Four species of Fenestrida and two species of Rhabdomesida occur in the Otter Formation (Viséan) of the Little Belt Mountains, central Montana. Four species are new: Laxifenestella snyderi n. sp., Rectifenestella concava n. sp., Streblotrypa (Streblascopora) eastoni n. sp., and Nikiforovella beltensis n. sp. Several of these species are very similar to species described in Viséan rocks of central Mongolia, northeast Russia, Kazakhstan, and Japan. Fabifenestella cf. F. vulgaris compares closely with F. vulgaris Gorjunova and Morozova from the Lower Carboniferous of northern Mongolia. Most of the bryozoans in the Otter Formation occur in the normal marine, subtidal carbonate mud and calcareous shale microfacies.

AbstractThe Lower Carboniferous, probably Tournaisian, Kweekvlei Formation is part of the Witteberg Group (Cape Supergroup) of South Africa. Together with the overlying Floriskraal Formation, it forms an upward-coarsening succession within the Lake Mentz Subgroup. Sedimentary features of the Kweekvlei Formation suggest deposition in a storm-wave dominated marine setting, within the storm-influenced, distal part of an offshore transition zone environment. This predominantly argillaceous formation preserves a low diversity trace fossil assemblage. Reworked vascular plant debris (including the problematic genus Praeramunculus sp.) and a shark spine have been reported for the Kweekvlei Formation. There are no known stratigraphic equivalents in South Africa.

AbstractThe increasing animosity towards wolves (Canislupus) by livestock-keeping nomads in Mongolia and the accompanying conflicts highlight the urgent need for knowledge about the feeding behavior of wolves, since information on the feeding ecology of wolves in Mongolia is rare, especially in the mountain taiga and mountain forest steppe regions of Northern Mongolia. Those regions are characterized by a relatively high wildlife diversity and are sparsely populated by humans. To face this problem, 137 wolf scats were collected in the Khentii Mountain range in Northern Mongolia between 2008 and 2012. Almost all wolf faeces contained remnants of wild ungulates, which made up 89% of the consumed biomass. Siberian roe deer (Capreoluspygargus) was the most important and positively selected prey species. It was followed by red deer (Cervuselaphus) and wild boar (Susscrofa), which was negatively selected by wolves. Wolves also fed on buffer prey species such as lagomorphs and small mammals. No evidence of domestic ungulates was found in the wolf diet. Thus, near-natural habitats with a diverse fauna of wild animals are important to limit livestock depredation.
