Problem solving and tool use in three species of otter
Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis …

NORTHERN RIVER OTTER POPULATION ASSESSMENT AND CONNECTIVITY IN WESTERN MONTANA
Northern river otters (Lontra canadensis) are elusive and difficult to monitor, and little is known about their movement patterns or how populations are structured on the landscape. Otters are sensitive to degradation of aquatic systems, mostly due to loss of prey. This is evident in the Upper …

The analysis of cryptographic APIs using the theorem prover Otter
… for analysis using a theorem prover known as OTTER. These implementations successfully found known attacks, and provide evidence that OTTER will also be able to find new attacks, and perhaps eventually verify security in arbitrary Cryptographic APIs. Based on these implementations, various …

Geology of the Peaks of Otter area, Bedford and Botetourt counties, Virginia
The Peaks of Otter area includes two-thirds of the fifteen-minute Peaks of Otter quadrangle in the Blue Ridge and Piedmont physiographic provinces of central Virginia. The rocks of the area are mainly early Precambrian igneous, metasedimentary, and meta-igneous formations, which are cut by small …

Conservation ecology of the Cape clawless otter, Aonyx capensis, in an urban environment
… and pollution. Globally, it has been found that otter's dependence on these ecosystems exposes them to a myriad of threats, including loss of habitat, human-wildlife conflict and the bioaccumulation of toxic pollutants. The Cape clawless otter, Aonyx capensis, is the most widely distributed otter …

THE STATUS OF OTTERS (CARNIVORA : MUSTELIDAE : LUTRINAE) IN SINGAPORE AND MALAYSIA, AND THE DIET OF THE SMOOTH OTTER (LUTROGALE PERSPICILLATA) IN PENANG, WEST MALAYSIA
The IUCN/SSC Action Plan for Otters (Foster-Turley et al., 1990) alerted the scientific community to the fact that the biology of otters is relatively unknown, particularly in Asia. In response to this plan, the conservation biology of otters in Singapore and Malaysia is herein addressed. Three …
