Two wild adult Nubian ibex (Capra nubiana) were captured and admitted to the Hebrew University Veterinary Teaching Hospital with various neurologic signs, including alerted mentation, head tilt, and pathologic nystagmus. The lesion in the central nervous system was localized to the forebrain in one ibex and to the cerebellum of the other. Both ibex's were diagnosed with brain cyst using computed tomography (CT). Craniectomy was performed to remove the cysts, and both animals returned to their natural environment after a rehabilitation period. Parasitologic examination revealed cysts of Taenia multiceps coenurus. This is the first report to describe the neurologic signs, CT findings, surgical procedure, and follow-up postsurgery information in wild Capra nubiana.
Animal social relationships emerge from interactions in multiple
ecological situations. However, we seldom ask how each situation
contributes to the structure of a population or to the social position
of individuals. Griffon vultures interact in multiple situations,
including when roosting, flying, and feeding. These social interactions
can influence population-level outcomes such as disease transmission and
information sharing. We examined the contribution of each ecological
situation to the social structure of the population and to individuals’
social positions using GPS-tracking. We found that the number of
individuals each vulture interacted with was best predicted by diurnal
interactions. However, the strength of social bonds was best predicted
by interactions on the ground – both during the day and at night but
not by interactions while flying. Thus, social situations differ in
their impact on the relationships that individuals form. Given the
conservation importance of vultures, these findings can inform wildlife
management actions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
