The nest defense and nest-destroying behaviors of house wrens
Presentations of three potential nest intruders were used to investigate house wren nest defense behavior, while regular nest box checks provided information regarding house wren nest-destroying behavior. During nest defense trials, male wrens were typically more active in defense than females in …

Gopher tortoise nest-site selection at burrows and the influence of nest environment on hatching success
Nesting and early life is a period of high mortality for many turtle species, so understanding how turtles select nest sites, and how those nest sites impact hatching success, may be important for successful species conservation. In this research, my objective was to 1) understand how the …

Sources of Nest Failure in Mississippi Sandhill Cranes, Grus canadensis pulla: Nest Survival Modeling and Predator Occupancy
… pulla). Lack of information on sources of nest failure hinders effective management to increase recruitment. I examined sources of nest failure for 54 nests at the Mississippi Sandhill Crane National Wildlife Refuge, 2008-2009. Nest cameras identified predation as the primary source of …

Bayesian hierarchical models for estimating nest survival
… OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Nest survival rate is a critical value in avian study to evaluate the landbirds populations. The widely used likelihood-based logistic regression model was evaluated in the first part of the dissertation. In this part, we investigated the importance …

A study of factors affecting queen survival, nest initiation, and nest development in the baldfaced hornet Dolichovespula maculata (L.) (Hymenoptera:Vespidae)
… nutrient reserve effects on queen survival and nest initiation were examined with respect to the reproductive fitness of queens of the baldfaced hornet, Dolichovespula maculata. The sperm content of the Spermatheca was examined in queens of this hornet species and in queens of 10 other …

Nest Predation by brown-headed cowbirds (Molothrus ater)
… output, if they cause unsuitable late-stage host nests to fail thereby stimulating the host to create another nest that they can parasitize. I tested key predictions of this ‘farming’ hypothesis for the brown-headed cowbird (Molothrus ater). I found evidence that cowbird attacks are not uncommon, …

Nest agency in the dissemination of global English
… of the role that “native” English speakers (NESTs) play as individual agents in the process of the spread and promotion of the English language. Previous research has examined and critiqued the ideologies that support the spread of English and the agency of those who resist or redefine …

Nest-site selection, nocturnal nest desertion, and productivity in a common tern (<i>sterna hirundo</i>) colony at Detroit River, Michigan
… and vegetation preference and productivity of nesting terns at two scales: general habitat and nest-site. Terns nested later and less successfully in large river rock (13 to 25-cm diameter) compared to more diverse substrate and limestone (2.5-5.0 cm) when it was free of dead vegetation. Within …

Generating Compact Wasp Nest Structures via Minimal Complexity Algorithms.
… building algorithms and characterizes how nests are built using these algorithms. Three rules postulated to be functions of wasps' building behavior were developed. First is the random rule, in which there is no constraint per the choice of site to be initiated. The second is the 2-cell …

Nest-site selection by Sharp-shinned Hawks in Kentucky
… breeding biology, including their preferred nesting habitat. In 2009 and 2010, I searched 248 forest stands in Kentucky and found 11 nests, all located in pines (Pinus spp.). Nests were at a mean height of 18.6 ± 1.4 m in trees with a mean height of 23.7 m and mean dbh of 38.2 cm. Nests were …

Nest Morphogenesis and Population Ecology of Two Species of Formica

Does nest size constrain clutch size? A tropical-temperate test
… time. An untested hypothesis posits that higher nest predation in the tropics favors smaller nests thereby constraining clutch-size. We tested this hypothesis by conducting an experiment to test whether nest predation increases with nest size in a tropical forest. Furthermore, we studied north …

Daily Nest Opening and Closing of the Ant Pogonomyrmex Californicus
… a study of timing in this ant ten of the twelve nests which were observed opened synchronously in the morning and closed in the evening. However, one was never seen to close and another closed during the day and stayed open at night.</p> <p>A seasonal progression was shown by later opening times …

In the Bird's Nest: Birth Orders Influence on the Art
… emerging adults through the use of Kaiser’s bird nest drawing (1996); an art therapy assessment tool in conjunction with Simpson’s Attachment Index (1990). Due to the small sample size (n=45) distributed across three birth orders (oldest/only, middle, youngest) the findings were unable to yield …

An experimental analysis of nest predation in eastern deciduous forests
Nest predation exerts a major influence on the reproductive success of birds because it is the most important cause of nest loss. In this thesis, I studied how richness, density, and frequency of nests, and the fragmentation of forests through alterations of the landscape and forest structure …

Cheating and Selfishness in Reproductive Interactions among Nest Associative Cyprinids
… United States, one fish-fish mutualism is the nest association between Nocomis and other cyprinids. I assessed the role of host parental care while testing for the selfish-herd effect. Additionally, I examined multiple nest associates in order to elucidate potential cheaters. I utilized …

An Evaluation of Duck and Ring-Necked Pheasant Nest Survival and Nest Density in Relation to Patch Size and Landscape Variables in Eastern South Dakota
… patches are hypothesized to experience decreased nest survival rates for ring-necked pheasants (Phasianus colchicus) and dabbling duck species due to small size and high degrees of fragmentation. Several natural resource agencies currently conserve grasslands throughout eastern South Dakota, but …
