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.

Rhagoveliaspecies from Nosy Boraha east of Madagascar (Hemiptera: Heteroptera: Veliidae) [PDF]

open access: yesActa Entomologica Musei Nationalis Pragae, 2020
In the years 1992 and 1993, the Austrian entomologist Michael Madl collected semiaquatic Hemiptera on Nosy Boraha (Île Sainte Marie), a small island near the north-eastern coast of Madagascar. The collected material contains five species of Rhagovelia Mayr, 1865, two of which are new to science. Both Rhagovelia madlisp. nov. and Rhagovelia kalalaoensis
