AbstractNinety‐three papers on home‐range analysis using radio‐tracking data were reviewed; these papers were found in a literature search of 18 of the major journals likely to include such papers, published in the 5‐year period to the end of 1988. The review showed that even 25 years after the first radio‐tracking studies, in the majority of papers there was still...... hiện toàn bộ
ABSTRACTFor any frustrated field‐mammalogists seeking observational data on their elusive study animals, dung may represent the most readily‐available and easily‐collected source of information upon which they may fall back in despair. Yet it is surprising how much ecological information may be deduced from an analysis of faecal depositions. This present article re...... hiện toàn bộ

AbstractDespite conservation concerns for many species of bats, factors causing mortality in bats have not been reviewed since 1970. Here, we review and qualitatively describe trends in the occurrence and apparent causes of multiple mortality events (MMEs) in bats arou...... hiện toàn bộ
AbstractExisting knowledge of the social organization, mating system and reproduction of Humpback Whales (Megaptera novaeangliae) is reviewed to assess how our current understanding of this wide‐ranging marine mammal fits into the predictive framework developed from ecological studies of more accessible terrestrial taxa. The small unstabl...... hiện toàn bộ
AbstractResearch into dolphin swimming has historically been guided by false assumptions of ‘effortless’, ‘high‐speed’ swimming. These assumptions have instigated the development of drag‐reduction hypotheses but tests of these hypotheses have generally had little success. The autecological approach has dominated recent efforts and has been more successful. In this ...... hiện toàn bộ
ABSTRACTOverhunting reduced Eurasian Beaver (Castor fiber) populations to c. 1200 animals, in eight isolated populations, around the end of the 19th century. Protection, natural spread and reintroductions led to a powerful recovery in both range and populations during the 20th century, which continues at a rapid...... hiện toàn bộ
