title: Borrelia infection in bank voles Myodes glareolus is associated with specific DQB haplotypes which affect allelic divergence within individuals

description: The high polymorphism of Major Histocompatibility Complex (MHC) genes is
 generally considered to be a result of pathogen-mediated balancing
 selection. Such selection may operate in the form of heterozygote
 advantage, and/or through specific MHC allele–pathogen interactions.
 Specific MHC allele–pathogen interactions may promote polymorphism via
 negative frequency-dependent selection (NFDS), or selection that varies in
 time and/or space because of variability in the composition of the
 pathogen community (fluctuating selection; FS). In addition, divergent
 allele advantage (DAA) may act on top of these forms of balancing
 selection, explaining the high sequence divergence between MHC alleles.
 DAA has primarily been thought of as an extension of heterozygote
 advantage. However, DAA could also work in concert with
 NFDS though this is yet to be tested explicitly. To
 evaluate the importance of DAA in pathogen-mediated balancing selection,
 we surveyed allelic polymorphism of MHC class II DQB genes in wild bank
 voles (Myodes glareolus) and tested for associations between DQB
 haplotypes and infection by Borrelia afzelii, a tick-transmitted
 bacterium causing Lyme disease in humans. We found two significant
 associations between DQB haplotypes and infection status: one haplotype
 was associated with lower risk of infection (resistance), while another
 was associated with higher risk of infection (susceptibility).
 Interestingly, allelic divergence within individuals was higher for voles
 with the resistance haplotype compared to other voles. In contrast,
 allelic divergence was lower for voles with the susceptibility haplotype
 than other voles. The pattern of higher allelic divergence in individuals
 with the resistance haplotype is consistent with NFDS favouring divergent
 alleles in a natural population, hence selection where DAA works in
 concert with NFDS. 
description: We collected samples from live-trapped bank voles at Kalvs Mosse, east of Lund, southern Sweden (N 55 42.470’, E 13 29.216’). The MHC class II DQB genotype (MyglDQB) and infection status with the tick-transmitted bacterium <i>Borrelia afzelii</i> were screened in 527 individuals in the population data set and MHC class II DQB haplotypes were inferred in 12 families in the family data set, mothers and pups.
description: The population data set contains 57 columns (34 of which are MyglDQB-alleles) and the family data set contains 41 columns (36 of which are MyglDQB-alleles), detailed information about each column can be found in the published manuscript referenced above.

title: Plant traits of grass and legume species for flood resilience and N2O mitigation

description: Flooding threatens the functioning of managed grasslands by decreasing
 primary productivity and increasing nitrogen losses, notably as the potent
 greenhouse gas nitrous oxide (N2O). Sowing species with traits that
 promote flood resilience and mitigate flood-induced N2O emissions within
 these grasslands could safeguard their productivity while mitigating
 nitrogen losses. We tested how plant traits and resource acquisition
 strategies could predict flood resilience and N2O emissions of 12 common
 grassland species (eight grasses and four legumes) grown in field soil in
 monocultures in a 14-week greenhouse experiment. We found that grasses
 were more resistant to flooding, while legumes recovered better.
 Resource-conservative grass species had higher resistance, while
 resource-acquisitive grasses species recovered better. Resilient grass and
 legume species lowered cumulative N2O emissions. Grasses with lower
 inherent leaf and root δ13C (and legumes with lower root δ13C) lowered
 cumulative N2O emissions during and after the flood. Our results highlight
 the differing responses of grasses with contrasting resource acquisition
 strategies, and of legumes to flooding. Combining grasses and legumes
 based on their traits and resource acquisition strategies could increase
 the flood-resilience of managed grasslands, and their capability to
 mitigate flood-induced N2O emissions.

title: Behavior of Wild Tigers in Captivity at the Central Zoo, Nepal

description: This study investigates how visitor presence, sex, and duration of captivity influence the behavioral patterns and welfare indicators of rescued wild tigers (Panthera tigris) housed at the Central Zoo, Jawalakhel, Nepal. Using instantaneous scan sampling supported by continuous CCTV recordings across two seasons, we provide empirical evidence that visitor presence significantly alters activity budgets and increases stereotypic behaviors such as pacing and chewing. We further demonstrate sex-specific behavioral differences and distinct behavioral profiles associated with short-term versus long-term captivity.

