the mountain coniferous forests. In fact, these variables generally are the most important factors affecting species distribution and vegetation zonation along environmental gradients. Nevertheless, understanding the ecology of these forest ecosystems will not be complete without investigation of thLUMEN 发表于 2025-3-26 02:58:18

There was, however, no consistent trend with altitude. On the other hand, nrorphometry and allometric relat神秘 发表于 2025-3-26 06:16:38
Stefan Lüddemannmponents output equals inputs to within 10%, i.e. these compounds simply pass through the lake. For H., and possibly NH. and N0., inputs exceed outputs. Because gaseous phases are not measured the N budgets are uncertain. A mechanism that leads to ’retention’ of both H. and S0. is sulfate reductionPanacea 发表于 2025-3-26 11:00:28
