Ectomycorrhizal fungal effects on soil carbon storage, root litter decomposition, and fungal necromass decomposition
This project investigates the impacts of ectomycorrhizal-saprotrophic fungal interactions on soil C storage and the decomposition of root litter and fungal necromass. Specifically, we conducted a field experiment wherein the ectomycorrhizal:saprotrophic fungal ratio was reduced via experimental trenching (with control plots left untrenched). From these plots we then measured bulk soil C stocks, particulate organic matter C stocks, mineral associated organic matter C stocks, and the decomposition of root litter and fungal necromass. The Cedar Creek Ecosystem Science Reserve (CCESR) experiment name is e309 "The effects of mycelial morphology and mycorrhizal type on fungal necromass decomposition."

16S Phyloseq R object accompanying the paper: Effects of storage methods on total bacterial count and microbial composition of bovine colostrum
<p>This ready to load <strong>phyloseq</strong> R S4 object contains the ASV table, taxonomy table and sample metadata (16S V3-V4). This data was build using the DaDa2 (version 1.12.1) and phyloseq (version 1.32) R packages using our raw Illumina MiSeq PE300 sequencing data deposited at NCBI-SRA under BioProject: PRJNA872909.</p> <p>The accompanying (peer-reviewed) scientific article can be found here: </p> <ul> <li>https://www.todo</li> <li>DOI: todo</li> </ul> <p> </p> <p><strong>Study/draft abstract:</strong></p> <p>Lisa Robbers, Hannes Bijkerk, Lars Ravesloot, Alex Bossers, Mirjam Nielen, Ruurd Jorritsma, Ad Koets, Lindert Benedictus</p> <p>Neonatal calves need to acquire passive immunity through maternal colostrum, as they are immunologically naïve and the structure of the bovine placenta does not allow passage of maternal antibodies during pregnancy. Milked colostrum is not initially sterile and may even contain high bacterial counts. Minimizing total bacterial counts in colostrum is generally advised, however bacterial quality of colostrum comprises more than just bacterial quantities, but also depends on the specific bacteria present. While duration and temperature of colostrum storage are known to affect total plate counts (TPC), less is known about the effects of storage on the actual bacterial composition of the TPC. We speculated that, depending on the storage conditions, colostrum is a substrate in which certain bacterial species can thrive affecting the quality of colostrum.</p> <p>We therefore aimed to characterize the effects of different colostrum storage methods on the composition of the viable, aerobic, microbial community. Colostrum samples were stored at different temperatures and for different durations. Next, bacterial growth was assessed using the aerobe plate count culture method, followed by 16S rRNA gene amplicon sequencing. Differences in the TPC bacterial compositions of the stored colostrum samples, as determined by 16S rRNA gene amplicon sequencing, were mostly explained by the variation in bacterial composition of the colostrum sample directly after milking. In line with earlier studies, the results from our study show that the TPC increased when colostrum was stored for 24 hours at room temperature, but not when stored in a refrigerator for the same duration. Community structure of the TPC of colostrum stored at room temperature for 24 hours and stored in a refrigerator for a week was significantly different from the baseline samples. The 16S rRNA sequencing results indicate this is because of increased numbers of <em>Enterobacteriaceae.</em> <em>Enterobacteriaceae</em> abundance in refrigerated samples seemed to remain stable for the first 24 hours, but increased drastically after one week. The results indicate that microbial composition of stored colostrum is mostly influenced by the composition of the colostrum sample directly after milking, which is most probably the result of contamination or other environmental influences during the milking process. This study provides a deeper insight in the changes in the microbial composition of colostrum TPC during practical storage conditions and provides a primer for more detailed research into the determinants of bacterial composition of colostrum and the linked health effects.</p>

Data for: Effects of long-term ethanol storage of blood samples on the estimation of telomere length
<p>Telomeres, DNA structures located at the end of eukaryotic chromosomes, shorten with each cellular cycle. The shortening rate is affected by factors associated with stress, and, thus telomere length has been used as a biomarker of ageing, disease, and different life history trade-offs. Telomere research has received much attention in the last decades; however, there is still a wide variety of factors that may affect telomere measurements and to date no study has thoroughly evaluated the possible long-term effect of a storage medium on telomere measurements. In this study we evaluated the long-term effects of ethanol on relative telomere length (RTL) measured by qPCR, using blood samples of magpies collected over twelve years and stored in absolute ethanol at room temperature. We firstly tested whether storage time had an effect on RTL and secondly we modelled the effect of time of storage (from 1 to 12 years) in differences in RTL from DNA extracted twice in consecutive years from the same blood sample. We also tested whether individual amplification efficiencies were influenced by storage time, and whether this could affect our results. Our study provides evidence of an effect of storage time on telomere length measurements. Importantly, this effect shows a pattern of decreasing loss of telomere sequence with storage time that stops after approximate 4 years of storage, which suggests that telomeres may degrade in blood samples stored in ethanol. Our method to quantify the effect of storage time could be used to evaluate other storage buffers and methods. Our results highlight the need to evaluate the long-term effects of storage on telomere measurements, particularly in long-term studies.</p>

