Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

Integrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Goby gummies: A customizable and edible assay to quantify predation in aquatic ecosystems

Methods in Ecology and Evolution, EarlyView.
Abstract Predation is a critical ecosystem process that shapes the structure and functioning of biological communities. However, due to its intermittent nature, fast pace and general unpredictability, predation is difficult to observe and quantify. Therefore, we commonly rely on indirect metrics or proxies of predation, which reflect the outcome of ...

UBVH: Unified Bounding Volume and Scene Geometry Representation for Ray Tracing

Computer Graphics Forum, EarlyView.
Abstract Bounding volume hierarchies (BVHs) are currently the most common data structure used to accelerate ray tracing. The existing BVH methods distinguish between the bounding volume representation associated with the interior BVH nodes and the scene geometry representation associated with leaf nodes.

Encoding Occupancy in Memory Location for Efficient and Compact High‐Resolution Voxel Structures

Computer Graphics Forum, EarlyView.
We encode information about geometric structure into the pointers of a sparse voxel directed acyclic graph (SVDAG). Each pointer carries information about the structure of the node it points to. Our encoding improves ray tracing performance and reduces model size in memory.

Robo‐Saber: Generating and Simulating Virtual Reality Players

Computer Graphics Forum, EarlyView.
Abstract We present the first motion generation system for playtesting virtual reality (VR) games. Our player model generates VR headset and handheld controller movements from in‐game object arrangements, guided by style reference gameplay examples. We train on the large BOXRR‐23 dataset and apply our framework on the popular VR game Beat Saber.

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...
