download issueWhat is Ecological Stoichiometry?
Ecological stoichiometry is a field of scientific research that examines the balance of multiple chemical elements and energy in ecological interactions. Ratios Matter (our newsletters name) because the theory behind ecological stoichiometry makes predictions about how the relative ratios of elements (like nitrogen and phosphorus) affect diverse biological and ecological processes. If you’ve ever had a field of crops, a garden, or even a houseplant you are probably familiar with the basic idea – you grow these plants in specific types of soil and add certain fertilizers because they need specific amounts of key nutrients like nitrogen and phosphorus to grow. If there is a very high ratio of nitrogen to phosphorus in the soil, adding more nitrogen will not help the plant grow because its growth is still limited by how much phosphorus it can acquire.
Ecological stoichiometry is not just about growing crops though! We have a growing community of scientists working on ecological stoichiometry because of its wide applicability to understand nutrition and its effects on the environment. Scientists have used ecological stoichiometry to study harmful algal blooms in lakes, fish production in aquaculture and in nature, the growth of cancerous tumors, the possibility that life could exist on other planets, the effects of changing dietary patterns in humans, and an endless variety of other questions.

Meet the Editorial Team

Paul Frost, Editor-in-Chief
Trent University, Canada
Paul is the David Schindler Professor of Aquatic Science at Trent University where his research program examines the role of nutrients in aquatic food webs through their effects on the nutritional physiology of plants and animals. He has on-going research on the elemental nutrition of freshwater algae and zooplankton and how this affects nutrient dynamics in lakes.

Francis Brearley
Manchester Metropolitan University, UK
Francis is a Senior Lecturer in Ecology at Manchester Metropolitan University interested in diversity and functioning of tropical rainforests.

Robert Buchkowski
Western University, Canada
Robert is an NSERC Postdoctoral Fellow at Western University in London, Ontario. He studies the role animals, plants, and microorganisms play in cycling of elements through terrestrial ecosystems using field experiments and theoretical models.

Jessica Corman
University of Nebraska-Lincoln, USA
Jessica is an Assistant Professor in the School of Natural Resources and a Daugherty Water for Food Global Institute Faculty Fellow at the University of Nebraska-Lincoln. Her research program focuses on understanding the processes that link carbon, nitrogen, and phosphorus cycles. Her work is mostly in lakes and streams, but spans from heavily altered regions to wilderness areas.

Catriona Jones
Trent University, Canada
Catriona is a PhD candidate at Trent University. She is investigating the use of genomics techniques to detect and monitor stoichiometric imbalances in freshwater invertebrates.

James Larson
US Geological Survey, USA
James is a researcher at the U.S. Geological Survey. James studies the processes that support ecosystem services in large aquatic ecosystems (e.g., the Mississippi River, Great Lakes, etc.). This includes research on biogeochemistry, food web dynamics, community composition and harmful cyanobacterial blooms.

Charlotte Narr
Southern Illinois, USA
Charlotte is an assistant professor at Southern Illinois University. She studies the causes and consequences of nutrient flows through aquatic organisms to inform our understanding of aquatic parasite-host interactions and floodplain nutrient management.

Brittany Perrotta
McMaster University, Canada
Brittany is a postdoctoral associate with the USGS - Columbia Environmental Research Center and McMaster University. She studies how microbial communities, macroinvertebrates, and food webs respond to anthropogenic stressors including emerging/legacy contaminants and nutrient pollution.

Clay Prater
Oklahoma State University, USA
Clay’s work consists of studying elemental variation across biological scales.

Judith Sitters
Vrije Universiteit Brussel, Belgium
Judith is a postdoc at the Vrije Universiteit Brussel in Belgium where she studies soil-plant-herbivore interactions, specifically focusing on the dynamics of plant and herbivore communities, in relation to carbon, nitrogen and phosphorus fluxes and stoichiometry.

Dedmer van de Waal
Netherlands Institute of Ecology, Netherlands
Dedmer is a senior scientist at the Netherlands Institute of Ecology, where he studies the impacts of global change on the eco-physiology of (toxic) phytoplankton from a stoichiometric perspective.

Nicole Wagner
Baylor University, USA
Nicole is a postdoctoral associate in the Center for Reservoir and Aquatic Systems Research at Baylor University, where she studies how the supply of nutrients and their ratios affect harmful algal bloom growth, stoichiometry and cyanotoxin production. She also examining how farm ponds can be used to decreased sediment and nutrient transport to down stream rivers and lakes.
