ADVANCED TECHNIQUES FOR MODELING AVIAN NEST SURVIVAL
Ecology, 2002Estimation of avian nest survival has traditionally involved simple measures of apparent nest survival or Mayfield constant-nest-survival models. However, these methods do not allow researchers to build models that rigorously assess the importance of a wide range of biological factors that affect nest survival.

Effects of Mesopredators on Nest Survival of Shrub‐Nesting Songbirds
The Journal of Wildlife Management, 2010ABSTRACT Although nest predation is often the single largest source of mortality in avian populations, manipulative studies to determine predator impacts on nest survival are rare, particularly studies that examine impacts of mid‐size mammalian predators (hereafter, mesopredators) on nest survival of shrub ...

Early nest initiation and vegetation density enhance nest survival in Wild Turkeys
Ornithology, 2022Abstract The theory of adaptive habitat selection suggests resource selection by animals should reflect underlying quality, such that individual selection confers an adaptive advantage via increased fitness. Using resource selection functions and nest survival models, we demonstrated that visual obstruction at the nest site was ...

Merriam's Turkey Nest Survival and Factors Affecting Nest Predation by Mammals
The Journal of Wildlife Management, 2008Abstract: Nest success is an important parameter affecting population fluctuations of wild turkeys ( Meleagris gallopavo ). Factors influencing mammalian predation on turkey nests are complicated and not well understood.

Nest predators, but not nest survival, differ between adjacent urban habitats
Urban Ecosystems, 2018Growing human populations make it imperative for ecologists to identify strategies to conserve biodiversity in human-dominated landscapes, such as cities. Effects of urbanization on birds are particularly well-studied, but questions remain regarding the best conservation approaches.

Predation on painted turtle nests: nest survival as a function of nest age
Canadian Journal of Zoology, 1982This study examined the relationship between nest age and predation rate in painted turtles (Chrysemys picta). Eighty-one intact nests were found; 33 were eventually preyed upon during the study. New nests (less than 72 h old) do not appear to have a greater risk of predation than older nests. The majority (55%) of nests preyed upon were older than 72

Adaptive nest clustering and density‐dependent nest survival in dabbling ducks
Oikos, 2013Density‐dependent population regulation is observed in many taxa, and understanding the mechanisms that generate density dependence is especially important for the conservation of heavily‐managed species. In one such system, North American waterfowl, density dependence is often observed at continental scales, and nest predation has long been implicated

Factors Influencing Nest Survival in Florida Bass
Transactions of the American Fisheries Society, 2017AbstractAngling nesting Florida Bass Micropterus salmoides floridanus may influence the survival of the brood and could negatively affect bass populations. Our objectives were to estimate daily nest survival for Florida Bass and to examine factors that influence nest survival to the swim‐up fry stage. Snorkelers examined a total of 259 nests in a small,

The Auk, 2008
Abstract The disturbance associated with nest monitoring raises concerns about the validity of the estimated nest success and the well-being of the populations under study. Observer activity may attract or deter predators to or from bird nests, thus decreasing or increasing nest success.

Bayesian hierarchical models for estimating nest survival
2021[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI 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.
