Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

open access: yesRiver Research and Applications, Volume 42, Issue 7, Page 1500-1519, September 2026.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

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

open access: yesOikos, 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 ...

Contulma vascaina sp. n. (Insecta: Trichoptera: Anomalopsychidae), a new species from Rio de Janeiro state, southeastern Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2018
The caddisfly genus Contulma Flint, 1969, with 30 described species, is endemic to the Neotropics. In addition to the five species currently recorded from Brazil, a new species of Contulma is described and illustrated in this work.

Prospects for Complete DNA Barcode Coverage of the New Zealand Insect Fauna

open access: yesJournal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.
The accurate identification of insects supports conservation, biosecurity and ecological monitoring. However, morphological identification is constrained by taxonomic complexity, undescribed diversity, and limited expertise. DNA barcoding can alleviate some of these challenges and complement morphological identification, if reference data are ...

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

open access: yesEcological 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 ...

Do solar farms alter invertebrate communities and reduce activity of the common pipistrelle bat (Pipistrellus pipistrellus) through prey‐mediated effects?

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We investigated the effects of ground‐mounted solar photovoltaic (PV) farms on arthropod communities and tested whether changes in prey availability explain reduced bat activity. Solar farms altered arthropod community composition but did not reduce the abundance of key dipteran prey for Pipistrellus pipistrellus.

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1366-1382, July 2026.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied
