A New Approach To Modeling Vertical Stiffness In Heel-Toe Distance Runners, Iain Hunter

Faculty Publications

Various models have been used to describe distance running technique. Among these, the mass-spring model is fairly simple to use and apply, but when employed as a model, does not predict vertical force accurately especially when a heel strike is exhibited. The purpose of this article is to demonstrate how the mass-spring model can be modified to provide a simple, yet accurate prediction of ground reaction forces in distance running. Sixteen subjects ran on a force instrumented treadmill. Vertical forces during running at a self-selected pace were collected at 500 Hz. Vertical stiffness was calculated using the conventional mass-spring model …

Evidence For Survival Of Pleistocene Climatic Changes In Northern Refugia By The Land Snail Trochoidea Geyeri, David Posada, Markus Pfenninger, Frederic Magnin

Faculty Publications

The study of organisms with restricted dispersal abilities and presence in the fossil record is particularly adequate to understand the impact of climate changes on the distribution and genetic structure of species. Trochoidea geyeri (Soos 1926) is a land snail restricted to a patchy, insular distribution in Germany and France. Fossil evidence suggests that current populations of T. geyeri are relicts of a much more widespread distribution during more favourable climatic periods in the Pleistocene. Results: Phylogeographic analysis of the mitochondrial 16S rDNA and nuclear ITS-1 sequence variation was used to infer the history of the remnant populations of T. …

Determination Of The Botanical And Chemical Composition Of The Pasture Diet Selected By Llamas (Lama Glama) During The Rainy Season In The Community Of Pujrata, Cristóbal Achu Nina

Theses and Dissertations

Llamas (Lama glama) take advantage of poor natural forage (grasses and others) due to their efficient digestive physiology that is adapted for this type of forage. The problem now faced is the gradual exhaustion of the native grassland (low phytomass production). The vegetation does not cover the dry matter consumption requirements, and less so the nutrient requirements, of these animals. Because of this there is the necessity of determining the botanical composition, pasture selection by plant parts, and chemical composition of what llamas ingest in order to improve these animals' nutrition in the pasture. This study occurred at the Larqa …

Bergmann's Rule In Ectotherms: A Test Using Freshwater Fishes, Mark C. Belk, Derek D. Houston

Faculty Publications

Understanding patterns of variation in body size within and among species is a central question in evolutionary ecology (Schlichting and Pigliucci 1998). The most well known pattern of variation in body size is Bergmann's rule (Bergmann 1847; Mayr 1956). The intraspecific version of Bergmann's rule holds that within endothermic species, body size increases with increasing latitude (or decreasing temperature; Blackburn et al. 1999; Ashton et al. 2000). In general, mammals conform to this rule (Ashton et al. 2000).
