title: Salinity significantly affects methane oxidation and methanotrophic community in Inner Mongolia lake sediments
abstract: Methanotrophs oxidize methane (CH<sub>4</sub>) and greatly help in mitigating greenhouse effect. Increased temperatures due to global climate change can facilitate lake salinization, particularly in the regions with cold semiarid climate. However, the effects of salinity on the CH<sub>4</sub> oxidation activity and diversity and composition of methanotrophic community in the sediment of natural lakes at a regional scale are still unclear. Therefore, we collected lake sediment samples from 13 sit
