The hills near Missoula, Montana, are changing, native grasses and other plants increasingly squeezed out by nonnative plants. Knapweed, cinquefoil, and other weeds aren’t only changing the look of this ecosystem but its very structure. As ecologist Dean Pearson’s research has shown, however, some species are benefitting from the changed habitat in unexpected ways. You just have to look closely to see them.

This is a dorsal view of a female spider. In insects and spiders, the heart is a dorsal tube, so in a spider with a transparent exoskeleton like this one, we can see the heart pumping.
Thanks to William Eberhard for identifying the species and telling me this story about the video, which I taped under a dissecting microscope.
Español:
Este es una vista dorsal de una hembra. En los insectos y las arañas, el corazón es un tubo dorsal, y por eso en una araña con el exoesqueleto transparente como esta se puede ver el corazón latiendo.
Gracias a William Eberhard por la identificación de la especie y por contarme esta historia sobre el video que tomé bajo un estereoscopio.
