with other cats. Finally, cats need to read and understand human behaviour better (which is where dogs have really excelled). Bradshaw argues that early socialisation and training can help achieve some of these goals, but that we should also consider selective breeding of behaviour. Controversially, the author is suggesting that widespread neutering in the UK be relaxed, arguing that the practi...
متن کاملPatterns of kinship in groups of free-living sperm whales (Physeter macrocephalus) revealed by multiple molecular genetic analyses.
Mature female sperm whales (Physeter macrocephalus) live in socially cohesive groups of 10-30, which include immature animals of both sexes, and within which there is communal care of the young. We examined kinship in such groups using analyses of microsatellite DNA, mitochondrial DNA sequence, and sex-linked markers on samples of sloughed skin collected noninvasively from animals in three grou...
متن کاملArteriovenous patterns in beaked whales
OBJECTIVES The objective of the research thus far was to characterize the gross morphology of the blood vessels in the heads of beaked whales. Description and understanding of this architecture would be accomplished through dissection and diagnostic imaging techniques. Final products would involve peer reviewed publications of resulting data and presentation of findings are the Society for Mari...
متن کاملMolecular genetic identification of southern hemisphere beaked whales (Cetacea: Ziphiidae).
To assist in the species-level identification of stranded and hunted beaked whales, we compiled a database of 'reference' sequences from the mitochondrial DNA control region for 15 of the 20 described ziphiid species. Reference samples for eight species were obtained from stranded animals in New Zealand and South Australia. Sequences for a further seven species were obtained from a previously p...
متن کاملExtreme diving of beaked whales.
Sound-and-orientation recording tags (DTAGs) were used to study 10 beaked whales of two poorly known species, Ziphius cavirostris (Zc) and Mesoplodon densirostris (Md). Acoustic behaviour in the deep foraging dives performed by both species (Zc: 28 dives by seven individuals; Md: 16 dives by three individuals) shows that they hunt by echolocation in deep water between 222 and 1885 m, attempting...
