Abstract: Disclosed in the present invention is a fishway effect evaluation method based on stable isotope method, belonging to the technical field of fishway effect evaluation. The fishway effect evaluation method according to the present invention comprises stable isotope ratio determination, trophic niche estimation and effectiveness evaluation on fishway construction. The evaluation method according to the present invention is used for researching one or more migratory fishes in the upstream and downstream of the water conservancy projects, determining and quantitatively explaining whether the influence of the water conservancy projects on one or more migratory fishes is eliminated or not from the perspective of the ecosystem through comparison and analysis of stable isotopes, and has the characteristics of high detection speed, stable result and the like.

Abstract: A non-redundant gene set clustering method and system, as well as an electronic device are disclosed. The method includes: operation a: performing an alignment operation on an original gene set to obtain gene pairs in the original gene set that meet a similarity threshold; operation b: constructing a union-find forest based on the obtained gene pairs; operation c: obtaining gene clustering results of all classes in the original gene set based on the union-find forest; and operation d: based on the gene clustering results, selecting the longest sequence in each class as a representative sequence of the class to obtain a non-redundant reference gene set. According to this application, the non-redundant gene set clustering is performed by using BLAT alignment and based on the disjoint-set data structure, and so can take into account the similarity between more genes and improve the accuracy of de-redundancy.
