In order to understand and identify key issues of food waste and find potential solutions for food waste minimization in food service business, both a questionnaire and a qualitative study were conduc...
Terrestrial support of zebra mussels and the Hudson River food web: A multi-isotope, Bayesian analysis
Terrestrial support of zebra mussels Hudson River food web A multi-isotope Bayesian analysis
2014/4/2
The Hudson River is a strongly heterotrophic system in which the invasive zebra mussel (Dreissena polymorpha) comprises >90% of total metazoan biomass. Using a Bayesian mixing model, with isotope rati...
Random Sequential Generation of Intervals for the Cascade Model of Food Webs
food chain asymptotic length Poisson approximation Sequential interval generation
2011/7/6
The cascade model generates a food web at random. In it the species are labeled from 0 to $m$, and arcs are given at random between pairs of the species. For an arc with endpoints $i$ and $j$ ($i
The chaos and control of food chain model using nonlinear feedback
Food chain Limit cycles Chaotic behavior
2010/9/10
This paper studies the chaos and control of a continuous time food chain model which contains one prey, one predator and super-predator. We show that this system can be asymptotically stabilized using...
Existence and Global Attractivity of Periodic Solutions in $n$-Species Food-Chain System with Time Delays
Time delay Periodic solution Global attractivity
2008/7/1
A delayed periodic n-species simple food-chain system with Holling type-II functional response is investigated. By means of Gaines and Mawhin's continuation theorem of coincidence degree theory and by...
Periodic Solution of a Nonautonomous Diffusive Food Chain System of Three Species with Time Delays
diffusive food chain system positive periodic solution
2007/12/11
By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for a nonautonomous diffusive food chain system of three species. { dx_1(t)/dt = x_1(t)[r_...
