We embedded a well-established physiological model of phytoplankton growth within an ecosystem model of nutrient and DOC supply to assess how simulta-neous changes in DOC and nutrient loads could impact pelagic primary production in lakes.

Webb23 sep. 2024 · Both lake productivity and waterbird FD displayed strong geographical variations across northern China (Figure 3). We found that the geographic position exerted effects on lake productivity and waterbird FD in a similar way, that is, through its influences on climatic conditions, which was defined by seven bioclimatic variables in … Webb10 sep. 2015 · 1. Oxygen measurement: Since there is a definite equivalence between oxygen and food produced, oxygen production can be a basis for determining productivity. Oxygen measurement has been used as a measure of productivity primarily for the aquatic ecosystems. A variety of techniques are employed as listed as … WebbIn lakes and other confined continental water bodies primary production is tightly controlled by the input of nutrients, and a scale of trophic status can be constructed as a function of either surface phosphorus or chlorophyll levels, since both variables correlate. 9 The load of nutrients, normally P, that the water body can admit is easily modelled as a … dijual mobil
