Patagonian “Diprotodont” Mammals 1

Checklist of helminths found in Patagonian wild mammals.

Using available reports, a checklist of the recorded helminth parasites of wild mammals from Patagonia was generated. Records of parasites found in Patagonia were included, together with records from mammals in áreas outside of Patagonia but whose range extends into Patagonia. Information about the host, localities, and references were also included. A total of 1323 records (224 Cestoda, 167 Tr...

The Impact of Predation by Marine Mammals on Patagonian Toothfish Longline Fisheries

Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss. Depredation can also create additional unrecorded fishing mortality of a stock and has the potential to introduce bias to stock assessments. Here we aim to characterise depredation in the Patagonian ...

Patagonian Ethnogenesis: towards a computational simulation approach

The basis of this research project is the computer simulation of the emergence of ethnicity and cultural differentiation in prehistoric hunter-gatherer groups. Instead of working directly on a universal theoretical model, we have preferred a predictive simulation of a historical case (ancient Patagonia) where the knowledge about the simulated social system is available at the necessary level of...

An Overview of Sex Selection at Conception in Mammals

Although the mechanisms under which sex ratio is controlled in nature remain unknown, researchers have attempted to treat sperm in an effort to predetermine the sex of the offspring. The methods of sperm separation that have been repeatedly reported to isolate fractions rich in X- or Y-chromosome bearing sperm are serum albumin gradient swim-up and flow cytometry. However, the ability of the se...
