Article Synopsis
- Anthropogenic warming is causing significant changes in shrub ecosystems worldwide, with 84% of studied sites showing expansions in shrubline, cover, and recruitment rates.
- The average shrubline is advancing at 1.22 m/year, with faster shifts in subarctic and wetter regions, while annual changes in shrub cover and recruitment were recorded at 0.89% and 2.02%, respectively.
- Climate factors like autumn precipitation and winter temperature influence shrubline shifts, whereas summer temperature and seasonal precipitation impact cover and recruitment, indicating local conditions play a role in these changes.
Widespread dam construction has reduced the hydrological connectivity of catchments of various sizes. Nutrients lost from upper catchments can be intercepted by dams and deposited in reservoir sediments, and this reduces downstream nutrient transportation. Few previous studies have assessed historical nutrient deposition rates (NDRs) in man-made reservoirs.
