dynamics of the parasite marteilia refringens (paramyxea) in mytilus galloprovincialis and zooplankton populations in alfacs bay (catalonia, spain). | since the first description of marteilia refringens (paramyxea) in flat oysters ostrea edulis in 1968 in the aber wrach, brittany (france), the life-cycle of this parasite has remained unknown. however, recent studies, conducted in the 'claire' system, have proposed the planktonic copepod acartia grani as a potential intermediate host for the parasite. nevertheless, experimental transmission of the parasite through the copepod has failed. recent studies in this field have reported the presence o ... | 2007 | 17623489 |
identity and systematic position of paradinium poucheti and other paradinium-like parasites of marine copepods based on morphology and nuclear-encoded ssu rdna. | paradinium and paradinium-like parasites were detected in various copepod hosts collected in the nw mediterranean sea, the north atlantic ocean, and the godthåbsfjord (greenland). the identity and systematic position of the parasitic, plasmodial protist paradinium was investigated on the basis of ssu rdna and morphology. ssu rdna sequences were obtained from 3 specimens of paradinium poucheti isolated from their cyclopoid copepod host, oithona similis. in addition, a comparable sequence was obta ... | 2008 | 18485817 |
what factors drive copepod community distribution in the gulf of gabes, eastern mediterranean sea? | the spatial and temporal variations in copepod communities were investigated during four oceanographic cruises conducted between july 2005 and march 2007 aboard the r/v hannibal. a close relationship was observed between the temperature, salinity, hydrographic properties and water masses characterising the gulf of gabes. indeed, water thermal stratification began in may-june, and a thermocline was established at a 20-m depth, but ranged from 25 m in july to more than 30 m in september. the zoopl ... | 2014 | 24170503 |
response of marine copepods to a changing tropical environment: winners, losers and implications. | background. climate change concurrent with anthropogenic disturbances can initiate serial changes that reverberate up the food chain with repercussions for fisheries. to date, there is no information available concerning the combined effects of global warming and human impacts on tropical marine food webs. while temperate copepods respond differently to warming and environmental stressors, the extent to which tropical copepods can adapt to rising temperature of already warm waters remains unknow ... | 2016 | 27257540 |
quantifying preferences and responsiveness of marine zooplankton to changing environmental conditions using microfluidics. | global environmental change significantly affects marine species composition. however, analyzing the impact of these changes on marine zooplankton communities was so far mostly limited to assessing lethal doses through mortality assays and hence did not allow a direct assessment of the preferred conditions, or preferendum. here, we use a microfluidic device to characterize individual behavior of actively swimming zooplankton, and to quantitatively determine their ecological preferendum. for the ... | 2015 | 26517120 |
monitoring of genotoxicity in marine zooplankton induced by toxic metals in ennore estuary, southeast coast of india. | the present study provides preliminary in-situ data on genetic integrity of marine zooplankton. paracalanus parvus, oithona rigida and euterpina acutifrons were collected during four different seasons (summer, pre-monsoon, monsoon and post-monsoon) from 2011 to 2012 in ennore and kovalum estuaries. dna damage levels in different zooplankton were analyzed by comet assay and were correlated with different environmental stressors. spatial and temporal variations in dna damage was observed in all th ... | 2014 | 25287225 |
restoration impact of an uncontrolled phosphogypsum dump site on the seasonal distribution of abiotic variables, phytoplankton and zooplankton along the near shore of the south-western mediterranean coast. | 'in connection with the taparura project, we studied the distribution of phytoplankton and zooplankton communities in relation to environmental variables at 18 stations sampled during four coastal cruises conducted between october 2009 and july 2010 on the north coast of sfax (tunisia, western mediterranean sea). the inshore location was largely dominated by diatoms (66 %) represented essentially by members of the genera navicula, grammatophora, and licmophora. dinophyceae were numerically the s ... | 2013 | 23149925 |
spatial distribution of copepods along the salinity gradient of perai river estuary, penang, malaysia. | investigation on copepod communities in perai river estuary was conducted from november 2005 to may 2006. five stations were established for monthly sampling and were located from the river mouth to the upper reaches of the river. copepod samples were collected from vertical tows using a standard zooplankton net. the perai river estuary was slightly stratified and salinity decreases significantly from the mouth of the river towards the upper reaches of the river. a total of 28 species of copepod ... | 2012 | 24218935 |
changes in the abundance and composition of zooplankton from the ports of mumbai, india. | zooplankton abundance, biomass, and composition from the ports of mumbai, india, were studied by selecting 14 stations in and around the area during three different periods between 2001 and 2002 (nov 01, apr 02, and oct 02). the results are compared with the records available since the 1940s. copepod species such as canthocalanus sp., paracalanus arabiensis, cosmocalanus sp., euterpina acutifrons, nannocalanus minor, and tortanus sp. which were not reported in the earlier studies were observed d ... | 2010 | 19649716 |
[thermal tolerance of some marine copepods]. | by using experimental ecological methods, the 24 hours semi-lethal temperature (24 h lt50) of typical copepods living in the coastal area of east china sea was determined to elucidate the effects of thermal discharge from power station on the coastal ecosystem. the results indicated that different copepods at same natural acclimated temperature and specific copepod at different initial acclimated temperature had different thermal tolerance capability. the 24h lt50 of calanus sinicus and sinocala ... | 2008 | 18464656 |
discriminating zooplankton assemblages in neritic and oceanic waters: a case for the northeast coast of india, bay of bengal. | zooplankton species distribution and abundance data at 17 locations in the inshore (10-30 m), shelf (50-200 m) and oceanic (2,500-2,800 m) regions off northeast india (bay of bengal) during january 1999-april 2001 revealed 112 taxa represented by 30 divergent groups. copepods (58 species) dominated (87%) the population numerically. in general zooplankton diversity (margalef richness d, shannon-wiener h', pielou's evenness j') increased in the direction of the open sea relative to coastal locatio ... | 2006 | 16125769 |
