Quick Quiz Questions
may it be unreliable to predict the potential range of invasive species
based on environmental variables in the species native range?
are two ways genetically based mechanisms by which an invasive species can
adapt to novel environments in its new range? Which of these is supported by this
hypotheses do the authors propose to explain why Verbascum thapsus
has not invaded higher elevations in the Sierra Nevada?
were maternal effects controlled in the experimental design?
did they test performance to high elevation environments? What traits did they measure and why?
is the significance of the pattern shown in Figure 6?
