Prey patch patterns predict habitat use by top marine predators with diverse foraging strategies. [PDF]

PLoS ONE, 2013
Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring ...

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The eared seals (family Otariidae) are divided into fur seals and sea lions, despite a lack of cladistic support for these groups. The division is primarily based on hair morphology, and it is unknown whether any other morphological signal differentiates these two groups.
