Population and Community Ecology

What are Populations and Communities?
Overview Populations are groups of individuals of the same species that inhabit a shared environment. Communities include multiple co-existing,…
Distribution and Dispersion
28.2: Distribution and Dispersion
To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic…
Life Histories
28.3: Life Histories
Overview Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off…
Energy Budgets
28.4: Energy Budgets
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of…
Population Growth
28.5: Population Growth
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with…
Symbiosis
28.6: Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of…
Environment: Manipulating Plant-induced Soil Heterogeneity
28.8: Environment: Manipulating Plant-induced Soil Heterogeneity
One of the primary goals of community ecology is to predict the processes governing environmental assembly to successfully restore native diversity.…
Bioengineering: Assembly and Tracking of Microbial Community Development within a Microwell Array Platform
28.9: Bioengineering: Assembly and Tracking of Microbial Community Development within a Microwell Array Platform
The development of microbial communities depends on environmental architecture, abundance of members, traits and interactions. This protocol…
Environment: Empirical, Metagenomic, and Computational Techniques Illuminate the Mechanisms by which Fungicides Compromise Bee Health
28.10: Environment: Empirical, Metagenomic, and Computational Techniques Illuminate the Mechanisms by which Fungicides Compromise Bee Health
Although considered safe, there is mounting evidence that fungicide on crops is associated with the decline of bees. This protocol uses next…
