Constructing Isoscapes of δ13C, δ15N and δ34S Baselines Within a River System: A Spatial Stream Network Modelling Approach

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Stable isotopes of carbon (δ13C), nitrogen (δ15N), and sulphur (δ34S) provide insights into freshwater food webs, but spatial variation in values of organisms at lower trophic levels often complicate interpretations. This is especially true in river ecosystems, in which hierarchical networks, directional flows, and aquatic‐terrestrial linkages

Fatty acid composition of the Caprellidea (Crustacea: Amphipoda) from the Strait of Gibraltar

Scientia Marina, 2004
The total fatty acid composition of nine species of caprellidean amphipods collected from the Strait of Gibraltar was investigated. All caprellids were characterised by high levels of polyunsaturated fatty acids, mainly eicosapentaenoic acid, 20:5(n-3 ...

True Locals: Taxonomic, Phylogenetic and Functional Diversity Level Off at Short Distances in Groundwater Amphipods in the Western Balkans

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Multi‐faceted and multi‐scale biodiversity assessments and disentangling the factors driving the biodiversity patterns are fundamental for effective protection of biodiversity and prediction of future community changes. Despite its importance, groundwater is still a data‐deficient and under‐studied ecosystem.
