Wet-dry tropical estuaries are extreme environments driven by wet season rainfall and runoff events. The biota associated with these systems highly adapted to large fluctuations in salinity. There few examples globally where water extraction for human needs has not yet had a major impact on freshwater flow volumes seasonal variability systems. Therefore, this study examined the importance of se...

The course of environmental conditions and shelf macrobenthic communities off Central Chile ( 361S) during the strong 1997–98 El Niño (EN) event is compared with a subsequent and basically ‘‘normal’’ period (2002–2003). Changes in macrofaunal community, feeding mode structure, and biomass size spectra are contrasted over time with changes in oceanographic and sediment settings, in order to asse...

Hydrothermal fluids passing through sediments create a habitat hypothesized to influence the community structure of infaunal macrobenthos. Here we characterize the density, biomass, species composition, diversity, distributions, lifestyle, and nutritional sources of macroinfauna in hydrothermal sediments in NE and SW Pacific settings, and draw comparisons in search of faunal attributes characte...

guilan province is located in south and south-west of the caspian sea. guilan is one of the richest and the most humid region in the country due to suitable climate, ample rainfall and many water sources (springs, rivers, creeks,..),. despite the prevailing favorable conditions, limnological studies, especially in the mountainous regions of this province are limited. a limnological study was co...
