Sure.
The plant I was referring to is the willow, and there are many species. With warming temperatures they grow faster, and so they elevate the stems and leaves and those persist above the snow.
The second large change is a change in the seasonality of snow cover. Snow melting earlier in the season results in a higher albedo, a darker surface that absorbs more of the sun's solar energy. That ends up changing the depth of the active layer of permafrost, which can cause surface hydrology to change, that's the way streams and rivers and lakes are connected to each other on the frozen ground.
All these things are cumulative and seem to establish a positive feedback. The process of warming accelerates as that land surface changes. It's occurring over a very large area. And because it's changed only within the last decade, we really haven't anticipated the consequences. But, as I said, it's as dramatic as what's occurring in the Arctic Ocean.
