The Metropolitan Opera has revived its long-dormant production of Rossini's first big comic success.
Our data and models show that in a striking coincidence winter annual seeds are set when the mean temperature is approximately 14 15°C, the temperature at which a major switch from the production of dormant to non-dormant seeds occurs.
The short generation time allows monitoring responses in experimental evolution trials (Van Doorslaer et al. 2009b; Jansen et al. 2011), while the production of dormant stages (ephippia, Hebert 1978) that accumulate in dormant egg banks allows obtaining representative samples of the gene pool of natural populations.
One researcher even suggests that geneticists could activate one of the tomato's dormant genes, enabling capsaicinoid production and creating a plant that makes ready-made salsa.
The percent rate of diapausing prepupae differed seasonally, and was 20.0 37.5% (30.3 ± 7.5%, n = 3) in overwintered generation and 0 100% (50.0 ± 39.8%, n = 9) in first generation, suggesting that the rate of production of dormant prepupae increased toward the later activity season.
However, if these clones invest little or nothing into the production of dormant eggs, this may be an evolutionary trap.
Seed bank persistence requires that seed entry rate (production of dormant seeds) exceeds exit rate, the sum of germination, death or deep burial.
For example, the delayed production of dormant eggs for a seasonal diapause is a trait that may to warming waters and associated longer growth periods.
In a controlled laboratory study using the F1 generation of a copepod species (Labidocera aestiva), the production of dormant eggs was population specific, suggesting local adaptation of developmental mode to the length of the growing season, which is covarying with temperature (Marcus 1984).
The hope is that strong stage productions revitalise dormant filmed material with the energy of daily performance – which feeds back into the brand.
