[Thèmes] PâturageMots-clés : acidification eutrophisation Écosse succession changement de la végétation Résumé : "A quadrat-based revisitation survey was used to identify drivers of species losses and gains in Scottish sand dunes. Richness losses in eastern Scotland were driven by acidic deposition and reduced grazing. Species richness changes were neutral/positive where sand dune and machair habitats remained part of agricultural systems on the Hebridean islands."

Titre : Linking functional traits and species preferences to species’ abundance and occupancy trends through time to identify habitat changes in coastal ecosystems Type de document : texte imprimé Auteurs : Robin Pakeman, Auteur ; Richard Hewison (Richard Langwell), Auteur ; Rob Lewis (Rob J.), Auteur Année de publication : 2017 Article en page(s) : pp. 35-44 Langues : Anglais (eng) Résumé : "Coastal habitats are rich in biodiversity and provide highly valued ecosystem services. However, they are subject to many environmental drivers that can have severe impacts on these inherently fragile ecosystems. A resurvey approach was used to assess changes in species’ abundances and occupancy on sand dunes and machair in Scotland, UK to assess how this could impact on this set of habitats. These were assessed to see if increasers and decreasers shared common trait values, if trends were similar to other terrestrial habitats and if responses to environmental drivers were modulated by traits. In general, there has been a shift towards taller species with more exploitative growth forms and an increase in indicators of unfavourable habitat condition according to criteria for assessing sites designated for nature protection as part of the EU Natura 2000 network, particularly tall grasses characteristic of nutrient …' Type de publication : périodique Référence biblio : Pakeman R., Hewison R., Lewis R., 2017 - Linking functional traits and species preferences to species’ abundance and occupancy trends through time to identify habitat changes in coastal ecosystems.

Titre : The epiphytic bryophyte community of Atlantic oak woodlands shows clear signs of recovery following the removal of invasive Rhododendron ponticum Type de document : texte imprimé Auteurs : Janet Maclean, Auteur ; Ruth Mitchell, Auteur ; David Burslem, Auteur ; Jeanette Hall, Auteur ; Robin Pakeman, Auteur ; David Genney, Auteur Année de publication : 2017 Article en page(s) : pp. 96-104 Langues : Anglais (eng) Résumé : "Increased awareness of the negative impacts of invasive non-native species has led to a rapid increase in clearance programs around the world. One of the main goals of clearance is the restoration of native communities that were present pre-invasion. Little monitoring is typically carried out, however, to verify that native communities return without further management intervention in the years following invasive species removal. We investigated whether the epiphytic plant community of Atlantic oak woodlands, which principally consists of bryophyte species, returned after up to thirty years of recovery following the removal of the invasive non-native shrub Rhododendron ponticum. This community is of international conservation value and is particularly threatened by invasive Rhododendron. We revealed that the epiphytic plant community was able to recover effectively in sites that had been clear from Rhododendron for over fifteen years. This recovery included several species of particular conservation interest with highly restricted European distributions (i.e. ‘Atlantic species’ such as Plagiochila heterophylla). Total cover and species richness both returned to similar or even higher levels to those found in uninvaded control plots by fifteen or more years following clearance, despite being highly reduced within dense Rhododendron thickets. Overall community composition also recovered to resemble uninvaded control plots in the years following Rhododendron removal. These findings present an encouraging message that at least some native communities can return naturally in the years following invasive species removal and may not require further management interventions to speed their return."
