This contradicts numerous theoretical studies which indicated a primarily tetrahedral coordination structure with a solvation number near 2 or 3, depending on the prevalence of ion pairing.

这与大量的理论研究——一个主要的四面体配位结构是2或3左右，取决于离子对的流动率的溶剂化数是相悖的。

He suggested that females may perceive the song as abnormal if they could not hear the lower frequencies and, over a period of time, this could have a potential impact on the abundance of the species as if adults were not pairing and mating then the number of offspring would decrease as a result.
