Dogs can discriminate stressed from non-stressed human odour samples, but the effect on
their cognition is unstudied. Using a cognitive bias task, we tested how human odours affect …

Our natural body odor goes through several stages of age-dependent changes in chemical
composition as we grow older. Similar changes have been reported for several animal …

Despite its recent invasion into the marine realm, the sea otter (Enhydra lutris) has evolved a
suite of adaptations for life in cold coastal waters, including limb modifications and dense …

The fermentation hypothesis for animal signalling posits that bacteria dwelling in an animal's
scent glands metabolize the glands' primary products into odorous compounds used by the …

Numerous terrestrial mammal species have experienced extensive population declines
during past centuries, due largely to anthropogenic pressures. For some species, including …

Mammals commonly communicate olfactorily via urine. However, the extent to which they
communicate via dung, another waste product, is unknown. Behavioural studies suggest …

Growing human-wildlife conflicts and legal conservation obligations increased the need for
precise information on Eurasian otter (Lutra lutra) population parameters for species status …

Quantifying population status is a key objective in many ecological studies, but is often
difficult to achieve for cryptic or elusive species. Here, non-invasive genetic capture-mark …

The use of conservation dogs is rapidly increasing. These canine units are usually
employed to discriminate target species odor from nontarget ones to monitor or aid in the …

Toxic metals have been linked to a range of adverse health effects in freshwater organisms.
However, for higher vertebrates, there is little understanding of the large-scale drivers of …
