      The value of a monitoring program for the management of ecological resources, and interpretation of the role of environmental drivers, relies in its ability to detect change. Semboli et al. (2014, this issue) show that the simple act of repeated measuring significantly affects species composition in permanent tropical forest plots, but not species richness, species evenness or tree demography.

    1. Scale-dependent effects of grazing and topographic heterogeneity on plant species richness in a Dutch salt marsh ecosystem (pages 615–624)

      Jasper L. Ruifrok, Froukje Postma, Han Olff and Christian Smit

      Article first published online: 2 MAY 2014 | DOI: 10.1111/avsc.12107

      How does the interplay between grazing and topographic heterogeneity affect plant species richness at different spatial scales? We studied long-term grazed and ungrazed salt marshes and found positive effects of topographic heterogeneity at species richness at all spatial scales, and additive positive effects of grazing at most scales. The effectiveness of grazing was highest at low topographic heterogeneity.

    2. Impacts of temperature and water table manipulation on grassland phenology (pages 625–635)

      Christine Cornelius, Jan Heinichen, Matthias Drösler and Annette Menzel

      Article first published online: 9 MAY 2014 | DOI: 10.1111/avsc.12105

      This study focused on the question if reproductive phenology of different grassland species in peatland ecosystems changes with higher temperatures, increased water table level or with a combination of the two. For that, temperature was raised with open-top chambers (OTCs) and water table level was elevated using a pumping system. Phenological key phases were observed weekly with the BBCH code.

    3. Plant species richness and composition under different disturbance regimes in marginal grasslands of a Japanese terraced paddy field landscape (pages 636–644)

      Tomoyo F. Koyanagi, Susumu Yamada, Ken-ichi Yonezawa, Yoshiko Kitagawa and Kaoru Ichikawa

      Article first published online: 16 APR 2014 | DOI: 10.1111/avsc.12100

      Terraced paddy field landscapes consist of various types of marginal semi-natural grassland habitats maintained by different disturbance regimes. While some species occurred in all habitat types, habitat specialists characterized by specific plant functional groups (PFGs) responded to different disturbance regimes in each habitat type. Marginal semi-natural grassland habitats contribute to the overall biodiversity of terraced paddy field landscapes.

    4. Impact of management type and intensity on multiple facets of grassland biodiversity in the French Jura Mountains (pages 645–657)

      A survey of mesophilous grasslands in the French Jura Mountains revealed higher diversity in pastures than in grazed hayfields, whatever the diversity facet considered. Diversity metrics computed for taxonomic, phylogenetic and functional facets are negatively influenced by the defoliation intensity, while community-weighted mean trait values preferentially respond to the fertilization regime.

    5. Effects of grazing vs mowing on the functional diversity of sub-Mediterranean productive grasslands (pages 658–669)

      Andrea Catorci, Sabrina Cesaretti, Luca Malatesta and Federico M. Tardella

      Article first published online: 30 MAY 2014 | DOI: 10.1111/avsc.12103

      Understanding how different types of disturbance affect functional diversity and traits linked to competitive ability, resource acquisition and resistance strategies is vital to preserve the ecosystem functioning of semi-natural grasslands. In central Apennines, we found that grazing determines the dominance of traits related to resistance strategies, while late mowing increases species and functional diversities and the variety of functional traits.

      Life after fire: smoke and ash as germination cues in ericads, herbs and graminoids of northern heathlands (pages 670–679)

      Tessa Bargmann, Inger E. Måren and Vigdis Vandvik

      Article first published online: 2 MAY 2014 | DOI: 10.1111/avsc.12106

      Thumbnail image of graphical abstract

      Our study from a Norwegian semi-natural heathland shows that the fire cues ash and smoke promote germination in both graminoids and ericads. These responses are weakened when seed banks have been exposed to the cues in situ. The prevalence of positive fire cue responses underscores the importance of fire in heathlands, and of burning as a central tool for management.

    7. Invasive grasses change landscape structure and fire behaviour in Hawaii (pages 680–689)

      Lisa M. Ellsworth, Creighton M. Litton, Alexander P. Dale and Tomoaki Miura

      Article first published online: 26 MAY 2014 | DOI: 10.1111/avsc.12110

      Thumbnail image of graphical abstract

      We investigated evidence for the dominant paradigm that grass invasion and subsequent fire lead to widespread conversion from forest to grassland and to increased frequency and severity of wildfire. While our results show that grasslands are prone to more extreme fire behavior than forests, it was not always the case that increased flammability led to widespread increases in grassland cover.

    8. Does fire induce flowering in Brazilian subtropical grasslands? (pages 690–699)

      Alessandra Fidelis and Carolina Blanco

      Article first published online: 14 MAR 2014 | DOI: 10.1111/avsc.12098

      Fire is known to trigger flowering in different ecosystems. We aimed to analyze the effect of fire on flowering in plant communities in Brazilian subtropical grasslands, by establishing plots in sites with different fire histories and disturbance types. Fire stimulated flowering, with different responses between functional groups. However, fire season and frequency could be a limitation factor for some groups.

