Genomic tools for comparative conservation genetics among three recently diverged stag beetles (Lucanus, Lucanidae)
<p>We are witnessing a rapid decline in global biodiversity. International protocols and local conservation laws have been installed to counter such an unprecedented rate of decline. However, quantitatively evaluating how much biodiversity has been lost due to climatic and anthropogenic effects and how much biodiversity has been restored due to conservation efforts remain challenging. We applied a comparative conservation genomic approach to statistically and quantitatively address these questions using three geographical taxa from a stag beetle species complex. We found that the three sky-island taxa formed three independently evolving units without detectable post-divergence gene flow; furthermore, the three taxa, which have been divergent from each other since the mid-Pleistocene, have experienced episodes of demographic decline in the past. More importantly, even though idiosyncratic anthropogenic exploitations have been hypothesized to impact the recent demographic history (< 100 years) differently, we found a shared pattern of continuous decline in effective population size among the three geographical taxa. We argue that future empirical studies should include more taxa, in addition to the focal species, that may or may not be affected by the focal historical events to avoid making biased conservation plans.</p>

Data from: Direct evidence of permeability evolution of Nanan granite after two cooling paths under different confining pressures: A comparative study
<p>Permeability decides the mass transfer behavior and plays a key role in the heat extraction of enhanced geothermal systems (EGSs), and the aim of the injection of cooling water is to enhance permeability within the geothermal reservoirs. Direct evidence of how cool water affecting permeability evolution is still limited. Therefore, we explored the permeability evolution of Nanan granite after air and water cooling under different confining pressures combined with optical microscopy and X-ray CT observation. We found that there are lots of microdefects observed in Nanan granite after two cooling paths, which dominantly drives the evolution of permeability from a microscopic scale. The permeabilities of granite under water-cooling condition are always larger than those under air-cooling condition, and water-cooling treatment further enhances the permeability of specimens. The permeabilities of granite specimens after two cooling paths decrease with confining stress. More microcracks and better connectivity among microcracks produce a larger permeability within the specimen after water cooling. The observed microcracks are regarded as the seepage channels and direct microscale evidence of permeability evolution of granite after two cooling paths. Our results may suggest that water injection is an efficient way for permeability enhancement due to thermal microcracks propagation in thermal simulation.</p>
Comparative genomic analysis of chemosensory-related gene families in gastropods
<p>Chemoreception is critical for the survival and reproduction of animals. Except for a reduced group of insects and spiders, the molecular identity of chemosensory proteins is poorly understood in invertebrates. Gastropoda is the extant mollusk class with the greatest species richness, including marine, freshwater, and terrestrial lineages, and likely, highly diverse chemoreception systems. Here, we performed a comprehensive comparative genome analysis taking advantage of the chromosome-level information of two Gastropoda species, one of which belongs to a lineage that underwent a whole genome duplication event. We identified thousands of previously uncharacterized chemosensory-related genes, the majority of them encoding G protein-coupled receptors (GPCR), mostly organized into clusters distributed across all chromosomes. We also detected gene families encoding degenerin epithelial sodium channels (DEG-ENaC), ionotropic receptors (IR), sensory neuron membrane proteins (SNMP), Niemann–Pick type C2 (NPC2) proteins, and lipocalins, although much smaller in size. Our phylogenetic analysis of the GPCR gene family across protostomes revealed: (i) large gene family expansions in Gastropoda; (ii) clades including members from all protostomes; and (iii) species-specific clades with a huge number of receptors. For the first time, we provide new and valuable knowledge into the evolution of the chemosensory gene families in invertebrates other than arthropods.</p>

