    1. Floods reduce the prevalence of exotic plant species within the riparian zone: evidence from natural floods

      Joe Greet, J. Angus Webb and Roger D. Cousens

      Article first published online: 29 JAN 2015 | DOI: 10.1111/avsc.12156

      We present evidence that flooding reduces the prevalence of terrestrial taxa (often exotic weeds) within riparian zones. Our study provides further evidence to support the use of managed floods to reduce the prevalence of terrestrial exotic taxa along regulated rivers. More generally, we demonstrate how natural experiments conducted around unregulated flow events can be used to inform environmental flow management.

    2. Recovery of plant diversity in restored semi-natural pastures depends on adjacent land use

      Marie Winsa, Riccardo Bommarco, Regina Lindborg, Lorenzo Marini and Erik Öckinger

      Article first published online: 13 JAN 2015 | DOI: 10.1111/avsc.12157

      Thumbnail image of graphical abstract

      We assessed how adjacent land use influences restoration success in previously abandoned semi-natural pastures. Our results indicate that restoration success, in terms of plant community recovery, is higher in pastures situated adjacent to an intact grassland that can act as a population source than in pastures surrounded by crop fields.

    3. Long-term vegetation dynamics (40 yr) in the Succulent Karoo, South Africa: effects of rainfall and grazing

      Margaretha W. van Rooyen, Annelise Le Roux, Conrad Geldenhuys, Noel van Rooyen, Nadine L. Broodryk and Helga van der Merwe

      Article first published online: 24 DEC 2014 | DOI: 10.1111/avsc.12150

      Thumbnail image of graphical abstract

      The vegetation change displayed elements of both equilibrium and non-equilibrium dynamics. The directional change evident in perennial species composition, supports the equilibrium concept whereby the negative changes induced by heavy grazing were partially reversed. The annual component showed no directional change, but displayed event-driven, nonequilibrium dynamics by fluctuating in reaction to the timing and quantity of rainfall.

    4. Human legacies differentially organize functional and phylogenetic diversity of urban herbaceous plant communities at multiple spatial scales

      Anna L. Johnson, Erica C. Tauzer and Christopher M. Swan

      Article first published online: 24 DEC 2014 | DOI: 10.1111/avsc.12155

      Thumbnail image of graphical abstract

      While many studies have described patterns of biodiversity at the scale of entire cities, we know much less about how processes of community assembly vary within cities. We surveyed plant diversity in vacant lots in Baltimore, MD, US, and demonstrate that human land-use legacies explain more variation in composition and diversity than environmental and spatial gradients in this system.

    5. Stand management to reduce fire risk promotes understorey plant diversity and biomass in a semi-arid Pinus halepensis plantation

      María N. Jiménez, Erica N. Spotswood, Eva M. Cañadas and Francisco B. Navarro

      Article first published online: 15 DEC 2014 | DOI: 10.1111/avsc.12151

      Thumbnail image of graphical abstract

      This paper shows how restoration thinning and vegetation treatments (clearing and ploughing) used to reduce fire risk can modify the understorey vegetation in pine plantations on previous croplands, increasing plant diversity and/or biomass. However, it does not lead to recruitment of species that are typical of the native forests, and stand management should be coupled with active restoration techniques.

    6. Both farming practices and landscape characteristics determine the diversity of characteristic and rare arable weeds in organically managed fields

      Roser Rotchés-Ribalta, José Manuel Blanco-Moreno, Laura Armengot, Lourdes Chamorro and Francesc Xavier Sans

      Article first published online: 9 DEC 2014 | DOI: 10.1111/avsc.12154

      Thumbnail image of graphical abstract

      Characteristic arable weeds have dramatically declined in arable cropping systems due to land-use management and changes in agricultural landscape. The decline of some species has been so sharp that they have become rare. Our broad survey on organic fields reflects that adequate fertilization and the presence of autumn-sowing cereals in the crop rotation enhance their persistence.

    7. Managing cattle grazing and overstorey cover for the conversion of pine monocultures into mixed Mediterranean woodlands

      Yagil Osem, Tom Fogel, Yossi Moshe and Shlomo Brant

      Article first published online: 8 DEC 2014 | DOI: 10.1111/avsc.12152

      Thumbnail image of graphical abstract

      We investigated the effects of cattle grazing and overstory cover on natural regeneration in east Mediterranean pine (Pinus brutia) plantations. Pine recruitment and sapling growth were significantly promoted by grazing exclusion and overstory thinning. Recruitment of broadleaved tree species was only little affected by grazing and overstory cover but their growth was significantly enhanced following grazing exclusion and overstoy thinning.

