The box jellyfish Alatina moseri forms monthly aggregations at Waikiki Beach 8-12 days after each full moon, posing a recurrent hazard to swimmers due to painful stings. We present an analysis of long-term (14 years: Jan 1998- Dec 2011) changes in box jellyfish abundance at Waikiki Beach. We tested the relationship of beach counts to climate and biogeochemical variables over time in the North P...
Seafood constitutes an important food component and a cheap source of protein in developing countries. Shrimps are prone to bacterial contamination in their environment and have been frequently implicated in Vibrio parahaemolyticus infection. Of the 121 Penaeus monodon collected from coastal beaches in Douala, 79(65.3%) were contaminated with Vibrio spp. Presumed Vibrio sp. were identified by s...
AIM Ischemic brain damage related to the beach chair position is a matter of concern. The current study was designed to evaluate whether the beach chair position before and during general anesthesia differentially induces changes in cerebral oxygenation as determined by near-infrared spectroscopy (NIRS) in surgical patients. METHODS We evaluated brain tissue oxygen index (TOI) values using th...
Studies evaluating the relationship between microbes and human health at non-point source beaches are necessary for establishing criteria which would protect public health while minimizing economic burdens. The objective of this study was to evaluate water quality and daily cumulative health effects (gastrointestinal, skin, and respiratory illnesses) for bathers at a non-point source subtropica...
Sea-level rise induced by climate change may have significant impacts on the ecosystem functions and ecosystem services provided by intertidal sediment ecosystems. Accelerated sea-level rise is expected to lead to steeper beach slopes, coarser particle sizes and increased wave exposure, with consequent impacts on intertidal ecosystems. We examined the relationships between abundance, biomass, a...
DAI, Z.-J.; CHEN, J.-Y.; DU, J.-Z., and LI, C.-C., 2008. Seasonal changes of sandbar behavior in Nanwan Beach, South China. Journal of Coastal Research, 24(5), 1209–1216. West Palm Beach (Florida), ISSN 0749-0208. Frequent leveling data of beach profiles is collected from Nanwan Beach, which is characterized by a large seasonal variation in wave climate. Variability of the bar crest position ob...
A major goal in evolutionary biology is to understand how and why populations differentiate, both genetically and phenotypically, as they invade a novel habitat. A classical example of adaptation is the pale colour of beach mice, relative to their dark mainland ancestors, which colonized the isolated sandy dunes and barrier islands on Florida's Gulf Coast. However, much less is known about diff...
Clams, Donax variabilis, responded to sound stimuli presented to them in a laboratory aquarium by jumping out of the sand, lying on the sand for several seconds, and digging in again. On a beach, clams jump out of the sand and ride waves, migrating shoreward with the rising tide and seaward with the falling tide. Parallels between clam behavior on a beach and that elicited in the laboratory sug...
ALVAREZ-ELLACURIA, A.; ORFILA, A.; OLABARRIETA, M.; MEDINA, R.; VIZOSO, G., and TINTORÉ, J., 2010. A nearshore wave and current operational forecasting system. Journal of Coastal Research, 26(3), 503–509. West Palm Beach (Florida), ISSN 0749-0208. An operational forecasting system for nearshore waves and wave-induced currents is presented. The forecasting system (FS) has been built to provide r...
Recent research has shown the developments made in the analysis of gross movement patterns in tennis, but such research has yet to be extended to the field of beach volleyball. This study was designed to develop a method for analysing gross movement patterns so as to quantify movement types and their relationship to real competition and performed during the European Beach Volleyball Championshi...