Data from: Effects of restoration on tree communities and carbon storage in rainforest fragments of the Western Ghats, India
Ecological restoration is a leading strategy for reversing biodiversity losses and enhancing terrestrial carbon sequestration in degraded tropical forests. There have been few comprehensive assessments of recovery following restoration in fragmented forest landscapes, and the efficacy of active versus passive (i.e., natural regeneration) restoration remains unclear. We examined 11 indicators of forest structure, tree diversity and composition (adult and sapling), and aboveground carbon storage in 25 pairs of actively restored (AR; 7–15 yr after weed removal and mixed-native tree species planting) and naturally regenerating (NR) plots within degraded rainforest fragments, and in 17 less-disturbed benchmark (BM) rainforest plots in the Western Ghats, India. We assessed the effects of active restoration on the 11 indicators and tested the hypothesis that active restoration effects increase with isolation from contiguous and relatively intact rainforests. Active restoration significantly increased canopy cover, adult tree and sapling density, adult and sapling species density (overall and late successional), compositional similarity to benchmarks, and aboveground carbon storage, which recovered 14–82% toward BM targets relative to NR baselines. By contrast, tree height–diameter ratios and the proportion of native saplings did not recover consistently in actively restored forests. The effects of active restoration on canopy cover, species density (adult), late successional species density (adult and sapling), and species composition, but not carbon storage, increased with isolation across the fragmented landscape. Our findings show that active restoration can promote recovery of forest structure, composition, and carbon storage within 7–15 yr of restoration in degraded tropical rainforest fragments, although the benefits of active over passive restoration across fragmented landscapes would depend on indicator type and may increase with site isolation. These findings on early stages of recovery suggest that active restoration in ubiquitous fragmented landscapes of the tropics could complement passive restoration of degraded forests in less fragmented landscapes, and protection of intact forests, as a key strategy for conserving biodiversity and mitigating climate change.
Data from: A synthesis of the effects of cheatgrass invasion on U.S. Great Basin carbon storage
<p>Non-native, invasive Bromus tectorum (cheatgrass) is pervasive in sagebrush ecosystems in the Great Basin ecoregion of the western U.S., competing with native plants and promoting more frequent fires. As a result, cheatgrass invasion likely alters carbon (C) storage in the region. Many studies have measured C pools in one or more common vegetation types: native sagebrush, invaded sagebrush, and cheatgrass-dominated (often burned) sites, but these results have yet to be synthesized.</p> <p>We performed a literature review to identify studies assessing the consequences of invasion on C storage in aboveground biomass (AGB), belowground biomass (BGB), litter, organic soil, and total soil. We identified 41 articles containing 386 unique studies and estimated C storage across pools and vegetation types and used linear mixed models to identify the main predictors.</p> <p>We found consistent declines in biomass C with invasion: AGB C was 55% lower in cheatgrass (40 ± 4 g C m-2) than in native sagebrush (89 ± 27 g C m-2) and BGB C was 62% lower in cheatgrass (90 ± 17 g C m-2) than native sagebrush (238 ± 60 g C m-2). In contrast, litter C was > 4x higher in cheatgrass (154 ± 12 g C m-2) compared to native sagebrush (32 ± 12 g C m-2). Soil organic C (SOC) in the top 10 cm was significantly higher in cheatgrass than in native or invaded sagebrush. SOC below 20 cm was significantly related to the time since most recent fire and losses were observed in deep SOC in cheatgrass systems > 5 years after a fire. There were no significant changes in total soil C across vegetation types.</p> <p>Synthesis and Applications: Cheatgrass invasion decreases biodiversity and rangeland productivity and alters fire regimes. Our findings indicate cheatgrass invasion also results in persistent biomass C losses that occur with this state change. We estimate that conversion from native sagebrush to cheatgrass leads to a net reduction of C storage in biomass and litter of 76 g C m-2, or 16 Tg C across the Great Basin without management practices like native sagebrush restoration or cheatgrass removal.10-Sep-2020</p>
An investigation on the effect of high energy storage anchor on surrounding rock conditions
High pre-tension bolt is an effective strata control technique and is the key to ensure the stability of anchorage and roadway. Based on the performances of high energy storage tension rock bolts in different rock properties, this study proposed a constitutive model to describe the energy balance of anchor under uniaxial compression. UDEC was used to simulate the behaviour of anchor in coal under uniaxial compression and the results were analysed to study the rock mechanical properties, degree of damage and energy evolution. Simulation results showed that tension rock bolts can improve the mechanical properties and energy storage capacities of anchor. The energy evolution was divided into three stages: i) the external work was stored in the form of elastic strain energy (Ue) in the anchor prior to the yielding strength; ii) the elastic strain energy reached its maximum near the peak strength; iii) Energy was dissipated from fracture friction (Wf ), plastic deformation (Wp) and acoustic emission (Ur) during post-peak stage. The installation of tension rock bolts was more suitable for medium hard rock (e.g. sandy mudstone), whereas it was not effective for hard rock (e.g. sandstone).
