Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

open access: yesOikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Unravelling vicious circles of land use competition and food insecurity in agropastoral rangelands

open access: yesPeople and Nature, EarlyView.
Abstract In many regions of the world, the adoption of new livelihood strategies that compete with traditional strategies is one driver of competition over land, resulting in unforeseen impacts on the livelihoods of land users and accelerating land degradation. One example is the Borana Zone in southern Ethiopia, where the expansion of crop cultivation

Doubling CO2 Modulates Root Morphology to Enhance Maize Elemental Stoichiometry and Water Use Efficiency Under Soil Drought and Salinity

open access: yesAgronomy
This study aimed to explore the effect of doubled CO2 concentration (d[CO2]) on the modulation of root morphological structure, leaf potassium (K)/sodium (Na) ratio, and nutrient stoichiometry, as well as water use efficiency (WUE) of a C4 maize (Zea ...

Effects of Surface Characteristics on the Existence of Isolated Permafrost in Northeastern Mongolia

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Isolated patches of permafrost, where ground thermal changes are affected by ecosystem factors such as vegetation cover rather than climate, may be vulnerable to environmental disturbances in semiarid regions. However, the impacts of ecosystem factors remain underevaluated in Mongolia.

Drought Reduces Formation, but Enhances Persistence, of Mineral-Associated Organic Matter in a Grassland Soil. [PDF]

open access: yesGlob Chang Biol
We used a 13C‐CO2 labeling study to track the formation and persistence of mineral‐associated soil carbon derived from living root and decaying root inputs under normal moisture and droughted conditions in a semiarid grassland soil. Drought reduced the formation of MAOM derived from living roots by decreasing rhizodeposits, reducing microbial growth ...

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.
