Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, Volume 95, Issue 9, Page 1629-1641, September 2026.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

First records of Bessierus doloris Thomas & Orth (Ephemeroptera: Leptophlebiidae) in Brazil

Revista Chilena de Entomología, 2020
We report the first occurrence of Bessierus doloris in Brazil. Additionally, we provide biological and taxonomic information on this species. Male imagos specimens were collected with a Pennsylvania light trap in the Apiaú region, municipality of Mucajaí,

Are Species Distribution Models That Use Climate Variables Suitable to Forecast the Changing Distribution of Freshwater Organisms?

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Species distribution models can be used to identify locations with environmental conditions suitable for populations in the past, present and future. However, climate variables commonly applied in species distribution models may be unsuitable for freshwater species because their explanatory power is difficult to assess.

An unseen synchrony or recurrent resource pulse opportunity? linking fisheries with aeroecology

Remote Sensing in Ecology and Conservation, 2020
Understanding insect and fish interactions from a spatial and temporal perspective can have implications on large‐scale phenology in freshwater systems, yet current information is limited.

A new species of Bungona in Turkey (Ephemeroptera, Baetidae): an unexpected biogeographic pattern within a pantropical complex of mayflies [PDF]

Zoosystematics and Evolution, 2019
By using an integrative approach, we describe a new species of mayfly, Bungona (Chopralla) pontica sp. n., from Turkey. The discovery of a representative of the tropical mayfly genus Bungona in the Middle East is rather unexpected.

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, Volume 2026, Issue 8, August 2026.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

Increasing the Spatial and Temporal Resolution of Snow Water Equivalent Estimates Using SNOTEL Data and Low‐Cost Sensing

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT Accurate estimation of snow water equivalent (SWE) is critical for understanding hydrologic processes in snow‐dominated watersheds. This study presents a method for improving the spatial and temporal resolution of SWE estimates using low‐cost snow depth sensors, manual snow sampling, and snow density data from nearby SNOwpack TELemetry (SNOTEL)

Limited effects of chronic exposure to field-realistic concentrations of carbamazepine on Deleatidium spp. mayfly nymphs

Ecotoxicology and Environmental Safety
Pharmaceuticals are a class of emerging organic contaminants found in freshwaters. Potential chronic effects of many legacy drugs (those developed pre-2006) on freshwater biota were not investigated thoroughly before their market release.

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

Ecological Entomology, Volume 51, Issue 4, Page 672-689, August 2026.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...
