Physical performance is determined both by biophysical and physiological limitations and behav- ioral characteristic, specifically motivation. We applied an experimental evolution approach com- bined with pharmacological manipulation to test the hypothesis that evolution of increased aerobic exercise performance can be triggered by evolution of motivation to undertake physical activity. We used a unique model system： bank voles from A lines, selected for high swim-induced aerobic metabolism （VO2swim）, which achieved a 61% higher mass-adjusted VO2swim than those from un- selected C lines. Because the voles could float on the water surface with only a minimum activity, the maximum rate of metabolism achieved in that test depended not only on their aerobic capacity, but also on motivation to undertake intensive activity. Therefore, we hypothesized that signaling of neurotransmitters putatively involved in regulating physical activity （dopamine and noradrenaline） had changed in response to selection. We measured VO2swim after intraperitoneal injections of sa- line or the norepinephrine and dopamine reuptake inhibitor bupropion （20 mg/kg or 30 mg/kg）. Additionally, we measured forced-exercise VO2 （VO2max）. In C lines, VO2swim （mass-adjusted mean ± standard error （SE）： 4.0 ± 0.1 mLO2/min） was lower than VO2max （5.0 ± 0.1 mLO2/min）, but in A lines VO2swim （6.0 ± 0.1 mLO2/min） was as high as VO2max （6.0 ± 0.1 mLO2/min）. Thus, the selection effectively changed both the physiological-physical performance limit and mechanisms responsible for the willingness to undertake vigorous locomotor activity. Surprisingly, the drug had no effect on the achieved level of VO2swim. Thus, the results did not allow firm conclusions concerning involvement of these neurotransmitters in evolution of increased aerobic exercise performance in the experimental evolution model system.

We present experimental investigations and numerical simulations of a pseudo-2D riser. Experiments were performed for various airflow rates, particle types/diameters, and particle size distributions. Pres- sure distributions along the wall of the riser were measured, Additional measurements from a smaller pseudo-2D riser （Kallio et al., 2009; Shah et al., 2012） were used to analyze horizontal solids volume fraction profiles. The experimental data were compared with simulation results carried out using an Euler-Euler approach, A mesh sensitivity study was conducted for numerical simulations and effects associated with simplifying real 3D geometry to a 2D model were examined. In addition, the effect of using an algebraic equation to represent the granular temperature versus a full partial differential equation also was examined for numerical simulations. Results showed small but significant near-wall sensitivity of the flow variables to mesh size. Substantial differences in mean pressure, solids distribution, and solid velocities were obtained, when 2D and 3D simulation results were compared. Finally, applying the simplified granular temperature equation for turbulent fluidization and for dilute-phase transport can lead to incorrect predictions in models,

Morphological variation of snails from the genus Trochulus is so huge that their taxonomy is unclear. The greatest variability concerns forms hispidus and sericeus/plebeius, which are often considered as separate species. To evidence the species barriers, we carried out crossbreeding ex- periments between these two sympatric morphs. Moreover, we compared the shell morphology of laboratory-bred offspring with their wild parents to test if the variation can be explained by the phenotypic plasticity model. We found that the two Trochulus morphs show no reproductive bar- riers. The fecundity rates, the mean clutch size, and F~ viability observed for all crosses were not significantly different. In hybrid crosses （in F2 generation）, we also recorded reproduction compati- bility, similar fecundity, and hatching success as in their parents. Accordingly, phylogenetic ana- lyses revealed the significant grouping of sequences from these different morphs and supported no constrains in reproduction between them. Comparison of shell morphology between wild and laboratory samples showed that various characters appeared highly plastic. The average shell shape of the hispidus morph changed significantly from flat with wide umbilicus to elevated with narrower umbilicus such as in the sericeus/plebeius morph. All these findings indicate that the examined morphs do not represent separate biological species and the evolutionary process is not advanced enough to separate their genetic pool. Therefore, phenotypic plasticity has played a sig- nificant role in the evolution of Trochulus shell polymorphism. The two morphs can evolve inde- pendently in separate phylogenetic lineages under the influence of local environmental conditions.

