Data from: Upgrades of coastal protection infrastructure affect benthic communities
<ol> <li>Sea level rise, storm surges, aging and wear are forcing upgrades to breakwaters and seawalls to protect coastal areas from erosion and inundation. Such upgrades involve the introduction of new material which may consequently act as an ecological disturbance that can alter established marine communities and ecosystem function. Mitigating ecological impacts requires an understanding of how species assemblages are affected by such works.</li> <li>Here, we use the major upgrade of a regularly wave-overtopped breakwater as a case study to evaluate the impacts of upgrades to hard coastal protection structure on benthic rocky reef communities. An asymmetrical Before-After Control-Impact (BACI) experimental design was used to test interactive effects of the infrastructure upgrades on benthic communities.</li> <li>While benthic assemblages were not significantly different from controls prior to the upgrade, improving the defensive capacity of the breakwater significantly changed community structure. Notably, most taxonomic groups showed higher cover at the control sites than at the impacted site post-upgrade, with articulated calcareous algae (e.g. <i>Corallina officinalis</i> and <i>Amphiroa anceps</i>) showing an opposite trend.</li> <li> <i>Synthesis and applications</i>: Ecological implications and structural limitations make regular upgrading of existing infrastructure unsuitable as a long-term management strategy. More sustainable alternatives need to be considered, such as decommissioning of structures and retreat from flood-prone areas. This transition, however, will take time and requires a change of mindset and policies. Where upgrades are urgent, eco-engineering techniques can mitigate impacts to habitats and associated taxa.</li> </ol>
Data from: Post-fire recovery in coastal sage scrub: seed rain and community trajectory
Disturbance is a primary mechanism structuring ecological communities. However, human activity has the potential to alter the frequency and intensity of natural disturbance regimes, with subsequent effects on ecosystem processes. In Southern California, human development has led to increased fire frequency close to urban areas that can form a positive feedback with invasive plant spread. Understanding how abiotic and biotic factors structure post-fire plant communities is a critical component of post-fire management and restoration. In this study we considered a variety of mechanisms affecting post-fire vegetation recovery in Riversidean sage scrub. Comparing recently burned plots to unburned plots, we found that burning significantly reduced species richness and percent cover of exotic vegetation the first two years following a 100-hectare wildfire. Seed rain was higher in burned plots, with more native forb seeds, while unburned plots had more exotic grass seeds. Moreover, there were significant correlations between seed rain composition and plant cover composition the year prior and the year after. Collectively, this case study suggests that fire can alter community composition, but there was not compelling evidence of a vegetation-type conversion. Instead, the changes in the community composition were temporary and convergence in community composition was apparent within two years post-fire.
Data from: Phytoplankton community interactions and environmental sensitivity in coastal and offshore habitats
Assessing the relative importance of environmental conditions and community interactions is necessary for evaluating the sensitivity of biological communities to anthropogenic change. Phytoplankton communities have a central role in aquatic food webs and biogeochemical cycles, therefore, consequences of differing community sensitivities may have broad ecosystem effects. Using two long-term time series (28 and 20 years) from the Baltic Sea, we evaluated coastal and offshore major phytoplankton taxonomic group biovolume patterns over annual and monthly time-scales and assessed their response to environmental drivers and biotic interactions. Overall, coastal phytoplankton responded more strongly to environmental anomalies than offshore phytoplankton, although the specific environmental driver changed with time scale. A trend indicating a state shift in annual biovolume anomalies occurred at both sites and the shift's timing at the coastal site closely tracked other long-term Baltic Sea ecosystem shifts. Cyanobacteria and the autotrophic ciliate Mesodinium rubrum were more strongly related than other groups to this trend with opposing relationships that were consistent across sites. On a monthly scale, biotic interactions within communities were rare and did not overlap between the coastal and offshore sites. Annual scales may be better able to assess general patterns across habitat types in the Baltic Sea, but monthly community dynamics may differ at relatively small spatial scales and consequently respond differently to future change.
