    1. Long-term changes in plant diversity of grasslands under agricultural and conservation management (pages 299–306)

      We compared long-term data (1976-2006) on agricultural and conservation grasslands (the Netherlands). While species richness still increased in conservation grasslands, no changes could be detected in agricultural grasslands after a past decrease. The floristic 'gap' between agricultural and conservation grasslands is still widening. Nature reserves become more and more important for the survival of plant species at the landscape level.

    2. The fencing paradigm in woodland conservation: consequences for recruitment of a semi-arid tree (pages 307–317)

      Fencing effectiveness for woodland conservation can be controversial. Fencing against cattle affected seedling emergence and survival, and consequently the stage structure of P. flexuosa woodlands. Fenced sites were dominated by adult trees, whereas grazed areas were dominated by seedlings and saplings. This study suggests that cattle are agents of seed dispersal of P. flexuosa, able to trigger its natural regeneration.

    3. Foliar N concentration and δ15N signature reflect the herb layer species diversity and composition in oak-dominated forests (pages 318–328)

      Jeňýk Hofmeister, Jan Hošek, František Bůzek and Jan Roleček

      Article first published online: 4 JAN 2012 | DOI: 10.1111/j.1654-109X.2011.01174.x

      We studied herb layer species composition, foliar nutrient concentrations and soil nutrient pools in nine oak forests. The herb layer species diversity and composition was significantly related to foliar N concentration, foliar δ15N signatures and soil N pool, respectively. These parameters may reliably indicate not only the N availability, but also predict consequences for the herb layer vegetation composition.

    4. Garden waste deposits as a source for non-native plants in mixed deciduous forests (pages 329–337)

      Hans-Peter Rusterholz, Dino Wirz and Bruno Baur

      Article first published online: 4 JAN 2012 | DOI: 10.1111/j.1654-109X.2011.01175.x

      Horticultural trade is an important pathway for un-intentional introductions of non-native plants in natural habitats. We showed that illegal garden waste dumping is a source for the establishment of non-native plant species in semi-natural deciduous forests in Switzerland. Furthermore, the dumping sites showed changes in soil characteristics.

    5. Interactions in tropical reforestation – how plant defence and polycultures can reduce growth-limiting herbivory (pages 338–348)

      Tara J. Massad

      Article first published online: 7 FEB 2012 | DOI: 10.1111/j.1654-109X.2012.01185.x

      This work reports results from a reforestation experiment testing the potential for plant chemistry and polycultures including well defended species to limit herbivory. Early herbivory reduced growth even after five years. The fastest growing species grew better in polyculture. Saponin defenses appeared to deter leaf-cutter ants. Overall, mixtures of fast-growing and well defended species may limit herbivory and enhance growth.

    6. Spatial pattern and composition of the Florida scrub seed bank and vegetation along an anthropogenic disturbance gradient (pages 349–358)

      Jennifer J. Navarra and Pedro F. Quintana-Ascencio

      Article first published online: 20 JAN 2012 | DOI: 10.1111/j.1654-109X.2011.01176.x

      The anthropogenic disturbances that altered vegetation distribution resulted in differences in seed bank spatial structure. This was most evident in scrub forbs which lacked a strong structural component in the degraded community but were aggregated and positively associate with above-ground microhabitats in the reference community. Amount of shrub cover may be influencing the association between the seed bank and vegetation.

    7. The potential for endozoochorous dispersal of temperate fen plant species by free-roaming horses (pages 359–368)

      Peter A. Stroh, J. Owen Mountford and Francine M.R. Hughes

      Article first published online: 1 DEC 2011 | DOI: 10.1111/j.1654-109X.2011.01172.x

      One-third of species recorded from a grazed temperate fen germinated from Konik dung samples. Seeds of germinants were significantly lighter, longer-lived, could tolerate higher nutrient levels and were produced in greater numbers than seeds of non-dispersed species. This was the first study to investigate endozoochorous dispersal of fen vegetation, and demonstrated the potential for endozoochory to complement alternative dispersal strategies.

    8. Initiation of microtopography in re-vegetated cutover peatlands: evolution of plant species composition (pages 369–382)

      Rémy Pouliot, Line Rochefort and Edgar Karofeld

      Article first published online: 4 NOV 2011 | DOI: 10.1111/j.1654-109X.2011.01164.x

      Thumbnail image of graphical abstract

      In peatland restoration or within the natural regeneration process of a peat extracted site, the typical alternation of hummocks and hollows returns more rapidly than typical species composition of each microstructure. All species able to tolerate the conditions prevailing on cutover peatland post-restoration or post-abandonment can contribute to the initiation microtopography, but could form atypical assemblages. Restoration steps and site conditions clearly have an influence.”

    9. Validation of a high-resolution, remotely operated aerial remote-sensing system for the identification of herbaceous plant species (pages 383–389)

      Fumiko Ishihama, Yasuyuki Watabe and Hiroyuki Oguma

      Article first published online: 2 FEB 2012 | DOI: 10.1111/j.1654-109X.2012.01184.x

      We applied a high-resolution remote-sensing system based on a lightweight (1.6 kg) radio-controlled helicopter (the “Falcon-PARS system”) to wetland vegetation. We obtained images with a spatial resolution of 1 cm and confirmed that we could identify major two herbaceous species from the images. Such a high-resolution remote-sensing system can be used as a non-destructive alternative to ground surveys.

    10. Predicting vascular plant richness patterns in Catalonia (NE Spain) using species distribution models (pages 390–400)

      Nora Pérez and Xavier Font

      Article first published online: 6 JAN 2012 | DOI: 10.1111/j.1654-109X.2011.01177.x

      This study provides a quantitative assessment of plant richness in Catalonia using standards of the nascent field of species distribution modeling for a total of 2738 species. Several components of the present manuscript could be helpful to others using the same techniques, including the relative evaluations of Kappa and TSS vs. the two components of disagreement, and use of COR in order to determine which of the techniques is most successful.

    1. A first formal classification of the Hardeveld vegetation in Namaqualand, South Africa (pages 401–431)

      Article first published online: 16 JAN 2012 | DOI: 10.1111/j.1654-109X.2011.01173.x

      For the first time, we provide a formal phytosociological classification of a section of the floristically highly diverse winter-rainfall desert Succulent Karoo in South Africa. The main floristic gradient was between the zonal vegetation of marginally saline soils (Hermannio trifurcae-Zygophylletea morgsanae cl. nov.) and the vegetation of highly saline soils, including areas of fossile termitaria (Didelto carnosae-Cephalophylletea inaequalis cl. nov.).

    2. Vegetation discontinuities and altitudinal indicator species in mountains of West Greenland: finding the best positions and traits to observe the impact of climate warming in the Arctic (pages 432–448)

      Birgit Jedrzejek, Birgit Drees, Fred J. A. Daniëls and Norbert Hölzel

      Article first published online: 15 FEB 2012 | DOI: 10.1111/j.1654-109X.2012.01186.x

      By spatially constrained clustering the study detects boundaries of vegetation belts in the inland of West Greenland at 400/450, 800/900 and 1175/1250 m a.s.l. These belts are characterised by 99 indicator species, plant functional types and plant distribution types. Numerous options for climate change monitoring are found in vegetation characteristics at the boundaries of these belts.
