L. Walas - INSTYTUT DENDROLOGII

Represented disciplines:

Biological sciences
Forestry sciences

Research focus:

The main areas of my research include biogeography, population genetics, phylogenesis, ethnobotany, and demography of woody species, with particular attention to endemic and relic taxons.

My current focus is on studying flora that can be found in biodiversity hotspots (the Mediterranean Sea basin, Caucasus, the Irano-Anatolian region) and within European mountain ranges (the Alps, the Carpathian Mountains, and the Pyrenees).

I analyse spacial data concerning the incidence of specific species and their reaction to environmental factors, which allows me to determine the spatial patterns for plant incidence. The collected information on genetic resources, potential distribution and interactions with the environment facilitate the planning of strategies for the protection of individual species and entire ecosystems.
My research activities also include cooperation with experts specialising in such scientific disciplines as biological sciences, forestry, and medical sciences.

Keywords:
Biogeography, population genetics, relic species, distribution modelling, biodiversity protection
