Estimating diet composition from scat analysis in otariid seals (Otariidae): is it reliable? [PDF]

open access: yesCanadian Journal of Zoology, 1988
Analysis of teleost sagittal otoliths contained in scats has been widely used to determine the diet of seals. This method is based on the assumption that relative frequencies of otoliths in scats faithfully reflect those offish in the diet. This assumption has rarely been tested experimentally.

Most mammals do not wander: few species escape continental endemism

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Terrestrial mammals are found nearly everywhere on Earth. Yet, most taxa are endemic to a single continent; geological, evolutionary, ecological, or physiological filters constrain geographic distributions. Here, we synthesize data on geography, taxonomy, lineage age, dispersal, body size, and diet for > 4000 terrestrial mammals prior to detectable ...
