Almond Board of California

  • Title: Remote-controlled evaluation of distribution uniformity and stem water potential: Extending imagery to integrated decision support

The proposed project will address procedural obstacles and knowledge gaps through an aggressive outreach campaign, new integrated irrigation decision support, and user-friendly remote sensing tools to quickly transform imagery to actionable information We will bridge the deep understanding of almond production in public research and extension with sustainability- focused data scientists and developers (Conservation Science Partners) to build open source tools that will allow multiple hardware and software technologies to integrate new DU and SWP algorithms.

Ultimately, all of our model projects and forest carbon maps will be made publicly available through an open-source web platform, enabling land managers to understand how forest carbon might change into the future and evaluate current management strategies.

NSF Integrative Biology

  • Title: Integrative Demography: Combining Ecology, Remote Sensing, and Genomics to Understand Population Dynamics
  • Summary: Biodiversity — arising from the persistence of natural populations — provides critical ecosystem services for human life. Successfully predicting population growth or decline depends on identifying key genetic, organismal, and environmental drivers and integrating them into quantitative, predictive models. Here, a team with diverse expertise in quantitative genetics, genomics, ecology, and remote sensing will integrate advances in their fields to develop new and transformative integrative demography (IntDemo) models. These IntDemo models will enable prediction of population dynamics in response to changing environments and as a function of genetic composition; in so doing they will integrate across scales, using individual genotype and life history observations along with local environmental data to predict the emergent property of multi-generational population dynamics. These models will also be used to predict responses to future change and to provide tools to direct the implementation of conservation strategies such as assisted migration or gene flow.
