Long-term studies show a decline in success rates with time.
Statistical information on the impact of NSF's budget reductions won't be available until March 2006, but the impact of such reductions on scientists in the trenches is bound to be substantial: If a 5% budget increase led to a 3% decline in success rates, what will be the impact on funding rates of a nearly 1% budget reduction?
Notre Dame, one of the biggest passing teams of the decade, saw a substantial decline in success; the 1950s were the only decade between 1920 and 1990 when the team did not win at least a share of the national title.
The steep decline in success beyond 2000 yr BP remains enigmatic, and deserves additional study.
City sources were saying yesterday that United's sheer size, income and dedicated following makes the bond issue an attractive enough offer – despite the "high degree of risk", including a possible fall in success, decline in crowds and uncertainty over who will replace Ferguson.
This contrasts markedly with other species, like earwigs, where untended eggs challenged with mold infection show far more dramatic declines in hatch success [ 42].
In ten simulations, where data were thinned to a constant sampling effort across time and number of PCR attempts per sample, age significantly affected amplification success (p < 0.001), confirming a decline in PCR success in older samples.
The stress-induced decline in reproductive success resulted from a cumulative decrease in mating success (from 88and90%0% in non-stressed groups to 43% in the stress-scrambled group, Figure 3D) and pregnancy rates in the females that mated (from 87 and 89% in non-stressed groups to 50% in the stress-scrambled group, Figure 3E).
The surviving population in Scotland then suffered a sharp decline in breeding success in the 1960s due to organochlorine pesticides which caused mass infertility.
Models developed by some scientists predict an increase in polar bear starvation as a result of longer ice-free seasons and a decline in mating success, since sea-ice fragmentation could reduce encounter rates between males and females.
