Distribution of two notodendrodid foraminiferal congeners in McMurdo Sound, Antarctica: an example of extreme regional endemism?
We used morphological and molecular surveys to determine the presence or absence of Notodendrodes antarctikos and its congener, Notodendrodes hyalinosphaira, at diverse sites within McMurdo Sound, Antarctica. Morphological surveys were performed using shipboard box-core sampling, as well as handheld...
