Seasonal changes in fresh semen quality and freezability in boar semen

The Indian Journal of Animal Sciences, 2014
The objective of this study was to investigate the effect season on sperm quality in fresh and cryopreserved boar sperm. Ejaculates (59) of fertile boars were divided into 4 groups according to season: winter, spring, summer and autumn. Semen volume, sperm motility, sperm concentration, percentage of morphologically abnormal spermatozoa, total number ...

Selenium Nanoparticles as Potential Antioxidants to Improve Semen Quality in Boars

Animals, 2023
Selenium is an essential compound which can influence the fertility of boars by a greater margin. In past decades, research was mainly focused on a bioavailability of various selenium forms and the effect on semen quality. Recently, nanotechnology has expanded the possibilities of selenium supplementation research.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.
