Demographic responses of Pinguicula ionantha to prescribed fire: a regression-design LTRE approach.

This study describes the use of periodic matrix analysis and regression-design life table response experiments (LTRE) to investigate the effects of prescribed fire on demographic responses of Pinguicula ionantha, a federally listed plant endemic to the herb bog/savanna community in north Florida. Multi-state mark-recapture models with dead recoveries were used to estimate survival and transition probabilities for over 2,300 individuals in 12 populations of P. ionantha.

Bi-parental cytoplasmic DNA inheritance in Wisteria (Fabaceae): evidence from a natural experiment.

Cytoplasmic inheritance was investigated in interspecific hybrids of Wisteria sinensis and W. floribunda. Species-specific nuclear, mitochondrial and plastid DNA markers were identified from wild-collected plants of each species in its native range.

Molecular phylogenetics of the Macaronesian-endemic genus Bystropogon (Lamiaceae): palaeo-islands, ecological shifts and interisland colonizations.

Abstract A molecular phylogenetic study of Bystropogon L'Her. (Lamiaceae) is presented. We performed a cladistic analysis of nucleotide sequences of the internal transcribed spacers (ITS), of the nuclear ribosomal DNA, and of the trnL gene and trnL-trnF intergenic spacer of the chloroplast DNA.
