Heterogeneity of periphyton in French Mediterranean riversta. We also sampled simultaneously measurements of water quality and other relevant environmental variables. All investigations in mediterranean area show the high sensibility of periphyton reacting quickly to environmental parameters; it is shown by a heterogeneous pattern of colonization at different levels.加剧 发表于 2025-3-30 22:32:42
