A dynamic perspective of shallow lakes of arid Patagonia as habitat for waterbirds
(Nova Science Publishers, 2010)
In arid regions, where water availability imposes significant constraints onmany species, shallow lakes and ponds have a particularly importantecological role. Meanwhile, these aquatic environments have been listedamong ...
Preface: Shallow lakes from the Central Plains of Argentina
(Springer, 2015-06)
This special issue of Hydrobiologia is devoted to the shallow lakes of the Central Plains of Argentina. The contributors were invited to submit papers dealing with different ecological topics including physical features, ...
Length-weight relationships for nine fish species from shallow lakes of the Pampa plain, Argentina
(Wiley Blackwell Publishing, Inc, 2013-06)
This study presents length-weight relationships for nine neotropical fish species collected from four shallow lakes from the southeastern Pampean region, representing the first record for these species. Also, new sizes for ...
Anabaenopsis morphospecies (Cyanobacteria, Nostocales) from Los Patos shallow lake (Province of Buenos Aires, Argentina)
(Magnolia Press, 2016-03)
The genus Anabaenopsis comprises about 20 morphospecies distributed in plankton of tropical, subtropical and temperate regions during warm periods. The morphological diversity and population dynamics of Anabaenopsis species ...
Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity
(Instituto Virtual da Biodiversidade, 2012-06)
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, ...
The trophic role of Cyphocharax voga (Hensel 1869) according to foraging area and diet analysis in turbid shallow lakes
(E Schweizerbartsche Verlags, 2013-08)
Detritivory is a widespread strategy that has been associated with shallow, warm and productive systems. Eutrophic and hypereutrophic lakes can be dominated by an assemblage of detritivorous fish species. The trophic role ...
Microbial food-web components in two hypertrophic human-impacted Pampean shallow lakes: interactive effects of environmental, hydrological, and temporal drivers
(Springer, 2019-01)
Few studies have intensively assessed the dynamic of all planktonic components and their microbial communities in hypertrophic shallow lakes. The aim of this work was to study the potential drivers shaping the microbial ...
Assessment of climate variability and land use effect on shallow lakes in temperate plains of Argentina
(Springer, 2016-04)
Areal variation in lakes is closely associated with other factors such as intensity of land use of the hydrological basins, climatology, geomorphology and depth. The main objective of this study is to assess the relationship ...
