Herbarium-Derived Phenological Data in North America

We present infrastructure for developing large-scale and long-term phenological datasets across multiple herbaria, as well as a sample dataset that has been acquired from the digital archives of 440 distinct herbaria across North America and further processed to evaluate phenological status. This da

Manual soil CO2 flux, temperature and water content measurements from the Snodgrass and Copper Creek elevation transect

The manual_soil_measurements_2022_2023.csv data set contains all of the manually measured soil CO 2 efflux, volumetric water content and soil temperature during field visits to the Rocky Mountain Biological Laboratory. In 2022, 16 PVC collars were installed at each site, there are two sets of collar

SAIL-Net Raw and Post Corrected POPS Data Fall 2021 - Summer 2023

SAIL-Net is a DOE funded project in the East River Watershed near Crested Butte, Colorado with the goal of advancing our understanding of aerosol-cloud interactions in complex, mountainous regions. Through the deployment of a network of six low cost microphysics nodes in Fall 2021 in the same domain

The Effects of Climate-Driven Changes in Co-flowering between <i>Linum lewisii</i> and <i>Potentilla pulcherrima</i> on Pollinator Services

Anthropogenic climate change is affecting many ecosystems. Changes in the melting of snowpack have altered flowering phenology in subalpine meadows. The subalpine meadows at the Rocky Mountain Biological Laboratory in Gothic, Colorado are experiencing shifts in co-flowering patterns. Two flowers, Li

Effects of Ant Presence on Nicrophorus investigator’s Reproductive Success

Burying beetles require carrion in order to successfully reproduce and they compete with vertebrate scavengers, other burying beetles, ants, flies, fungi, and microbes for this ephemeral resource. Burying beetles have mechanisms to combat competition from fly eggs, fungi, and microbes, but interacti

Comparing detritus breakdown rates with and without detritivores in subalpine ponds with different hydroperiods

It is widely accepted that in stream systems, detritivores accelerate the breakdown of detritus that has been “conditioned” by microbial decomposers. By accelerating the breakdown of dead plant material, detritivores release nutrients and smaller food particles that are used by downstream plants and

Effect of blood parasites on secondary sexual characteristics and morphology in mountain white-crowned sparrows

Blood parasites affect numerous species of birds across the world and can cause serious population declines. Haemosporidian blood parasites in Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) are known to affect certain behavioral and morphological characteristics of hosts, includin

An integrative study of marmot responses to ecotourism

Human disturbance in the form of ecotourism alters behavior many species and may impact fitness but few studies take an integrative approach to quantify impact in various ways to test for variation in physiological, behavioral, and consequential life history and demographic traits. We extended a pre

The impacts of early snowmelt and summer precipitation on the physiology and leaf morphology of <i>Ipomopsis aggregata</i>

Climate change is occurring, and the effects will be visible all over the planet. In a subalpine ecosystem, earlier snowmelt and changes in summer precipitation are predicted to occur due to an increase in air temperature. During the summertime, this variation may lead to changes in traits, a proces

Evaluating Critical Thermal Tolerances of Solitary Bees

Climate change is predicted to impact pollinators through both direct and indirect mechanisms: by altering physiological stress through warming temperatures and by changing species interactions through the altered phenology and abundance of food sources and competitors. While research has been done

Characterizing nectar content in wet and dry subalpine meadows during an extreme summer drought

Pollinating bees visit flowers in order to forage for nectar and pollen, their major sources of nutrition. The plant communities that a bee interacts with vary across time and space, as different flower species dominate different habitats. One key driver of the spatial variation in plant communities

More social female yellow-bellied marmots have enhanced summer survival

For many animals, group living is an effective strategy to mitigate predation risk and ensure survival. However, in yellow-bellied marmots (Marmota flaviventer), increased sociality is associated with lower female reproductive success, decreased female longevity, and increased over-winter mortality

The Effect of Climate Change on Plant Communities in the Rocky Mountains: How floral traits differ along an elevational gradient and in reciprocally transplanted communities

Alpine zones are characterized by climatic conditions that can vary over short vertical distances. Therefore, elevational gradients have been used to study how changes in climate can influence plant form, function, and diversity. In my study, I examined floral traits in native communities along an e