Data from Comparing organic carbon bound to different minerals in wetland and upland soils
<p>Here is the data and drawing code for "comparing organic carbon bound to different minerals in wetland and upland soils". Mineral binding of organic carbon (OC) is vital for soil organic carbon (SOC) persistence. However, the relative importance of two main types of soil minerals - metal oxides and silicate clay - in SOC protection remains unclear, hampering our ability to predict and protect this important pool of persistent SOC. Here, using sequential dissolution by dithionite and hydrofluoric acid, we quantified OC bound to metal oxides versus silicate clay in soils from contrasting environments (i.e., wetlands and uplands). We find that metal oxides override silicate clay in SOC protection in both wetlands and uplands, and OC bound to soil minerals (especially metal oxides) constitutes a higher fraction of SOC in wetlands than uplands, suggesting an underappreciated role of mineral protection in wetland SOC preservation. Furthermore, using lignin phenol analysis in tandem, we find that silicate clay dissolution may release an addition of ~23% lignin phenols from soils, potentially providing a means to assess ‘hidden’ lignin in mineral matrices. These findings highlight the important role of different soil minerals in the protection of SOC and its components in contrasting terrestrial environments, and advance our understanding of predicting and protecting this important pool of persistent SOC.</p>

Comparative Analysis of 3D Printed Bridge Construction in Louisiana
<p>A construction 3D printing system could result in automated infrastructure development at reduced cost and time, significantly boosting overall productivity. Although there has been a growing interest in using construction 3D printing for projects such as house construction, implementing this innovative technology for infrastructure development, particularly bridge construction, has not been investigated as extensively. This study aims to compare the environmental impact of precast and 3D concrete printing (3DCP) techniques with a pedestrian bridge case study, located in Louisiana, where the bridge elements were 3D printed off-site and then transported and assembled on the bridge site. A detailed cradle-to-site life cycle assessment has been performed from the standpoint of material, construction, and installation stages, using an open-source software called OpenLCA. The results of this study showed that the mixtures commonly used in 3DCP have a higher negative environmental impact compared to the precast method due to the higher percentage of cement used in these materials. However, since 3DCP used less material than the precast technique, there is no significant difference in the environmental impact of the total concrete used between the 3DCP and precast bridges. In addition, due to the use of reinforcement and formwork in the precast technique, the environmental impact of the total materials used in the precast bridge was more adverse than the 3DCP bridge. Notably, due to use of electricity for printing, the negative environmental impact of the construction process in 3DCP was significantly higher than in the precast technique. Finally, the total carbon dioxide equivalent emitted during the construction of the 3DCP bridge was 80% of the precast bridge.</p>
Data from: Comparative LCA studies of simulated HMF-biorefineries from maize and miscanthus as an example of first- and second-generation biomass as a tool for process development
<p class="MsoNormal"><span>5-Hydroxymethylfurfural (HMF) is a versatile platform chemical for a fossil free, bio-based chemical industry. HMF can be produced by using fructose as a feedstock. Using edible, first-generation biomass to produce chemicals has been questioned in terms of potential competition with food supply. Second-generation biomass like miscanthus could be an alternative. However, there is a lack of information if second-generation lignocellulosic biomass is a more sustainable feedstock to produce HMF. Therefore, a life cycle assessment was performed in this study to determine the environmental impacts of HMF production from miscanthus and to compare it with HMF from high fructose corn syrup (HFCS). HFCS from either Hungary or Baden-Württemberg (Germany) was considered. Compared to the HFCS biorefineries the miscanthus concept is producing less emissions in all impact categories studied, except land occupation. Overall, the production and usage of second-generation biomass could be especially beneficial in areas where the use of N-fertilizers is restricted. Besides, conclusions for the further development of the on-farm-biorefinery concept were elaborated. For this purpose, process simulations from a previous study were used. Results of the previous study in terms of TEA and the current LCA study in terms of environmental sustainability indicate that the lignin depolymerization unit in the miscanthus biorefinery has to be improved. The scenario without lignin depolymerization performs better in all impact categories. The authors recommend to not further convert the lignin to products like phenol and other aromatic compounds. The results of the contribution analyses show that the major impact in the HMF production is caused by the auxiliary materials in the separation units and the required heat. Further technical development should focus on efficient heat as well as solvent use and solvent recovery. At this point further optimizations will lead to reduced emissions and costs at the same time. The presented data set is the used inventory to model the environmental impacts. </span></p>
