Food Availability and Behavior of Youth EFNEP Participants in Virginia
… youth are disproportionately affected by low food access, low dietary quality, and high levels of obesity. The Expanded Food and Nutrition Education Program (EFNEP) is designed specifically to assist limited resource youth and adult audiences to acquire the knowledge, skills, attitudes, and …

Feeding the South: An Assessment of Food Availability in Rural Mississippi
… project is to investigate Mississippi’s rural food environment by assessing the food resources available to rural Mississippians. The primary objectives were to identify sample locations in each of the four cultural regions of Mississippi and determine the food resources available to residents …

Local food availability, diet and obesity: Development and empirical testing of a complex theory
… range of chronic diseases. Aspects of the local food environment, including food availability, have been linked to less healthy diets and increased body weight in adults. However, there is limited theory development to guide the synthesis of empirical studies or the design and evaluation of …

Burrowing Behavior of the Fiddler Crab <i>Uca panacea</i> in Relation to Food Availability
… studies were conducted to assess the effect of food availability on burrowing in the Gulf coast fiddler crab, Vea panacea. In the field, crabs were observed for droving behavior through visual observations; evidence for this behavior was assessed further by determining sediment organic content. …

Relation of crystalline style function to food availability and environmental conditions in South African mussels
… ability of the mussels to effectively utilise a food resource, and this may be a mechanism which partially accounts for their differing distributions. This work examines the quantitative and qualitative nature of the suspended particulate food resource at the boundary of the east and west coast …

Effects of temperature and food availability on the reproductive ecology of an arid-zone bird
… ecology. However, the potential for resource availability to moderate environmental temperature effects on birds' behaviour, physiology, morphology, and success during breeding remains understudied. I investigated these lesser-known concepts through monitoring breeding, conducting a …

Exploring the food landscape in Ann Arbor and Ypsilanti, MI: Neighborhood racial characteristics and food availability
<p>The neighborhood retail food environment is an indicator of short- and long-term health conditions. Disparities in Covid-19 health outcomes have been identified as specifically impacting minority populations in Ann Arbor and Ypsilanti, MI. This study explores these cities' neighborhood retail …

Effect of Food Availability and Predation on the Population Dynamics and Spacing Behavior of Prairie Voles
… effects. In this study, I manipulated food availability and predation and used a factorial design with replicates. I tested the hypothesis that food availability, predation, and spacing behavior interact to limit densities of prairie voles. My results show that supplemental, …

The importance of fine-scale flow processes and food availability in the maintenance of soft-sediment communities
… organic content, microbial content, stability, food supply, and larval supply. One hypothesis for animal-sediment associations is that settling larvae are transported as passive particles and are sorted into different sedimentary habitats much like sediment grains. To test the hypothesis that …

Fluctuating human activity and associated anthropogenic food availability affect behaviour and parental care of Red-winged Starlings
Increased food availability associated with urbanisation is widely recognised as one of the key factors influencing avian demography. Temporal fluctuations in food availability, tied to variation in human presence, are of particular interest as they occur frequently in urban environments, but their …

Food availability and fat composition of diet in Eastern Province, Saudi Arabia, with reference to coronary heart disease
… areas. The aims were to provide information on food availability and the coronary heart disease mortality and its implications among the population, taking into consideration fat and fatty acid profile in the diet. The data were collected in three approaches; (1) food availability survey based …

Habitat selection, food availability, and reproductive success of southwestern willow flycatchers on the South Fork Kern River, California
… to determine how habitat characteristics and food availability affect E. t. extimus demographics, and to make inferences about possible reasons for the decline. My first objective was to determine southwestern willow flycatcher habitat selection on the Kern on two spatial scales: territory and …

The Effects of Limited Winter Food Availability on the Population Dynamics, Energy Reserves, and Feather Molt of the Swamp Sparrow
… zone winters posed by cold weather coupled with food scarcity. These challenges are often assumed to occur, but are rarely experimentally tested. I hypothesized that the naturally occurring, lower abundances of food in temperate zone winters limit a bird's ability to acquire optimal energy and …

Socioecology of Adult Female Vervet Cercopithecus Aethiops and Patas Monkeys Erythrocebus Patas in Kenya: Food Availability, Feeding Competition, and Dominance Relationships
… both used an A. drepanolobium woodland habitat. Foods here were randomly and closely distributed in space and less abundant per feeding site compared to foods in the A. xanthophloea riverine habitat, a second habitat used by vervet monkeys. The hierarchy exhibited by female vervet monkeys in the …

Factors influencing food availability for the endangered south-eastern Red-tailed Black Cockatoo Calyptorhynchus banksii graptogyne in remnant stringybark woodland, and implications for management.
… to determine which aspects of resource availability actually limit population size. The endangered south-eastern Red-tailed Black Cockatoo Calyptorhychus banksii graptogyne is highly specialised, feeding almost entirely on seeds of the closely related stringybark eucalypts Eucalyptus …

Socio-Economic Determinants of Modern Agricultural Technology Adoption in Multiple Food Crops and Its Impact on Productivity and Food Availability at the Farm-Level: A Case Study from South-Eastern Nigeria
… of modern agricultural technology in multiple food crops and the corresponding impacts on productivity and food availability at the farm-level in South-eastern Nigeria. In this study, three major food crops (i.e., rice, yam and cassava) and two elements of modern technologies (i.e., HYV seeds …

Most of our mechanistic knowledge of these processes comes from terrestrial mammals and insects, while there are major knowledge gaps for marine invertebrates. My dissertation focuses on the interactions of circadian rhythms and …
