EFFECTS OF SECONDARY SALINIZATION ON SOIL PHOSPHORUS FRACTIONS AND MICROBIAL COMMUNITIES RELATED TO PHOSPHORUS TRANSFORMATION IN A MEADOW GRASSLAND, NORTHEAST CHINA

Soil microorganisms play key roles in soil phosphorus (P) mobilization in grassland ecosystems.However, little is known about how bacterial communities involved in P transformation respond to soil secondary salinization.In this study, a meadow grassland with a gradient of secondary salinization in the semi-arid Horqin Sandy Land, Northeast China wa

Marine mammals have greatly benefitted from a shift from resource exploitation towards conservation.Often lauded as symbols of conservation success, some marine mammal populations have shown remarkable recoveries after severe depletions.Others have remained at Trunk low abundance levels, continued to decline, or become extinct or extirpated.Here we
