Instead, adaptation may not be mutation-limited, or the distribution of fitness effects for beneficial mutations might differ vastly between different species or populations.
Therefore, the neural mechanisms of adaptation to the sound signals might differ in silent and noisy environments.
We hypothesized that local adaptation of the hosts results in differences in parasite resistance with variation in parasite infection rates and leukocyte activation, whereas parasites from different origins might differ in virulence reflected in host exploitation rates (parasite indices) and S. solidus excretory-secretory products (SsESP) involved in immune manipulation.
Thus, we might expect that if we could take a snapshot of Pacific salmon populations at several times in the past, we would consistently find (as we do now) a mosaic pattern of local adaptation, but that the fine-scale details of the pattern might differ across time periods.
It might differ slightly from the originally published version.
However, species in the earliest stages of speciation might differ only in a few genes that are responsible for differential adaptation or reproductive isolation.
On this basis, the optimal number of matings and offspring per mating for females might differ from those for males, resulting in sexual conflict over mating traits [ 11], and cause antagonistic adaptations and counter-adaptations between male and female traits [ 12],[ 13].
He allowed, though, that his peers might differ some.
These simplifications might differ slightly from what happens in vivo.
And when they are developed, they might differ from place to place.
Evaluations and prescriptions might differ, but a causal link between diet and character was generally accepted.
