Emotional vocalizations alter behaviors and neurochemical release into the amygdala

eLife
The basolateral amygdala (BLA), a brain center of emotional expression, contributes to acoustic communication by first interpreting the meaning of social sounds in the context of the listener’s internal state, then organizing the appropriate behavioral ...

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 ...

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

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 ...

Closing Trajectories: Equation‐Free Cyclic Animation via Koopman Surrogates

Computer Graphics Forum, EarlyView.
Abstract Cyclic animation is widely used in computer graphics and interactive content. It supports seamless playback in games, VR, and interactive simulation, where short clips must repeat smoothly over long durations. Converting an observed non‐cyclic trajectory into a seamless loop is challenging because the endpoint states of the observed sequence ...

Transmission of Urgency Levels in the Alarm Calls of the Oriental Reed Warbler

Ecology and Evolution
Many animals communicate predator‐related information to conspecifics through alarm calls that exhibit acoustic structural variations encoding key parameters such as predator type, body size, and urgency of danger.

Peer Pressure: Do the Fitness Benefits of Animal Behavioral Traits Vary With Conspecific Density?

Ethology, EarlyView.
We show that the activity of juvenile North American red squirrels influenced their survival in a density‐dependent manner: more active individuals had higher survival under high conspecific density, whereas less active juveniles had higher survival under low densities. Juveniles who were both more active and aggressive were more likely to survive. Our

Variation in responses to interspecific vocalizations among sister taxa of the Sittidae: imminent extinction of a cryptic species on Grand Bahama Island?

Avian Conservation and Ecology, 2020
We conducted playback-response experiments to assess whether the Brown-headed Nuthatch (Sitta pusilla) population found on Grand Bahama Island might be a distinct and critically endangered species.
