| 1. | The trade is large enough to threaten wild populations , causing declines in number and in size of seahorses
由于贸易量相当大，足以威胁野生种群，导致海马数目及体积日渐下降。 |
| 2. | The hetreozygosity and proportion of polymorphic loci of hatchery stock were lower than that of the natural population , which could be related to the small size of the cultured stock and the higher possibility of inbreeding
养殖群体的多态位点比例和杂合度都低于野生种群，这与人工累代养殖过程中，群体较小，近交机会增加有关。 |
| 3. | The vegetative status and the flowering and fruiting developmental rhythm of changnienia amoena were investigated in tiantangzhai population of anhui province during the flowering and fruiting period
摘要对安徽省天堂寨自然保护区独花兰野生种群的花果期节律和营养体状态研究表明，开花植株占观察样本的37 . 5 % ，个体是否开花与假鳞茎数目、地下茎总体积和叶面积呈极显著相关关系。 |
| 4. | Currently hawksbill turtle is listed as critically endangered on iucn red list and appendix i of cites . international trading of hawksbill turtle is prohibited and the wild population is facing a very high risk of extinction
目前玳瑁属世界自然保护联盟濒危物种红色名录中的极度濒危物种类别，以及被列入华盛顿公约附录一中，即禁止一切国际贸易活动，而其野生种群正面临极其严峻的绝种危机。 |
| 5. | It can be difficult for the general public to know what impacts eating different marine species will have on wild populations , and we will respond to the demand for a seafood guide to aid the general public in avoiding species that are in decline due to overexploitation
由于普罗大众一般难以理解进食不同海产对野生种群的影响，因此本会将编制海鲜食品指引，协助指导市民避免进食受过度捕捞影响种群数目正在下降的品种。 |
| 6. | The higher values of heterozygosity and proportions of polymorphic loci of the natural population indicated that the natural resource of c . farreri in china was in good condition with higher genetic diversity . it is urgent to establish the effective measures to protect the resource
栉孔扇贝野生种群的多态位点比例和杂合度处于较高水平，说明我国栉孔扇贝野生种群的遗传多样性水平较高，种质资源尚处于较好状态，应制定相应的渔业生产和管理措施加以保护。 |
| 7. | Rapd ( random amplified polymorphic dna ) technique was used to study the genetic structure and genetic differentiation of the natural population and the hatchery stock of chlamys farreri . amplifications with 20 10 - base primers under predetermined optimal reaction yielded 153 reproducible amplified fragments ranging from 200 to 3000bp . the mean proportions of polymorphic amplified fragments of natural population and the hatchery stock were 73 . 2 % and 70 . 6 % respectively , and the mean hetreozygosities of them were 0 . 27 and 0 . 26 respectively
在对20个野生栉孔扇贝和20个养殖栉孔扇贝的基因组dna的检测中， 20个随机引物共扩增出153条清晰可分辨的dna片段，片段大小在200 3000bp之间，其中野生种群和养殖群体多态性片段分别为112和108条，多态位点比例分别为73 . 2 %和70 . 6 % ，杂合度分别为0 . 27和0 . 26 。 |
| 8. | By evaluating the status of the species and impact of the international trade on the wild population of the species , cites classifies the endangered species in three distinct appendices . any international trade in specimens of species included in the cites appendices should be regulated by each party by issuing and examining a permit or certificate
Cites通过评估物种现状及其发展趋势和国际贸易对物种野生种群的生存所产生的影响，分别将濒危物种列入三个附录，采用由各缔约国核发和查验许可证或证明书的办法，对其国际贸易进行严格管理。 |
| 9. | Both have been on the verge of extinction due to poaching and habitat fragmentation . in order to enlarge the population size and recover the wild populations , ex situ conservation strategy has been advocated by the governing agents in china through natural or artificial breeding in captivity
为了拯救此二物种，我国政府主管部门相继制定了人工易地保护的物种保护策略，以期通过人工圈养条件下的自然繁殖和人工繁殖，达到增加种群的数量，促进野生种群恢复之目的。 |
