      The dominant role of the river hydrology in determining the seasonality of phytoplankton in Batata Lake has been shown through studies of primary production (Roland et al., ). This role has already been recognized in other Amazonian flood-plain systems (Sioli, ), and it conforms to the flood-pulse concept of their structure. A Flora describes plants and where they live. Floras typically include a dichotomous key for identification purposes and often times will include range maps as well. Floras are almost always designed to be simultaneously regionally constrained and regionally exhaustive/complete (i.e., includes all plants that grow in that region or at least all taxonomic divisions of specified taxa).

With this book, Reavie and Smol present the first detailed description of the diatom flora of the St. Lawrence River, Canada. They provide light micrographs of diatom taxa from 35 genera, recorded in samples from the freshwater portion of the St.

Lawrence River. Therefore, considering the lack of palaeo-limnological studies concerning diatom flora from the sediment of the Brazilian aquatic environments and given, the current transformations in the global and regional environments, this study aimed to provide information about the diatom biodiversity and autoecology from a tropical : Daiane Trevisan Ruwer, Liliana Rodrigues.

Abstract: As component of an exhaustive investigation on the ecological studies of diatom communities of River Dilimiin Jos, the spatio-temporal variation of four different diatom communities was a derivative of these studies, a comprehensive compilation was made of the diatomflora of the upper mainstream channel of the river.

The floodplain of the Upper Paraná River, Brazil, is strongly influenced by hydrology, which in turn affects geomorphological and environmental conditions, and controls the form of islands in the.

diatom taxa were identified. Some of these species could be accurately determined, but 35 could not be asso¬ ciated to any described taxa in the lit¬ erature, suggesting that there is a rich unknown diatom flora in these habi¬ tats.

Recent morphometric and breeding studies of diatoms show that the present species classification is too coarse and hides significant diversity. Many species are subdivided into phenodemes, which often differ in cell size, shape, stria density and pattern, but may also have different ultrastructural features.

In the context of global environmental changes, Mediterranean rivers are considered highly endangered. Temporal and spatial increases of the dry stretches during the summer lead to the loss of river tridimensional connectivity, which represents a major threat for freshwater biodiversity.

In this study, we aimed at exploring the response of diatom communities to summer droughts by analyzing. The Río de la Plata is located on the East coast of South America and is a shallow, large-scale, turbid coastal plain estuary that covers an approximate area of 35, km e the socio-economic importance of the Río de la Plata, studies related to the biological aspects of this ecosystem are scarce, particularly in the freshwater tidal zone.

British Phycological Journal: Vol. 17, No. 2, pp. Our study showed that environmental filtering, biotic interactions, and stochastic processes were all important to community assembly processes of benthic macroinvertebrates and diatoms in the Chishui River.

Both physicochemical factors were important to the seasonal shifts of the two taxonomic. The Paraná River mainstem was sampled monthly (November –December ) in order to analyse phytoplankton structure and dynamics during a period of extreme low water discharge.

Physiognomic groups, size fractions, taxonomic groups, species and Reynolds et al. [, Journal of Plankton Research, –] functional groups were studied in relation to environmental variables. The structure and distribution of the Paraguay River phytoplankton (between 16° 03′ and 26° 53′ S and between 57° 13′ and 58° 23′ W was studied during June–July/95 and December/95–January/ Phytoplankton density values were lower in winter (mean value between and ind.

The Middle Parana River, one of the largest rivers in the world, is exceptionally rich in fauna and flora and provides researchers a glimpse into an ecosystem yet undisturbed by human civilization. Covering the key aspects of fluvial limnology and ecology related to the river, this book.

Although it is ideal to sample during high and low flows to capture all ecological changes in the river system, as part of the development of a pollution monitoring framework for the middle Paraná River, the current study was performed in late summer during a flow period with a mean-low water level ( m; Paraná city gauging station).

Introduction. The classic taxonomy of diatoms is morphology-based using features of their characteristic silica cell wall called frustule (e.g.

Krammer and Lange-Bertalot ). Medlin et al. () introduced molecular methods into diatom taxonomy. Based on molecular, morphological and cytological results, Medlin and Kaczmarska () proposed major clades of diatoms including Mediophyceae. Baker, P.D. and Fabbro, L.D.

Identification and. environmental parameters and diatom diversity. As the island is located on the boundary between Maritime and Continental Antarctica (Øvstedal and Lewis-Smith ), studying its diatom flora can add valuable information on the biogeographical boundaries of several typical Antarctic taxa.

Study area The present study has been carried out on. Horizontal salinity gradients of the surface front are weaker than those of the bottom front, and its form and location are more variable. Physical forcing in the estuary are characterized by low seasonality in the river run off (mean river discharge estimated is 24, m 3 s −1), seasonality in winds pattern (spring–summer dominated by onshore winds (NE, E, SE, and S), and fall–winter.

Ecological studies focusing exclusively on planktonic diatoms are few: Train () assessed a floristic survey of planktonic and periphytic diatoms for potential as biological indicators of ecological conditions, and Contin () also related planktonic and periphytic diatom flora to environmental indexes.

Our study showed that environmental filtering, biotic interactions, and stochastic processes were all important to community assem-bly processes of benthic macroinvertebrates and diatoms in the Chishui River.
