Welfare and Clinical Assessment on Physical Captures Followed by Anesthesia in Apennine Chamois (Rupicapra pyrenaica ornata)
The Apennine chamois (Rupicapra pyrenaica ornata) is one of the rarest subspecies in Italy, listed in Annexes II and IV of the Habitats Directive and currently included as a vulnerable subspecies in the International Union for Conservation of Nature (IUCN) Red List. The Maiella National Park population has recently been defined as a source population […]
Long-term capture and handling effects on body condition, reproduction and survival in a semi-aquatic mammal
In long-term individual-based field studies, several parameters need to be assessed repeatedly to fully understand the potential fitness effects on individuals. Often studies only evaluate capture stress that appears in the immediate weeks or breeding season and even long-term studies fail to evaluate the long-term effects of their capture procedures. We investigated effects of long-term […]
It’s in the bag: Corticosterone levels and behavioral responses of Eastern Bluebirds (Sialia sialis) vary with type of holding bag
Birds react to capture, restraint, and handling by both innate physiological and behavioral means, which function to promote survival. Following capture, small birds are typically placed into holding bags for transport and restraint before data collection and/or banding. We examined physical characteristics of holding bags constructed from opaque cotton cloth or polyester mesh and measured […]

Prediction, location, collection and transport of jellyfish (Cnidaria) and their polyps
Abstract 10.1002/zoo.20218.abs With growing interest in research and display of living jellyfish workers are realizing the difficulty in obtaining and maintaining a healthy collection consistently. This report identifies the causes for the uncertainty in locating specimens and summarizes the latest technology, techniques and avenues for acquiring jellyfish for captive maintenance. Responsibility inherent with jellyfish transport […]
Effects of capture and temperature stresses on plasma steroid concentrations in male tuatara (Sphenodon punctatus)
The effects of capture and temperature stresses on plasma concentrations of testosterone (T) and progesterone (P) were examined in wild male tuatara (Sphenodon punctatus), the only living sphenodontid reptile. Free-roaming male tuatara on Stephens Island, New Zealand, had low levels (0.3–0.5 ng/ml) of plasma T in July (winter), and high levels (15–17 ng/ml) in January […]
Cognitive bias in a non-human primate: husbandry procedures influence cognitive indicators of psychological well-being in captive rhesus macaques
The measurement of ‘cognitive bias’ has recently emerged as a powerful tool for assessing animal welfare. Cognitive bias was initially, and widely, studied in humans, and describes the way in which particular emotions are associated with biases in information processing. People suffering from clinical levels of anxiety or depression, for example, interpret ambiguous events more […]

Hematological parameters and the variations resulting from stress of Alouatta caraya during a wildlife rescue program in Brazil
Deforestation and habitat fragmentation are major threats to the conservation status of New World primates, such as the howler monkey (Alouatta caraya) in Brazil, where vegetation destruction is often associated with projects such as Small Hydro Power Plant (SHP) construction. The resulting stress from the implementation of this type of enterprise may be a factor […]
Immediate effects of capture on nest visits of breeding blue tits, Cyanistes caeruleus, are substantial
Although capture, handling and marking of birds as well as taking samples from them are ubiquitous and, in most cases, unavoidable procedures in ornithological research, their immediate effects on the individuals remain largely unstudied. Here, we present data over 3 years from a long-term field study on the breeding biology of the blue tit. Parents […]
