The genus Pseudo- nitzschia (Bacillariophyceae) in continental shelf waters of Argentina (Southwestern Atlantic Ocean, 38–55°S)
The distribution pattern of Pseudo- nitzschia species, associated phytoplankton flora and its relationships with main environmental factors were studied for the first time in continental shelf surface waters of the Argentine Sea (Southwestern Atlantic Ocean, 38–55°S).

| description | The distribution pattern of
Pseudo-
nitzschia species, associated phytoplankton flora and its relationships with main environmental factors were studied for the first time in continental shelf surface waters of the Argentine Sea (Southwestern Atlantic Ocean, 38–55°S). Both qualitative and quantitative samples, collected during summer and fall 2003, were examined using light and scanning electron microscopy. Results indicated that the genus
Pseudo-
nitzschia has a wide distribution along the studied area. It was present at low densities, with infrequent peak abundances and appeared most frequently as a minor component of the diatom populations that typically develop on the continental shelf of the Argentine Sea. Moreover, phytoplankton communities were numerically dominated by unidentified phytoflagellates (≤5
μm) throughout almost all samples analyzed. Eight
Pseudo-
nitzschia species were identified in our study:
P. australis,
P. fraudulenta,
P. heimii,
P. lineola,
P. pungens,
P. cf.
subcurvata,
P. turgidula and
P. turgiduloides. Of these,
P. heimii,
P. lineola and
P. turgiduloides are new records for the Argentine Sea. Their presence in the area is attributable to the influence of southerly cold water masses. Spatial and temporal variations of the environmental parameters recorded in the study area generally determined the distribution of
Pseudo-
nitzschia species.
P. pungens and
P. australis were widely distributed and reached high densities, especially in waters with elevated temperatures and salinities (around 15
°C, 33.8
psu) and low nutrients concentrations. On the other hand,
P. heimii,
P. lineola,
P. turgidula and
P. turgiduloides showed a more restricted distribution, with lower densities in relatively cold, less saline (8
°C, 32.45
psu) and nutrient-rich waters. From the
Pseudo-
nitzschia species found throughout this survey,
P. australis,
P. fraudulenta,
P. pungens and
P. turgidula are known as domoic acid (DA) producers around the world, but there is little information on the potential toxicity of these species in Argentina. |
