This chapter is based on ecological information on 82 radio-tagged badgers (39 F, 43 M) among three study populations in British Columbia, Canada between 1996 and 2010, data that were collected to learn more about the ecology of badgers and consider how variation in their ecology might inform regional conservation strategies. The widely spaced, lower density prey and distribution of soil deposits suitable for digging in British Columbia likely required badgers to use substantially larger areas, relative to the core range, in which to acquire sufficient energy to survive and reproduce. Strikes from automobiles were the primary cause of death among all radio-tagged badgers and this source of mortality is pervasive throughout the limited distribution of badgers in British Columbia. Despite their potential for high fecundity, populations of badgers in British Columbia likely remain at considerable risk compared to those in the core of the species’ range.

Occurrence Records

Abstract Knowledge about the current distribution of threatened and/or understudied species is a fundamental component of conservation biology. Mapping species distributions based on recent known occurrences is particularly important for those that are rare or declining. Too often, cryptic species go undetected throughout parts of their range, whereas others just receive less research attention. We used contemporary presence data for the Pallas’s cat (Otocolobus manul), a small cryptic felid, to characterize potential rangewide and regional habitat for the species and identify those abiotic and biotic variables most influencing its distribution. Several regions lacking contemporary occurrence records contain potential habitat for Pallas’s cats, including the Koh-i-Baba Mountains of Afghanistan, Qinghai-Tibetan Plateau, steppes of Inner Mongolia, Kunlun Mountains of China, and Tian Shan and Pamir Mountains of Kyrgyzstan, Tajikistan, and China. Some of these areas have not been included in prior rangewide distribution assessments. The distribution of pikas (Ochotona spp.), small mammals that likely represent a critical prey species everywhere they are sympatric, was the most important factor affecting the Pallas’s cat’s distribution. This suggests Pallas’s cats may be prey specialists, and that pika presence and habitat are critical considerations for future Pallas’s cat surveys and in the development of regional conservation actions.

The economic and socio-political interactions between countries can have major impacts on transboundary conservation decisions and outcomes. Here, we examined for 14 Western Indian Ocean (WIO) continental and island nations the extent of their marine coral reef species, fisheries and marine protected areas (MPAs), in the context of their geopolitical and socio-economic connections. We also examined the role of external countries and organisations in collaboration within the region. We found large variation between the different countries in their protected area size, and management, which result from different interests in establishing the MPAs, ranging from fisheries management, biodiversity conservation to asserting sovereignty claims. Seventy-four per cent of the 154 MPAs in the region belong to island nations; however, the largest MPAs in the WIO were established by European powers, and include Mayotte and Glorioso Islands (France) and Chagos (UK). While the majority of MPAs are managed by individual countries, between-country collaboration within and outside the region is key if the aim is to achieve effective conservation of ecosystems and species across the island and mainland nations in the region. This may be advanced by creating transboundary MPAs and by regional conservation investment by external powers that benefit from the region’s resources.
