Cortisol concentrations in hair are biomarkers of health status and seasonal change, but not urbanisation, in wolves

Wildlife Biology, EarlyView.
Wolves have reclaimed much of their former range in Europe, including areas with a high human footprint, yet the physiological impacts of human‐associated stressors remain poorly understood. We first examined methodological factors affecting hair cortisol concentrations (HCC) in wolves by using a ‘shave/re‐shave' design to assess hair growth rate and ...

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.

Developing a low‐cost drone‐based method for deploying and retrieving autonomous recording units in inaccessible areas

Wildlife Society Bulletin, EarlyView.
Autonomous recording units (ARUs) are increasingly used for passive acoustic monitoring, but deploying them in remote or inaccessible locations remains challenging. We developed and field‐tested a lightweight, low‐cost floating platform for drone‐assisted deployment and retrieval of ARUs in wetland interiors.

Three sympatric host nestlings eavesdrop on cuckoo nestling distress calls

Ecology and Evolution
In predator–prey interactions, the prey faces extreme challenges from predation, which drives the evolution of defense or anti‐predator mechanisms. Compared with adult birds, nestlings are more vulnerable but not helpless.

Early singers attend to conspecific but not heterospecific behavioural cues at dawn

Journal of Avian Biology, 2018
During the dawn chorus songbirds initiate singing activities just prior to sunrise. Environmental factors affect the timing of the dawn chorus, but relatively little is known about how behavioural cues influence chorus timing.

Weekend Overload: Day‐to‐Day Fluctuations of Outdoor Recreation Affect Wild Mammals' Space‐Use in a Popular Forest Reserve Near Florence, Italy

Animal Conservation, EarlyView.
In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction

Animal Conservation, EarlyView.
Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.

Comparing time‐lapse photography and traditional human observation in collecting crop pollinator visitation data Ajastetun valokuvauksen ja perinteisen suoran havainnoinnin vertailu kerättäessä tietoa pölyttäjien kukkakäynneistä viljelykasveilla

Agricultural and Forest Entomology, EarlyView.
Time‐lapse photography with commercially available trail cameras provides a competitive alternative to direct human observations for documenting pollinator flower visits, but its performance varies between crops. In apple, the cameras recorded more diverse pollinator assemblages than the human observer due to larger temporal coverage of the camera ...
