Exploring the phylogenetic history of water striders (Hemiptera: Heteroptera: Gerromorpha) using genome‐skimming

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Using genome‐skimming, we provide a robust and comprehensive phylogeny of the Gerridae. Our data support the monophyly of all subfamilies except paraphyletic Gerrinae. Non‐monophyly was found for Gerrini, Metrobatini and Trepobatini. Additionally, we reaffirm the non‐monophyly of the genera Aquarius and Tenagogonus, both part of the Gerrinae.

Role of Hydrology, Aquatic Vegetation, Habitat Size and Connectivity in Shaping Food Webs in a Eutrophic Agricultural Marshland

open access: yesDiversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Understanding food‐web responses to environmental gradients is crucial for guiding effective ecosystem management measures. This aspect remains understudied in wetlands, particularly in human‐managed marshlands, despite the fact that many environmental factors can be controlled.

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

Spatiotemporal assessment of benthic macroinvertebrate communities in the Bermejo River Basin in the Ecuadorian Amazonia

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 3, Page 371-380, June 2025.
Abstract The Cofán communities rely on the Cofán Bermejo Ecological Reserve for their survival and cultural practices. Due to the rugged and inaccessible topography of the reserve in the Northern Ecuadorian Amazon region, limited biomonitoring and ecological characterization studies of the ecosystem health have been conducted.

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
