The role of forest genetic resources in responding to biotic and abiotic factors in the context of anthropogenic climate change [PDF]

open access: yes, 2015
The current distribution of forest genetic resources on Earth is the result of a combination of natural processes and human actions. Over time, tree populations have become adapted to their habitats including the local ecological disturbances they face ...

Endangered Plants in Novel Urban Ecosystems Are Filtered by Strategy Type and Dispersal Syndrome, Not by Spatial Dependence on Natural Remnants [PDF]

open access: yes, 2020
Understanding the contribution of cities to nature conservation is gaining increasing importance with a globally accelerating urbanization and requires insights into the mechanisms that underlie urban distribution patterns. While a considerable number of

Factorial analysis of bootstrap variances of population genetic parameter estimates

open access: yesGenetics and Molecular Biology, 2006
We presented an alternative way to verify the relative contribution to the total variance, of the sources of variation due to populations (P), individuals within populations (I), the (P*I) interaction, and the standard error of the following parameter ...
