Possibly discoveries of local bird and primate endemics have been made by specialists that would not recognise interesting forms outside their speciality, so that the presence of concentrations of endemic taxa of primate in certain areas might be a good basis for selecting priority areas for taxonomic research on birds, and vice versa. Different responses to biogeographical changes (climate) It appears that much of the recent biogeography of Madagascar has been dominated by climate change (Goodman & Rakotozafy 1997), which has produced forest "bridges" across the variably wooded central plateau during interglacial periods. Some of these bridges are shown in Western and southern bird communities are probably largely derived from invasions of eastern founders across these bridges, and several local western and southern endemics {Bernieria [=Phyllastrephus] apperti, Monticola bensoni, Monticola erythronotus, Monticola imerinus, Calicalicus rufocarpalis, Newtonia archboldi) are probably recent splits from eastern montane species. Only Uratelornis chimaera, Monias benschi, and Mesitornis variegata seem to be ancient endemic inhabitants of the west, and even M. variegata has also recently been discovered in the east (Thompson & Evans 1992), confusing the question of its origin. The pattern of recent western invasion is shown also in certain carnivores (Galidia, Galidicitis, Eupleres) and at least one rodent (Nesomys), two subspecies of the generalist Brown lemur (Eulemur fulvus rufus and fulvus), and the.
