    Disturbances often lead to changes in average values of community properties; however, disturbances can also affect the predictability of a community's response. We performed a meta-analysis to determine how response ...

  • Trophic level scales positively with body size in fishes 

    Romanuk, Tamara N., April Hayward, and Jeffrey A. Hutchings. 2011. "Trophic level scales positively with body size in fishes." Global Ecology and Biogeography 20(2): 231-240.
    Aim The existence of a body size hierarchy across trophic connections is widely accepted anecdotally and is a basic assumption of many food-web models. Despite a strong theoretical basis, empirical evidence has been ...
  • Processes governing riverine fish species richness are scale-independent 

    Romanuk, T. N., B. E. Beisner, A. Hayward, L. J. Jackson, et al. 2009. "Processes governing riverine fish species richness are scale-independent." Community Ecology 10(1): 17-24.
    The ability of macroecological approaches to identify the mechanisms that underlie spatial patterns in species richness has been heavily debated in part because of continued attention to the role of scale-dependence in the ...
  • Structure and robustness to species loss in Arctic and Antarctic ice-shelf meta-ecosystem webs 

    Carscallen, W. Mather A., and Tamara N. Romanuk. 2012. "Structure and robustness to species loss in Arctic and Antarctic ice-shelf meta-ecosystem webs." Ecological Modelling 245: 208-218.
    While changes in the structure and dynamics of food-webs associated with sea-ice in polar regions will be among the most pronounced ecosystem-level changes on the planet that will occur with warming temperatures, little ...
  • Food-Web Structure of Seagrass Communities across Different Spatial Scales and Human Impacts 

    Coll, Marta, Allison Schmidt, Tamara Romanuk, and Heike K. Lotze. 2011. "Food-Web Structure of Seagrass Communities across Different Spatial Scales and Human Impacts." Plos One 6(7): 22591-e22591.
    Seagrass beds provide important habitat for a wide range of marine species but are threatened by multiple human impacts in coastal waters. Although seagrass communities have been well-studied in the field, a quantification ...
  • Predicting invasion success in complex ecological networks 

    Romanuk, Tamara N., Yun Zhou, Ulrich Brose, Eric L. Berlow, et al. 2009. "Predicting invasion success in complex ecological networks." Philosophical Transactions of the Royal Society B-Biological Sciences 364(1524): 1743-1754.
    A central and perhaps insurmountable challenge of invasion ecology is to predict which combinations of species and habitats most effectively promote and prevent biological invasions. Here, we integrate models of network ...
  • Ecosystem structure and services in eelgrass Zostera marina and rockweed Ascophyllum nodosum habitats 

    Schmidt, Allison L., Marta Coll, Tamara N. Romanuk, and Heike K. Lotze. 2011. "Ecosystem structure and services in eelgrass Zostera marina and rockweed Ascophyllum nodosum habitats." Marine Ecology Progress Series 437: 51-68.
    Marine vegetated habitats provide essential functions and services to ocean ecosystems and human well-being. It is unclear, however, how different habitat types compare. Using large-scale field surveys, we compared the ...
  • Ecological realism and mechanisms by which diversity begets stability 

    Romanuk, Tamara N., Richard J. Vogt, and Jurek Kolasa. 2009. "Ecological realism and mechanisms by which diversity begets stability." Oikos 118(6): 819-828.
    We investigated how ecological realism might impact the outcome of three experimental manipulations of species richness to determine whether the patterns and the mechanisms underlying richness-variability relationships ...
  • Are natural microcosms useful model systems for ecology? 

    Srivastava, DS, J. Kolasa, J. Bengtsson, A. Gonzalez, et al. 2004. "Are natural microcosms useful model systems for ecology?." Trends in Ecology & Evolution 19(7): 379-384.
    Several recent, high-impact ecological studies feature natural microcosms as tools for testing effects of fragmentation, metacommunity theory or links between biodiversity and ecosystem processes. These studies combine the ...
  • Maintenance of Positive Diversity-Stability Relations along a Gradient of Environmental Stress 

    Romanuk, Tamara N., Richard J. Vogt, Angela Young, Constance Tuck, et al. 2010. "Maintenance of Positive Diversity-Stability Relations along a Gradient of Environmental Stress." Plos One 5(4): 10378-e10378.
    Background: Environmental stress is widely considered to be an important factor in regulating whether changes in diversity will affect the functioning and stability of ecological communities. Methodology/Principal Findings: ...
  • Reciprocal Subsidies and Food Web Pathways Leading to Chum Salmon Fry in a Temperate Marine-Terrestrial Ecotone 

    Romanuk, Tamara N., and Colin D. Levings. 2010. "Reciprocal Subsidies and Food Web Pathways Leading to Chum Salmon Fry in a Temperate Marine-Terrestrial Ecotone." Plos One 5(4): 10073-e10073.

  • Food webs: reconciling the structure and function of biodiversity

  • Robustness to thermal variability differs along a latitudinal gradient in zooplankton communities
