Divergence between passerine populations from the Malvinas - Falkland Islands and their continental counterparts: A comparative phylogeographical study
(Wiley Blackwell Publishing, Inc, 2012-08)
Bursts of speciation have followed colonization of remote oceanic islands by diverse taxa, a process evidenced by island endemics around the world. The present study explores whether the Malvinas - Falkland Islands (MFI), ...

A micropaleontological analysis of foraminifera and palynomorphs obtained from a partial sedimentary section cropping out at Ekelöf Point, eastern James Ross Island, Antarctic Peninsula, is presented. The section, named ...
General ecology of coastal fish from the South Shetland Island and west Antarctic Peninsula areas
(Alfred Wegener Institut für Polar und Meeresforschung, 2008-10)
There is a lower diversity of Antarctic fish species on the continental shelves (139 spp) compared with other cold-water seas (> 350 spp in the North Atlantic). However, although the diversity of the notothenioids is limited ...
