Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

open access: yesSedimentology, Volume 73, Issue 4, Page 1001-1029, June 2026.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...

Three new freshwater species of the genus Achnanthidium (Bacillariophyta, Achnanthidiaceae) from Taiping Lake, China

open access: yesFottea, 2019
We describe three new Achnanthidium species, A. lacustre sp. nov., A. sublanceolatum sp. nov., and A. taipingensis sp. nov., from Taiping Lake, Anhui Province (China) based on light and scanning electron microscopy. A. lacustre sp. nov. belongs to the "A.

From Nest Box to Neighborhood: Patterns of Island Biodiversity Characterized Through eDNA From Little Blue Penguin (Eudyptula minor) Nest Boxes

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
There are many environmental DNA (eDNA) sources within and around a seabird nest. These DNA traces from soil, plant material, feathers, feces, and other nest components enable detection of a wide range of taxa, including plants, fungi, insects, arachnids, mollusks, reptiles, and other vertebrates. Here, we used DNA from nest box feces to obtain signals

Metabarcoding of Sediment eDNA Uncovers Ecological Gradients and Biodiversity in Philippine Mangroves

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Community diversity metrics revealed a clear ecological gradient, with the highest diversity observed in recolonized mature stands, intermediate in the natural stands, and lowest in the restored stands. Taxonomic profiles varied with mangrove stand, age, and zonation.

Seasonal differences and potential biological drivers of the methane paradox in two peri‐Alpine lakes

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Seasonal variations and the biological drivers underlying the methane paradox in freshwater lakes are poorly understood. Here, we investigated the relationship between subsurface methane inventories and phytoplankton in two peri‐Alpine lakes across different seasons.
