Tracking the decline of the once-common butterfly: delayed oviposition, demography and population genetics in the hermit Chazara briseis

Original language description

Large populations, seemingly not at risk of extinction, can decline rapidly due to alteration of habitat. This appears to be the case of the butterfly Chazara briseis, which is declining in all of Central and Eastern Europe, even from apparently large areas of its steppe grassland habitats. We combined mark-recapture, allozyme electrophoresis and adult behaviour observation to study the last remaining metapopulation of this once-widespread butterfly in the Czech Republic. The total population estimate was 1300 males and 1050 females in 10 colonies within a 70 km2 landscape. Adults were long-lived, and inseminated females required several weeks before they started ovipositing. Models using realistic lengths of the preoviposition period estimated that due to background mortality, only 25-55% of the female census population lived long enough to contribute to the next generation. This demographic load was unlikely to be balanced by an increased fecundity.
