This month in Ecosphere, researchers from across the LTER network shared a collection of insights learned from 40-years of long-term research. The special feature, “Forecasting Earth’s Ecosystems with Long-Term Ecological Research”, includes papers that touch on themes of cascading effects, time lags, connectivity, state changes, and resilience. Several researchers from the Jornada, along with researchers from Central Arizona-Phoenix, Niwot Ridge, McMurdo Dry Valleys, Plum Island, and Santa Barbara Costal LTER sites, addressed the complex dynamics of connectivity and how it can influence ecosystem changes under changing human and environmental conditions.
