COMMUNITY ECOLOGY OF CHILEAN SANDY BEACHES
<p>Monthly abundances and life history traits of peracarid species (Orchestoidea and Excirolana), and the anomurid crab Emerita analoga were studied during May, 1978 to April, 1980 in an exposed sandy beach of southern Chile (Mehuin Beach, Bahia de Maiquillahue). Beach characteristics differed …

Community ecology of small-mammal pollinated proteas
The floral characteristics of small-mammal pollinated (SMP) Protea species have been assessed in a number of previous studies. This study aimed to determine whether the inflorescences of Protea canaliculata, Protea sulphurea and Protea humiflora possess these traits and are pollinated by small …

A Spatio-temporal Phylogenetic Approach to Community Ecology
… about the data. For angiosperms in a plant community in Toronto, I show that species trait and phylogenetic relationships are spatially-dependent within the community level. For my system, multiple processes likely co-occur within the community and influence species assembly patterns at …

Parasites in freshwater mussels: community ecology and conservation
… to understandings of what drives parasite community structure across scales, while the latter furthers knowledge on how the conservation of host species or the functioning of ecosystems may be influenced by those parasite communities. In this thesis, I study both perspectives using a …

Stewardship gardening: multifarious meanings through community, ecology, and food
… these interviews, themes of situation, human ecology, spirituality, reflection, interaction, practice, food, stewardship, conviction, and purpose emerge as part of the greater story of religion and ecology. Historical background, analysis of local stewardship gardens, and these personal …

Songbird community ecology and habitat selection in the Chicago area
… were only weakly correlated with avian community structure (i.e. a matrix of all species and their relative abundances at each plot), both species richness and the conservation value of birds within a plot decreased with an increase in European buckthorn (Rhamnus cathartica) tree …

Community Ecology Of Soil Microbes In Southeast Usa Oak-Pine Woodlands
… have important effects on plant growth and plant community ecology; however, the relationships between trees and soil microbial communities are still relatively poorly understood. Here i examine several of these relationships. Chapter 1 examines how ecological restoration and environmental …

Multitrophic Interactions in a Prairie Insect Community: Ecology, Behavior, and Conservation
… With my research, I characterized the community of insect species that inhabit flowering stems of Silphium laciniatum L. and S. terebinthinaceum Jacquin. I used stable isotope analysis to clarify the trophic position of several of the key members of the community, determining that the …

The community ecology of a riverine turtle assemblage in the Tennessee River Gorge
In attempting to characterize a community, it is necessary to measure ecological attributes to quantitatively describe the unique aspects of that community and to make comparisons. This thesis reports on a long-term investigation of the community ecology of a turtle assemblage in the Tennessee …

The population and community ecology of small freshwater ponds: Assigning process to pattern
… interactions) when studying population and community dynamics. Multiple studies have documented that divergent population and community structures can arise in similar habitats when colonization history differs. For example, early colonists may hinder, inhibit, or in some cases facilitate …

Community ecology of aquatic insects in forested headwater streams in the southern Appalachians
Competing paradigms of community assembly emphasize different mechanisms for predicting patterns in biogeography. Niche assembly emphasizes the role of environmental gradients as filters that organize a metacommunity by locally selecting colonizers with similar functional traits, whereas dispersal …

Influence of Gizzard Shad on Fish Community Ecology in Northeastern South Dakota Glacial Lakes
<p>Walleye Sander vitreus are the most popular sport fish in South Dakota, while yellow perch Perca flavescens are important both ecologically as prey for walleye and economically as an important sport fish themselves. Gizzard shad Dorosoma cepedianum are also an ecologically important species in …

Managing disturbance in the longleaf pine ecosystem: effects of managed fire regime characteristics on fire hazard and community ecology at multiple spatial scales
… from the perspective of both fire hazard and community ecology: the two main management objectives for prescribed burning in longleaf pine forests. Research addressing these objectives is presented in three chapters. First, in Chapter 3 I examined the effects of season-of-burn on shrub and …
