5/6 Species richness, functional, and genetic sequence diversity exhibited stronger negative responses to human activities in larger catchments. In contrast, phylogenetic diversity showed the strongest negative effects in smaller catchments.

2/6 ➡️ 1st #paper evaluated robustness of eDNA-derived biodiversity patterns, using original results & re-analysis w/ common bioinformatic workflow.
Species richness estimates were overall consistent with original analyses, despite high variability in bioinformatic approaches in original studies.

What a joy to find 4 🐛🐛🐛🐛 of the spurge hawk-moth in our garden! We just have a few m2, yet keep it diverse, with native plants and extensive maintenance (and no pesticides nor short cut lawn). Starts to pay off😊 #BiodiversityRocks

3/4 We estimated a spatial range of #LULC effects extending up to about 20 km upstream ↗️ from sampling sites, and explained nearly 60% of the variance in the observed species richness, associated with cropland🌾, forest🌳, and urban 🏙️ area LULC categories.
