This study examines whether plankton of the Lagoon of Venice could be considered as a bio-indicator of areas subjected to various anthropogenic influences. This study was a two year hydrochemical and biological survey in five areas of the Lagoon of Venice, each with different environmental conditions due to pollution from urban, industrial, thermal and agricultural wastes. Phytoplankton associa...

Retrievals of inherent optical properties (IOPs) and chlorophyll-a concentration (Chla) were investigated for AVNIR-2 images with 30 m spatial resolution and four bands in the southwest tropical lagoon of New Caledonia. We corrected the atmospheric and sea-surface reflectance iteratively through the retrieval of IOPs. After an additional correction of seafloor reflectance, the estimated IOPs an...

In this chapter we define coastal lagoons according the definition proposed by Kjerfve (1994) as “shallow water bodies separated from the ocean by a barrier, connected at least intermittently to the ocean by one or more restricted inlets, and usually oriented shoreparallel”. This definition is given in an introduction chapter of a multiauthor book edited by Kjerfve (1994). Nevertheless, in the ...

The VAHINE mesocosm experiment, conducted in the low-nutrient low-chlorophyll waters of the Noumea lagoon (coastal New Caledonia) was designed to trace the incorporation of nitrogen (N) fixed by diazotrophs into the food web, using large volume (50 m) mesocosms. This experiment provided a unique opportunity to study the succession of different N2-fixing microorganisms (diazotrophs) and calculat...

An understanding of the nature of wastes in an anaerobic swine lagoon is essential in the design and operation of alternative collection, treatment, and disposal facilities for environmental quality management such as odor control, nutrient and pathogen reduction. In this study, the characterization of an anaerobic swine waste treatment lagoon (0.40 ha) from a farrowing operation (~2000 sows) w...

Population structure, growth, length-weight relationship and reproduction characteristics of leaping grey mullet (Liza saliens (Risso, 1810) were investigated in Beymelek Lagoon from February 2006 to January 2007.  During the study, a total of 1248 leaping grey mullet were captured by gill- and trammel nets of various mesh sizes. Male to female ratio for leaping grey mullet population in Beymel...

We studied the seawater carbon dioxide (CO2) system in the Palau coral reef by measuring total alkalinity (TA) and total dissolved inorganic carbon (DIC). Variation in the CO2 system on the reef flat and in the lagoon was analyzed by TA–DIC diagrams, taking into accounts the differing residence times of seawater. CO2 in the offshore water was relatively stable in space and time, but on the reef...

Abstract Cladocera represent an important zooplankton group because of their seasonal prominence in terms abundance and contribution controlling primary production (phytoplankton). On a global scale, there are few studies on hypersaline environments. The present work aims to evaluate the spatio-temporal variation assemblage across salinity gradient habitats Araruama Lagoon. Samples were collect...

Lomentaria hakodatensis Yendo, known from China, Japan, Korea, and the Pacific coasts of North America, was recorded for the first time in the lagoon of Venice on the Adriatic Sea in 2000. Specimens in the reproductive stage had tetrasporophytes, male, and female gametophytes. Morphological, anatomical, and reproductive features of the thalli are described and the occurrence of the species in t...

The chromosomes of the Mediterranean killifish, Aphanius fasciatus from two populations, the Lagoon of Venice (LV, 15 specimens) and the Lagoon "Stagnone di Marsala" (Sicily) (SM, 48 specimens), have been investigated using conventional Ag-staining and fluorescent in situ hybridization (FISH) with 18S rDNA probe. The two methods revealed variation in the number of major rDNA sites ranging from ...
