title: New remains of the armored dinosaur <i>Patagopelta cristata</i> Riguetti et al. 2022 (Ornithischia, Parankylosauria) from the Late Cretaceous of Patagonia, Argentina

description: The fossil record of Southern Hemisphere thyreophorans has expanded significantly in recent years. Among notable discoveries is the armoured dinosaur <i>Patagopelta cristata</i>, from Maastrichtian beds in northeastern Patagonia. This taxon was described from disarticulated elements collected at ‘Salitral Moreno’ (Río Negro, Argentina), with a cervical half-ring designated as the holotype and additional materials from multiple individuals referred to it. However, the precise geographical provenance of these remains within the area is unknown. This contribution describes newly collected armoured dinosaur material from Salitral Moreno that provides key anatomical and phylogenetic information. The new material, comprising cranial elements, partial limbs, vertebrae, sacrum, pelvis, and osteoderms, is assigned to <i>Patagopelta</i>. These remains reveal a relatively plesiomorphic pelvis and an armoured tail resembling that of the parankylosaur Stegouros. Incorporation of these data into a comprehensive phylogenetic analysis places <i>Patagopelta</i> within Parankylosauria, closer to Antarctopelta and Kunbarrasaurus than to Stegouros. These findings support the interpretation of parankylosaurs as a distinct Southern Hemisphere radiation of thyreophorans, exhibiting greater body size, morphological, and likely ecological diversity than previously recognised.

title: Numerical simulation of enhanced sludge drying via granulation and optimized dynamic transport

description: Aiming to address the issues of low efficiency and poor uniformity in sludge drying processes, this study systematically investigates the effects of sludge granulation parameters and conveying control methods on drying characteristics. Results show that sludge thickness, spacing, and length significantly affect drying performance by altering the specific surface area of the material. A large specific surface area improves contact between sludge and hot air, thereby enhancing the drying rate. Optimal dehumidification and uniformity were achieved when the sludge spacing was 20 mm, thickness was 10 mm, and length was 70 mm. Conveying speed also has a significant impact on drying efficiency, as its adjustment changes the trend of moisture content variation and the airflow distribution within the drying chamber. The best performance was observed at a conveying speed of 0.053 mm/s, where the moisture content was reduced to 10% in 92 min. In addition, rational conveying control can suppress the adverse effects of vortices at the bottom of the drying chamber, improving overall efficiency. Stagnation time and position are also key factors for drying uniformity. A staggered stagnation strategy, with 30 min of stagnation for the upper left and lower right layers, reduced the standard deviation of moisture content from 12.4% to 5.9%, significantly improving consistency and product quality. The specific energy consumption decreased from 1.04 MJ/kg to 0.71 MJ/kg, representing a reduction of about 31.7%. This study provides valuable insights into improving sludge drying performance through granulation parameter optimization and dynamic conveying control.

title: Synthetic urban gamma-ray spectra for training spectral detection and identification models

description: This dataset contains training, validation, and testing data that consist
 of individual gamma-ray spectra from a synthetic urban radiological
 dataset. The spectra were generated by the Radiological Detection and
 Identification (RADAI) project and are from a simulated 2x4x16"
 NaI(Tl) detector traveling down a street in a simulated urban area. The
 background consists of realistic benchmarked terrestrial (K-40, U-238
 series, Th-232 series), fallout (Cs-137), rain (Pb-214 and Bi-214), and
 cosmic gamma-ray events. The 24 anomalous sources are simulated point-like
 sources of various types, including enhanced naturally occurring
 radioactive material (NORM), medical isotopes, industrial isotopes, and
 special nuclear material (SNM). All simulations are performed in 3-D, so
 the effects of scattering from nearby objects and shielding by clutter are
 all included. The dataset is prepared so that all sources are encountered
 at a number of different locations and at a wide variety of strengths.
description: The dataset consists of individual gamma-ray spectra generated
 from a synthetic urban model by the Radiological Detection and
 Identification (RADAI) project. The spectra are not continuous in time,
 and some are background-only while others contain a single anomalous
 source of any of 24 kinds. The data were generated by random selections of
 spectra from over 100 hours of data. Some high signal-to-noise (SNR)
 source encounters were in the dataset, and their strengths were randomly
 downsampled using binomial selection to cover SNR ranges of orders of
 magnitude for each source. The tools used to generate this dataset from
 the larger dataset are contained in the RADAI code repository (https://gitlab.com/lbl-anp/radai/radai).
description: The dataset is stored in a single HDF5 file. Global attributes
 such as the spectral bin edges, integration time, and spectrum label names
 are provided as HDF5 datasets and attributes, and the training,
 validation, and testing data are stored in data groups. Each set contains
 the spectra (<strong>X</strong>), the same spectra with
 background-tagged events only (<strong>X_b</strong>), the same
 spectra with source-tagged events only (<strong>X_s</strong>),
 the true source labels (<strong>y_label</strong>), the
 fractional amount of gross counts from each source type
 (<strong>y_s_over_bs</strong>), and the gross-counts
 signal-to-noise ratio (SNR) of the sources if present
 (<strong>y_snr</strong>). The latter two datasets
 (<strong>y_s_over_bs</strong> and
 <strong>y_snr</strong>) are calculated from the other datasets
 and provided for convenience.

