Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, Volume 222, Issue 1, June 2026.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Nematodes of the small intestine of African buffaloes, Syncerus caffer, in the Kruger National Park, South Africa

Onderstepoort Journal of Veterinary Research, 2013
The abundance and distribution of parasitic helminths in populations of African buffaloes, Syncerus caffer, have not been well documented. A total of 28 buffaloes of different ages and sexeswere sampled in the Kruger National Park, South Africa, for ...

Evolution of Ivermectin Resistance in the Nematode Model Caenorhabditis elegans: Critical Influence of Population Size and Altered Emodepside Efficacy

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT The emergence and spread of anthelmintic resistance represent a major challenge for treating parasitic nematodes, threatening mass‐drug administration control programs in humans and zoonotic hosts. Currently, experimental evidence to understand the influence of management (e.g., treatment dose and frequency) and parasite‐associated factors (e ...

The Relationship Between Immunopathology and Body Condition of Mixed‐Age Ewes

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Ill thrift in ewes, characterised by less than desirable body condition, is a multifactorial condition often attributed to nutritional deficits, though immunopathological factors may also play a role. This study investigated associations between body condition scores (BCS) and immunopathological states in 120 mixed‐age ewes grazing pasture over 4 ...

Body condition score and weight are effective targeted selective treatment indicators for gastrointestinal nematodes in premating ewes

Veterinary Record, Volume 198, Issue 3, Page e85-e91, 31 January/7 February 2026.
Abstract Background Ewe reproductive performance is key for flock profitability but can be impacted upon by gastrointestinal nematode (GIN) infections. Farmers commonly deworm ewes pre‐mating, yet concerns regarding anthelmintic resistance increase pressure to reduce wormer use.

Identification of β‐galactosidases along the secretory pathway of Nicotiana benthamiana that collectively hamper engineering of galactose‐extended glycans on recombinant glycoproteins

Plant Biotechnology Journal, Volume 24, Issue 1, Page 224-238, January 2026.
Summary Glycosylation is an important aspect for many biopharmaceuticals, including vaccines against parasitic helminths. Plants, especially Nicotiana benthamiana, have proven to be excellent production hosts for biopharmaceuticals with tailor‐made glycosylation.

Tropical Pastures and Lamb Health: The Role of Litter and Forage Cultivars in the Dynamics of Gastrointestinal Nematodes Under Continuous Stocking in the Cerrado

Advances in Agriculture, Volume 2026, Issue 1, 2026.
In tropical grazing systems, the interaction between forage structure and microenvironment plays a key role in the epidemiology of gastrointestinal nematodes (GIN) affecting small ruminants. This study evaluated the effect of tropical forage cultivars on GIN infection and related health indicators in lambs during the dry season in the Brazilian Cerrado.
