More Bang For Your Buck: Quorum-Sensing Capabilities Improve the Efficacy of Suicidal Altruism
Anya Elaine Johnson, Eli Strauss, Rodney Pickett +3
Within the context of evolution, an altruistic act that benefits the receiving individual at the expense of the acting individual is a puzzling phenomenon. An extreme form of altru…
Behavioral Strategy Chases Promote the Evolution of Prey Intelligence
Aaron P Wagner, Luis Zaman, Ian Dworkin +1
Predator-prey coevolution is commonly thought to result in reciprocal arms races that produce increasingly extreme and complex traits. However, such directional change is not inevi…
From Cues to Signals: Evolution of Interspecific Communication Via Aposematism and Mimicry in a Predator-Prey System
Kenna D. S. Lehmann, Brian W. Goldman, Ian Dworkin +2
Current evolutionary theory suggests that many natural signaling systems evolved from preexisting cues. In aposematic systems, prey warning signals benefit both predator and prey.…
Causes and Consequences of genetic background effects illuminated by integrative genomic analysis
Christopher H. Chandler, Sudarshan Chari, David Tack +1
The phenotypic consequences of individual mutations are modulated by the wild type genetic background in which they occur.Although such background dependence is widely observed, we…
Does your gene need a background check? How genetic background impacts the analysis of mutations, genes, and evolution
Chris H. Chandler, Sudarshan Chari, Ian Dworkin
The premise of genetic analysis is that a causal link exists between phenotypic and allelic variation. Yet it has long been documented that mutant phenotypes are not a simple resul…
An experimental test for genetic constraints in Drosophila melanogaster
Ian Dworkin, David Tack, Jarrod Hadfield
In addition to natural selection, adaptive evolution requires genetic variation to proceed. Yet the G-matrix may have limited 'genetic degrees of freedom', with certain combination…
