Secret lives of maned wolves (Chrysocyon brachyurus Illiger 1815): as revealed by GPS tracking collars (2006)
Journal Article
de Melo, L., Sabato, M., Magni, E., Young, R., & Coelho, M. (2007). Secret lives of maned wolves (Chrysocyon brachyurus Illiger 1815): as revealed by GPS tracking collars. Journal of Zoology, 271(1), 27-36. https://doi.org/10.1111/j.1469-7998.2006.00176.x

The maned wolf Chrysocyon brachyurus is a nocturnal and shy species, which has proven difficult to study in the field; consequently, data about its behavioural biology are almost absent from the scientific literature. However, recent advances in glob... Read More about Secret lives of maned wolves (Chrysocyon brachyurus Illiger 1815): as revealed by GPS tracking collars.

A note on the effect of the full moon on the activity of wild maned wolves,< i> Chrysocyon brachyurus</i> (2006)
Journal Article
Sabato, M., de Melo, L., Magni, E., Young, R., & Coelho, C. (2006). A note on the effect of the full moon on the activity of wild maned wolves,< i> Chrysocyon brachyurus. Behavioural Processes, 73(2), 228-230. https://doi.org/10.1016/j.beproc.2006.05.012

It is well established in the scientific literature that animal prey species reduce their activity at times of high predation risk. In the case of nocturnal animals this occurs when there is a full moon; however, the response of predators to the chan...

Behavioural responses of captive-born greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae) submitted to antipredator training (2006)
Journal Article

Human activities have been diminishing greater rhea Rhea americana (Linnaeus, 1758) populations throughout their natural distribution. The reintroductions of captive-born greater rheas have been tried but without success; since the individuals reintr...

The antipredator training is a powerful tool now being used to help the reintroduced animals to recognise and escape from their predators. Testing the memory capacity of the animals after antipredator training is important to evaluate if the applicat...

Shyness and boldness in greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae): the effects of antipredator training on the personality of the birds (2006)
Journal Article
de Azevedo, C., & Young, R. (2006). Shyness and boldness in greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae): the effects of antipredator training on the personality of the birds. #Journal not on list, 23(1), https://doi.org/10.1590/S0101-81752006000100012

The shy-bold continuum is an axis of behavioural variation for some species, but the consequences of shyness and boldness in antipredatory behaviour is unknown. Bold animals have the tendency to be predated first after release in comparison to shy an...

Marsupials from space: fluctuating asymmetry, geographical information systems and animal conservation (2006)
Journal Article
Teixeira, C., Hirsch, A., Perini, H., & Young, R. (2006). Marsupials from space: fluctuating asymmetry, geographical information systems and animal conservation. Proceedings of the Royal Society B: Biological Sciences, 273(1589), https://doi.org/10.1098/rspb.2005.3386

We report the development of a new quantitative method of assessing the effects of anthropogenic impacts on living beings; this method allows us to assess actual impacts and to travel backwards in time to assess impacts. In this method, we have cross... Read More about Marsupials from space: fluctuating asymmetry, geographical information systems and animal conservation.

Applying animal learning theory: Training captive animals to comply with veterinary and husbandry procedures (2004)
Journal Article
Young, R., & Cipreste, C. (2004). Applying animal learning theory: Training captive animals to comply with veterinary and husbandry procedures. Animal Welfare Journal, 13(2), 225-232. https://doi.org/10.1017/S0962728600026968

Animals within zoo environments are learning continuously: they learn signals that predict when food is going to arrive or that the presence of a certain person means that something unpleasant may happen. They may learn to control their environment a... Read More about Applying animal learning theory: Training captive animals to comply with veterinary and husbandry procedures.

Trends in the captive breeding of threatened and endangered birds in British zoos, 1988--1997 (2004)
Journal Article

The aim of this study was to assess trends in captive breeding of threatened and endangered bird species in British zoos. The measures we recorded were: 1) the total number of species held, 2) the percentage of species held that are listed in the IUC...

Do domestic pigs in controlled environments contrafreeload? (2003)
Journal Article
Young, R., & Lawrence, A. (2003). Do domestic pigs in controlled environments contrafreeload?. Journal of Applied Animal Welfare Science, 6(4), 309-318. https://doi.org/10.1207/s15327604jaws0604_5

Many experiments report that animals will work (lever press) for food in the presence of freely available identical food. This phenomenon has attracted the attention of applied ethologists because it seems to prove that animals have a need to express...

The efficacy of the model--rival method when compared with operant conditioning for training domestic dogs to perform a retrieval--selection task (2003)
Journal Article

Traditionally, dogs have been trained by operant conditioning techniques; that is, dogs make a desired behavioural response and this response is reinforced by a reward such as food. This type of training is very effective in training dogs to perform...

Uncloaking the magician: Contributions of comparative psychology to understanding animal training (2002)
Journal Article
Young, R. (2002). Uncloaking the magician: Contributions of comparative psychology to understanding animal training. #Journal not on list, 15(2), https://doi.org/10.46867/C47G75

The training of animals is an ancient anthropogenic process; however, it was not until the birth of comparative psychology, as a science, that the mysterious ways of the animal trainer were formally explained. In this review I will discuss the contri... Read More about Uncloaking the magician: Contributions of comparative psychology to understanding animal training.

Do domestic dogs show any evidence of being able to count? (2002)
Journal Article
