The introduced yellow crazy ant or long-legged ant Anoplolepis gracilipes was first reported in Seychelles in 1969 and now occurs on at least nine islands in the Central Seychelles. We describe the yellow crazy ant's effects on vegetation and invertebrate communities on one of these, Bird Island; in 2000, Anoplolepis (first reported in 1991) occurred there(More)
Long-term persistence of species characterized by a reduced effective population size is still a matter of debate that would benefit from the description of new relevant biological models. The island endemic specialist Drosophila sechellia has received considerable attention in evolutionary genetic studies. On the basis of the analysis of a limited number(More)
Although they are conspicuous components of the native fauna, the orthopteroid insects of the Seychelles islands have attracted little attention from ecologists and conservationists throughout most of the twentieth century. Yet, at a complex crossroads, where the Afro-tropical, Malagasy and Oriental faunal regions overlap, they are potentially valuable(More)
The Seychelles archipelago is characterized by an exceptionally high level of endemism in certain taxa, including at least 275 endemic species of Lepidoptera (Legrand 1966; Gerlach & Matyot 2006; De Prins & De Prins 2015). Despite the fact that endemics are the main objects of conservation efforts, information regarding endemic Seychelles Lepidoptera is(More)
