of plants using microsatellites
Willow genetic diversity
are dioecious and can show clonal growth. In some cases, isolated
stands consist of plants all of one sex. This suggests that
at these sites individual populations may consist of one or
a few clones. In other cases both male and female plants coexist,
seed set occurs and there is the potential for sexual recruitment
and high levels of clonal diversity. Clones may differ in
a range of physical and biochemical characters, which while
often having a complicated underlying genetic base, nevertheless
represent attributes of a genotype that can affect its interaction
with its local abiotic and biotic environment.
the importance of the clonal composition of willows for interactions
with their local ecosystem requires an understanding of the
amounts and dynamics of genotypic diversity. For the current
project microsatellites were used to assess population
genetic structure. The known clonal diversity provided
a framework for comparisons with other ecosystem components.
In addition, both indirect and direct measures of gene flow
were made, which, coupled with studies on reproductive
ecology, aimed to provide insights into patterns of reproduction
and dispersal to guide conservation strategies for these species.
