Abstract:
... We explore the hypothesis that intraspecific trait variability can be per se beneficial for the plant when the curvature of the herbivore response to this trait is concave downwards. This hypothesis is based on a mathematical relation for nonlinear averaging (Jensen’s inequality), leading to reduced herbivory when the trait distribution becomes broader. Our study introduces and investigates a mode ...

Abstract:
... Growth plasticity may allow fire‐prone species to maximize their recovery rates during temporary, sporadic periods of rainfall availability in the post‐fire environment. However, moisture‐driven growth plasticity could be maladaptive in nutrient‐limited environments that require tighter control of growth and resource use. We investigated whether a trade‐off between plasticity and conservatism medi ...

Abstract:
... Lifestyle and genetic perturbation of circadian rhythm can trigger the incidence and severity of metabolic diseases. Time-restricted feeding (TRF) regulates the circadian rhythm of food intake that protects against metabolic disorders induced by adverse nutrient intake. TRF also executes host metabolism from nutrient availability to optimize nutrient utilization. Circadian clock and nutrient-sensi ...

Abstract:
... While the results of Acanthamoeba testing have been extensively published, laboratories conducting such testing are left to develop their own methods in the absence of a standardized methodology. The wide disparity of methods has resulted in equally inconsistent reported results for contact lens care (CLC) products. This study’s objective was to determine the source of these discrepancies by evalu ...

Abstract:
... Plant nutrition practice in organic agricultural systems is sometimes reduced to a renunciation of applying readily soluble mineral fertilisers. In organic farming, however, soil nutrient stocks are regarded as an additional source of plant-available nutrients that can be mobilised by crop plants through rhizosphere effects. Therefore, unlike in conventional farming, the focus is not on replacemen ...

Abstract:
... The nitrogen (N) vs. phosphorus (P) scaling exponent, which reflects the trade-off between N and P investment, is an important parameter for predicting plant growth and vegetation productivity. Previous studies mainly focused on a single metabolic organ, and the difference in scaling exponents among different organs was insufficiently discussed. We systematically sampled 1532 shrub individuals gro ...

Abstract:
... Living shoreline marshes are coastal wetlands constructed as alternatives to “hardened shorelines” (e.g., bulkheads, riprap) to mitigate erosion and to allow for landward migration of intertidal habitat as sea level rises. Living shorelines are designed to mimic natural fringing marshes and over time should be sinks for carbon and other nutrients. We collected soil cores and aboveground plant mate ...

When included into an architectural root model, this local model has to be solved for a high number of root segments, e. g. 105 – 106 segments for large root systems. Each root segment comes with its own local parameter set in heterogeneous root architectural ...

Abstract:
... Establishing tributary load (i.e., the mass exported over a period of time) targets to reduce anthropogenic nutrient inputs to receiving waters — and thus eutrophication — is a common mitigation strategy in freshwater and coastal ecosystems. However, detecting and quantifying trends can be difficult because annual precipitation strongly influences tributary flow (e.g., average daily stream dischar ...
