Journal of Animal Ecology, EarlyView.Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds
Journal of Animal Ecology, EarlyView.Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...

Effects of Year and Season on Calving Interval in Romanian Brown Cattle
Scientific Papers Animal Science and Biotechnologies, 2023 The aim of the current research was to determine the influence of calving year and season on calving interval (CI) in Romanian Brown breed. A total of 250 data recorded from 150 lactations of 50 Romanian Brown cows raised between 2018 and 2020 were ...

Elephant space use and habitat selection change across drought timescales
Journal of Animal Ecology, EarlyView.Drought threatens wildlife worldwide, but little is known about wildlife behaviour during drought. This study combines 19 years of elephant GPS data with drought conditions at three timescales. Key findings include that elephants (i) move less during drought at a 1‐month timescale and (ii) change habitat selection across drought timescales.

Nutritional aspects related to the interval between calves
Scientific Electronic Archives, 2017 It is known that the demand for products of bovine origin increases every day in the world, and Brazil, which has the largest commercial herd of cattle on the planet, does not stay behind when it comes to raising beef cattle and milk. Despite our efforts to offer the best product, we are faced with difficult challenges in the country when it comes to ...

Integrative Zoology, EarlyView.This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation
