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 […]

Short- and long-term repeatability of docility in the roe deer: sex and age matter

Behavioural consistency is a key assumption when evaluating how between-individual differences in behaviour influence life history tactics. Hence, understanding how and why variation in behavioural repeatability occurs is crucial. While analyses of behavioural repeatability are common, few studies of wild populations have investigated variation in repeatability in relation to individual status (e.g. sex, age, condition) […]

ADVANCES IN ANIMAL WELFARE FOR FREE-LIVING ANIMALS

Over several decades, animal welfare has grown into its own free-standing field of scientific study, from its early beginnings in laboratory animal research to eventually include exhibited animals and farm animals. While it has always been present to some degree, consideration of animal welfare for free-ranging animals has lagged behind, developing as a field of […]

ANIMAL WELFARE FROM MOUSE TO MOOSE-IMPLEMENTING THE PRINCIPLES OF THE 3RS IN WILDLIFE RESEARCH

The concept of the 3Rs (replacement, reduction, and refinement) was originally developed for improving laboratory animal welfare and is well known in biomedical and toxicologic research. The 3Rs have so far gained little attention in wildlife research, and there could be several reasons for this. First, researchers may prioritize the welfare of populations and ecosystems […]
