Coastal estuaries are useful model systems to study the ecological and evolutionary responses of organisms to highly variable, discontinuous habitats. For this study, the molecular population genetic diversity of the planktonic calanoid copepod Acartia tonsa (Dana, 1849) was described based on DNA sequence variation for a 183 base-pair region of the mitochondrial 16S rRNA gene. Canadian Register of Marine Species. The distribution in this summary table is based on all the information available. Distribution of Acartia hongi sp. When several references are cited, they may give conflicting information on the status. [p.176, Fig.11, C]. Acartia discaudata and A. tonsa presented similar responses, with a decrease in EPR only at the lowest dilution of 15 psu, but showed high percentage of hatching success at all salinities tested. A postexperiment egg production method was developed to override the decline in number of copepods due to predation. In October 2005 spatial distribution of live and dead Acartia clausi and Acartia tonsa was studied in the Black and Marmara Seas and near the Marmara Sea inlet of the Bosphorus, in order to understand their fate upon transportation between two seas.

AAPB to the marine copepod Acartia tonsa was investigated in a study conducted according to ISO 14669 (1999) Water Quality - Determination of the acute lethal toxicity to marine capepods (Copepoda; Crustacea). However, it has also been claimed to be a glacial relict in northeastern North America (McAlice, 1981). Issued from : R.J. Conover in Bull.

Giesbrecht,W. : CBFO … Egg laying patterns and daily rates were evaluated as bioassay tools for measuring the nutritional value of various copepod foods as well as assessing other aspects of environmental quality. Acartia tonsa is a widespread and numerically dominant estuarine copepod containing deep mitochondrial lineages within and among populations along the northwestern Atlantic coast. Acartia tonsa is a crustaceous copepod species of zooplankton that thrives in many of the world’s estuaries, where concentrations of its prey (phytoplankton) are high. ACARTIA TONSA DANA (COPEPODA) IN YAQUINA BAY, OREGON Abstract approved Charles B. Miller In the upper estuary of Yaquina Bay, Oregon, there is an annual population explosion of Acartia tonsa, (Dana) a calanoid copepod, during the months of July, August and September, followed by a rapid decline to virtual extinction in November. We test the hypothesis that differences in salinity between the Berre Lagoon and the Gulf of Fos prevents … Acartia tonsa is a widely spread species: Indian Ocean, Malay Archipelago, Cayenne, Atlantic and Pacific coasts of the North and South Americas, Black, Azov and Mediterranean Seas (Kurashova 2002).

Acartia hudsonica is traditionally considered the winter dominant species, which is then replaced by Acartia tonsa as waters become warmer during the summer (Rice et al., 2014; Sullivan & McManus, 1986).

Abstract The calanoid copepod Acartia tonsa is the most abundant copepod species in the Berre Lagoon near Marseilles, France. The wide distribution of acartia tonsa may be a result of these copepods being transported as ballast. The effects of predation and spatial patchiness in food distribution on egg production of the marine Calanoid copepod Acartia tonsa were investigated in the laboratory.

Morphological variability of geographically distinct populations of the estuarine copepod Acartia tonsa. Acartia tonsa’s success and abundance may also be attributed to its tolerance of a wide range of ocean temperatures (-1 to 32ºC) and salinities (1 ppt to 38 ppt), helping it compete in a variety of estuarine microclimates. Bingham Oceanogr. In New England and Middle Atlantic estuaries Acartia clausi, a winter—spring copepod, and A. tonsa, a summer—fall form, alternate cycles of dominance. May 1991, Old Dominion University A Dissertation Submitted to the Faculty of Old Dominion University in Partial Fulfillment of the RESULTS We calculated geometric means of clearance rates for various ranges of average food concentrations because the distribution of clearance rates were log normal: for Acartia tonsa these ranges were 0.1 to …
