Investigating abundance and distribution Flashcards
abundance
the relative representation of a species in a particular ecosystem
distribution
where a species of organism is found in the environment and how it is organised
quadrat
a sample area used in practical ecology, often measured using a square frame divided into sections that you lay on the ground
individual counts
a measure of the number of individual organisms in an area
percentage cover
the area covered by the above-ground parts of a particular species
ACFOR scale
a simple scale used to describe the abundance of a species in a given area
line transect
a way of collecting data more systematically; a tape is stretched between two points and every individual plant (or animal) that touches the tape is recorded
belt transect
when two tapes are stretched out and the ground between them surveyed or a tape stretched out and quadrats are taken at regular intervals
