Metagenomics Reveals Microbial Community Shifts Associated With Contrasting Anthropogenic Impacts in Freshwater Sources of A Coastal Protected Area in Southeastern Brazil

open access: yesWater Environment Research, Volume 98, Issue 9, September 2026.
Metagenomics revealed distinct anthropogenic signatures in the microbiome of freshwater sources on Marambaia Island, supported by the Anthropogenic Impact Index (AII). Impacted sites showed lower microbial diversity, enrichment of fecal‐associated taxa, and 14 antimicrobial resistance genes, whereas conductivity, salinity, and turbidity explained 88.1%

Forest Floor Protection: The Critical Defense Against Post‐Harvest Soil Carbon Loss

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Understanding the dynamics of soil carbon accumulation and loss following forest harvest is crucial for sustainable forest operations in western Canada. However, the region's diverse climates and forest types complicate broad generalizations regarding disturbance impacts. We synthesized 20 years of soil carbon stock (SCS) data from the British

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds

Atmospheric Microbial Transport to Antarctica and Its Ecological Implications: A Systematic Review

open access: yesEnvironmental Microbiology, Volume 28, Issue 9, September 2026.
Atmospheric transport to Antarctica operates via long‐range advection, marine aerosolization, and local resuspension, acting as a strict ecological filter. This selective barrier could actively shape local ecosystems by seeding them with functionally distinct, stress‐adapted microbial pioneers capable of surviving extreme conditions.

Occurrence of Food Chemical Contaminants in Entomophagy: Implications for Food Safety and Future Risk Assessment—A Scoping Review

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Entomophagy is increasingly recognized as a sustainable alternative to conventional protein sources due to its low environmental impact. However, ensuring its safety requires careful evaluation of chemical contaminants of food safety concern.

From Heritage to Innovation: A Review of the Safety and Production of Aminopeptide Seasonings

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Aminopeptide seasonings, produced through proteolytic fermentation or enzymatic hydrolysis, represent a global family of ingredients with a high concentration of umami‐active free amino acids and umami‐ or kokumi‐active peptides derived from protein‐rich substrates.

Aquatic Insect Thermal Responses Vary by Physiological Rate and Diet

open access: yesFreshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Temperature is an important control on metabolic rate and organismal contribution to ecosystem processes. Many studies have measured aquatic insect thermal performance, but fewer have simultaneously measured thermal responses for multiple physiological rates and examined how these responses are modulated by diet.

Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia

open access: yesGeobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

Non‐Fungi Diversity Present in Soil and Snow Impacted by Anthropogenic Activity in King George Island, Maritime Antarctica Using Metabarcoding Approach

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT The Antarctic Peninsula shows a fast‐rising temperature trend, increasing the risk of colonization by non‐native species, such as the invasive Poa annua. The “cryptic diversity” of largely unknown microscopic propagules in soil and snow poses a significant threat, as traditional morphological surveys are inadequate.
