Soil salinity determines the diversity of snail-killing flies (Diptera: Sciomyzidae) in brackish marshes

Brackish marshes resulting from embankments are a rare habitat in Europe and for which there is little knowledge of the entomofauna. There is an urgent need to document the insect diversity and its unique properties in the light of ongoing habitat losses. The current study focuses on snail-killing flies in the remaining Belgian brackish marshes, in particular the role of soil salinity in determining their diversity and how it compares with that in freshwater marshes. Snail-killing fly communities in brackish marshland were relatively species poor and clearly different from those in freshwater,... Mehr ...
