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

Royal 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

Animal 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 ...

Smelling out predators is innate in birds [PDF]

, 2011
The role of olfaction for predation risk assessment remains barely explored in birds, although predator chemical cues could be useful in predator detection under low visibility conditions for many bird species.

SEXUAL PREDATORS

Psychiatric 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

Biology 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

Ecology 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

Persian 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.

Tearing Out the Income Tax by the (Grass)Roots [PDF]

, 2011
Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e.

Predation risk reduces a female preference for heterospecific males in the green swordtail [PDF]

, 2016
The presence of a predator can result in the alteration, loss or reversal of a mating preference. Under predation risk, females often change their initial preference for conspicuous males, favouring less flashy males to reduce the risk of being detected ...

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?

Ecology 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 ...
