Resource depletion and colonization: a comparison between parthenogenetic and sexual Collembola species.

摘要: Summary Sexual reproduction is the common mode of in Collembola but several species reproduce by parthenogenesis. Both reproductive modes have advantages and disadvantages. Usually, under resource-limited conditions sexual are dominant, whereas parthenogenetic prevail stable habitats. In order to investigate if affected differently environmental we established two experiments. first experiment laboratory microcosms with declining resources were effect resource depletion on density species. For second experiment, defaunated heat inoculated fresh soil or litter material recolonization We hypothesized that more sensitive compared species, they will colonize available habitats faster due their reproduction. Contrary our hypothesis, similarly depletion. agreement proportion increased time when free plenty available, indicating fact colonizers.
