Yellow starthistle (Centaurea solstitialis L.) (YST) is an important invasive plant that infests millions of hectares in the western USA and Canada. Isolates of the exotic rust fungus Puccinia jaceae have been evaluated as a potential biological control for YST. The objectives of this study were to characterize isolates of P. jaceae by amplified fragment length polymorphic (AFLP) DNA analysis a...

In the current study, a field experiment was conducted to examine effects of litter on seedling emergence and early growth of four dominant weed species from the early successional stages of old field ecosystem and two perennial grassland species in late successional stages. Our results showed that increased litter cover decreased soil temperature and temperature variability over time and impro...

Background & Aim:The genus Salvia (commonly known as sage) is a broad genus belonging to the family Lamiaceae. This study is aimed at assessing the essential oil composition and antimicrobial activities of two Salvia species. Experimental: The chemical composition of the essential oils of Salvia officinalis L. and Sa...

Restoring habitats degraded by intensive agriculture is challenging, and the resulting communities often have lower quality host fewer species than reference ecosystems. To improve restoration outputs, we need to understand what limits both establishment performance of target in restored populations. In this study, focused on grassland with regional seeds compared two herbs, Betonica officinali...
