We surveyed 579 recreationists regarding management of the threatened, beach-dwelling Hooded Plover Thinornis rubricollis. We postulated that: (1) lower awareness of the species and higher 'inconvenience' of management would engender less favourable perceptions of conservation and management; and (2) that frequency of beach use and dog ownership may mediate perceptions and levels of awareness a...

The beach hopper amphipod Talorchestia quoyana is not distributed homogeneously in its sandy beach habitat, but instead occurs in dense patches under large pieces of tidal debris. This marked patchiness on a scale of just a few metres may create a higher level of aggregation among hosts for the symbionts and parasites of beach hoppers. Prevalence of infection by a mermithid nematode parasite va...

We investigated the effectiveness of Escherichia coli community fingerprinting for identifying fecal pollution sources impacting a recreational beach. E. coli in water collected from the beach, nearby creek and storm sewer outfall were enumerated using membrane filtration, while E. coli communities were characterized following polymerase chain reaction analysis and denaturing gradient gel elect...

Printed on recycled paper The overall mission of this work is to provide science-based information and methods that will allow beach managers to more accurately make beach closure and advisory decisions, understand the sources and physical processes affecting beach contaminants, and understand how science-based information can be used to mitigate and restore beaches and protect the public. The ...

In this paper, a conceptual model for synchronous applications in ubiquitous computing environments is proposed. To test its applicability, it was used to structure the architecture of the BEACH software framework that is the basis for the software infrastructure of i-LAND (the ubiquitous computing environment at FhG-IPSI). The BEACH framework provides the functionality for synchronous cooperat...

Sand contamination due to parasites was evaluated on the beaches of Porto de Galinhas, Muro Alto and Maracaípe in southern Pernambuco State. Samples were analyzed using the spontaneous sedimentation and modified Rugai methods. The highest contamination occurred on Porto de Galinhas beach, from which 42% of the samples were contaminated with Ancylostoma larvae and 13% with Trichuris sp. eggs. Fr...

Beach recreation values are often needed by policy-makers and resource managers to efficiently manage coastal resources, especially in popular coastal areas like Southern California. This article presents welfare values derived from random utility maximization-based recreation demand models that explain an individual’s decisions about whether or not to visit a beach and which beach to visit. Th...

As the main part in terrestrial ecosystems, vegetation is the result of long-term effect by variety natural factors of a region. In the same climatic regions, the heterogeneity of natural conditions is small and the vegetation also has certain homogeneity. These provide us a appropriate selection to analyze the vegetation change according to unique phonological characteristics of different regi...
