Important Terms
Range – means the total area occupied by the species of interest in the region under study (see below ‘Which Range’)
Abundance – means the average density of the species of interest across all occupied patches (i.e. average abundance does not include the area of unoccupied patches)
Intraspecific occupancy–abundance relationship – means the relationship between abundance and range size within a single species generated using time series data
Interspecific occupancy–abundance relationship – means the relationship between relative abundance and range size of an assemblage of closely related species at a specific point in time (or averaged across a short time period). The interspecific O-A relationship may arise from the combination of the intraspecific O–A relationships within the region

Famous quotes containing the words important and/or terms:
“How we shall earn our bread is a grave question; yet it is a sweet and inviting question. Let us not shirk it, as is usually done. It is the most important and practical question which is put to man. Let us not answer it hastily. Let us not be content to get our bread in some gross, careless, and hasty manner. Some men go a-hunting, some a-fishing, some a-gaming, some to war; but none have so pleasant a time as they who in earnest seek to earn their bread.”
—Henry David Thoreau (1817–1862)
“It is not stressful circumstances, as such, that do harm to children. Rather, it is the quality of their interpersonal relationships and their transactions with the wider social and material environment that lead to behavioral, emotional, and physical health problems. If stress matters, it is in terms of how it influences the relationships that are important to the child.”
—Felton Earls (20th century)
