“…Temporary waters are generally shallow and strongly exposed to the mixing effect of wind (Lahr, Diallo, Ndour, Badji, & Diouf, 1999;Naganawa & Zagas, 2002). Besides, they are often visited by large wallowing mammals and waterfowl with obvious consequences for turbidity and mixing .…”

1. Omnivory is widespread in food webs, with an important stabilising effect.The strength of omnivorous trophic interactions may change considerably with changes in the local environment.2. Shallow temporary waters are often characterised by high levels of inorganic turbidity that may directly limit the food uptake of filter-feeding organisms, but there is little evidence on how it might affect omnivorous species. Anostracans are key species of temporary waters and recent evidence suggests that these organisms are omnivorous consumers of both phyto-and zooplankton.3. Using Branchinecta orientalis as a model species, our aim was to test how turbidity affects the feeding of an omnivorous anostracan. To do this, we used short-term feeding experiments and stable isotope analyses, with animals collected from soda pans in eastern Austria. In the feeding experiments, algae and zooplankton were offered as food either separately or in combination. The prey type treatments were crossed with turbidity levels in a factorial design.4. There was a pronounced decrease in the ingested algal biomass with increasing turbidity. Conversely, ingestion rates on zooplankton were less affected by turbidity. Stable isotope analyses from field material supported our experimental results by showing a positive relationship of the trophic position of anostracans and the trophic niche of the communities with turbidity. 5. Our results show that turbidity modulates the intraguild trophic relationship between anostracans and their prey by shifting the diet of anostracans from more herbivorous in transparent to more carnivorous in turbid waters. Thus, inorganic turbidity might also have a community-shaping role in plankton communities of temporary waters through altering trophic relationships.

“…Among the anostracans the most abundant and purely halophile species is Artemia sp., whose taxonomical status still remains unclear; it always forms bi-sexual populations, normally in the more saline (hypersaline) and persistent waters. considered not common in Mongolia; it was fi rstly discovered in Dundgovi province (Naganawa & Zagas, 2002) but according to present data its distribution can been enlarged to Tov, Dornod, Arkhangai and Suhbaatar provinces. G. murae, a Mongolian endemic species has been only seen in two localities, one in Bayan-Olgii and the another in Arkhangai.…”

This paper presents a very complete inventory of the branchiopods and copepods that inhabit the salt lakes (salinity >3‰) of Mongolia. The inventory was based on samples collected from 108 salt lakes over the course of seven limnological expeditions in most of the Mongolian territory between 2005 and 2009. The salinity of the lakes ranged from 3.4 to 76‰ S. A total of 43 taxa were identifi ed: 7 Anostraca, 1 Spinicaudata, 1 Notostraca, 1 Leptodoridae, 1 Ctenopoda, 15 Anomopoda and 17 Copepoda. Thirteen taxa are limited to the Asiatic portion and the rest are known throughout the Palearctic region. One taxon, Phallocryptus sp. has not yet been described in scientifi c literature. The taxonomic position of Artemia sp. in Mongolia has still not been clarifi ed. All of the species are eurysaline and, except for Artemia sp. and Cletocamptus retrogressus, which are the most halophile, they can live in waters with less than 10‰ S. Thirty-three species appear only in mesosaline waters (3–20‰ S), fi ve do not exceed the mesosaline level (50‰ S) and fi ve can live in hypersaline waters (>50‰ S).

“…Branchiopods and copepods of continental standing waters are well known in Spain (Alonso, 1996;1998); however, the information regarding these taxa in Mongolia is scattered and incomplete (Sars, 1903;Brtek et al, 1984;Naganawa & Zagas, 2002;Flossner et al, 2005;Penkova et al, 2005;Pomazkova & Sheveleva, 2006;Alonso & Naganawa, 2008;Sinev et al, 2009;Alonso, 2010;Alonso & Ventura, 2013). In fact, the most comprehensive inventory for this country is currently being performed by the author of this paper, with some of the taxa mentioned below only partially reported in the abovementioned publications.…”

On the possible use of Mongolian branchiopods and copepods to establish reference conditions for ecological quality assessment of lacustrine water bodies in Spain

On the possible use of Mongolian branchiopods and copepods to establish reference conditions for ecological quality assessment of lacustrine water bodies in SpainA comparison of assemblages of Branchiopoda and Copepoda living in lakes and wetlands in two very distant territories in the Palaearctic Region, the Iberian Peninsula and Mongolia, is presented. Both territories have significant similarities in the hydromorphological and physicochemical characteristics of their water bodies and in the structure and composition of their fauna of branchiopods and copepods. Some species occur in both areas, others are taxonomically closely related, and others behave as geographic vicariants. Most of these microcrustaceans are used as indicators of ecological quality of standing water bodies in industrialized European countries, where reference sites are frequently difficult to find. Taking into account the undisturbed conditions of Mongolian water bodies, the alternative of using their branchiopods and copepods, after setting the proper, statistically-based equivalence between Mongolian and Iberian species, as references to assess ecological status in Spain is discussed.
