TL;DR: The hyporheic corridor concept describes gradients at the catchment scale, extending to alluvial aquifers kilometers from the main channel as discussed by the authors, which is an active ecotone between the surface stream and groundwater.

TL;DR: This paper identifies 11 relatively independent measures of hydrological variability that help categorize river types and are each associated with aspects of fish biology that enhance the value of the Flood Pulse Concept for river conservation, management and restoration.

TL;DR: In this paper, the effects of droughts on aquatic biota were investigated in English and Australian intermittent streams, and the authors found that the response of aquatic organisms to drought is dependent on the timing and rapidity of hydrological transitions across thresholds, exhibiting a "stepped" response alternating between gradual change while a threshold is approached followed by a swift transition when a habitat disappears or is fragmented.

TL;DR: In this article, the authors developed conceptual models and used simple bivariate plots to visualize human impacts and restoration efforts in terms of connectivity and flow dynamics, and found that human-induced changes in longitudinal, lateral, and vertical connectivity are often accompanied by changes in flow dynamics.

TL;DR: A multidisciplinary approach seeks to elucidate the function of groundwater ecosystems and their roles in maintaining subterranean and surface water quality as discussed by the authors, which will lead to a better understanding of the implications of groundwater hydrology and aquifer geology to distributions of subsurface fauna and microbiota, ecological processes such as carbon cycling, and sustainable groundwater management.
