Biophysical Field Methods Gobabeb, 2016

Gobabeb Poster 3

In March 2016, a group of students from the USA, Israel, Namibia and South Africa met at the Gobabeb Desert Research and Training Centre, in the Namib Desert of Namibia for an intensive ten-day field research experience in desert ecology. They came to Gobabeb as part of a hybrid online/field course called Biophysical Field Methods, taught by Profs Scott Turner (SUNY ESF), Berry Pinshow (Ben-Gurion University) and Dr Eugene Marais, National Museum of Namibia. This is the story of that group. Produced by Tiffany Deater.







Biophysical Field Methods Online Course, 2015 – 2016

Biophysical field methods online offers a practical approach to biophysical ecology, which applies physical concepts, principles and techniques to the interpretation of animal-environment interactions. These include how physical laws, such as the laws of thermodynamics, affect the abundance and distribution of animals and plants, the nature of microclimate, the ecological niche, and the integration of physiology and evolutionary ecology. Biophysical Field Methods Online








Ducks, Geese, and Swans of North America, 2015

Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent’s forty-six species. Maps of both winter and breeding ranges are presented with stunning images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines.

Divergence and Degradation of a Supergene/ Curr. Biol., Jan. 21, 2015 (Vol. 26, Issue 3)

Morphs of the white-throated sparrow are determined by large alternative supergenes located on an inversion of chromosome 2. Using over two decades of field data, Tuttle et al. document near-perfect disassortative mating and fitness consequences for those birds that pair assortatively. They then used de novo whole-genome sequencing coupled with population- and phylo-genomic data to show that white and tan morphs are highly divergent at over 1,000 genes, that both supergenes originated prior to the split of the white-throated sparrow from its sister species, and that the white morph supergene was introduced into the lineage through past hybridization/introgression and is degrading over time. The results show how supergenes can arise and become polymorphic in a single species and how, despite their apparent stability in the short term, they are likely to be unstable over long evolutionary time periods.
