Spatiotemporal eDNA Monitoring of Marine Biodiversity in a Hyperurbanised Coastal Environment

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Using environmental DNA and a metabarcoding approach, we amplified and sequenced the cytochrome oxidase subunit I (COI) gene for invertebrates and the 16S rRNA gene for vertebrates. Our spatiotemporal analyses over a year and across four sites in Singapore revealed distinct communities between sites and timepoints for both the COI and 16S rRNA assays ...

Acanthodasys caribbeanensis sp. n., a new species of Thaumastodermatidae (Gastrotricha, Macrodasyida) from Belize and Panama

ZooKeys, 2010
We describe one new species of Acanthodasys (Gastrotricha, Macrodasyida, Thaumastodermatidae) collected from sublittoral sites around Carrie Bow Cay, Belize and Isla Colón in the Bocas del Toro archipelago, Panama.

Karst spring microbial diversity differs across an oxygen-sulphide ecocline and reveals potential for novel taxa discovery

Acta Carsologica, 2019
Strong geochemical gradients of dissolved oxygen and sulphide establish habitats where specialized bacterial and archaeal taxonomic groups occupy specific redox-sensitive niches, primarily based on metabolic and ecological requirements.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling

Molecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Spatial and Seasonal Biodiversity Variation in a Large Mediterranean Lagoon Using Environmental DNA Metabarcoding Through Sponge Tissue Collection

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Ecosystem monitoring is essential for preventing biodiversity loss, and in the Mar Menor lagoon (SE Spain), where intensive agriculture has led to eutrophication and mass mortality of marine fauna, it is critical for assessing the status of flora and fauna and informing conservation actions.

Evaluation of sampling methods for periphytic fauna in macrophytes at the Espinhaço Mountain Range Biosphere Reserve, Minas Gerais State, Brazil = Avaliação dos métodos de amostragem para fauna perifítica em macrófitas na Reserva da Biosfera, Serra do Espinhaço, Estado de Minas Gerais, Brasil

Acta Scientiarum: Biological Sciences, 2008
The methods “Jar”, “Manual Removal” and “modified Ekman Dredge” wereevaluated for sampling periphyton fauna associated with aquatic macrophytes. Sixty-three samples were collected from five lentic and three lotic water bodies at the Espinhaço Mountain ...

Environmental DNA Documents Ecosystem‐Wide Biodiversity Within the Marine Protected Area Stellwagen Bank National Marine Sanctuary

Environmental DNA, Volume 7, Issue 3, May–June 2025.
Three marker genes targeting prokaryotic, eukaryotic, and vertebrate diversity were used to assess biodiversity within Stellwagen Bank National Marine Sanctuary. High levels of biodiversity were seen across the sampled area, with distinct communities across surface water, bottom water, and sediment.

Gastrotricha – not only in sediments: new epiphytic species of Chaetonotida from the Jubilee Greenhouse of the Botanical Garden in Kraków

European Journal of Taxonomy, 2019
Although Gastrotricha have previously been recorded in bottom sediments of greenhouses as well as in micro-reservoirs of Bromeliaceae, palm houses provide a more specific microhabitat for these animals that often originate from different regions of the ...
