“…Such endemic species may be used as indicators of ancient lakes. However, Tyrrhenocythere donetziensis, probably a synonym of T. amnicola, was described from a slightly brackish lake (Griffiths et al 2002) and, therefore, could be classified as a non-marine species. However, it is rare in the Aral Sea and thus its uncertain classification does not change the position of the Aral Sea in the ternary plot.…”

The ostracod Cyprideis torosa (Jones) tolerates a wide range of salinity from fresh to brackish water-transition to hyperhaline values. The species often dominates ostracod assemblages in oligohaline and hyperhaline waters. For a more precise determination of controlling ecological factors, mainly the salinity, the accompanying ostracod fauna needs to be investigated. In oligohaline inland water bodies of humid climates, C. torosa is associated with tolerant non-marine ostracods. In coastal lagoons the mostly very low-diversity ostracod assemblages are characterized by brackish taxa accompanying C. torosa. In saline lakes of arid climatic zones non-marine and brackish species occur together, but brackish ostracods frequently dominate the assemblages. Monospecific occurrences of C. torosa are realized mainly in hypersaline environments. Examples are given that represent typical ostracod taxa that co-occur with C. torosa.

Some species (Limnocythere inopinata, Darwinula stevensoni, Ilyocypris echinata) are typical of the benthos of shallow areas, whereas Candona angulata, C. candida, Cryptocandona reducta, Cypria ophthalmica, Cyclocypris ovum, Cytherissa lacustris, Potamocypris smaragdina or Limnocythere sancti-patricii can be also present in the deeper benthos ([40 m deep) (Griffiths et al 2002;Li et al 2010).…”

This paper revises the response of freshwater ostracods to different environmental conditions and anthropogenic impacts, with a worldwide overview of the potential use of these microcrustaceans as bioindicators and several examples of applications in different scenarios. The development of either a single species or an ostracod assemblage is influenced by physical-chemical properties of waters (salinity, temperature, pH, dissolved oxygen), hydraulic conditions, bottom grain sizes or sedimentation rates. In addition to population and community changes, morphological and geochemical changes can also be detected in the ostracod carapace, which serves as a tracer of the water quality. All these features permit to delimit the spatial effects of urban sewages, mining effluents, agricultural wastes, watershed deforestation or road building. These data are the basis for the palaeoenvironmental reconstruction of cores, with an interesting application to archaeology. In addition, favourable results of recently developed bioassays, coupled with an important variability of local assemblages under changing conditions in both waters and sediments, suggest that these microcrustaceans may included between the most promising sentinels groups in freshwater areas. These microcrustaceans show high sensitivity to pesticides, herbicides, heavy metal pollution and oil inputs.

“…Sea-level curves ( Figure 6) suggest that terrace B may have been formed around 55,000-60,000 yrs BP and terrace C prior to about 70,000 yrs BP. Further support for this inference comes from the terrestrial pollen record, including evidence from the well-dated lacustrine sequences from Ioannina in the north-west of Greece (Tzedakis et al, 2002) and Kopais on the Boetian plain, located less than 40 km south of Arkitsa (Tzedakis, 1999) Terrace data therefore suggest uplift at average rates of 1-1.5 mm/y beyond the Holocene in the late Pleistocene, to at least 40,000 yrs BP. This estimated uplift rate is significantly higher than the long-term (footwall) uplift rate of 0.2 mm/y calculated by Goldsworthy and Jackson (2001) for the eastern end of the Arkitsa fault segment (also reported by Walker et al, (2010)), and while it agrees well with Late Holocene uplift rates of 1-1.4 mm/y proposed by Cundy et al, (2010) based on nearby slightly uplifted marginal marine units around Alope, it poses significant problems in terms of fault dynamics and extension rates in the area.…”

“…ostracods (e.g. Meisch, 2000;Griffiths, 2002;Alvarez-Zarikian, 2008), the faunal evidence points to a shallow, freshwater or very slightly brackish lake / lagoonal margin. Based on the discussion above, it is likely that these terraces were formed in earlier phases of OIS 3 and OIS 4 during relative high stand periods, and then uplifted to their present elevations.…”

14The Arkitsa-Kamena Vourla area of central Greece occupies a zone of accommodation 15 between the two tectonic provinces of the North Aegean Trough (the extension of the 16 North Anatolian fault system) and the Gulf of Corinth, and is characterised by a series 17 of very prominent tectonic landforms, notably the large (ca. 1000 m elevation) 18 footwall ridge of the Arkitsa-Kamena Vourla fault system. Despite the highly prominent 19 nature of this footwall ridge and the presence of very fresh tectonic landforms this 20 fault system is not known to have hosted any major historical earthquakes, and the 21 tectonic and geomorphic evolution of the Arkitsa-Kamena Vourla area remains poorly 22 constrained. This paper utilises a combined geomorphological, sedimentological and 23 macro-/micro-fossil approach to evaluate the Late Quaternary evolution of the Arkitsa 24 area, in the eastern part of the fault system, focussing on prominent uplifted terraces 25 present in the hangingwall of the Arkitsa fault. Three distinct raised glacio-lacustrine 26 terraces, and previously reported uplifted marginal marine deposits, suggest sustained 27 uplift of the coastline at a rate of 1 -1.5 mm/y over at least the last 40,000 years, 28 possibly to 75,000 BP. While movement on an offshore normal fault strand may 29 explain more recent coastal uplift, purely fault-driven longer-term uplift at this rate 30 requires anomalously high fault slip and extension rates. Consequently, the 31 development of the terraces and other geomorphic indicators of uplift may be at least 32 partly due to non-faulting processes, such as Quaternary (intrusive and/or extrusive) 33 volcanic activity associated with evolution of the nearby Lichades volcanic centre. 34 35
