Matrix-dimensionality in demographic analyses of plants: When to use smaller matrices?
Article Abstract:
A study is conducted which examines whether it is possible to use a smaller matrix dimensionality in plants that produces the reliable estimate of gamma. The use of a small matrix dimensionality is recommended especially when a limited amount of data is available and for slow-growing species having a simple matrix structure that mainly consists of stasis and growth to the next stage.

Genetic consequences of a demographic bottleneck in the Scandinavian arctic fox
Article Abstract:
Museum specimens were used to examine the genetic variation in the mtDNA and five microsatellite loci in the Scandinavian arctic fox population before the demographic bottleneck. It was found that the arctic foxes in Scandinavia have lost approximately 25% of the microsatellite alleles and four out of seven mtDNA haplotypes.

Disease dynamics, host specificity and pathogen persistence in isolated host populations
Article Abstract:
The spatial distribution of plant populations can have substantial effects on patterns of pathogen persistence and disease dynamics. Cross-species infections are possible at the sympatric site, and can increase the frequency of disease and lower the threshold level of pathogen persistence in populations.
