terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...

Parabetaeus acanthus sp. nov. is described based on two specimens from Thuwal, Saudi Arabia, and Madang, Papua New Guinea. The new species is unique within the genus in possessing an anteriorly directed, spine-like tooth on the mid-dorsal line of the carapace, posterior to base of the eyes, and in the stylocerite not reaching the mid-length of the first article of the antennular peduncle. The c...

Sex identification is linked to sexual dimorphism and an important study issue in fish biology aquaculture. However, owing the unmarked heteromorphism between adult Hemibarbus labeo, it often difficult distinguish their sex by visual observation. This aimed find a simple reliable morphometric criterion for of H. labeo using discriminant models. Forty-two traits sixty-eight individuals collected...
