Much of the annual growth of the heather was regularly consumed by this grazing, but no burning occurred to remove heather biomass. Two sites were on acidic base-poor soils and had only minor cover of grasses and herbs, their vegetation having most affinity to H10 heath in the National Vegetation Classification of British plant communities. The other two sites were on more base-rich soils, and grasses and herbs had substantial cover; their vegetation showed most affinity to NVC CG11a grassland. One of the latter sites lies at 700 m and Calluna grew poorly being close to its altitudinal limit; the other three sites were at lower altitude and Calluna grew strongly creating dense swards. Over the 43–44 years of observation Calluna increased moderately in height but many subordinate higher plants declined in cover, as measured by point-quadrat recording. Bryophytes increased at three sites largely due to substantial gains of Hylocomium splendens, but other pleurocarpous mosses suffered some declines. At the three lower-altitude sites species number fell by 20–35% between the first and last recordings, but at the high-altitude site there was negligible change in species number. The main drivers of change were the grazing received and the performance of Calluna, and no evidence was found of species composition reacting to climate change or nitrogen deposition. To maintain diversity, timely burning is recommended.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"24 1","pages":"31 - 42"},"PeriodicalIF":0.0,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79114379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its populations are characterised by low census size and strong fragmentation. Uni- and bi-parentally inherited markers were used to study the regional genetic make-up of the species. We analysed 31 samples from six different sites across south Wales and south-west England, spanning the whole putative natural occurrence in Britain. Genetic diversity in the entire British population (all six sites) was unexpectedly high, with 2.912 alleles per locus (nuclear DNA) and three different maternal lines (chloroplast DNA). In contrast, diversity within sites was low as we found identical multilocus microsatellite genotypes in five out of the six sampled locations. Finally, comparison with a pan-European dataset of S. domestica revealed a close association between British and French populations rather than with populations from the Mediterranean area or Balkan Peninsula. The putative native status of S. domestica in the British Isles is discussed based on our population genetic results as well as on ecological and historical aspects.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"8 1","pages":"21 - 30"},"PeriodicalIF":0.0,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77258638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease may potentially kill large numbers of Fraxinus excelsior (ash) trees in infected areas. Ash woods tend to be relatively rich in vascular plants and the composition of the flora might be expected to change if F. excelsior is lost and the environmental conditions (levels of shading, nutrient addition/recycling) change. We explore this possible scenario for the UK, using the floristic tables from the UK National Vegetation Classification (NVC) to identify for analysis eight ash-constant woodland types (where F. excelsior is a constant species) and four woodland types where F. excelsior is a frequent species. From these 12 communities, we identify 58 ground flora species that may be described as being ash woodland-associated species, including five species with some level of conservation protection. Changes in the ground flora are likely to be driven initially by increased light due to the opening up of the canopy as F. excelsior is lost, followed by increases in the shrub layer and eventually a closing of the canopy by other tree species. Using existing knowledge of plant species traits and habitat preferences (regeneration strategies, Ellenberg light values and Grime CSR scores) and community composition from NVC tables, we predict how the vascular plant community of ash-woodlands may change over time if F. excelsior is lost. We show that ash dieback could drive substantial changes in the ground flora community composition of currently ash-dominated woodlands.","PeriodicalId":19229,"journal":{"name":"New Journal of Botany","volume":"134 1","pages":"15 - 2"},"PeriodicalIF":0.0,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77374693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cheek","doi":"10.1080/20423489.2016.1167446","DOIUrl":"https://doi.org/10.1080/20423489.2016.1167446","url":null,"abstract":"Pearman & Rumsey (2004) and Stace et al. (2015) give excellent and detailed accounts of the hybrid between Drosera rotundifolia L. andD. intermediaHayne, referring to it asD. x belezeana E.G. Camus. Both state that the several records reported by Webb (reported in Stace, 1975) are erroneous or unsubstantiated and the only confirmed site (in Great Britain and Ireland) is at Godlingston Heath, Dorset. They go on to cite evidence that in Germany and Austria, voucher specimens of the hybrid have also often proved to be misidentified (e.g. T. Huntke in Stace et al., 2015). Through the availability of digital images on the internet, it has come to light recently that the type of D. x belezeana, from France, was also misidentified and is in fact merely D. rotundifolia (Schlauer cited in Bailey (2015)), which I have confirmed. For this reason a new name was coined for the hybrid, Drosera x eloisiana T. S. Bailey, based on a specimen that Bailey collected at Godlingston Heath (Bailey, 2015). The new name is already registered on Index Kewensis and the International Plant Names Index (IPNI, continually updated). Looking at the protologue ofD. x belezeana (Camus, 1891) and at specimens purported to be this hybrid from the type locality which are housed at P (Laboratoire Phanerogamique, Muséum Nationale D’Histoire Naturelle, Paris), now available on the internet, it is clear that they are either D. rotundifolia or D. intermedia or, sometimes, both species on one sheet, but none is the actual hybrid. In fact there is no evidence that this hybrid has ever been recorded in France! A likely explanation, it seems tome, is that Camus (1891), in his paper recording the Drosera in the area around Paris, which included D. x obovata Mert. & W.D.J. Koch (Drosera anglica Hudson ×D. rotundifolia), had decided that D. rotundifolia ×D. intermediawas also a logical likelihood since both parents occur there together. Could it be that he had, in looking for specimens to fulfil his hunch, merely been victim to his own wishful thinking? Presumably Camus had to guess at what the hybrid might look like, since he had never seen it, and he evidently guessed wrong! The hybrid has suborbicular to obovate blades which are always longer than broad (in D. rotundifolia and in the protologue of D. belezeana, the blades are broader than long); in the hybrid the leaves are elevated above the horizontal by 45°–80° (in D. rotundifolia and D. belezeana they are horizontal); in the hybrid there are 8–12 leaves per rosette (in D. rotundifolia and D. belezeana only 4–6).
