The divergence of HIFLEX and LOFLEX could represent different adaptations to environments differing in mean quality and variability, or indicate that a genetic polymorphism of reproductive investment reaction norms has evolved under a physiological tradeoff between reproductive investment flexibility and adult lifespan.
The hypothesis states, first, that populations may show different adaptations due to spatially differing selective environments, and second, that males and females that differ ecologically (e.g. in reproductive behavior, in host use patterns) will respond to selective environments in distinct ways.
Moreover, species respond differently to climate change because of different adaptations to their environment [ 2].
Although the specific drivers and mechanisms are only partly resolved, our results indicate that the four clusters may exhibit different adaptations and therefore could respond differently to climate change.
This differing environmental aspect in EC obviously selects for different adaptations in the organisms' survival, and solar ultraviolet radiation (UVR) is one of the major selection agents in EC influencing the organism-environment interaction.
The groups exhibit different adaptations following application of the load, ultimately erasing group differences in the loaded condition.
The coming together of these two species with very narrow but different adaptations, along with allotetraploidy, has produced a transgressive hybrid with a broad adaptive range.
Therefore, in spite of the difference in anesthesia and rat strain among studies, it is likely that different adaptations in central cardiovascular control can be evoked by different approaches of exercise, intensity, and period of exercise training.
Bradbury's classic novel has attracted many different adaptations in its time, most notably François Truffaut's 1966 film and a BBC radio dramatisation, broadcast in 1982.
"Lyle, Lyle, Crocodile" also inspired two different adaptations: an animated musical that was shown on HBO and a theatrical musical staged by Theatreworks USA.
"What this suggests is that we do see a lot of different adaptations to different environmental conditions throughout the broad geographic range," he said.
