Coastal dry tropical forests in Florida and the Caribbean in peril: A review
<p>Coastal dry tropical forests (CDTFs) are important yet vulnerable ecosystems. In this paper, we highlight the special conservation issues facing CDTFs by focusing on one variant of the type, those that occupy limestone substrate in the northeastern Caribbean. Our analysis draws largely from the coastal terrestrial broadleaf forests of the northern Bahamas, the Florida Keys, and southwestern Puerto Rico. Based on surveys of storm surges recorded during major hurricanes during the last 50 years, we define CDTFs as coastal terrestrial broadleaf forests on ground surfaces elevated up to 5 m above sea level and occurring within 5 km of the coast. These forests are not only threatened by land-use change from urbanization but also climate-driven sea level rise (SLR) and hurricanes, which have degraded them and reduced their extent. CDTFs are distinguished from other dry tropical forests by the occasional influence of marine water incursion during periodic storms, requiring species common to these forests to have some level of salt tolerance despite experiencing well-drained, freshwater conditions during most of their life span. With precipitation being the sole freshwater source for most coastal dry tropical forests, SLR and the resulting salinization in the rooting zone subject these forests to increasingly stressful conditions. Hence, even a modest rise in sea level can push numerous imperiled and endangered species and coastal terrestrial broadleaf communities to the edge of their tolerance, causing a decline in extent or their complete disappearance. Outside of protected areas, rapid urbanization has fragmented these forests and reduced their extent, which in turn has modified the interaction between rising seas and forest function. This work emphasizes the need for refined risk assessments to be completed and for conservation measures to be enforced so that resources can be directed appropriately to prevent further loss of coastal dry tropical forests.</p>

Location and condition of gorgonian forests in Italian coastal waters
<p>Gorgonian forests are among the most complex of subtidal habitats in the Mediterranean Sea, supporting high biodiversity and providing diverse ecosystem services. Despite their iconic status, the geographical distribution and condition of gorgonian species is poorly known. Using multiple online data types our primary aims were to compile, map and analyse observations of gorgonian forests in Italian coastal waters to assess the biological complexity of gorgonian forests; evaluate impacts and vulnerable species, and identify areas of special interest inside and outside of existing MPAs to help prioritise conservation strategies and actions.</p> <p>Location: Italy. Mediterranean Sea.</p> <p>Methods: Using a multi-source data integration approach we collected and integrated data from<br> scientific publications, online databases, citizen science projects, SCUBA diver questionnaires and social media into a unified spatial framework providing up-to-date information on the geographical distribution, abundance, and health of major habitat-forming gorgonian species in Italian coastal waters.</p> <p>Results: Higher abundance and complexity of gorgonian species occurred outside MPAs. Areas of Special Interest (n=167) were identified (80 inside and 87 outside MPAs). Three locations supported all seven focal species: Capo Caccia MPA, Portofino MPA and Catania (unprotected). The purple gorgonian (Paramuricea clavata), the most abundant and geographically widespread species with highest forest complexity, also experienced the highest impact, possibly linked to thermal stress events, disease and fishing.</p> <p>Main conclusions: The multi-source approach was a rapid and cost-effective tool to gather, analyse and map disparate data on gorgonian forests spanning 27 years of underwater observations both inside and outside of marine protected areas (MPAs). The unique perspective given by this approach demonstrates the suboptimal protection of several habitat-forming gorgonian species. The approach has great potential for wider application and offers a more inclusive participatory model for crowdsourcing and repurposing underutilised observations while also increasing ocean literacy.</p>

Hotspots within a hotspot: Evolutionary measures unveil interesting biogeogeographic patterns for the conservation of the coastal forest in Chile
<p><span><strong>Aim</strong>:</span><span> Given the continuous loss of biodiversity, there is an urgent need to study its patterns to generate conservation measures. Complementing the traditional patterns with indices that incorporate evolutionary aspects such as phylogenetic diversity or phylogenetic endemism (PD and PE) allows us to infer possible historical processes that could explain the conformation of current biodiversity. Coastal forests in Chile are part of a biodiversity hotspot of high endemism that is under threat. In this study, patterns of richness and endemism were determined and contrasted with the evolutionary indices PD, PE, PDres (residual PD), RPD (relative PD), and RPE (relative PE) to infer historical processes that could have shaped the current diversity patterns. We also compared these indices at different taxonomic levels.</span></p> <p><strong><span>Location</span></strong><span>: Thirteen sites on a latitudinal gradient between 30°S and 40°S that are part of the Chilean Coastal mountain range.</span></p> <p><span><strong>Taxon</strong>:</span><span> Woody flora at the species level.</span></p> <p><span><strong>Methods</strong>:</span><span> DNA was extracted and three genes were sequenced for 95% of the species. A phylogeny was constructed to calculate evolutionary indices based on PD and PE and compared at different taxonomic levels. </span></p> <p><span><strong>Results</strong>: </span><span>The results of PD and PE were spatially consistent with those of richness and endemism, but evolutionarily important sites were discovered. PD-derived indices indicate three evolutionary hotspots, a cradle-type site with a predominance of neoendemisms (generating recent diversity) at 33°S, two museum-type sites with a predominance of paleoendemisms (maintaining relict diversity) at 30°S and 40°S and the last one with high PD and PE at 37°.</span></p> <p><span><strong>Main conclusion</strong>:</span><span> We found interesting evolutionary hotspots within the hotspot of Central Chile with different characteristics. Incorporating measures that consider the evolutionary aspect has important implications for the conservation of highly diverse and endemic areas.</span></p>
