Shedding light on dark taxa in sky‐island Appalachian leaf litter: Assessing patterns of endemicity using large‐scale, voucher‐based barcoding

Insect Conservation and Diversity, Journal Year: 2023, Volume and Issue: 17(1), P. 16 - 30

Published: Nov. 2, 2023

Abstract Developing systematic conservation plans depends on a wealth of information region's biodiversity. For ‘dark taxa' such as arthropods, data are usually very incomplete and in most cases left out from assessments. Sky islands important often fragile biodiversity hotspots. Southern Appalachian high‐elevation spruce–fir forests represent particularly threatened sky‐island ecosystem, hosting numerous endemic species, but their arthropods remain understudied. Here we use voucher‐based megabarcoding to explore genetic differentiation among leaf‐litter arthropod communities these highlands, examine the extent which they dispersed more or less coherent manageable distributed unit. We assembled dataset comprising than 6000 COI sequences representing diverse groups assess species richness sharing across peaks ranges. Comparisons were standardised taxa using automated delimitation, measuring endemism levels by putative species. Species was high, with sites 86 199 litter (not including mites myriapods). Community profiles suggest that around one fourth unique single sky third all limited particular range. Across major taxa, endemicity lowest Araneae, highest neglected like Isopoda, Pseudoscorpionida, Protura Diplura. habitat host significantly distinct communities, high local endemicity. This is first work provide clear picture peak range uniqueness for taxonomically broad sample. Ensuring protection sizeable fraction will therefore require attention at relatively fine spatial scale.

Published: April 1, 2024

Abstract A global decline in seagrass populations has led to renewed calls for their conservation as important providers of biogenic and foraging habitat, shoreline stabilization carbon storage. Eelgrass ( Zostera marina ) occupies the largest geographic range among species spanning a commensurately broad spectrum environmental conditions. In Canada, eelgrass is managed single phylogroup despite occurring across three oceans ocean temperatures salinity gradients. Previous research focused on applying relatively few markers reveal population structure eelgrass, whereas whole‐genome approach warranted investigate cryptic inhabiting different basins localized We used pooled re‐sequencing characterize structure, gene flow associations 23 ranging from Northeast United States Atlantic, subarctic Pacific Canada. identified over 500,000 SNPs, which when mapped chromosome‐level genome assembly revealed six clades study area, with pairwise F ST 0 neighbouring 0.54 between Atlantic coasts. Genetic diversity was highest lowest subarctic, consistent colonization Arctic less than 300 kya. Using redundancy analyses two climate change projection scenarios, we found that are predicted be potentially more vulnerable through genomic offset predictions. Conservation planning Canada should thus ensure representative each clade included within national network so latent genetic protected, maintained. Northern populations, particular, may require additional mitigation measures given potential susceptibility rapidly changing climate.

In our present age of extinction, conservation managers must use limited resources efficiently to conserve species and the genetic diversity within them. To intraspecific variation, we understand geographic distribution variation plan management actions that will cost-effectively maximise its retention. Here, a genome-wide single-nucleotide polymorphism (SNP) dataset consisting 12,962 loci 384 individuals inform Endangered northern quoll (Dasyurus hallucatus), carnivorous marsupial distributed patchily across Australia. Many populations have declined or are currently declining, driven by range-expanding cane toad (Rhinella marina). We (1) confirm population genomic structure, (2) investigate contribution each overall diversity, (3) conduct prioritisation analyses at several spatial hierarchical scales using popular planning algorithms, (4) patterns inbreeding. find single population, even populations, not prevent loss substantial amounts adaptive capacity. Rather, least eight from is necessary retain 90 % SNP alleles. also show more geographically isolated such as those on islands, very small contributions relatively high levels inbreeding compared mainland populations. Our study highlights importance conserving multiple genetically distinct effectively in undergoing widespread declines, demonstrates criteria prioritise management.

Abstract Molecular tools are increasingly applied for assessing and monitoring biodiversity informing conservation action. While recent developments in genetic genomic methods provide greater sensitivity analysis the capacity to address new questions, they not equally available all practitioners: There is considerable bias across institutions countries access technologies, funding, training. Consequently, many cases, more accessible traditional data (e.g., microsatellites) still utilized making decisions. Conservation approaches need be pragmatic by tackling clearly defined management questions using most appropriate available, while maximizing use of limited resources. Here we present some key consider when applying molecular toolbox actionable management. Finally, highlight a number important steps addressed collaborative way, which can facilitate broad integration into conservation.

A framework for identifying multiscenario priorities based on SCP theory to promote the implementation of municipal territorial ecological conservation planning policy in China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 155, P. 111057 - 111057

Published: Oct. 12, 2023

Currently, research on the methodological framework for identifying conservation priority areas in China's territorial ecological planning pays limited attention to plan's implementability. Therefore, this study, we developed a new prioritization implementation based systematic (SCP) theory, which not only incorporated multiple types of key indicators assessment but also provided managers with differentiated decision-making scenarios, including use Integrated Valuation Ecosystem Services and Trade-offs (InVEST) model, Marxan Zonation model. We applied Xi'an, megacity northwest China. To evaluate effectiveness framework, comparison was made between two scenarios: scenarios (SCPs) ecologically important (EIs) previous main methodology (which integrates level ecosystem service provision vulnerability). Under SCPs EIs, are 2,118.35 km2 4,447.15 km2, respectively, gained slightly fewer benefits than EIs caused less loss economic terms GDP (27.8884 million yuan 494.3732 respectively). This shows that can help minimize costs while satisfying each benefit as much possible compared approaches, thus contributing implementability plan. In future works, application multiscenario SCP theory be further expanded, flexible solutions landscape similar facing urgent needs.
