Fokus för Kais doktorandprojekt är hur lokala variationer i omgivningen påverkar hur arktiska och alpina växter reagerar när temperaturen ökar som följd av klimatförändringar, till exempel om växtpopulationer i varmare mikroklimat redan i dag är bättre anpassade att möta framtiden. Se mer nedan.
Opponent vid seminariet är Anthony Verboom, och examinator Mats Olsson, båda från institutionen för biologi och miljövetenskap. Kais huvudhandledare Anne D. Bjorkman (BioEnv) med Johan Uddling Fredin (BioEnv) som bihandledare.
Kort sammanfattning (på engelska):
Arctic and alpine ecosystems are warming rapidly, but plants do not experience climate change uniformly across the landscape. Fine-scale variation in topography, moisture, snow dynamics, and temperature can create strong local differences in microclimate, potentially influencing both the persistence of cold-adapted species and the capacity of plant populations to respond to warming. In this half-time seminar, I will focus on two main parts of my PhD project. First, I will present results from multiyear microclimate and vegetation data from alpine tundra in northern Sweden, examining how local thermal and hydrological conditions may create microrefugia for climate-sensitive vegetation. Second, I will present preliminary results from my reciprocal transplant experiment, which asks, among other things, whether warmer microhabitats within Arctic landscapes harbor warm-adapted subpopulations of tundra plants. This part of the project explores how landscape heterogeneity may contribute to genetic variation and local adaptation, and how this may in turn support the persistence of Arctic vegetation under climate change. Together, these studies highlight that plant responses to climate change depend not only on regional warming trends, but also on fine-scale landscape variation that shapes both local buffering and adaptive potential
