Using environmental flows to inform integrated water resource management in critically water scarce regions

open access: yesEcohydrology, 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

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
Constant evolution rates, which form the foundation of the strict molecular clock model, do not apply in the case of Paleoptera, highlighting a notable bias in the molecular clock hypothesis. The current biodiversity may be the outcome of a relatively recent, exponential increase in base substitution rates.
