Fluctuating flowering patterns affect an environments floral abundance, impacting the spatial structure of nectar and pollen resources, ultimately influencing floral visitor foraging behavior. We examined the effect of reducing floral resources on floral visitors of Monardella odoratissima, commonly known as the mountain coyote mint. Isolated patches of M. odoratissima were created by removing all surrounding resources, in order to test its effect on floral visitor communities. Exploring how the resource-richness of a habitat affects this...

Drylands are prone to desertification as human disturbances degrade desert ecosystems and limit their capacity to bio-produce. Biological soil crusts, a specialized community of lichen and cyanobacteria, are particularly vulnerable to these disturbances. To gauge the effects of anthropogenic disturbance on soil particle size and soil crust growth, Collema, a widely-distributed genus of soil lichen, was used as an indicator of overall ecosystem health. We used the visual percent cover method in four “low disturbance”...

Road disturbance can facilitate the establishment and growth of invasive plant species and herbivorous insects in adjacent ecosystems. The hydrological and atmospheric impacts of roads are especially important to understand in arid desert environments that are highly sensitive to water stress and dust pollution. In this study, we looked at how impacts of road disturbance change among different road types within the Mojave Desert. Specifically, we observed how three types of roads (paved road, dirt...

Streams and rivers represent less than 0.0001% of the planet's water, but are support up to 10% of its biological diversity and are fundamental to human life. As sources of drinking water, transportation, recreation, and energy, streams are both highly valuable and highly vulnerable to us. Humans have obvious imperative to protect stream ecosystems, but many effects are likely to be unintentional and unseen, incidental to our existing in a place. We sampled stream macroinvertebrate...

Disturbance often increases local-scale (α) diversity by suppressing dominant competitors. However, widespread disturbances may also reduce biotic heterogeneity (β diversity) by making the identities and abundances of species more similar among patches. Landscape-scale (γ) diversity may also decline if disturbance-sensitive species are lost. California’s vernal pool plant communities are species-rich due in part to two scales of β diversity: (1) within pools, as species composition changes with depth (referred to here as vertical β diversity),...

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. The reserves also serve as a gateway to more than a million acres of public lands. Founded in 1965 to provide undisturbed...

Synthesis and metabolism of steroids is highly interconnected within a tissue. The initial objective of these studies was to evaluate the influence of estrogens on the synthesis and metabolism of other steroids in the testis and other tissues. The aromatase inhibitor, letrozole, was used to inhibit testicular estrogen synthesis. Littermates from five different litters (potentially six boars from one litter) provided the testis, prostate, and liver tissues but only four boars (one from each of...

This dataset contains data from figures and model code used to generate figures in the paper "Influence of Relative Humidity on the Heterogeneous Oxidation of Secondary Organic Aerosol" by Li et al., published in Atmospheric Chemistry and Physics. A description of the work follows below. See read me files for details. Secondary organic aerosol (SOA) is a complex mixture of hundreds of semi‑volatile to extremely low‑volatility organic compounds that are chemically processed in the atmosphere,...

This database contains images of 258 individual strawberries with dark background (a setting typically encountered during post-harvest operations). For each strawberry, six images are provided: 1) a color image of the entire strawberry; 2) a color image containing only the calyx of the strawberry; 3) a color image containing only the flesh of the strawberry; 4) a binary image of the entire strawberry; 5) a binary image of the calyx, and 6) a binary image...
