Interactive effects of season and temperature on enzyme activities, tissue and whole animal respiratnvironmental change and that these responses of metabolism and behaviour are controlled by both endogenous and exogenous factors. The rate of oxygen consumption of gill and muscle tissue ‘brei’ from fish caught during a seasonal cycle and measured at 15° C appears to follow closely the reproductive

Influence of temperature and ambient oxygen on the swimming energetics of cyprinid larvae and juveni was more strongly dependent on temperature (Q. around 2.5) than the maximum active rate (Q. below 2). Whereas standard and routine respiration rates were well regulated over the pO.-range investigated (8.5–25.8 kPa), the active rates showed a conformer-like pattern, resulting in factorial scopes fo

How dams on the River Danube might have caused hybridization and influenced the appearance of a new r by dams built as part of the Rhein-Main-Donau Kanal. These impoundments, however, might be responsile not only for the creation of hybrids but also for direct speciation, as the case of . may represent. The ability for epigenetic creation of two alternative life-history states (as part of the theo

The role of predation and competition in determining the distribution of common bream, roach and whi water and avoided the littoral zone where it competed with roach. White bream occupied an intermediate position, occurring in relatively low density both in the littoral zone and in open water. The importance of predation and competition in determining the distribution and abundance of roach and co
