Characterization of Three Populations of Phallocryptus Spinosa (Branchiopoda, Crustacea) from North-East of Algeria

摘要: Phallocryptus spinosa (Thamnocephalidae), which was long considered as Branchinella spinosa, lives in saline lakes of America, Africa, and occidental Asia. There are very few data on its biology ecology. It has been recently found the Eastern Hauts Plateaux Algeria co-occurs with Artemia salina Sebkha Ez-Zemoul. Three populations have studied focusing their biometrics reproduction. During sampling period April 2005, only adults (more than 90%) some pre-adults were found. Adults short (16.14 ± 1.1–17.84 2.65 mm) compared to Mediterranean populations. No differences between total lengths males females. The latter oviparous begin reproduce when they reach length at least 11.5 mm. They not fertile (15.6 8.45–27.65 14.49 cyst/brood) produce cysts a mean diameter range 276.28 18.79 292.18 21.81 μm, according population.
