Temporal segregation in the surface community of an ephemeral habitat: Time separates the potential competitors of coprophilous Diptera

Popis výsledku v původním jazyce

Temporal separations among species greatly enhance the species’ coexistence, especially in insect communities inhabiting temporally unstable, yet resource-rich ephemeral habitats like dung or carrion. The insect communities inhabiting ephemeral habitats consist of two components, the internal community, dwelling within the substrate (mostly Coleoptera), and the surface community, inhabiting the habitat’s outer rim (mostly adult Diptera). In contrast to the internal community, the surface community is very rarely studied. We present here the first quantitative study of temporal trends in the surface community of coprophilous dipteran adults. Using artificially created 1.5 l cow dung pats, we studied the succession and seasonality in the surface community during six sampling periods in 2011 and 2012. In total, we sampled 13,579 adults of dung-visiting Diptera. Both the abundance and species’ richness decreased rapidly throughout the succession, and were highest during the summer season. The community itself was separated into two main (early and late) and four subgroups along the successional gradient; grouping species occurring during the first few hours only (mainly Calyptratae Diptera), species occurring between the first and second day and species occurring between second and third day (mainly Acalyptratae Diptera), and species with optima after third day of dung pat existence (mainly Nematocera). The very early and very late successional groups, occurring during spring-autumn, were seasonally separated from the mid-successional groups, occurring during summer. The ecologically similar species displayed detectable seasonal micro-optima, which likely facilitate their coexistence. There was a high overall similarity in temporal patterns between dung and carrion surface communities.
