Land Changes

Processes in rocky coasts operates in a wide range of time-scales, from seconds to millennia, but sealeveloscillations probably are the most significant changes. A portion of land changes from coastal tocontinental environment as sea-level rise or fall, and, although a re-occupied coast is never the same, itcan conserve a memory of the previous morphodynamic states. This memory of the system implies thatthe processes that operated in the past exert a large influence on present processes. This is a veryimportant factor in the evolution and present dynamics of rocky coasts, in which many erosive andsedimentary landforms are fully or partially inherited.

Test Cultures

An alternative test is presented, in which algal cultures are used for testing toxic substances. This test system is based on variations in the size distribution of cells in test cultures as a measurement of growth. Thus, inhibition of mitotic activity is used as a measurement for toxic effects. The test can be performed on a short time-scale and is very sensitive to even weak toxic doses.
