Biodiversity and bird welfare in evaluation of tourism impact and sustainability in arid environment

open access: yesPeople and Nature, EarlyView.
Abstract Nature‐based tourism is rapidly expanding in arid regions, raising concerns about its long‐term sustainability and potential impacts on biodiversity. However, empirical evidence evaluating its effects on both species diversity and animal welfare remains limited.

Mechanically robust biochar‐modified polystyrene foam with enhanced flame retardancy using halogen‐free additives

open access: yesPolymer International, EarlyView.
Halogen‐free biocomposite polystyrene foams were fabricated via pilot‐scale supercritical CO2 extrusion using expandable graphite, melamine polyphosphate, biochar, and recycled polymer. The optimized formulation exhibited refined cellular morphology, enhanced flame retardancy (limiting oxygen index of 25%, rapid self‐extinguishing), and improved ...

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...