    8. Grassland restoration by seeding: seed source and growth form matter more than density

      Emer A. Walker, Julia-Maria Hermann and Johannes Kollmann

      Article first published online: 8 DEC 2014 | DOI: 10.1111/avsc.12153

      Thumbnail image of graphical abstract

      This field experiment tests effects of seed source (regional wild vs cultivar) and seeding density of one matrix grass and three forb species, and of grass growth form, on establishment and flowering of target species and suppression of invasive species on calcareous gravel. Cultivars tend to flower more, but establishment and invasive suppression is better in regionals – here, especially tussock grasses.

    9. Soil mutualists modify priority effects on plant productivity, diversity, and composition

      Laura A. Burkle and R. Travis Belote

      Article first published online: 21 NOV 2014 | DOI: 10.1111/avsc.12149

      Thumbnail image of graphical abstract

      In a manipulative mesocosm experiment, mycorrhizal fungi modified priority effects and productivity-diversity relationships, suggesting that pioneer species interact with soil mutualists to govern diversity, community composition, and ecosystem function. Negative effects of a non-native pioneer grass on the colonizing community were ameliorated by mycorrhizal supplements, suggesting that mycorrhizal amendments may enhance diversity of degraded sites in restoration projects.

    1. Impact of ungulate exclusion on understorey succession in relation to forest management in the Intermountain Western United States

      Burak K. Pekin, Bryan A. Endress, Michael J. Wisdom, Bridgett J. Naylor and Catherine G. Parks

      Article first published online: 1 NOV 2014 | DOI: 10.1111/avsc.12145

      Thumbnail image of graphical abstract

      Our study explores plant community responses to ungulate grazing with regards to forest management history. Trajectories of vegetation composition and diversity differ strongly in grazed versus ungrazed sites following stand thinning and prescribed fire. Grazing effects are less pronounced in later seral stages found on unmanaged sites.

    1. Small wetlands are critical for safeguarding rare and threatened plant species

      Sarah J. Richardson, Richard Clayton, Brian D. Rance, Hazel Broadbent, Matt S. McGlone and Janet M. Wilmshurst

      Article first published online: 30 OCT 2014 | DOI: 10.1111/avsc.12144

      Thumbnail image of graphical abstract

      Rare species are often used to prioritise sites for conservation management, yet it is unclear whether this approach yields co-benefits for all biodiversity and ecosystem properties. Using wetland plants from southern New Zealand, we found no evidence that preserving sites with rare species safeguarded community types, rare environments or large wetlands. Small wetlands were critical for safeguarding rare species.

    1. Landscape context in colonization of restored dry grasslands by target species

      Karel Prach, Karel Fajmon, Ivana Jongepierová and Klára Řehounková

      Article first published online: 21 OCT 2014 | DOI: 10.1111/avsc.12140

      Thumbnail image of graphical abstract

      We consider the strongest point of our paper is the large-scale of the study. We are not aware of any such extensive restoration of grasslands using a species-rich regional seed mixture. The restoration was organized by our colleague Ivana Jongepierová (see photo) and without her enthusiasm the restoration, and thus this study, could not be possible to realize.

    2. Climatic characterization of forest zones across administrative boundaries improves conservation planning

      Heather A. Klassen and Philip J. Burton

      Article first published online: 21 OCT 2014 | DOI: 10.1111/avsc.12143

      Thumbnail image of graphical abstract

      The full climatic niche for British Columbia's Coastal Douglas-fir forest zone is determined from its mapped distribution and georeferenced plot data in the neighbouring USA. A new subzone is characterized, and the potential distribution of the extended zone is projected under a changing climate to identify climate refugia. For sensitive ecosystems with multi-jurisdictional distributions, this approach helps focus conservation efforts.

    3. Changes in landscape composition of differently irrigated hay meadows in an arid mountain region

      Eliane Riedener, Ramona L. Melliger, Hans-Peter Rusterholz and Bruno Baur

      Article first published online: 21 OCT 2014 | DOI: 10.1111/avsc.12141

      Thumbnail image of graphical abstract

      We examined consequences of a change in irrigation technique (from traditional flooding to sprinkler irrigation) for the plant diversity of species-rich hay meadows and the surrounding landscape in an arid Swiss mountain region. The installation of sprinklers was associated with a homogenisation of the landscape. The highly structured surroundings are important for the conservation of the meadows' plant diversity.

