The main purpose
of the work
was to test
the applicability of bioclimatic modeling methods to mosses. Due
to tiny size
bryophyta are confined to micro-habitats,
which can transmute the influence
of climatic factors. Crossidium squamiferum was taken as test
object. Potentially suitable climatic area of the
species in the world was simulated using
maximum entropy (MaxEnt) modeling on base of
four datasets different in volume
(from 24 to 267 points). All the
models are characterized by valid AUC values (from
AUC=0.72 to AUC=0.96). According to the calculations,
the most important variables determining the distribution of C. squamiferum are BIO4 (Temperature seasonality) and BIO8 (mean temperature
of the wettest
quarter). Habitats of the species
in southern Siberia mark the
Northern climatic boundary of the
species area in Eurasia.
