Seasonal variation and influence of turbidity and salinity on the zooplankton of a saline lake in central Argentina

Abstract: ABSTRACT. The limnology of saline water bodies at other latitudes is fairly well known, but in Argentina such studies have only recently begun. The applicability of many conclusions regarding the functioning of these environments around the world is limited due to the scant ecological knowledge of some endemic species recorded in the assemblages of Argentine lakes. The aims of this work were to determine the effects of salinity and inorganic turbidity on the taxonomic composition, abundance, and zooplankton bi… Show more

“…Throughout the study, the halophilic (De los Ríos & Crespo 2004) and eurihaline character of B. poopoensis (Echaniz & Vignatti 2011, Echaniz et al 2013) was evidenced, since it was recorded in a relatively wide range of salinities. The species was always present in three lakes (Cha, SJ and Ut), but was recorded only from October in EC.…”

“…Este padrão também foi observado na Barra de Orange e Catuama por Figueiredo et al (2006); no mesmo rio estudado, por ; no Lago Salino Central, por Echaniz (2011). Observou-se que nas preamares, mesmo no período de maior pluviosidade, os índices de chuvas não foram suficientes para modificar de forma brusca a salinidade.…”

“…These activities are reflected in the high content of nutrients contributed by the fertilization of crops as well as by the feces and urine of cattle raised in the surrounding area. This is enhanced by the arheic character of the basins, which favors the concentration of nutrients both in water and in sediment (Echaniz et al 2009, 2010, Echaniz & Vignatti 2011. Goulden (1968) reported a maximum size of 1.5 mm for parthenogenetic females, but some specimens of the Pampean lakes, as well as some from Corrientes (Paggi 1997) and Rio de Janeiro, exceed this size (Elmoor-Loureiro et al 2010) (1.19 mm and 1.08 mm, respectively).…”

“…In the province of La Pampa, in the semi-arid central region of Argentina, although more than 100 water bodies have been surveyed since 1992, M. macrocopa was first recorded in December 1999, in a sub-saline shallow temporary lake (Bajo de La Tigra) and subsequently in other five water bodies (Echaniz et al 2005, Echaniz & Vignatti 2011, being last recorded in February 2007. Although its presence was reported, no specific information was provided.…”
