Hybridization and speciation
A perspective on the context and evolutionary significance of hybridization during speciation is offered, highlighting issues of current interest and debate and suggesting that the Dobzhansky–Muller model of hybrid incompatibilities requires a broader interpretation.
Character Displacement: Ecological And Reproductive Responses To A Common Evolutionary Problem
- K. Pfennig, D. Pfennig
- BiologyThe Quarterly review of biology

Understanding how organisms respond to competitive and reproductive interactions with heterospecifics offers key insights into the evolutionary causes and consequences of species coexistence and diversification.
Female spadefoot toads compromise on mate quality to ensure conspecific matings

The results suggest that the interaction between species and mate-quality recognition may influence mate choice decisions in important and nonintuitive ways.
The evolution of mate choice and the potential for conflict between species and mate–quality recognition
- K. Pfennig
- BiologyProceedings of the Royal Society of London…
- 22 September 1998
When a conflict may occur between species and mate–quality recognition is suggested, the evolutionary consequences stemming from this conflict are discussed, and a model of mate–preference evolution in response to heterospecifics is presented.

This video shows how to avoid look-alikes of venomous snakes when the real thing is around, as well as how to spot them when they are not.
Facultative Mate Choice Drives Adaptive Hybridization
- K. Pfennig
- BiologyScience
- 9 November 2007
Female spadefoot toads were more likely to choose heterospecific males when exposed to environmental conditions that favor hybridization, suggesting that females may radically alter their mate selection in response to their own phenotype and their environment, even to the point of choosing males of other species.
Nesting Success of a Disturbance‐Dependent Songbird on Different Kinds of Edges
- A. Suarez, K. Pfennig, S. Robinson
- Environmental Science
- 1 August 1997
We compared the nesting success of a disturbance‐dependent species, the Indigo Bunting ( Passerina cyanea), on different kinds of habitat edges in five sites (225 total nests) in southern Illinois…
Evolution's Wedge: Competition and the Origins of Diversity
- D. Pfennig, K. Pfennig

- 25 October 2012
This book discusses Character Displacement, Sexual Selection, and the Evolution of Isolating Mechanisms of Divergence in the Niche Partitioning of Resources and Reproduction.
Comparing Adaptive Radiations Across Space, Time, and Taxa.
- R. Gillespie, Gordon M. Bennett, Guinevere O U Wogan
- Environmental Science, BiologyJournal of Heredity
- 1 January 2020
A broad view of what constitutes an adaptive radiation is taken, and commonalities are sought among disparate examples, ranging from plants to invertebrate and vertebrate animals, and remote islands to lakes and continents, to better understand processes shared across adaptive radiations.
DIFFERENTIAL SELECTION TO AVOID HYBRIDIZATION IN TWO TOAD SPECIES
- K. Pfennig, M. Simovich
- BiologyEvolution; international journal of organic…
- 1 September 2002
Examination of the frequency and fitness effects of hybridization between plains spadefoot toads and New Mexico spade foot toads suggests that, although S. multiplicata females are under selection to avoid hybridization, selection might favor those S. bombifrons females that hybridize with S.multiplicata if their breeding pond is highly ephemeral.
