Climate change, including glacial cooling and interglacial warming, can influence dietary behavior, potentially affecting prey preferences and the degree of carcass utilization. In this study, we investigated the dietary behavior of Smilodon in Florida during the Pleistocene using dental microwear texture analysis (DMTA). We used DMTA metrics, comp...

Climate change, including glacial cooling and interglacial warming can influence dietary behavior, potentially including prey preferences and the degree of carcass utilization. In Florida during the Pleistocene, the diet of Smilodon gracilis, a more gracile saber-toothed cat, shifted prey-preference depending on whether it lived during a glacial or...

The Santa Susana Field Laboratory (SSFL) was a nuclear reactor development, rocket, and missile testing facility built ~48 km (30 miles) northwest of downtown Los Angeles in Simi Valley, CA. For two weeks in July of 1959, highly radioactive material was potentially emitted into the atmosphere following a secret nuclear incident. The partial meltdow...

Los Angeles Department of Water and Power (LADWP) began implementing a riparian restoration plan in 1993, as a response to the degradation of McGee Creek in Owens Valley and Mono County, California ( Figure 1a ). Natural channel morphology (changes) and anthropogenic influences from overgrazing of cattle and water management practices (agricultural...

The San Joaquin River in Central California has undergone significant morphological changes due to anthropogenic influences, particularly the construction of dams such as the Friant Dam. These changes have disrupted natural water flow, sediment transport, and habitat availability, leading to critical ecological impacts, including the near extinctio...

Innovative interdisciplinary research is critical to understanding the varied and relatively well-preserved environments that are National Preserves. Blueprint Earth is conducting interdisciplinary research in a 1km² area within the Cane Spring system in the Mojave National Preserve, a site chosen for its relative inaccessibility to the general pub...

Identifying and understanding areas of great biodiversity and the processes and conditions that support them is essential for environmental research and conservation within an interdisciplinary geosciences context. Blueprint Earth is currently mapping spatial patterns of biodiversity and endemism within a hydrogeologically complex 1 km² section of...

The immediate motivation for this study was to provide an insight in the distribution of desert vegetation in the Mojave Desert. Exotic (non-native) vegetation are igniting rare wildfires in the Mojave as a result of climate change. Understanding the desert sunflower’s distribution can be an indication on where and why vegetation thrive in the Moja...
