Re-Evaluating Springtime as Southern Arizona's Dust Season. [PDF]

Geohealth
Abstract The existing literature largely identifies spring as Arizona's predominant dust season, when synoptic‐scale dust events are most frequent and “Fine Soil” measurements from the IMPROVE (Interagency Monitoring of Protected Visual Environments) network reach a yearly maximum.

Grassification and Fast-Evolving Fire Connectivity and Risk in the Sonoran Desert, United States

Frontiers in Ecology and Evolution, 2021
In the southwestern United States, non-native grass invasions have increased wildfire occurrence in deserts and the likelihood of fire spread to and from other biomes with disparate fire regimes. The elevational transition between desertscrub and montane
