Biodiversity
It is the percentage of the quadrat area that is covered by one species (eg grass).
What is percentage cover?
This group predominates in stable or predictable environments where resources are used for maximising long-term survival
K-strategists
A group of organisms that can interbreed to produce fertile offspring
What is a species?
The variable that goes on the x-axis?
What is the independent variable?
When you make an idea or situation plain or clear by describing it in more detail or revealing relevant facts; give an account; provide additional information.
What is explain?
This number represents the probability that two individuals selected from a sample will belong to different species.
What is SDI?
This type of relationship is when one organism hunts, captures, and consumes another organism.
What is a predator / prey relationship?
the number of individuals in a population
What is abundance?
This classification system defines structural forms of vegetation in terms of the dominant plant form and the percentage of foliage cover of the tallest plant layer.
What is Specht's classification system?
When you display recognition of differences by deliberate juxtaposition of contrary elements; or show how things are different or opposite.
What is contrast?
It is how we would describe organisms living in and on a decaying log.
What is a community?
These organisms prioritise high reproductive rates in environments where resources are abundant, but individual survival and parental care might be lower.
What are r-strategists?
This is a small, localised environment that can vary significantly from the surrounding area in terms of temperature, moisture levels, light exposure, and other environmental factors. An example would include the space under a rock.
What are Microhabitats?
The type of sampling that breaks complex ecosystems and large populations down into homogenous subgroups or strata.
What is stratified sampling
When you obtain a numerical answer showing the relevant stages in the working.
What is calculate?
Which 2 measures does SDI take into account?
Species richness and species evenness
Mutualism, Commensalism, Parasitism are types of this long-term relationship between two different species.
What is symbiosis?
This is the one factor that distinguishes a community from an ecosystem.
What is the abiotic environment?
One is a long strip of terrain in which all organisms are counted and/or measured. The other counts the number of individuals that lie on a straight line that cuts through a community.
What is the difference between A belt transect and A line transect?
When you examine or consider something in order to explain and interpret it, for the purpose of finding meaning or relationships and identifying patterns, similarities and differences.
What is analyse?
Environmental factors that can limit the distribution and abundance of species in an ecosystem. Meaning each organism has their own range that restricts where that organism could potentially live.
What are tolerance limits?
The major taxa in Linnaean Classification
What are Kingdom, Phylum, Class, Order, Family, Genus, Species
Samples determined using a predetermined mathematical pattern.
What is systematic sampling?
Size and number of samples, random-number generators, counting criteria, calibrating equipment and noting associated precision
What are strategies to minimise bias?
When you derive or conclude something from evidence and reasoning, rather than from explicit statements.
What is infer?
