Warming temperatures increase close encounters between two top predator species via changes in spatial behaviour [PDF]

Movement Ecology
Effectively responding to changing environmental and ecological conditions, such as changing climatic conditions, is crucial for individual survival, population dynamics, and ecosystem structuring.

Using accelerometers to develop time-energy budgets of wild fur seals from captive surrogates [PDF]

PeerJ, 2018
Background Accurate time-energy budgets summarise an animal’s energy expenditure in a given environment, and are potentially a sensitive indicator of how an animal responds to changing resources. Deriving accurate time-energy budgets requires an estimate

Drone Observations of Marine Life and Human–Wildlife Interactions off Sydney, Australia

Drones, 2022
Drones have become popular with the general public for viewing and filming marine life. One amateur enthusiast platform, DroneSharkApp, films marine life in the waters off Sydney, Australia year-round and posts their observations on social media.

Anthropogenic edge effects and aging errors by hunters can affect the sustainability of lion trophy hunting

Scientific Reports, 2023
Many large predator populations are in decline globally with significant implications for ecosystem integrity and function. Understanding the drivers of their decline is required to adequately mitigate threats.

Geographical, temporal, and individual‐based differences in the trophic ecology of female Cape fur seals

Ecology and Evolution, 2023
Information on resource use and trophic dynamics of marine predators is important for understanding their role in ecosystem functioning and predicting population‐level responses to environmental change.

A critical assessment of marine predator isoscapes within the southern Indian Ocean

Movement Ecology, 2020
Background Precise and accurate retrospective geolocation of marine predators via their tissues’ isotopic composition relies on quality reference maps of relevant isotopic gradients (“isoscapes”).

Super machine learning: improving accuracy and reducing variance of behaviour classification from accelerometry

Animal Biotelemetry, 2017
Background Semi-automating the analyses of accelerometry data makes it possible to synthesize large data sets. However, when constructing activity budgets from accelerometry data, there are many methods to extract, analyse and report data and results ...

Wildlife responses to livestock guard dogs and domestic sheep on open range

Global Ecology and Conservation, 2021
Domestic sheep (Ovis aries) are an attractant to carnivores; however, sheep are often accompanied by humans and livestock guardian dogs (LGDs; Canis familiaris), which defend sheep from depredation.

The effect of relatedness and pack size on territory overlap in African wild dogs

Movement Ecology, 2017
Background Spacing patterns mediate competitive interactions between conspecifics, ultimately increasing fitness. The degree of territorial overlap between neighbouring African wild dog (Lycaon pictus) packs varies greatly, yet the role of factors ...

Intolerant baboons avoid observer proximity, creating biased inter-individual association patterns

Scientific Reports, 2022
Social network analysis is an increasingly popular tool for behavioural ecologists exploring the social organisation of animal populations. Such analyses require data on inter-individual association patterns, which in wild populations are often collected
