Snake activity affects seasonal variation in nest predation risk for birds
TLDR
The results indicate that variation in predator behavior can be associated with and potentially cause seasonal changes in nest success, but also that these relationships are species specific even within the same community and may depend on aspects of the nesting ecology of the prey such as nest site selection. Expand
Is Nest Predation on Two Endangered Bird Species Higher in Habitats Preferred by Snakes?
TLDR
It is suggested that warbler nests were at greater risk if edge was abundant near the nest, and reducing edge could promote nest survival, because ratsnakes preferred warbler habitat over vireo habitat, vireos might suffer less predation in larger habitat patches that would increase average distances from the snakes' preferred habitat. Expand
Latitudinal variation in thermal ecology of North American ratsnakes and its implications for the effect of climate warming on snakes
TLDR
Ratsnakes in Texas switch to nocturnal activity during summer, whereas in Illinois and Ontario activity is exclusively diurnal and hibernation lasts 5–7 months, and modeling indicated that a 3 °C increase in ambient temperature will generally improve thermal conditions for all three populations. Expand
Effects of parasitic infection and radio-transmitters on condition, hematological characteristics and corticosterone concentrations in Texas ratsnakes
TLDR
The results generally support the view that data collected using radio-telemetry are unlikely to be biased due to adverse health effects of transmitters, and the growing importance of telemetry for studies of snakes and other taxa argues for further research on this topic. Expand
Evaluation of Automated Radio Telemetry for Quantifying Movements and Home Ranges of Snakes
TLDR
An automated telemetry system that can dramatically increase the amount of activity and spatial data collected for snakes, and Automated receivers can increase data greatly from radio-tracked snakes, providing novel insights unavailable from conventional hand tracking is evaluated. Expand
Use of chorus sounds for location of breeding habitat in 2 species of anuran amphibians
TLDR
This study provides some of the first experimental field evidence that anurans use conspecific cues to locate new breeding habitat; however, species with certain life-history traits may be more likely to exhibit this behavior. Expand
Does Prey Availability Determine Seasonal Patterns of Habitat Selection in Texas Ratsnakes
TLDR
Test the hypothesis that Texas Ratsnakes choose habitats based on prey availability during their active season and on cover during winter and results provide limited support for the hypothesis but do indicate that ratsnakes select winter habitat based on cover availability. Expand
Sex differences in behavior associated with sex‐biased mortality in an oviparous snake species
TLDR
Radio-telemetry examination of sex-biased mortality in Texas ratsnakes Elaphe obsoleta suggests the cost of reproduction is greatest following egg laying, similar to what has been found for females of viviparous species. Expand
Power lines, roads, and avian nest survival: effects on predator identity and predation intensity
TLDR
Predicting how anthropogenic changes to landscapes affect nesting birds requires that more is known about how landscape changes affect the behavior of nest predators and which nest predators are locally important. Expand
Nest Predators of North American Birds: Continental Patterns and Implications
TLDR
Overall, mesopredators and snakes were the most frequent nest-predator guilds and Predator richness was greatest at midlatitudes but was a poor predictor of predation probability, and nest height and habitat influenced predator-specific predation. Expand
