“…Only L. rionegroensis females were found in mixohaline (mesohaline) to oligohaline environments, and males were found in euhaline to mesohaline host waters such as Laguna Cari-Laufquen (Schwalb et al, 2002;Cusminsky et al, 2011). Our data agree with the observations made by Löffler (1990) who found males of L. inopinata only in strongly alkaline, and consequently with elevated solute concentrations, water bodies. More recently, studies of field populations of L. inopinata found bisexual populations from Chinese saline lakes and a asexual population from freshwater lake Mondsee (Yin et al, 1999) but in Turkey lakes, Reed et al (2012) did not find a simple relationship between salinity and the reproductive mode of L. inopinata.…”

Morphotypes of the lacustrine ostracod Limnocythere rionegroensis Cusminsky & Whatley from Patagonia, Argentina, shaped by aquatic environments

This study describes and quantifies morphological valve traits of the ostracod Limnocythere rionegroensis from Patagonian steppe lakes and explores their association with lake water characteristics. Surface ornamentation was examined by scanning electron and transmitted light microscopy, and valve size and shape were analyzed using morphometric techniques. Limnocythere rionegroensis shows remarkable variations in surface ornamentation, based on which three morphotypes (MI, MII, and MIII) were identified. Valves of morphotypes MI and MIII are larger, show slight to moderate external reticulation, and a higher shape variability, whereas MII is characterized by a very conspicuous reticulation, lower shape variability, and smaller valves. Outline analysis yielded a great shape disparity related to the dorsal margin slope. MI was found in sexual populations from euhaline to mesohaline ephemeral lake; MII occurs in parthenogenetic populations from mesohaline to oligohaline permanent or ephemeral lakes; and MIII, from both sexual and asexual populations, inhabits a broad range of environmental conditions in terms of salinity and stability. Limnocythere rionegroensis intraspecific variations may be caused by environmental parameters and genetic factors associated to reproductive strategies. These results contribute to the knowledge of extant L. rionegroensis morphological variability and provide additional clues to improve the environmental interpretation of fossil assemblages.

“…(Forester, 1983;Smith, 1993). The species is also tolerant of very high levels of chloride (Löffler, 1990): in North America, L. sappaensis has been reported in waters with chloride content up to 1241 meq l -1 (Forester et al, 2005).…”

“…In Europe, it shows geographical parthenogenesis since, although it is widespread, living sexual populations are known only in southeastern regions (e.g., Turkey) . In North America, Europe and Central Asia, males are associated with strongly alkaline water bodies (Delorme, 1971;Forester, 1983Forester, , 1986Löffler, 1990;Smith, 1993;Poberezhnaya et al, 2006). Sexual populations were more widespread in Europe during the Pleistocene and early Holocene (Griffiths & Horne, 1998;Horne & Martens, 1999).…”

Ostracods and the Holocene palaeolimnology of Lake Qarun, with special reference to past human–environment interactions in the Faiyum (Egypt)

et al. 2010

We present an ostracod record covering the past two millennia from an 8.25-m core taken from Lake Qarun, in the Faiyum Depression of Egypt. The occurrence of ostracod species in the lake is controlled primarily by variations in solute composition, which are in turn related to shifts in catchment land use. At times when the Faiyum Depression supported thriving agriculture, lake water contained Na ? -Cl -brine, and Cyprideis torosa dominated the ostracod assemblage. When the Faiyum Depression experienced periods of environmental and economic decline, lake water contained Na ? -HCO 3 -brine, and Limnocythere inopinata dominated. The relative abundance of other ostracod species provides additional information about past conditions in Lake Qarun including salinity and lake level changes. Overall, the ostracod assemblages provide evidence for human influences in the Faiyum, which extend back before instrumental or detailed observational records began.
