Alona Armstrong

Dr. Alona Armstrong

Dr. Armstrong is currently a Natural Environment Research Council Industrial Innovation Fellow and a Senior Lecturer in Energy & Environmental Sciences. She is in the Plant, Soil and Land Systems research group within Lancaster Environment Centre and a core member of Energy Lancaster, leading the Energy & Environment Theme.

Dr. Armstrong’s research focuses on the implications of the low carbon energy transition on the local environment, including ecosystem function, properties and service provision. She uses a range of desk, field, laboratory and modelling approaches to resolve understanding, taking a positive approach – we need to decarbonise energy supplies and there will be more land take for renewable energy infrastructure but how can we do this whilst maximising environmental co-benefits? Working collaboratively with stakeholders from across sectors is central to her work. Prior to her energy research, Dr. Armstrong focused on the response of peatland carbon cycling to land management perturbations.

Dr. Gwen Arnold

Gwen Arnold is an Assistant Professor of Environmental Policy in the Department of Environmental Science and Policy. She investigates the governance of high-volume hydraulic fracturing (fracking), a technique for oil and gas drilling that has transformed the energy sector over the past 15 years. With a joint PhD in political science and public policy, she examines how communities use regulation, planning, collaboration, and financial investment to manage the fracking industry; how citizens gain and interpret information about fracking and its impacts; and the factors that affect the extent to which citizens engage in policy debates and discussions about fracking. Her work on these topics has been published in Ecological Economics, Energy Policy, Public Administration Review, Publius, and Policy Studies Journal, among others. She is currently funded by the National Science Foundation to examine strategies that rural communities in Ohio, Pennsylvania, and West Virginia use to capture benefits from and mitigate adverse impacts of oil and gas boom-bust cycles.

Karen Tanner

Karen E. Tanner, Ph.D. (2020 Graduate)

In my work with Dr. Ingrid ParkerDr. Rebecca R. HernandezDr. Kara A. Moore, and Dr. Bruce M. Pavlik, I use demographic matrix models to explore the effects of microsite and climatic variability on demographic processes, to ask whether rare, common, and exotic annual species respond differently to these factors, and ultimately assess how response indicates potential for long-term population persistence. Sensitivity analyses of these models show that population growth estimates improve with higher seed bank survival rates, and indeed population performance and persistence likely hinge on belowground dynamics for these and other annual species forming persistent seed banks. Because moisture is known to negatively affect seed survival in other systems, possibly by facilitating soil pathogen attack, novel moisture gradients created by solar infrastructure may have a strong effect on annual plant population dynamics. In 2017-2019, I tested for effects of shade and fungicide treatment as well as seed age on seed viability and germination rates of native and exotic species, incorporating these data into models predicting how microhabitat conditions may drive shifts in population performance and community composition.
