The marbled crayfish as a paradigm for saltational speciation by autopolyploidy and parthenogenesis in animals

The parthenogenetic all-female marbled crayfish is a novel research model and potent invader of freshwater ecosystems. It is a triploid descendant of the sexually reproducing slough crayfish, Procambarus fallax, but its taxonomic status has remained unsettled. By cross-breeding experiments and parentage analysis we show here that marbled crayfish and P. fallax are reproductively separated. Both...

Evidence-based bioactive phytoconstituents for human health and disease prevention

The term “medicinal” as applied to a plant indicates that it contains a substance or substances which modulate beneficially the physiology of sick mammals. Thousands of species of higher plants have been used by man for that purpose. Modern techniques have revealed the enormous variety and complexity of so-called secondary plant chemicals, i.e., those which do not occur in all species, but whic...
