A detailed look at the ecology of a disease can lead to recommendations for public health interventions that are not otherwise obvious. To illustrate this point, this paper discusses the ecology and control of infection with the Australian arbovirus Ross River virus (RRV). The traditional insecticidal approach to mosquito control is recommended when an outbreak of RRV results from the expansion...

Ground based in-situ measurements of carbon dioxide (CO2) and methane (CH4) at the dry lakebed at Railroad Valley (RRV) playa, Nevada, USA (38°30.234′ N, 115°41.604′ W, elevation 1437 m) were conducted over a five day period from 20–25 June 2010. The playa is a flat, desert site with virtually no vegetation, an overall size of 15 km × 15 km and is approximately 110 km south-west of the nearest ...

The spatial and temporal variations of Ross River virus infections reported in Queensland, Australia, between 1985 and 1996 were studied by using the Geographic Information System. The notified cases of Ross River virus infection came from 489 localities between 1985 and 1988, 805 between 1989 and 1992, and 1,157 between 1993 and 1996 (chi2(df = 2) = 680.9; P < 0.001). There was a marked increa...

The interclick intervals of captive dolphins are known to be longer than the two-way transit time between the dolphin and a target. In the present study, the interclick intervals of free-ranging baiji, finless porpoises, and bottlenose dolphins in the wild and in captivity were compared. The click intervals in open waters ranged up to 100-200 ms, whereas the click intervals in captivity were in...

The following information is missing from the Funding section: This paper is part of the PhD thesis project of S. Romero-Cordoba, a student of the Biomedical Sciences PhD Program of the Autonomous National University of Mexico. The complete, correct Funding statement is: This work was funded by the National Institute of Genomic Medicine (INMEGEN/CI/019/2009). S. Romero-Cordoba, RRV, and RAL rec...

Ross River virus (RRV), Barmah Forest virus (BFV), and dengue are three common mosquito-borne diseases in Australia that display notable seasonal patterns. Although all three diseases have been modeled on localized scales, no previous study has used harmonic models to compare seasonality of mosquito-borne diseases on a continent-wide scale. We fit Poisson harmonic regression models to surveilla...

A tetravalent rhesus-human reassortant rotavirus (RRV-TV) vaccine (4 x 10(4) plaque-forming units/dose) was evaluated for safety, immunogenicity and efficacy in a prospective, randomized, double-blind, placebo-controlled trial involving 540 Brazilian infants. Doses of vaccine or placebo were given at ages 1, 3 and 5 months. No significant differences were noted in the occurrence of diarrhoea or...

Understanding the spatial and temporal variation of nutrient concentrations, loads, and their distribution from upstream tributaries is important for the management of large lakes and reservoirs. The Three Gorges Dam was built on the Yangtze River in China, the world's third longest river, and impounded the famous Three Gorges Reservoir (TGR). In this study, we analyzed total nitrogen (TN) conc...

River Ganga is a lifeline to about 500 million people inhabiting its basin. The river Ganga provides water for drinking, domestic needs, agriculture, livelihoods, industrial use, fishing, boating, recreation, religious, cultural activities and for energy. Besides the humans, the river supports rich fauna and flora, including the endangered Ganges river dolphin (Platanista gangetica gangetica), ...

The National Marine Fisheries Service's Alaska Fisheries Science Center uses the NOAA Technical Memorandum series to issue informal scientific and technical publications when complete formal review and editorial processing are not appropriate or feasible. Documents within this series reflect sound professional work and may be referenced in the formal scientific and technical literature. In the ...
