| Abstract | Carabid and cicindelid beetles belong to the most diverse group of insects in the world and in Flanders. Typical coastal dune species are mainly restricted to sandy and dynamic habitats [marram dunes, pioneer dune slacks], xerothermic grasslands and moss-dominated dunes. Typical species for salt marshes in our region also occur along the coast. A total of 65 ground and tiger beetle species can therefore be defined as typical for the Flemish maritime region. Of these, more than one third declined significantly, while only two species showed a While on a larger scale, it results in strong genetic differentiation of isolated dune and salt marsh beetle populations. Recent increase in occurrence. We are also conducting long term studies on diversity, population dynamics and ecological and genetic effects of habitat fragmentation on carabid beetles in coastal dunes and salt marshes. Apparently a high year-to-year species turnover exists in the coastal dunes, in which about half of the species can be categorized as migrants. Typical species remain present, although their population density shows strong fluctuations between years. Habitat fragmentation encourages the invasion of non-typical species. |
