Ecological pathways connecting riverine drought to community change across space and time

open access: yesEcological Monographs, Volume 95, Issue 3, August 2025.
Abstract Climate change is intensifying droughts via reduced snowpack and accelerated snowmelt in high mountains globally, altering community structure in snow‐dependent rivers. To predict impending ecological change in rivers, we must understand the importance of the abiotic and biotic mechanisms connecting hydrologic change to biodiversity change and

Different processes and constraints drive the assembly of deep‐sea hydrothermal vent and sunken wood communities

open access: yesEcosphere, Volume 16, Issue 8, August 2025.
Abstract Niche processes mainly dictate the successful establishment and coexistence of species along gradients of community drivers such as energy availability and environmental stress. Deep‐sea chemosynthetic habitats such as hydrothermal vents and wood falls show concomitant gradients of energy availability and stress because productivity is fueled ...

Aquatic habitat response to small dam removal demonstrates recovery in three years

open access: yesEcosphere, Volume 16, Issue 6, June 2025.
Abstract Dams disrupt river networks by interrupting longitudinal transport of sediment and nutrients and obstructing the movement of aquatic organisms. Increasingly, water resource managers are looking for dam removal as a solution to restore connectivity and improve aquatic habitats, water quality, and fish passage.

Capture—Incubate—Release: An Animal‐Friendly Approach to Assess Local Aquatic Macroinvertebrate Species Diversity Through Environmental DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
We assessed whether we can combine the advantages of both bulk and eDNA metabarcoding, that is, obtaining a local signal and being minimally invasive, to improve local invertebrate detections in streams using water samples. We quantified eDNA release over time after a short incubation in water for single species using qPCR and for bulk samples using ...

Seasonal Evaluation of Ephemeroptera (Insecta) Fauna of Eastern Mediterranean Basin and Determination of Water Quality With Physicochemical Parameters and Benthic Metrics

open access: yesEcohydrology, Volume 18, Issue 3, April‐May 2025.
ABSTRACT This study evaluates the Ephemeroptera fauna and water quality in the Eastern Mediterranean Basin using physicochemical variables and benthic metrics, offering an ecological water quality analysis. Fieldwork conducted during the spring, summer and autumn of 2019 across 20 localities revealed 965 individuals belonging to 17 species from seven ...
