Ecohydrology, Volume 17, Issue 8, December 2024.Abstract Environmental flows (e‐flows) assessments are a powerful mechanism for enhancing and conserving the ecosystem goods and services rivers provide while allocating water to essential human use. There is a paucity of e‐flows assessments and implementation in water scarce regions such as the Middle East, where limited freshwater resources are under

Life History of an Endangered Marine Insect Halovelia septentrionalis Esaki (Hemiptera: Veliidae)
Psyche: A Journal of Entomology, 2015 Halovelia septentrionalis Esaki is one of the endangered marine water striders found along the Japanese coast. It is of primary importance to investigate its life history in the field so as to develop conservation measures as well as to understand how ...

Description of Some Indian Veliidae in Different Zoogeographical Regions with Special Emphasis on Rhagovelia and Microvelia [PDF]
, 2017 The knowledge regarding the Veliidae fauna of India through at the moment is far from complete, but we can profitably venture on an analysis of the zoogeographical composition of the fauna on the basis of present study which should be fairly an accurate ...

Dry season refuges, refugia and flow‐regime change in Mediterranean climate streams
Freshwater Biology, Volume 69, Issue 11, Page 1607-1626, November 2024.Abstract Climate change is causing stream flow regimes to change in many regions globally, including southwestern Australia (SWA) where many perennial streams have switched to intermittent flow regimes. In drier landscapes, ecological refuges and evolutionary refugia will become critical for conserving freshwater biodiversity.

Ecohydrology, Volume 17, Issue 5, July 2024.Abstract Impacts of metal pollution, either on water or in sediments within aquatic systems have been a serious challenge globally. Little is known about the ecological impacts of metal pollution on benthic macroinvertebrates species in sub–tropical river systems.

Similarity of stream insect trait profiles across biogeographic regions
Diversity and Distributions, Volume 30, Issue 4, April 2024.Abstract Aim Habitat templet theory predicts that the functional niches of species evolved in response to selection pressures imposed by each species' spatial–temporal environment. Consequently, similar environmental conditions should lead to convergence in the biological trait composition of biogeographically independent assemblages.
