various biological activities, such as antitumor, antimalarial, antifeedant, insecticidal, antiinflammatory, amoebicidal, and herbicidal effects. We are interested in such biologically active compounds and have isolated many quassinoids from plants, such as Brucea antidysenterica, Picrasma ailanthoides, and Brucea javanica. As part of these studies, we investigated the isolation of quassinoids ...

Three-of-heaven (Ailanthus altissima (Mill.) Swingle) is considered as one of the most invasive plant species worldwide in rural and urban environment. Although tree-of-heaven commonly observed throughout city Osijek (Croatia), its prevalence frequency has not been documented. This study conducted from May to September 2022 streets determine distribution, abundance competitive advantage this sp...

These six regions represent relatively discrete subpopulations, fidelity to which is determined matrilineally (Clapham and Mayo 1987). Recent genetic analysis of mitochondrial DNA (mtDNA) has indicated that this fidelity has persisted over an evolutionary timescale in at least the Icelandic and Norwegian feeding grounds (Palsbøll et al. 1995, Larsen et al. 1996). Genetic partitioning is not evi...

The underlying influences of soil flooding, pH level and soil-inhabiting Diaprepes abbreviatus (L.) root weevil larval feeding in citrus were examined in two separate greenhouse studies, rootstock flooding Diaprepes-larvae (RFD) and liming rootstock flooding Diaprepes-larvae (LRFD). Our objectives were to determine the combined effects of soil flooding and pH level on survival and growth of Dia...

The invasion of alien plant species outside their home range constitutes an emerging problem threatening native diversity. expansion is often favored in anthropogenic habitats, such as roads and urbanized areas, which allow the rapid colonization new sites by these species. development suitable monitoring methods fundamental both to keep pace with fast dynamics enable appropriate prompt control...
