Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...
Aim The hypothesis that habitat fragmentation negatively influences biodiversity stems from island biogeography and metapopulation theory which predict negative impacts of decreasing patch size on richness and distribution patterns. Empirical support of this idea is weak in terrestrial systems, though tests of fragmentation effects are typically confounded with landscape composition...
Automated sound broadcast systems have been used to address a variety of ecological questions, and show great potential as a management tool. Such systems need to be reliable because treatments are often applied in the absence of a human observer and system failure can cause methodological ambiguity. During the breeding...

Over the past fourteen years since the attacks on the World Trade Center on September 11, 2001, Americans of varied political persuasions have continually identified the day as a defining moment in the history of the nation, which caused a rupture in the cultural rhythm and psyche. This sensibility is...
Copper antimony sulfide (CAS) is a ternary material that is of research interest for thin film photovoltaic applications due to its high absorption coefficient and tunable bandgap. The material is also ideal for sustainable manufacturing due the constituent elements being earth-abundant and less toxic than solar cell absorbers like gallium...
Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...
