Populations of Agrostis diluta Kurcz. and Psathyrostachys caespitosa (Sukaczev) Peschkova in Yakutia: dynamics of vitality
In Yakutia, natural floodplain meadows and steppes have long been involved in economic activities. To develop methods of rational use, one needs to constantly consider the state of vegetation, mainly its constituent populations. Our research focuses on studying the dynamics of the vitality of the po...