    9. Using a prescribed fire to test custom and standard fuel models for fire behaviour prediction in a non-native, grass-invaded tropical dry shrubland (pages 700–710)

      Andrew D. Pierce, Sierra McDaniel, Mark Wasser, Alison Ainsworth, Creighton M. Litton, Christian P. Giardina and Susan Cordell

      Article first published online: 3 JUN 2014 | DOI: 10.1111/avsc.12111

      We recorded fire behavior on at 40 ha prescribed fire in Hawai'i Volcanoes National Park and calculated rate of spread and flame length. We compared our observations to those predicted by a custom and several standard fuel models. Our results indicate that standard fuel models may be appropriate for use in Hawai'i, but custom models should be validated and used.

    10. Suitability and limitations of native species for seed mixtures to re-vegetate degraded areas (pages 726–736)

      Graça Oliveira, Adelaide Clemente, Alice Nunes and Otília Correia

      Article first published online: 20 FEB 2014 | DOI: 10.1111/avsc.12099

      Thumbnail image of graphical abstract

      A glasshouse experiment simulated hydroseeding of a Mediterranean quarry with six native species, either alone or in low- and high-density mixtures with other native species. They germinated, established and grew when sown alone, but performed poorly in mixtures, outcompeted by some co-seeded species. Therefore, future designs of hydroseeding mixtures must take the early seedling performance and species morphology into account.

    11. Does long-term monitoring of tropical forests using permanent plots provide unbiased results? (pages 737–743)

      Olivia Semboli, Denis Beina, Déborah Closset-Kopp, Sylvie Gourlet-Fleury and Guillaume Decocq

      Article first published online: 15 FEB 2014 | DOI: 10.1111/avsc.12097

      Even in observational studies conducted in the wild, visitors may unintentionally influence natural processes. Repeated visitation in tropical rain forest permanent plots altered neither the demography of trees, nor species richness and evenness, but species composition was significantly impacted, with more light-demanding trees and lianas, and shade-tolerant herbs of trampled soils, within trails and along trail edges than forest interiors.

    12. Combining ecological, social and technical criteria to select species for forest restoration (pages 744–753)

      Paula Meli, Miguel Martínez-Ramos, José María Rey-Benayas and Julia Carabias

      Article first published online: 27 JAN 2014 | DOI: 10.1111/avsc.12096

      Thumbnail image of graphical abstract

      We propose a framework to target species for their reintroduction in forest restoration projects. We targeted on species that (1) are naturally important in the reference forest; (2) are least likely to establish naturally; (3) show a wide regional distribution; (4) are socially accepted; and (5) are easy to propagate. Our framework is suitable for several stakeholders interested in forest restoration.

    13. Edge effects shape the spatial distribution of lianas and epiphytic ferns in Australian tropical rain forest fragments (pages 754–764)

      Ainhoa Magrach, Javier Rodríguez-Pérez, Mason Campbell and William F. Laurance

      Article first published online: 12 MAY 2014 | DOI: 10.1111/avsc.12104

      Our paper provides novel insights into the effects of forest fragmentation on inter-specific interactions between trees, lianas and epiphytic ferns in Australian tropical forests. We found that the capabilities of lianas to thrive in disturbed forests could be leading to the demise of epiphytic ferns, with cascading effects on many organisms whose existence depends on the presence of them.

    14. Mapping the local variability of Natura 2000 habitats with remote sensing (pages 765–779)

      Hannes Feilhauer, Carola Dahlke, Daniel Doktor, Angela Lausch, Sebastian Schmidtlein, Gundula Schulz and Stefanie Stenzel

      Article first published online: 10 JUN 2014 | DOI: 10.1111/avsc.12115

      The assessment of Natura 2000 habitats is time consuming. We thus test whether remote sensing may help to fulfill this task. Based on a combination of image data, field surveys, and empirical models we successfully mapped habitat types and their floristic variability in a mire complex. Subsequently, effects of the image characteristics on the mapping accuracy were analyzed.

    1. Vegetation diversity of mesic grasslands (Arrhenatheretalia) in the Iberian Peninsula (pages 780–796)

      Maria Pilar Rodríguez-Rojo, Federico Fernández-González, Lubomír Tichý and Milan Chytrý

      Article first published online: 23 JUN 2014 | DOI: 10.1111/avsc.12118

      Thumbnail image of graphical abstract

      We present a revised classification of Iberian mesic grasslands based on formal definitions and semisupervised classification. Soil reaction, summer aridity and altitude are the main ecological factors determining community diversity, also related to the biogeographic diversity in the Iberian Peninsula. We propose a list of diagnostic species for the alliances and the vegetation types included in the Arrhenatheretalia order.
