eDNA metabarcoding biodiversity of freshwater fish in the Alpine area

, 2021
Environmental DNA (eDNA) based methods are proving to be a promising tool for freshwater fish biodiversity assessment in Europe within the Water Framework Directive (WFD, 2000/60/EC) especially for large rivers and lakes where current fish monitoring techniques have known shortcomings.

Fine‐Scale Oceanographic Processes Shape Marine Biodiversity Patterns Inferred From Environmental DNA in the Galápagos Islands

Diversity and Distributions, Volume 32, Issue 8, August 2026.
ABSTRACT Aim Uncovering the drivers that shape biodiversity patterns is critical to understanding ecological and evolutionary dynamics. Despite evidence that biodiversity is influenced by processes at different spatial scales, little is known about the role of fine‐scale oceanographic processes on the structure of marine communities.

The Biodiversity of Retreating Glaciers Leaves an Ecological Legacy in Emerging Soil Communities

Global Change Biology, Volume 32, Issue 8, August 2026.
We provide the first multi‐taxa assessment of biodiversity transitions across the supraglacial‐proglacial interface, using eDNA metabarcoding across five glacier systems. Recently deglaciated soils resemble supraglacial communities taxonomically and functionally, markedly for microbes and weakly for animals, with microbial similarity declining rapidly ...

Terrestrial Arthropod Responses to Arctic Cryosphere Degradation

Global Change Biology, Volume 32, Issue 8, August 2026.
Changes in Arctic snow and ice are impacting terrestrial arthropods—for example, thinner snowpacks alter phenological synchrony and soil fauna survival; thawing permafrost increases decomposition, and glacial ice loss leads to the disappearance of adapted specialists; sea ice decline will have many indirect impacts for arthropods.

Plant Phylogenetic History, Not Diversity, Drives Insect Biodiversity Across South Africa's Biomes

Global Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Insects provide essential ecosystem services, but there is a concern that insect abundance is in rapid decline. Identifying trends in insect biodiversity is challenging because we lack baseline data for most biogeographic regions, and most insect species remain undescribed.

Substrate‐driven enrichment and eDNA metabarcoding reveal indigenous microbiomes in mangrove sediments with potential for ammonia and nitrite transformation

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Effective management of ammonia and nitrite remains a major challenge in intensive shrimp aquaculture, where excessive nitrogen loading compromises water quality and animal health. Indigenous microbial communities inhabiting mangrove sediments are widely considered potential sources of ammonia‐ and nitrite‐transforming microorganisms; however,

Sedimentary DNA and Fossil Archives Reveal Long‐Term Phytoplankton Shifts and Their Biogeochemical Influence in a Subtropical Lake

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Understanding long‐term phytoplankton community dynamics is essential for assessing ecological resilience and informing lake management under global change. However, centennial‐scale patterns of phytoplankton dynamics remain poorly resolved due to the limited taxonomic resolution of traditional fossil‐based paleoecological approaches.

Fish eDNA Composition Along a Gradient of Freshwater eDNA in an Estuarine Bay

Environmental DNA
Metabarcoding of environmental DNA (eDNA) is becoming practically applied to fish monitoring and conservation surveys in estuaries. However, estuarine bays may be an unsuitable zone to use eDNA metabarcoding because they are affected by eDNA originating ...

Comparing qPCR and eDNA-metabarcoding for detection of elusive lampreys

, 2023
In this study I compared the detection sensitivity of qPCR and DNA-metabarcoding for lamprey in 45 locations, with two samples collected from each location. I compared if the samples were positive or negative for lamprey DNA within each method, and then compared the result from both methods to investigate presence and absence of lamprey for each ...
