Genista Monspessulana – Montpellier Broom, Cape Broom, Canary Broom
Application for WoNS candidacy Genista monspessulana – Montpellier Broom, Cape Broom, Canary Broom Contact: Ashley Millar - (08) 9334 0312; Department of Environment and Conservation (WA) October 2010 Introduction Genista monspessulana (L.) L.A.S.Johnson (Fabaceae), also known more commonly as Montpellier Broom, Cape Broom and Canary Broom, is a woody legume weed with significant current and potential impacts on forestry production, biodiversity of natural ecosystems, grazing systems, access to amenity areas and fire risk. Infestations occur in all temperate states of Australia, with particularly severe infestations in the Adelaide Hills, southern Tasmania, central and southern Great Dividing Range of NSW, central Victoria and south west WA. G. monspessulana was ranked 37th in the initial evaluation of weeds nominated for Weeds of Natural Significance (WONS) (Thorp and Lynch 2000), with a particularly high impact score due to its formation of dense, impenetrable thickets arising from a long-lived soil seed bank (source: Henry et al . 2010). Species description: G. monspessulana is an erect, perennial slender shrub which grows up to 5-6m. It has trifoliolate petiolate leaves which are more or less glabrous. This species has yellow flowers which are produced from August to January. G. monspessulana occurs in loamy soil through to lateritic and peaty sand and is commonly found along rivers and roadsides (Parsons and Cuthbertson 2001; FLORABASE DEC 2010). G. monspessulana is native to the Mediterranean region that has become established, and is considered a persistent and deleterious plant, in several other regions of the world, including the Americas, Australia and New Zealand. It is considered deleterious because of its ability to form dense almost mono-cultural stands, which replace and suppress native flora and economically valuable timber plants (Lloyd 2000). -

Nature Conservation 22: 169–190. https://doi.org/10.3897/natureconservation.22.19809 Abstract Isolated populations are usually subject to low fitness and reduced genetic diversity, both of which may negatively affect their survival and adaptive potential. Hence, these issues cannot be neglected when plan- ning conservation actions for isolated populations. The Italian population of Cistus laurifolius subsp. lau- rifolius is extremely isolated. Furthermore, it is affected by fragmentation, being constituted by a single larger subpopulation, surrounded by three much smaller subpopulations, a few hundred metres to a few kilometres apart. -

However, most reported evidences come from the study of polyploid systems and from crop species subjected to intense agronomic selection. In sharp contrast with polyploids, the evolutionary patterns of rDNA loci number in predominantly diploid lineages have received less attention. Most studies on rDNA loci changes lack explicit temporal frames, and hence their dynamics could not be assessed. Here, we assess the temporal patterns of rDNA site evolution in Cistus, an entirely diploid lineage. We assessed the number and chromosomal position of 45S rDNA loci in Cistus species using fluorescence in situ hybridization (FISH) and Ag- nucleolus organizing regions (Ag-NOR) staining. -
Endemism in Recently Diverged Angiosperms Is Associated with Chromosome Set Duplication
Endemism in Recently Diverged Angiosperms Is Associated With Chromosome Set Duplication Sara Villa University of Milan: Universita degli Studi di Milano Matteo Montagna Universita degli Studi di Milano Simon Pierce ( [email protected] ) Università degli Studi di Milano: Universita degli Studi di Milano https://orcid.org/0000-0003-1182- 987X Research Article Keywords: adaptative radiation, apo-endemics, diversity creation, genome doubling, neo-endemism, speciation mechanism Posted Date: June 17th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-550165/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/22 Abstract Chromosome set duplication (polyploidy) drives instantaneous speciation and shifts in ecology for angiosperms, and is frequently observed in neo-endemic species. However, the extent to which chromosome set duplication is associated with endemism throughout the owering plants has not been determined. We hypothesised that across the angiosperms polyploidy is more frequent and more pronounced (higher evident ploidy levels) for recent endemics. Data on chromosome counts, molecular dating and distribution for 4210 species belonging to the major clades of angiosperms were mined from literature-based databases. As all clades include diploid taxa, with polyploids representing a possible ‘upper limit’ to the number of chromosomes over evolutionary time, upper boundary regression was used to investigate the relationship between the number of chromosomes and time since taxon divergence, both across clades and separately for families, with endemic and non-endemic species compared. A signicant negative exponential relationship between the number of chromosomes and taxon age was 2 evident across angiosperm clades (R adj=0.48 with endemics and non-endemics considered together, 2 2 R adj=0.46 for endemics; R adj=0.44 for non-endemics; p ≤0.0001 in all cases), which was three times stronger for endemics (decay constant=0.12, cf. -
Germinative Response to Heat Treatments in Relation to Resprouting Ability
Journal of Ecology 2008, 96, 543–552 doi: 10.1111/j.1365-2745.2008.01359.x BurningBlackwell Publishing Ltd seeds: germinative response to heat treatments in relation to resprouting ability S. Paula and J. G. Pausas* Centro de Estudios Ambientales del Mediterráneo (CEAM), Charles R. Darwin 14, Parc Tecnològic, Paterna, València 46980, Spain Summary 1. In Mediterranean fire-prone ecosystems, plant species persist and regenerate after fire by resprouting, by recruiting new individuals from a seed bank (post-fire seeding), or by both resprouting and post-fire seeding. Since species with resprouting ability are already able to persist in fire-prone ecosystems, we hypothesize that they have been subjected to lower evolutionary pressure to acquire traits allowing or enhancing post-fire recruitment. Consequently, we predict that the germination of non-resprouters is more likely to be increased or at least unaffected by heat than the germination of resprouters. 2. To test this hypothesis we compiled published experiments carried out in Mediterranean Basin species where seeds were exposed to different heat treatments. We compared the probability of heat-tolerant germination (i.e. heated seeds had greater or equal germination than the control), the probability of heat-stimulated germination (i.e. heated seeds had greater germination than the control) and the stimulation magnitude (differences in proportion of germination of the heated seeds in relation to the untreated seeds, for heat-stimulated treatments) between resprouters and non-resprouters. 3. Non-resprouters showed higher probability of heat-tolerance, higher probability of heat- stimulation and higher stimulation magnitude even when phylogenetic relatedness was considered. Differences between life-forms and post-fire seeding ability do not explain this pattern. -

T. solaris-libera sp. nov. distinct morphology has been corroborated by its unique ITS-rDNA sequence. Macro and micro morphologic descriptions and phylogenetic analyses of ITS data for this species are pro- vided and discussed in relation to similar spiny-spored species in this genus and its putative host plant Tuberaria guttata. T. solaris-libera sp. nov. differs from other spiny-spored Terfezia species by its poorly delimited and thicker peridium and distinct spore ornamentation, and from all Terfezia spp. in it’s ITS nrDNA sequence. In comparison, T. fanfani usually reach large ascocarp dimensions, often with prismatic peridium cells, with olive green tinges in mature gleba and different spore ornamentation. T. lusitanica has a lighter yellowish and thinner peridium and a blackish gleba upon maturity, T. extremadurensis has a thinner well delimited peridium and Tuber-like gleba and T. -
