Dorsalistachya quadrisegmentorum - Dataset 1 – Three-dimensional reconstruction model (SPIERSView and VAXML format)
<p>Three-dimensional reconstruction model of <em>Dorsalistachya quadrisegmentorum</em> in SPIERSView and VAXML format.</p> <p>Notes:</p> <ol> <li>SPIERSView file (.SPV) models can conveniently be viewed using the SPIERSView software, freely available in both Windows and Mac versions from http://www.spiers‐software.org. However, note that low-performance computers may not possess a sufficiently powerful graphics card to render and rotate the model.</li> <li>VAXML file format models are saved as a ZIP-compressed VAXML datasets. VAXML uses one or more .STL files to define the geometry of objects that comprise the dataset, together with one .VAXML file that provides metadata on the dataset as a whole, and specifies how the .STL files should be put together. We recommend using the free SPIERS software to view this model format (http://spiers-software.org/). However, .STL files can be opened independently in several freely available software programs (e.g. MeshLab, Blender). Additional information on the VAXML format can be found here: http://spiers-software.org/VAXML.htm.</li> </ol>

Uribe-Rivera et al 2017 DataSet: High resolution bioclimatic layers for southwest of South America for three recent past periods (1970, 1990 and 2010)
<p>These files were generated as part of the article "Dispersal and extrapolation on the accuracy of temporal predictions from distribution models for the Darwin’s frog" (Uribe-Rivera et al. 2017; accepted in Ecological Applications)</p> <p>We used point data of meteorological stations between 34°-48°S and 70°-75°W, to generate new climatic surfaces for three recent past periods (1970; 1990; 2010). Meteorological data encompassed 293 weather stations, and were extracted from three databases: Dirección Meteorológica de Chile (DMC); Dirección General de Aguas de Chile (DGA); and the FAOClim-NET Agroclimatic database management system (FAO 2001), recording monthly records of mean daily minimum temperature, mean daily maximum temperature and total rainfall for 5-year periods (1965-1969 for 1970 climatic conditions; 1985-1989 for 1990 climatic conditions; and 2005-2009 for 2010 climatic conditions). For each period monthly mean values of each climatic variable were interpolated to generate surfaces using Anusplin v.4.4 (Hutchinson and Xu 2006), which applies the same algorithm used to derive the WorldClim bioclimatic surfaces (Hijmans et al. 2005). Interpolations were fitted following Pliscoff et al. (2014) at a ~1x1 Km resolution, with elevation as an independent variable using the GTOPO30 global digital elevation model (USGS, 1996). Because some weather stations do not have information for every month, we used the option of non-data of Anusplin. The quality of interpolations of climatic data was assessed calculating the Pearson correlation coefficient at the cell level between the monthly climatic values from the CRU-TS v3.10.01 Historic Climate Database for GIS (Climatic Research Unit - Time Series, 2012), and the monthly climatic values from the new climatic layers. Finally, surfaces of 19 bioclimatic variables were generated using the dismo package in R (Hijmans et al. 2014).</p> <p>All bioclimatic layers were uploaded in a single compressed ZIP file. Individual layers can be found inside it as georeferenced ASCII raster files, and nominated primarily by time period, and secundarily by the number of bioclimatic layer, following the worldclim nomenclature (http://www.worldclim.org/bioclim).</p>
Reconstructed Three-decade Global Fine-Grained Nighttime Light Dataset
<p>Nighttime light (NTL) is a foundational data source for studying human activities from a remote sensing perspective. This dataset from 1992 to 2021 is the first global long-term and fine-grained NTL observations. It represents a milestone in facilitating the study of human activities. It is created by a new super-resolution model DeepNTL which converts DMSP-OLS images into NPP-VIIRS images. Compared with baseline models, including RCAN, SwinIR and AutoEncoder, DeepNTL has the hightest accuracy and best generalization ability for untrained years. It provides a good extension of NPP-VIIRS to the early years, and the future annual NPP-VIIRS data can be directly appended to this dataset by users own. More information about the dataset can be found in the "read_me.txt" file. Technical details and evaluations are presented in our paper.

