1 New Zealand's critically endangered kakspōs have begun to return to the country'smainland for the first time in almost 40 years. Kakapōs are the heaviest parrots in theworld, with some more than six pounds, and they have a lifespan of up to 90 years. Theycan't fly, so kakapōs climb trees and search on the ground for nuts and seeds to eat. The bigbirds used to be widespread across New Zealand, but were hunted to near extinction. Popu?lar Science described these“ curious” birds as already being“ doomed to early extermination”all the way back in April 1895.
2 The roughly left 250 or so individualbirds are managed by New Zealand's Department of Conservation(DOC) on five islands that are free of enemies.Now equipped with genetic science,research platform Genomics Aotearoais funding high?quality genetic sequencing(基因测序) of almost the entire kakapō population.
3 Establishing genetic sequencing methods is expected to not only play a part inkakapōs' survival, but also other endangered species' survival throughout theworld. Conservation genomics (基因组学) is part of a growing trend in the field. In 2019, ateam from the University of Hawaii used advanced DNA sequencing technology to create anearly complete genome assembly (基因組装) for Hawaii's only remaining family of thecrow family alal'. The sequencing gave conservationists critical clues into the disease susceptibility (易感性), population?level diversity, and genetic load of the alal' to betterinform their policies.
4 The same information could help the kakapō thrive. This work over the last year hasproduced two very significant outcomes. First, it has given the team an in?depth understandingof kakapō biology. It has also produced a high?quality code and reusable pipeline,which allows other researchers to rapidly use these methods in their own work.
“5 Kakapōs suffer from disease and low reproductive output, so by understanding thegenetic reasons for these problems, we can now help mitigate them,” Andrew Digby, theDOC's Science Advisor for Kakapō Recovery, said in a statement.“ It gives us the abilityto predict things like kakapō chick growth and susceptibility to disease, which changesour on?the?ground management practices and will help improve survival rates.”

Ⅱ. 语句分析
1. Establishing genetic sequencing methods is expected to not only play a part inkakapōs' survival, but also other endangered species' survival throughout the world. 建立基因测序方法不仅仅是为了鸮鹦鹉的生存,也是为了世界上其他濒危物种的生存。
【点石成金】本句中,Establishing genetic sequencing methods是动名词形式作主语。
2. It gives us the ability to predict things like kakapō chick growth and susceptibilityto disease, which changes our on?the?ground management practices and will help improvesurvival rates. 它使我们能够预测鸮鹦鹉雏鸟的生长和对疾病的易感性,这也改变了我们的实地管理实践,有助于提高存活率。
【点石成金】本句是一个主从复合句,主句中的to predict things like kakapō chickgrowth and susceptibility to disease 是不定式作后置定语;which 引导非限制性定语从句。
