Aim To investigate the importance of autumn phenology in controlling interannual variability of forest net ecosystem productivity ( NEP ) and to derive new phenological metrics to explain the interannual variability of NEP . Location N orth A merica and E urope. Method Flux data from nine deciduous broadleaf forests ( DBF ) and 13 evergreen needleleaf forests ( ENF ) across N orth A merica and E urope (212 site‐years) were use...

Calcium is an important element in water bodies that plays a pivotal role in numerous biological processes; however, its effects on bloom‐forming cyanobacteria have been studied only rarely. In the present study, the effects of calcium on Microcystis aeruginosa , a major bloom‐forming cyanobacterium, were investigated. Significant decreases in growth, chlorophyll a and maximum electron transport rate were shown when calcium wa...
