Competitive interactions are mediated in a sex-specific manner by arbuscular mycorrhiza in Antennaria dioica
2017
Plants usually interact with other plants, and the outcome of such interaction ranges from facilitation to competition depending on the identity of the plants, including their sexual expression. Arbuscular mycorrhizal (AM) fungi have been shown to modify competitive interactions in plants. However, few studies have evaluated how AM fungi influence plant intraspecific and interspecific interactions in dioecious species. The competitive abilities of female and male plants of Antennaria dioica were examined in a greenhouse experiment. Females and males were grown in the following competitive settings: (i) without competition, (ii) with intrasexual competition, (iii) with intersexual competitio…
Hieracium madoniense(Asteraceae) – a new species from Sicily
2007
Abstract A new endemic species of Hieracium is described from the Madonie Mountains (northern Sicily). Named Hieracium madoniense, this new taxon is confined to the Rocca di Mele, along the borders of Fagus sylvatica woods, on carbonate substrate. Relationships with the closest taxa are discussed.
Hieracium pallidum subsp. aetnense (Asteraceae), a new subspecies from Sicily (Italy), with notes on the taxonomy of H. pallidum Biv.
2013
Hieracium pallidum subsp. aetnense Gottschl., Raimondo & Di Grist. is described and illustrated. H.pallidum is considered as an intermediate species between H. schmidtii and H. racemosum (“schmidtii>racemosum”) and is placed in H. sect. Grovesiana. By consequence, H.lanudae Gottschl. is transferred to H. pallidum as H. pallidum subsp. lanudae (Gottschl.) Gottschl., Raimondo & Di Grist. A key for the three recognised subspecies of H. pallidum is provided.
Rediscovery of Hieracium nebrodense (Asteraceae), a little-known endemic of Sicily (Italy)
2016
Hieracium nebrodense Tineo ex Lojac., a little-known endemic of Sicily, has been rediscovered from the type locality after almost two centuries since its first and only collection made in 1830 in the Madonie Mountains (N Sicily). In line with the treatment in ‘Med-Checklist 2’, it is reclassified as a subspecies of H. schmidtii. A new combination is made and a detailed description and illustration are provided.
