  • Growing season moisture drives interannual variation in woody productivity of a temperate deciduous forest 
    Helcoski, Ryan; Tepley, Alan J.; Pederson, Neil; McGarvey, Jennifer C.; Meakem, Victoria; Herrmann, Valentine; Thompson, Jonathan R.; Anderson-Teixeira, Kristina J. (2019)
    1.The climate sensitivity of forest ecosystem woody productivity (ANPPstem ) influences carbon cycle responses to climate change. For the first time, we combine long-term annual growth and forest census data of a diverse ...
  • Joint effects of climate, tree size, and year on annual tree growth derived from tree-ring records of ten globally distributed forests 
    Anderson-Teixeira, Kristina J.; Herrmann, Valentine; Rollinson, Christine R.; Gonzalez, Bianca; González-Akre, Erika B.; Pederson, Neil; Alexander, M. Ross; Allen, Craig D.; Alfaro-Sanchez, Raquel; Awada, Tala; Baltzer, Jennifer L.; Baker, Patrick J.; Birch, Joseph D.; Bunyavejchewin, Sarayudh; Cherubini, Paolo; Davies, Stuart J.; Dow, Cameron; Helcoski, Ryan; Kaspar, Jakub; Lutz, James A.; Margolis, Ellis Q.; Maxwell, Justin T.; McMahon, Sean M.; Piponiot, Camille; Russo, Sabrina E.; Samonil, Pavel; Sniderhan, Anastasia E.; Tepley, Alan J.; Vasickova, Ivana; Vlam, Mart; Zuidema, Pieter A. (2021)
    Tree rings provide an invaluable long-term record for understanding how climate and other drivers shape tree growth and forest productivity. However, conventional tree-ring analysis methods were not designed to simultaneously ...
  • Long-Term Impacts of Invasive Insects and Pathogens on Composition, Biomass, and Diversity of Forests in Virginia's Blue Ridge Mountains 
    Anderson-Teixeira, Kristina J.; Herrmann, Valentine; Cass, Wendy B.; Williams, Alan B.; Paull, Stephen J.; González-Akre, Erika B.; Helcoski, Ryan; Tepley, Alan J.; Bourg, Norman A.; Cosma, Christopher T.; Ferson, Abigail E.; Kittle, Caroline; Meakem, Victoria; McGregor, Ian R.; Prestipino, Maya N.; Scott, Michael K.; Terrell, Alyssa R.; Alonso, Alfonso; Dallmeier, Francisco; McShea, William J. (2021)
    Exotic forest insects and pathogens (EFIP) have become regular features of temperate forest ecosystems, yet we lack a long-term perspective on their net impacts on tree mortality, carbon sequestration, and tree species ...
  • No significant increase in tree mortality following coring in a temperate hardwood forest 
    Helcoski, Ryan; Tepley, Alan J.; McGarvey, Jennifer C.; González-Akre, Erika B.; Meakem, Victoria; Thompson, Jonathan R.; Anderson-Teixeira, Kristina J. (2019)
    The collection of tree-ring data from living trees is widespread and highly valuable in ecological and dendro-climatological research, yet there is concern that coring injures trees, potentially contributing to mortality. ...
  • Tree height and leaf drought tolerance traits shape growth responses across droughts in a temperate broadleaf forest 
    McGregor, Ian R.; Helcoski, Ryan; Kunert, Norbert; Tepley, Alan J.; González-Akre, Erika B.; Herrmann, Valentine; Zailaa, Joseph; Stovall, Atticus E. L.; Bourg, Norman A.; McShea, William J.; Pederson, Neil; Sack, Lawren; Anderson-Teixeira, Kristina J. (2020)
