Visual fields, foraging and collision vulnerability in gulls (Laridae)
Ibis, Volume 167, Issue 2, Page 386-396, April 2025.Wide variation in visual field configuration has been recorded among avian species and it is hypothesized that this variation is driven primarily by foraging ecology and predator detection. It has also been shown that visual field configurations can render some species more vulnerable to collisions with human artefacts that extend into open airspace ...

Medium-sized exotic prey create novel food webs: the case of predators and scavengers consuming lagomorphs [PDF]
, 2016 Food web interactions are key to community structure. The introduction of species can be seen as an uncontrolled experiment of the addition of species. Introduced species lead to multiple changes, frequently threatening the native biodiversity. However,

Wildlife Society Bulletin, Volume 49, Issue 1, March 2025.Surveys of small mammal populations at airports inform species relative abundance estimates, information used by airport biologists to direct management to reduce strike risk. From our review, we identified snap‐traps and tracking tunnels as the two most‐promising small‐mammal survey methods for most airports, considering the breadth of applications ...

Journal of Forensic Sciences, Volume 69, Issue 6, Page 1985-1995, November 2024.Abstract Vertebrate scavengers represent important taphonomic agents that can act on a body, particularly when in an outdoor environment. Understanding the effects of these agents will direct how and where to search for human remains and influence the likelihood of discovery in a particular region.

Oikos, Volume 2024, Issue 10, October 2024.Apex scavengers can perform an important ecosystem service by rapidly removing carrion, in turn regulating nutrient cycling linked to carcass decomposition. Yet, our understanding of the biotic and abiotic factors that influence rates of apex scavenging and their behaviour around carrion remains limited, in part because of the absence of replicated ...
