  • Landscape position mediates drought vulnerability in California valley oak (Quercus lobata)

    Open AccessMatthew L Trumper, Daniel Griffin et al.ARTICLEEnvironmental Research Letters2024

    Future climate change will exacerbate drought stress in water-limited ecosystems. However, topography can alter the fine-scale climatic and hydrologic conditions that mediate plant response to meteorological drought. Here, with six new valley oak ( Quercus lobata ) tree-ring width chronologies, we assess how topography acts as a mediating factor on tree growth and drought sensitivity. Because valley oaks are known to be highly dependent on subsur…

  • Best Practices for Sustainable Inter-Institutional Hybrid Learning at CHARM European University

    Open AccessDaniel Griffin, Silvia Elena Gallagher et al.ARTICLEEducation Sciences2022

    CHARM European University offers an inter-institutional Master’s (MSc) in Global Challenges for Sustainability across five European university campuses using innovative, challenge-based, transdisciplinary, and student-centered pedagogies. However, delivering modules across multiple locations at the same time poses a major challenge. Multiple hybrid classrooms solve this challenge by offering spaces for students and staff to teach and learn locall…

  • Google Scholar – Platforming the scholarly economy

    Open AccessJake Goldenfein, Daniel GriffinARTICLEInternet Policy Review2022

    Google Scholar has become an important player in the scholarly economy. Whereas typical academic publishers sell bibliometrics, analytics and ranking products, Alphabet, through Google Scholar, provides "free" tools for academic search and scholarly evaluation that have made it central to academic practice. Leveraging political imperatives for open access publishing, Google Scholar has managed to intermediate data flows between researchers, resea…

  • Search quality complaints and imaginary repair

    Open AccessDaniel Griffin, Emma LurieARTICLENew Media & Society2022Citada por: 1Referencias: 11

    In early 2017, a journalist and search engine expert wrote about “Google’s biggest ever search quality crisis.” Months later, Google hired him as the first Google “Search Liaison” (GSL). By October 2021, when someone posted to Twitter a screenshot of misleading Google Search results for “had a seizure now what,” users tagged the Twitter account of the GSL in reply. The GSL frequently publicly interacts with people who complain about Google Search…

  • Gigapixel Macro Photography of Tree Rings

    Daniel Griffin, Samantha T Porter et al.ARTICLETree-Ring Research2021

    High quality specimen digitization is becoming standard across the sciences, is relevant for curation of natural history collections, and must become a priority for dendrochronology. This paper overviews the enduring role of imaging in dendrochronology, summarizes the potential relevance of gigapixel macro photography of polished specimens, offers a long-term review of a commercial imaging system, and reports our progress imaging entire collectio…

  • Uniform shrub growth response to June temperature across the North Slope of Alaska

    Open AccessDaniel Ackerman, Daniel Griffin et al.ARTICLEEnvironmental Research Letters2018

    The expansion of woody shrubs in arctic tundra alters many aspects of high-latitude ecosystems, including carbon cycling and wildlife habitat. Dendroecology, the study of annual growth increments in woody plants, has shown promise in revealing how climate and environmental conditions interact with shrub growth to affect these key ecosystem properties. However, a predictive understanding of how shrub growth response to climate varies across the he…

  • On the Production of Climate Information in the High Mountain Forests of Guatemala

    Diego Pons, Matthew J Taylor et al.ARTICLEAnnals of the American…2017Referencias: 44

    Guatemala's population is dependent on cash crops and subsistence agriculture, the yield of which depends on both the timing and quantity of rainfall. Detailed knowledge about Guatemala's past, current, and future climate is therefore critical to the well-being of a country so reliant on agriculture. Relatively little information about Guatemala's climate exists, though, due to sparse instrumental records and limited high-resolution paleoclimate …

  • The Relationship Between Earlywood and Latewood Ring-Growth Across North America

    Max C A Torbenson, D W Stahle et al.ARTICLETree-Ring Research2016

    The relationship between earlywood width (EW) and latewood width (LW) is investigated using 197 tree-ring collections representing several tree species from across the North American continent. Chronologies of LW have limited paleoclimate value when they have low variance or very high correlation with EW from the same site. The correlation of LW and EW can be removed by taking the residuals from linear regression to provide a chronology of discre…

  • How unusual is the 2012–2014 California drought?

    Open AccessDaniel Griffin, Kevin J AnchukaitisARTICLEGeophysical Research Letters2014

    For the past three years (2012–2014), California has experienced the most severe drought conditions in its last century. But how unusual is this event? Here we use two paleoclimate reconstructions of drought and precipitation for Central and Southern California to place this current event in the context of the last millennium. We demonstrate that while 3 year periods of persistent below‐average soil moisture are not uncommon, the current event is…

  • Signal Strength In Sub-Annual Tree-Ring Chronologies from Pinus ponderosa In Northern New Mexico

    Becky Brice, Kara K Lorion et al.ARTICLETree-Ring Research2013

    The creation of chronologies from intra-annual features in tree rings is increasingly utilized in dendrochronology to create season-specific climate histories, among other applications. A conifer latewood-width network has recently been developed for the southwestern United States, but considerable uncertainty remains in understanding site and species differences in signal strength and sample depth requirements. As part of the 22nd annual North A…

  • Monsoon precipitation reconstructed from tree rings in the southwestern United States

    Open AccessDaniel Griffin, Connie A Woodhouse et al.ARTICLEQuaternary International2013

  • Latewood Chronology Development for Summer-Moisture Reconstruction In the US Southwest

    Daniel Griffin, David M Meko et al.ARTICLETree-Ring Research2011

    Tree-ring studies have demonstrated that conifer latewood measurements contain information on long-term North American monsoon (NAM) variability, a hydroclimatic feature of great importance to plants, animals, and human society in the US Southwest. This paper explores data-treatment options for developing latewood chronologies aimed at NAM reconstruction. Archived wood samples for five Douglas-fir (Pseudotsuga menziesii, Mirb. Franco) sites in so…
