The colonization history and present-day population structure of the European great tit (Parus major major)
Article Abstract:
The present-day population structure and colonization history of the European great tit (Parus major major) have been studied in eight populations from Northern Finland to Spain through use of mitochondial control region sequences. The study found one major haplotype in all but one of the populations. No population structuring was seen and the haplotypes unlike the common one had only a few substitutions. The estimated time to the most recent common ancestor is about the time to the last glacial period and results imply that that P. m. major survived that period in one isolated refuge, likely near the Mediterranean Sea. Rapid colonization of the continent and population growth ensued with northward expansion still going on. Gene flow is extensive.

Parasitism and the retrotransposon life cycle in plants: A hitchhiker's guide to the genome
Article Abstract:
A study of the retrotransposon life cycle of plants reveals that for retroviruses and retrotransposons, individual defective copies can parasitize the activity of functional ones. The various steps of the retrotransposon life cycle within the framework of the retroviral model are explored and the causes and possible consequences of lack of function at each stage are considered.

A dense linkage map of hybrid cottonwood (Populus fremontii x P. angustifolia) contributes a long-term ecological research and comparison mapping in a model forest tree
Article Abstract:
Genetic mapping in ecological genetic or genomic research helps to link genetic-level factors with community composition and ecosystem-level processes. A high-density amplified fragment length polymorphisms linkage map from a backcross population of hybrid cottonwoods is created to enhance comparisons of genome structure among multiple species within the genus.
