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...

Convergent evolution is a widespread phenomenon seen in diverse organisms inhabiting similar selective environments. However, it is unclear if similar phenotypes are produced by the same or different genes and mutations. Here we analyze the molecular mechanisms underlying convergent pigment pattern among subspecies of the beach mouse (Peromyscus polionotus) inhabiting the Gulf and Atlantic coas...

OBJECTIVE To examine the validity of beachgoers' self-reported sun protection and UV exposure using objective measures. DESIGN Eighty-eight participants completed a brief survey when they arrived at the beach; their skin was swabbed for the presence of sunscreen, while an observer recorded their clothing worn to the beach and the presence of sunburn. On leaving the beach, an exit survey detai...

The environmental indicators and the classification of beach waste are essential tools to diagnose the current situation and to indicate ways to improve the quality of this environment. The purpose of this paper was to perform a quali-quantitative analysis of the beach waste on the Curva da Jurema Beach (Espírito Santo Brazil). Three transects were used with equidistant positioning over the tot...

The purpose of this study was to measure the genetic diversity of wild beach plum and cultivated species, and to determine the species relationships using SSRs markers. An analysis of genetic diversity from ten beach plum germplasms was carried out using 11 simple sequence repeat (SSR) primers selected from 35 primers to generate distinct PCR products. From this plant material, 44 allele variat...

Studies of oil spills on sand beaches have focused traditionally on the effects of shortterm oil exposure, with recovery of sand beach macrobenthic communities occurring within several weeks to several years. The Deepwater Horizon spill resulted in chronic, multi-year re-oiling and up to 4 yr of extensive and often intensive treatments. Of the 965 km of sand beaches that were oiled, shoreline t...
