Nest Predation in the Canarian Houbara Bustard (Chlamydotis undulata fuertaventurae): An Experimental Study Using Artificial Nests

Ecological Research, Volume 41, Issue 3, May 2026.
We investigated nest predation in the endangered Canarian houbara bustard using 229 artificial nests and camera traps. Ravens were identified as the main predators, and predation rates were influenced by raven density, vegetation cover, stone cover, and road density.

Comparative Pharmacokinetics of Intranasal or Intramuscular Atipamezole in Unsedated Dogs and Efficacy for Reversal of Xylazine Sedation

Journal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 3, Page 257-266, May 2026.
ABSTRACT The objectives of this study were to evaluate ATIP pharmacokinetics (PK) in healthy Beagle dogs after IM and IN dosing (Phase I), and to compare the rate of reversal of IM versus IN routes for xylazine (XYL) sedation (Phase II). This study was comprised of two sequential, randomized, crossover experiments. The initial PK study dosed ATIP by IN
