“…In the last decade a considerable effort has been made to elucidate the role of soil fauna and especially of plantparasitic nematodes in the functioning and dynamics of vegetation in coastal dunes (Van der Putten et al, 1990;Brinkman et al, 2005;. Although some members of the genus Pratylenchus were identified as key species involved in the biotic interactions occurring in the rhizosphere of A. arenaria in coastal dunes (Van der Putten et al, 1990;Seliskar & Huettel, 1993), the distribution and diversity of Pratylenchus species in the natural range of distribution of the host plant was unknown.…”

The distribution and diversity of Pratylenchus species associated with Ammophila arenaria was investigated in its natural range of distribution. Twelve localities with vigorous stands of A. arenaria along the European Atlantic and Mediterranean coasts were sampled. The populations were identified based on morphology and morphometrics, and further characterised based on sequences of the rDNA D2D3 region. Pratylenchus spp. were present in all of the sampled sites. A total of 19 populations were detected belonging to Pratylenchus dunensis, P. brzeskii, P. pratensis or P. penetrans. Pratylenchus dunensis was widely distributed from Blakeney Point (UK) to Comporta (Portugal). Pratylenchus brzeskii was found in South European localities along the Atlantic coast and also in the Mediterranean region. Pratylenchus pratensis was found associated with A. arenaria for the first time and occurred at different locations along the Atlantic coast. Pratylenchus penetrans was only detected in Biarritz (France). The P. dunensis populations from the south west Iberian Peninsula differed from the original P. dunensis description and showed two incisures on the lip region instead of one. Pratylenchus brzeskii populations did not vary morphologically from the original descriptions; however, the range of their morphometrical characters was wider than that of the type population. The D2D3 rDNA region revealed large interspecific and low intraspecific variation, supporting the morphological identification. The phylogenetic relationships of the populations with respect to other species of the genus were inferred from partial sequences of the rDNA and positioned P. dunensis within the same group as P. convallariae, P. penetrans and P. fallax

“…The growth functions defi ne the different types of vegetation in the model environment, refl ecting levels of tolerance to burial and/or erosion, and peak annual growth rates. For coastal dune environments we use two rudimentary functions (Figure 1) that represent: (i) pioneer vegetation species such as marram grass (Ammophila) that require fresh input of sediment for optimum growth (Van der Putten, 1993), and (ii) more conservative woody shrub species (successional, late-sere, or semi-climax) with slower growth rates, such as creeping willow (Salix). While there is a body of literature on the effects of sand burial on a few select plant species (e.g.…”

Cellular automaton modelling for the simulation of dune fi eld formation and evolution has developed progressively in aeolian geomorphology in the last decade or so. A model that incorporates the effects of vegetation and its interactions with geomorphic landscape development -the Discrete Ecogeomorphic Aeolian Landscapes (DECAL) model -can replicate a number of important visual and qualitative aspects of the complex evolution of aeolian dune landscapes under the infl uence of vegetation dynamics in coastal environments. A key challenge in this research area is the analysis and comparison of both simulated and real-world vegetated dune landscapes using objective and quantifi able principles. This study presents a methodological framework or protocol for numerically quantifying various ecogeomorphic attributes, using a suite of mathematically defi ned landscape metrics, to provide a rigorous and statistical evaluation of vegetated dune fi eld evolution. Within this framework the model parameter space can be systematically explored and simulation outcomes can be methodically compared against real-world landscapes. Based on a simplifi ed scenario of parabolic dunes developing out of blow-outs the resulting dune fi eld realizations are investigated as a function of variable growth vigour of two simulated vegetation types (pioneer grass and successional woody shrub) by establishing a typological phase-diagram of different landscape classes. The set of simulation outcomes furthermore defi nes a higher-dimensional phase-space, whose axes or dimensions can be interpreted by analysing how individual ecogeomorphic landscape metrics, or state variables, contribute to the data distribution. Principal component analysis can reduce this to a visual three-dimensional (3D) phase-space where landscape evolution can be plotted as time-trajectories and where we can investigate the effects of changing environmental conditions partway through a simulation scenario. The use of landscape state variables and the construction of a 3D phase-space presented here may provide a general template for quantifying many other eco-geomorphic systems on the Earth's surface.

“…This plant species is very tolerant to sand burial and promotes dune formation by accumulating wind-blown sand. Ammophila arenaria also develops extensive root systems which are colonized by both mutualistic and parasitic organisms [8,21,29]. Several previous studies have shown the presence of AMF associated with A. arenaria [13,14,21,23].…”

with time and location. A clear peak of sporulation in autumn was found for three of the northern sites, but no pattern was detected in the southern sites. Root colonisation showed no seasonal pattern, despite differences between sampling times. Both hyphal coils and arbuscules were observed inside the roots, indicating colonisation by more than one AMF species. No correlation was found between root colonisation and spore number, or between AMF abundance and soil fertility. We conclude that: (a) spore production is driven by climatic conditions in the studied northern sites and by plant phenology in the studied southern sites; and that (b) root colonisation is independent of climate, phenology and soil fertility in the studied locations.
