Furthermore, it is important to determine whether introgression can occur under a diversity of selective environments, some of which may eliminate many, if not most, maladaptive crop-derived traits (i.e., when selective filters are strong).
To better match the phenotypes and selective environments, organisms adapt to the environmental conditions under which they live in by altering their behavior, physiology or morphology.
when selective environments appeared similar?
Slow leaching of these heavy metals under acidic environment during the degradation process leads to leachates with high metal concentrations.
How a species responds to these variable selection pressures depends on the details of the selective environment and the genetic variances and covariances for the traits under selection [3].
This suggests that the fish gut looks a lot more like the surrounding environment, and even more so under starvation conditions due to a limited selective environment as compared to mammals.
By simultaneously manipulating the selective environment and genetic diversity under controlled laboratory conditions with replication, we used A. bahia cultures to develop a more detailed understanding of the relationship between genetic diversity and population fitness in a changing environment.
Shortly later, channel estimations under frequency-selective environment were developed in [7, 8].
"It will be a more selective environment going forward, but many stocks will do very well".
The evidence was that viruses evolved under high co-infection (but not low co-infection) improved in fitness relative to the ancestor in their selective environment, at the expense of fitness improvement in the unselected environment [ 19].
Here we examine how RNA viruses evolve with demographic structure imposed by a phylogenetic tree, under selective conditions of novel host environments and parametrically varying population sizes.
