Intrinsic and extrinsic factors drive ontogeny of early-life at-sea behaviour in a marine top predator [PDF]

open access: yes, 2017
Young animals must learn to forage effectively to survive the transition from parental provisioning to independent feeding. Rapid development of successful foraging strategies is particularly important for capital breeders that do not receive parental ...

Snowmelt progression drives habitat selection and vegetation disturbance by an Arctic avian herbivore

open access: yesEcosphere, 2023
Arctic tundra vegetation is affected by rapid climatic change and fluctuating herbivore population sizes. Broad‐billed geese, after their arrival in spring, feed intensively on belowground rhizomes, thereby disturbing soil, mosses, and vascular plant ...

Performance evaluation of GPS telemetry for a middle-small mammal

open access: yesTheory and Applications of GIS, 2004
We evaluated the success rate and accuracy of GPS collar telemetry on a free ranging Japanese monkey (Macaca fuscata). Total success rate was 39.7%, and higher in daytime than nighttime. At nighttime, the monkey was resting in the forest. The weakness of GPS signals and deterioration of ephemeris data in the forest environment may have led to the low ...

A low-cost GPS GSM/GPRS telemetry system: performance in stationary field tests and preliminary data on wild otters (Lutra lutra).

open access: yesPLoS ONE, 2012
BackgroundDespite the increasing worldwide use of global positioning system (GPS) telemetry in wildlife research, it has never been tested on any freshwater diving animal or in the peculiar conditions of the riparian habitat, despite this latter being ...

Design of an underwater telemetry antenna for locating and retrieving submerged radiocollars

open access: yesWildlife Society Bulletin, 2011
Radiocollars represent a significant investment of financial resources, particularly global positioning system (GPS) collars, and loss of data imposes analytical limitations from reduced sample sizes. Radiocollars on large, terrestrial mammals are seldom

Overview of Current Research on Wolves in Russia

open access: yesFrontiers in Ecology and Evolution, 2022
This paper provides an overview of wolf research in Russia at the beginning of the 21st century. Wolf research covered various directions, including population density estimation, management methods and minimization of human-wildlife conflicts, general ...

Camera trapping as a method for estimating abundance of Mexican wolves

open access: yesWildlife Society Bulletin, 2023
Estimating wildlife abundance, particularly for rare and elusive species, is challenging because of time, cost, and methodological constraints. The Mexican wolf (Canis lupus baileyi), a federally‐listed endangered subspecies of gray wolf, is currently ...

Spatial metrics in fire ecology: seeking consistency amidst complexity

open access: yesBiological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Developing a data‐transfer model for a novel Wildlife‐tracking network

open access: yesWildlife Society Bulletin, 2012
The use of low‐cost, advanced global positioning system (GPS) telemetry devices for wildlife tracking is growing in popularity, especially use of systems that can communicate with each other to track contacts or transfer data.

Attacked from two fronts: Interactive effects of anthropogenic and biotic disturbances generate complex movement patterns

open access: yesArctic, Antarctic, and Alpine Research, 2020
Anthropogenic and biotic disturbances have the potential to interact, generating cumulative impacts on animal movement or, alternatively, counterbalancing or masking each other.
