Microbiological monitoring of bivalve mollusc production areas by national or regional authorities is usually undertaken as part of a programme to classify the areas according to the perceived risk of the presence of pathogenic microorganisms based on the concentrations of faecal indicator bacteria present in the area. The indicator bacteria used are generally of the coliform group: total colif...

presenting additional information, views, and analyses that may help to refine the HHRA to be more reflective of the potential for exposures and risks due to polychlorinated biphenyls (PCBs) in the Rest of River portion of the Housatonic River and its floodplain. These comments generally follow the structure of the Peer Review Charge developed by EPA. As such, they first discuss each of the thr...

Human exploitation of fi sh and other aquatic animals such as crustaceans and mammals is virtually ubiquitous on Earth and since ancient times has provided humanity with food, income and other social goods such as recreation. Fishing where the primary objective is not to produce food or generate income through the sale or trade of fi shing products is commonly termed ‘recreational fi shing’ or ...

If you build it, will they come?" (2016). USDA Forest Service / UNL Faculty Publications. 301. a b s t r a c t a r t i c l e i n f o National forests have a wealth of natural amenities that attract over 175 million recreational visitors a year. Although natural amenities draw visitors to national forests, many of the recreational activities that they engage in require built amenities, such as r...

Increasing recreational use of national parks and protected areas can impact natural and cultural resources and the quality of the visitor experience. Determining how much recreational use can ultimately be accommodated in a park or protected area is often addressed through the concept of carrying capacity. Contemporary approaches to carrying capacity – including the Visitor Experience and Reso...

Enterolert (IDEXX Laboratories Inc., Westbrook, Maine), a semiautomated, most probable number method for enumeration of enterococci, was compared with the standard membrane filter method by parallel testing of 138 marine and freshwater recreational bathing water samples. No statistically significant difference and a strong linear correlation were found between methods. Culturing of 501 Enterole...

Fishing constitutes one of the most significant threats to marine biodiversity and ecosystem function, documented by a growing body of information on the numerous impacts to populations, community structure, and habitats (Dayton et al., 1995; Roberts, 1995; Jennings and Polunin, 1996). Besides the more obvious effects on species population structure, fishing activities may also reduce the struc...
