| Investigation of male Golden-winged Warbler plumage traits as sexually selected ornaments |
2015 |
1058 |
Substantial evidence has now demonstrated that fertilization competition selects for the most effective status-signaling and female-stimulating ornaments and that females measurably benefit from choosing males with the most elaborate ornaments. Study... |
| Morphological and ecological causes of interspecific aggression between golden-winged and chestnut-sided warblers. |
2015 |
948 |
Interspecific aggression is widespread throughout the animal kingdom, yet research that documents the evolutionary and ecological consequences remains limited and unclear. Aggressive behaviors are often indicative of an ecological niche overlap betwe... |
| Influence Of Human Activity On The Stress-Hormone Levels And Nestling Growth Of Wild Breeding Tree Swallows |
2016 |
921 |
Anthropogenic disturbance can influence the physiology of individuals in wild breeding populations and have consequences for population ecology and conservation biology. The response to stressors in daily life is mediated by the hypothalamo-pituitary... |
| Estimates Of Eastern Hellbender (Cryptobranchus Alleganiensis Alleganiensis) Occupancy And Detection Using Two Sampling Methods |
2016 |
1773 |
Environmental DNA (eDNA) is a non-invasive survey method that is an increasingly popular alternative for detecting rare aquatic species. Although recent studies have demonstrated the efficacy of eDNA in detecting the presence of aquatic species, the ... |
| A Test of Parental Preferences for Offspring Sex and Ornamentation in Eastern Bluebirds (Sialia sialis) |
2011 |
2054 |
Avian parents protect their fledglings from predators. Given parents have limited resources, they face trade-offs when simultaneously rearing multiple offspring. Parents might favor particularly valuable offspring. Offspring characteristics influence... |
| Predator And Environmental Effects On The Polymorphic Egg Masses Of Spotted Salamanders (Ambystoma maculatum) |
2016 |
1693 |
Polymorphisms may be maintained if selection intensity and gene flow vary across a species’geographic range. Jelly coats of amphibian eggs are under many different selective forces,such as predators and external environment interactions. Spotted sala... |
| Variation In Plumage Coloration Of Eastern Bluebirds (Sialis Sialis) In Relation To Weather And Geography |
2017 |
1862 |
Plumage coloration is thought to convey individual quality and influence reproductive success for many species. Few studies have investigated how weather variation during molt impacts ornamental traits. Eastern bluebirds (Sialis Sialis), an insectivo... |
| Associations Between Parasitic Blow Flies And The Breeding Density And Synchrony Of Cavity Nesting Passerines |
2018 |
842 |
Understanding transmission dynamics of parasites can assist in both disease control and conservation. Parasite load is traditionally viewed as a function of host density, but this model fails in some instances, usually depending on the life cycle of ... |
| Potential Effects Of Aggression, Site, And Proximate Determinants That Facilitate Tree Swallow Range Expansion |
2016 |
1314 |
Breeding range expansion occurs when individuals disperse to novel environments over successive breeding seasons and it is expected that both range expanding and native species will be affected. Additionally, native species can experience increased a... |
| Personalities Of Mated Pairs And Parental Provisioning Coordination In Eastern Bluebirds |
2018 |
514 |
Animal personality is characterized by consistent similar reactions by an individual across contexts and time. Although individual personality is known to influence fitness, the extent to which similarity of pair personality influences fitness in mon... |
| Trophic Ecology Of An Imperiled Giant Salamander (Cryptobranchus A. Alleganiensis) In Southern Appalachian Streams |
2019 |
1262 |
Eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) are large, aquatic amphibians that are a conservation priority in much of their range. However, our understanding of their role in aquatic foodwebs is limited. Prior gut content and obs... |
| Maternal Personality May Mitigate The Negative Impacts Of Anthropogenic Noise On A Free-Living Bird |
2020 |
531 |
Although the effects of anthropogenic noise pollution on wildlife populations are well documented, little research has focused on the importance of animal personality in mitigating these impacts. Bold individuals may be less likely to suffer than mee... |
| Intervention Methods for Spurring Emergent Literacy in Children Who Are Deaf or Hard Of Hearing By Hearing Parents: A Literature Review |
2015 |

This thesis focuses on the methods hearing parents may employ to spur emergent literacy in their children who are deaf or hard of hearing. Children who are deaf or hard of hearing are naturally at risk for language and literacy delays. Children with ... |
| Consistency of Stress Hormone Profiles and Associations between Personality and Hormone Levels in a Wild Breeding Bird |
2015 |
