These investigations, however, were conducted on datasets for which it was quite likely that shortest trees could be encountered without much search effort per iteration because size and homoplasy still allowed that shortest trees could be found with intermediate effort without algorithms designed for particularly large datasets.
While we only report the change in prairie dog colony sizes from 1988 and 2005, intermediate mapping efforts in 1996 and 2000 showed that the loss of prairie dog colonies was a continuous process [46], [48].
Our results indicate that intermediate harvesting efforts offer an acceptable compromise between avoiding harvest-induced evolutionary change and securing high average yields.
This is closer to the predicted 5 cycles of annual MDA required to achieve long-term disease control for this country (Table 2) in contrast to the 10 annual cycles needed to achieve parasite elimination or 100% parasite control, and further supports the soundness of a disease control option as a first phase intermediate objective in efforts to eradicate LF.
Although there was high variability in sighting frequency at intermediate levels of effort (i.e. 50 500 dives), there were no significant trends of sighting frequency with survey effort for all sharks (slope = −0.002, S.E. = 0.003, p = 0.28) or for all sharks excluding nurse sharks (slope = −0.002, S.E. = 0.002, p = 0.41) (Fig. 2).
Sorensen asks us to imagine a third agent, Lori, who performs the same kind of donation for the same reasons, but who exerts an amount of effort intermediate between that exerted by Janette and Nigel: "Lori feels a variety of self-interested desires to keep the money or spend it on something for herself.
The success of control strategies in preserving oaks (species 2) is remarkably sensitive to intermediate levels of detection efforts (c.f.
The result of these efforts, the Intermediate-Range Nuclear Forces Treaty (1987), committed the United States and the Soviet Union to the complete elimination of their stocks of intermediate- and medium-range land-based missiles.
The fourth group of hypotheses assumes that perennial herbs probably have 'experimented' with increased allocation to sexual reproduction or that short-lived perennials and annuals with gene-flow from perennial relatives have 'experimented' with increased lifespan, but that the forms with intermediate lifespan and reproductive effort never had increased fitness because of tradeoffs.
The optimal frequency during the overall heating process, which is always lower than that at the initial temperature, can be evaluated from the intermediate temperature with low computational effort.
