How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
My research focuses on how energy, matter, and information shape the interactions between organisms and their environment. I work to expand models of ecosystem functioning, using a mix of field-based and theoretical studies. I do this by measuring exchanges of matter, energy, and information between organisms and their environment, and developing new theoretical models to predict how ecosystems change as a result. My goal is to improve how we predict and mitigate the impact of human activities.
January 2020 - April 2020
- Guest lecturer for the "Models in Biology" course. Guest lectures covered the topics of classic models in ecology, models of species interactions, and meta-ecology models.
February 2019 - April 2019
- Visiting scholar in research
- Placement aimed at developing a mathematical metaecosystem model describing animal-mediated nutrient transport across ecosystem boundaries in collaboration with the Schmitz Lab. I reviewed meta-ecosystem, meta-population, and animal movement literature, performed simulations of ecosystem persistence over time under different animal movement and nutrient transport scenarios, and collaborated on developing a perspective paper.

- Research Assistant
- Teaching assistant for the "Principles of Ecology" course. I managed the online learning section of the course, developing weekly new content introducing students to preeminent ecologists. I also provided administrative and academic support to students.
Fluxes of matter, energy and information over space and time contribute to ecosystems' functioning and stability. The meta‐ecosystem framework addresses the dynamics of ecosystems linked by these fluxes but, to date, has focused solely on energy and matter. Here, we synthesize existing knowledge of information's effects on local and connected ecosy...
Home range size of consumers varies with food quality, but the many ways of defining food quality hamper comparisons across studies. Ecological stoichiometry studies the elemental balance of ecological processes and offers a uniquely quantitative, transferrable way to assess food quality using elemental ratios, e.g., carbon (C):nitrogen (N). Here,...
1. Energy, nutrients, and organisms move over landscapes, connecting ecosystems across space and time. Meta-ecosystem theory investigates the emerging properties of local ecosystems coupled spatially by these movements of organisms and matter, by explicitly tracking exchanges of multiple substances across ecosystem borders. To date, meta-ecosystem...
Context Spatially explicit correlates of foliar elemental, stoichiometric, and phytochemical (ESP) traits represent links to landscape patterns of resource quality. Objectives We investigate spatial correlates for multiple foliar ESP traits at the species level and across species at the trait level for five boreal forest understory plants. Method...
The proportion of time an animal spends actively foraging in a day determines its long-term fitness. Here, we derive a general mathematical model for the scaling of this activity time with body size in consumers. We show that this scaling can change from positive (increasing with size) to negative (decreasing with size) if the detectability and ava...
Herbivores making space use decisions must consider the trade-off between perceived predation risk and forage quality. Herbivores, specifically snowshoe hares (Lepus americanus), must constantly navigate landscapes that vary in predation risk and food quality, providing researchers with the opportunity to explore the factors that govern their forag...
Intraspecific feeding choices comprise a large portion of herbivore foraging decisions. Plant resource quality is heterogeneously distributed, affected by nutrient availability and growing conditions. Herbivores navigate landscapes, foraging not only according to food qualities, but also energetic and nutritional demands. We test three non-exclusiv...
Intraspecific feeding choices account for a large portion of herbivore foraging in many ecosystems. Plant resource quality is heterogeneously distributed, affected by nutrient availability and growing conditions. Herbivores navigate landscapes, making feeding decisions according to food qualities, but also energetic and nutritional demands. We test...
Context Spatially explicit drivers of foliar chemical traits link plants to ecosystem processes to reveal landscape functionality. Specifically, foliar elemental, stoichiometric, and phytochemical (ESP) compositions represent key indicator traits. Objectives Here, we investigate the spatial drivers of foliar ESP at the species level and across spe...
Aims Intraspecific variation in plant traits has important consequences for individual fitness and herbivore foraging. For plants, trait variability across spatial dimensions is well documented. However, temporal dimensions of trait variability are less well known, and may be influenced by seasonal differences in growing degree days, temperature, a...
• Herbivores consider the variation of forage qualities (nutritional content and digestibility) as well as quantities (biomass) when foraging. Such selection patterns may change based on the scale of foraging, particularly in the case of ungulates that forage at many scales. • To test selection for quality and quantity in free‐ranging herbivores ac...
Fluxes of matter, energy, and information over space and time contribute to ecosystems’ functioning. The meta-ecosystem framework addresses the dynamics of ecosystems linked by these fluxes, however, to date, meta-ecosystem research focused solely on fluxes of energy and matter, neglecting information. This is problematic due to organisms’ varied r...
Consumers make space use decisions based on resource quality. Most studies that investigate the influence of resource quality on the spatial ecology of consumers use diverse proxies for quality including measures based on habitat classification, forage species diversity and abundance, and nutritional indicators, e.g., protein. Ecological stoichiome...
Ecosystems are open systems connected through spatial flows of energy, matter, and nutrients. Predicting and managing ecosystem interdependence requires a rigorous quantitative understanding of the drivers and vectors that connect ecosystems across spatio-temporal scales. Animals act as such vectors when they transport nutrients across landscapes i...
Intraspecific variability in ecological traits is widespread in nature. Recent evidence, mostly from aquatic ecosystems, shows individuals differing at the most fundamental level, that of their chemical composition. Age, sex, or body size and condition may be key drivers of intraspecific variability in the body concentrations of carbon (C), nitroge...

Is it possible to add details to someone listed as an author on a bioRxiv submission, after the preprint has gone online?
For instance, if an author gets an ORCID after the preprint is online on bioRxiv, is it possible to add it retroactively to that preprint?
Study of the spatial ecological stoichiometry of boreal forests in central Newfoundland, Canada, and its influence on trophic, community, and ecosystem dynamics.
