Genetic erosion in an endangered desert fish during a multi-decadal megadrought despite long-term supportive breeding
<p>Human water use combined with a recent megadrought have reduced river and stream flow through the Southwestern United States and led to periodic drying of formerly perennial river segments. Reductions in snowmelt runoff and increased extent of drying collectively threaten short-lived, obligate aquatic species, including the endangered Rio Grande Silvery Minnow. This species experiences 'boom-and-bust' population dynamics where large fluctuations in abundance are expected to lower estimates of effective population size and erode genetic diversity over time. Rates of diversity loss are also affected by additions of hatchery-origin fish used to supplement the wild population. We leveraged demographic and genetic data from wild and hatchery individuals to understand the relationship of genetic diversity and effective population size to abundance over the last two decades. Genetic diversity was low during the early 2000s, but diversity and demographic metrics stabilized after the hatchery program was initiated and environmental conditions improved. Yet, from 2017 onward, allelic diversity declined (Cohen's <em>d</em>=1.34) and remains low despite hatchery stocking and brief wild population recovery. Across the time series, single-sample estimates of effective population size (N<sub>eD</sub>) were positively associated (<em>r</em>=0.53) with wild/total abundance, but as the proportion of hatchery-origin spawners increased, N<sub>eD</sub> was reduced (N<sub>eD</sub> <em>r</em>= -0.55). Megadrought limits wild spawner abundance and precludes refreshment of hatchery brood stocks with wild fish, hence we predict an increasingly hatchery-dominated population, and accelerated loss of genetic diversity despite supplementation. We recommend an adaptive and accelerated management plan that integrates river flow management and hatchery operations to slow the pace of genetic diversity loss exacerbated by megadrought.</p>
Long-term variations of ambient volatile organic compounds (VOCs) from 2016 to 2020 in Beijing, China
<p>Ambient volatile organic compounds (VOCs) are crucial precursors for the formation of secondary organic aerosol (SOA) and ozone (O<sub>3</sub>). We have conducted in-situ observations and compiled a comprehensive dataset of ambient volatile organic compound (VOC) compositions and concentrations in Beijing, China, spanning the period from 2016 to 2020. The dataset covers a wide range of VOC species including 29 alkanes, 11 alkenes, 1 alkyne, 16 aromatics, 28 halohydrocarbons, 13 oxygenated VOCs (OVOCs), and 1 nitrogenous VOC (acetonitrile). The presentation and analysis of this dataset is available in a paper submitted to Earth System Science Data (Simon et al, in prep). The findings and analysis of this dataset have been documented in a paper that has been submitted to Earth System Science Data (Liu et al., in prep).</p> <p>If you use the dataset for related scientific research, please cite the corresponding reference:</p> <p> Liu et al (in prep); Long-term variations of ambient volatile organic compounds (VOCs) from 2016 to 2020 in Beijing, China; Earth System Science Data.</p>
Long-term livestock exclusion increases plant richness and reproductive capacity in arid woodlands
