Based on physiological similarities we hypothesize that mistletoes and albino shoots should display similar nutrient relationships to their host tissues and act as nutrient traps.
Furthermore, the weak individual nutrient relationships were not due to lack of consideration of curvilinear relationships as we analysed for both high and low consumption.
Monitoring data from 28 ecosystems located in four well-studied regions were analyzed to study the generality of chlorophyll a versus nutrient relationships and their applicability for ecosystem management.
A potential interpretation of the response (Fig. 1b) is that it is the signal of a temperature-nutrient relationship: surface nutrients decline with increasing temperature above ∼15°C, although the details of this relationship vary with latitude [44].
In the simplest possible case of information limitation in only one nutrient, the relationship between cell growth and information (in bits) is best expressed as -log2(s) = I+1, where s is a selection coefficient, the difference between the maximal growth rate with perfect sensing and the actually attained growth rate.
Second, specifically up-regulated proteins may have evolved to be nutrient-poor, resulting in a negative expression-nutrient content relationship only in up-regulated proteins [ 3, 20].
The DLMV was the only study area that demonstrated the commonly predicted nutrient-biomass relationship with a sufficient gradient from low to high nutrients (Fig. 2e).
Nutrient concentration flow relationships for monitoring sites along the River Thames and 15 of its major tributaries were used to estimate the relative inputs of phosphorus and nitrogen from continuous (sewage point sources) and rain-related (diffuse and within-channel) sources, using the Load Apportionment Model (LAM).
Our mechanistic understanding of eutrophication processes has evolved in parallel from simple nutrient-driven relationship to complex models involving various trophic levels and ecosystem-specific features.
Nutrient "dose response" relationships mainly cover intakes producing nutrient deficiencies, nutrient optimal activity, and preservation of nutrient safety with excess intakes rather than global, combined dose-responses that define nutrient essentiality as a small early portion of a mainly dose toxicity curve.
