General spatial spectral variation in rocky intertidal communities from three biogeographical regions
Abstract Aim Understanding general spatial patterns of multiple species is a central aim of biogeography. Spatial analyses of coastal marine assemblages have shown an emergent pattern in that the variability in population abundances increases with increasing spatial scale of observation; i.e. a “red...

Abstract Aim Understanding general spatial patterns of multiple species is a central aim of biogeography. Spatial analyses of coastal marine assemblages have shown an emergent pattern in that the variability in population abundances increases with increasing spatial scale of observation; i.e. a “red” spectrum of variation in population abundances. However, the generalization of these patterns to other ecological levels and across biogeographical regions remains unexplored. Here, we evaluate the consistency of a reddened relationship between the scale of observation and the variance in ecosystem properties in sessile intertidal rocky‐shore assemblages across three biogeographical regions. Location Replicate sites located in temperate (southern‐central Chile), sub‐Antarctic (Chilean South Patagonia) and Antarctic (West Antarctic Peninsula) regions. Methods A total of 16,225 photo‐quadrants were used to analyse local patterns of total community cover, bare substratum, total algal cover and total invertebrate cover. We used spectral analyses in which the spatial variance of each property was decomposed along a gradient of increasing distances between observations.
