Dispersal

Kathryn Stoner is a research ecologist at the National University of Mexico. She has been studying how certain monkeys contribute to seed dispersal in a tropical forest in the southern Mexican state of Chiapas.

Valid concerns have been raised about how these factors and constraints may be eroding the genetic integrity and the wild character of bison that, for millennia, were shaped into resilient animals by the hands of natural selection and wide-ranging movements across large landscapes that allowed for natural dispersal and intermixing of herds.

For a time, Okeh picked up the disk for national dispersal.

Plant breeding is always a numbers game.[…]The wild species we use are rich in genetic variation, […]. In addition, we are looking for rare alleles, so the more plants we try, the better. These rarities may be new mutations, or they can be existing ones that are neutral—or are even selected against—in a wild population. A good example is mutations that disrupt seed dispersal, leaving the seeds on the heads long after they are ripe.
