Wild Pigs (Sus scrofa) Stand Their Ground: Investigating Flight Response, or Lack Thereof, to Perceived Predation Risk 野猪坚守原地:探究其面对感知捕食风险时的逃逸反应 (或无逃逸行为)

Wildlife Letters, EarlyView.
We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Fecal Glucocorticoid and Androgen Metabolites in Eastern Grey Kangaroos (Macropus giganteus) Following Environmental Relocation

Zoo Biology, EarlyView.
Fecal glucocorticoid (GCM) and androgen metabolite (AM) concentrations were monitored for 3 months following the relocation of three eastern gray kangaroos (Macropus giganteus) between zoological facilities. Both metabolites showed high concentrations during the early postrelocation period, followed by a rapid decline and stabilization, suggesting ...

Reproductive success under constraints: Does increased maternal activity during lactation offset poor habitat and individual quality in an income breeder?

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐induced environmental modifications may alter forage access and, hence, how animals manage energy trade‐offs during critical periods. Reproduction, especially lactation, is the most energetically costly process for female mammals.

Threat level and sound production mode modulate acoustic warnings and defensive biting in snakes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately assessing predation risk is important because it enables prey to match their defensive behaviours to the level of threat and avoid unnecessary investment in costly responses.

Expression and mechanisms of behavioral plasticity in large mammals

Ecosphere
Behavioral plasticity, the alteration of behavior in response to stimuli, is becoming increasingly important in the context of human‐induced rapid environmental change.

Out of the fire and into the frying pan: Hostile post‐fire thermal conditions reduce activity windows for reptiles

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change and intensified fire regimes are reshaping ecosystems globally. Reptiles, as ectotherms, rely on microhabitat shelters to buffer against thermal extremes, yet the capacity of these shelters to persist or function following fire remains poorly understood ...

Beyond thermoregulation: Active behavioural regulation of ultraviolet light exposure by a free‐ranging lizard

Journal of Animal Ecology, EarlyView.
This study provides a clear demonstration of active ultraviolet (UV) regulation in free‐ranging lizards and supports that microhabitat choice likely constrains UV regulation more than thermoregulation. Overall, it serves to establish UV as a parallel regulatory axis of physiological homeostasis and expand the range of testable hypotheses in animal ...

Contextually conspicuous species are more likely to be venomous: Habitat‐dependent aposematic colouration found throughout snakes

Journal of Animal Ecology, EarlyView.
Conspicuous colouration signals venomous nature throughout snakes. Abstract Many animals use conspicuous colours to advertise their unprofitability to potential predators, a phenomenon known as aposematism. For example, conspicuous banded patterns in snakes are often highlighted as aposematic signalling of their venomous nature.

Thermal adaptation strategies in crustaceans: Potential threats to aquaculture in a warming climate

Aquaculture and Fisheries
Global warming severely challenges aquatic ecosystems and aquaculture, threatening crustacean production through rising temperatures and extreme heat events.
