The seasonality of gastrointestinal nematode species abundance (excluding Nematodirus) in sheep of different classes across New Zealand

New Zealand Journal of Agricultural Research, Volume 68, Issue 7, Page 2436-2455, December 2025.
ABSTRACT A survey on nine farms across New Zealand assessed the seasonality and species composition of gastrointestinal nematodes in three sheep classes: lambs (<1 year), 2‐tooth ewes (1–2 years), and mixed age ewes (>2 years). Monthly faecal samples from each class underwent faecal egg counting and deep amplicon sequencing of cultured third‐stage ...

Genetic identification of gastrointestinal parasites in the world's most endangered ungulate, the hirola (Beatragus hunteri)

Veterinary Record, Volume 196, Issue 12, 21/28 June 2025.
Abstract Background The hirola (Beatragus hunteri) is the world's most critically endangered antelope. Its parasitic fauna has never been genetically characterised, raising questions about its possible role in the species' population decline. This study aimed to assess the presence of gastrointestinal parasites in hirolas and their transmission ...

Cooperia Ransom 1907

3.1 Occurrence of Cooperia in deer in the Czech Republic Despite the relatively high number of deer examined from various parts of the Czech Republic in 2018–2022 (116 deer belonging to seven ruminant species, not shown), Cooperia nematodes occurred occasionally. They were present in only three out of 25 red deer (prevalence = 12.0%) and four out of 30

Walter's Duiker (Philantomba walteri Colyn, 2010): A Literature Review on a Recently Identified and Potentially Vulnerable Species

Ecology and Evolution, Volume 14, Issue 11, November 2024.
The Dahomey Gap, a dry corridor, divides the African tropical rainforests into distinct blocks. With an annual rainfall below 1200 mm, it hosts savannas, crops, and isolated fragments of gallery forests, swamp forests, and semi‐deciduous forests. Despite strong human influence, the discovery of Walter's duiker in 2010—a small antelope intermediate ...
