Mike C Rowley et al.
Organo-mineral and organo-metal associations play an important role in the retention and accumulation of soil organic carbon (SOC). Recent studies have demonstrated a positive correlation between calcium (Ca) and SOC content in a range of s...
Microbial responses to soil cooling might explain increases in microbial biomass in winter [0.03%]
土壤冷却引起的微生物响应可能解释了冬季微生物生物量的增加
Jörg Schnecker,Felix Spiegel,Yue Li et al.
Jörg Schnecker et al.
In temperate, boreal and arctic soil systems, microbial biomass often increases during winter and decreases again in spring. This build-up and release of microbial carbon could potentially lead to a stabilization of soil carbon during winte...

Nolan J T Pearce et al.
River-to-lake transitional areas are biogeochemically active ecosystems that can alter the amount and composition of dissolved organic matter (DOM) as it moves through the aquatic continuum. However, few studies have directly measured carbo...
Transitions in nitrogen and organic matter form and concentration correspond to bacterial population dynamics in a hypoxic urban estuary [0.03%]
