The physiological ecology of the specialist lagoon amphipod, Gammarus insensibilis
… has suggested that detailed information on the ecology of lagoon specialist species is essential to ensure management strategies are relevant to the lagoonal species. This study addresses this issue by providing information about the monthly reproductive investment and energy-balance as well as …

Life history and physiological ecology of the lizard, Cordylus Giganteus
Cordylus giganteus is a large, terrestrial, viviparous lizard, endemic to the Highveld grasslands of South Africa. Its distribution is limited and its conservation status is vulnerable. Autopsy and mark-recapture methods were used to study the seasonal aspects of its reproductive cycle, diet, …

The Physiological Ecology of Fraser FIr in Southern Appalachian Cloud Forests
… exert a strong influence on Fraser fir physiological ecology and microclimate that ultimately determine Fraser fir distribution. One goal of the research presented here was to characterize the microclimate of these forests during cloud immersed conditions, compared to cloudy and sunny …

Integrating bioenergetics and foraging behavior : the physiological ecology of larval cod (Gadus morhua)
How do larval cod, Gadus morhua, balance foraging effort against the high cost of swimming in a viscous hydrodynamic regime? A respirometry system was developed to measure the activity metabolism of individual larvae. The cost of swimming was modeled as a power-performance relationship (energy …

Behavioral and Physiological Ecology of Scorpion Venom Expenditure: Stinging, Spraying, and Venom Regeneration
… a comprehensive understanding of the behavioral ecology of venom. To explore the behavioral and physiological ecology of venom expenditure by scorpions, I conducted four studies of the medically significant Buthid scorpion <em>Parabuthus transvaalicus</em>. The first two experiments revealed that …

Behavioural and physiological ecology of the Namib Desert dune ant, Camponotus detritus emery
The ecology of Camponotus detritus was examined over two years at six sites across the Namib Desert. This common species was found to fill an important role in the dune ecosystem as the major honeydew consumer, apparently limited chiefly by intraspecific competition for food. Each colony, …

The importance of cotyledon functional morphology and patterns of seed reserve utilization for the physiological ecology of neotropical tree seedlings
Seed mass, resource makeup of seed, and functional morphology of cotyledons are three traits that together determine patterns of seed reserve utilization by seedlings during their critical establishment stage. The main objective of this thesis is to examine how these traits differentiate the …

The Importance of Fog for Carbon Gain, Water Balance, and Foliar Uptake in Southern Appalachian Cloud Forests
… the effects of cloud immersion on whole plant physiological ecology, including carbon uptake and water balance needed to be examined.

Comparative Gene-Centric Metagenomics of the Rumen Microbiome
… microbial populations may alter their physiological profile and possess critical enzymatic components essential for the breakdown of fiber-based feeds. The objectives of this research were to provide information pertaining to the physiological ecology of both of the rumen community and …

Integrated analysis of relationships between 3D-structure, leaf photosynthesis, and branch transpiration of mature Fagus sylvatica and Quercus petraea trees in a mixed forest stand
… is one of the remaining challenges in plant physiological ecology. This thesis uses the historically new chances for the description of 3D-complexity of beech and oak forests that come along with the rapid developments in information technology: It gives a comprehensive description of …

Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae
… can provide valuable information regarding the physiological ecology of an organism. However, there have been few studies wherein bite force in sharks has been considered. Herein I report on a study of the bite force of four species of sharks with particular emphasis on that of the atlantic …

Plant size and intraspecific variability in vascular epiphytes
A central objective of many ecophysiological investigations is the establishment of mechanistic explanations for plant distributions in time and space. The important, albeit mostly ignored, question arises as to the nature of the organisms that should be used as representative in pertinent …

Biology and conservation of the endangered Hawaiian Dark-rumped Petrel (Pterodroma phaeopygia sandwichensis)
… of the Haleakala population. A study of the physiological ecology of breeding birds was undertaken to examine the adaptations of the Dark-rumped Petrel's eggs, and those of adult birds and nestlings, to the factors that constrain their breeding cycle. These factors include an apparently …

The role of incubation temperature in determining avian phenotype: implications for avian ecology, life history evolution, and conservation
… history theory, bioenergetics. immunology, and physiological ecology to investigate the importance of incubation temperature to avian phenotype. I found that incubation temperature affects a suite of traits important for future development, survival and reproduction in a species of birds. Using …
