We used a long-term resurvey to assess change in moorland composition across Scotland between the 1970s and 2005. Species richness of moorlands increased due to expansion of grazing and pollution tolerant graminoids and generalist mosses, while specialist species declined. Climate, pollution and grazing all played significant roles in driving these changes.

Drivers of species richness and compositional change in Scottish coastal vegetation / Robin Pakeman in Applied Vegetation Science, vol. 20, n°2 (Année 2017)

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."

Linking functional traits and species preferences to species’ abundance and occupancy trends through time to identify habitat changes in coastal ecosystems / Robin Pakeman in Perspectives in Plant Ecology, Evolution and Systematics, vol. 27 (Août 2017)

Public [article]  inPerspectives in Plant Ecology, Evolution and Systematics > vol. 27 (Août 2017) . - pp. 35-44 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.
