Sažetak
Species that inhabit a range of environments often display divergent morphologies between the populations that correlate with differences in ecological parameters. Flood is a strong temporary disturbance of terrestrial environment which could occur on regular frequency or occasionally, that has been shown to influence species composition and function of an ecosystem. On flooded areas, species with better dispersal abilities can migrate when environment become unfavourable. Since the forest ecosystem are inhabited mainly by non flying carabids, the aim of this study was focused on non flying Carabus ulrichii species, abundant in regularly flooded forests in Varoški Lug area and non- flooded forests in Mt. Medvednica and the influence of flood events on some morphology features for males and females. We have compared morphometric data between populations collected from two types of habitats (regularly flooded lowland forests in Varoški Lug and mountain forests in Mt. Medvednica). For both sexes, the body size showed significant differences between lowland and mountain forests, with smaller body sizes measured for individuals from flooded areas. In general, the most prominent pattern for both sexes was lower ratio of femur length vs. body length of individuals from flooded forests. Reduction of mandible and abdomen length was in the same proportion to body size reduction in populations from flooded and non flooded forests. Due to flood events and migration activities, body size reduced as energy trade-off, trying to keep fertility, dispersal and foraging abilities at the highest level. These results provide empirical evidence for an adaptive benefit of the observed shape change.
