Ecosystem Functional Consequences Of Body Size Variation In An Apex Predator (Ambystoma jeffersonianum)
<p>Biodiversity is often emphasized at the species level where each species is assigned a mean functional trait value. However, populations within a species, and individuals within a population, often exhibit considerable intraspecific functional variation. Therefore, instead of focusing on …

Using Mesocosms to Model Optimal Levels of Body Size Variation in Larval Spotted Salamanders (Ambystoma maculatum)
Body size is a critical aspect of an organism’s biological identity mediated by various biotic and abiotic factors. Body size historically been approached through “single optima” approaches, but body size variation modifies both inter- and intraspecific interactions and impacts competition-driven …

Ecological Assembly of Leaf-Litter Anuran Communities Across a Neotropical Land-Bridge Archipelago
The conspicuous variation in time and space of richness and composition of biological communities has intrigued ecologists for decades. In this dissertation, I explore the patterns and ecological mechanisms that underlie the community assembly of leaf-litter anurans on a Neotropical archipelago. I …

Effects of body size on goose behavior: lesser snow goose and Ross's goose
Body size is highly variable among geese, both at intra- and interspecific levels. Interspecific variation in several behaviors has been attributed to differences in body size in geese: incubation constancy, tendency to maintain family units, and time spent foraging. Body size has important …

Anatomy, Implant Selection and Placement Influence Spine Mechanics Associated with Total Disc Replacement
… modeling approach quantified shape and alignment variation of the lumbar spine by characterizing variability of shape and size of individual vertebra, relative alignment of relevant segments, and overall anatomy of the lumbar spine. Statistical shape models of single vertebrae revealed that the …

The consequences and implications of ecology on body size distributions in social insects
… success and survival of an organism (e.g. size at birth, age at maturity, and size at maturity). One of the major tenets of life history theory is that finite resources must be allocated to the development of traits associated with growth, defense, and reproduction. Consequently, investment …
