Authors: Emma C Underwood, Rachel A Hutchinson, Joshua H Viers, T Rodd Kelsey, Trisha Distler, Jaymee Marty Abstract: Change in land use in agriculturally dominated areas is often assumed to provide positive benefits for land-owners and financial agricultural returns at the expense of biodiversity and other ecosystem services. For an agriculturally dominated Read more…

Authors: Mehrey G Vaghti, Marcel Holyoak, Amy Williams, Theresa S Talley, Alexander K Fremier, Steven E Greco Abstract: Societal constraints often limit full process restoration in large river systems, making local rehabilitation activities valuable for regeneration of riparian vegetation. A target of much mitigation and restoration is the federally threatened Valley elderberry Read more…

Authors: NA Bogie, R Bayala, I Diedhiou, RP Dick, TA Ghezzehei Abstract: Aims: To investigate the physiological responses of groundnut (Arachis hypogea) and pearl millet (Penisetum glaucum) that were intercropped with the native evergreen woody shrubs Piliostigma reticulatum (D.C.) Hochst and Guiera senegalensis J.F. Gmel compared to control crops throughout two Read more…

Authors: Jonathan Kaplan, Renaud Travadon, Monica Cooper, Vicken Hillis, Mark Lubell, Kendra Baumgartner Abstract: Despite the high likelihood of infection and substantial yield losses from trunk diseases, many California practitioners wait to adopt field-tested, preventative practices (delayed pruning, double pruning, and application of pruning-wound protectants) until after disease symptoms appear in Read more…

Authors: Joshua H Viers, John N Williams, Kimberly A Nicholas, Olga Barbosa, Inge Kotzé, Liz Spence, Leanne B Webb, Adina Merenlender, Mark Reynolds Abstract: With some of the highest biodiversity on the planet, the Mediterranean Biome is experiencing a conservation crisis driven by high human population density, development, and habitat fragmentation. Read more…

Authors: Zachary L Steel, Anna E Steel, John N Williams, Joshua H Viers, Pablo A Marquet, Olga Barbosa Abstract: The Mediterranean climate region of central Chile is rich in biodiversity and contains highly productive agricultural lands, which creates challenges for the preservation of natural habitats and native biodiversity. Ecological data and studies Read more…

Authors: Jorge Andres Morandé, Christine M Stockert, Garrett C Liles, John N Williams, David R Smart, Joshua H Viers Abstract: Background: Quantifying terrestrial carbon (C) stocks in vineyards represents an important opportunity for estimating C sequestration in perennial cropping systems. Considering 7.2 M ha are dedicated to winegrape production globally, Read more…

Authors: Alison A. Whipple, Joshua Viers Abstract: Modifications to landscapes and flow regimes of rivers have altered the function, biodiversity, and productivity of freshwater ecosystems globally. Reestablishing geomorphological and hydrological conditions necessary to sustain ecosystems is a central challenge for restoration within highly altered systems. Meeting this challenge requires simultaneously Read more…

Authors: Josué Medellín-Azuara, Julien J Harou, Richard E Howitt Abstract: Given the high proportion of water used for agriculture in certain regions, the economic value of agricultural water can be an important tool for water management and policy development. This value is quantified using economic demand curves for irrigation water. Read more…

Authors: Josué Medellín-Azuara, Julien J. Harou, Marcelo A. Olivares. Kaveh Madani, Jay R. Lund, Richard E. Howitt, Stacy K. Tanaka, Marion W. Jenkins, Tingju Zhu Abstract: Economically optimal operational changes and adaptations for California’s water supply system are examined for a dry form of climate warming (GFDL CM2.1 A2) with Read more…
