A theory that tries to predict how species diversity will change with varying levels of disturbance. interspecific competition A form of competition that occurs between individuals of different species, e.g. when different species try to use the same resources in an environment. Contrast intraspecific competition. intertidal zone
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Metapopulation models simplify the landscape into patches of varying levels of quality, [58] and metapopulations are linked by the migratory behaviours of organisms.

[3] In classical literature this refers to writing about a place or places, what is now largely called 'local history'. In Britain and in Europe in general, the word topography is still sometimes used in its original sense. [4]
The disturbance in matrix A is homoscedastic; this is the simple case where OLS is the best linear unbiased estimator. The disturbances in matrices B and C are heteroscedastic. In matrix B, the variance is time-varying, increasing steadily across time; in matrix C, the variance depends on the value of . The disturbance in matrix D is ...
