Forage Resources in Warming and Removal Plots, Almont, CO, 2019
This is data collected to explore the impacts of warming and dominant species removal on the quantity and quality of plants for cattle foraging. The data were collected from the Colorado low elevation site (Almont) of the Warming and Removal in Mountains experiment which examines the direct and indi

Herbarium specimens reliably track plant phenological responses to climate change in understudied montane biomes
File: Peng_et_al._20206.zip Description: There are three folders here. The Data folder contains the raw specimen phenology data and the RMBL phenology data. The Analyses folder contains the data frames used to build the linear mixed-effects models. The Codes folder contains R codes

Mountain Basin Controls on the Snow-to-Streamflow Signal: An AIC-Weighted Multiple Linear Regression Framework
A regression-based analysis quantifies how basin characteristics modulate the snow-to-streamflow signal. First, we use the ERA5-Land reanalysis gridded product (European Centre for Medium Range Weather Forecasts reanalysis 5 -Land component) for 4,655 hydrologic unit code - 10 (HUC10) mountain basin
Responses to climate change – insights and limitations from herbaceous plant model species
Comparative life-cycle analyses reveal interacting climatic and biotic drivers of population responses to climate change
Responses of natural populations to climate change are driven by how multiple climatic and biotic factors affect survival and reproduction, and ultimately shape population dynamics. Yet, despite substantial progress in synthesizing the sensitivity of populations to climatic variation, comparative st
Running on Empty: Climate Change and the Future of the Colorado River Basin
Amid growing pressures from climate change and population growth, water availability in the Colorado River Basin is declining while demand continues to rise. At the Water Dialogue Lab at the University of California, Riverside (UCR), Prof Mehdi Nemati and his colleagues, Dr Daniel Crespo, Prof Ariel
Warming disrupts plant–fungal endophyte symbiosis more severely in leaves than roots
Disruptions to functionally important symbionts with global change will negatively impact plant fitness, with broader consequences for species' abundances, distribution, and community composition. Fungal endophytes that live inside plant leaves and roots could potentially mitigate plant heat stress
Adaptation and gene flow are insufficient to rescue a montane plant under climate change
Climate change increasingly drives local population dynamics, shifts geographic distributions, and threatens persistence. Gene flow and rapid adaptation could rescue declining populations yet are seldom integrated into forecasts. We modeled eco-evolutionary dynamics under preindustrial, contemporary
Predicting the contribution of single trait evolution to rescuing a plant population from demographic impacts of climate change
Evolutionary adaptation can allow a population to persist in the face of a new environmental challenge. With many populations now threatened by environmental change, it is important to understand whether this process of evolutionary rescue is feasible under natural conditions, yet work on this topic
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
A habitat‐centered framework for wildlife climate change vulnerability assessments: Application to Gunnison sage‐grouse
AbstractThe persistence of threatened wildlife species depends on successful conservation and restoration of habitats, but climate change and other stressors make these tasks increasingly challenging. Applying climate change vulnerability analyses to contemporary wildlife management can be difficult
Changes in insect population dynamics due to climate change
Abstract Climate change can modify the population dynamics of insects. In this instance, “climate” encompasses temperature and precipitation patterns, including dry season or snow cover duration and timing. Also included are changes in both climate means and variances. Insect declines in response to
The buzz around biodiversity decline: Detecting pollinator shifts using a systematic review
Climate and land use change are two of the largest drivers of worldwide biodiversity loss, but detecting drivers of insect decline is more complex. Online data sources can elucidate such responses while identifying systematic data gaps. Using a systematic review, we found 119 studies that document b
Exploring the impact of climate change on soil carbon storage in montane meadows
The excess of greenhouse gasses like carbon dioxide in the atmosphere urgently calls for a deeper understanding of existing natural mechanisms for carbon sequestration. Montane meadows act as a critical natural carbon sink, often having the capacity to store much more carbon in their soils than surr
Tracking changes in montane butterfly populations through the lens of climate change
Effects of a caddisfly range shift on competition and facilitation in high elevation ponds
As temperatures warm, the climate crisis is having a significant influence on species all across the world and altering their distributions. Colorado's high elevation ponds have recently observed a species range shift, traveling to higher altitudes than they have previously inhabited. The Mexican Cu
The timing of reproduction is responding plastically, not genetically, to climate change in yellow-bellied marmots (Marmota flaviventer)
With global climates changing rapidly, animals must adapt to new environmental conditions with altered weather and phenology. The key to adapting to these new conditions is adjusting the timing of reproduction to maximize fitness. Using a long-term dataset on a wild population of yellow-bellied marm
Harnessing the power of algae: new, greener fuel cells move step closer to reality
Harnessing the power of algae: new, greener fuel cells move step closer to reality A new design of algae-powered fuel cells that is five times more efficient than existing plant and algal models, as well as being potentially more cost-effective to produce and practical to use, has been developed by
