Invasive plants and plant pollinator networks

We have a new article revisiting the topic of my PhD thesis, but with a twist. Invasive plants effects on network modularity. Back then I already explored a bit the effects of invasive plants on the modular structure of the plant-pollinator community, but I never published any result, among other things because I didn’t understand well what I was doing. That’s why when Matthias asked me to join his paper addressing this question with a bigger dataset I was very happy to give it a second try.

Now (6 years later!) I understand two key things way better. First, that invasive plants have different roles in the network than natives, not because they are not native, but because of its different characteristics (i.e. very abundant and generalized). Second, that it is more interesting to understand how the roles that different species play within the network change, than how the overall network structure change, mainly because very different networks can present very similar structures (i.e. nested and modular). I think we nicely present this two points in the paper. See the figure below, and read the paper if you a curious about knowing more.
