Giardia and Cryptosporidium are the most frequent enteric protozoa causing gastroenteritis in humans worldwide. Intense recreational activity at Portuguese river beaches triggered the opportunity for a 2-year seasonal survey of 19 large river basin beaches. A total of 74 samples were collected and processed according to USEPA Method 1623 to detect Cryptosporidium and Giardia (oo)cysts. Faecal i...

Unlike the advances generated on land, the knowledge of global diversity patterns in marine ecosystems is limited to a small number of studies. For sandy beaches, which dominate the world's ocean shores, previous meta-analyses highlighted the role of beach morphodynamics in explaining species richness patterns. Oceanographic variables and historical processes have not been considered, even thou...

Beach surface has considerably increased since 1956 by the construction of breakwaters and ports, but some beaches are still prone to erosion. An adequate management of the, nowadays fragile, underwater prairies and dune vegeta...

Sandy coastal and inland beaches provide important habitat for shorebirds during the breeding, migration, and over-wintering seasons (Brown et al. 2000). These same beaches often are attractive to humans for recreation (Maguire et al. 2011), residential or commercial activity (Brown et al. 2010) and, in many areas, human use is intensive (De Ruyck et al. 1997). Human use of beaches can result i...

Though species interactions across local environmental gradients are well studied, the way in which species interactions shift between different habitats on a landscape scale has received less attention. We hypothesised that interactions among a suite of shoreline plant species shift across a hydrodynamic-exposure gradient, leading to generation of apparently distinct habitat types (e.g. bare c...

BACKGROUND Nest selection is widely regarded as a key process determining the fitness of individuals and viability of animal populations. For marine turtles that nest on beaches, this is particularly pivotal as the nesting environment can significantly control reproductive success.The aim of this study was to identify the environmental attributes of beaches (i.e., morphology, vegetation, urbani...

EPA Method 1600 and Enterolert are used interchangeably to measure Enterococcus for fecal contamination of public beaches, but the methods occasionally produce different results. Here we assess whether these differences are attributable to the selectivity for certain species within the Enterococcus group. Both methods were used to obtain 1279 isolates from 17 environmental samples, including in...

Going to beaches is a popular pastime for many people in Karachi. Lifeguards have been deployed on many beaches for the safety and protection of beachgoers. This cross-sectional survey was conducted to study the opinions and experiences of lifeguards posted at eight beaches of Karachi. Ignorance among beachgoers about how dangerous it could be at seaside, was reported by 19 (61.3%) out of 31 li...

Although urban wet weather discharges may have elevated concentrations of fecal indicator bacteria impacting water quality at swimming beaches, not all of these bacteria may arise from human sources. In this study, the contribution of non-human fecal indicator bacteria was quantified by sampling coastal reference beaches in southern California. Samples were collected at beaches near stormwater ...
