Cryptic Biological Invasions: a General Model of Hybridization
15 February 2018
The dispersal of non-native genes due to hybridization is a form of cryptic invasion with growing concern in evolution and conservation.
This includes the spread of transgenic genes and antibiotic resistance. To investigate how genes and phenotypes are transmitted in such situation, we developed a general model which includes genetic and demographic parameters and represents a powerful tool for the study of a wide range of biological and societal questions.
We used this model to show that mallard ducks introduced in New Zealand benefit from hybridization to replace native grey-ducks.
