A series of field measurements of surface water velocity derived from video and Doppler velocity radar collected by small unoccupied aircraft systems (sUAS) and portable sensors were collected at seven locations in Colorado, USA, during the summer of 2023. The measurements were utilized to compute s

This is an examination the late Paleozoic and Early Mesozoic structural history of the Uncompahgre front and the Paradox Basin.

Climate change is increasing temperatures globally including aquatic habitats like rivers, directly affecting the biology of many invertebrate species. In freshwater ecosystems, snow melt drives rivers in the Rocky Mountains of Colorado. Increasing river temperatures can result in increasing metabol

Ecotourism promotes conservation efforts while also allowing for low impact observation of

The question of thermoregulation in plants is increasingly important in a rapidly changing climate. Plants have long been considered poikilotherms, where internal temperatures are decided by the external environment. However, observations show that plants have some ability to thermoregulate. If plan

High-elevation ecosystems are experiencing rapid warming and severe impact of global climate change. The Arizona Tiger Salamander (Ambystoma mavortium nebulosum) occurs in high elevation ponds in the West Elk Mountains of Colorado and offers a compelling system to test context-dependent responses to

Quaking aspen (Populus tremuloides) trees are a foundation species that is widely distributed across all North America. Since the early 2000s, high levels of mortality have been observed in these forests. In recent decades, many quaking aspen forests have been experiencing high mortality rates. This

In 2020, wildfires burned more acreage in the United States than in the past twenty-one years.1 Boreal wildfires are the cause of ten percent of all annual atmospheric soot in the Northern Hemisphere, which is alarming because soot is detrimental to both human health and environmental health. Some o

Native species are threatened by the introduction of non-native and invasive organisms.

While plant-pollinator networks are salient markers of biodiversity, their mechanisms remain poorly understood. One theory describing pollination interactions is the Neutral Theory of Biodiversity, which asserts that plant-pollinator interactions are neutral, random processes based on species’ abund

As ecosystems continue to change, the ability to find high-quality habitats is becoming a valuable skill. Caddisflies are often found in pond environments with a variety of habitat qualities, such as food (detritus) quality. Asynarchus nigriculus, being highly mobile and having a unique dietary need

Abstract. Soil thickness plays a central role in the interactions between vegetation, soils, and topography, where it controls the retention and release of water, carbon, nitrogen, and metals. However, mapping soil thickness, here defined as the mobile regolith layer, at high spatial resolution rema

vironmental studies will be used in making decisions about the design and location of mine and mill facilities. It will also provide a baseline for measuring and mitigat - ing effects of subsequent mining operations. Closely connected to the environmental assessment are studies of socioeconomic impa