title: Data for: Intraspecific variation in dispersal probability and host quality shape nectar microbiomes

description: Filtering of epiphytic microbes can occur through plant traits and
 deterministic dispersal-mediated processes. This filtering can affect
 microbiome assembly yet their relative contribution to predictable
 variation in microbiome is poorly understood. We collected this data set
 to test the impact of host-plant filtering and dispersal on nectar
 microbiome presence, abundance, and composition. We inoculated bacteria
 and yeast into 30 plants across 4 phenotypically distinct cultivars of
 Epilobium canum. We compared the growth of inoculated communities to
 openly visited flowers from a subset of the same plants.  We
 found evidence of host-selection when we inoculated flowers with synthetic
 communities. However, the host-plants with the highest microbial densities
 when inoculated did not have the highest microbial densities when openly
 visited. Host plants predictably varied in the presence or absence of
 bacteria, which was correlated with pollen receipt, suggesting a role for
 deterministic dispersal.  These findings suggest that host
 filtering could drive plant microbiome assembly in tissues where species
 pools are large and dispersal is high.  However deterministic
 differences in microbial dispersal to hosts may be equally or more
 important when microbes rely on an animal vector, dispersal is low, or
 arrival order is important.

title: Wolverine denning behaviour and its implications for monitoring reproductive females

description: Knowledge about the number of reproductive females is important for
 monitoring population dynamics, and can be critical for managing
 human-wildlife conflicts. For wolverines (Gulo gulo), counts of
 reproductive females is the basis for estimates of population size in
 Scandinavia, as well as a key measure for compensation payments to Sámi
 reindeer-herders in Sweden. However, documenting wolverine reproductive
 events in the field is challenging and requires knowledge of female
 denning behaviour. Furthermore, females may shift den sites, presenting
 difficulties in determining whether two den sites belong to the same or
 two neighbouring females. In this study, we used data from 18 GPS-collared
 wolverine females, monitored intensively during the denning season
 (February 15 – May 31) in 2004–2014, to provide baseline information on
 denning behaviour. We documented reproductive events in 32 of 54 potential
 denning seasons and identified a total of 245 den sites. Females used
 8.8±8.5 (mean±SD) den sites per denning season (median=6, range: 1–28).
 The number of den site shifts, the distance between subsequent den sites,
 and the time and distance females spent away from a den site increased
 during the denning season, while distances between neighbouring females’
 den sites remained constant. From late April, the distance between
 consecutive den sites used by the same female overlapped with distances
 between neighbouring females’ den sites, resulting in increased
 uncertainty regarding whether two den sites belonged to one or two
 females. Using Bayesian modelling, we calculated probabilities that two
 den sites belonged to the same female or neighbouring females, conditional
 on the time of season and the distance between den sites. These findings
 will allow the monitoring program to adapt its methods for determining if
 multiple den sites belong to one or two reproductive events, using
 seasonally-dynamic threshold based on an understanding of wolverine
 denning behaviour.

title: Data for: Patrolling the border: billfish exploit the hypoxic boundary created by the world's largest oxygen minimum zone

description: Pelagic predators must contend with low prey densities that are
 irregularly distributed and dynamic in space and time. Based on satellite
 imagery and telemetry data, many pelagic predators will concentrate
 horizontal movements on ephemeral surface fronts—gradients between water
 masses—because of enhanced local productivity and increased forage fish
 densities. Vertical fronts (e.g., thermoclines, oxyclines) can be
 spatially and temporally persistent and aggregate lower trophic level and
 diel vertically migrating organisms due to sharp changes in water density
 or available oxygen. Thus, vertical fronts represent a stable and
 potentially energy-rich habitat feature for diving pelagic predators but
 remain little explored in their capacity to enhance foraging
 opportunities. Here, we use a novel suite of high-resolution biologging
 data, including in situ derived oxygen saturation and video, to document
 how two top predators in the pelagic ecosystem exploit the vertical fronts
 created by the oxygen minimum zone of the eastern tropical Pacific. Prey
 search behavior was dependent on dive shape, and significantly increased
 near the thermocline and hypoxic boundary for blue marlin (Makaira
 nigricans) and sailfish (Istiophorus platypterus), respectively. Further,
 we identify a behavior not yet reported for pelagic predators, whereby the
 predator repeatedly dives below the thermocline and hypoxic boundary (and
 by extension, below the prey). We hypothesize this behavior is used to
 ambush prey concentrated at the boundaries from below. We describe how
 habitat fronts created by low-oxygen environments can influence pelagic
 ecosystems, which will become increasingly important to understand in the
 context of global change and expanding oxygen minimum zones. We anticipate
 that our findings are shared among many pelagic predators where strong
 vertical fronts occur, and additional high-resolution tagging is warranted
 to confirm this.

title: Herbaceous vegetation responses to experimental fire in savannas and forests depend on biome and climate

description: Fire-vegetation feedbacks potentially maintain global savanna and forest
 distributions. Accordingly, vegetation in savanna and forest ecosystems
 should have differential responses to fire, but fire response data for
 herbaceous vegetation has yet to be synthesized across biomes. Here, we
 examined herbaceous vegetation responses to experimental fire at 30 sites
 spanning four continents. Across a variety of metrics, herbaceous
 vegetation increased in abundance where fire was applied, with larger
 responses to fire in wetter and in cooler and/or less seasonal systems.
 Compared to forests, savannas were associated with a 4.8 (±0.4) times
 larger difference in burned versus unburned herbaceous vegetation
 abundance. In particular, grass cover decreased with fire exclusion in
 savannas, largely via decreases in C4 grass cover, whereas changes in fire
 frequency had a relatively weak effect on grass cover in forests. These
 differential responses underscore the importance of fire for maintaining
 the vegetation structure of savannas and forests.
