The role of land use in terrestrial support of boreal lake food webs - Nature Communications Recognising cross-ecosystem linkages between terrestrial and aquatic ecosystems is vital for sustainable management and conservation of freshwater biota. Here, the authors show that land use…

🌍/💧 Cross-ecosystem connections matter: #FreshRestore ( #BiodivRestore) shows how land management shapes lake food webs in 35 boreal lakes. Terrestrial organic matter supports aquatic life, with benthic consumers' allochthony dropping from forested to agricultural areas.

Differences in trophic niches and life-history traits between brook trout and brown trout in alpine lake food webs - Hydrobiologia Trophic ecology of lacustrine salmonid populations is well-documented in North America and northern Europe, highlighting their role in aquatic ecosystems. However, there is a notable gap in…

🐟 #FreshRestore ( #BiodivRestore) compares brook and brown trouts in Spanish alpine lakes, identifying traits aiding non-native salmonid establishment, such as flexible feeding, dietary shifts, and early maturation.

🔬 Traditional biomarkers fall short in tracing basal resources. #FreshRestore ( #BiodivRestore) shows how carbon stable isotope analysis (with δ13C-EAA) offers unique fingerprints to track food webs. Standardised protocols & more research needed!
