	A Guide To Habitats In Ireland
		Littoral, or seashore, habitats are subdivided on the basis of substratum type into two broad sections: littoral rock (hard substrata colonised mainly by epibiota) and littoral sediment (unconsolidated material colonised mainly by infauna).
		Littoral rock includes rocky habitats of the littoral, or intertidal zone that extends from the upper limit of the supralittoral, or spray zone, to the MLWS tide mark.
		The littoral zone is taken as the area between the uppermost limit of the strandline and the MLWS tide mark.

	Ocean Regions: Littoral Zone - Characteristics
		The littoral zone is the part of the ocean closest to the shore.
		The littoral zone is from the shoreline to 600 feet (183 meters) out into the water and is divided into three zones: the supralittoral zone, the intertidal zone and the sublittoral zone.
		The littoral zone is a tricky area for predicting water conditions because so many factors affect it.

	The Intertidal Zone - Abiotic (Site not responding. Last check: 2007-10-16)
		The organisms in the littoral zone must be adapted to both wet and dry conditions.
		Since in the littoral zone, many tides come in and out, there is a lot of turbulence in the water.
		The location matters because the littoral zone can be located anywhere in the world from the coasts of BC to the coasts of New Zealand.

		Jennifer Oakes: Are Ruby and Johnathon in the Zone?
		It seems to me that there is a strong parallel between the description of the littoral zone in scientific terms and the position that Ruby and Johnathon find themselves in.
		The littoral zone is defined as," that space between high and low watermarks where organisms struggledto adapt to the daily rhythm of immersion and exposure." I think that these two characters are also trying to adjust in a space between high practicality and strict scientific ideals, and raw passion and instinct.

		Go to the columns containing the biomass data for the littoral periphyton incubations (at a station near the dock and at the far end of the lake).
		Calculate the dry mass and chlorophyll a/ml in the plankton of the littoral zone (using the light bottle data and the same method as above).

	Joseph Berardino - Decision (Site not responding. Last check: 2007-10-16)
		The ALJ reasoned that the burial of twenty 200 to 500 pound boulders in the littoral zone "...would not lower the beach under water [and] would not alter any waterway...." thus the project would not be in contravention of the standards.
		Absent visible biological growths or vegetation on the rocks proposed to be sunk and absent otherwise in the littoral zone, the mechanisms for cleansing the ecosystem are not present.
		Approximately twenty rocks in the littoral zone beach would be sunk in place by directing a jet of water about them with the intent to cause the rocks to sink in place below the surface of the beach.

	Results and discussion
		The inclination of shoreline or slope is assumed to be a significant factor affecting the diversity of the littoral flora (Duarte & Kalff 1986).
		The littoral is always partly unstable, as waves and currents cause erosion in the upper zone, whereas eroded material accumulates in the lower, deeper zone of the littoral (I).
		The littoral area acts as an ecocline between the terrestrial and aquatic environments and serves as the habitat of aquatic macrophytes.

	Representing Environment Lecture 4 Livingstone: A Littoral Zone (Site not responding. Last check: 2007-10-16)
		Littoral zone: intertidal zone; that part of the ocean closest to the shore; section b2 highest and lowest tide;, home to diverse plants and animals (and as one website put it, “each with a story to tell”.
		At the same time, though, we could conceptualise the littoral zone as a somewhat different environmental metaphor, in which ‘the littoral zone’ is a microcosmic representative of human beings’ engagement with animals, the elements, and people more generally.
		As I have said: A Littoral Zone, L’s final collection before his death in Durban in 1996, uses these 26 stations as the basis for a series of poems mapping his life and identity as a scientist, poet, human being, man, white man – various identities represented in the poems, not necessarily coherent.

	Hoyer/Canfield: Aquatic Plant Management
		Interest in restoring and restructuring macrophyte communities and an appreciation for the littoral zone (littoral zone is that portion of a water body extending from the shoreline lakeward to the greatest depth occupied by rooted plants) is growing.
		The middle littoral zone extends lakeward from the upper littoral zone to water depths of 3 to 9 feet (1 to 3 meters).
		The importance of the littoral zone to whole lake primary productivity (the rate at which algae and macrophytes fix or convert light, water, and carbon to plant tissue in plant cells) varies with the size and volume of the lake and the size of the littoral zone in that lake.

	The Aquatic Biome
		The topmost zone near the shore of a lake or pond is the littoral zone.
		The intertidal zone on sandier shores is not as stratified as in the rocky areas.
		The pelagic zone is generally cold though it is hard to give a general temperature range since, just like ponds and lakes, there is thermal stratification with a constant mixing of warm and cold ocean currents.

		Protecting the littoral zone is important for the health of many of a lake's fish and other animal populations.
		In places where the slope of the lake bottom is steep, the littoral area may be narrow, extending several feet from the shoreline.

	Buffalo Lake Fire Proposal
		The littoral zone of Buffalo lake was reduced from 7+ meters (M) to 2 M. The change was in diversity of the littoral biota as well as in the area formerly occupied.
		A very important affect of littoral zone reduction is less provision of refuges for grazers, especially the large zooplankton.
		The consequence is further reduction of the littoral zone.

	Your Heading Goes Here
		Sediment samples from throughout the littoral zone and from permanently wetted areas will be collected, returned to the mesocosm facility, and cultures established for a array of manipulations.
		Preliminary experiments have shown that a large number of species, primarily rotifers, appear in the cultures that are rarely collected in field samples, particularly from littoral zone sediments, but these observations have not been quantified nor have data been compared with samples from permanently wetted sediments.
		Species in the littoral zone should be limited to those that produce an overwintering egg or cocoon (e.g., oligochaetes) or those that deposit eggs (chironomids) once the littoral zone is flooded.
