THE EFFECTS OF GENE FLOW ON REINFORCEMENT
Evolution, 1997We explore the possibility that differences in the pattern of gene flow between populations may affect the evolution of reinforcement by comparing pairs of populations undergoing one-way migration versus symmetric migration. The case of symmetric migration is modeled by a two-island model, where the two populations exchange equal proportions of ...

Gene expression is a highly interconnected multistep process. A recent meeting in Iguazu Falls, Argentina, highlighted the need to uncover both the molecular details of each single step as well as the mechanisms of coordination among processes in order to fully understand the expression of genes.

Evolutionary Anthropology: Issues, News, and Reviews, 2014
Debate over what is a species was already considered old hat when Darwin wrote his seminal abstract (as he called it) more than 150 years ago.1 Endless papers, workshops, and symposia have been presented in an effort to "solve" the species problem. Yet, here we are, at it again. Has there been any progress? I believe that there has been, and that among

Mechanisms of gene flow in archaea
Nature Reviews Microbiology, 2017Archaea are diverse, ecologically important, single-celled microorganisms. They have unique functions and features, such as methanogenesis and the composition of their cell envelope, although many characteristics are shared with the other domains of life, either through ancestry or through promiscuous horizontal gene transfer.

A survey of Australian cherry orchards identified the cherry cultivars Sunburst, Summit, Merchant, Sam, Sylvia, Tieton, Kordia, Regina, Empress, Nordwunder and Ulster as having low fruit-set associated with poor pollination. Unique orchard sites across Australia where low fruit-set was not a problem for these cultivars were located, and pollen gene ...

Gene flow in an almond orchard
Theoretical and Applied Genetics, 1991Gene flow by pollen between trees is essential for nut set in commercial almond orchards, due to the self-incompatibility of almond cultivars used. A study of gene flow has been carried out in an orchard composed of single rows of a "pollinating" cultivar between every double row of the most commercially desirable cultivar, Nonpareil. This "two-to-one"

In this chapter, we first present characteristics of carrots that will affect gene flow and discuss dispersal via pollen by insect pollinators and via seeds by wind and animals. Although carrot is often referred to as a biennial, we introduce the various life history strategies observed in wild carrot populations as these can impact population growth ...
