Baseline surveys of rocky intertidal ecological resources at Point Loma, San Diego / By John M Engle, Gary E Davis, Geological Survey (U.S.) and United. The objectives of this baseline study of rocky intertidal habitats along the North Coast Study Region (NCSR) are to (1) produce a quantitative baseline characterization of the structure of rocky intertidal ecosystems in Marine Protected Areas (MPAs) established by the Marine Life.

As originally proposed, the project provided for 15 months of rocky intertidal sampling in San Diego, including fall and spring monitoring surveys at five sites along the coast of Point Loma.

The survey methods replicate those developed for the West Coast by scientists with the Multi-agency Rocky Intertidal Network (MARINe). In the project’s first year, scientists completed baseline biodiversity surveys and target-species sampling at 22 sites.

Target-species sampling was continued at these sites during the project’s second year. Engle JM, Davis GE (a) Baseline surveys of rocky intertidal ecological resources at Point Loma, San Diego.

Abstract. The rocky intertidal zone is among the most physically harsh environments on earth. Marine invertebrates and algae living in this habitat are alternatively pounded by waves and exposed to thermal extremes during low tide periods (Denny and Wethey, ).Additionally, they must deal with strong selective pressures related to predation and competition for space (Connell, ).Cited by: San Miguel Is., Crook Point 34 01 ¢ 19 ¢¢ 22 ¢ 44 ¢¢ Straughan and Kanter () San Miguel Is., Cuyler Harbor 34 02 ¢ 54 ¢¢ 20 ¢ 12 ¢¢ Straughan and Kanter ( Characterization of the rocky intertidal ecological communities associated with The upper baseline was placed in the high zone above the upper limit of the organisms, while the lower baseline, which should be parallel to the upper baseline, was Point-Contact Surveys - Each vertical transect was sampled using the point intercept method.

San Diego County is home to a wide range of terrestrial and marine ecosystems found in the vast deserts, on the forested mountains, in the coastal kelp forests, and deep in the submarine canyons. Caught in the middle of the physical clash between land and sea is the highly dynamic ecosystem of the rocky intertidal zone.

The rocky intertidal zone is a unique habitat that is used by a variety of endemic plant and animal species, many of them at the edge of their physical and ecological tolerances.

These species are important food for birds and mammals that forage along the. Environmental stress affects species richness and diversity in communities, but the precise form of the relationship is unclear.

We tested an environmental stress model (ESM) that predicts a unimodal pattern for total richness and diversity in local communities across the full stress gradient where a regional biota can occur.

Inwe measured richness and diversity (considering all Cited by: The Biodiversity Surveys provide detailed information about biodiversity and community structure.

These surveys were designed to measure diversity and abundance of algae and invertebrates found within rocky intertidal communities on the western coast of temperate North. The rocky intertidal zone is an area between marine and terrestrial habitats where organisms living within this zone are well adapted to alternating exposures to both the air and sea.

The "undisturbed tidepools" are unique features specifically mentioned in the enabling legislation establishing Channel Islands National Park.

Physical Description of the Rocky Intertidal Zone Intertidal zones are transitional coastal regions. The cycling of the tides influences these regions. These littoral areas are located between the high and low tide marks. They can be found along rocky shores or sandy beaches. We will be taking a closer look at the rocky intertidal region.

The aim of the survey was to characterise and map baseline ecological conditions within the survey area. At the time of the survey three potential locations for bringing the export cable ashore (cable landfall) were under consideration within the intertidal survey area: one.

Such nekton is part of the rocky shore intertidal food web, since it feeds in the intertidal when the tide goes up.

Number of replicates was 3 for macroalgae and 5–8 for animals, per site.
