Warming changes the composition and diversity of fungal communities in permafrost
Abstract Purpose It is the data support and theoretical basis for the response mechanism of soil fungi to climate warming in permafrost areas in the Greater Xing’an Mountains. Methods We collected permafrost from the Greater Xing’an Mountains for indoor simulation experiments and took the natural pe...
