Ecological diversity includes the variation in both terrestrial and aquatic ecosystems. Ecological diversity can also take into account the variation in the complexity of a biological community, including the number of different niches, the number of trophic levels and other ecological processes.
What is ecological diversity the measure of quizlet?
Ecological Diversity. Measures variety of biological communities or ecosystems in a given area.
How is ecological measured?
Ecological Footprint accounting measures the demand on and supply of nature. … Both the Ecological Footprint and biocapacity are expressed in global hectares—globally comparable, standardized hectares with world average productivity. Each city, state or nation’s Ecological Footprint can be compared to its biocapacity.
What are the three measures of diversity?
Whittaker (1972) described three terms for measuring biodiversity over spatial scales: alpha, beta, and gamma diversity. Alpha diversity refers to the diversity within a particular area or ecosystem, and is usually expressed by the number of species (i.e., species richness) in that ecosystem.
What is ecosystem diversity examples?
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. … An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans.
What are the ecological implications of global warming?
Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought.
What does ecological stand for?
: of or relating to the science of ecology or the patterns of relationships between living things and their environment There was no ecological damage.
What does an ecological footprint measure quizlet?
The ecological footprint measures humanity’s demand on the biosphere in terms of the area of biologically productive land and sea required to provide the resources we use and to absorb our waste. A measure of the impact/demand humans have on the environment is called an ecological footprint.
How do you quantify the ecological footprint and biocapacity?
Biocapacity is measured by calculating the amount of biologically productive land and sea area available to provide the resources a population consumes and to absorb its wastes, given current technology and management practices.
Why biodiversity is measured?
Biodiversity is a measure that combines richness and evenness across species. It is often measured because high biodiversity is perceived a synonymous with ecosystem health. … Some species work together so that both can survive (called commensalism) and therefore, diverse communities can be more stable.
