    • Assessing the impacts of the decline of Tsuga canadensisstands on two amphibian species in a New England forest 

      Siddig, Ahmed Ali; Ellison, Aaron M.; Mathewson, Brooks (Wiley-Blackwell, 2016)
      Disturbances such as outbreaks of herbivorous insects and pathogens can devastate unique habitats and directly reduce biodiversity. The foundation tree species Tsuga canadensis (eastern hemlock) is declining due to infestation ...

    • Changes in canopy structure and ant assemblages affect soil ecosystem variables as a foundation species declines 

      Kendrick, J.A.; Ribbons, R.R.; Classen, A.T.; Ellison, Aaron M. (Ecological Society of America, 2015)
      The decline of Tsuga canadensis (eastern hemlock) – a foundation tree species – due to infestation by Adelges tsugae (hemlock woolly adelgid) or its complete removal from a stand by salvage logging dramatically affects ...

    • Distribution and mixing of old and new nonstructural carbon in two temperate trees 

      Richardson, Andrew D; Carbone, Mariah S; Huggett, Brett A; Furze, Morgan E; Czimczik, Claudia I; Walker, Jennifer C; Xu, Xiaomei; Schaberg, Paul G; Murakami, Paula (BlackWell Publishing Ltd, 2015)
      We know surprisingly little about whole-tree nonstructural carbon (NSC; primarily sugars and starch) budgets. Even less well understood is the mixing between recent photosynthetic assimilates (new NSC) and previously stored ...

    • Foundation Species Loss and Biodiversity of the Herbaceous Layer in New England Forests 

      Ellison, Aaron M.; Barker Plotkin, Audrey A.; Khalid, Shah (MDPI AG, 2015)
      Eastern hemlock (Tsuga canadensis) is a foundation species in eastern North American forests. Because eastern hemlock is a foundation species, it often is assumed that the diversity of associated species is high. However, ...

    • Responses of terrestrial ecosystems and carbon budgets to current and future environmental variability 

      Medvigy, D.; Wofsy, Steven Charles; Munger, J. William; Moorcroft, Paul R (Proceedings of the National Academy of Sciences, 2010)
      We assess the significance of high-frequency variability of environmental parameters (sunlight, precipitation, temperature) for the structure and function of terrestrial ecosystems under current and future climate. We ...

    • Soil Respiration in a Northeastern US Temperate Forest: A 22-Year Synthesis 

      Giasson, M.-A.; Ellison, Aaron M.; Bowden, R. D.; Crill, P. M.; Davidson, E. A.; Drake, J. E.; Frey, S. D.; Hadley, J; Lavine, M.; Melillo, J. M.; Munger, J. W.; Nadelhoffer, K. J.; Nicoll, L.; Ollinger, S. V.; Savage, K. E.; Steudler, P. A.; Tang, J.; Varner, R. K.; Wofsy, Steven C.; Foster, David Russell; Finzi, A. C. (Ecological Society of America, 2013)
      To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter-annual variations in soil respiration (R\(_{s}\)), we analyzed more than 100,000 ...
