The phenomenon of sudden drought after pluvial (or heavy pluvial after drought) is known as the Dry–Wet Abrupt Alternation (DWAA). This kind of disaster has been evaluated globally based on various DWAA indices. However, few validations have been performed to compare the various DWAA indices. Given that directly validating the identified DWAA events remains difficult because of the limited historical records of DWAA events, in...

In order to study the genetic structure and population geographic distribution pattern of coastal mussel populations in the coast of China, mitochondrial DNA (COI and Cytb genes) were used to analyze the genetic diversity, genetic structure, and population history dynamics of Mytilus unguiculatus in the East China Sea and the Yellow Sea. We detected high levels of genetic diversity in seven populations of M. unguiculatus. A to...
