Development and importance of brachiation: How enclosure design affects activity patterns in captive gibbons (Hylobates lar)
Title
Development and importance of brachiation: How enclosure design affects activity patterns in captive gibbons (Hylobates lar).
Creator
Schwartz, Michele R., Florida Atlantic University, Broadfield, Douglas C.
Abstract/Description
Knowing how to keep captive gibbons can have an impact on the field of anthropology and, in turn, improve the care of these animals in captivity. A brachiating structure designed for enriching gibbon habitat was constructed on one of two islands in a captive enclosure. The data collected was analyzed on time spent brachiating compared to time spent on the ground. A key factor in collecting data was the placement of the observer with respect to the proximity of the gibbons being observed. In...
Show moreKnowing how to keep captive gibbons can have an impact on the field of anthropology and, in turn, improve the care of these animals in captivity. A brachiating structure designed for enriching gibbon habitat was constructed on one of two islands in a captive enclosure. The data collected was analyzed on time spent brachiating compared to time spent on the ground. A key factor in collecting data was the placement of the observer with respect to the proximity of the gibbons being observed. In this study the gibbons spent more time on the grass when observing them at close range. The gibbons spent a greater amount of time on the brachiating structure when observed from a distance. Despite complications in data collection, the gibbons displayed preference for the redesigned structure, and were observed brachiating more frequently on the stable supports than the rope supports in the unmodified enclosure.

seeds of structure: Exploring the chimpanzee mind
Title
The seeds of structure: Exploring the chimpanzee mind.
Creator
Halloran, Andrew R., Florida Atlantic University, Broadfield, Douglas C.
Abstract/Description
There are certain properties of the human mind which allow abstract thought. These properties are responsible for the ability to create myth (or explanations of the unknown), cosmology, and culture. They are the seeds of all human phenomena not attributable to instinct. These properties can be isolated as the capacity for numeric logic and the mind functioning in terms of binary oppositions. The long held paradigm sees the human species as unique in possessing these qualities and well as the...
Show moreThere are certain properties of the human mind which allow abstract thought. These properties are responsible for the ability to create myth (or explanations of the unknown), cosmology, and culture. They are the seeds of all human phenomena not attributable to instinct. These properties can be isolated as the capacity for numeric logic and the mind functioning in terms of binary oppositions. The long held paradigm sees the human species as unique in possessing these qualities and well as the phenomena they yield. In order to challenge this paradigm, a two experiments are conducted on a chimpanzee to see if she possessed these properties. She successfully completed the cognitive tests on both experiments, thus implicating the human species as not unique in its abstractions.

A camera trap study of the cyptic, terrestrial guenon cercopithecus lomamiensis in Central Democratic Republic of the Congo

Abstract/Description
From October-December 2013, we conducted a study of the newly discovered primate species lesula, Cercopithecus lomamiensis, in the DR Congo. We placed 41 camera traps inside a 4 km2 grid outside the proposed Lomami National Park (LNP). We compared an analysis of 140 lesula events over 1,683 camera trap days from the heavily hunted Okulu area to a pilot study (38 events over 462 camera trap days) at the Losekola study site within the LNP. Our data show an unexpected result: capture probability...
Show moreFrom October-December 2013, we conducted a study of the newly discovered primate species lesula, Cercopithecus lomamiensis, in the DR Congo. We placed 41 camera traps inside a 4 km2 grid outside the proposed Lomami National Park (LNP). We compared an analysis of 140 lesula events over 1,683 camera trap days from the heavily hunted Okulu area to a pilot study (38 events over 462 camera trap days) at the Losekola study site within the LNP. Our data show an unexpected result: capture probability of lesula (0.08) is the same at both the hunted and non-hunted sites. This is in contrast to the sharp decline in capture probability of all other medium-to-large terrestrial mammals at the Okulu site. These findings suggest lesula’s cryptic behavior is an important adaptation buffering the species from the impacts of hunting. This study also expands knowledge on minimum group size, terrestriality, diet, and times of activity.
