Datasets uploaded after Feb 22, 2024 have the sensor labels corrected for all dates going back to install

This child item contains the raw acoustic Doppler velocity profiler (ADCP) measurements collected by U.S. Geological Survey (USGS) hydrographers at each site to validate Image and Radar velocimetry results. The discharge measurements were collected as part of routine and standard streamflow gaging d

Recent climate change has contributed to large-scale tree mortality across forested regions in Colorado. As forest health declines, concern for associated terrestrial biogeochemical and hydrologic shifts is mounting. These shifts are related to reduced tree canopy cover, cessation of belowground rhi

Abstract Body condition is an important life history challenge that directly impacts individual fitness and is particularly important for hibernating animals, whose maintenance of adequate body fat and mass is essential for survival. It is well documented that symbiotic microorganisms play a vital r

Functional trait diversity within species assemblages ultimately determines whether or not ecosystem processes are sensitive to shifts in relative abundances or species composition. For example, trait variation suggests detritivores process detritus at different rates and make different relative con

Climate change poses a unique problem for sessile species because individuals are unable to move to track their optimal habitat. Instead, population turnover governed by population processes must occur in order for the species distribution to change. Current methods to predict current and future spe

This study analyzed how soil moisture and snow depth correlates with leaf traits of Ipomopsis aggregata across and within populations in the Crested Butte and Gothic, Colorado area. Earlier snowmelt due to global warming is lessening soil moisture in early summer in the Rocky Mountains and potential

High altitude regions are likely to be highly affected by climate change. Pollinators such as bees in these regions may have to change life history traits to survive. Because eusociality is associated with reduced mortality and increased resilience to resource variation, primitively eusocial bees ma

Pollinators play an important role within a variety of ecosystems but are experiencing declines. In recent years, climate change has been affecting the mutualistic relationship between these organisms and the corresponding plants they interact with. It is important to closely study interactions such

The tiger salamander is the top predator of the benthic invertebrate in the ponds at the Mexican Cut Nature Preserve, and hence, one of the main influential factors on the benthic invertebrate community structure. Recent phenomena observed at the MCP, like earlier snowmelt dates of some of the ponds

Arizona tiger salamanders (Ambystoma mavortium nebulosum) can thrive in a large variety of environments including high elevation ecosystems where climate change conditions are most drastic. Accurate biophysical models of the water loss and operative temperature for A. m. nebulosum can be used as too
