Time-lapse imagery was collected using an automated RGB camera mounted on a pole at the base of the northeast-facing hillslope at the Lower Montane site in the East River Watershed, Colorado. The imagery was intended to support a better understanding of plant dynamics and their controls during the g

Snowmelt is a critical biogeochemical period that accounts for large nitrogen (N) export events from high-elevation watersheds. Soil microbial populations bloom and immobilize N during snowmelt, yet the population size crashes in spring, which releases a pulse of soil N. We sought to discover the N

This data package presents snow depths data from distributed temperature probes at 18 locations near Snodgrass catchment, Colorado. These data show that snow melt-out dates are approximately one or two weeks later under evergreen forests compared to other vegetation types even at the same elevation.

Drought is changing the American Mountain West at unprecedented rates with unknown consequences to soil microbiome composition and function. As a part of LBNL Watershed Science Focus Area (SFA), we investigated shifts in microbial community and transcriptional activity on a subalpine conifer-meadow

The movement of water through a plant’s parts, out its stomata, and into the atmosphere begins with moisture available in the soil. Soil water availability is determined by rates of evaporation from the Earth’s surface, which increases with temperature. Alteration of water content determines the soi

Anthropogenic climate change is altering environments, which in turn has the potential to influence plant traits (through phenotypic plasticity) and natural selection. The effect of changing climate on the strength and direction of selection remains unresolved. In this study we quantified the plasti

Ant-aphid mutualisms are keystone interactions that, if altered, have the potential to cause cascading, multitrophic effects on local arthropod and plant communities. In our study system, the flowering stalks of Ligusticum. porteri (Apiaceae) are colonized by the aphid Aphis asclepiadis, which relie

Most living organic material goes through the detrital pathway. Detritovores are incredibly important in ecosystems for the recycling of nutrients and energy. This project explores the inter- and intraspecies relationships between two co-dominant detritovores that inhabit the high-elevation rocky mo

Climate change will increasingly impact ecosystem functioning due to shifts in species distributions as they seek their optimal climatic conditions. Plants rely on phenotypic plasticity of leaf traits to tolerate a change in their climate. Plant leaf traits also affect the carbon cycle of the local

The golden-mantled ground squirrel (Callospermophilus lateralis) was first classified as an asocial sciurid in 1983, and little follow-up research has effectively challenged this notion since the early literature. The only recognized social behavior in the species has been documented between young l

Carrion plays an important role in maintaining ecosystems and providing resources for different forms of life, returning key nutrients to the environment and serving as a food source for animals. While vertebrates who consume carrion are well studied, invertebrates are not as well studied, primarily

Plant-pollinator networks are useful tools for understanding species interactions and biodiversity. The structure of interactions within plant-pollinator networks have provided insight into the potential stability and persistence of ecological communities. Current studies of plant- pollinator networ

Plant-pollinator interactions rely on the exchange of nectar and pollen for pollination services. Nectar traits can be influenced by changes in abiotic factors such as water availability, and such variation may in turn influence interactions with pollinators. This experiment investigated how the nec

Golden-mantled ground squirrels (Spermophilus lateralis) and yellow-bellied marmots (Marmota flaviventris) can both be found in abundance at high elevation meadows in the Rocky Mountains. Though different in behavior, both species inhabit and utilize the open meadows of Gothic in very similar ways.
