More than half of the alien plants naturalised in the arid southeast of the Iberian Peninsula could be invasive
<p>Data set of dthe paper "More than half of the alien plants naturalised in the arid southeast of the Iberian Peninsula could be invasive", by María J. Salinas-Bonillo, Alba Rodríguez-Rodríguez, M. Trinidad Torres-García, Miguel Cueto, and Javier Cabello.</p> <p>This data set includes the scores of the Australian and New Zealand Weed Risk Assessment (AWRA) (Pheloung et al. 1999) for 144 alien plant species naturalised in the arid southeast of the Iberian Peninsula, the geographical coordinates where they are recorded in the wild, and the bibliographic sources from which the information was obtained to answer the AWRA questions.</p>

Data from: Testing weed risk assessment paradigms: intraspecific differences in performance and naturalisation risk outweigh interspecific differences in alien Brassica
1.Risk assessments of alien species are usually conducted at species level, assuming that all individuals of a given species pose similar risks. However, this may not be the case if there is substantial within-species variation that could influence invasion success. 2.We used a seed addition experiment, comprising 25 taxonomically stratified varieties of three Brassica species introduced to roadside habitats in Canterbury, New Zealand, to quantify variation in performance among species, subspecies and varieties. We aimed to assess if species was the most appropriate taxonomic level at which to evaluate invasion risk. 3.Differences among varieties within species explained approximately 30 times more of the variation in performance (number of individuals/quadrat) than differences among species. Some of the variation among varieties was attributable to differences in seed viability. 4.Nevertheless, differences among taxonomic groups explained only 7% of the total variation in performance; 28% was attributable to differences among plots, reflecting broad-scale environmental variation, while 65% was attributable to differences among quadrats nested within plots, highlighting the importance of fine-scale variation in the availability of suitable microsites. 5.Policy Implications. Our seed addition experiment quantified variation in performance of 25 taxonomically stratified Brassica taxa introduced to roadside habitats. Varieties (nested within species) differed in performance far more than did species. This suggests risk assessments carried out at species level may overlook important subspecific variation in invasion risk. This is particularly true for conventionally bred and genetically modified species, which may contain taxa posing risks different to that at which the species is assessed. Consideration should be given to subjecting unassessed subspecies and varieties of plants to risk assessments similar to those applied to species.
FIGURE 7. Aloe mitriformis, a in An annotated catalogue of Aloe and Aloiampelos (Asphodelaceae subfam. Alooideae) naturalised and escaped in continental Portugal
FIGURE 7. Aloe mitriformis, a distinctive, South African representative of the genus, has long, creeping stems. It occurs naturally in the western parts of the Western Cape province and southern Northern Cape province, an area that experiences a Mediterranean-type climate, i.e., mild, wet winters and hot, dry summers, not unlike that prevalent over much of Portugal.

FIGURE 3. Two nothospecies with which Aloe maculata can be confused. A. Aloe ×schimperi [A. maculata × A. striata] cultivated in the Botanical Garden of the University of Porto, Porto. Note the distinctly pinkish leaf margins, a character inherited from A. striata. B. The flowers of A. ×schimperi lack the prominent basal swellings present in A. maculata. Both photographs A and B were taken on 22 December 2017. C. The rosettes of A. ×commutata [A. grandidentata × A. maculata] resemble those of A. maculata, but, as shown in D, its inflorescences are elongated (not capitate) and the flowers of this nothospecies, too, lack basal swellings, as found in A. grandidentata. Both photographs C and D were taken in the Huntington Botanical Gardens, San Marino, California, U.S.A., on 27 April 2011. All photographs by Gideon F. Smith.

FIGURE 4. Aloe ×nobilis in Portugal. A. The leaves are dark green, often more so when growing in shaded positions, as here. Leaf margins are concolorous and carry rather widely spaced, firm, white to slightly yellowish teeth, which gave rise to the English common name, golden tooth aloe. In full sun the leaves are usually distinctly reddish-infused. B. The cylindrical-conical, subdense racemes are up to 30 cm long. Photograph taken on 29 June 2012 of a plant cultivated in central Portugal. C. Aloe ×nobilis (in the container on the right) is commonly cultivated in Portugal, here in a domestic garden near the town of Serra de Santo António in the centre of the country.
