Contribution to our knowledge of the South African intertidal zone
The two papers presented herewith as a thesis for the degree of PhD are two items from a series which is being issued from the Zoological Department of the University of Cape Town. In a sense each paper is complete in itself; but as the papers are also parts of a larger whole, it is necessary to …

A finite element model of submarine ground water discharge to tidal estuarine waters
… to simulate ground water discharge to the intertidal zone of estuarine systems. This research may be the first attempt to model the ground water discharge process in a tidal estaurine system. The development of FEM Coast was undertaken as no existing ground model was capable of directly …

Piping plover habitat suitability on central Long Island, New York barrier islands
… brood-rearing than other ocean beach habitats (intertidal zone, intertidal zone wrack, berm, berm wrack, and open vegetation). Broods with access to ephemeral pools spent more time in them, and when in them had greater foraging rates and were exposed to greater arthropod abundances than in other …

Salinity tolerance and osmoregulation in several subtropical decapods
… of U. vocans, which occurs lowest in the intertidal zone, died within 24 hours of exposure. All U. urvillei died within two days of exposure. Uca annulipes, which lives in the highest region of the intertidal zone, was the most tolerant to rapid freshwater exposure, with 70% of crabs …

Subtidal concrete piling fauna in Monterey Harbor, California
… of a concrete piling from the bottom to the low intertidal zone beneath Municipal Wharf No. 2 in Monterey Harbor, California. Sampling was performed at 0.5 m(2) surface area increments. Wet biomass measurements were taken, the organisms were identified and an evaluation of species abundance in …

Changing Tides: sculpting heterogeneity through exposing and submerging form in tidal pool design
… systems and ecological interactions of the intertidal landscape. The tidal pool sits at this intersection of land and water, known as the intertidal zone. They are site specific social spaces where people can interact with marine life and they are valuable public places that can connect …

Aspects of ecology and algal physiology in Hawaii's rocky intertidal zones
Intertidal zones are vulnerable to anthropogenic impacts that result from human populations concentrated near coastal waters and while the impact on temperate rocky intertidal systems is much studied, comparatively less is known about these habitats in the tropics. To bolster knowledge and …

Wave Induced Vertical Pore Pressure Gradients at Sandy Beaches
… These challenges are further exacerbated in the intertidal zone where the addition of infiltration-exfiltration, wave run-up and run-down, bore collapse, cyclic emergence and submergence of sediments, interactions between standing waves and incident bores, and other processes must be considered. …

Nesting and Brood Rearing Ecology of the Vancouver Canada Goose on Admiralty Island Southeast of Alaska
… while creches were more common in meadows and intertidal zones. Breeding adults and goslings were comparatively less vocal in the forest. Goslings less than 2 weeks of age used forest habitat extensively and shifted to forest edge and intertidal zones with age. Forest habitats, rather than open …

Marine Interstitial Tardigrades and Other Meiofauna of Huntington Beach, South Carolina.
… abiotic variables.</p><p>Cores were taken in the intertidal zone along three elevations. Each core was divided into depth samples and was processed to remove meiofauna. Each taxon (>1500 specimens) and tardigrades was statistically analyzed using three-way ANOVA to compare distribution …

Behavioural and isotope ecology of marine-foraging chacma baboons (Papio ursinus) on the Cape Peninsula, South Africa
… its diet with protein-rich foods from the marine intertidal zone. There are qualitative descriptions of this behaviour in the literature, but the relative contribution of marine foods to baboon diet, the influence of lunar cycles on exploitation and the impacts of marine foraging on ranging …

Influence of beach hydrodynamics on saltwater transport and oil persistence in beaches
… and freshwater does not play a role in the intertidal zone of beaches. This hypothesis is tested through numerical modeling and laboratory experiments and is rejected. The results show that the density gradient has significant effect on solute transport in the intertidal zone. Another …

Distribution and predictors of non-indigenous marine species within South Africa's MPA network
… of the 23 South African MPAs were surveyed intertidally for alien and invasive species. The intertidal zone was divided into high-, mid- and low-shore and surveys were conducted during spring low tide. The presence and location in the intertidal zone of alien and invasive species were …

Explorations of morphological change at Cape Henlopen, DE using remote sensing, rapid-response GPS-equipped vehicles and numerical modeling
… data covering the Cape's offshore bathymetry, intertidal zone, beach face and dune fields. Current meters and pressure sensors were deployed for several tidal cycles, on a small intertidal bathymetric feature on the bayside and a stretch of the oceanside of the Cape to study the currents in the …

Is The Exotic Brazilian Pepper, Schinus Terebinthifolius, A Threat To Mangrove Ecosystems In Florida?
… terebinthifolius was found growing in the intertidal zone of Mosquito Lagoon alongside three native species of mangroves, Rhizophora mangle, Avicennia germinans and Laguncularia racemosa. The purpose of my study was to evaluate competition between the invasive S. terebinthifolius and these …

Variations in shell form in the gastropod genus Diodora
… foramen and a greater number of ribs than intertidal specimens. Specimens from higher latitudes have a less constricted foramen and an increased number of ribs. In the subtidal sample, larger specimens characterize higher latitudes. Analysis performed on all specimens of D. cayenensis, …

Sediment Provenance of Tsunami Deposits: Implications for Assessing the Relative Intensity of Paleotsunamis from the Sendai Coastline of Japan
… tsunami sediments are similar to that of the intertidal zone, indicating that the dominant sediment source was from locations within 300 m of the coastline. PAM (partitioning around medoids) cluster analysis further provided evidence of a coastal to nearshore sediment source as it clustered …
