What are some of the environmental factors that cause the formation of rocky coasts?
Environmental factors that influence communities on a rocky shore include desiccation, temperature, wave action, light intensity, aspect, slope and the nature of the substrate. on the chemical composition of sea water.
What are 5 major abiotic factors in rocky shores?
Abiotic factors include temperature, dissolved oxygen, PH, location, and salinity (Bertness). Both abiotic and biotic factors affect the diversity of organisms within a tide pool.
How does wave action affect rocky shores?
Wave action plays a major role in the composition of rocky littoral and sub-littoral communities shores (Lewis, 1964; Hiscock, 1983; Raffaelli and Hawkins, 1996). … Wave action, however, can increase wetting of upper shore species, nutrient supply for algae and suspended food for filter feeders.
How are muddy shores formed?
Muddy shores are formed along the seashores where there is no or little wave action. These intertidal areas are formed by the deposition of silt from the water flowing into the sea. Muddy shores are quite common along the sheltered beaches, estuaries and mangroves.
How do humans affect rocky shores?
Increasingly, humans visit the rocky shore as naturalists and sightseers, to collect bait and “souvenirs,” and to harvest food. … Other more recent studies, have also detected density and species composition changes associated with human use (Duran et al. 1987, Underwood and Kennelly 1990, Kingsford et al.
What are the biotic factors of a rocky shore?
Biotic factors in an ecosystem are related to the living parts of that system and include competition for resources, predation, herbivory, parasitism and mutualism. The lower vertical distribution limit for most intertidal species is determined by interspecific competition, food availability and predation pressure.
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
How does temperature affect organisms on rock platforms?
Organisms are exposed to the drying heat of the sun in the summer and to low temperatures in the winter. … The algae growing higher on the rocks gradually die when the air temperature changes. At the lower edge of the splash zone, rough snails (periwinkles) graze on various types of algae.
