Triplophysa fishes are the primary component of the fish fauna on the Tibetan Plateau and are well adapted to the high-altitude environment. Despite the importance of Triplophysa fishes on the plateau, the genetic mechanisms of the adaptations of these fishes to this high-altitude environment remain poorly understood. In this study, we generated the transcriptome sequences for three Triplophysa...

Experiments on the capacity of the isolated teleost blastoderm to undergo development when cultivated in vitro have revealed species differences in the time of initiation of blastoderm differentiation. Thus the Fundulus blastoderm acquires the ability to develop after being separated from the yolk at the stage of 32 blastomeres (Oppenheimer, 1936) while the blastoderms of pike and of salmon dif...

Some properties and characterizations for abundant semigroups with generalised quasiadequate transversals are explored. In such semigroups, an interesting property [?a,b ? Re1S, VSo(a) VSo (b) 0 (a) = (b)] is investigated thus the concept of refined quasi-adequate transversals, short, RGQA introduced. It shown that real common generalisations both orthodox adequate in case. Finally, by means tw...

25 The prey selectivity of fish depends largely on traits of prey and predator. Preferable prey 26 traits might be different for visual predators (such as drift-feeding salmonids) and rather non27 visual predators (such as benthic feeders). We evaluated the explanatory power of five prey 28 traits and prey long-term abundance for the prey selection of small benthivorous fish by 29 analysing the...

BACKGROUND Androgenesis (all-male inheritance) is generally induced by means of irradiating the eggs to inactivate the maternal genome, followed by fertilization with normal sperm. In fish, the conventional technique for induced androgenesis has been applied for rapid fixation to traits, recovery of cryopreserved genotypes, sex-control, etc. A new method of androgenesis that eliminates the need...
