Rethinking intensification: Biodiversity‐inclusive management sustains coconut yields

PLANTS, PEOPLE, PLANET, EarlyView.
Coconut palm expansion in West Africa will shape rural livelihoods and ecosystems. Our findings show that intensive practices reduce beneficial soil fungi and increase pathogens, threatening long‐term productivity. Lower‐intensity management that retains ground vegetation can sustain or boost yields while improving soil health.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Metabarcoding by Combining Environmental DNA with Environmental RNA to Monitor Fish Species in the Han River, Korea

Fishes, 2023
Fishes are ecologically important organisms that have long lifespans, high mobilities, and diverse trophic levels. Due to their importance, fishes are used as bioindicators for monitoring aquatic environments. One method for monitoring fishes is based on

Link prediction in ecological meta‐networks under extreme taxonomic bias

Methods in Ecology and Evolution, EarlyView.
Abstract Ecological networks offer powerful insights into community function but, without first characterizing these networks accurately, our ability to detect and interpret changes under environmental stress is limited. We develop an extension of the Covariate‐Informed Link Prediction (COIL) framework to reduce bias in ecological link prediction when ...

Andean fish inventories using an eDNA metabarcoding approach

Discover Conservation
Abstract Fish diversity inventories often rely on capture-based methods, which are typically lethal and may have long-term impacts on fish populations. A promising alternative is environmental DNA (eDNA) metabarcoding —a non-invasive technique that uses molecular DNA barcodes to identify fish species.

Biomonitoring of marine vertebrates in Monterey Bay using eDNA metabarcoding

PLOS ONE, 2017
Molecular analysis of environmental DNA (eDNA) can be used to assess vertebrate biodiversity in aquatic systems, but limited work has applied eDNA technologies to marine waters. Further, there is limited understanding of the spatial distribution of vertebrate eDNA in marine waters.

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Complementary role of environmental DNA for line-transect bird surveys: A field test in a Japanese rice landscape

Ecological Indicators
Monitoring and conserving bird biodiversity in rice landscapes is a global challenge. Although environmental DNA (eDNA) metabarcoding can potentially provide a sensitive and comprehensive assessment of bird biodiversity in farmlands, there is a lack of ...

Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

Methods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...
