Parasite, 2023 Polystomatidae is a monogenean family whose representatives infect mainly (semi)-aquatic tetrapods. Species of Sphyranura Wright, 1879 exhibit ectoparasitism on salamander hosts, with molecular work supporting their inclusion within Polystomatidae, at an

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.This study reveals an 11.6% prevalence of sheep ked (Melophagus ovinus) in South Gondar Zone, Northwest, Ethiopia, with significant associations to sex, body condition, season, and agro ecology. Infested sheep showed significantly lower packed cell volume (PCV), indicating anaemia.

Molecular Ecology, Volume 35, Issue 21, November 2026.ABSTRACT Biological invasions on islands provide a natural framework to study how dispersal and connectivity influence evolutionary and ecological processes. The avian nest parasitic fly, Philornis downsi—first recorded in Darwin's finch nests in 1997—causes high mortality in endemic land birds, yet its inter‐island and sex‐specific patterns of ...

Group Size and Ectoparasitism Affect Daily Survival Probability in a Colonial Bird [PDF]
, 2004 Little is known in general about how group size or ectoparasitism affect survival in colonial animals. We estimated daily within-season survival probabilities for nesting adult and recently fledged juvenile cliff swallows (Petrochelidon pyrrhonota) at ...

Avian Research, 2022 Several ectoparasites parasitise nestlings decreasing their body condition, growth and survival. To minimise any loss of fitness due to ectoparasites, birds have developed a wide variety of defence mechanisms, potentially including hatching asynchrony ...

Oikos, Volume 2026, Issue 10, October 2026.Elucidating the determinants of parasite infection levels of individuals within a population is a basic but important step for understanding the roles of parasites in natural systems. Among intraspecific studies on vertebrate hosts and metazoan parasites, host body size (length/mass) is probably the most frequently reported factor determining parasite ...
