Population ecology Virtual Lab I

A population is a collection of individuals of the same species that live together in a region. Population ecology is the study of populations (especially population abundance) and how they change over time. Crucial to this study are the various interactions between a population and its resources. Studies on simple models of interacting species is the main focus this simulation oriented lab. Lab I focuses on introduction of principles of population ecology for UG/PG students.

Population with Continuous and Discrete Growth
In discrete breeding population the species may breed only at a specific time usually at a particular time of the year. Breeding seasons introduce some delay in the regulative process. A population growth model may be defined as continuous population grow
Spread of a Pest Population - Population Invasion
Invasive pest population is one of the serious threats faced in population ecology. Pests are likely to get introduced into an area through transportation and if they find suitable environmental conditions, they start to exploit the resources and spread a
Age Structured Leslie Matrix
Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology. It was invented by and named after P. H. Leslie. The Leslie Matrix (also called the Leslie Model) is one of the best known ways to describe
Stage Structured Leslie Matrix
Stage structured Leslie matrix are used when individuals are censused (rather than marked from after the birth) and the age of individual cannot be known for some reason. In such population individuals are described by size classes (e.g., fishes, deer, fr
Metapopulation Dynamics -Levins Model
Metapopulation is a population in which individuals are spatially distributed in a habitat to two or subpopulations. Populations of butterflies and coral-reef fishes are good examples of metapopulation .
Interspecific Competition and Coexistence
Major focus in community ecology is about understanding the factors underlying species coexistence (Carrete et al). When dealing with competition between native and exotic species, the competitive exclusion of the ‘weaker’ species can have consequence
Effect of Interspecific Competition on Species Border
Interspecific competition refers to the competition between individuals of different species for some limiting resource.
Logistic Population Growth: Continuous and Discrete
The density of population increases until it reaches a maximum sustainable density that is set by the availability of resources. This upper limit to population growth, called the carrying capacity. Populations in this kind of environment show what is know
Parasitoid-Host Dynamics
In this exercise,you will explore two parsitoid-host dynamics models that differ in their description of the dispersion pattern of the host population. The first model is the negative binomial model and second is the Nicholson-Bailey model.
Conserving an Endangered Species
To study the dynamics of an endangered species to develop and apply suitable management plans to recover or repopulate such animals.