<p><strong>Aim</strong></p> <p>Herbivore exclusion is implemented globally to recover ecosystems from grazing by introduced and native herbivores, but evidence for large-scale biodiversity benefits is inconsistent in arid ecosystems. We examined the effects of livestock exclusion on dryland plant richness and reproductive capacity.</p> <p><strong>Location</strong></p> <p>Central Australia.</p> <p><strong>Methods</strong></p> <p>We collected data on plant species richness and seeding (reproductive capacity), rainfall, vegetation productivity and cover, soil health, and herbivore grazing intensity from 68 sites across 6500 km<sup>2</sup> of arid Georgina gidgee (<em>Acacia</em> <em>georginae</em>) woodlands between 2017 and 2020. Sites were on an actively grazed cattle station and two destocked conservation reserves. We used structural equation modelling to examine indirect (via soil or vegetation modification) versus direct (herbivory) effects of grazing intensity by two introduced herbivores (cattle, camels) and a native herbivore (red kangaroo), on seasonal plant species richness and seeding.</p> <p><strong>Results</strong></p> <p>Soil health and rainfall were the strongest drivers of variation in richness and seeding. Cattle and camel grazing indirectly led to lower seasonal richness and seeding by reducing soil health. Kangaroos had a small but negative direct impact on richness, but no impact on soil health. Both introduced and native herbivores reduced annual chenopod shrub richness and seeding, whereas only cattle directly reduced perennial shrub richness and seeding. Camels indirectly reduced perennial shrub richness by impacting shrub abundance. Introduced herbivores reduced native grass richness and seeding indirectly via impacts on soil health, whereas forbs responded positively to cattle and camel activity.</p> <p><strong>Main conclusion</strong></p> <p>Considering indirect impacts improves evaluations of the effects of disturbances on biodiversity, as focusing only on direct effects can mask critical mechanisms of change. Our results indicate substantial biodiversity benefits from excluding livestock and controlling camels in drylands. Reducing introduced herbivore impacts will improve soil and vegetation condition, ensure reproduction and seasonal persistence of species, and protect native plant diversity.</p>
Data for: Cooperative assembly confers regulatory specificity and long-term genetic circuit stability
<p>A ubiquitous feature of eukaryotic transcriptional regulation is cooperative self-assembly between transcription factors (TFs) and DNA cis-regulatory motifs. It is thought that this strategy enables specific regulatory connections to be formed in gene networks between otherwise weakly-interacting, low-specificity molecular components. Here, using synthetic gene circuits constructed in yeast, we find that high regulatory specificity can emerge from cooperative, multivalent interactions among artificial zinc finger-based TFs. We show that circuits 'wired' using the strategy of cooperative TF assembly are effectively insulated from aberrant misregulation of the host cell genome. As we demonstrate in experiments and mathematical models, this mechanism is sufficient to rescue circuit-driven fitness defects, resulting in genetic and functional stability of circuits in long-termcontinuous culture. Our naturally-inspired approach offers a simple, generalizable means for building high-fidelity, evolutionarily robust gene circuits that can be scaled to a wide range of host organisms and applications.</p>
Project BioDyn: compilation of long-term (>20yrs) community timeseries data from terrestrial and freshwater realms
<p>The given dataset was compiled for n=2668 communities (242 study IDs in total, see the metadata file) across terrestrial and freshwater realms (terrestrial birds: n=1259, invertebrates: n=124, plants: n=435, and mammals: n=136, freshwater fish: n=587, invertebrates: n=112, and phytoplankton: n=15). Community timeseries include species-level abundance (or biomass in 15% of cases) and a minimum of 20 years sampled. We have compiled this data and used it for the first time to analyze how community stability and its drivers (species richness, overall synchrony, and tail-dependent synchrony) would differ across realms.</p>
Hemostatic system in Takotsubo patients at long-term follow-up: A hidden activation?
