Fate of NPs in the aquatic food chain. Download Scientific Diagram
Loladze et al. (2000) formulated a producer-consumer Lotka-Volterra type model (LKE model) of the first two trophic levels of an aquatic food chain (algae-Daphnia) incorporating the fact that both producers and consumers are chemically heterogeneous organisms composed of two essential elements, carbon (C) and phosphorus (P). The model allows the phosphorus to carbon ratio (P:C) of the.

Dynamic model for tritium transfer in an aquatic food chain. Radiat Environ Biophys2011 Aug;50 (3):459-73. doi: 10.1007/s00411-011-0362-. Epub 2011 Apr 17. Tritium ( (3)H) is released from some nuclear facilities in relatively large quantities. It is a ubiquitous isotope because it enters straight into organisms, behaving essentially.

the hypothesis that food chain length should increase with increasing ecosystem size (Schoener 1989, Vander Zanden et al. 1999, Post et al. 2000). Pimm and Lawton (1977) took a very different approach by examining the stability of mathematical food chain models, and found that long food chains tend to be dynamically unstable, though subsequent.

The NPZD model represents a simplified version of the various components of an aquatic food web. These components are nutrients (N), phytoplankton (P), zooplankton (Z), and detritus (D). The model also includes rate factors that affect the aquatic food system, listed in the sliding bars on the right side of the model.

Abstract. In the present paper, we report the effect of nanoparticles in a three-species aquatic food chain model. It is assumed that due to the unavoidable interactions with nanoparticles, the growth rate of basal prey reduces. Fascinating dynamical scenarios in the model are explored in different bi-parametric spaces.

The updated model presented here is based on more standardized, comprehensive assessments than previously used for the aquatic food chain, including the benthic flora and fauna, with an explicit application to the Danube ecosystem, as well as an extension to the special case of dissolved organic tritium (DOT).

In the present study, an updated model of dynamic tri-tium transfer in the aquatic food chain (AQUATRIT model) is presented, using more comprehensive assess-

The objective of this paper is to study the dynamical behavior of an aquatic food chain system. A mathematical model that includes nutrients and harmful phytoplankton and zooplankton is proposed and analyzed. The phytoplankton produces a toxic substance as a strategy of defense against predation by zooplankton.

The software tool POSEIDON-R was developed for modelling the concentration of radionuclides in water and sediments as well as uptake and fate in the aquatic environment and marine organisms. The software has been actively advanced in the aftermath of the Fukushima Dai-ichi accident. This includes development of an uptake model for the benthic food chain, a kinetic-allometric compartment model.

Feeding relationships within a community vary from very simple and rare food chains to highly complex and common food webs. Although most aquatic invertebrates are feeding generalists or omnivores (eating a diversity of organisms) when you consider their entire life cycles, scientists often group them into different trophic levels, such as producer, herbivore (consumer of algae or plant tissue.
