New Dataset: Biogeographic distribution of the Antarctic and Sub-Antarctic brachiopods (living forms)
The only Antarctic review about brachiopods has been done by Forster in 1974. Since about 100 publications dealing with living Antarctic brachiopods have been issued and nearly 50 on fossil Antarctic brachiopods, until 2009. The classification of the Brachiopoda has been basically changed in 1996 and developed in the 6 volumes of the “Treatise” (1997-2007). … Continue reading New Dataset: Biogeographic distribution of the Antarctic and Sub-Antarctic brachiopods (living forms)
New Dataset: In situ observations of Stygiomedusa gigantea
This dataset was provided by Dhugal Lindsay (Japan Agency for Marine-Earth Science and Technology (JAMSTEC)). The data is extracted from a paper by Mark C. Benfield (Department of Oceanography and Coastal Sciences, Louisiana State University) and William M. Graham (Dauphin Island Sea Lab and University of South Alabama). Four individuals of the large scyphozoan jellyfish … Continue reading New Dataset: In situ observations of Stygiomedusa gigantea
New dataset: SO-Polylist
The dataset contains over 6200 single records covering approx 95% of all literature available on Antarctic Polychaeta including the famous monographs of Olga Hartman. Additionally new records from the expeditions ANDEEP I-III and ANDEEP-Systco have been added.
New Dataset: Penguins of Antarctica
Classic problems in historical biogeography are where did penguins originate, and why are such mobile birds restricted to the Southern Hemisphere? Competing hypotheses posit they arose in tropical–warm temperate waters, species-diverse cool temperate regions, or in Gondwanaland less than 100 mya when it was further north. To test these hypotheses we constructed a strongly supported … Continue reading New Dataset: Penguins of Antarctica
New Dataset: Antarctic Isopods
The phylogenetic relationships of 14 species of the Antarctic amphipod families Epimeriidae and Iphimediidae were investigated using 553 bp of the gene for the mitochondrial cytochrome oxidase subunit I (COI) and 98 morphological characters. Both families are dominant members of the Antarctic benthic amphipod community. In contrast to previous studies, our molecular and morphological data … Continue reading New Dataset: Antarctic Isopods
New Dataset: Antarctic Pycnogonids II
Colossendeis megalonyx Hoek, 1881 is a widespread and abundant pycnogonid in the Southern Ocean which has also been reported from the South Atlantic and South Pacific Oceans. Its strictly benthic lifestyle is expected to promote genetic differentiation among populations and ultimately facilitate speciation. On the other hand, the reported eurybathy and unknown larval stages of … Continue reading New Dataset: Antarctic Pycnogonids II
