Helianthemum Türkiye’de 4’ü endemik olmak üzere 19 takson ile temsil edilmektedir. Bu çalışmada doğal olarak yetişen oelandicum subsp. incanum toprak üstü kısımlarının etanollü (%75) ve sulu ekstrelerinin antioksidan, anti-inflamatuvar hipoglisemik aktiviteleri araştırılmıştır. Sulu ekstrenin DPPH ABTS radikalleri üzerine gösterdiği süpürücü etki miktarı sırasıyla 67.26±0.49 68.08±0.41 µg ml-1 ...

Seed banks play a crucial role in arid plant communities because they confer stability and longterm persistence. However, seed banks have high temporal and spatial variability, with dramatic changes in density and composition. The aim of this study was to test whether seasonal change affected seed bank community structure and spatial pattern. Moreover, we wanted to know if the effect driven by ...

Whereas warming enhances plant nutrient status and photosynthesis in most terrestrial ecosystems, dryland vegetation is vulnerable to the likely increases in evapotranspiration and reductions in soil moisture caused by elevated temperatures. Any warming-induced declines in plant primary production and cover in drylands would increase erosion, land degradation, and desertification. We conducted ...

Abstract We use Helianthemum oelandicum subsp. as a model for studies of mechanisms shaping the diversity in rapidly radiating lineage H. aggregate. Locally, correlations between drainage conditions (using GIS to measure variation micro-topography on more or less horizontal bedrock) and frequency alleles Mendelian genes pubescence indicated that hairs are markers adaptation unique environmental...
