Use Of Vertical Enclosure Space And Species-Typical Locomotion By A Rehabilitating Spider Monkey (Ateles Fusciceps), Jake Funkhouser
Use Of Vertical Enclosure Space And Species-Typical Locomotion By A Rehabilitating Spider Monkey (Ateles Fusciceps), Jake Funkhouser
Undergraduate Honors Theses
With wild spider monkey populations in decline, investigations contributing to captive welfare, and successful rehabilitation and reintroduction knowledge is increasingly pressing. Quantifying and analyzing the appropriateness of naturalistic enclosure designs to foster species-typical behaviors is an effective way to address both of these needs. This study investigates enclosure space use, vertical space preference, substrate use, positional/postural modes, and interactions with human caregivers of a wild-caught, pet-trade rehabilitant Columbian black spider monkey (Ateles fusciceps rufiventris, N = 1). Video data collected daily from August to October 2015 via focal animal sampling (from 08:00 to 10:00) at Alouatta Sanctuary, Panama …
The Mental Number Line In Domestic Chicks, Samantha Noyek
The Mental Number Line In Domestic Chicks, Samantha Noyek
Undergraduate Honors Theses
The estimation of number by humans shows evidence for a mental number line in which magnitude increases from left to right. Rugani, Vallortigara, Priftis, and Regolin (2015) recently reported a similar mental number line in domestic chicks. This is an unexpected result given the role of language and culture in the human mental number line. Animals do not possess language or arithmetic concepts like the mental number line. Because the results reported by Rugani et al. (2015) seem improbable from this perspective, my study sought to determine whether the observations of Rugani et al. (2015) occur reliably. I tested for …