Data from: Effect of storage condition on the physicochemical properties of corn-wheat starch / zein edible bilayer films
<p>The functional properties of biopolymer-based film packaging materials are susceptible to external storage conditions. The effects of different storage temperature, relative humidity (RH) and duration on the apparent form, barrier properties, mechanical properties and microstructure of corn-wheat starch/zein bilayer films were studied. From 0 to 150 d, storage temperature and RH, but not storage time, affected the appearance and colour of the bilayer films. The increase in haze of the bilayer films stored at 25°C was much greater than that at low temperatures. With increased storage time, the moisture content first increased and then decreased, while the water resistance and oxygen barrier properties of the bilayer films worsened. After 150 d, the bilayer film stored at 25°C with 54% RH had better water resistance properties. The oxygen barrier properties of the bilayer film stored at 25°C with 43% RH were preferable to those of other groups because the peroxide value of vegetable oil packed in the former bilayer film was the lowest. The tensile strength of bilayer films stored at 25°C with RH of 43%, 54%, and 65% decreased, but were still better than those stored at low temperatures (-17°C, 4°C), which were tough due to their high elongation at break. SEM results showed tight bonds between the bilayer films, and the network structure inside the films disappeared and reappeared during storage. The cross-sectional compactness changed, and there was no film separation after 150 d.</p>
Data from: Effects of condition and sperm competition risk on sperm allocation and storage in neriid flies
<p>Ejaculate traits can be sexually selected and often exhibit heightened condition-dependence. However, the influence of sperm competition risk in tandem with condition-dependent ejaculate allocation strategies is relatively unstudied. Because ejaculates are costly to produce, high-condition males may be expected to invest more in ejaculates when sperm competition risk is greater. We examined the condition-dependence of ejaculate size by manipulating nutrient concentration in the juvenile (larval) diet of the neriid fly Telostylinus angusticollis. Using a fully factorial design we also examined the effects of perceived sperm competition risk (manipulated by allowing males to mate first or second) on the quantity of ejaculate transferred and stored in the three spermathecae of the female reproductive tract. To differentiate male ejaculates, we fed males non-toxic rhodamine fluorophores (which bind to proteins in the body) prior to mating, labelling their sperm red or green. We found that high-condition males initiated mating more quickly and, when mating second, transferred more ejaculate to both of the female's posterior spermathecae. This suggests that males allocate ejaculates strategically, with high-condition males elevating their ejaculate investment only when facing sperm competition. More broadly, our findings suggest that ejaculate allocation strategies can incorporate variation in both condition and perceived risk of sperm competition.</p>

Different photoperiodic responses in diapause induction can promote the maintenance of genetic diversity via the storage effect in Daphnia pulex
<p>Understanding mechanisms that promote the maintenance of biodiversity (genetic and species diversity) has been a central topic in evolution and ecology. Previous studies have revealed that dormancy can contribute to coexistence of competing genotypes or species in fluctuating environments via the storage effect. However, they tended to focus on differences in reproductive success (e.g., seed yield) and diapause termination (e.g., germination) timing. Here we tested whether different photoperiodic responses in diapause induction can promote coexistence of two parthenogenetic (asexual) genotypes of <em>Daphnia pulex </em>in Lake Fukami-ike, Japan. Through laboratory experiments, we confirmed that short day length and low food availability induced the production of diapausing eggs. Furthermore, we found that one genotype tended to produce diapausing eggs in broader environmental conditions than the other. Terminating parthenogenetic reproduction earlier decreases total clonal production, but the early-diapausing genotype becomes advantageous by assuring reproduction in "short" years where winter arrival is earlier than usual. Empirically parameterized theoretical analyses suggested that different photoperiodic responses can promote coexistence via the storage effect with fluctuations of the growing season length. Therefore, timing of diapause induction may be as important as diapause termination timing for promoting the maintenance of genetic diversity in fluctuating environments.</p>