Data from: Effects of vicariant barriers, habitat stability, population isolation and environmental features on species divergence in the south-western Australian coastal reptile community
Identifying explicit hypotheses regarding the factors determining genetic structuring within species can be difficult, especially in species distributed in historically dynamic regions. To contend with these challenges, we use a framework that combines species distribution models, environmental data and multi-locus genetic data to generate and explore phylogeographic hypotheses for reptile species occupying the coastal sand-dune and sand-plain habitats of the south-western Australian biodiversity hotspot; a community which has both a high diversity of endemics and has varied dramatically in spatial extent over time. We use hierarchical AMOVA, summary statistic and distance-based analyses to explicitly test specific phylogeographic hypotheses. Namely, we test if biogeographic vicariance across barriers, habitat stability, population isolation along a linear habitat or fragmentation across different environments can explain genetic divergence within five co-distributed squamate reptile species. Our results show that patterns of genetic variation reflect complex and species-specific interactions related to the spatial distribution of habitats present currently and during repeated glacial minima, as opposed to being associated with historical factors such as habitat stability between glacial and inter-glacial periods or vicariant barriers. We suggest that the large impact of habitat characteristics over time (i.e., relative levels of habitat connectivity, climatic gradients and spatial heterogeneity of soil types) reflects the ecological restrictions of the sand-dune and sandplain reptile communities and may explain the lack of concordance across taxa. The study demonstrates the general utility of the approach for assemblage-level, as well as single species, phylogeographic study, including its usefulness for exploring biologically-informed hypotheses about what factors have influenced patterns of genetic variation.
Data from: Persistent differences between coastal and offshore kelp forest communities in a warming Gulf of Maine
Kelp forests provide important ecosystem services, yet coastal kelp communities are increasingly altered by anthropogenic impacts. Kelp forests in remote, offshore locations may provide an informative contrast due to reduced impacts from local stressors. We tested the hypothesis that shallow kelp assemblages (12-15 m depth) and associated fish and benthic communities in the coastal southwest Gulf of Maine (GOM) differed significantly from sites on Cashes Ledge, 145 km offshore by sampling five coastal and three offshore sites at 43.0 +/- 0.07° N latitude. Offshore sites on Cashes Ledge supported the greatest density (47.8 plants m-2) and standing crop biomass (5.5 kg m-2 fresh weight) of the foundation species Saccharina latissima kelp at this depth in the Western North Atlantic. Offshore densities of S. latissima were over 150 times greater than at coastal sites, with similar but lower magnitude trends for congeneric S. digitata. Despite these differences, S. latissima underwent a significant 36.2% decrease between 1987 and 2015 on Cashes Ledge, concurrent with a rapid warming of the GOM and invasion by the kelp-encrusting bryozoan Membranipora membranacea. In contrast to kelp, the invasive red alga Dasysiphonia japonica was significantly more abundant at coastal sites, suggesting light or dispersal limitation offshore. Spatial differences in fish abundance mirrored those of kelp, as the average biomass of all fish on Cashes Ledge was 305 times greater than at the coastal sites. Remote video censuses of cod (Gadus morhua), cunner (Tautaogolabrus adspersus), and pollock (Pollachius virens) corroborated these findings. Understory benthic communities also differed between regions, with greater abundance of sessile invertebrates offshore. Populations of kelp-consuming sea urchins Stronglyocentrotus droebachiensis were virtually absent from Cashes Ledge while small urchins were abundant onshore, suggesting recruitment limitation offshore. Despite widespread warming of the GOM since 1987, extraordinary spatial differences in the abundance of primary producers (kelp), consumers (cod) and benthic communities between coastal and offshore sites have persisted. The shallow kelp forest communities offshore on Cashes Ledge represent an oasis of unusually high kelp and fish abundance in the region, and as such, comprise a persistent abundance hotspot that is functionally significant for sustained biological productivity of offshore regions of the Gulf of Maine.
