Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

The rise and fall of a volcanic plateau: Landscape evolution at the fringes of the former Patagonian Ice Sheet, Meseta Chile Chico, central Patagonian Andes

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

open access: yesThe Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Modeling effects of environmental conditions and hunter activity on Montezuma quail harvest in Arizona

open access: yesThe Journal of Wildlife Management, EarlyView.
Models of spatiotemporal variation in hunter harvest show that monsoon precipitation and changes in hunter behavior and composition are the primary drivers underlying variation in annual harvest of Montezuma quail. The demographic structure of the previous year's harvest was also strongly associated with the magnitude and rate of annual harvest ...

Land Degradation Pathways of Open‐Pit and Underground Mining in Karst Regions: A Spatial Indicator Assessment

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Mining in the karst regions of southwest China threatens ecosystem stability and accelerates land degradation. Regional evaluation rarely distinguishes between degradation pathways in open‐pit and underground operations, due to spatial heterogeneity and geomorphological confounding effects.