<p>This record contains raw data related to the article “Hemostatic system in Takotsubo patients at long-term follow-up: A hidden activation?”</p> <p><strong>Background: </strong>Takotsubo cardiomyopathy (TTS) has long been considered a benign condition, despite recurrent events and long-term adverse outcomes are often reported. Endothelial damage, blood hyperviscosity, and platelet activation described in acute phase persist in long-term follow-up; however, TTS pathophysiology is still not fully understood. Here, we explored the hemostatic system at a median of 3.1 years after TTS to uncover additional long-lasting changes in these patients.</p> <p><strong>Methods: </strong>We assessed hemostatic parameters in women with TTS (n = 23) or coronary artery disease (CAD; n = 31) and in control women (n = 26) age-matched, by thromboelastographic analysis, prothrombin time (PT) and partial thromboplastin time (aPTT) coagulation assays and microparticle exposing Tissue Factor (MP-TF). Functional fibrinogen and fibrin polymerization were analyzed by Clauss method and spectrophotometry, respectively. Platelet reactivity was evaluated by light transmission aggregometry, whereas plasminogen activator inhibitor-1 (PAI-1) and brain-derived neurotrophic factor (BDNF) were measured by ELISA kit.</p> <p><strong>Results: </strong>Compared with control subjects, TTS patients exhibit an accelerated clot formation, higher percentage of fibrin polymerization and higher PAI-1 levels. Compared with CAD, TTS patients showed sustained residual platelet activation but decreased functional fibrinogen, fibrin polymerization and MP-TF levels, prolonged aPTT and a marked BDNF increase.</p> <p><strong>Conclusions: </strong>The long-term activation of hemostatic system observed in TTS patients compared to control subjects suggests a persistent humoral abnormality that may be related to the propensity for TTS recurrence. The higher residual platelet activity observed in TTS than in CAD patients invites investigation on TTS-tailored antiplatelet therapy potentially needed to prevent TTS adverse outcomes.</p>
Data from: Evolution of a cross-feeding interaction following a key innovation in a long-term evolution experiment with Escherichia coli
<p>The evolution of a novel trait can profoundly change an organism's effects on its environment, which can in turn affect the further evolution of that organism and any coexisting organisms. We examine these effects and feedbacks following the evolution of a novel function in the Long-Term Evolution Experiment (LTEE) with <em>Escherichia</em> <em>coli</em>. A characteristic feature of <em>E. coli</em> is its inability to grow aerobically on citrate (Cit<sup>−</sup>). Nonetheless, a Cit<sup>+</sup> variant with this capacity evolved in one LTEE population after 31,000 generations. The Cit<sup>+</sup>clade then coexisted stably with another clade that retained the ancestral Cit<sup>−</sup> phenotype. This coexistence was shaped by the evolution of a cross-feeding relationship based on C<sub>4</sub>-dicarboxylic acids, particularly succinate, fumarate, and malate, that the Cit<sup>+</sup> variants release into the medium. Both the Cit<sup>−</sup> and Cit<sup>+</sup> cells evolved to grow on these excreted resources. The evolution of aerobic growth on citrate thus led to a transition from an ecosystem based on a single limiting resource, glucose, to one with at least five resources that were either shared or partitioned between the two coexisting clades. Our findings show that evolutionary novelties can change environmental conditions in ways that facilitate diversity by altering ecosystem structure and the evolutionary trajectories of coexisting lineages.</p>
Long-term ecological responses of a lowland dipterocarp forest to climate changes and nutrient availability at Bulusan Lake
<p>This data publication encompasses the datasets generated in a study focusing on reconstructing ecological responses to climatic and nutrient availability changes during the late Holocene in northern Philippines. The data comes from samples taken from sediment cores retrieved from Bulusan Lake, located on Luzon Island, Philippines, in March 2013. In these samples, we analyzed fossil pollen and spores (a proxy for plant taxa abundance), charcoal (a proxy for fire activity), stable carbon isotopic composition of terrestrial-lipid biomarkers (a proxy for vegetation cover), stable nitrogen and phosphate isotope composition of bulk sediments, and elemental composition of sediment cores at a high resolution (proxies for nutrient availability and volcanic activity). The dataset also includes links to records generated in a previous study on the same sediments (Prohaska <em>et al.</em> 2023), where we measured the stable hydrogen isotopic composition of terrestrial-lipid biomarkers to reconstruct past hydrological conditions, as well as the magnetic susceptibility record and AMS dates of plant macrofossils to calculate sediment accumulation ages. The data generation spanned the period from April 2013 to September 2020, and the data files are provided in Excel spreadsheet format.</p>

