TL;DR: The ecological limits of hydrologic alteration (ELOHA) as mentioned in this paper is a framework for assessing environmental flow needs for many streams and rivers simultaneously to foster development and implementation of environmental flow standards at the regional scale.
Journal ArticleDOI
Ecological and evolutionary consequences of biotic homogenization.
TL;DR: The goal is to initiate future research that investigates the broader conservation implications of homogenization and to promote a proactive style of adaptive management that engages the human component of the anthropogenic blender that is currently mixing the biota on Earth.
Journal ArticleDOI
Emerging threats and persistent conservation challenges for freshwater biodiversity
Andrea J. Reid,Andrew K. Carlson,Irena F. Creed,Erika J. Eliason,Peter Gell,Pieter T. J. Johnson,Karen A. Kidd,Tyson J. MacCormack,Julian D. Olden,Steve J. Ormerod,John P. Smol,William W. Taylor,Klement Tockner,Jesse C. Vermaire,David Dudgeon,Steven J. Cooke +15 more
TL;DR: Efforts to reverse global trends in freshwater degradation now depend on bridging an immense gap between the aspirations of conservation biologists and the accelerating rate of species endangerment.
Journal ArticleDOI
Homogenization of regional river dynamics by dams and global biodiversity implications.
TL;DR: Long-term streamflow records are used on intermediate-sized rivers across the continental United States to show that dams have homogenized the flow regimes on third- through seventh-order rivers in 16 historically distinctive hydrologic regions over the course of the 20th century.

TL;DR: A comprehensive assessment of the world’s rivers and their connectivity shows that only 37 per cent of rivers longer than 1,000 kilometres remain free-flowing over their entire length.
