  Abstract In some urban environments, human activities enhance resources for avian species, providing habitat that can support year-round occupancy. If both members of a mated pair stay on their breeding territories year-round, close proximity of pair members throughout the year may increase the potential for interactions outside the breeding season. Under these circumstances, avian species that would otherwise terminate their bonds following the breeding season may form perennial pair bonds. We examined behavior of mated pairs of adult Cooper’s Hawks (Accipiter cooperii) during the nonbreeding season in an urban environment to determine whether pairs retained their breeding territories outside the breeding season and if year-round maintenance of territories influenced the duration of pair bonds. Home ranges and core areas of pair members largely overlapped. Pair members remained close to the nest site they used during the previous breeding season, avoided neighboring conspecifics of the same sex, and sele...

  PMID: 18071918;Abstract: This study investigates the application of models traditionally used to estimate erosion and sediment deposition to assess the potential risk of water quality impairment resulting from metal-bearing materials related to mining and mineralization. An integrated watershed analysis using Geographic Information Systems (GIS) based tools was undertaken to examine erosion and sediment transport characteristics within the watersheds. Estimates of stream deposits of sediment from mine tailings were related to the chemistry of surface water to assess the effectiveness of the methodology to assess the risk of acid mine-drainage being dispersed downstream of abandoned tailings and waste rock piles. A watershed analysis was preformed in the Patagonia Mountains in southeastern Arizona which has seen substantial mining and where recent water quality samples have reported acidic surface waters. This research demonstrates an improvement of the ability to predict streams that are likely to have severely degraded water quality as a result of past mining activities. © Springer Science+Business Media B.V. 2007.

  The Soil Survey of Santa Cruz and Parts of Cochise and Pima Counties, Arizona, a product of the USDA Soil Conservation Service and the Forest Service in cooperation with the Arizona Agricultural Experiment Station, released in 1979, was created according to the site conditions in 1971, when soil scientists identified soils types on aerial photographs. The scale at which these maps were published is 1:20,000. These soil maps were automated for incorporation into the hydrologic modeling within a GIS. The aerial photos onto which the soils units were drawn had not been orthoganalized, and contained distortion. A total of 15 maps composed the study area. These maps were scanned into TIFF format using an 8-bit black and white drum scanner at 100 dpi. The images were imported into ERDAS IMAGINE and the white borders were removed through subset decollaring processes. Five CD-ROMs containing Digital Orthophoto Quarter Quads (DOQQs) were used to register and rectify the scanned soils maps. Polygonal data was then attributed according to the datasets.

  In this study, a geographic information system (GIS) is used to integrate and accurately map field studies, information from remotely sensed data, watershed models, and the dispersion of potentially toxic mine waste and tailings. The purpose of this study is to identify erosion rates and net sediment delivery of soil and mine waste/tailings to the drainage channel within several watershed regions to determine source areas of sediment delivery as a method of quantifying geo-environmental analysis of transport mechanisms in abandoned mine lands in arid climate conditions. Users of this study are the researchers interested in exploration of approaches to depicting historical activity in an area which has no baseline data records for environmental analysis of heavily mined terrain.

  Abstract: Cell suspension cultures of Moricandia arvensis, a photosynthetic C3-C4 intermediate within the Brassicaceae, were recovered from cryogenic storage. Post-thaw cell viability, determined by triphenyltetrazolium chloride reduction and cell re-growth, was influenced by composition of the cryoprotectant and, positively, by incorporation into the post-thaw medium of 0.01% (w/v) of the non-ionic surfactant, Pluronic F-68. The growth characteristics of re-established suspension cultures were similar to those of non-cryopreserved suspensions. Re-established suspensions also released viable protoplasts in yields comparable to the same non-cryopreserved cell suspensions.

  Abstract: Efficient and reproducible plant regeneration has been established from stem internode explants of Moricandia arvensis, a crucifer of special interest due to its C3-C4 intermediate photosynthetic activity. Somatic embryogenesis was induced in one-third of explants cultured on Murashige and Skoog based medium containing 9 mM 2,4-dichlorophenoxyacetic acid. High frequencies of plant regeneration (>90%) resulted when somatic embryos were germinated on medium lacking growth regulators. Regenerated plants were diploid, fertile and morphologically similar to seed-derived plants of M. arvensis. This is the first report of somatic embryogenesis in M. arvensis. This plant regeneration system should facilitate gene identification and localisation studies of C3-C4 physiology by insertional mutagenesis, a prerequisite for the isolation and transfer of genes involved in C3-C4 metabolism from Moricandia to cultivated brassicas.

  Abstract: A spatial modeling approach was developed, utilizing geographic information systems (GIS) and geostatistics, to predict the production and utilization of perennial range grasses in a semidesert grassland in southern Arizona. Production and utilization data was collected and a GIS database was developed for a portion of the Santa Rita Experimental Range near Tucson, Arizona. IDRISI, a raster-based GIS, was used for analysis in this study. Forage utilization was calculated for each cell as the function of distance to water and slope. Using results from this study, land managers can estimate grazing capacities from predictor variables. -from Authors

  Integrated video and ESRI StoryMap production request by the Office of the Dean of CALS, this project uses processed geospatial data and, interviews, and data visualization to explain the nature of federal land disposal that has occurred and may accelerate under the HEARD Act. ART was approached by CALS documentary producer Cody Sheehy and CCT Director Matt Rahr to provide database construction and spatial analysis to support the project.
