Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

Integrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

Fragment Edges Benefit a Common Predator of Pollinators via Bottom‐Up Effects

Integrative Zoology, EarlyView.
This study investigated the hypotheses regarding the effects of habitat fragmentation on spider biomass and causing bottom‐up or top‐down effects on multi‐trophic relationships. ABSTRACT Defaunation following habitat fragmentation typically threatens predators at higher trophic levels, which further alter prey and plants via top‐down effects.

Dilemmas of Civilian Participation in Military Deterrence and Defence: Legal and Ethical Dimensions

Global Policy, EarlyView.
ABSTRACT How can civilians participate in deterrence and defence in ways that do not jeopardize their immunity from deliberate attack? The principle of civilian immunity from deliberate attack in war is a core element of contemporary international humanitarian law (IHL). Uniformed combatants and others who take up arms pose a threat may be liable to be

Rise of the south: How Arab‐led maritime trade transformed China, 671–1371 CE

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 3-38, March 2025.
Abstract China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re‐creating the South.

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

Archaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the
