Asynchrony Drives Plant and Animal Community Stability in Mediterranean Coastal Dunes

Land use imperils plant and animal community stability through changes in asynchrony rather than diversity.

Human land use may detrimentally affect biodiversity, yet long-term stability of species communities is vital for maintaining ecosystem functioning. Community stability can be achieved by higher species diversity (portfolio effect), higher asynchrony across species (insurance hypothesis) and higher abundance of populations. However, the relative importance of these stabilizing pathways and whet...

Climate change drives a shift in peatland ecosystem plant community: implications for ecosystem function and stability.

The composition of a peatland plant community has considerable effect on a range of ecosystem functions. Peatland plant community structure is predicted to change under future climate change, making the quantification of the direction and magnitude of this change a research priority. We subjected intact, replicated vegetated poor fen peat monoliths to elevated temperatures, increased atmospheri...

Fire drives phylogenetic clustering in Mediterranean Basin woody plant communities

1. Many Mediterranean plant species persist after fire because their seeds are protected from the heat of the fire (e.g. hard-coated seeds, serotinous cones), thus permitting rapid post-fire recruitment. For simplicity, this trait will hereafter be called P and its two possible phenotypes P+ (seeder) and P– (non-seeder). 2. Because P+ appears in a narrow taxonomic spectrum and confers persisten...

Alien versus Native Species on Coastal Dunes in Central Italy. Plant Distribution and Traits

Herbivore preference drives plant community composition.

Herbivores are important drivers of plant species coexistence and community assembly. However, detailed mechanistic information on how herbivores affect dominance hierarchies between plant species is scarce. Here, we used data of a multi-site herbivore exclusion experiment in grasslands to assess changes in the cover of 28 plant species in response to aboveground pesticide. application. Moreove...
