Accuracy of numerical methods for solving the advection–diffusion equation as applied to spore and insect dispersal

Autor: Merry E. Makela, Lloyd T. Wilson, Yubin Yang, M. A. Marchetti

Publikováno v: Ecological Modelling. 109:1-24

Three algorithms for solving a simplified 3-D advection–diffusion equation were compared as to their accuracy and speed in the context of insect and spore dispersal. The algorithms tested were the explicit central difference (ECD) method, the impli

Predicting Sorghum Midge (Diptera: Cecidomyiidae) Generations and Abundance

Autor: Bonnie B. Pendleton, George L. Teetes, Merry E. Makela

Publikováno v: Journal of Economic Entomology. 87:993-998

A total of 39,687 assessments of abundance of ovipositing sorghum midge, Contarinia sorghicola (Coquillett), and sorghum, Sorghum bicolor (L.) Moench, spikelets in flower were used to evaluate, refine, and validate a sorghum midge population dynamics

Inclusion of plant structure and fiber quality into a distributed delay cotton model to improve management and optimize profit

Autor: K. M. El-Zik, Merry E. Makela, Nicholas D. Stone, Mark J. Cochran, Ronaldo Antonio Sequeira

Publikováno v: Ecological Modelling. 71:161-186

This research introduces a simple variation of distributed delay algorithms to solve some relevant problems in simulation of plant development. Cotton was used as a case study. An energy-based model of cotton plant growth was expanded to account for

An object-oriented intracolonial and population level model of honey bees based on behaviors of European and Africanized subspecies

Autor: G. A. Rowell, Merry E. Makela, Lloyd T. Wilson, W. J. Sames

Publikováno v: Ecological Modelling. 67:259-284

A computer-based simulation model of a population of honey bee colonies, based on the biology of European and African races of Apis mellifera L., is described. The intracolonial dynamics of each colony are simulated each day based on parameters inter

Generation of mechanistic variability in a process-based object-oriented plant model

Autor: K. M. El-Zik, Merry E. Makela, Ronaldo Antonio Sequeira, Nicholas D. Stone, Peter J.H. Sharpe

Publikováno v: Ecological Modelling. 67:285-306

A cotton crop model based on individual plant developmental behavior and variability was developed. Object-oriented simulation (OOS) provided the conceptual basis for the new model structure. The procedural model, COTSIM, provided the theoretical bac

Use of the Gamma Distribution for Predicting Arrival Times of Invading Insect Populations

Autor: William L. Rubink, J. H. Matis, Merry E. Makela

Publikováno v: Environmental Entomology. 21:436-440

Models that describe the distance traveled in a fixed time of a dispersing insect population are well-known. The gamma distribution is presented as a model for the inverse variable, namely the time required to travel a fixed distance. The use of the

Object-oriented simulation: plant growth and discrete organ to organ interactions

Autor: K. M. El-Zik, Merry E. Makela, Ronaldo Antonio Sequeira, Peter J.H. Sharpe, Nicholas D. Stone

Publikováno v: Ecological Modelling. 58:55-89

This paper reviews and applies new hierarchical approaches to ecological modelling. These new approaches are made possible by the development of the object-oriented paradigm. This paradigm draws upon the notion of ‘universal’ or classes dating ba

Simulation of Boll Weevil (Coleoptera: Curculionidae) Spring Emergence and Overwintering Survival in the Texas Rolling Plains

Autor: Merry E. Makela, Raymond E. Frisbie, D. R. Rummel, Nicholas D. Stone, Stan C. Carroll

Publikováno v: Environmental Entomology. 19:91-98

A degree-day model of boll weevil, Anthonomus grandis Boheman, spring emergence and survivorship in the Rolling Plains of Texas was developed and validated based on seven years of data that describe emergence rates of cohorts of boll weevils caged in
