Journal of Zoology, 271(1), 27-36. https://doi.org/10.1111/j.1469-7998.2006.00176.xThe 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.

Behavioural Processes, 73(2), 228-230. https://doi.org/10.1016/j.beproc.2006.05.012It 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...
