Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 2, Page 305-322, June 2026.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Comparing timing and routes of migration based on ring encounters and randomization methods [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
A method for comparing two migration routes is introduced. In the method are needed approximations of the average daily positions which are computed based on averages of dates and of positions in a window sliding through the encounters ordered in ...

Prospecting for informed dispersal: Reappraisal of a widespread but overlooked ecological process

open access: yesEcology, Volume 107, Issue 5, May 2026.
Abstract Prospecting for a future breeding site is an essential component of informed natal and breeding dispersal. It allows individuals to reduce the uncertainty of their environment by gathering personal and social information about the local quality of alternative breeding areas and make informed emigration and settlement decisions.

Brown Trout Abundance in Boreal Streams With Large Wood

open access: yesEcology of Freshwater Fish, Volume 35, Issue 2, April 2026.
ABSTRACT Large wood has been found to be a crucial component in riverine ecosystems. However, due to the heavy channelization of rivers and intensive forestry practices over the past few decades, the amount of large wood in these ecosystems has decreased worldwide. River restoration aims to mitigate the effects of channelization and restore the channel

Age‐related changes of oxidative status and immune function in a long‐lived seabird

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Experimental studies in humans and laboratory species have shown that the decline of the immune system with age (immunosenescence) and the accumulation of oxidative damage to macromolecules are two key contributors to the onset and progression of the ageing process. Although laboratory models have provided important insights, the physiological basis of

Testing for assortative mating based on migratory phenotypes in the Common Tern (Sterna hirundo)

open access: yesAvian Research
Tracking and mating data of Common Terns (Sterna hirundo) breeding in a single colony in north-eastern Germany were used to test for assortative mating in regards to migratory phenotypes.

Mallard response to experimental human disturbance on sanctuary areas is mediated by hunting

open access: yesWildlife Biology, Volume 2026, Issue 2, March 2026.
Wildlife managers often provide spatial sanctuaries for wildlife to escape both lethal (e.g. hunting) and non‐lethal (e.g. non‐consumptive recreation) human disturbance. However, as societal interest in outdoor recreation continues to climb, many areas face added pressure to allow recreation, yet studies increasingly demonstrate negative effects of ...
