Chorotypes as a tool for distribution pattern assessment

Popis výsledku v původním jazyce

Concept of ?chorotype? was originally defined by Baroni-Urbani et al. (1978) as an elementary distribution pattern followed by one or several species that can be operatively recognized within a territory. In other words, chorotype can be defined as the group of species whose distribution in space overlap more than expected at random. Real et al. (1992) developed a probabilistic method for testing the existence of such groups of species starting from classification analysis of species according to theirgeographical distribution. We applied this method on distribution data of native small mammals (Insectivora, Rodentia) of the Czech Republic. Data were extracted from distribution atlases based on a grid of 679 cells, each of them represents 11,1 x 12 kmlarge area. Analyses led to four multispecies chorotypes. Three of them are geographically more or less restricted, and one chorotype is widespread. The first chorotype includes mainly steppe species (e.g.
