Survivorship Of Columbian Black-Tailed Deer In A Predator-Free Environment, Grace Hope Barthelmess
Survivorship Of Columbian Black-Tailed Deer In A Predator-Free Environment, Grace Hope Barthelmess
Honors Projects
Future management of Columbian black tailed deer (Odocoileus hemionus columbianus) populations requires an understanding of survivorship and potential drivers of mortality. Little is currently known about the survivorship of O. h. columbianus, specifically in a predator-free environment. Analyzing the survivorship of deer in these contexts may be crucial for wildlife conservation efforts throughout the United States, as it could provide insight into how deer populations may be impacted by lack of population control by predation. Here, I present age analysis of O. h. columbianus based on the cementum annuli of the lower first molar in 489 males …
An Overview Of The Current Research On Epiphyte Ecology, Kelsey Inman-Carter
An Overview Of The Current Research On Epiphyte Ecology, Kelsey Inman-Carter
Honors Projects
Epiphytes are non-parasitic, photosynthetic organisms that depend on other photosynthetic host organisms for support. Epiphytes can be found both in aquatic and terrestrial habitats. The interactions between epiphytes and their hosts can vary based on both their habitat and the features of individual hosts. This review explores the many facets of epiphyte research, including: the diversity of epiphytes in aquatic and terrestrial habitats; the effects of host-epiphyte interactions on the hosts; and the abiotic and biotic interactions that together determine epiphyte community composition.
Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman
Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman
Honors Projects
Amblypygids are nocturnal arthropods which live in cluttered habitats and possess the ability to navigate home after displacements of up to ten meters. Homing amblypygids rely on olfactory and tactile information gathered by their antenniform legs to navigate successfully. Given that odor signals encountered in nature are complex and dynamic, navigation via olfaction presents unique challenges related to signal uncertainty. To understand how amblypygids perceive perceive complex odors and what they learn from them, individuals of the subtropical amblypygid P. marginemaculatus were trained to associate a blend of two odors with a shelter and tested on three treatments: the reinforced …
Mitigation Of Negative Effects Of Ocean Change On Oysters By Eelgrass And Its Implications For Aquaculture In Midcoast Maine, Fiona G. Ralph
Mitigation Of Negative Effects Of Ocean Change On Oysters By Eelgrass And Its Implications For Aquaculture In Midcoast Maine, Fiona G. Ralph
Honors Projects
Species interactions are important to organisms and to the ecosystems they inhabit. These interactions, sometimes facilitations, can result in increased resiliency for both species. When facilitation occurs, organisms co-assist with physiological and environmental stressors. As anthropogenic impacts become more stressful for modern organisms, these interactions could offer a solution for many species. Ocean acidification has been shown to be detrimental to many calcifying organisms including oysters. More acidic conditions can slow the process of shell calcification, which can slow growth rates. This effect could directly impact the robust oyster farming business in Midcoast Maine. Because of its possible importance to …
