"alter selection" is a grammatically correct phrase and can be used in written English.
It means to change or modify the choices or options available. Example: The company decided to alter their selection of products to appeal to a wider market.
Anthropogenic habitat alteration creates novel environments that can alter selection pressures.
Global environmental change is expected to alter selection pressures in many biological systems1,2,3, but the long-term molecular and life history data required to quantify changes in selection are rare4.
Consequently, variation in the age-trajectories of survival and fertility among populations do not greatly alter selection on alleles involved in susceptibility to late-onset diseases (in agreement with results from [3]), unless such changes alter the effective population size.
As all forms of female mate choice can significantly impact the strength and direction of sexual selection, any variation based on female age or experience may have important evolutionary implications that may alter selection for multiple male sexual traits [8], [14].
Any of these changes might decrease population size and alter selection, which might then cause maladaptation and reduced genetic variation (Johansson et al. 2007; McClure et al. 2008).
The present volume amplifies these intuitions by showing how human influences on salmon populations and their habitats can alter selection and lead to phenotypic change.
Hatchery fish experience altered selection pressures i.e. high juvenile density and abundance of food may select for behavioral and physiological traits that are disadvantageous in natural conditions [ 6].
The outcome should leave Sir Alex Ferguson in discomfort since the much altered selection he fielded proved not at all equipped for the task.
We conclude that the TI-2 antigen-induced altered selection of TD Ag-inducible clones and its severe gene-specific influence on further somatic mutations and affinity maturation represents a network memory, which we hypothesize to be mediated by anti-idiotypic regulatory T cells.
These newly altered habitats represent novel environments that impose strongly altered selection regimes.
Under these scenarios, relative responses to selection can be recalculated with appropriately altered selection intensities.
