Data from: The effect of shrub cover on conifer water-use patterns, growth, and response to climate change in the southern Sierra Nevada
<p>As wildfire increases in size and severity, large areas of forest are undergoing substantial increases in shrub cover. In forests where water is the limiting resource, the paritioning of soil water between shrubs and trees may determine how shrubs affect tree growth and water-stress. We analyzed hydrogen and oxygen isotopes in the xylem water for two conifer species and two shrub species to assess how shrub cover affects the water-uptake patterns of conifers in the southern Sierra Nevada. Further, we analyzed tree growth and stable carbon isotopes in tree rings to assess how shrub cover affects tree growth, intrinsic water-use efficiency and response to climate change.</p>

How surface rock cover affects water and nutrient availability of Sonoran Desert annual plants -- Honors Thesis
Water and nutrient availability are the primary and secondary drivers of net primary productivity (NPP) in arid ecosystems. Although precipitation regulates water inputs, soil properties influence water availability for plant growth. Aridland soils are often covered with surface rocks, which can increase or decrease water availability by modifying evaporation, infiltration, light levels, and temperature. Due to the complexity of these direct and indirect mechanisms, the relationship between rock cover and NPP is not well understood. In this research we explore the relationship between rock cover, soil nutrient availability, and aboveground growth of desert annual plants over four years across a long-term nutrient enrichment experiment in the Sonoran Desert. We surveyed surface rock cover at fifteen sites in central Arizona that have been fertilized with nitrogen (N) and phosphorus (P), alone and in combination, for seven years. Using ANCOVA, we then explored the relative importance of rock cover, precipitation, and nutrient treatment on peak aboveground biomass of spring herbaceous annual plants that were collected in 2008, 2009, 2010, and 2013. We expected surface rocks to strengthen the positive relationship between precipitation, nutrient additions, and annual plant growth. Precipitation, nutrient additions, and surface rock cover together significantly influence growth of Sonoran Desert annual plants. As expected, nutrients and precipitation were the strongest drivers of annual plant biomass. Plant growth was positively related to N additions across all four years (ANCOVA, p <0.01); P in 2008 and 2010 years (p = 0.01 and 0.005, respectively);and precipitation in three of the four years (p < 0.05). Precipitation was the primary driver of plant biomass in the two driest years, 2009 and 2013 (partial eta2 = 0.51 and 0.52, respectively). Gravel (2-64 mm diameter) was only rock size class that was significantly related to annual plant biomass. Contrary to our expecta
Evaluating water and energy fluxes across three distinct land cover types in a desert urban environment
Urbanization impacts surface energy and water balances across multiple spatial and temporal scales, which can be particularly important in desert cities where resources are limited. Urban climate observations are limited, especially over a variety of locations that represent urban land cover. To help address the lack of observations over different urban land cover types, a mobile eddy covariance tower (ECT) was deployed at three different locations in the Phoenix metropolitan area, representing a xeric landscape (drip irrigated palo verde trees with gravel), a parking lot, and a mesic landscape (sprinkler irrigated turf grass). In this project, data obtained from the mobile ECT deployments will be coupled with data from an eddy covariance tower managed by CAP LTER in the Maryvale suburb of Phoenix, Arizona. Data is processed to obtain energy and water fluxes, which are controlled by land surface characteristics, over the four distinct land cover types.

Effects of land cover and water availability on brittlebush (Encelia farinosa) flowering phenology and its pollinator community.
Phenology is the seasonal timing of environment-mediated events such as growth and reproduction. Phenology is quantified by determining time of onset and end of events, duration, and number of flowers (Augspurger 1983, Rathcke and Lacey 1985). Studies of flowering and leafing phenology have dramatically increased during the last few decades due to growing concerns over global climate change and because phenology is a highly sensitive indicator that researchers can use to study the effects of climate change at multiple scales (Chuine et al. 2000, Sparks and Menzel 2002, Peuelas et al. 2004, Williams and Abberton 2004). Urban climatic conditions are considered similar to the changing global climate conditions; therefore, many researchers study urbanized areas as smaller scale experiments, or models, of global climate change (Ziska et al. 2003). Concerns over climate change are not the only reasons for studying urban ecosystems. It is important to create urban environments resilient to social, economic, and ecological collapse. The literature of flowering phenology in urban environments suggests that spring-blooming plants in urban environments located in temperate, Mediterranean, and boreal ecosystems in North America, Europe, and China tend to bloom earlier in the city than in the surrounding un-urbanized habitat (Roetzer et al. 2000, Fitter and Fitter 2002, White et al. 2002, Ziska et al. 2003, Zhang et al. 2004). Moreover, non-woody plants, early spring bloomers, and insect-pollinated plants in these environments tend to be more sensitive than woody plants, mid- or late-spring bloomers, and wind-pollinated plants (Fitter and Fitter 2002, Traidl-Hoffman et al. 2003). Finally, temperature (Heat Island Effect) has been assumed to be the cause of earlier flowering in the urban environments since the large-scale advancement of flowering has been strongly correlated with global warming. Study of flowering phenology in urban ecosystems is important because changes in phen

ABoVE: Fractional Open Water Cover for Pan-Arctic and ABoVE-Domain Regions, 2002-2015
This data set provides land surface fractional open water cover maps for two overlapping regions: the entire pan-Arctic region (latitude > 45 degrees) and the Arctic-Boreal Vulnerability Experiment (ABoVE) domain across Alaska and Canada. The data are a 10-day averaged time step at 5-km spatial resolution for the period 2002-2015. Data represent the aerial portion of a grid cell covered by open water. The data were produced using high frequency (89 GHz) brightness temperatures from the Advanced Microwave Scanning Radiometer for EOS (AMSR-E) and the Advanced Microwave Scanning Radiometer 2 (AMSR2), with other ancillary inputs from AMSR-E/AMSR2 25-km products and the Moderate Resolution Imaging Spectroradiometer (MODIS). The resulting data record for fractional water is suitable for documenting open water patterns and inundation dynamics in boreal-Arctic ecosystems experiencing rapid climate change.
