Salinity and tide heights recorded for a month at P(0), a point in the northern section of the Venetian lagoon, are the basic experimental data used to construct a numerical model which describes the salinity variations at P(0) as a function of the tides measured at the Lido entrance. The time variation of the salinity pattern iss interpreted in terms of a lagoon system in which a freshwater so...

We investigated seasonal differences in community structure and activity (leucine incorporation) of the planktonic bacterial assemblage in the freshwater and brackish-water zones of a shallow coastal lagoon of the southwestern Atlantic Ocean. Alphaproteobacteria formed the dominant microbial group in both zones throughout the sampling period. After an intrusion of marine water, members of the S...

Introduction: Obesity is a growing public health problem in our population, patients affected with this condition are increasing and also the rate in the younger population. There are several alternatives for surgery or bariatric surgery with variations in their results and possible complications. Materials and Methods: 900 patients have undergone laparoscopic gastric plication (LGP), a laparos...

Sediment photosynthetic production and community respiration were investigated for 1 yr in the south-west lagoon of New Caledonia (surface area: 2000 km'; mean depth: 21 m). Metabolic fluxes were measuredbat the water-sediment interface using benthic enclosures, at 60 sampling stations randomly distributed in space and time. Mean gross primary production (Pg) was 12.06 mol C m-' yr-l. Mean resp...

Bathing in the Blue Lagoon, a specific geothermal biotope in Iceland has been known for many years to be beneficial for human skin in general and for patients with psoriasis and atopic dermatitis in particular. The scientific rationale for this empirical observation, however has remained elusive. We now report that extracts prepared from silica mud and two different microalgae species derived f...

Molecular techniques were used to compare the compositions of the bacterial communities of the 2 following lagoons from the former soda Texcoco Lake, Mexico: the restored Facultativa lagoon and the Nabor Carrillo lagoon. Ribosomal intergenic spacer analysis (RISA) revealed that bacterial communities of the 2 lagoons were different and presented a relatively low diversity. Clone libraries of 16S...

An efficient class of nonlinear models, constructed using cardinal B-spline (CBS) basis functions, are proposed for high tide forecasts at the Venice lagoon. Accurate short term predictions of high tides in the lagoon can easily be calculated using the proposed CBS models.

To some naturalists, Mastigias medusae in marine lakes, Palau, symbolize the evolutionary process (Faulkner, 1974). In the first scientific publication on marine lake Mastigias, Hamner & Hauri (1981) suggested that different long-distance horizontal migrations and different morphologies among populations isolated in three different lakes ‘might be considered of specific or subspecific importanc...

In Mar Chiquita coastal lagoon (Argentina), the reefs of the invasive polychaete Ficopomatus enigmaticus (Serpulidae) serve as concentration areas for invertebrates and vertebrates and as potential foci of parasite transmission (mainly digeneans). To analyse the role of F. enigmaticus as facilitator of parasite transmission, and to evaluate the influence of the habitats selected by 2 species of...
