Physical diversity describes a variety of physical characteristics and abilities.
Definitions Back to Top A community is the set of all populations that inhabit a certain area. Communities can have different sizes and boundaries. These are often identified with some difficulty. An ecosystem is a higher level of organization the community plus its physical environment.
We can study ecosystems from a structural view of population distribution or from a functional view of energy flow and other processes. Community Structure Back to Top Ecologists find that within a community many populations are not randomly distributed.
This recognition that there was a pattern and process of spatial distribution of species was a major accomplishment of ecology.
Two of the most important patterns are open community structure and the relative rarity of species within a community. Do species within a community have similar geographic range and density peaks? If they do, the community is said to be a closed communitya discrete unit with sharp boundaries known as ecotones.
An open community, however, has its populations without ecotones and distributed more or less randomly. In a forest, where we find an open community structure, there is a gradient of soil moisture.
Plants have different tolerances to this gradient and occur at different places along the continuum. Where the physical environment has abrupt transitions, we find sharp boundaries developing between populations. For example, an ecotone develops at a beach separating water and land.
Open structure provides some protection for the community. Lacking boundaries, it is harder for a community to be destroyed in an all or nothing fashion. Species can come and go within communities over time, yet the community as a whole persists. In general, communities are less fragile and more flexible than some earlier concepts would suggest.
Most species in a community are far less abundant than the dominant species that provide a community its name: Populations of just a few species are dominant within a community, no matter what community we examine.
Resource partitioning is thought to be the main cause for this distribution. Classification of Communities Back to Top There are two basic categories of communities: These two basic types of community contain eight smaller units known as biomes.
A biome is a large-scale category containing many communities of a similar nature, whose distribution is largely controlled by climate Terrestrial Biomes: Terrestrial biome distribution is shown in Figure 1.
Image from Purves et al. Terrestrial Biomes Tundra and Desert The tundra and desert biomes occupy the most extreme environments, with little or no moisture and extremes of temperature acting as harsh selective agents on organisms that occupy these areas.
These two biomes have the fewest numbers of species due to the stringent environmental conditions. In other words, not everyone can live there due to the specialized adaptations required by the environment. Tropical Rain Forests Tropical rain forests occur in regions near the equator.
The rain forest is probably the richest biome, both in diversity and in total biomass. The tropical rain forest has a complex structure, with many levels of life.
More than half of all terrestrial species live in this biome. While diversity is high, dominance by a particular species is low. Typical tropical rain forest views are shown in Figure 2. While some animals live on the ground, most rain forest animals live in the trees. Many of these animals spend their entire life in the forest canopy.
Insects are so abundant in tropical rain forests that the majority have not yet been identified.Religious diversity is an important component of cultural diversity, which educators are now taking seriously in their pedagogies.
However, cultural diversity and religious diversity . Oct 10, · Autism spectrum disorder is diagnosed by clinicians based on symptoms, signs, and testing according to the Diagnostic and Statistical Manual of Mental Disorders-V, a guide created by the American Psychiatric Association used to diagnose mental disorders.
Physical Signs That Show There Is Diversity Within Your Community. Certificate in Equality and Diversity Unit 1: Exploring Equality and Diversity Assessment You should use this file to . In community life, there’s a progression from Seeing to Knowing to Talking to Trusting to Action; and the “talking” part, or interaction, is a basic link in that chain.
Creating good places for interaction should always be kept in mind. statues, murals, etc. in a variety of languages and representing the diversity of the community. Nov 11, · The first four articles covered a high-level overview of why diversity is powerless without inclusion, and how to create an inclusive approach to your workforce and to your consumer experience.
Jean Snell, clinical professor of teacher education at the University of Maryland, believes cultural diversity enhances the school experience, too. “There is a richness that comes from students working side by side with others who are not of the same cookie-cutter mold,” she notes.
