Most of the studies confirmed that plant species in the invasive range grow denser, taller, and produce more seeds than in the native range. ![]() Similarly, traits and ecological performance of species of North American origin have been compared with their invasive populations in Europe. Biological and ecological traits, morphological and genetic variation, or ecological performance of species native to Europe, Eurasia, or Asia have been usually studied and compared with their invasive populations in North America and Australia. Many studies have been dedicated to analysing various traits of species in their native and invasive ranges, frequently in different continents. The biological traits of plant species and their effect on mechanisms of invasions usually have been compared with native congeners, other phylogenetically related species, or similar non-invasive introduced species. ![]() High fecundity has been recognised as an important correlate of the invasiveness of various plant species because it predetermines high propagule pressure, which, in turn, facilitates the spread and further invasion. The potential fecundity in plants usually is estimated as the number of developed ovules, whereas realised fecundity is defined as the number of matured seeds or ratio between the number of ovules and matured seeds. Reproductive traits are among the most important characteristics defining the degree of success of a species’ establishment and further spread in a new area. Biological traits affect the invasion success at all life stages of an alien plant, from reproduction to dispersal, and the ability to compete with resident species. ![]() Species traits and their effects as determinants of potential invasiveness have been among the main puzzling questions of invasion ecology. Although many studies on other species have confirmed higher fecundity and overall better performance of plants in the invasive range than in the native range on other continents, this rule probably cannot be applied for intracontinental invasive species occurring in relatively close geographical regions to their native ranges. The results suggest that the number of ovules per pod, number of matured seeds, and the size of pods are related with the type of habitat and local environmental conditions in the habitat. The pod length was similar in both ranges, whereas the pod width was significantly greater in the invasive range than in the native range. scoparius in the native range was significantly higher than in the invaded range however, realised fecundity was not significantly different between the native and invasive ranges. scoparius in the invasive range in Lithuania, specifically in the southern part of the Boreal biogeographical region, outperform plants in the native range with regard to the analysed reproductive traits. The results of this study were not able to unambiguously confirm our hypothesis that C. scoparius in its native and invasive ranges, as well as relationships with the size of pods, habitat type, and how these traits vary at the same site in different years. The aim of this research was to reveal the potential and realised fecundity of C. We assumed that the same regularity exists in intracontinental invasions and thus investigated whether the reproductive traits of Scotch broom, Cytisus scoparius, perform better in the alien invasive range in Europe compared to its native range in the same continent. Studies on transcontinental invasions have revealed that invasive species perform better in the invasive range than in their native ranges. HACCP therefore means the hazard analysis and verification of all critical points at any stage during the preparation, processing, production, packaging, storage, transport, allocation, treatment and distribution of food.Reproductive traits are among the most important factors in determining the success of species establishment and invasion in a new area. The German definition of HACCP is therefore "Risiko-Analyse Kritischer Kontroll-Punkte". The three-way colour coding of our assortment helps the user to easily distinguish between different sources of contamination, application areas and cleaning zones and thus avoid cross-contamination.įield of Application: The abbreviation HACCP stands for "Hazard Analysis Critical Control Points". High-quality soft PBT bristles, stable plastic body with smooth surface, with hole for hanging up the productĪpplication area: The newly developed HACCP range has been produced in accordance with the specifications of the European Association of Brushware Producers. ![]()
