1) species dispersal
物种扩散
1.
Landscape connectivity,as a dominant factor affecting species dispersal,reflects the degree to which the landscape facilitates or impedes organisms\' movement among resources patches.
作为物种扩散的重要影响因子,景观连接度反映了景观促进或阻碍生物体在资源斑块间运动的程度,它也是区域土地可持续利用和生物保护领域的主要指标。
2) seed dispersal
种子扩散
1.
Effect of rodents on seed dispersal and survival of wild apricot (Prunus armeniaca);

补充资料:濒危物种
处于危亡状态的物种。如大熊猫、白鳍豚、朱fe64、银杉、珙桐等。数量稀少,地理分布狭窄。其绝灭趋势除与自然灾害有关外,主要是受人类活动的影响,如不合理的土地利用、森林破坏、水体污染等。其种类仍在不断增加。
