Over the past 3 centuries, many species have been dispersed beyond their natural geographic limits by humans, but to our knowledge, reproductive isolation has not been demonstrated for such neo-allopatric species. We grew seeds from three species of Centaurea (Centaurea solstitialis, Centaurea calcitrapa, and Centaurea sulphurea) that are native to Spain and have been introduced into California...
گل گندم خاردار،centaurea calcitrapa l. (asteraceae) منشاء اروپا- آسیایی داشته و در مناطق وسیعی از آسیانه میانه و صغیر انتشار دارد. این گیاه در مراتع، چراگاه ها، کنار جاده ها، درون و حاشیه مزارع مشکلات زیادی را ایجاد کرده و در ایران به وفور یافت می شود. از اواخر اسفند سال 1392 تا مرداد ماه سال 1394 بررسی هایی به منظور شناسایی حشرات گیاه خوار مرتبط با گل گندم خاردار در نواحی مختلف اطراف ارومیه ان...
Use of focussed beam reflectance measurement (FBRM) for monitoring changes in biomass concentration.
The potential of focussed beam reflectance measurement (FBRM) as a tool to monitor changes in biomass concentration was investigated in a number of biological systems. The measurement technique was applied to two morphologically dissimilar plant cell suspension cultures, Morinda citrifolia and Centaurea calcitrapa, to a filamentous bacteria, Streptomyces natalensis, to high density cultures of ...
Differences in morphological or ecological traits expressed by exotic species between their native and non-native ranges are often interpreted as evidence for adaptation to new conditions in the non-native ranges. In turn this adaptation is often hypothesized to contribute to the successful invasion of these species. There is good evidence for rapid evolution by many exotic invasives, but the e...
An ethnobiological field study on food plants and medicinal foods traditionally consumed in three Arbëresh (ethnic Albanian) communities in northern Lucania (southern Italy) document approximately 120 botanical taxa used for these purposes. Non-domesticated food vegetables (liakra), mostly gathered during the spring season, play a central role as traditional functional food. Quantitative ethnob...
