Abstract The Belo Monte hydroelectric dam on the Xingu River has third largest generating capacity of any in world. We conducted surveys crocodilians ( Caiman crocodilus , Paleosuchus trigonatus ) by boat at site prior to (2013-2015), and after filling (2016-2017). While number C. sighted decreased with increasing water level, there was no difference numbers to, reservoir filling. P. unaffected...

Domestic political and economic instability provides a window of opportunity for external military intervention. To examine the factors that underlie the strategic decisions to pursue military intervention in the presence of instability, I develop a game-theoretic model in which two external powers sequentially decide whether to intervene militarily in a third country. The level of domestic ins...

From October 1986 to January 1987, feces from 119 Caiman yacare and 12 Caiman latirostris were collected in Paraguay and later examined for coccidian oocysts; 69 of 119 (58%) samples from C. yacare and 3 of 12 (25%) samples from C. latirostris contained coccidian oocysts. Two eimerians infected C. yacare and both are described as new species. Sporulated oocysts of Eimeria paraguayensis n. sp. a...

The saltwater crocodile is the largest of all living reptiles. It is also known and proved that it has the largest biting forces. The magnitude of the biting force exerted by the jaw leads to thoughts about the anatomical structure and construction of the jaw joint in this reptile. Thirteen skulls of the saltwater crocodile (C. porosus) were used for this study. Some skulls were used for X-rayi...

Purussaurus brasiliensis thrived in the northwestern portion of South America during the Late Miocene. Although substantial material has been recovered since its early discovery, this fossil crocodilian can still be considered as very poorly understood. In the present work, we used regression equations based on modern crocodilians to present novel details about the morphometry, bite-force and p...
