Reddened seascapes: experimentally induced shifts in 1/f spectra of spatial variability in rocky intertidal assemblages.

abstract：:The expansion of shrubs and trees across high-latitude ecosystems is one of the most dramatic ecological manifestations of climate change. Most of the work quantifying these changes has been done in small areas and over relatively recent time scales. These land-cover transitions are highly spatially variable, and we h...
