1·There exists certain degree of similarities between industrial clusters and species population.
产业集群与生物种群具有一定的相似性。
2·The future of slender-billed vultures in India may lie with the first of their kind to breed in captivity following a 97% crash in the species population since the 1990s - or it may not.
印度尖嘴秃鹰的未来也许取决于首次尝试的人工繁殖，自从1990年以来，它的数量已经减少了97%。
3·Remarkably, despite significant differences in habitat and behavior, many species of lepidoptera have population cycles of similar length, between eight and eleven years.
值得注意的是，尽管鳞翅目昆虫在栖息地和行为上存在显著差异，但许多种类的鳞翅目昆虫的种群周期相似，在8到11年之间。
4·It's not only the study of human population, but the populations of non-human species, including viruses.
这不仅是对人类种群的研究，也是对非人类种群（包括病毒）的研究。
5·Some groups that had descended from the same parent population were no longer reproductively compatible—they had evolved into separate species.
一些由同一亲本群体进化而来的群体在繁殖上不再相容——他们进化成了不同的物种。
6·If the population of these other species were increased, the number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease would likely decline.
如果这些其他物种的种群数量增加，蜱类捕获细菌的数量就会减少，因此感染莱姆病的人数就会减少。
7·Even if the new population is of a different species, it can approximately fill the niche vacated by the extinct population and keep the food web intact.
即使新的种群属于不同物种，它也可以大致填补已灭绝种群空出的生态位，保持食物网的完整。
8·Because each individual is short-lived, the population of an opportunist species is likely to be adversely affected by drought, bad winters, or floods.
因为每个个体的生命都是短暂的，“机会主义者”这类物种的群体数量很可能受到干旱、严冬或者洪水等不利因素的影响。
9·Within that same time frame, we evolved into an urban species, in which 60% of the human population now lives vertically in cities.
在同一时期，人类逐渐开始适应城市生活，目前有60%的人口分布在城市的纵深之中。
10·Population data for most of the world's 35 seahorse species is sparse.
世界上35种海马中大多数的种群数据都非常稀少。
