iBioBlitz

During this bio blitz, one of my own observed organisms that I was able to track on the phylogenetic tree was Paper Birch (Betula papyrifera).
On the phylogenetic tree, this species can be found under flowering plants, further extending into Pentapetae, then into Fabids, Fagales and finally after its most recent common ancestor the Bog Birch.
Paper Birch is considered a pioneer species, which essentially means that it is one of the first to grow in the wake of a forest’s destruction (typically by fire). This is because their seeds are incredibly light, meaning they are easily carried by the wind to barren or burned areas where they can germinate and populate quickly.
For the project overall, one adaptation that all of the observations had in common was pod structures which contain the seeds. All of the species were skewed between coniferous and deciduous trees, so although the structures themselves (cones vs nuts) are different, they all have very similar caveats for reproduction.
