Benthic Invertebrates of the Lower West River
The purpose of this study was to document existing benthic organisms of the lower West River in New Haven and West Haven, Connecticut, in order to enable monitoring of salt marsh restoration. Seventeen sites were sampled between the Chapel Street Bridge and the mouth of the West River during the month of July 1995. All sites contained polychaete worms and other organisms typical of estuarine sy...
متن کاملGrowth and reproductive biology of Capoeta damascina (Valenciennes, 1842) from a tributary of Tigris
Growth and reproductive attributes were determined for Capoeta damascina, an endemic fish species from west of Iran. A total of 147 specimens of both sexes were sampled monthly from November 2008 to October 2009. The overall sex ratio was female biased. Males were aged 0-4 years and females 0-5 years. The von Bertalanffy growth parameters were estimated as Linf=34.81 cm, k=0.27 year-1, t0=-0.65...

متن کاملGlobal biodiversity patterns of benthic marine algae.
Species richness patterns are remarkably similar across many marine taxa, yet explanations of how such patterns are generated and maintained are conflicting. I use published occurrence data to identify previously masked latitudinal and longitudinal diversity gradients for all genera of benthic marine macroalgae and for species in the Order Bryopsidales. I also quantify the size, location, and o...
متن کاملSeasonal variation in physico-chemical properties and zooplankton biomass in Greater Zab River -Iraq
صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...
