Studies comparing the adaptive value between resistant and susceptible barnyard grass biotype have shown that resistance to the herbicides propanil and clomazone does not alter the growth and competitiveness of the resistant biotype, suggesting that the frequency of alleles for resistance in the populations evaluated will likely remain stable in the absence of herbicide selection (Muthukumar et al., 2011).
The finding led the researchers to posit that green blood evolved independently in different lizards and may actually offer adaptive value or health benefits to the creatures.
"We hypothesise that these seasonal changes could have adaptive value," says L'e1zaro, who led the work.
The latter, which was mainly studied in rodents, has been interpreted as a character with adaptive value within underground tunnels in terms of echolocation (Roig, 1971), vocal communication (Schleich & Vasallo, 2003; Schleich & Busch; Francescoli et al.) and detection of predators (Ravicz & Rosowski, 1997; Schleich & Vasallo; Francescolli et al.).
Figure out adaptive value's average fitness [N.sub.avg] of the best individuals in all memeplexes.
The ability to focus attention and to filter unessential material is of obvious adaptive value. Complex and only marginally understood subsidiary processes are at work in these operations.
It may be only in such a society that the ability to follow pointing has adaptive value, or, more generally, elephant society may have selected for an ability to understand when others are trying to communicate with them, and they are thus able to work out what pointing is about when they see it." Byrne and study first author Anna Smet were studying elephants whose "day job" is taking tourists on elephant-back rides near Victoria Falls, in southern Africa.
His primary question concentrates on what adaptive value is served by specific behaviors, and he considers social, anti-predator, mating, and parental behavior, then presents examples of how the developmental and physiological mechanisms underlying animal behavior work and why they can be studied in terms of their adaptive value.
One particle presents a bird and it can calculate the adaptive value of its current position, and every particle records the optimal value searched by itself [15,16].
The theory that I shall seek to elaborate here puts considerable emphasis on the process of dealing with music, the difficulties of describing music experience in an objective way, the fundamental organizing principles of musical pitch, and the evolutionary adaptive value of music.
Understanding your current capacity for exertion--by assessing just how your current hardest workout stacks up against the workouts planned a few weeks and months from now--is crucial to maximizing the adaptive value of each workout.