Long-term warming of a forest soil reduces microbial biomass and its carbon and nitrogen use efficiencies
<p>Global warming impacts biogeochemical cycles in terrestrial ecosystems, but it is still unclear how the simultaneous cycling of carbon (C) and nitrogen (N) in soils could be affected in the longer-term. Here, we evaluated how 14 years of soil warming (+4°C) affected the soil C and N cycle across different soil depths and seasons in a temperate mountain forest. We used H<sub>2</sub><sup>18</sup>O incorporation into DNA and <sup>15</sup>N isotope pool dilution techniques to determine gross rates of C and N transformation processes. Our data showed different warming effects on soil C and N cycling, and these were consistent across soil depths and seasons. Warming decreased microbial biomass C (−22%), but at the same time increased microbial biomass-specific growth (+25%) and respiration (+39%), the potential activity of β-glucosidase (+31%), and microbial turnover (+14%). Warming reduced gross rates of protein depolymerization (−19%), but stimulated gross N mineralization (+63%) and the potential activities of N-acetylglucosaminidase (+106%) and leucine-aminopeptidase (+46%), and had no impact on gross nitrification (+1%). Microbial C and N use efficiencies were both lower in the warming treatment (−15% and −17%, respectively). Overall, our results suggest that long-term warming drives soil microbes to incorporate less C and N into their biomass (and necromass), and to release more inorganic C and N to the environment, causing lower soil C and N storage in this forest, as indicated by lower soil C and total N contents. The decreases in microbial CUE and NUE were likely triggered by increasing microbial P constraints in warmed soils, limiting anabolic processes and microbial growth and promoting pervasive losses of C and N from the soil.</p>

The dynamic matrix predicts population response to long-term experimental forest fragmentation
<div><strong>Context</strong></div> <div> </div> <div>Earth's forests are fragmented. Species' long-term persistence depends on their conservation in fragmented landscapes with remnants embedded in a matrix of human land use. This matrix influences species' persistence in fragments by determining their degree of isolation and the extent to which edge effects alter habitat. Matrix habitat is often dynamic, so its impact on persistence of remnant species changes over time.</div> <div> </div> <div><strong>Objectives</strong></div> <div> </div> <div>Previous research showed that the abundance response of predatory beetle species to matrix habitat predicted their response in fragments with a log-response ratio of about 0.5. When abundance declined in the matrix, there was a smaller but predictable decline in fragments. However, the predictive utility of a fragment:matrix log-response ratio needs testing with functionally different species, more detailed data, and a focus on mechanism.</div> <div> </div> <div><strong>Methods</strong></div> <div> </div> <div>In the Wog Wog habitat fragmentation experiment, we follow a detritivorous amphipod 27 years after forest fragmentation.</div> <div> </div> <div><strong>Results</strong></div> <div> </div> <div>The amphipod's response in habitat fragments was predicted by its response in the matrix with a log-response ratio of about 0.5, similar to predatory beetles. The amphipod's response was explained by its abiotic niche. The amphipod's short-term response did not predict its long-term response.</div> <div> </div> <div><strong>Conclusions</strong></div> <div> </div> <div>The log-response ratio might generalize across the invertebrate food web. For two groups within the Wog Wog experiment, a species' dynamic response in matrix habitat predicted its persistence in fragments. Future work should explore the generality of this finding. With knowledge of projected land use of matrix habitat, a species' matrix response could be used for management planning.</div>

Mitochondrial responses to long-term and cyclic hypoxia depend on the oxidized fuel in a hypoxia-tolerant marine bivalve Crassostrea gigas
