Small-scale spatial variation in age and size

Webbly and structure, which are expressed by spatial variations along the altitudinal gradient. At the same time, temporal patterns were not inuenced by altitude-related environmen-tal variation, resulting in a similar dynamic behaviour across the gradient, suggesting that broad-scale factors may play a more important role than local ones. Webevaluated smaller-scale variations in benthic charac-teristics within a culture site (1) under long lines vs. between long lines or (2) in areas with juvenile bivalves (i.e. at the beginning of the growth cycle) vs. bivalves of commercial size. Such variation should be taken into account when evaluating the influence of
