Using piecewise regression to identify biological phenomena in biotelemetry datasets Using piecewise regression to identify biological phenomena in biotelemetry datasets
1. Technological advances in the field of animal tracking have greatly expanded the potential to remotely monitor animals, opening the door to exploring how animals shift their behavior over time or respond to external stimuli. A wide variety of animal-borne sensors can provide information on an animal’s location, movement characteristics, external environmental conditions, and internal

Sandhill crane colt survival in Minnesota Sandhill crane colt survival in Minnesota
Age-structured population models require reliable estimates of cohort-specific survival rates, yet vital rates of younger age classes are often difficult to estimate because of the logistical challenges of monitoring young animals. As part of a study of sandhill cranes Antigone canadensis in the zone of contact between breeding distributions of the Eastern Population and Midcontinent...

Patterns of parental care and movement in divided broods of golden-winged warblers Patterns of parental care and movement in divided broods of golden-winged warblers
Post-fledging brood division is a poorly understood, yet widespread suite of avian behaviours that includes both division of parental care and spatial division of a brood. For most species, the differences in parental care between adult males and females and the behavioural mechanisms explaining spatial patterns of brood division are unknown. We studied brood division in golden-winged...

Tallgrass prairie wildlife exposure to spray drift from commonly used soybean insecticides in Midwestern USA Tallgrass prairie wildlife exposure to spray drift from commonly used soybean insecticides in Midwestern USA
Insecticides are widely used in the Midwestern USA to combat soybean aphids (Aphis glycines), a globally important crop pest. Broad-spectrum foliar insecticides such as chlorpyrifos, lambda-cyhalothrin, and bifenthrin (hereafter, “target insecticides”) are toxic to wildlife in laboratory settings; however, little information exists regarding drift and deposition of these insecticides in...

Migration phenology and patterns of American woodcock in central North America derived using satellite telemetry Migration phenology and patterns of American woodcock in central North America derived using satellite telemetry
American woodcock Scolopax minor (hereafter woodcock) migration ecology is poorly understood, but has implications for population ecology and management, especially related to harvest. To describe woodcock migration patterns and phenology, we captured and equipped 73 woodcock with satellite tracking devices in the Central Management Region (analogous to the Mississippi Flyway) of North...
