Document Summary
#3: population genetics of the invasive giant hogweed ( heracleum sp. ) in a northern european region. Question: look at the population genetics of the giant hogweed and try to reveal characteristics or evolutionary processes that may point to why it"s such a successful invasive species. Where/what: northern range of its distribution in finland. Approach: comparative: they took dna samples from giant hogweed plants in different areas and compared them to look for variability. While diversity and differentiation is caused by evolution, invasive species aren"t as affected by these influences, and therefore are more affected by human activity. Thesis relation: giant hogweed affects native plant species by invading, and this study looks at the genetic aspects of invasive hogweed populations. #4: the impact of an invasive plant changes over time. Dostal p. , mullerova j. , pysek p. , pergl j. , and klinerova t. 2013. Approach: comparative: vegetation surveys using aerial photographs over time.
