Comparative body size relationships in pocket gophers and their chewing lice [PDF]

Biological Journal of the Linnean Society, 2000
Abstract In this paper, we use the method of independent contrasts to study body size relationships between pocket gophers and their chewing lice, a host-parasite system in which both host and parasite phylogenies are well studied. The evolution of body size of chewing lice appears to be dependent only on the body size of their hosts, which confirms ...

Chewing lice (Insecta: Phthiraptera) found on Griffon Vultures (Gyps fulvus) from a wild breeding colony in central Spain.

Vulture News, 2023
The Griffon Vulture (Gyps fulvus) is a social species which breeds in colonies and feeds in groups. This can facilitate horizontal transmission of ectoparasites between conspecifics. In 2015, in the province of Guadalajara, Spain, 28 vultures from a wild

An interdisciplinary approach to improving conservation outcomes for parasites. [PDF]

Conserv Biol
Abstract Parasites represent a significant proportion of Earth's biodiversity and play important roles in the ecology and biology of ecosystems and hosts, making them an important target for conservation. Despite increasing calls to prioritize protection for parasites in the academic literature, they remain undervalued and underrepresented in global ...

Ecological implications of fish removal: Insights from gut‐content analysis of roach (Rutilus rutilus) and European perch (Perca fluviatilis) in a eutrophic shallow lake

Journal of Fish Biology, Volume 103, Issue 6, Page 1321-1334, December 2023., 2023
Abstract Large reductions in fish biomass are common both as a method of managing lake ecosystems by fish removals (biomanipulation) and as naturally occurring fish kills. To further understand how fish reductions change feeding patterns of fish, we studied the diets of small‐ to medium‐sized roach (Rutilus rutilus) and European perch (Perca ...

Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers

Freshwater Biology, Volume 68, Issue 7, Page 1176-1193, July 2023., 2023
Abstract The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human–predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate cause of salmon population declines, otters that kill adult salmon in rivers before they spawn impact the salmon spawning ...
