Spatial Ecology and Habitat Use in Snake Populations

Spatial ecology and habitat use in snake populations encompass the study of how snakes interact with their environment across multiple scales, from microhabitats to landscape mosaics. Research has highlighted that individual home ranges vary widely, influenced by thermoregulatory needs, prey distribution and reproductive strategies. Landscape features such as vegetation structure, water bodies and human‐modified matrices shape movement patterns, resource selection and interspecific interactions. Climate change, land-use alteration and habitat fragmentation are altering thermal landscapes and refugia, driving range shifts, contractions and shifts in niche expression. Studies now combine radiotelemetry, remote sensing and ecological modelling to predict current and future distributions, identify critical corridors and design protected-area networks. The global significance of this work lies in informing conservation actions under rapid environmental change, from maintaining connectivity in agricultural regions to redesigning reserve networks in biodiversity hotspots.

Recent studies have examined niche expression and range dynamics under shifting environmental conditions. Analyses of contact zones between two viper species across varied Iberian landscapes revealed that abiotic and biotic factors drive asymmetrical niche variation, with generalist species expanding under anthropogenic disturbance and specialists retreating. This work highlights how local landscape alteration can intensify competition and alter coexistence patterns. In a major biodiversity hotspot, projections of climatically suitable areas for Atlantic Forest snakes predict drastic range contractions under warming scenarios, with oviparous species particularly vulnerable. Existing protected areas were shown to offer limited refugia, prompting calls for the redesign of reserve networks to maximise species persistence under future climates.

Thermal landscape: The spatial variation in temperature across a habitat, influencing ectotherm behaviour and physiology.

Contact zone: A geographic region where the distributions of two closely related species meet and potentially interact.
