Data from: Sediment availability provokes a shift from Brownian to Lévy-like clonal expansion in a dune building grass.
<p>This dataset accompanies the manuscript: 'Sediment availability provokes a shift from Brownian to Lévy-like clonal expansion in a dune building grass.' Reijers et al., accepted at Ecology Letters</p> <p>Abstract</p> <p>In biogeomorphic landscapes, plant traits can steer landscape development through plant-mediated feedback interactions. Interspecific differences in clonal expansion strategy can therefore lead to the emergence of different landscape organizations. Yet, whether landscape-forming plants adopt different clonal expansion strategies depending on their physical environment remains to be tested. Here, we use a field survey and a complementary mesocosm approach to investigate whether sediment deposition affects the clonal expansion strategy employed by dune-building marram grass individuals. Our results reveal a consistent shift in expansion pattern from more clumped, Brownian-like, movement in sediment-poor conditions, to patchier, Lévy-like, movement under high sediment supply rates. Additional model simulations illustrate that the sediment-dependent shift in movement strategies induces a shift in optimization of the cost-benefit relation between landscape engineering (i.e. dune formation) and expansion. Plasticity in expansion strategy may therefore allow landscape-forming plants to optimize their engineering ability depending on their physical landscape.</p> <p>Methods</p> <p>Data stored in this repository are collected during both a field survey and a one-year mesocosm experiment in which we measured traits from marram grass (<em>Ammophila arenaria</em>) growing in conditions with either low or high sediment availability or deposition. Focus was primarily on spatial shoot organization and the step size distribution of the distances between shoots as a proxy for clonal expansion strategy. These shoot coordinates were extracted from still images (photos from the field survey are included in the repository, images from the mesocosm experiment are available upon request) and distances were calculated using a nearest neighbour connecting algorithm. Detailed description of these methods can be found in the accompanying publication (Reijers <em>et al.</em> <em>Ecology Letters</em>) or in a previously published method protocol (Reijers & Hoeks, 2019 <em>Protocol Exchange)</em>. In addition we measured several plant growth related parameters such as: shoot length, shoot diameter, rhizome depth and leaf C:N ratio for the plant sampled during the field survey and shoot height, shoot numbers, shoot growth and leaf C:N ratio for the plants growing in the mesocosm experiment. Next to plant related data we measured several environmental characteristcs in the field including grain size, elevation, plant available nitrogen, organic matter, distance to sea and sediment deposition. For the mesocosm experiment we measured soil height, volume, organic matter, C:N and moisture content. A readme file was included to further explain file content. </p>
Relaxed predation selection on rare morphs of Ensatina salamanders (Caudata: Plethodontidae) promotes a polymorphic population in a novel dune sand habitat
<p>The Ensatina ring species represents a classic example of locally adapted lineages. The Monterey Ensatina (Ensatina eschscholtzii eschscholtzii) is a cryptic subspecies with brown coloration, however, a recently discovered polymorphic population within a wind-blown sand region also contains leucistic (pink) and xanthistic (orange) morphs. Leucism/xanthism frequency was mapped across the subspecies' range revealing that these morphs are generally rare or absent except within regions containing light-colored substrate. Attack rates were estimated using clay models of the three morphs, deployed only at the crepuscular period and during the night, on both light and dark substrates at a site within the dune sand region. Model selection found that the interaction between morph and substrate color best predicted attack rates. Typical morphs had equal attack rates on both substrates while xanthistic and leucistic morphs incurred significantly fewer attacks on light versus dark substrate, and there was no significant difference in attack rates among morphs on light substrates. These results support the idea that xanthistic and leucistic morphs are poorly adapted for dark substrates compared to typical morphs, but they are more or less equally adapted for light substrates. We suggest that this microgeographic island of relaxed selection on light-colored morphs helps explain the existence of this polymorphic population.</p>

Data from: N/P imbalance as a key driver for the invasion of oligothrophic dune systems by a woody legume
Oligotrophic ecosystems, previously considered to be more resilient to invasive plants, are now recognised to be highly vulnerable to invasions. In these systems, woody legumes show belowground ecosystem engineering characteristics that enable invasion, however, the underlying processes are not well understood. Using a Portuguese primary dune ecosystem as an oligotrophic model system, belowground biomass pools, turnover rates and stoichiometry of a native (Stauracanthus spectabilis) and an invasive legume (Acacia longifolia) were compared and related to changes in the foliage of the surrounding native (Corema album) vegetation. We hypothesized that the invasive legume requires less phosphorus per unit of biomass produced and exhibits an enhanced nutrient turnover compared to the native vegetation, which could drive invasion by inducing a systemic N/P imbalance. Compared with the native legumes, A. longifolia plants had larger canopies, higher SOM levels and lower tissue P concentrations. These attributes were strongly related to legume influence as measured by increased foliar N content and less depleted δ15N signatures in the surrounding C. album vegetation. Furthermore, higher root N concentration and increased nutrient turnover in the rhizosphere of the invader were associated with depleted foliar P in C. album. Our results emphasize that while A. longifolia itself maintains an efficient phosphorus use in biomass production, at the same time it exerts a strong impact on the N/P balance of the native system. Moreover, this study highlights the engineering of a belowground structure of roots and rhizosphere as a crucial driver for invasion, due to its central role in nutrient turnover. These findings provide new evidence that, under nutrient-limited conditions, considering co-limitation and nutrient cycling in oligotrophic systems is essential to understand the engineering character of invasive woody legumes.
