Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains

open access: yesOikos, Volume 2026, Issue 5, May 2026.
Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.

Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

open access: yesJournal of Polymer Science, Volume 64, Issue 9, Page 1860-1894, 1 May 2026.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

Benthic Macroinvertebrate Recovery After Wastewater Treatment Plant Upgrades: Implications for Biomonitoring

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 824-836, May 2026.
ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and

The Effects of Supplementation of Chlorella vulgaris Biomass on Egg Production and Composition of Laying Hens

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Dietary supplementation with Chlorella vulgaris up to 0.5% improved laying hen productivity, increasing egg number and daily production rate without compromising egg weight. Egg nutritional composition remained largely unchanged, with only indicative trends in fatty acid ratio and cholesterol, suggesting potential for productivity enhancement without ...
