Enabling Quantitative eDNA Monitoring in Lotic Ecosystems by Incorporating Hydrological Characteristics and Allometric Scaling

Charlotte Van Driessche, Teun Everts, Quentin Mauvisseau, Sabrina Neyrinck et autres

ABSTRACT Effective freshwater biodiversity monitoring requires scalable methods to estimate fish abundance or biomass. Environmental DNA (eDNA)‐based approaches offer a promising alternative to observational methods. However, translating eDNA concentrations into reliable biomass estimates remains difficult in flowing waters because hydrological dilution and …

Integrating eDNA metabarcoding into fish-based ecological indices for lowland rivers under the EU Water Framework Directive

Charlotte Van Driessche, Teun Everts, Sabrina Neyrinck, Gerlinde Van Thuyne et autres

Abstract Environmental DNA (eDNA) metabarcoding is widely used as a non-invasive alternative to catch-based methods for fish monitoring in general, with strong potential to support the EU Water Framework Directive (WFD) in particular. However, its suitability for ecological index calculation and intercalibration …

Wastewater treatment effectively eliminates exogenous eDNA, preventing downstream false-positive detections

Charlotte Van Driessche, Teun Everts, Berdien De Beer, Sabrina Neyrinck et autres

Environmental DNA (eDNA) is widely applied to monitor aquatic biodiversity, but false-positive detections may arise when DNA from consumed or processed organisms is discharged to waterways through domestic wastewater. We experimentally tested whether such wastewater-derived eDNA persists through municipal treatment and contributes …

First record of Atlantic menhaden, Brevoortia tyrannus (Latrobe, 1802) in the Scheldt Estuary (northwestern Europe)

Jelger Erik Herder, RICK MIDDELBOS, David Halfmaerten, Rein Brys

The natural range of a species is shaped by a complex interplay of biotic and abiotic factors, including climate, habitat availability, food resources, interactions with other species, geographical barriers, and genetic factors (Sexton et al. 2009).The Atlantic menhaden (Brevoortia tyrannus (Latrobe, 1802)) …

Quicklime-based eradication attempt of Xenopus laevis as a model for controlling pond invasions

Teun Everts, Loïc van Doorn, Tim Adriaens, Jeroen Speybroeck et autres

Aquatic non-native invasive species are notoriously difficult to eradicate, particularly in pondscapes where populations can spread rapidly, persist in unmanaged refugia, and recolonise treated sites.In such contexts, high-intensity management interventions may be justified, balancing short-term collateral impacts against the prevention of permanent …

Limited role of aquatic habitat complexity in mitigating the ecological impact of invasive bullfrogs on native amphibians

Jonathan Tibo, Rein Brys, Hans Jacquemyn, Charlotte Van Driessche et autres

Spatial overlap in habitat use and structural habitat complexity can shape the ecological impact of biological invasions. Environmental conditions that mitigate these impacts can be exploited in nature-based conservation strategies aimed at damage reduction when complete eradication is no longer feasible. In …

Mapping the northernmost transnational non-native population of Xenopus laevis using pooled eDNA sampling

Teun Everts, Loïc van Doorn, Tim Adriaens, Sabrina Neyrinck et autres

Early-detection-rapid response (EDRR) programs are invaluable for managing incipient invasions, but require monitoring strategies that maximize search coverage and minimize costs. While environmental DNA (eDNA)-based monitoring techniques are now widely used for monitoring aquatic invasions, the large monitoring efforts in EDRR programs …

Interactions outside local patches contribute to the compound topology of plant–pollinator networks in fragmented dune slacks

Arne Devriese, Gerrit Peeters, Rein Brys, Hans Jacquemyn

Plants and pollinators engage in ephemeral interactions that are essential for both plant reproduction and pollinator fitness. Most plant species interact with multiple pollinator species and, similarly, most pollinators visit multiple plant species, leading to complex networks of interactions. A better understanding …
