Mts., depending on the clustering method. The Krkonose Mts.
cluster is very constant (AU = 100) and species composition of included alpine sites is
almost identical. The Hruby Jesenik Mts. cluster is composed of two compact groups of
alpine sites (AU = 96). The first one contains larger and geographically close sites with
characteristic species for the Hruby Jesenik Mts. and the second one represents smaller
and rather isolated sites with non-specific and little diversified fauna characteristic for the
entire region of the High Sudetes Mts.
Our diagnostic species pool splits similarly to what is mentioned above
(Fig. 3). A compact group of species with a specific affinity for the Hruby Jesenik
Mts. is clearly distinguished here (AU = 97): Sparganothis rubicundana, Clepsis
steineriana, Erebia epiphron, Catoptria petrificella, Clepsis rogana and Erebia sudetica.
These species are primarily present in the central treeless zone of the Hruby Jesenik Mts.
consisting of following alpine sites: Praded, Maly Ded and Vysoka hole. This central
zone represents a “core” of relict mountain species in the Hruby Jesenik Mts. Next cluster
represents species preferentially connected with the Krkonose Mts. (see the compact
groups of Elophos operarius, Olethreutes obsoletanus, Xestia alpicola; AU = 100;
Psodos quadrifarius, Catoptria maculalis,... AU = 100) and distributed within the entire
