Your observation about the unique mix of species at the boundary – with both woodland and grassland species coexisting in that narrow strip – is particularly fascinating. It reminds me of my early research in the Amazon, where we found similar patterns at forest fragment edges, though at a much different scale. b. Your description of the increased bird diversity in these transition zones perfectly illustrates what we discussed during your graduate studies about the "edge effect" phenomenon. c. I'm especially intrigued by your note about the butterfly species that seem to thrive exclusively in these edge zones. This could be a valuable contribution to our understanding of how habitat boundaries can create their own distinct ecological niches. Perhaps we could collaborate on a paper about this?
