Opportunities to directly study infrequent forest disturbance events often lead to valuable information about vegetation dynamics. In mesic temperate forests of North America, stand-replacing crown fire occurs infrequently, with a return interval of 2000-3000 years. Rare chance events, however, may have profound impacts on the developmental trajectories of forest ecosystems. For example, it has...

Allelopathic plants are important resources for the discovery of bioherbicides. Rosebay willowherb [Chamaenerion angustifolium (L.) Scop. syn. Epilobium L.] widely distributes in Western Asia, Europe, and North America, behaves as a dominant species within community due to production substances that restrict growth other plants. This study aims at investigating allelopathic potential rosebay by...

BACKGROUND: The ability of plants to adapt oxygen deficiency is associated with the presence various adaptations, many which are mediated by significant changes metabolism. These allow resistant wetland grow even in oxygen-deficient environment.
 AIM: aim study was carry out metabolic profiling leaves species Epilobium palustre and hirsutum, mesophyte angustifolium order identify most char...
