Daily water stable isotopes, transpiration, and matrix potential data for an aspen and engelmann stand in the East River Watershed
We provide daily stable isotope (2H & 18O) ratios in soil water and xylem (plant stem) water, as well as the sap flow (transpiration) and the soil's matric potential at a forested site near Gothic, Colorado, in the East River catchment. We measured the stable isotopic composition of the transpi
Potentilla demographic and environmental data for Rainbow Meadows, Elk Meadows, and Cabin Clearing, 2018 - 2020.
To understand parent-hybrid dynamics in cinquefoil (Potentilla) species in the Colorado Rocky Mountains, I am estimating environmental overlap among parents and hybrids, interbreeding among parents and hybrids, and hybrid population growth in multiple natural populations at NWT and (not included her
Potentilla flowering phenology for Cabin Clearing, Elk Meadows and Rainbow Meadows, 2019.
To understand parent-hybrid dynamics in cinquefoil (Potentilla) species in the Colorado Rocky Mountains, I am estimating environmental overlap among parents and hybrids, interbreeding among parents and hybrids, and hybrid population growth in multiple natural populations at NWT and (not included her
Facilitation strength across environmental and beneficiary trait gradients in stream communities
Ecosystem engineers modify habitats in ways that facilitate other community members by ameliorating harsh conditions. The strength of such facilitation is predicted to be influenced by both beneficiary traits and abiotic context. One key trait of animals that could control the strength of facilitati

Transgenerational and within-generation plasticity in response to climate change: insights from a manipulative field experiment across an elevational gradient
Parental environmental effects-or transgenerational plasticity-can influence an individual's phenotype or fitness yet remain underexplored in the context of global change. Using the perennial self-pollinating plant Boechera stricta, we explored the effects of climate change on transgenerational and
Traditional plant functional groups explain variation in economic but not size related traits across the tundra biome
Using ecological stoichiometry to understand and predict infectious diseases
A key characteristic of host–parasite interactions is the theft of host nutrients by the parasite, yet we lack a general framework for understanding and predicting the interplay of host and parasite nutrition that applies across biological levels of organization. The elemental nutrients (C, N, P, Fe
Direct and indirect effects of episodic frost on plants growth and reproduction in subalpine wildflowers
Climate Warming Drives Local Extinction in a Subalpine Meadow
Transient LTRE analysis reveals the demographic and trait-mediated processes that buffer population growth
Adriana A. Maldonado- Temporal variation in environmental conditions affects population growth directly via its impact Chaparro,1,2,3* Daniel T. on vital rates, and indirectly through induced variation in demographic structure and phenotypic Blumstein,1,4 Kenneth B.

Plant dominance in a subalpine montane meadow: biotic vs. abiotic controls of subordinate diversity within and across sites
Background. Understanding the underlying factors that determine the relative abun- dance of plant species is critical to predict both biodiversity and ecosystem function. Biotic and abiotic factors can shape the distribution and the relative abundance of species across natural communities, greatly i
Heritable plant phenotypes track light and herbivory levels at fine spatial scales
Organismal phenotypes often co-vary with environmental variables across broad geographic ranges. Less is known about the extent to which phenotypes match local conditions when multiple biotic and abiotic stressors vary at fine spatial scales. Bittercress (Brassicaceae: Cardamine cordifolia), a peren
A molecular investigation of soil organic carbon composition across a subalpine catchment
The dynamics of soil organic carbon (SOC) storage and turnover are a critical component of the global carbon cycle. Mechanistic models seeking to represent these complex dynamics require detailed SOC compositions, which are currently difficult to characterize quantitatively. Here, we address this ch
Consistent shifts in pollinator-relevant floral coloration along a Rocky Mountain elevation gradient
Microenvironment and functional-trait context dependence predict plant community dynamics
Abstract Predicting the structure and dynamics of communities is difficult. Approaches linking functional traits to niche boundaries, species co‐occurrence and demography are promising, but have so far had limited success. We hypothesized that predictability in community ecology could be improved by
Plant functional trait change across a warming tundra biome
Biome-wide relationships between temperature, moisture and seven key plant functional traits across the tundra and over time show that community height increased with warming across all sites, whereas other traits lagged behind predicted rates of change.
