Habitat Preferences and Distribution of Ephemera orientalis (Ephemeroptera: Ephemeridae) in the Hangang River, South Korea

open access: yesEntomological Research, Volume 56, Issue 10, October 2026.
ABSTRACT This study characterized the spatial distribution patterns and habitat preference of Ephemera orientalis larvae in the Hangang River based on four surveys conducted in April, June, August, and October 2024. Field surveys were conducted at 10 sites along a 24 km reach, with five cross‐sectional sampling points per site.

Pesticide‐Free Rice Paddies Promote Diverse and Distinct Aquatic Invertebrate Communities in Cool‐Temperate Agroecosystems

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Freshwater wetlands are disappearing across agricultural landscapes, prompting interest in pesticide‐free rice paddies as multifunctional habitats. Across 2 years, rice paddies supported higher local macroinvertebrate density and richness than nearby natural wetlands, although wetlands maintained greater regional diversity and more heterogeneous ...

Are Intermittent Rivers in the Karst Mediterranean Region of the Balkans Suitable as Mayfly Habitats?

open access: yesDiversity, 2023
Intermittent rivers, common in dry parts of the world, such as the Mediterranean region, are hydrologically harsh habitats characterized by periodical flow cessation.

Reproduction on the Rocks: Life History of a Freshwater Macrobioeroding Bivalve

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
ABSTRACT Macrobioerosion, the excavation and removal of consolidated mineral substrates by macrofauna, is well established in marine systems, where macrobioeroders drive carbonate cycling, sediment production and habitat formation. In freshwater ecosystems, however, it has been documented in only a small number of invertebrate taxa and remains a poorly

Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

open access: yesRiver Research and Applications, Volume 42, Issue 7, Page 1442-1458, September 2026.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, Volume 42, Issue 7, Page 1474-1499, September 2026.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Phylogenetic Biogeography of Mayflies

open access: yesAnnals of the Missouri Botanical Garden, 1975
The number of biogeographers who confidently drew dispersal routes on fixed continent maps ten or more years ago and now just as confidently draw dispersals of the same organisms on continental drift maps must cause us to seriously question the procedures of biogeographers.

Do omnivorous shrimp influence mayfly nymph life history traits in a tropical island stream?

open access: yesRevista de Biología Tropical, 2014
Interspecific interactions can play an important role in determining habitat selection and resource use between competing species. We examined interactions between an omnivorous shrimp and a grazing mayfly, two co-dominant taxa found in Puerto Rican ...

Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

Eurylophella karelica Tiensuu, 1935 (Insecta: Ephemeroptera: Ephemerellidae) – an additional species to the mayfly fauna of Ukraine and notes on distribution of the family in the country

open access: yesJournal of Threatened Taxa, 2020
A rare European species, Eurylophella karelica Tiensuu, 1935 (Ephemeroptera: Ephemerellidae) is reported for the first time from Ukraine.  The larvae of the species were found within Ukrainian Polissya region in the Pripyat’ River basin.
