“…The distinction between A. d. desmarestii, A. d. orientalis and A. d. mesopotamica is based mainly on features of the endopod of the male first pleopod (BOUVIER, 1925;AL-ADHUB, 1987). From Table 2, it is obvious that the number of setae on the outer margin, and the number of spines on the inner margin, varies in our material and overlaps with the literature data.…”

In order to elucidate the distinction of Atyaephyra desmarestii subspecies (A. d. desmarestii, A. d. orientalis, A. d. stankoi and A. d. mesopotamica ) and investigate their geographical distribution in Greece, the main morphological features and somatometric ratios were studied in numerous specimens collected from a dense station network of Greek fresh waters. Specimens from Belgium, Portugal, Albania and Turkey were also examined. Atyaephyra desmarestii was found in western and northern Greece while it was absent in eastern Greece , the Aegean and the Ionian islands. The comparison of the obtained data with those of the literature revealed a clearly overlapping variability of the main key morphological features among the four subspecies. The results of this study indicate that the current A. desmarestii subspecies are not valid on the basis of the used key features. There is only one very variable species with many ecophenotypes.

“…The upper region of the Shatt al-Arab is oligohaline (S ¼ 1.3-2.7 ppt) with a spring tidal amplitude range of 0.3-0.5 m between ebb and flood. Adult C. babaulti basrensis live in dense stands of hornwort (Ceratophyllum demersum) with another atyid shrimp, Atyaephyra desmaresti mesopotamica and the hymenosomatid crab, Elamenopsis kempi (Al-Adhub 1987;Al-Adhub & Hamzah 1987;Ali et al 1995). Gravid female C. babaulti basrensis appear in the hornwort starting in March until October.…”

Peak release of zoea I larvae of the warmwater shrimp, Caridina babaulti basrensis (Al-Adhub AHY 1987) in the field coincided with the highest summer water temperature (33 C). Zoea I abundances did not correlate significantly with the phase of the lunar cycle ( p ¼ 0.256) and only slightly with time of day (day : night regimes, p ¼ 0.079). Temperature correlated significantly with zoeae I larval release in the field ( p < 0.0001). Development and respiration were measured at constant water temperatures ranging from 20 to 35 C in coordination with the temporal distribution of larvae in the field. Cumulative duration for the development of the larval phase of C. babaulti basrensis was 11.4, 7.7, and 6.1 days at 25, 30, and 35 C, respectively. Larvae were unable to complete development at 20 C. Respiration rate for larval C. babaulti basrensis increased in direct proportion to temperature, and revealed metabolic stress at high temperatures. Laboratory rearing supported field data, which indicated a constraint on the presence of stage I zoeae in the plankton at lower temperatures (20 C). Although some larval stages may be metabolically stressed at higher temperatures, rapid development rates accomplished at higher temperatures may be a likely mechanism for retention within the habitat and recruitment to the adult population.
