used a hydrological computer
model to simulate the
ecological impacts of tropical cyclones from 2004 - 2007.
In their food - web
modeling, Sahasrabudhe and Motter have
used accepted
ecological models of predator - prey relationships, but a more elaborate representation of an ecosystem would also include parasitism, seed dispersal, competition, mutualisms (in which species make life easier for each other), nutrient dynamics and more.
But, by
modeling a variety of food webs
using established
ecological principles, the researchers were able to find such species and they hope that the algorithms that they created might eventually be able to identify target species in the real world.
Frey and his colleagues made
use of mathematical
models to analyze the complex interplay between
ecological factors and population dynamics, and were able to demonstrate that populations can indeed respond in a coordinated fashion to chemical information even when the signal molecules are generated by only a subset of the cells.
They then
used a
modeling approach developed by Scripps ecologist George Sugihara and colleagues to detect cause - and - effect relationships in
ecological systems.

use microorganisms as a
model in
ecological experiments.»

ecological need of the forests, McKinnon added, it must
use really small wood, which is not in Pioneer's business
model.
Scientists
use model organisms to study critical biological processes, but Egan said the study of nonmodel organisms is often the key to
ecological questions, including those related to how the environment influences natural selection and speciation.

ecological model as a guiding framework, this study explores the individual, interpersonal, organizational, community, and policy factors that impede and facilitate the transition from residential substance abuse treatment from the perspectives of individuals with SUDs who are anticipating discharge from treatment.»
«We can
use these molecules to create predictive
models and see how changes in the environment altered microbial growth patterns and then, in a feedback loop, how these growth patterns affect the environment — how they create a
model of
ecological change.»

used a mathematical
model to show that positive feedback loops between fire frequency and savanna trees, alone or together with grasses, can stabilize

More specifically, researchers led by the University of Idaho's Tara Hudiburg merged the DayCent
