Lundberg, M., 2011. Systematics and polyploid evolution in Potentilleae (Rosaceae). This thesis comprises studies of the phylogenetic relationships in the flowering plant clade Potentilleae in Rosaceae. The relationships were elucidated by using DNA sequence data from the nuclear genome as well as from the plastid genome. In particular, the focus of the studies was the investigation of allopoly...

Glycosidically bound compounds have been identified in a vast number of fruits. They have been extensively studied in the cases of grapes and wines (Williams et al., 1980, 1982 a, b; Strauss et al., 1988; Gunata et al., 1990 a, b; Roscher, Winterhalter, 1993; Baumes et al., 1994; Sefton et al., 1994) and for other fruits such as mangoes (Adedeji et al., 1992), peaches (Krammer et al., 1991; Sum...

Two new benzyl derivatives were isolated from ethyl acetate fraction of wild strawberry, Fragaria vesca var. nubicola Lindl. ex Hook.f. The structures of these compounds were elucidated to be 5-(4-hydroxy-3-methoxyphenethyl)-7-methoxy-2H-chromen-3-ol (1) and 5-(4-hydroxy-3-methoxyphenethyl)-4,7-dimethoxy-2H-chromen-3-ol (2) based on spectroscopic data through IR, UV, 1H-NMR, 13C-NMR along with ...

Intrinsic population growth rate and density dependence are fundamental components of population dynamics. Theory suggests that variation in and correlations between these parameters among patches within a population can influence overall population size, but data on the degree of variation and correlation are rare. Replicate populations of a specialist aphid (Chaetosiphon fragaefolii) were fol...

The genus Fragaria encompasses species at ploidy levels ranging from diploid to decaploid. The cultivated strawberry, Fragaria×ananassa, and its two immediate progenitors, F. chiloensis and F. virginiana, are octoploids. To elucidate the ancestries of these octoploid species, we performed a phylogenetic analysis using intron-containing sequences of the nuclear ADH-1 gene from 39 germplasm acces...
