物种多样性

But the red squirrel example ket coming up: an environment with very low "measurable" spread of biological diversity, but one which might be better from the point of view of species survival.

但有一个名叫ket的红松鼠的例子指出：一种难于衡量生物多样性传播的环境，从物种生存的角度来说更好。

The results showed that the influence of negative interactions among woody species in this subtropical plot was greater than other studied tropical plots. All the 52 examined woody species at the Fushan plot behaved as diversity repeller within a 50 m scale and did not show scale-dependent neutral behavior.

结果显示，种间竞争作用在亚热带的福山森林样区内的影响力比在热带样区更为显著，在50 m空间尺度下，所有检验的52种福山林木物种是多样性排斥者，并且其中性性质并不会因空间尺度不同而变化。

Finally, regression analysis shows that, isolation by distance exists in rhesus macaques.

我们的初步结果提示，遗传多样性低与物种的濒危没有完全的对应关系。

As an illustration of artificial selection, he describes fancy pigeon breeding, noting that "the diversity of the breeds is something astonishing", yet all were descended from one species of rock pigeon.

作为说明人工选择的例子，他描述了观赏鸽的育种，指出"品种多样性是惊人的"，但它们都是从野鸽一个物种传下来的。

In the beginning of foundation of S. alterniflora salt marsh, the abundance and diversity of macrobenthos were at a lower level, especial for the crabs.

互花米草盐沼发育初期，其大型底栖动物群落的物种丰度和多样性较低，特别是活动能力强的蟹类较少。

In this study, the researches are focused on slighting topics, such as the bird biodiversity and heterogeneity of bird community, improvement of statistic methods and blending landscape ecology with avian ecology on scale and heterogeneity.

l、突破现行鸟类群落研究思路，本文结合与鸟类分布密切相关的生境因子，将鸟类分为不同的类型后再进行生态学分析，以避免冗余种对多样性和聚类的影响，正确显示物种在生态系统中的不同地位和作用。

Result The results showed that the invasion of Solidago canadensi had a large effects on species, composing and vegetable diversity of plant community on island.

结果］结果表明，外来植物加拿大一枝黄花的入侵已经对海岛植物群落的种类及其构成、物种丰富度和植物多样性带来了较大程度的影响。

Solidago canadensi invaded more severely, the species was lower, the vegetable diversity of the plant community was smaller.

加拿大一枝黄花入侵的程度越严重，群落中物种丰富度越低，植物多样性越小。
