Shifts in the bulk soil microbial community induced by climate change may have long lasting effects on plant performance and/or establishment and soil carbon balance In fact the interactions between plants and soil communities such as plant‐soil feedbacks are some of the most important yet least understood controllers of soil nitrogen

Aug 03 2020The microbial community appears to respond differently to natural and human-gradients than eukaryotic indicators despite the ability to predict stream condition Animal taxa show decreasing richness and diversity with subsequent community-level turnover as watersheds lose forest and transition to urban dominated landscapes [27 59]
