Conservation status assessment of banana crop wild relatives using species distribution modelling
<p><strong>Aim: </strong>Crop wild relatives (CWR) are an essential source of genetic material for the improvement of certain traits in related crop species. Despite their importance, increasing public, scientific and political support, large gaps exist in the amount of genetic material collected and conserved of many CWR. Here, we construct a dataset on the distribution of wild banana species (Musa spp.) and assess their risk and conservation status. We deal with the questions (1) what areas are potentially suitable for wild banana species (2) how much of the wild banana diversity is currently at risk or insufficiently conserved ex- and in-situ.</p> <p><span><strong>Location: </strong>Native distribution area of wild banana species, ranging from the northeastern states of India to northeastern Australia.</span></p> <p><span><strong>Methods:</strong> We assessed the potential environmental range of wild species using a species distribution modelling approach with MaxEnt. Extinction risk was evaluated following IUCN criterion B and the <i>ex- </i>and <i>in-situ</i> conservation status was assessed using an indicator for biodiversity and sustainable development targets.</span></p> <p><span><strong>Results:</strong> We found that 11 out of 59 assessed species can be considered as vulnerable and nine as endangered. Highest species richness was found along the border of south China and northern Vietnam, in the northeastern states of India and on the Malayan peninsula. Our distribution modelling approach indicates that the northern Indo-Burmese region has the highest environmental suitability for most wild banana species and that lowland rainforests in general are highly suitable for bananas. Assessment of <i>in</i>- and <i>ex-situ</i> conservation status indicates that 56 out of 59 assessed species are currently insufficiently conserved <i>ex-situ</i> and that 49 are of high priority for further conservation. Additional <i>in-situ</i> conservation is of high priority for six species and of medium priority for 40 species.</span></p> <p><span><strong>Main Conclusions:</strong> To date, little of the banana CWR are sufficiently conserved both <i>in- </i>and <i>ex-situ</i>.</span></p>

Genetic diversity of Horsfieldia tetratepala (Myristicaceae), an endangered plant species with extremely small populations to China: implications for its conservation
<p>Genetic variation determines the evolutionary potential of a species and is vital for fully understanding the evolution of a species, as well as for developing optimal conservation strategies. <i>Horsfieldia tetratepala</i> is an economically important rainforest tree which has declined steadily, mainly though habitat destruction, and an endangered, narrow endemic in China where it is also classified as a Plant Species with Extremely Small Populations (PSESP). Effective conservation strategies for <i>H. tetratepala</i> are required urgently, but limited information about its<i> </i>genome is available. Accordingly, restriction site-associated DNA sequencing (RAD_seq) was used to sequence sixty-three <i>H. tetratepala</i> trees covering ten isolated populations to assess genome-level diversity and population structure, generating 8,103 high-quality SNPs. Low genetic diversity and moderate genetic differentiation was observed among populations, but Bayesian clustering divided the sampled <i>H. tetratepala</i> populations into two genetic clusters, though with some populations from Guangxi and Yunnan intermixed. Because of increasing of habitat fragmentation and human disturbance, conservation priority should be placed on populations with higher genetic variation (e.g., BB, TKH, DWS, and GLQ). Overall, our study provides valuable genomic resources for <i>H. tetratepala</i> that will significantly advance the formulation of effective conservation strategies.</p>
Data for: Local contributions to beta-diversity in urban pond networks: implications for biodiversity conservation and management
<p><b>Aim:</b> An understanding of how biotic communities are spatially organised is necessary to identify and prioritize habitats within landscape-scale biodiversity conservation. Local Contribution to Beta diversity (LCBD) identifies individual habitats that make a significant contribution to beta-diversity and may have important practical implications, particularly for conservation of habitat networks. In this study, we develop and apply a conservation prioritisation approach based on LCBD in aquatic invertebrate communities from 132 ponds.</p> <p><b>Location:</b> Five urban settlements in the UK: Halton, Loughborough, Stockport, Birmingham, Huddersfield.</p> <p><b>Methods:</b> We partition LCBD into richness difference (nestedness: <sub>RichDiff</sub>LCBD) and species replacement (turnover: <sub>Repl</sub>LCBD) and identify key environmental variables driving LCBD. We examine LCBD at two scales relevant to conservation planning: within urban settlements and nationally across the UK.</p> <p><b>Results:</b> Significant differences in LCBD values were recorded among the five settlements. In four of the five urban settlements studied, pond sites with the greatest LCBD values typically showed high replacement values. Significant LCBD sites and sites with high taxonomic diversity together supported more of the regional species pool (70%-97%) than sites with high taxonomic diversity alone (54% to 94%) or what could be protected by the random selection of sites. LCBD was significantly associated with vegetation shading, surface area, altitude and macrophyte cover.</p> <p><b>Main conclusions:</b> Conservation prioritisation that incorporates LCBD and sites with high taxonomic diversity improves the effectiveness of conservation actions within pond habitat networks, ensures site supporting high biodiversity are protected, and provides a method to define a spatial network of protected sites. Identifying new, effective conservation approaches, particularly in urban areas where resources may be scarce and conflicts regarding land use exist, is essential to ensure biodiversity is fully supported and detrimental anthropogenic effects are reduced.</p>
