Trait-based approaches to marine microbial ecology
… this thesis is to understand how the functional traits of species, biotic interactions, and the environment jointly regulate the community ecology of phytoplankton. In Chapter 2, I examined Continuous Plankton Recorder observations of diatom and dinoflagellate abundance in the North Atlantic …

Trait-based modeling of larval dispersal in the Gulf of Maine
… provide a comprehensive assessment. Individual-based models (IBMs) that couple ocean circulation and particle-tracking models provide a unique ability to examine larval dispersal patterns with high spatial and temporal resolution. Obtaining accurate results with IBMs requires simulating a …

Trait-based approaches to understanding the response of forest understory herbs to environmental variation
… will respond to future environmental change. Trait-based approaches can thus offer valuable insights into how populations and communities will respond to environmental change by providing a mechanistic link between plant traits and the environment. This dissertation explores the trait-mediated …

Trait-Based Individual Differences on Discomfort Glare Rating Responses and Related Visual Contrast Sensitivity
… designed to investigate the relationship between Trait-based Individual differences (neuroticism and extraversion) and glare subjective responses as well as the actual contrast sensitivity when exposed to the same manipulated glare condition. In addition, the relationship between the glare …

A functional and trait-based approach in understanding ant community assembly in the Soutpansberg Mountains, South Africa
… community assembly. However, functional and trait diversity can further explain the factors driving community assembly because they capture different aspects of species ecological roles such as habitat requirements and resource use. To investigate the factors shaping community assembly along …

Developing a trait-based approach to understand <i>Sphagna</i> responses to hydrological stress in the Flow Country
… Blanket bog resilience depends strongly on the traits and plasticity of Sphagnum mosses, which dominate blanket bog vegetation communities. However, the scales at which Sphagna traits vary, and how they translate to ecohydrological function remains unclear. This thesis develops a trait-based …

Personality and leader emergence in groups
Trait-based approaches to leadership have been around for a long time. Starting out as one of the original theories of leadership, research in the area of trait- based perspectives began to slow and give way to other, different domains of predicting leadership in the 1950s. Only recently has there …

Preschoolers' Use of Personality Traits to Predict and Explain Behavior
… research has shown that children are aware of trait information and that children as young as age 5 use trait-based information to predict future behavior. Preschoolers are also aware of gender stereotypes and may use these stereotypes to predict and explain behavior. The current study …

A comparison of community composition analyses for the assessment of responses to wood-ash soil amendment by free-living nematodes
… was responsive to experimental treatments. Trait-based approaches (Maturity Index (MI) and Body Size Spectra (BSS)) were more sensitive to forest harvest and wood-ash amendment treatments. The efficacy of these methods was also qualitatively compared. Of all methods, the BSS were found to be …

Intraspecific trait variation and community assembly in old-field grasslands
<p>Trait-based approaches are increasingly used in plant community ecology, but previous research has largely ignored functional trait variation within species. Here I investigated the role of intraspecific trait variation in community assembly and responses to spatial and temporal environmental …

Customer Tolerance In Community Pharmacy
… were examined to inform this dissertation. Based on theoretical reasoning and evidence identified in the literature, hypotheses were generated to evaluate the concept of customer tolerance in community pharmacy. Hypothesis 1: service quality is positively associated with customer tolerance …

Alternative Organizations in Memory for Trait-Relevant Behaviors
… hierarchically organized in memory in terms of trait concepts. In the research paradigm commonly used to test these theories, adjectives describing the traits are presented before the behaviors, and the behaviors usually have little in common other than the abstract trait concepts. This paradigm …

Competition among simulated plant species in a toy local vegetation model
Kleidon and Mooney (2000) used a trait-based simulation of plants in the global environment to argue that the tropics maintain more biodiversity because a greater variety of strategies of allocation of functional parts, such as leaves and roots, lead to viable physiologies in those regions. …

Does the Motive Matter? The Role of Intended Effects in Characterizing Actions and Inferring Personality Traits
… by which perceivers characterize an action as trait-relevant (e.g., that is a kind action), and infer a trait based on this action (e.g., that is a kind person). The primary purpose of this model is to explore the possibility that actions are characterized as trait-relevant based on the …

Linking Plant and Soil Microbial Diversity via Plant Functional Trait Ecology
… highlights the need for a more mechanistic, trait-based understanding. This dissertation examines how various attributes of plant diversity influence microbial diversity, and if the patterns observed at species scale can be extended to mixed communities. Using a combination of monocultures …

MECHANISMS AND IMPACTS OF LAND-USE CHANGE ON FRESHWATER FISHES IN SUNDALAND
… within Sundaland were identified using trait-based criteria, and simulated species losses were found to have relatively mild impacts on trait richness. Next, I found that mouth positions mediate effects of riparian vegetation on fish occurrences in oil palm streams. Following this, I …

An analysis of the evolution of life history traits
… evolution and relationship between life-history traits has been a popular research topic over the past several decades. Previous research has generally focused on a single or small number of species, or a single trait. I utilized multiple trait-based datasets to create a collection of 777 …

Exploring an Interactive Measure for Preferences in Early Childhood
… the three experiments, children failed to show trait-based: Experiments 1 & 2) or category-based: Experiment 3) social preferences. They did, however, show preferences for the target objects when the target was highly familiar, and thus more interesting than the distracter object. Possible …
