anseriformes 中文意思是什麼
anseriformes
解釋
雁形目-
1. because the taxonomic division is rather complex and has been much disputed and revised, in this part, we will review the classification and phylogeny of families, subfamilies and tribes of anseriformes based on morphology, ethology, osteology, mitochondrial and nuclear dna restriction fragment length polymorphism, single - copy nuclear dna hybridization and the sequences of mitochondrial gene analysis referring to the different definition, classification and phylogenetic relationships of the families, subfamilies and tribes of anseriformes. the controversial questions and deficiency in the systematic studies of anseriformes were pointed out
具體包括以下幾個部分： 1 、針對雁形目鳥類異常復雜的分類狀況及分類上存在的爭議，根據雁形目鳥類的形態學、行為學、骨骼學、角蛋白、線粒體與核dna酶切片段長度多態、單拷貝核dna - dna雜交及線粒體基因dna序列分析等方面的研究，對雁形目鳥類分類中科、亞科和族的劃分及其相互間的系統發生關系進行綜述，分析系統學研究中存在的不足，提出了雁形目鳥類分類中急需解決的問題。 -
