Imputation Approaches for Animal Movement Modeling

open access: yes, 2017
The analysis of telemetry data is common in animal ecological studies. While the collection of telemetry data for individual animals has improved dramatically, the methods to properly account for inherent uncertainties (e.g., measurement error ...

Dedicated hippocampal inhibitory networks for locomotion and immobility [PDF]

open access: yes, 2017
Network activity is strongly tied to animal movement; however, hippocampal circuits selectively engaged during locomotion or immobility remain poorly characterized.

Accelerometer‐informed GPS telemetry: Reducing the trade‐off between resolution and longevity

open access: yesWildlife Society Bulletin, 2012
Tracking animal movement using Global Positioning System (GPS) technology is an increasingly popular method for studying animal ecology, behavior, and conservation. To date, most GPS location schedules have been set at regular intervals. If intervals are

Estimating the proportion of a beluga population using specific areas from connectivity patterns and abundance indices

open access: yesEcosphere, 2021
An understanding of habitat use and connectivity is key to preserving wildlife habitat integrity. In this study, we present an innovative approach to habitat connectivity and quantitative assessment of their use that is applicable to any terrestrial or ...

Infrasound as a Cue for Seabird Navigation

open access: yesFrontiers in Ecology and Evolution, 2021
Seabirds are amongst the most mobile of all animal species and spend large amounts of their lives at sea. They cross vast areas of ocean that appear superficially featureless, and our understanding of the mechanisms that they use for navigation remains ...

Recognize the Little Ones: UAS-Based In-Situ Fluorescent Tracer Detection

open access: yesDrones, 2019
In ecological research, a key interest is to explore movement patterns of individual organisms across different spatial scales as one driver of biotic interactions.

Heart-rate pulse-shift detector [PDF]

open access: yes, 1974
Detector circuit accurately separates and counts phase-shift pulses over wide range of basic pulse-rate frequency, and also provides reasonable representation of full repetitive EKG waveform.

State-space models' dirty little secrets: even simple linear Gaussian models can have estimation problems [PDF]

open access: yes, 2016
State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often structured to account for two levels of variability: biological stochasticity ...

Variability in nomadism: environmental gradients modulate the movement behaviors of dryland ungulates

open access: yesEcosphere, 2019
Studying nomadic animal movement across species and ecosystems is essential for better understanding variability in nomadism. In arid environments, unpredictable changes in water and forage resources are known drivers of nomadic movements.

Linking behavioral states to landscape features for improved conservation management

open access: yesEcology and Evolution, 2021
A central theme for conservation is understanding how animals differentially use, and are affected by change in, the landscapes they inhabit. However, it has been challenging to develop conservation schemes for habitat‐specific behaviors.
