Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park

open access: yesThe Journal of Wildlife Management, EarlyView.
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

Impacts of Climate Change on Food Security: Land Management–Based Strategies Within a Nature‐Based Solutions Framework

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Climate change poses serious threats to food security by affecting agricultural production processes in multiple ways. This study aims to analyze land management–based solution strategies that can be developed in response to this threat and presents a systematic and holistic framework through the relationship these strategies establish with ...

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

open access: yesOikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

open access: yesOikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.
