Population status of the Antarctic shag Phalacrocorax ( atriceps ) bransfieldensis
Abstract Antarctic shags Phalacrocorax ( atriceps ) bransfieldensis are the southernmost cormorants in the world and assessment of their conservation status has been complicated by the logistical challenges of obtaining regular estimates of population size, as well as by taxonomic ambiguity of the b...