<p>These are the metadata for a publication "Mitochondrial responses to long-term and cyclic hypoxia depend on the oxidized fuel in a hypoxia-tolerant marine bivalve <em>Crassostrea gigas"</em> under consideration for publication in the Scientific reports. Sessile benthic organisms like oysters inhabits intertidal zone transitioning between aquatic and terrestrial condition during tidal movements exposing the organisms to alternating hypoxia and reoxygenation (H/R) episodes thereby altering the respiratory chain activities and metabolome compositions. Our study investigated the effects of constant long-term H/R stress (90 min at ~0% O<sub>2, </sub>and 10 min reoxygenation) and constant cyclic H/R stress (5 cycles of 15 min at ~0% O<sub>2, </sub>and 10 min reoxygenation) on isolated mitochondria from the gill and the digestive gland of <em>C. gigas</em> respiring on different substrates (pyruvate, palmitate, and succinate). Both gill and the digestive gland mitochondria exposed to constant long-term H/R suppressed OXPHOS respiration especially during Complex I oxidation with no change in ROS efflux but an increase FEL. In the gill mitochondria oxidizing Complex I substrates, exposure to constant cyclic H/R prompted a significant drop after the first H/R cycle. In contrast, succinate-driven respiration only showed significant decline after the fifth H/R cycle. ROS efflux and FEL however saw little to no change after constant cyclic H/R. This observation from our study further suggests succinate as a potential stress fuel under H/R stress and might assist in post-hypoxic recovery of oysters mitigating oxidative stress and supporting rapid ATP re-synthesis during oxygen fluctuations such as commonly observed in intertidal zones. Additionally, our study revealed that constant long-term hypoxia is more damaging than constant cyclic hypoxia. </p>

Kenai Mountains to Sea: Using Thermal Infrared Imagery to Implement Long-Term Salmon Conservation - thermal imagery data set
<p>Cook Inletkeeper contracted NV5 Geospatial (formerly, Quantum Spatial Incorporated) to collect thermal infrared (TIR) during the summer of 2020 along four streams on the Kenai Peninsula in southern Alaska: Beaver Creek, Crooked Creek, Funny River, and Moose River under a project name “Kenai Rivers”. All streams were contracted to be flown in the summer of 2020 and during the afternoon hours in order to maximize the thermal contrast between the river’s water and the banks. The survey extends for a total length of 59.1 km miles of the Kenai Rivers. The Data were collected to aid the Cook Inletkeeper team to identify the spatial variability in surface temperatures as well as thermal influence of point sources, tributaries, and surface springs. The data will also be used to identify high-value habitats for the salmonids population within the four streams.</p> <p>Note: These data and related items of information have not been formally disseminated by NOAA and do not represent any agency determination, view, or policy.</p> <p>Funding for this project came, in part, from the Alaska Sustainable Salmon Fund (AKSSF Project #53003).</p>
Selecting exceptional tropical tree species to increase long-term carbon storage
<ol> <li><span>With rising atmospheric CO<sub>2</sub> concentrations, strategies for greater carbon sequestration and long-term storage are urgently needed. Current reforestation schemes typically use fast-growing tree species with low wood density, limiting the amount of carbon stored. In most tropical forests, there are native species with relatively fast growth rates, high wood density, and low mortality rates that also achieve large adult size — 'exceptional species.'</span></li> <li> <span>We present a simulated assessment of the carbon sequestration potential using these exceptional species selected based on a given set of criteria in </span><span>assisted secondary succession in the Neotropics.</span> </li> <li> <span>In our example, our selected exceptional species could add </span><span>up to 16.2 Mg C/ha of sequestered carbon in secondary wet forests at maturity.</span> </li> <li><span><em>Synthesis and applications</em>. By increasing the representation of exceptional species in reforestation efforts, we could potentially boost long-term carbon storage in reforestation projects focused on carbon sequestration. However, our approach is not a substitute for protecting existing old primary forests and reforested lands plus reducing deforestation and emissions.</span></li> </ol>
Data from: Contrasting impacts of short- and long-term large herbivore exclusion on understory net CO2 exchange in a boreal forest
<p>Across boreal forests, trees are the main living biomass carbon (C) stock, but the understory vegetation can contribute significantly to the C cycling and net forest carbon dioxide (CO<sub>2</sub>) balance. The patchy understory vegetation which consists of sunlit (i.e., lichen-like) and shaded habitats (i.e., dwarf shrub-like) is often altered by ungulate grazers. Grazers may influence understory CO<sub>2</sub> exchange, and consequently, the forest CO<sub>2</sub> balance. Grazing affects differently the biomass of slow growing lichens compared to the faster growing mosses and dwarf shrubs, and therefore the effects of grazing on CO<sub>2</sub> exchange in the patchy understory vegetation could vary temporally. We studied how excluding grazing for short- and long-term affects the CO<sub>2</sub> exchange and vegetation biomass in the understory of an oligotrophic Scots pine forest. We