    4. Three decades of vegetation changes in peatlands isolated in an agricultural landscape

      Salomé Pasquet, Stéphanie Pellerin and Monique Poulin

      Article first published online: 21 OCT 2014 | DOI: 10.1111/avsc.12142

      Thumbnail image of graphical abstract

      We examined vegetation changes over three decades in temperate peatlands isolated in agricultural landscapes and affected by a recent fire. Results showed noteworthy species turnover with a significant forest cover increase in margins and post-fire succession through non-peatland to peatland species in the centre. The broader implication is that peatland conservation in highly modified landscapes must be linked to restoration.

    5. Vegetation dynamics of managed Mediterranean forests 16 yr after large fires in southeastern Spain

      Raquel Alfaro-Sánchez, Raúl Sánchez-Salguero, Jorge De las Heras, Enrique Hernández-Tecles, Daniel Moya and Francisco R. López-Serrano

      Article first published online: 15 OCT 2014 | DOI: 10.1111/avsc.12137

      Thumbnail image of graphical abstract

      Early treatments applied to post-fire regenerated P. halepensis forests of southeastern Spain, including removal of the understorey vegetation and thinning, are a suitable option to reduce fire hazards in the short term and to enhance the diversity indices when applied to very high tree density post-fire regenerated stands, even in areas with very limited resources such as semi-arid ecosystems.

    6. Land-use history and an invasive grass affect tallgrass prairie sedge community composition

      Devan Allen McGranahan, David M. Engle, John T. Mulloy, James R. Miller and Diane M. Debinski

      Article first published online: 30 SEP 2014 | DOI: 10.1111/avsc.12136

      Thumbnail image of graphical abstract

      Little research has reported on the abundance and diversity of upland grassland sedges (Cyperaceae). We found 21 species across five genera. Sedges averaged 23% of total plant cover in intact tallgrass prairie. Sedges provide substantial early-season forage for grazers. Although community composition varied with land-use history and across levels of an invasive species, diversity was unaffected by grazing history.

    7. Post-ranching tree–grass interactions in secondary Acacia zanzibarica woodlands in coastal Tanzania – an experimental study

      Roland Cochard, Peter J. Edwards and Ewald Weber

      Article first published online: 17 SEP 2014 | DOI: 10.1111/avsc.12134

      Thumbnail image of graphical abstract

      When clearings were created in secondary Acacia zanzibarica woodlands, resprouting occurred from acacia stumps and roots, and many seedlings established. The absence of ungulate grazing allowed prolific grass growth and associated competition for water. Acacia seedlings were killed and sprout densities decreased in the dry season, partly as a result of fires. Woodlands did not readily regenerate; clearings remained.

    8. Changes in the fruiting landscape relax restrictions on endozoochorous tree dispersal into deforested lands

      Daniel Martínez and Daniel García

      Article first published online: 17 SEP 2014 | DOI: 10.1111/avsc.12135

      Thumbnail image of graphical abstract

      Passive reforestation is scarce and spatially constrained, as few tree seeds arrive far from remnant forest. We show how dynamism in fruiting landscapes can relax restrictions on seed dispersal into deforested areas. An increase in fruit production by isolated trees remaining within those areas influenced frugivore activity resulting in more seeds dispersed out of the forest and further from it.

    9. Long-term climate forcings to assess vulnerability in North Africa dry argan woodlands

      Francisca Alba-Sánchez, José Antonio López-Sáez, Diego Nieto-Lugilde and Jens-Christian Svenning

      Article first published online: 15 SEP 2014 | DOI: 10.1111/avsc.12133

      Thumbnail image of graphical abstract

      North African dry woodlands constitute Mediterranean climatic-ecotone ecosystems of vital importance for human livelihoods and local biodiversity. To improve the basis for managing these key ecosystems, we have selected a Tertiary relict woodland (Argania spinosa) in order to clarify the sensitivity to long-term climate change (the present, the past glacial-interglacial cycle, and under future scenarios).

    10. The rise and fall of Leptospermum laevigatum: plant community change associated with the invasion and senescence of a range-expanding native species

      Luke S. O'Loughlin, Peter T. Green and John W. Morgan

      Article first published online: 8 SEP 2014 | DOI: 10.1111/avsc.12131

      Thumbnail image of graphical abstract

      Shrub invasions often alter ground layer vegetation but the permanence of these changes is sometimes unclear. The study of plant community patterns across a chronosequence of Leptospermum laevigatum invasion and senescence found that canopy gaps promoted higher species diversity and created a community composition more similar to an uninvaded state. Gaps provided increased habitat heterogeneity in an otherwise uniform landscape.
