Restoring monarch butterfly habitat in the Midwestern US: 'all hands on deck'

The eastern migratory population of monarch butterflies (Danaus plexippus plexippus) has declined by >80% within the last two decades. One possible cause of this decline is the loss of >= 1.3 billion stems of milkweed (Asclepias spp.), which monarchs

Operationalizing the telecoupling framework for migratory species using the spatial subsidies approach to examine ecosystem services provided by Mexican free-tailed bats

Autor: López-Hoffman, Laura, Diffendorfer, Jay, Wiederholt, Ruscena, Bagstad, Kenneth J., Thogmartin, Wayne E., McCracken, Gary, Medellin, Rodrigo L., Russell, Amy, Semmens, Darius J.

Drivers of environmental change in one location can have profound effects on ecosystem services and human well-being in distant locations, often across international borders. The telecoupling provides a conceptual framework for describing these inter
