Thermal Quality Explains Shift In Habitat Association From Forest To Clearings For Terrestrial-Breeding Frogs Along An Elevation Gradient In Colombia, Zachary Lange Jul 2019

Thermal Quality Explains Shift In Habitat Association From Forest To Clearings For Terrestrial-Breeding Frogs Along An Elevation Gradient In Colombia, Zachary Lange

Masters Theses

Tropical ectotherms are considered particularly sensitive to changes in the thermal environment from climate change and habitat alteration. Understanding how such species’ thermal physiology relates to their habitat associations in thermally heterogeneous landscapes may help us predict responses and develop sound conservation strategies for the future. We conducted a mark-recapture study of three terrestrial breeding anuran species (Pristimantis medemi, P. savagei, P. frater) in adjacent forest and anthropogenic clearings at field sites spread across seven elevations (415-1350 m asl) in the Colombian Andes. We also performed thermal preference and critical thermal maximum assays in the lab to investigate the relationship ...


Ecological Considerations And Application Of Urban Tree Selection In Massachusetts, Ashley Mcelhinney Jan 2019

Ecological Considerations And Application Of Urban Tree Selection In Massachusetts, Ashley Mcelhinney

Masters Theses

Trees provide countless environmental, economic, and societal benefits to the urban environment, and may become increasingly important to maintaining environmental quality and human well-being in the face of increasing urbanization and climate change. However, trees in these urban areas are rapidly diminishing across the United States. Much of this loss can be prevented with proper planning and management, focused on selecting tree species that are both well-suited to the area’s growing conditions and able to survive the many stress factors in an urban setting. Choosing which tree species to plant in Massachusetts is especially challenging considering the lack of ...
