Rethinking the ecological significance of network topology in the area of environmental DNA (eDNA) data represents a major challenge in ecology, as network structure fundamentally influences ecosystem functioning. However, translating network analysis into tools for ecological assessment is still in its infancy. Here, we present an innovative approach integrating eDNA inventories with graph theory (specifically graphlet analys...

The AquaEcOmics meeting brought together 280 scientists applying omics tools to aquatic research in March 2025 (Evian‐les‐Bains, France). We synthesised here the main outcomes from the 167 presentations which were given. A similar number of presentations were about micro‐ and macroorganisms. While studies on macroorganisms mostly focused on stakeholder‐driven research and methodology development, studies on microorganisms tend...

Despite small freshwater ecosystems being biodiversity reservoirs and contributing significantly to greenhouse fluxes, their microbial communities remain largely understudied. Yet, microorganisms intervene in biogeochemical cycling and impact water quality. Because of their small size, these ecosystems are in principle more sensitive to disturbances, seasonal variation and pluri‐annual climate change. However, how microbial co...

While considerable insights on the ecological consequences of climate change have been gained from studies conducted on remote lakes, little has been done on lakes under direct human exposure. Ecosystem vulnerability and responses to climate warming might yet largely depend on the ecological state and thus on local anthropogenic pressures. We tested this hypothesis through a paleolimnological approach on three temperate large...
