While capture-mark-recapture studies provide essential individual-level data in ecology, repeated captures and handling may impact animal welfare and cause scientific bias. Evaluating the consequences of invasive methodologies should be an integral part of any study involving capture of live animals. We investigated short- and long-term stress responses to repeated captures within a winter on the physiology, behaviour, and reproductive success of female Svalbard reindeer (Rangifer tarandus platyrhynchus). Short-term responses were evaluated using serum concentrations of glucocorticoids and catecholamines during handling, and post-release recovery times in heart rate and activity levels. Repeated captures were associated with an increase in measured catecholamines and glucocorticoids, except cortisone, and delayed recovery in heart rate but not activity. Four months later, in summer, individuals captured repeatedly in winter exhibited a small increase in behavioural response to human disturbance and had a lower probability of being observed with a calf, compared to animals not captured, or captured only once. Our findings imply that single annual capture events have no significant negative consequences for Svalbard reindeer, but repeated captures within a season may impact offspring survival in the same year. Such unanticipated side effects highlight the importance of addressing multiple indicators of animal responses to repeated captures.

Osteochondrosis (OC) is a multifocal pathology, which takes place in both articular-epiphyseal cartilage complex (immature joint cartilage covering the ends of growing long bones) and growth plate in a variety of mammalian species. The disorder is characterized by failure of endochondral ossification, and is considered as one of the most common primary causes of degenerative joint disease in domestic animals [2, 3]. One of the most recurrent manifestations of OC is the osteochondrosis dissecans (OCD), which is considered to be involved in failure of cellular differentiation in growing cartilage, leading to its dramatic thickening or retention, emergence of fissures and eventual focal loss of cartilage flaps into the joint cavity. The detached fragments can be responsible of severe joint inflammation, which can lead to subsequent development of secondary osteoarthritis (OA) [4]. 2b1af7f3a8
