Some biological aspects of Gammarus lacustris Sars, 1863 in Neur Lake Ardabeel province, Iran
A biological study was conducted to find out about reproduction and feeding of G. lacustris in Neur Lake from northwest mountains of Iran. Plankton diversity, hydro-chemical factors and substrate characteristic were recorded monthly. Findings showed that reproduction period of this species was short and limited to May and the mean brood size was 10.2 ± 5.3 eggs per female. The hydro-chemical an...

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولGlacial-driven vicariance in the amphipod Gammarus duebeni.
We have examined the genetic diversity using mitochondrial COI and ND2 sequence data from 306 specimens of the amphi-Atlantic-distributed amphipod Gammarus duebeni. Marine populations from the Atlantic Ocean, the Baltic and North Sea, as well as freshwater populations from Ireland, Cornwall and Brittany were analysed. G. duebeni is a complex of five allopatric lineages. Freshwater populations r...
متن کاملActivation of the Sodium Uptake System at High Blood Concentrations in the Amphipod Gammarus Duebeni.
In an earlier paper (Lockwood, 1961) it was shown that the brackish-water amphipod, Gammarus duebeni, begins to form urine hypotonic to the blood about 2 hr. after the animal is transferred from a highly concentrated medium (100-175% sea water) to fresh water. The osmotic concentration of the blood at the time the urine first becomes hypotonic may be as much as 1 M./l. NaCl, a value twice as hi...
