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

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.

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 ...

Morphometry of the reproductive system of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera, Pentatomidae) when submitted to different temperatures [PDF]

open access: yesCiência Rural, 2020
: In order to manipulate the mass rearing of natural enemies, temperature variations can be used. The effects are widely studied for their survival and developmental duration; however, there is little information about their reproductive system in the ...

Energy cost and return for hunting in African wild dogs and cheetahs

open access: yesNature Communications, 2016
The long-distance hunting behaviour of African wild dogs is thought to be energetically costly. Here, Hubel et al. show that multiple opportunistic short-distance hunts and group feeding make African wild dogs in mixed woodland savannah energetically ...

Fear of predators alters herbivore regulation of soil microbial community function

open access: yesEcology and Evolution, 2023
Fear of predation can affect important ecosystem processes by altering the prey traits expression that, in turn, regulates the quantity and quality of nutritional inputs to soil.
