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

open access: yesScientific 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

Foraging behaviour and habitat-use drives niche segregation in sibling seabird species

open access: yesRoyal Society Open Science, 2020
To mediate competition, similar sympatric species are assumed to use different resources, or the same but geographically separated resources. The two giant petrels (Macronectes spp.) are intriguing in that they are morphologically similar seabirds with ...

Animal-borne acoustic data alone can provide high accuracy classification of activity budgets

open access: yesAnimal Biotelemetry, 2021
Background Studies on animal behaviour often involve the quantification of the occurrence and duration of various activities. When direct observations are challenging (e.g., at night, in a burrow, at sea), animal-borne devices can be used to remotely ...

SEXUAL PREDATORS

open access: yesPsychiatric Clinics of North America, 1999
Social responses to sex-offending behaviors have included criminal sanctions and clinical interventions that have evolved over time. These developments have created various challenges for mental health professionals charged with providing care to offenders, particularly when legislative expectations have exceeded available treatments.

The utility of accelerometers to predict stroke rate in captive fur seals and sea lions

open access: yesBiology Open, 2017
The energy expenditure of free-living fur seals and sea lions is difficult to measure directly, but may be indirectly derived from flipper stroke rate. We filmed 10 captive otariids swimming with accelerometers either attached to a harness (Daily Diary ...

Foraging in a dynamic environment: Response of four sympatric sub‐Antarctic albatross species to interannual environmental variability

open access: yesEcology and Evolution, 2020
Seasonal and annual climate variations are linked to fluctuations in the abundance and distribution of resources, posing a significant challenge to animals that need to adjust their foraging behavior accordingly.

Vertical extratification of phytophagous and predator mites (Acari) on Caryocar brasiliense (Caryocaraceae) tree canopies

open access: yesPersian Journal of Acarology, 2021
The distribution of Caryocar brasiliense Camb. (Caryocaraceae) trees is wide in the Brazilian Cerrado biome and its fruits are used by humans for food and as the main income source of many communities.

Consistency in the flight and visual orientation distances of habituated chacma baboons after an observed leopard predation. Do flight initiation distance methods always measure perceived predation risk?

open access: yesEcology and Evolution, 2021
Flight initiation distance (FID) procedures are used to assess the risk perception animals have for threats (e.g., natural predators, hunters), but it is unclear whether these assessments remain meaningful if animals have habituated to certain human ...
