Reproductive biology of three gadiform fish species through the Mediterranean deep-sea range (147-1850 m)

open access: yesScientia Marina, 2002
Knowledge of deep-sea reproductive biology is slight and interpretations of reproductive strategies in deep-sea fishes are controversial. Since the Mediterranean is a fairly stable and constant sea, we might expect a consistent pattern of reproduction of

Vaginal temperature and collar activity variations in relation to fecal progestagens of captive moose

open access: yesAnimal Biotelemetry, 2023
Background Timing of reproductive events can be crucial for a species’ population growth and stability. Accurate detection of reproductive phenology presents a challenge to scientists studying wild species, including moose (Alces alces). Currently, there
