Chemical Communication In House Mice (Mus Musculus): Can They Recognize Gender From The Anogenital, Harderian Gland Or Mouth/Nose Odor?, Dawn Michele Andrews
Chemical Communication In House Mice (Mus Musculus): Can They Recognize Gender From The Anogenital, Harderian Gland Or Mouth/Nose Odor?, Dawn Michele Andrews
Dissertations and Theses
Identifying the sensory systems animals employ to communicate chemically and the function of the chemical signals facilitates further understanding of chemical communication. Increased knowledge of how animals use the olfactory and vomeronasal systems in order to interpret the meaning of body odors will aid in developing a more detailed organization of chemosensory pathways. The message that each body odor contains can change from species to species.
The purpose of this thesis was to study three previously untested body odors in house mice (M. musculus) for their role in gender recognition of conspecifics. These odors are the anogenital (feces, …
Irrigation, Power, And Salmon: The Case For Voluntary Water Transfers In The Columbia Basin, Eric Kuhner
Irrigation, Power, And Salmon: The Case For Voluntary Water Transfers In The Columbia Basin, Eric Kuhner
Center for Urban Studies Publications and Reports
This paper begins with a brief history of water law in the west, illustrating the roots of conflict over water allocation. A more detailed examination of activities in the Columbia Basin follows, describing the many parties affected by issues of water use and the overlapping institutional structures that govern the river and its water.
Sources of pressure to change the current pattern of water use are then considered. These include requirements to protect endangered salmon runs and the change over time in the relative values of water for power production and irrigation. This section demonstrates how changes in the value …
Captive Environmental Influences On Behavior In Zoo Drills And Mandrills (Mandrillus), A Threatened Genus Of Primate, Erik Terdal
Captive Environmental Influences On Behavior In Zoo Drills And Mandrills (Mandrillus), A Threatened Genus Of Primate, Erik Terdal
Dissertations and Theses
Drills (Mandrillus leucophaeus) are an endangered species of African monkey (Cercopithecidae), and their sole congener the mandrill (Mandrillus sphinx) is vulnerable to extinction. Both species are threatened in the wild by deforestation and hunting.
Drills have a poor record of captive reproduction. Many individuals appear to have behavioral deficiencies which interfere with reproduction. Thus, the zoo population of drills does not serve as a “hedge” against the species’ total extinction: drills are endangered in captivity as well as in the wild. Mandrills, by contrast, reproduce well in captivity. Information on the behavior of mandrills in captivity may help zoo managers …
