A dog makes a difference: exploration of potential biases in moose‐hunting associated citizen science

Wildlife Biology, EarlyView.
The collection of citizen data is often employed to generate insights regarding species distribution, population sizes, and population structure; however, biases inherent in citizen science are seldom addressed. In this study, we examined the factors influencing hunters' observations of moose, Alces alces, during the moose hunting season in Finland. By

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Wildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

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 ...

Parturition timing and the pre‐ and post‐partum behaviour of female moose assessed using animal‐borne video and movement‐based approaches

Wildlife Biology, EarlyView.
Limited information on moose calving behaviour, including parturition timing, cow‐calf interactions, and pre‐ and post‐partum movement patterns hinder our ability to define calving phenology and habitat use. GPS‐collars were deployed on 89 female moose over five years, including eight collars equipped with animal‐borne video and environmental data ...
