Modelling the response of mangroves and saltmarshes to sea-level rise: model development and validation
<p>Data used to parameterise and calibrate a model (IWEM0D) of the response of coastal wetlands to sea-level rise. Model parameterisation with core data from Westernport Bay, Victoria, Australia.</p> <p>IWEM0D (Intertidal Wetland Evolution Model - 0D) simulates how mangrove forests and saltmarsh wetlands respond to sea-level rise. The model framework, as detailed in Rogers et al. (in review), treats surface elevation change over time as a function of:</p> <ul> <li>Present elevation <code>E</code></li> <li>Inorganic/mineral matter accumulation rate <code>MAR</code></li> <li>Organic matter addition rate <code>OAR</code> for mangroves and saltmarsh</li> <li>Autocompaction <code>AC</code></li> </ul> <p>Specifically, incremental change in surface elevation <code>E</code> over time <code>t</code> is modelled as:</p> <p><code>E[t+1] = E[t] + MAR[t] + OAR[t] - AC[t]</code></p>

FIG. 1. — Phylogenetic tree generated from Bayesian analysis of concatenated LSU, SSU, TEF1α and ITS sequence data of Phaeosphaeriaceae. Values above the branches indicate maximum parsimony and maximum likelihood bootstrap ≥ 70%, (MP/ML). Values at the third positions, respectively, above or below the branches represent posterior probabilities (PP ≥ 0.95) from Bayesian inference analysis. The new isolate is in blue. The tree is rooted with Leptosphaeria doliolum (Pers.) Cesati & De Notaris and Paraleptosphaeria dryadis (Johanson) Gruyter, Aveskamp & Verkley.

Sustained mangrove reproduction despite major turnover in pollinator community composition at expanding range edge
<p><strong>Background and Aims</strong></p> <p>How well plants reproduce near their geographic range edge can determine whether distributions will shift in response to changing climate. Reproduction at the range edge can be limiting if pollinator scarcity leads to pollen limitation, or if abiotic stressors affect allocation to reproduction. For many animal-pollinated plants with expanding ranges, the mechanisms by which they have overcome these barriers are poorly understood.</p> <p><strong>Methods </strong></p> <p>In this study, we examined plant-pollinator interactions hypothesized to impact reproduction of the black mangrove, <em>Avicennia germinans</em>, which is expanding northward in coastal Florida, USA. We monitored insects visiting <em>A. germinans</em> populations varying in proximity to the geographic range edge, measured the pollen loads of the most common insect taxa and pollen receipt by <em>A. germinans</em> stigmas, and quantified flower and propagule production. <strong> </strong></p> <p><strong>Key Results</strong></p> <p>We found that despite an 84% decline in median floral visits by insects at northernmost vs. southernmost sites, range-edge pollen receipt remained high. Notably, local floral visitor assemblages exhibited substantial turnover along the study's latitudinal gradient, with large-bodied bees and hover flies increasingly common at northern sites. We also observed elevated flower production in northern populations and higher per capita reproductive output at the range edge. Furthermore, mean propagule mass in northern populations was 18% larger than propagules from the southernmost populations. <strong> </strong></p> <p><strong>Conclusions</strong></p> <p>These findings reveal no erosion of fecundity in <em>A. germinans</em> populations at range limits, allowing rapid expansion of mangrove cover in the region. These results also illustrate that substantial turnover in the assemblage of flower-visiting insects can occur at an expanding range edge without altering pollen receipt.</p>
