Ram L. Ray, Dionysia Panagoulia, Nimal Abeysingha, editor(s)
2023, Book chapter, River basin management: Under a changing climate
A multiscale perspective is essential for conservation planning of riverine fishes. Coarse-scale habitat (e.g., basis) can influence both finer-scale habitat characteristics (e.g., reaches and microhabitat) and associated species distributions. Finer-scale management and habitat rehabilitation efforts can fail without the consideration of coarser-scale constraints. We provide a conceptual hierarchical framework for...
