Just because something isn’t easy to see doesn’t mean it can’t have significant impacts on our environment — and our well-being. Dr. Alexandra Ponette-González, a biophysical geographer and associate professor in UNT’s Department of Geography and the Environment, has been bringing the invisible to light for years through her research that examines human-atmosphere-biosphere interactions, including projects that have investigated the use of trees as natural urban air filters, the influence of drought-induced dust on nutrient and pollutant inputs to ecosystems in Texas, and the accumulation of black carbon on bird feathers.

In this episode, we discuss:

● The importance of biophysical geography

● Ponette-González’s research, which includes examining the effects of global environmental change on atmospheric deposition (which consists of materials that enter ecosystems from the atmosphere), as well as terrestrial ecosystems spanning tropical forests to urban areas

● How she sees science having an impact in these areas moving forward.
