Estimating numbers of whales present in an area from recorded call rates could be a useful conservation
tool. We recorded southern right whale Eubalaena australis vocalisations and presence in Walker
Bay on the south ...

Formants, the resonance frequencies of the vocal tract, are the key acoustic parameters underlying vowel
identity in human speech. However, recent work on nonhuman animal communication systems has
shown that formant ...

Describing the repertoire of sounds produced by wild cetaceans is necessary for understanding their
function, for acoustic population monitoring and for measuring the potential influence of
anthropogenic impact. Geographic ...

Large carnivores are important ecosystem components but frequently suffer local extinctions. However, reintroductions and shifting
conservation attitudes have lead to some population repatriations. Since the ecological ...

Life history theory predicts a change in reproduction success with age as energy
resources are limited and must be allocated effectively to maximise reproduction and
survival. In this study we use three reproductive ...

The social organization of giraffes (Giraffa camelopardalis) imposes a high-cost
reproductive strategy on bulls, which adopt a ‘roving male’ tactic. Our observations on
wild giraffes confirm that bulls indeed have ...
