Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

Ecography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Designing and evaluation of three alternatives highway routes using the Analytical Hierarchy Process and the least-cost path analysis, application in Sinai Peninsula, Egypt

Egyptian Journal of Remote Sensing and Space Sciences, 2013
Land use planning in a remote desert zone is usually dependent on an efficient corridor and main road network system. In this paper, Geographic Information System (GIS) tools were used to develop a least-cost path for a corridor to link three cities in ...

Extrapolation strategy matters when transferring ecological niche models: new visualization tools for informed decisions

Ecography, EarlyView.
Abstract Ecological niche models (ENMs) are commonly used to predict species' potential distributions across space and time, allowing researchers and practitioners to assess invasion risk, estimate the impacts of future climate change, and reconstruct past distributions.

Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.
