Dispersal patterns of endemic alpine butterflies with contrasting population structures: Erebia epiphron and E-sudetica.

Popis výsledku v původním jazyce

We studied population sizes and mobility of Erebia epiphron and Erebia sudetica, two high mountain butterflies forming endemic subspecies in the Hruby Jesenik Mountains, Czech Republic. E. epiphron formed two continuous populations containing approximateto100,000 and approximate to4,500 individuals on alpine grasslands. The butterflies moved freely within their habitats, but movements between the two populations were highly unlikely. E. sudetica formed a system of colonies at timberline sites on valleyheadwalls and in forest clearings. Two such colonies studied in detail contained approximate to4,500 and approximate to450 adults and were interconnected by limited dispersal. The negative exponential function and the sigmoid function (this assumes flatdecrease of movements over short distances) were superior to the inverse power function in fitting mobility data for both species. For E. sudetica, the functions describing movements within a habitat differed significantly from total mov
