The Interactive Effects Of Pesticide Exposure And Infectious Disease On Amphibian Hosts, Katherine M. Pochini
The Interactive Effects Of Pesticide Exposure And Infectious Disease On Amphibian Hosts, Katherine M. Pochini
Open Access Theses
Natural systems are home to a multitude of natural and anthropogenic stressors, which draw an array of effects on ecological communities. While these effects have been investigated individually, it is important, given the routine co-occurrence of these stressors, to understand their interactive effects. Pesticide exposure and infectious disease are two common, co-occurring stressors that each have documented detrimental effects on species and, as evidence suggests, may have interactive effects. Moreover, existing research suggests that these interactive effects are highly context dependent, eliciting different results based on species, disease agent, toxin, and environment. Given the variability with which species may experience …
The Decline Of Cisco Coregonus Artedi At Its Southern Range Extent: Stock Biology And Management Implications, Andrew E. Honsey
The Decline Of Cisco Coregonus Artedi At Its Southern Range Extent: Stock Biology And Management Implications, Andrew E. Honsey
Open Access Theses
The cisco Coregonus artedi is distributed throughout northern North America and is relegated to coldwater, oligotrophic systems. Populations of cisco located at the species' southern range extent, including northern Indiana and southern Michigan, have drastically declined over the past century, seemingly due to a combination of climate warming and exacerbation of hypolimnetic hypoxic conditions via intensive land-use and resulting increases in nutrient loading. Apart from their decline, information on southern ciscoes is lacking, including basic stock demography and genetic variability. Such information may shed light on the likely sustainability (or lack thereof) of remaining populations. The first portion of this …
