Assessment of spatiotemporal trends in groundwater depth and salinity through GIS‐based geostatistical analysis: The case of Aksu Irrigation System in Antalya, Türkiye

open access: yesRiver, EarlyView.
The study revealed that while groundwater depth trends were generally risk‐free, electrical conductivity showed localized risks in 38% of the Aksu Irrigation System. Overall, 25% of the area was classified as risky. The integrated GIS‐based approach provides a rapid, objective, and cost‐effective tool for precision water management. Abstract Continuous

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

open access: yesAnimal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.
