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 …
Taxonomic And Seasonal Variation Among Extant Hyracoids Based On Dental Microwear Texture Analysis, Ann Marie Walcutt
Taxonomic And Seasonal Variation Among Extant Hyracoids Based On Dental Microwear Texture Analysis, Ann Marie Walcutt
Graduate Theses and Dissertations
A number of works have been published on habitats and diets of living hyraxes but much remains to be learned about the paleoenvironment contexts of the much larger, more dominant but now extinct forms of the order. Here, I analyze the dental microwear of modern hyraxes to assess dietary and ecological relationships among the four extant species of Procaviidae: Heterohyrax brucei, Procavia capensis, Dendrohyrax arboreus, and Dendrohyrax dorsalis. The purpose of this study was to establish an extant baseline series for the interpretation of microwear texture patterns, and inference of diets, of extinct members of the …
