Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

open access: yesEthology, Volume 132, Issue 5, Page 336-348, May 2026.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

Sperm quality improvement of cryopreserved boar semen through colloidal centrifugation gradient

open access: yesCzech Journal of Animal Science
Boar semen cryopreservation is limited due to the lower thermal shock resistance of sperm cells. A colloidal centrifugation gradient is an enhancement to cryopreservation that could improve the frozen boar semen quality.

Cryopreservation of boar semen

open access: yes, 2012
The work in hand investigates storage time and freezability of epididymal Mangalica boar semen regarding several quality parameters of the spermatozoa after storage both at 5°C and 17°C for 24 hours followed by freezing and thawing. The results obtained from the work should help to support the survival of the species by saving genetic material for the ...

Liproxstatin-1 improves boar sperm quality during in vitro liquid preservation at 17°C, associated with reduction of oxidative stress and ferroptosis markers

open access: yesFrontiers in Veterinary Science
ObjectiveThe plasma membrane of boar sperm is notably enriched in polyunsaturated fatty acids (PUFAs). During extended liquid storage of boar semen at 17°C, reactive oxygen species (ROS) derived from lipid peroxidation progressively accumulate within ...

Effects of cryopreservation on the motile sperm subpopulations in semen from Asturiana de los Valles bulls [PDF]

open access: yes, 2013
The aim of this study was to identify different motile sperm subpopulations in ejaculates from an autochthonous bull breed (Bos taurus) and to determine possible modifications in these subpopulations resulting from cryopreservation.
