Anthropological, Pathological, and Historical Analyses of a Mummified Cranium From Bolivia Hosted in the Museum of Cantonal Archaeology and History of Lausanne, Switzerland

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The past decade has seen a worldwide tendency to re‐examine human remains found in old museum collections. These studies look at the provenance of the remains, the way they ended up in specific collections, the context from which they are likely issued, and all the parameters implicated in their current presence in museum custody.

Ectomycorrhizal fungi and root water uptake respond independently to water availability

open access: yesOikos, EarlyView.
Temperate forests on their warm and dry distribution limits are expected to be most vulnerable to reductions in water availability. This prediction is mostly based on studies assessing single forest functions, mainly growth. Water and nutrient cycling are functions that rely on tree roots and their symbiotic association with ectomycorrhizal (ECM) fungi.

Volcanic soils alleviate the allelopathic capacity of Empetrum nigrum in degraded tundra ecosystems

open access: yesOikos, EarlyView.
Land degradation due to unsustainable land use is of major concern worldwide and recovery is often slow. A potential mechanism behind slow recovery of degraded ecosystems is the retarding impacts of allelopathic plant species on the establishment of species that might facilitate the recovery process.

National Park Service staff perspectives on how climate change affects visitor use

open access: yesPeople and Nature, EarlyView.
Abstract Many public lands, including those managed by the U.S. National Park Service (NPS), have the purpose of conserving natural and cultural resources and providing opportunities for visitors to recreate in and enjoy these areas. Achieving this mission becomes more challenging as drought, flooding, increasing temperatures and other climatic change ...

Cryptic Ice Wedge Networks in Holocene Peat, Yukon‐Kuskokwim Delta, Alaska

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The Yukon‐Kuskokwim Delta (YKD), covering ~75,000 km2 of Alaska's discontinuous permafrost zone, has a historic (1902–2023) mean annual air temperature of ~−1°C and was previously thought to lack ice wedge networks. However, our recent investigations near Bethel, Alaska, revealed numerous near‐surface ice wedges.
