Erika is an active researcher in terrestrial and freshwater ecology, in particular investigating biogeochemical cycling and nutrient stoichiometry of low nutrient systems in the Arctic. She is a member of the Under-ice ecology project, Aquatic Transitions working group, and Kangerlussuaq cross-system international working group.

Career overview

2014 – 2016: Postdoctoral Research Associate, Loughborough University. NERC funded multidisciplinary project investigating the role of dissolved organic matter (DOM) in regulating microbial and algal diversity, community structure and the cycling of organic carbon in arctic lakes.

2013 – 2017: Postdoctoral Research Associate, Loughborough University. NERC funded multidisciplinary project studying sediment records from Arctic lakes in Greenland, Alaska and Norway to determine vegetation changes associated with past climate warming events and how these have impacted on lake structure and function.

2010 – 2013: Postdoctoral Research Associate, Loughborough University. NERC funded multidisciplinary project investigating the effects of long range nitrogen deposition on arctic lake ecology.

2010: Postdoctoral Research Associate, OPAL (Open Air Laboratories) and The British Lichen Society.  Analysing public participation data from the air quality survey, running outreach sessions on lichen identification and lichens and air pollution, producing educational resources.

2009 – 2010: Postdoctoral Research Associate School of Biology, The University of Nottingham. CARBONorth project.  Investigating the effects of nitrogen enrichment and temperature on tree seedling growth at the Russian treeline.

2005 – 2009:   Ph.D School of Biology, The University of Nottingham. Thesis entitled ‘Nitrogen-phosphorus relationships in lichens’.

Research areas

Dr Whiteford's research interests focus on:

  • the impacts of environmental change on aquatic and terrestrial ecology, with a particular focus on whole organism biochemistry and physiology.
  • the mechanisms which enable lichen forming fungi to tolerate extreme, nutrient poor habitats, how they can be used as biological indicators and what role they play in shaping low resource ecosystem structure and function.
  • the effects of changes in the biogeochemical cycling of nutrients (carbon, nitrogen and phosphorus) on the structure and function of low-resource habitats, especially the Arctic.
  • taking palaeoecological and contemporary ecological approaches, undertaking limnological surveys, growth bioassays, nutrient analyses and using multiproxy palaeoecological techniques.

Erika's areas of expertise are:

  • in the analysis of lake sediments for fossil diatom assemblages and algal chlorophyll and carotenoid pigments to reconstruct environmental change impacts on lakes over time.
  • in the analysis of water, algal, plant and soil samples for chemical composition and extracellular enzyme activity associated with nutrient acquisition.  This combination of skills means she can apply knowledge from field observations, contemporary studies and experimental bioassays from both aquatic and terrestrial systems to help interpret environmental change from palaeoecological reconstructions in high latitude ecosystems.
  • investigating cross-system linkages and biogeochemical transfers between key ecosystems at the landscape scale.

Dr Whiteford is currently involved in a NERC funded multidisciplinary research project which aims to examine the influence of aeolian derived elements on the water chemistry and microbial nutrient limitation of oligotrophic freshwater lakes in West Greenland.

Her current research interests include:

  • The ecophysiology of nitrogen sensitive and tolerant lichens
  • The desiccation resistance of diatoms
  • The effect of nutrient availability on Arctic periphyton colonisation rate and community structure
  • The composition of benthic algal mats and response to nutrient supply in Arctic lakes
  • The physiological response of lichens to nitrogen enrichment in the Arctic
  • The relationship between lake morphometry and diatom community structure
