Rapid evolutionary changes in invasion-related ecological traits of alien plants are receiving considerable attention in current ecological research.
Where these niche shifts also include changes in genotype frequencies and morphological traits, these alien invaders may reflect the initial stage of speciation, especially if reproductive isolation follows as is the case for asexual species.
Truly becoming Bridget, which means being blunt, impolitic, gossipy, envious, needy and a little too obvious about everything, must have been like acquiring the traits of an alien.
For Smith, altered states of consciousness were mainly tools for the whiteous and righteous to vaporise whole solar systems of subversives, aliens and others with undesirable traits.
Invasiveness of some alien plants is associated with their traits, plastic responses to environmental conditions and interpopulation differentiation.
We analyzed a model of a coevolving community by focusing on competing consumer species with an evolvable trait and the invasion of an alien predator species and/or resource species into the community.
With respect to plant traits, there were 90 annual species, 174 alien species, 169 pollen allergenic species, and 133 species with edible or pharmaceutical value.
Hawking, however, warned against shouting into the cosmos, because some advanced alien civilisations might possess the same violent, aggressive and genocidal traits found among humans.
It's a fairly complex experiment, but to simplify, the first generation learned and attempted to remember the traits associated with each of several categories of alien.
The aliens they invented each had a different colour, shape and set of personality traits; such as arrogance, pushiness or selfishness.
