Essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. Lythrum salicaria has not been previously subjected to examination of its volatile oil. The present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using c...

Epidemiological data indicate a beneficial effect of Mediterranean diets on human health, especially on the prevalence of cardiovascular disease. These observations are supported by recent intervention studies. However, very little is known about the current role of local Mediterranean food products, which are consumed on a less regular basis and their contribution to a healthy diet. The Europe...

Sex allocation theory addresses how separate sexes can evolve from hermaphroditism but little is known about the genetic potential for shifts in sex allocation in flowering plants. We tested assumptions of this theory using the common currency of biomass and measurements of narrow-sense heritabilities and genetic correlations in Schiedea salicaria, a gynodioecious species under selection for gr...

Two new endemic Hawai'ian Lepidoptera species are herein described. The first, Pseudoschrankia brevipalpis sp. nov., is a pollinator of the rare endemic plant Schiedea kaalae Wawra. The second, Thyrocopa keliae sp. nov., is endemic to Moloka'i island. Observations of undescribed parasitic mites that attack Hawai'ian Lepidoptera are presented as well.
