Evaluación del fitoplancton y la calidad del agua de un arroyo subtropical del Noroeste ArgentinoEvaluation of phytoplankton and water quality of a subtropical stream in the Northwest of Argentina
(Instituto de Botánica del Nordeste, 2018-11)
El arroyo Calimayo pertenece a la cuenca del río Salí, principal red fluvial de la región. Este sistema lótico fue conocido por su gran diversidad biológica. Debido a la instalación de una papelera y sus efluentes las ...
Diversity, seasonality and structure of bird assemblages associated with three wetlands in the southeastern Pampas, ArgentinaDiversidad, estacionalidad y estructura de ensambles de aves asociados a tres humedales del sudeste de la región pampeana, Argentina
(Sociedad Española de Ornitología, 2012-06)
Las lagunas de Los Padres, La Brava y Nahuel Rucá son humedales representativos de la región pampeana. Estos tres ambientes comparten ciertos aspectos limnológicos (tamaño de la cubeta, profundidad media, macrófitas ...
Ecosystem services of runoff marshes in urban lowland basins: Proposals for their management and conservationLes services écosystémiques des marais collatéraux dans les bassins urbains de plaine: propositions pour leur gestion et leur conservation
(EDP Sciences, 2017-05)
The city of La Plata, Argentina, is situated in a low alluvial zone, with streams having insufficient drainage into the Río de la Plata estuary. In April 2013, a prodigious storm front caused unprecedented flooding in the ...
Taxonomic revision of Cypridopsis silvestrii comb. nov. (Ostracoda, Crustacea) from Patagonia, Argentina with morphometric analysis of their intraspecific shape variability and Sexual dimorphism
(Magnolia Press, 2019-02)
In this study we redescribe an ostracod species belonging to the subfamily Cypridopsinae Kaufmann, 1900, sampled in seven localities of northern and southern Patagonia, Argentina. A new taxonomical combination is proposed, ...
A multiproxy approach to inferring Holocene paleobotanical changes linked to sea-level variation, paleosalinity levels, and shallow lake alternative states in Negra Lagoon, SE Uruguay
(Springer, 2010-06)
A multiproxy analysis of diatoms, chrysophyte cysts, opal phytoliths, and palynomorphs was undertaken in Negra Lagoon, to decipher Holocene changes in paleobotanical proxies associated with sea-level changes and paleolimnological ...
Dinámica del fitoplancton en tres lagos urbanos con diferentes estrategias de manejo: Análisis de floraciones estivalesPhytoplankton dynamics in three urban lakes with different management strategies: Analysis of the summer algal blooms
(Asociación Argentina de Ecología, 2019-04)
Los lagos urbanos son ecosistemas que tienden a una rápida eutrofización y que pueden desarrollar floraciones fitoplanctónicas en el período estival. En tres lagos urbanos de la Ciudad Autónoma de Buenos Aires (Regatas, ...
Comparative analysis of leaf-litter decomposition from the native Pouteria salicifolia and the exotic invasive Ligustrum lucidum in a lowland stream (Buenos Aires, Argentina)
(E Schweizerbartsche Verlags, 2013-12)
We compared loss in leaf mass and chemical changes (concentrations of carbon, nitrogen, phosphorous, acid detergent fiber, lignin and phenolic compounds) during the decay of submersed leaf-litter of the native Pouteria ...

We publish a data set of environmental and biological data collected in 2000 during the ice-free period in high mountain lakes mainly located above the local timberline in the Alps, in Italy, Switzerland and Austria. ...
Finding patches in a heterogeneous aquatic environment: pH-taxis by the dispersal stage of choanoflagellates
(John Wiley & Sons Inc, 2017-04)
Microbial eukaryotes that feed on bacteria are critical links in aquatic food webs. We used the choanoflagellate Salpingoeca rosetta, whose life history includes fast- and slow-swimming unicellular forms and multicellular ...
