Parasite spill-back from domestic hosts may induce an Allee effect in wildlife hosts [PDF]

, 2012
The exchange of native pathogens between wild and domesticated animals can lead to novel disease dynamics. A simple model reveals that the spill-back of native parasites\ud from domestic to wild hosts may cause a demographic Allee effect.

Inheritance of nuclear DNA markers in gynogenetic haploid pink salmon [PDF]

Journal of Heredity, 1999
We describe the inheritance of 460 PCR-based loci in the polyploid-derived pink salmon (Oncorhynchus gorbuscha) genome using gynogenetic haploid embryos. We detected a length polymorphism in a growth hormone gene (GH-2) intron that is caused by an 81 bp insertion homologous to the 3' end of the salmonid short interspersed repetitive element (SINE) SmaI.
