Patterns and Current Changes in Alpine Plant DiversityGlobal warming, resulting from increased concentrations of greenhouse gases, may affect ecosystems in different ways and to various extents (Emanuel et al. 1985; Bolin et al. 1986; Solomon and Shugart 1993, etc.). Coral reefs, mangroves, the arctic tundra, and high mountain ecosystems are particularly vulnerable (Markham et al. 1993).作者: 知識(shí)分子 時(shí)間: 2025-3-22 04:24