Exercise performance depends on both physiological abilities (e.g., muscle strength) and behavioral characteristics (e.g., motivati on). We tested the hypothesis that evoluti on of in creased aerobic exercise performanee can be facilitated by evolution of neuropsychological mechanisms responsible for motivation to undertake physical activity. We used a unique model system: lines of bank voles Myodes glareolus selected for high swim-induced aerobic metabolism ("aerobic" A lines). In gen eration 21, voles from the 4 A lines achieved a 57% higher /y voluntary maximum" swiminduced aerobic metabolism (V02swim) than voles from 4 unselected,"control" C lines. In C lines, V02swim was 9% lower than the maximum forced-exercise aerobic metabolism (VO2run;P= 0.007), while in A lines it was even higher than VO2run, although not significantly (4%, P=0.15). Thus, we hypothesized that selection changed both the aerobic capacity and the neuronal mechanisms behi nd motivation to un dertake activity. We investigated the influe nee of reuptake in hibitors of dopamine (DARI), serotonin (SSRI), and norepinephrine (NERI) on VOaSwim. The drugs decreased V02swim both in C and A lines (% decrease compared with saline: DARI 8%, P< 0.001;SSRI 6%, P< 0.001;NERI 8%, P< 0.001), but the proportional response differed between selection directions only for NERI (stronger effect in C lines: P= 0.008) and the difference was marginally non-significant for SSRI (P= 0.07) and DARI (P= 0.06). Thus, the results suggest that all the 3 monoamines are involved in signaling pathways controlling the motivation to be active and that norepinephrine could have played a role in the evolution of increased aerobic exercise performance in our animal model.

Evolution of complex physiological adaptations could be driven by natural selection acting on behavioral traits. Consequently, animal personality traits and their correlation with physiological traits have become an engaging research area. Here, we applied a unique experimental evolution model lines of bank voles selected for (A) high exercise-induced aerobic metabolism,(H) ability to cope with low-quality herbivorous diet, and (P) intensity of predatory behavior, that is, traits shaping evoluti on ary path and diversity of mammals and asked how the selecti on affected the voles' personality traits, assessed in an open field test. The A- and P-line voles were more active, whereas the H-line voles were less active, compared those from unselected control lines (C). H-line voles moved slower but on more meandering trajectories, which indicated a more thorough explorati on, whereas the A- and P-line voles moved faster and on straighter trajectories. A-line voles showed also an increased escape propensity, whereas P-line voles tended to be bolder. The remarkable correlated responses to the selectio n indicate a comm on gen etic un derlying mecha nism of behavioral and physiological traits, and support the paradigm of evoluti on ary physiology built around the concept of correlated evolution of behavior and physiology.

Microbial deposits commonly occur at the transition between carbonate and sulphate facies,and they also abound in the uppermost part of the middle Wuchiapingian Zechstein Limestone in west *** deposits occur as isolated reefs of the basinal zone and in the condensed sequences in most parts of the study *** deposits of the latter category reflect evaporative drawdown,and the abrupt boundary between the carbonate and sulphate deposits in the basin suggests the nature of evaporites that start to precipitate as soon as they reach the saturation level.A few-metre-thick unit of mostly brecciated microbial deposits at the top,reefal portion of the Zechstein Limestone records extreme palaeoenvironmental events that occurred at the transition from carbonate to sulphate *** events are related first to subaerial exposure of the reef,which lasted several 10~5 years and then to the Lower Anhydrite transgression.

两位波兰总统候选人的区别更多是一种风格之异，而非实质之别。这样的选举也许不是那么动人心魄，但它本身就代表了波兰政冶体制的成功。它说明，波兰的政治正在走向折衷化，政治家在向中间派选民的立场靠近。
