Morphometry of Atlantic Ocean Barrier Islands, Lagoons and Marshes 1978
This data set contains morphometric measures of the lagoons of the Atlantic Coast. The goal was to obtain a measure of the complexity of the marshes that filled the lagoons behind the barrier islands. ABSTRACT The width, depth, marsh cover, and marsh-water interfaces were recorded for the lagoons along the 2000 km of coast between Long Island, New York and Miami, Florida. Eigenvectors of these variables for 134 sites (cases) were calculated and analyzed to identify the characteristic variations of these morphometric attributes. Three modes of variation account for 88% of Ihe variance of the original data: the dominant mode contrasts wide, complex lagoons and narrow, simple lagoons. The second contrasts wide, simple with narrow, complex lagoons. A third mode contrasts wide, shallow, complex with narrow, deep lagoons with few marsh-water intersects. The first mode is correlated geographically with variations in the steepness and curvature of the inner portion of the continental shelf. Using variations in the morphometric attributes of the lagoon-marsh system and the fronting islands on the ocean side, the Atlantic coast barrier islands, lagoons, and marshes are classified into three regions and eight sub-regions. The concept of barrier island ''ensembles'' along the Atlantic coast is reviewed in terms of the island-lagoon marsh system and their covariation with offshore bathymetry. The concept of these ensembles is strongly supported.
Data from: Does biological intimacy shape ecological network structure? A test using a brood pollination mutualism on continental and oceanic islands
Biological intimacy—the degree of physical proximity or integration of partner taxa during their life cycles—is thought to promote the evolution of reciprocal specialization and modularity in the networks formed by co‐occurring mutualistic species, but this hypothesis has rarely been tested. Here, we test this "biological intimacy hypothesis" by comparing the network architecture of brood pollination mutualisms, in which specialized insects are simultaneously parasites (as larvae) and pollinators (as adults) of their host plants to that of other mutualisms which vary in their biological intimacy (including ant‐myrmecophyte, ant‐extrafloral nectary, plant‐pollinator and plant‐seed disperser assemblages). We use a novel dataset sampled from leafflower trees (Phyllanthaceae: Phyllanthus s. l. [Glochidion]) and their pollinating leafflower moths (Lepidoptera: Epicephala) on three oceanic islands (French Polynesia) and compare it to equivalent published data from congeners on continental islands (Japan). We infer taxonomic diversity of leafflower moths using multilocus molecular phylogenetic analysis and examine several network structural properties: modularity (compartmentalization), reciprocality (symmetry) of specialization and algebraic connectivity. We find that most leafflower‐moth networks are reciprocally specialized and modular, as hypothesized. However, we also find that two oceanic island networks differ in their modularity and reciprocal specialization from the others, as a result of a supergeneralist moth taxon which interacts with nine of 10 available hosts. Our results generally support the biological intimacy hypothesis, finding that leafflower‐moth networks (usually) share a reciprocally specialized and modular structure with other intimate mutualisms such as ant‐myrmecophyte symbioses, but unlike nonintimate mutualisms such as seed dispersal and nonintimate pollination. Additionally, we show that generalists—common in nonintimate mutualisms—can also evolve in intimate mutualisms, and that their effect is similar in both types of assemblages: once generalists emerge they reshape the network organization by connecting otherwise isolated modules.
Climate controls plant life form patterns on a high-elevation oceanic island
<p>Aim: Plant life forms characterize key morphological strategies that enable large-scale comparisons of plant communities. This study applies Raunkiær's plant life form concept that was developed for temperate climate to a subtropical island flora, in parts, dominated by summer aridity. We quantify how plant life form patterns as well as patterns of important plant functional traits (PFTs) relate to important climate and topographic characteristics. Location: La Palma, Canary Islands Taxon: Flora of La Palma.</p> <p>Methods: We assigned each native plant species a plant life form, i.e., phanerophyte, chamaephyte, hemicryptophyte, geophyte and therophyte, as well as PFTs (succulence and N-fixer). We used stacked species distribution models to assess occurrence probability for each species using the Atlantis database (500x500 m grid). We related richness and percentage values for each plant life form and PFT to climate and topography.</p> <p>Results: Plant life forms and PFTs showed a clear pattern within geographic but also climate space, while topography had a minor effect. Phanerophytes mainly contributed to the flora in humid areas. Chamaephytes and hemicryptophytes most strongly contributed to the summit scrub flora and, to some degree, also to the arid coastal regions. Geophytes and therophytes were mainly found in dry coastal regions. N-fixers contributed mainly to warm-arid and cool-arid regions, while succulent species were mainly found in arid coastal regions.</p> <p>Main conclusions: Raunkiær's plant life form concept can be comprehensively transferred to a subtropical island flora by adapting to local unfavorable growing conditions, i.e., aridity. Using the strong environmental gradients offered by our study island, we identify substantial climate-driven variation in patterns of plant life forms and PFTs that might be used for large scale comparisons in macroecological studies. The growth strategies reflected in Raunkiær's plant life forms suggest differences in species establishment and coexistence dynamics within different parts of the island's climate space.</p>

Data from: Early diversification dynamics in a highly successful insular plant taxon are consistent with the general dynamic model of oceanic island biogeography
<p>The general dynamic model (GDM) of oceanic island biogeography views oceanic islands predominantly as sinks rather than sources of dispersing lineages. To test this, we conducted a biogeographic analysis of a highly successful insular plant taxon, <em>Cyrtandra </em>and inferred directionality of dispersal and founder events throughout the four biogeographical units of the Indo-Australian Archipelago (IAA), namely Sunda, Wallacea, Philippines, and Sahul. Sunda was recovered as the major source area, followed by Wallacea, a system of oceanic islands. The relatively high number of events originating from Wallacea is attributed to its central location in the IAA and its complex geological history selecting for increased dispersibility. We also tested if diversification dynamics in <em>Cyrtandra </em>follow predictions of adaptive radiation, which is the dominant process as per the GDM. Diversification dynamics of dispersing lineages of <em>Cyrtandra</em> in the Southeast Asian grade showed early bursts followed by a plateau, which is consistent with adaptive radiation. We did not detect signals of diversity-dependent diversification, and this is attributed to Southeast Asian cyrtandras<em> </em>occupying various niche spaces, evident by their wide morphological range in habit and floral characters. The Pacific clade, which arrived at the immaturity phase of the Pacific Islands, showed diversification dynamics predicted by the Island Immaturity Speciation Pulse (IISP) model, wherein rates increase exponentially, and their morphological range is controlled by the least action effect favoring woodiness and fleshy fruits. Our study provides a first step toward a framework for investigating diversification dynamics as predicted by the GDM in highly successful insular taxa.</p>
