摘要
The influence of water retention time and depth variation on the macrophyte community in two small shallow lakes in the northwest of Spain was studied. One lake is periodically flooded and the other deeper lake, which is usually inundated, dries up sporadically. The influence of water regime and the spatial heterogeneity of the abiotic environment on diversity values and their temporal evolution are shown. For each lake, a model of horizontal arrangement of species is established. A differential arrangement of optima for dominant species was observed along the depth gradient. This arrangement remained constant in time.
