“…Boeckella fluvialis has the facultative ability to live in the edge habitat of lotic waters where it is more successful than most of its Australian congeners. The species has a counterpart in South America in the form of B. bergi which is considered by Previattelli et al (2015) to be the only Boeckella on that continent that is well adapted to running waters. Boeckella triarticulata, which is ubiquitous in Australian lentic waters (Bayly 1964;Timms 1970), was also found to be relatively widely distributed in this study, indicating its strong dispersal ability.…”

Freshwater calanoid copepods develop abundant populations in lentic water bodies such as lakes, reservoirs and lagoons. In this study, we examined the potential habitat value of edges in lotic systems such as creeks and rivers where waters tend to stagnate, providing lentic‐like environments. We examined a total of 353 edge samples collected from 321 sites across the state of New South Wales, Australia, with latitudes in the range 28.3–37.4°S and elevations in the range 2–1834 m above sea level. Of the total samples examined, calanoid copepods were found in 94 samples, with the frequency of occurrences of species decreasing in the order: Boeckella fluvialis Henry, B. triarticulata (Thomson), Gladioferens spinosus Henry, G. pectinatus (Brady), B. major Searle, B. minuta Sars, and Calamoecia lucasi Brady. The probability of occurrence of the calanoid copepods was related negatively to both latitude (as absolute values) and elevation, based on logistic regression models. We conclude that the edges of many lotic systems provide additional habitats for some species of freshwater calanoid copepods, with constraints on their distributions along latitudinal and elevational gradients.

“…En Argentina, el último hallazgo se hizo en humedales asociados al Río Paraná, en la provincia de Santa Fe (Paggi & José de Paggi, 1974), momento a partir del cual no volvió a encontrarse hasta este estudio. Debido a que se la consideraba una especie endémica de la cuenca del Paraná -del Plata, su registro en el norte de La Pampa permitió comprobar que su distribución se extiende hacia el oeste, por fuera de esa cuenca, aunque se corroboró su tendencia a ha- Boeckella bergi es una especie que tiene una amplia distribución, ya que ha sido encontrada en cuerpos de agua de la meseta patagónica y se extiende hacia el noreste, en la provincia de Buenos Aires, Santa Fe y Entre Ríos (Menu Marque & Locascio de Mitrovich, 1998;Menu Marque et al, 2000), alcanzando su registro más septentrional en Santa Catarina, en el sur de Brasil (Previattelli et al, 2015) y se caracteriza por ser la única especie del género que ha colonizado exitosamente ecosistemas lóticos, en la cuenca del Paraná -del Plata (Menu Marque & Locascio de Mitrovich, 1998). En el caso de esta especie, el hallazgo en La Pampa, casi en el centro de su área de distribución permite suponer que es probable que la especie estuviera previamente, sólo que no había sido registrada debido a la carencia de estudios limnológicos en ecosistemas de muy baja salinidad.…”

Diversity of zooplankton in aquatic ecosystems of the northeast of La Pampa (Argentina) with emphasis on new species registered for the province.The northeastern region of La Pampa province has a large number of heterogenic aquatic ecosystems; however, limnological studies of these ecosystems are scarce. The objective of this study is to describe the composition of the zooplankton of five water bodies and report the presence of six species not previously registered in the province. Between 2016 and 2017, samples were taken in two small, highly transparent subsaline lakes ("water holes") with rooted vegetation and in three sub-or hyposaline shallow lakes, without vegetation and with less transparency. Eight cladocerans, nine copepods, and 27 rotifers were recorded. In all cases, rotifers dominated in number of species and density, but the zooplankton communities of the water holes differed from those of the shallow lakes. The aquatic ecosystems studied are in a reduced geographic area, but their diversity was greater than that of larger areas of La Pampa, which may be due to the heterogeneity of the water bodies included in this study. Three copepods (Argyrodiaptomus bergi, Boeckella bergi, and Eucyclops neumani) and three rotifers (Euchlanis dilatata, Lecane closterocerca, and Plationus patulus) have been identified for the first time in La Pampa province. This study confirms that the distribution of A. bergi and E. neumani is wider than known so far, which was restricted to Brazil and the Paraná -del Plata basin, but the remaining zooplankton are species widely distributed in Argentina. Thus, the lack of information in La Pampa was due to the absence of previous investigations.