Code and data for: Shining a light on elusive lynx: density estimation of three Eurasian lynx populations in Ukraine and Belarus
<p class="MsoNormal"><span>The Eurasian lynx is a large carnivore widely distributed across Eurasia. However, our understanding of population status is heterogeneous across their range, with some populations isolated that are at risk of reduced genetic variation and a complete lack of information about others. In many European countries, Eurasian lynx are monitored through demographic studies crucial for their conservation and management. Even so, there are only rough and fragmented population assessments from Ukraine and Belarus, despite strict protection in both countries and their importance for lynx connectivity across Europe. We monitored lynx from October 2020 to March 2021 and used camera-trapping in combination with spatial capture-recapture (SCR) methods in a Bayesian Framework to provide the first SCR density estimation of three lynx populations across Ukraine and Belarus, including the Ukrainian Chornobyl Exclusion Zone, Southern Belarus, and the Ukrainian Carpathians. Our density estimates varied within our study areas ranging from 0.45 to 1.54 individuals/100 km<sup>2</sup>. This work</span><span> <span>provides a substantial scientific component to the overall understanding of lynx conservation for a region where only broad information is available </span></span><span>and opens the doors for further large-scale monitoring and trend assessments. </span><span>The crucial information we provide can greatly enhance the range-wide assessments of the status of this protected species. We also discuss the implications for Eurasian lynx conservation, despite the geopolitical realities impacting species monitoring in the region. Our work serves as a baseline, not only for future conservation interventions but also to evaluate the effects of disturbance and threats to these protected populations.</span></p>
Data from: Hair and plasma cortisol throughout the first three years of development in infant rhesus macaques, Macaca mulatta
<p>Cortisol expression has been demonstrated to have variation across development in rhesus macaques (Macaca mulatta). There exists contradictory evidence for the nature of this change, and age at which it occurs, across biological sample types. Consequently, we lack a cohesive understanding for cortisol concentrations across the development of a major human health translational model. We examined hair cortisol concentrations over the first three years of life for 49 mother-reared infant macaques from mixed-sex outdoor units at the California National Primate Research Center. For 48 of these subjects at infancy, one year, and two years, we obtained plasma cortisol samples for: response to a stressor, adjustment to prolonged stress, and response to dexamethasone injection. Hair cortisol concentrations decreased dramatically between three and ten months, followed by relative stability up to the final sampling event at around 34 months of age. Plasma cortisol showed within-year consistency, and consistency between infancy and year one. We document variability in the infant plasma cortisol samples, especially in percent change between samples one and two. Our plasma cortisol results indicate that infants possess the physiological capacity to effectively inhibit the release of cortisol when stimulated, as effectively as later responses in juveniles. Age-related changes in hair cortisol parallel findings indicating a large decline in the weeks following postparturation.</p>
Maritime international trade and bioinvasions: a three-year long survey of small mammals in Autonomous Port of Cotonou, Benin
<ol> <li>International trade has been favoring the dissemination of a wide panel of invasive alien species. Upstream prevention through the monitoring of entry points is identified as an appropriate strategy to achieve control of bioinvasions and their consequences. Maritime transports have been responsible for the introduction worldwide of exotic rodents that are major pests for crops and food stocks as well as reservoirs of many zoonotic pathogens. In order to limit further dissemination, the International Health Regulation constrains decision makers and socio-economic stakeholders to manage ship-mediated import/export of rodents within seaports. Unfortunately, eco-evolutionary insights into rodent introduction events that could guide preventive actions in seaports are very scarce.</li> <li>In order to bridge this gap, we here describe the results of a three-year-long survey of small mammals conducted in the Port of Cotonou, Benin, that aims at assessing the spatio-temporal distribution, diversity and relative abundance of invasive and native rodents.</li> <li>960 small mammal individuals were captured in nine within-seaport sites. We found (i) a marked predominance of invasive species (84% of the individuals belonging to <em>Mus</em> <em>musculus</em>, <em>Rattus</em> <em>rattus</em>, <em>R. norvegicus</em>), (ii) with native species (i.e., <em>Mastomys natalensis</em> and the shrew <em>Crocidura olivieri</em>) essentially restricted to peripheral non-industrial areas, as well as (iii) a fine-scale spatial segregation stable over time between the invasive Norway rats and house mice on the one hand, and the black rats and shrews on the other hand.</li> <li>Furthermore, trapping before and after two successive rodent anticoagulant-based control campaigns indicates that they were poorly efficient and that subsequent rodent recolonization occurs 6–12 months following intervention.</li> <li> <em>Synthesis and applications</em>: Our results are discussed in terms of ecological processes at play (e.g., interspecific interactions) and operational actions that may be implemented to improve rodent control (e.g., assessment of proper eradication units, environmental modifications) and to limit re-infestation (e.g., rat-proofing of moors and buildings).</li> </ol>

Fertilization can accelerate the pace of soil microbial community response to rest-grazing duration in the Three-river Source Region of China
<div> <div> <p><strong><span>Objectives</span></strong> </p> <p><span>Overgrazing leads to grassland degradation and productivity decline. Rest-grazing during the regreen-up period can quickly restore grassland and fertilization is a common restoration measure. Meanwhile, soil microorganisms are more sensitive indicators. Therefore, the experiment of rest-grazing time and fertilization was carried out to explore the response of soil microorganisms to rest-grazing time and fertilization measures. </span></p> <p><span><strong>Methods</strong> </span></p> <p><span>A field control experiment with rest-grazing time and fertilization as factors was conducted from the time when grass returned to green till the livestock moved to the summer pasture in Dawu Town of Maqin County.</span> <span>The primary treatment we established was the five</span> <span>rest-grazing times, including rest-grazing times of 20 days, 30 days, 40 days, 50 days, and traditional grazing was used as a check group. At the same time, the secondary treatment was nitrogen addition of 300 kg·hm<sup>-2</sup> in each primary treatment. </span></p> <p><span><strong>Results</strong> </span></p> <p><span>The results showed that: the total phospholipid fatty acid (total PLFA), actinomyces (Act) and arbuscular </span><span>mycorrhizal fungi (AMF) showed an ever-increasing biomass with the increase of rest-grazing time and the highest was at 50 days of rest-grazing, and they were all significantly higher than CK. In addition, soil microbial biomass carbon-nitrogen ratio (MBC/MBN)</span> <span>had a great influence on the change of microbial community. Applying nitrogen fertilizer can increase the maximum value of biomass of all PLFA groups and the biomass of all PLFA groups changed in an "inverted V" shape with the increase of rest-grazing time. Besides, </span><span>instead of MBC/MBN, NO<sub>3</sub><sup>-</sup>-N</span><span> was positively affected by the biomass of</span> <span>all PLFA groups, which actively regulated the trend of microbial functions. </span></p> <p><span><strong>Conclusions</strong> </span></p> <p><span>The longer rest-grazing time is more conducive to the biomass of all PLFA groups. However, applying nitrogen fertilizer could break this pattern, namely, the 30d rest-grazing would</span> <span>be beneficial to the biomass of all PLFA groups. These findings provide key information that rest-grazing during the regreen-up period is beneficial to all PLFA groups and </span><span>fertilization could change the response of microorganisms to rest-grazing</span><span>, which provides reference measures for the restoration of degraded alpine meadows.</span></p> </div> </div>
