MISSION STATEMENT: The UC Natural Reserve System is a network of protected natural areas throughout California. Its 39 sites include more than 756,000 acres, making it the largest university-administered reserve system in the world. Most major state ecosystems are represented, from coastal tidepools to inland deserts, and lush wetlands to Sierra Nevada forests.

Soil Water Content at MMWD

Peter Hartsough
These data were collected using Decagon (Meter) GS1 sensors at two different depths, 30cm and 60cm. Data were collected hourly and these are mean values at the three different sites.

A microbial survey of the International Space Station (ISS)

Jonathan Eisen, David Coil & Jenna Lang
Background Modern advances in sequencing technology have enabled the census of microbial members of many natural ecosystems. Recently, attention is increasingly being paid to the microbial residents of human-made, built ecosystems, both private (homes) and public (subways, office buildings, and hospitals). Here, we report results of the characterization of the microbial ecology of a singular built environment, the International Space Station (ISS). This ISS sampling involved the collection and microbial analysis (via 16S rDNA PCR)...

Caltrans PEMS highway sensor average flows by occupancy

Clark Fitzgerald & Michael Zhang
This data summarizes average vehicle flow as a function of occupancy for traffic sensor data available from CalTrans Performance Management System (PEMS). It's useful because it shows the behavior of traffic in congested regimes, without requiring the preprocessing of several hundred GB of the raw data. Open the pdf files to see what this data looks like.

Heterotrophic N2-fixation contributes to nitrogen economy of a common wetland sedge, Schoenoplectus californicus

Eliska Rejmankova, Dagmara Sirova, Stephanie Castle, Jiri Barta & Heather Carpenter
These data sets document environmental characteristics of sampling locations of Schoenoplectus californicus, california bulrush, throughout its range in the Americas. In addition, the data on nif gene in rhizomes and roots of Schoenoplectus are provided.

Habitat preference and species interactions of the desert woodrat (Neotoma lepida) in the Mojave Desert

Becca Cosmero, Emily Fieberling, Katherine Marlin, Ricardo Ruiz, & Lara Volski
Ecosystem engineers often have cascading impacts on the ecosystems in which they occur. Understanding the factors that contribute to their habitat selection can provide valuable information on how ecosystems function. Our study investigates the habitat distribution of desert woodrats (Neotoma lepida) in the Eastern Mojave Desert. We show that there is a difference in desert woodrat abundance among habitats, and found that specific aspects of these environments are associated with woodrats. These aspects include grass...

Vibrational Neutron Scattering Spectra for Undoped and Doped P3HT

Thomas Harrelson, Jun Li & Adam Moule
Doped semiconducting polymers have garnered vast research interest in photovoltaic, transistor, thermoelectric, and sensor applications. P3HT is a canonical semiconducting polymer that self-assembles into a mixture of crystalline and amorphous domains. Doping P3HT can increase the observed conductivity by several orders of magnitude. The vibrations of the polymer are sensitive to the local morphology of the film, and the morphology of the film changes upon doping. Vibrational neutron spectroscopy is a method for identifying vibrational...

Regional and disease-related differences in properties of the equine temporomandibular joint disc

Derek Cissell
Temporomandibular joint (TMJ) disorders are increasingly recognized in animals. The articular disc plays a major role in TMJ disorders in people, but its role in the pathogenesis of TMJ disease in animals is not well understood. This study characterizes properties of the equine TMJ disc, including regional variation within discs as well as differences in properties associated with naturally-occurring TMJ osteoarthritis.

Defining hydrogel properties to instruct lineage- and cell-specific mesenchymal differentiation

Kent Leach
The maintenance and direction of stem cell lineage after implantation remains challenging for clinical translation. Aggregation and encapsulation into instructive biomaterials after preconditioning can bolster retention of differentiated phenotypes. Since these procedures do not depend on cell type or lineage, we hypothesized we could use a common, tunable platform to engineer formulations that retain and enhance multiple lineages from different cell populations. To test this, we varied alginate stiffness and adhesive ligand content, then encapsulated...

Formica ant and Cinara aphid mutualisms on limber pines (Pinus flexilis)

Charles Chen, Lori Liu &
Ant-aphid mutualisms play important ecological roles in many ecosystems. While Formica ants are well studied model organisms, pine-specialist Cinara aphids remain understudied. Moreover, there is little research on ant-aphid mutualism in subalpine ecosystems. We investigated multiple species of Formica ants and their mutualistic interactions with Cinara aphids on the limber pine Pinus flexilis in a subalpine ecosystem. Cinara apini colonies were found tended to by silver, black, and red Formica ants, and they occupy older...

An ancient forest on the move: Range shifts in bristlecone pines

Angela Delos Santos, Katherine Pratt, Grace Rosburg-Francot, Linnea Schaefer & George Sidarous
Recent changes in global climate are causing many species to shift their ranges towards higher elevations. The rate at which species can shift their ranges may determine whether or not they will be able to persist in light of such rapid environmental change. In this study, we examined the effect of elevation on recruitment, mortality, and intraspecific competition in Great Basin bristlecone pines (Pinus longaeva, BC), a long-lived subalpine species whose upper limit is often...

Alpine wet meadows: soil properties’ effect on plant diversity

Madeline Castro, Fidel Machado-Perez & Rebecca Raven
Alpine ecosystems are a harsh environment with little nutrients and the abiotic effect that the soil has on the plant community is relatively unknown. The focus of this study is to illuminate the role that soils play in the plant diversity of alpine wet meadows. In doing so we investigated the function of clay and root content, organic matter, pH and soil moisture in determining plant diversity in three meadows in the White Mountains, California....
