    在火燒地，大鴇會選擇植物種類數較多、蓋度較大、裸地比例較小及植株相對較高處進行求偶炫耀；在非火燒地，枯草比例、貝加爾針茅密度及枯草厚度是影響其求偶場選擇的重要因素。

  16. The 301 - 330bp hypervariable ii - control - region sequence in mitochondrial ( mt ) dna genome from 18 individuals of one subspecies of great bustard ( o. t. dybowskii ) from breeding areas of northwest of songliao plain, southwest of hulunbeier plateau and wintering area of shandong yellow river nature reserve in china were sequenced and population analysis was conducted to assess the level of genetic diversity
