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.

Sexual selection for both diversity and repetition in birdsong

Nature Communications, 2023
From fiddler crabs to humans, animals perform repetitive displays showing neuromotor skill and vigour. Consistent repetition of identical notes (vocal consistency) facilitates the assessment of neuromotor skills and is important in communication in birds.

Finding Mr. Right: Housing Quality Affects Male Mouse Attractiveness to Females, With Implications for Conservation Captive Breeding

Zoo Biology, EarlyView.
Housing quality affects male mouse attractiveness to females ABSTRACT Females generally prefer mates with traits indicating low stress (e.g., large size; good health). In captivity, stress from suboptimal housing might therefore reduce male attractiveness.

Playback Experiments

, 2017
Field playback experiments are a powerful way to tap into nonhuman primates' communication and cognition in their natural environment. From the animals' responses, researchers can infer how animals categorize and respond to different sounds, while controlling for other available information.

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

Journal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

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 ...

See4D: Pose‐Free 4D Generation via Auto‐Regressive Video Inpainting

Computer Graphics Forum, EarlyView.
Abstract Immersive applications call for synthesizing spatiotemporal 4D content from casual videos without costly 3D supervision. Existing video‐to‐4D methods typically rely on manually annotated camera poses, which are labor‐intensive and brittle for in‐the‐wild footage.

UrbanClipAtlas: A Visual Analytics Framework for Event and Scene Retrieval in Urban Videos

Computer Graphics Forum, EarlyView.
Abstract Extracting actionable insights from long‐duration urban videos is often labor‐intensive: analysts must manually sift through raw footage to pinpoint target events or uncover broader behavioral trends. In this work, we present UrbanClipAtlas, a visual analytics system for exploring long urban videos recorded at street intersections ...

Startling ravens Corvus corax at foraging: differences in anti‐predator behaviour can be explained by age rather than personality

Journal of Avian Biology
When individuals of the same population do not respond uniformly to the same situation, they might experience divergent fitness outcomes, such as different survival rates when facing danger.

Exposure to calls before hatching affects the post-hatching behaviour of domestic chickens

Royal Society Open Science
The soundscape experienced by animals early in life can affect their behaviour later in life. For birds, sounds experienced in the egg can influence how individuals learn to respond to specific calls post-hatching. However, how early acoustic experiences
