Cosmogenic Nuclide Burial Isochron Data for the Central City Gravel, Malta Gravel, and Lava Creek B Ash Locations: Classic Locations of Early to Middle Pleistocene Deposits, South Platte and Arkansas Rivers, Central Colorado, USA

This data release includes Al-26/Be-10 cosmogenic nuclide concentrations and burial isochron ages for three locations in central Colorado, USA, with preferred burial ages ranging from ~2 Ma to 600 ka, that provide constraints on geologic mapping and chronostratigraphic correlations of Pleistocene Co

Priority Faults for Improving Seismic Hazard Models in the Intermountain West Region

Abstract This data release includes a list of high-priority hazardous faults and associated spatial data (regional polygons and buffered fault traces) for the Intermountain West (IMW) region of the United States. These are the top five faults or regions of concern per IMW state, based on the 2025 (v

Data from: Betting on rains that do not come: Monsoon failure and leaf area overshoot relate to increased tree mortality from drought

Structural overshoots, where biomass is overallocated to tree leaf area compared to sapwood area, could result in lethal stress during droughts. Climate change may alter climatic cues that drive leaf area production, such as temperature and precipitation, as well as seasonal dynamics that underlie s

Associations Between Deer Browse and Aphid Colonization in a Long-Term Monitoring Study of Liguisticum porteri

Deer are prolific herbivores that, if left to increase exponentially, could decimate populations of plants and possibly other herbivores. Due to the rapidly increasing abundance of deer, this is a risk that is getting ever closer to becoming a reality. This phenomenon is a concern for herbivores tha

Coexistence in Burying Beetles: The Niche of Reproductive Temperatures

Coexistence among species can occur in a variety of ways through niche partitioning. Two major niche components for many organisms are temperature and soil moisture and variation in these may occur with habitat heterogeneity. Near Gothic, Colorado at the Rocky Mountain Biological Laboratory, there a

Local Adaptations and Fitness of Transplants in the Lewis Flax – Flax Rust Coevolutionary System

Disease progresses differently in varying environments. In coevolutionary interactions, species that interact frequently may adapt to their environment and to each other in a process called local adaptation. However, there may be trade-offs between adapting to the environment and to a coevolving par

The effects of cattle derived nutrients on growth rates of Arizona Tiger Salamander hatchlings in pastureland

Nitrogen is a critical element in biological systems, with its cycling increasingly influenced by human activities, particularly in agriculture. In Colorado, where 50% of land is used for agriculture, cattle grazing may impact the ecosystems of montane and subalpine ponds inhabited by Ambystoma mavo

Environmental Variation and Vegetative Composition in Beaver Engineered Ecosystems

The Colorado Rocky Mountains are uniquely heterogeneous, with beaver-engineered wetlands being sites with especially high relative biodiversity. Despite the large body of research available on the impacts of beaver activity on wetlands, the specific mechanisms of beaver activity that create high pla

The Effects of Temperature and N:P Ratios on Didymo Algae Growth

Didymosphenia geminata (didymo) is a species of algae that is native to North America, but has been producing unprecedented blooms during the last several decades. Climate change and nitrogen deposition are two hypothesized drivers of this phenomenon. The purpose of this research project is to bette

Stem and canopy growth analysis in Picea Engelmannii with UAVs and field measurements

Forests play a crucial role in mitigating climate change by sequestering large amounts of carbon dioxide from the atmosphere, so it is critical to evaluate their capacity to store carbon over time. Existing research on forest carbon sequestration relies on field methods that do not allow for samplin

Social Security: Do Individuals in Tight-Knit Social Groups Perceive Greater Security?

Antipredator behavior is influenced by many factors including group size. Group size effects are seen when animals in larger social groups allocate less time to antipredator vigilance while foraging, but group size alone does not capture the diversity and complexity of sociality and behavior. An ind

Indirect effect of black bears on sunflowers in nitrogen-polluted and pristine steppe

Both antagonistic and mutualistic types of interactions between species occur in most ecosystems, and these different types of interactions can contribute to indirect effects between species, such as trophic cascades. These interactions can be altered by humans, and one major way this is occurring i

Solitary bee genera differ in foraging activity timing and temperature; Evidence of a seasonal dietary shift in Hoplitis fulgida

Global warming, and exacerbated warming temperatures with humane activity, could impose novel conditions on the lives of many organisms. Of those, the behaviors and diets of solitary bees face adaptive stress as their optimal foraging conditions and preferred floral resources fluctuate. Trap nests m
