The molecular mechanisms underlying the adaptation to freshwater habitats in fish of marine origin remain unclear. Grenadier anchovies, such as Coilia nasus , originate from marine environments and include both anadromous and freshwater‐resident conspecifics, making them ideal for studying adaptive evolution from marine to freshwater habitats. We conducted a comparative population genomic and transcriptome analysis of two dist...

Introduction The carbonate-evaporite system contains substantial hydrocarbon resources and serves as an excellent subject for studying dolomitization problem. In the Ordos Basin, the fifth member of the Ordovician Majiagou Formation have extensive carbonate-evaporite deposits. Methods This study utilizes extensive drilling data, thin section microscopic examination, scanning electron microscopy, and a variety of geochemical an...
