Factors Affecting The Distribution Of Malayan Sun Bear In Htamanthi Wildlife Sanctuary, Northern Myanmar, Min Hein Htike
Factors Affecting The Distribution Of Malayan Sun Bear In Htamanthi Wildlife Sanctuary, Northern Myanmar, Min Hein Htike
Masters Theses
To understand the modeling challenges and to examine the important factors considered in Malayan sun bear (Helarctos malayanus) distribution studies, we reviewed 33 peer-reviewed articles published from 2003-2023. These studies used 54 environmental or anthropogenic variable types to investigate the distribution, habitat preference, and home range composition of sun bears. Most variable types are human disturbance (n=4), climate (n=3), topography (n=1), vegetation (n=11), or other ecological factors (n=3). Nevertheless, a number of rarely used variables might also be useful to include in future evaluations (i.e., food abundance), and observational evidence suggests that predator occurrence could also be informative. …
Habitat Associations Of Priority Bird Species And Conservation Value On Small, Diversified Farms In New England, Isabel Brofsky
Habitat Associations Of Priority Bird Species And Conservation Value On Small, Diversified Farms In New England, Isabel Brofsky
Masters Theses
In recent decades, New England agriculture has become increasingly characterized by small, diversified farming operations with values deeply rooted in community and conservation. In sharp contrast to large-scale, high-intensity agriculture currently typified by the majority of North American farms, New England farmers commonly prioritize ecologically beneficial production practices such as reduced chemical inputs, integrated pest management (IPM), low tillage, cover cropping and crop rotation, and retention of natural habitats like woody hedgerows and herbaceous strips. Public support and demand for local, sustainable food, evidenced by the success of CSA (Community Supported Agriculture) in the region, has helped to bolster this …
Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel
Masters Theses
In order to ascertain the degree of compatibility in developmental restructuring and behavioral plasticity between two fish species frequently made subject of laboratory research (Metriaclima zebra & Danio rerio), alternative trophic niche exposure experiments utilizing novel three-prong feeding treatments were conducted to obtain morphometric data, which demonstrated both species do bear some degree of plasticity. The results are somewhat complicated by differences in locality of detectable restructuring, which may be due to disparity in the form-function relationship for each species’ lineage. Each is notable in the manner of respective species’ jaw protrusion, as it is driven by anterior …
Ant (Hymenoptera: Formicidae) Assemblages In Three New York Pine Barrens And The Impacts Of Hiking Trails, Grace W. Barber
Ant (Hymenoptera: Formicidae) Assemblages In Three New York Pine Barrens And The Impacts Of Hiking Trails, Grace W. Barber
Masters Theses
Ants are ecologically important, environmentally sensitive, widespread, and abundant, yet ant assemblages of many habitats remain poorly understood. Ants in inland barrens of New York State (NY) barely have been studied, but the limited data suggest such habitats are likely to support uncommon ant species and high species density for the region. To increase knowledge of these assemblages, I systematically collected ants from three inland barrens systems in NY, to create species lists and measure species density. I also investigated how hiking trails — a common man-made disturbance — may be impacting ant assemblages in these early-successional, disturbance-dependent ecosystems. My …
Assessing Wild Canid Distribution Using Camera Traps In The Pioneer Valley Of Western Massachusetts, Eric G. Leflore
Assessing Wild Canid Distribution Using Camera Traps In The Pioneer Valley Of Western Massachusetts, Eric G. Leflore
Masters Theses
With the ever-increasing human population, more people reside in urban areas than ever before; this is having marked effects on the landscape and in turn, wildlife. This study uses automatically triggered wildlife cameras to assess the distribution of three carnivore species (coyotes, Canis latrans; red foxes, Vulpes vulpes; and gray foxes, Urocyon cinereoargenteus) around the Pioneer Valley of Massachusetts in relation to a gradient of human development. Cameras were placed at 141 locations within the 320-km2 study area over the course of three field seasons (3,052 trap nights). Relative abundances for fourteen other species and site …
