Plant diversity and community composition in managed humid coastal dune slacks in NW England.

Humid coastal dune slacks are an endangered habitat in Northwestern Europe. In the UK, dune slacks are currently classified as being in 'unfavourable' condition, with projected decrease in England of up to 30% by 2036. Studies in mainland Europe suggest that regional factors (e.

Plant responses to decadal scale increments in atmospheric CO concentration: comparing two stomatal conductance sampling methods.

Our study demonstrated that the species respond non-linearly to increases in CO concentration when exposed to decadal changes in CO, representing the year 1987, 2025, 2051, and 2070, respectively. There are several lines of evidence suggesting that the vast majority of C3 plants respond to elevated atmospheric CO by decreasing their stomatal conductance (g). However, in the majority of CO enrichment studies, the response to elevated CO are tested between plants grown under ambient (380-420 ppm) and high (538-680 ppm) CO concentrations and measured usually at single time points in a diurnal cycle.