Data from: Tropical ancient DNA from bulk archaeological fish bone reveals the subsistence practices of a historic coastal community in southwest Madagascar
Taxonomic identification of archaeological fish bones provides important insights into the subsistence practices of ancient coastal peoples. However, it can be difficult to execute robust morphological identification of fish bones from species-rich fossil assemblages, especially from post-cranial material with few distinguishing features. Fragmentation, weathering and burning further impede taxonomic identification, resulting in large numbers of unidentifiable bones from archaeological sites. This limitation can be somewhat mitigated by taking an ancient DNA (aDNA) bulk-bone metabarcoding (BBM) approach to faunal identification, where DNA from non-diagnostic bone fragments is extracted and sequenced in parallel. However, a large proportion of fishing communities (both past and present) live in tropical regions that have sub-optimal conditions for long-term aDNA preservation. To date, the BBM method has never been applied to fish bones before, or to fossils excavated from an exposed context within a tropical climate. Here, we demonstrate that morphologically indistinct bulk fish bone from the tropics can be identified by sequencing aDNA extracted from 100 to 300 ya archaeological midden material in southwest Madagascar. Despite the biases of the approach, we rapidly obtained family, genus, and species-level assemblage information, and used this to describe a subset of the ichthyofauna exploited by an 18th century fishing community. We identified 23 families of fish, including benthic, pelagic, and coral-dwelling fishes, suggesting a reliance on a variety of marine and brackish habitats. When possible, BBM should be used alongside osteological approaches to address the limitations of both; however, this study highlights how genetic methods can nevertheless be a valuable tool for helping resolve faunal assemblages when morphological identification is hindered by taphonomic processes, lack of adequate comparative collections, and time constraints, and can provide a temporal perspective on fish biodiversity in the context of accelerated exploitation of the marine environment.
Long-term Spartina alterniflora invasion simplified soil seed bank and regenerated community in a coastal marsh wetland
<p><span>The coastal wetland is easily invaded by alien species due to its location in the land and sea transitional area. As a potential driving regeneration force, the soil seed bank is vital to community restoration and species diversity protection. To reveal the long-term <em>S</em>. <em>alterniflora</em> invasion impact on the soil seed banks and regenerated communities, we investigated the seed banks under the different vegetation types (<em>S</em>. <em>alterniflora</em>, <em>Phragmites</em> <em>australis</em>, <em>Scirpus</em> <em>mariquete</em>, ruderal and unvegetated site) and soil depths (0–5 cm and 5–10 cm) in the Chongming island coastal salt marsh wetland. The results showed that the soil seed bank richness and species density under different vegetation types were higher than aboveground vegetation, and those of 0–5 cm seed banks were higher than 5–10 cm, except for the unvegetated site. The species richness and the <em>S</em>. <em>alterniflora</em> seed proportion in the seed banks under the <em>S</em>. <em>alterniflora</em> communities (</span><span>S.AS</span><span>) were lower and larger, respectively, than other sites. The species composition between </span><span>S.AS</span><span> and the aboveground communities showed high similarity with aggregation phylogenetic structures in two soil depths. The seed bank variations at 0–5 cm and 5–10 cm depths were interpreted 3.03% and 2.25% by aboveground communities, <span>while</span> 4.92% and 5.55% were interpreted by soil microbial biomass. </span><span>The SEM model explained 98.1% and 91.8% of the seed banks' richness at the 0–5 cm depth and 5–10 cm depth, respectively, and explained 98.8% and 46.1% of the seed banks' species density at the 0–5 cm depth and 5–10 cm depth, respectively. </span><span>The aboveground vegetation biomass and abundance directly affected the 0–5 cm seed banks' richness and species density, while its height and biomass only affected the 5–10 cm seed banks' species density. The microbial biomass of the 0–10 cm soil depth indirectly affected the richness and species density of the 0-5 cm seed bank, and only affected the richness of the 5–10 cm seed bank. Soil physical and chemical properties only indirectly affected the 0–5 cm seed banks' species density.</span><span> The results provided a reference for the ecological evaluation of the impacts of <em>S</em>. <em>alterniflora</em> invasion into the coastal salt marsh wetland of eastern China and guidance for the protection and restoration of the native plant communities.</span></p>
"Building Resilient Coastal Communities through Nature-based Solutions and Empowerment Tools".
<p>This report provides an evidence base on how Nature-based Solutions (NbS) and Empowerment Tools (ET) can support resilience in coastal communities. Using a Rapid Evidence Assessment (REA), it synthesises the current state of the evidence concerning the role of NbS and community ET in addressing coastal challenges such as climate change across Europe. The outcomes and impacts of such approaches in fostering empowerment and resilience within these communities are presented, including methods and indicators to report and measure empowerment. This report was developed by an Eklipse Expert Working Group to respond to a request put forward by the Horizon Europe EmpowerUS project and is targeted for policy- and decisionmakers, researchers and practitioners, exploring the nexus between coastal resilience, NbS and empowerment. Through a great range of recommendations for research and policy, we hope to encourage to enhance resilience of coastal communities by ensure a wide dissemination of the knowledge to a broad set of stakeholders.</p>