measured growing season (2019, 2020) CO<sub>2</sub> exchange across sunlit and shaded habitats inside fences that had excluded large grazers for 0–1 and 25–26 years and in the adjacent grazed area. In addition, we measured the height of understory vegetation. We found that short-term grazer exclusion increased ecosystem CO<sub>2</sub> source fluxes only in the shaded habitats. However, long-term exclusion of grazing decreased CO<sub>2</sub> net release regardless of the habitat type. Furthermore, grazer exclusion increased moss depth immediately which coincided with an abrupt intensification of CO<sub>2</sub> net release. Considering the impacts of grazing over both short- and long-term may help to forecast C fluxes more accurately which may be relevant for informed climate solutions regionally and even on a larger scale.</p>
TimeFISH: Long-term assessment of reef fish assemblages in a transition zone in the Southwestern Atlantic
<p>The TimeFish database provides the first public time-series dataset on reef fish assemblages in the Southwestern Atlantic (SWA), comprising 15 years of data (2007-2022) based on standardized Underwater Visual Censuses (UVCs). The rocky reefs covered by our dataset are influenced by pronounced seasonal cycles of ocean temperatures with warm tropical waters from the Brazil Current in the summer (~27°C) and colder waters from the La Plata River Plume discharge and upwelling from the South Atlantic Central Water in the winter (~18°C). These oceanographic conditions characterize this area as the southernmost tropical-subtropical climatic transition zone in the Atlantic Ocean. As a result, reef fish assemblages comprise both tropical and subtropical species. All records included in TimeFish were collected using UVCs, a non-destructive method that allows the estimation of fish species richness, abundance, and body size distributions. UVCs were performed through 40 m2 belt transects by scuba diving in nine locations along the southern Brazilian coast (25°S – 29°S). Four of these locations lie within the boundaries of the no-entry Arvoredo Marine Biological Reserve, where fishing and recreational activities are forbidden, and the remaining locations are unprotected from these activities. During each belt transect, a diver swam at a constant depth above and parallel to the reef, identifying fish species, counting the number of individuals, and estimating the total body length (Lt in cm) of all detected individuals. All fish individuals in the water column (up to 2 m above the substratum) and at the bottom were targeted. A total of 202,965 individuals belonging to 163 reef fish species and 53 families were recorded across 1,857 UVCs. All survey campaigns were funded by either public or mixed capital (private-public) sources, including seven grants from the Brazilian federal and Santa Catarina state government. Part of the data have already been used in multiple MSc and Ph.D. theses and scientific articles. TimeFISH represents an important contribution for future studies aiming to examine temporal and spatial variations of reef fish assemblages in transition zones.

Environmental heterogeneity on landslide slopes affects the long-term recoveries of forest ecosystem components
<p>Landslides are a common disturbance in mountainous areas of the world. Transporting and accumulating landslide debris, i.e., disturbance legacies, such as coarse woody debris (CWD), vegetation patches, and surface soils, generate a heterogeneous environment along slopes (zones), which are suggested to affect forest recovery. However, the long-term changes in forest ecosystems after landslides remain unknown, particularly zone-dependent change patterns. We aimed to reveal the differences in the changes in live trees, understory vegetation, CWD, and soils among zones by surveying forests with landslide ages (years since the landslide) ranging from 3 to 74 years and reference stands. The increase in live tree aboveground biomass occurred at a faster rate at the lower part of the slopes where the disturbance legacies were rich and surface soils were stabilized due to the smaller slope angle. Chronological patterns of understory vegetation amounts were determined by the differences in disturbance legacy richness and the timing of subsequent canopy closure. The amounts and decay-class diversity of CWD were determined by the differences in legacy richness and mortality through stand development. These zone-dependent chronological changes influenced litter production and determined the recovery rates of surface soil carbon and nitrogen stocks. The increase in the dominance rates of forest herbaceous species was faster in the lower part of the slopes due to the faster surface soil development and canopy closure. Our results illustrate that long-term forest ecosystem succession and recovery after landslides occurs more rapidly at the lower parts than at the upper parts of slopes.</p>
