Symbiotic relationships of legumes and nodule bacteria on Barro Colorado Island, Panama: a review.

abstract：:Heterotrophic bacteria are, in many aquatic systems, reliant on autochthonous organic carbon as their energy source. One exception is low-productive humic lakes, where allochthonous dissolved organic matter (ADOM) is the major driver. We hypothesized that bacterial production (BP) is similarly regulated in subarctic e...
