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

Medical 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 ...

'Tipping the Balance': Karl Friedrich Meyer, Latent Infections, and the Birth of Modern Ideas of Disease Ecology [PDF]

, 2015
The Swiss-born medical researcher Karl Friedrich Meyer (1884–1974) is best known as a ‘microbe hunter’ who pioneered investigations into diseases at the intersection of animal and human health in California in the 1920s and 1930s.

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, Volume 248, Issue 5, Page 873-887, May 2026.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Exploitation of Erythrina dominguezii Hassl. (Fabaceae)nectar by perching birds in a dry forest in western Brazil

Brazilian Journal of Biology
Among the vertebrate pollinated plants, the genus Erythrina includes tree species in which birds are the pollen vectors. Two groups in this genus may be distinguished: a) the hummingbird, and b) the perching bird pollinated species. Erythrina dominguezii

Hybridization and Immunology in Animals: A Review

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Hybridization can reshape immune function by introducing novel genetic variation and combining parental immune traits. Across animal taxa, this process may influence resistance, tolerance, and pathogen dynamics, with important implications for disease ecology and One Health.

Sensory preferences and personality traits of captive red crowned kakariki (Cyanoramphus novaezelandiae) and Antipodes Island parakeets (C. unicolor) : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology at Massey University, Palmerston North, New Zealand [PDF]

, 2017
The way in which most animals sense and interpret the environment around them differs from species to species. Even two closely related species such as the red-crowned parakeet (Cyanoramphus novaezelandiae) and the Antipodes Island parakeet (C. unicolor)
