Response of total and nitrate-dissimilating bacteria to reduced N deposition in a spruce forest soil profile.

abstract：:In eastern Canada, climate change-related warming and increased precipitation may alter winter snow cover, with potential consequences for soil conditions, nitrogen (N) cycling, and microbes. We conducted a 2-year field study aimed at determining the influence of snow removal, snow accumulation, and ambient snow in a ...
