Environmental driver effects on population growth rates vary by rarity type and variation in demographic rate sensitivity
… populations. Further, results from a climate warming experiment suggests variation in life history across populations is partly driven by temperature differences. In a separate study, I test the niche breadth hypothesis, which postulates that driver effect sizes should decrease with range …

The effects of warming on carbon and microbial community wetland dynamics at Turnbull National Wildlife Refuge, Washington
… cycling of carbon. In the face of global warming, wetland hydroperiods could shift causing changes in their functionality. My field experiment surveyed 3 plots within 12 wetlands of each hydroperiod class (i.e. 12 permanent, 12 semi-permanent, 12 ephemeral). This survey was paired with a …

Experimental warming of subarctic biocrust: Temporal responses of soil respiration and plant community
… This research project focuses on the effects of warming on soil respiration in biocrust, on a diurnal and a seasonal scale. It also focuses on species composition changes of vascular plants in the warming experiment where warming was induced with open-top chambers (OTCs). Soil respiration, …

The Impacts of Disruptive Environmental Change on Vital Microbial Ecosystems
… services and stability. Through a mix of experiments, observational studies, and theory, we investigate the dynamic interplay between microbes and their changing environment.</p><p>In our first research chapter, we address these questions using data from a longterm whole-ecosystem warming …

Links between climate feedbacks and the large-scale circulation across idealized and complex climate models
… the atmospheric circulation across ensembles of experiments from idealized and complex general circulation models (GCMs). I first demonstrate that an existing, widely-used type of idealized GCM — the dynamical core model — has climate feedbacks that are explicitly prescribed and determined by a …

Sub-Antarctic plant-soil interactions in a changing world: plant N acquisition and growth under warming on Marion Island
… through direct oN acquisition. Climate warming in cold ecosystems under global change is expected to alleviate the temperature limitations to soil decomposition, effectively increasing N-availability through iN release. This has resulted in predictions for stronger indirect than direct …
