Sharp Force Trauma and Chop Mark Identification Bias: Experimental Evidence on the Effects of Bone Morphology, Cortical Thickness, and Ax Material

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Sharp force trauma (SFT) is the main criterion used to identify chop mark butchery in zooarchaeology, yet its reliability as a diagnostic feature has not been systematically tested. Chop marks reflect both cutting and fracturing processes and exhibit characteristics of both sharp and blunt trauma.

Hidden Insights: Comprehensive Radiological Analysis of Four Skeletal Populations From 13th–19th Century Southern Finland Reveals Neoplastic and Other Lesions Invisible on Bone Surfaces

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study aims to identify lesions confined to the internal structures of bones. A radiographic analysis was performed on 219 archaeological, historical period skeletons from southern Finland. Although the study examines nearly all preserved skeletal elements using plain radiographs, it does not incorporate computed tomography.

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

Oikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.
