“…The height of generative adults in South Africa has been established between 110 cm and 560 cm (MbaTha, 2016), in India up to 300 cm (srinivasan et al, 2007). The study on C. scoparius in Brazil has revealed that the average height of generative adults across populations range from 220 cm to 260 cm (león CoRDeRo et al, 2016). However, information on the variation in height of vegetative adults and juveniles from the native and invasive range is insufficient.…”

“…In other areas of Europe, C. scoparius is considered as alien species (Frodin & HeywooD, 1968;Gavrilova & Šulcs, 1999;saraTeanu et al, 2017). This species has been introduced and has become invasive in many regions of the world, including North America (Parker et al, 2002;oneto et al, 2010;Muir & va-Mosi, 2015), South America (isaacson, 2000;león CoRDeRo et al, 2016), South Africa (MkhiZe et al, 2013;MbaTha, 2016), Asia (suZuki, 2000;sriniva san et al, 2011), Australia and New Zealand (Wil-liaMs, 1981;Downey & sMiTh, 2000;sMiTh, 2000;Tran et al, 2016).…”

“…Studies on the life history, population structure and growth rate of invasive plant species provide important information about mechanisms of invasion and foresee control, management and eradication measures (sakai et al, 2001;raMula et al, 2008). Population structure of C. scoparius has been widely studied in the regions, where this species is highly invasive (Downey & sMiTh, 2000;sMiTh, 2000;Payn-teR et al, 2003;srinivasan et al, 2007) or its spread has just started, and further invasion is suspected (león CoRDeRo et al, 2016;MbaTha, 2016). Quite a few studies on the population have been performed in Europe, in the native range of this species (Payn-teR et al, 2000(Payn-teR et al, , 2003.…”

AbstractAlien invasive woody plant species, particularly those associated with nitrogen-fixing bacteria, are of special concern, because they may cause drastic changes in entire ecosystems. Although most of invasive species of Lithuania originate from other continents, one of these, Cytisus scoparius, is native to Europe. Fast spread of this species in Lithuania and its invasion to forest, coastal and continental sand, occasionally grassland habitats, stimulated us to study demographic structure of its populations. The aim of this research was to evaluate density, life stage and age structure of the populations, and to analyse relationships of the age of individuals with their life stages, height and stem diameter. Five populations were studied in the western, southern and eastern parts of Lithuania in July–August 2017. For the study, we selected stands of this species occupying at least 0.1 ha in a uniform habitat. We applied sampling plot method, and studied at least 100 individuals in each population, excluding seedlings. The age, life stage, height and stem diameter of 583 individuals were studied. The average density of individuals ranged between 5.15 individuals/m2 and 15.40 individuals/m2. Juvenile individuals reach the stage of vegetative adults on the second or third growth season, occasionally on the third year they reach even the stage of generative adults. The average age of juveniles was 1.10 years, of vegetative adults it was 2.99 years and 6.26 years of generative adults. The oldest generative individual was 28 years old. Linear regression analysis of the relationship between the plant age and the stem diameter revealed that the age predetermined the stem diameter variance by 81.0% in the studied populations. This study revealed that densities of C. scoparius individuals of all life stages in disturbed and undisturbed habitats were sufficient to sustain longevity and further expansion of populations. Therefore, appropriate measures for control and eradication of this species should be applied, particularly in the habitats of high conservation value.

“…The shrub scotch broom ( Cytisus scoparius (L.) Link) is native across central Europe and the British Isles but has been classified as an invasive species elsewhere (e.g. in the United States, Chile, Australia, New Zealand (Kang, Buckley, & Lowe, ), Brazil (Cordero, Torchelsen, Overbeck, & Anand, ), South Africa (Mkhize, Mhlambi, & Nanni, ) and India (Srinivasan, Shenoy, & Gleeson, ). Since its first record in southern Norway in 1876 (Blytt, ), it has spread northwards (Figure , see Appendix ) and has also increased in abundance in threatened habitats, such as endangered coastal heathlands (Lindgaard & Henriksen, ).…”

Aim: Biological invasions at the intracontinental scale are poorly studied, and intracontinental invasions often remain cryptic. Here, we investigate the recent range expansion of scotch broom (Cytisus scoparius) into Norway and clarify whether the genetic patterns indicate natural spread or human introduction. Furthermore, we investigate whether plants were moved within the native range and how this influences invasion success. We also infer the level and structuring of genetic diversity within and between the putative native and introduced range. Location: Europe.Methods: We analysed the chloroplast sequence variation in 267 scotch broom samples from its northern expansion front and from its native range across Europe, including herbarium samples dating back to 1835. For 37 populations, we analysed variation in nuclear single-nucleotide polymorphic markers to study gene flow and genetic diversity. Results:We identified 20 different haplotypes, which lacked spatial and temporal distribution patterns in the recent expansion range in Norway. They also mostly lacked patterns across the native European range of scotch broom. The genetic diversity of nuclear genomic SNP markers across populations in the introduced range was similar to that of populations in the native range, with limited differentiation among populations. Main conclusions: Scotch broom is alien to Norway and was introduced by humans on multiple occasions from diverse origins over a long period of time. High propagule pressure has probably maintained the high genetic diversity in the novel range through a combination of genetically diverse source populations and high gene flow among them. Within the native European range, our results suggest the presence of cryptic intraspecific admixture, most likely mediated by humans moving genotypes among the regions occupied by distinct native genotypes. Intracontinental invasions may easily go unnoticed and revealing these invasions and the factors driving them may be of great importance for the management of alien species.

The "broom" Cytisus striatus is cited for the first time for Argentina. This species coexists with the similar but more widespread "scotch broom", C. scoparius, frequent in disturbed habitats of Patagonia and temperate regions worldwide. So far, eight ruderal seed-producing individuals of C. striatus have been spotted in Patagonia. The morphological resemblance between C. striatus and C. scoparius, and the distance between both populations of C. striatus found in Argentina up to now (31 km) suggest that this species could be abundant in Andean regions of Patagonia. This paper provides a key for the identification of the brooms of Tribe Cytiseae present in Argentina.
