Knowledge of the evolutionary history of plants that are ecologically dominant in modern ecosystems is critical to understanding the historical development of those ecosystems. Metrosideros is a plant genus found in many ecological and altitudinal zones throughout the Pacific. In the Hawaiian Islands, Metrosideros polymorpha is an ecologically dominant species and is also highly polymorphic in ...

Abstract Pollen types present in samples from corbiculae of Melipona capixaba (Moure and Camargo) (Hymenoptera: Apidae: Meliponina) worker bees were analyzed, as well as pollen samples from food pots inside the hives in three sites located at the bees' original habitat. The aim was to find out the sources used as a trophic resource by this species. The dominant pollen grains in the spectrum of ...

Plinia trunciflora is a Brazilian native fruit tree from the Myrtaceae family, also known as jaboticaba. This species has great potential by its fruit production. Due to the high content of essential oils in their leaves and of anthocyanins in the fruits, there is also an increasing interest by the pharmaceutical industry. Nevertheless, there are few studies focusing on its molecular biology an...

Research on allelopathic interactions can be useful in the search for phytotoxins produced by plants that may be employed as natural herbicides. The aim of this study was to assess the phytotoxic action of aqueous leaf extract of Blepharocalyx salicifolius, Myrcia multiflora, Myrcia splendens and Myrcia tomentosa on the germination and development of three weeds. The working hypothesis was that...

Chrysoporthe austroafricana (Cryphonectriaceae) is a damaging canker pathogen on Eucalyptus species in Southern Africa. Recent studies have shown that the fungus occurs on native Syzygium species and that it has apparently undergone a host range expansion from these native trees to infect non-native Eucalyptus. The aim of this study was to consider whether Chr. austroafricana and other Cryphone...

Este estudo analisa o camu-camu (myrciaria dubia; myrtaceae) como elemento da biodiversidade e recurso territorial mediado pela biotecnologia. Considerando as dimensões comerciais que fruto assume no estado do Amazonas, objetivo é analisar a vegetal um territorial. A investigação foi realizada período de 2014 2018 contou com levantamento bibliográfico sobre camu-camu, assim realização entrevist...

Austropuccinia psidii is an introduced plant pathogen known to have caused significant declines in populations of several Australian native Myrtaceae species. However, limited research has focused on the impacts communities aftermath its invasion. This study investigated relationship between disease impact level, species diversity, and functional richness seedling a wet sclerophyll forest south...

Abstract Understanding the long-term interactions between people and ecosystem in which they live is vital for informing present-day management plans. The use of pollen data palaeoecological reconstructions often limited by low taxonomic resolution pollen, reduces detail human influence on past vegetation. This true Australia where Myrtaceae, particularly Eucalyptus species, dominate landscape,...
