Parameter Estimation for an Allometric Food Web Model
نویسندگان
چکیده
We present a preliminary attempt at applying an Allometric Trophic Network (ATN) model to single-season population data from agricultural fields. We describe the population dynamics of Rhopalosiphum padi, an aphid pest species, using predator-prey interactions that depend on the relative body masses of species in the food web. Using simple statistical assumptions, we formulate an inverse problem on the ATN model to be solved using field data. Although initial treatment of the inverse problem yielded mixed results across data sets, we identify aspects of the statistical and mathematical models that must be reformulated in future attempts at parameter estimation for the allometric food web model.

Development of an allometric model to estimate above-ground biomass of forests using MLPNN algorithm, case study: Hyrcanian forests of Iran
This research develops an allometric model for estimation of biomass based on the height and DBH of trees in the Hyrcanian forests of Iran. An accurate allometric model reduces the uncertainty of allometric equation in biomass estimation using radar images. In this study, 317 trees were selected randomly from the 4 different dominant tree species for the development of an allometric model cover...
متن کاملPredicting trophic relations in ecological networks: a test of the Allometric Diet Breadth Model.
Few food web theory hypotheses/predictions can be readily tested using likelihoods of reproducing the data. Simple probabilistic models for food web structure, however, are an exception as their likelihoods were recently derived. Here I test the performance of a more complex model for food web structure that is grounded in the allometric scaling of interactions with body size and the theory of ...
متن کاملInvestigation of the Allometric Models in Estimation of Poplar (Populus deltoides) Height
One of the most important issues in forest biometrics is the use of allometric functions to estimate the tree height by using diameter-height models. Measuring the total height of trees is usually a complex and time-consuming process. In allometric functions, the diameter is measured directly but the height of the tree is an estimate of an allometric model, which will be more accurate if the cr...
متن کاملThe Probabilistic Niche Model Reveals the Niche Structure and Role of Body Size in a Complex Food Web
The niche model has been widely used to model the structure of complex food webs, and yet the ecological meaning of the single niche dimension has not been explored. In the niche model, each species has three traits, niche position, diet position and feeding range. Here, a new probabilistic niche model, which allows the maximum likelihood set of trait values to be estimated for each species, is...

An important problem in nonlinear science is the unknown parameters estimation in Loranz chaotic system. Clearly, the parameter estimation for chaotic systems is a multidimensional continuous optimization problem, where the optimization goal is to minimize mean squared errors (MSEs) between real and estimated responses for a number of given samples. The Bees algorithm (BA) is a new member of me...
