Reproductive isolation grows on trees

Trends in Ecology & Evolution, 2009
Despite rapid advances in the complementary fields of speciation genetics and molecular phylogenetics, little attention has been devoted to understanding how genetic changes associated with reproductive isolation accumulate across clades of species. We argue that comparative analyses of reproductive isolation QTL (quantitative trait loci) can generate ...

Reproductive isolation in Damselflies

Systematic Biology, 1974
Paulson, D. R. (Department of Zoology, University of Washington, Seattle, Washington 98195) 1974. Reproductive Isolation in Damselflies. Syst. Zool. 23:40-49.-Experiments were performed in the field on males of five species and females of ten species of damselflies (Odonata: Zygoptera: Coenagrionidae) to determine the relative importance of visual and ...

MOLECULAR CORRELATES OF REPRODUCTIVE ISOLATION

Evolution, 2002
Evolution of reproductive isolation as a byproduct of genetic divergence in isolated populations is the dominant (albeit not exclusive) mode of speciation in sexual animals. But little is known about the factors linking speciation to general divergence.

ACO/CO reproductive isolation

2023
We ask if three decades and over 1 500 generations of divergent life history selection on age at reproduction has resulted in the evolution of reproductive isolation (RI) between laboratory populations of Drosophila melanogaster. We tested for premating, postmating-prezygotic and postzygotic reproductive isolation between 3 replicate population pairs ...

Reproductive isolation in birds: postcopulatory prezygotic barriers

Trends in Ecology & Evolution, 2007
Reproductive isolation is an important part of the speciation process. Recent studies of birds have highlighted not only the significance of postcopulatory postzygotic barriers, but also the almost complete absence of information about postcopulatory prezygotic barriers.

Reproductive Isolation Concepts

2018
The notion that species are kinds of organisms delineated not by the decisions of the classifiers but by the reproductive behaviors and results of the organisms themselves is an old one. Modern views of species are widely known and discussed except for the ways that the most well-known reproductive isolation concept, the class of which we shall call ...

Natural Hybridization and Reproductive Isolation

2021
In this chapter, cases of natural hybridization between Ohomopterus species are reviewed, and the mechanisms of reproductive isolation are considered. Hybrid zones are found between parapatric species within species groups, which exhibit similar body sizes.

Reproductive isolation among Sphyrapicus sapsuckers

2022
The question “How and why do species split?” is the central motivation for this dissertation. Evolutionary biologists have long attributed this speciation process to barriers that interrupt gene flow, such as biological differences between populations that constrain gene exchange and cause isolation among formerly reproducing groups. However, more work

The origins of reproductive isolation in plants

New Phytologist, 2015
SummaryReproductive isolation in plants occurs through multiple barriers that restrict gene flow between populations, but their origins remain uncertain. Work in the past decade has shown that postpollination barriers, such as the failure to form hybrid seeds or sterility of hybrid offspring, are often less strong than prepollination barriers.
