A global estimator of C and N isotope baselines for fresh waters

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 992-1006, March 2026.
Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

A cost-effective method to quantify biological surface sediment reworking [PDF]

, 2013
We propose a simple and inexpensive method to determine the rate and pattern of surface sediment reworking by benthic organisms. Unlike many existing methods commonly used in bioturbation studies, which usually require sediment sampling, our approach is ...

High interspecific variation in nutrient excretion within a guild of closely related caddisfly species

, 2018
Understanding the amount of variation in functional traits between closely related species within guilds is critical for understanding links between community composition and ecosystem processes.

Assessing the phylogeographic history of the montane caddisfly Thremma gallicum using mitochondrial and restriction-site-associated DNA (RAD) markers

Ecology and Evolution, 2015
Repeated Quaternary glaciations have significantly shaped the present distribution and diversity of several European species in aquatic and terrestrial habitats. To study the phylogeography of freshwater invertebrates, patterns of intraspecific variation

Occupied and abandoned structures from ecosystem engineering differentially facilitate stream community colonization

Ecosphere, 2019
Ecosystem engineers transform habitats in ways that facilitate a diversity of species; however, few investigations have isolated short‐term effects of engineers from the longer‐term legacy effects of their engineered structures.

Hydroptila angustata Mosely, 1939 (Trichoptera: Hydroptilidae): A significant addition to the Micro-Caddisfly fauna of Northwest Africa [PDF]

Journal of Insect Biodiversity and Systematics
The micro-caddisfly fauna of Morocco is still poorly known, despite its geographical location and the exceptional diversity of its ecosystems. Recent field surveys in northern Morocco have resulted in the discovery of Hydroptila angustata Mosely, 1939 ...
