متن کاملsome biological characteristics of tadpole shrimp, triops cancriformis, from seasonal pools of west azarbaijan (iran)
the tadpole shrimp of genus triops is a well-known living fossil whose fundamental morphology has been unchanged for 220 million years. we collected specimens of triops cancriformis in temporary water bodies near the southern part of urmia lake (in the fall of 2005). some biological characteristics of this triops were investigated. the feeding re-gime of t. cancriformis was found to be related ...
متن کاملHyaluronidase from Tadpole Tissue.
The connective tissues of the tadpole undergo extensive remodeling during metamorphosis. In the resorbing tail fins of bullfrog tadpoles, there is a rapid degradation of collagen in the basement lamella coupled with dehydration and loss of the gelatinous core of the fin (1,2). The layers of the dense collagenous basement lamella are loosened, frayed, and invaded by mesenchymal cells.1 A collage...
متن کاملOptimal conditions for rearing the tadpole shrimp, Triops longicaudatus (Notostraca:Triopsidae), a biological control agent against mosquitoes.
Tadpole shrimp (TPS) were reared at 15, 20, 25, and 30 degrees C in the laboratory. Size of TPS was temperature and age dependent with more rapid development at warmer temperatures. Survivorship was inversely related to rearing temperature. Mean age at death was 24.2, 19.2, 14.3, and 11.8 days at 15, 20, 25, and 30 degrees C, respectively. Rearing temperature (excluding 15 degrees C) did not af...
متن کاملMetabolic, respiratory and cardiovascular responses to acute and chronic hypoxic exposure in tadpole shrimp Triops longicaudatus.
Hypoxic exposure experienced during sensitive developmental periods can shape adult physiological capabilities and define regulatory limits. Tadpole shrimp were reared under normoxic (19-21 kPa O(2)), moderate (10-13 kPa O(2)) or severe (1-3 kPa O(2)) hypoxic conditions to investigate the influence of developmental oxygen partial pressure (P(O(2))) on adult metabolic, respiratory and cardiovasc...