title: Raw data: Local habitat factors and spatial connectivity jointly shape an urban insect community

description: As the world becomes more and more urbanized, it is increasingly important
 to understand the impacts of urban landscapes on biodiversity.
 Urbanization can change local habitat factors and decrease connectivity
 among local habitats, with major impacts on the structure of natural food
 webs. However, most studies have focused on single species, or compared
 rural to urban habitats, which do not inform us on how to design and
 manage cities to optimize biodiversity. To understand the local and
 spatial drivers of ecological communities within urban landscapes, we
 assessed the relative impact of local habitat factors (sunlight exposure
 and leaf litter) and spatial connectivity on an oak-associated herbivore
 community within an urban landscape. From the local habitat factors, leaf
 litter but not sunlight exposure was related to herbivore species
 richness, with leaf litter contributing to the maintenance of high species
 richness on isolated trees. Guilds and species differed strongly in their
 response to local habitat factors and connectivity, resulting in
 predictable variation in insect community composition among urban oaks.
 Taken together, our study shows an interactive effect of local and spatial
 factors on species richness and species composition within an urban
 context, with guild- and species-specific life histories determining the
 response of insects to urban landscapes. To maintain biodiversity in the
 urban landscape, preserving a dense network of local habitats is
 essential. Moreover, allowing leaf litter to accumulate can be a simple,
 cost-effective conservation management practice.

title: Botanical affinity of the taxa encountered in the Maywood Formation

description: This dataset lists the species of palynomorphs occurring in the Middle
 Devonian (Givetian) deposits of the Maywood Formation of Cottonwood
 Canyon, Wyoming, USA. The palynological investigation was carried out in
 order to decipher the age and paleoenvironment of the microconchid
 tubeworms (Tentaculita) which were described from the deposits of the
 Maywood Formation. The retrieved data suggest a likely brackish
 water origin for the deposits studied, although temporary fully freshwater
 conditions cannot be ruled out. Indeed, the terrestrial spores
 recovered from the Maywood samples belong to progymnosperm, lycopsid and
 primitive fern groups (see the data attached), which were major components
 of swamp plant communities, suggesting very close proximity of fresh water
 sources to the depositional paleoenvironment of the Maywood Formation. The
 highly abundant progymnosperm Geminospora spp., in particular,
 specifically suggests deposition in, or adjacent to, fluvio-lacustrine,
 lower floodplain, or paralic environments. Fine granular and fibrous
 amorphic organic matter with orange fluorescence has been linked with
 various terrestrial and algal aquatic sources. In addition, well-preserved
 terrestrial spores, and the presence of megaspores, tetrads, and pyrite,
 all support a brackish, shallow-water depositional setting. This is in
 agreement with other fossiliferous and lithologic evidence provided in
 this and in previous studies.
description: The palynomorphs were retrieved in order to better determine the
 age of the investigated deposits of the Maywood Formation and decipher
 their paleoenvironments. Four samples of organic rich shale, calcareous
 shale, and calcisiltite were subjected to standard palynologic maceration
 which was followed using HCl (10%) and HF (70%) and several washes with
 distilled water allowed the neutralization of residues, which were sieved
 using 5 µm meshes. Four slides mounts were made using a drop of residue
 mixed with one drop of polyvinyl alcohol. After drying, one drop of clear
 casting resin was added and the cover slip turned and sealed. The residues
 were oxidized with 3 ml of Schultz solution in a hot bath for a short
 time, and after washing and centrifuging until neutralization, a 10%
 solution of NH4OH was added. The residues were then placed in a hot water
 bath for two minutes, and washed three or four times. Two sets of slides
 were created: one set with oxidized residues and another set with oxidized
 residues stained with a drop of Bismarck Brown Y.

title: Disturbance and the (surprising?) role of ecosystem engineering in explaining spatial patterns of non-native plant establishment

description: The Intermediate Disturbance Hypothesis is widely considered to be wrong
 but is rarely tested against alternative hypotheses. It predicts that soil
 disturbances and herbivory have identical impacts on species richness via
 identical mechanisms (reduction in biomass and in competition). An
 alternative hypothesis is that the specific traits of disturbance agents
 (small mammals) and plants differentially affects richness or abundance of
 different plant groups. We tested these hypotheses on a degu (Octodon
 degus) colony in central Chile. We ask whether native and non-native forbs
 respond differently to degu bioturbation on runways vs. herbivory on
 grazing lawns. We ask whether this can explain the increase in non-native
 plants on degu colonies. We found that biopedturbation did not explain the
 locations of non-native plants. We did not find direct evidence of grazing
 increasing non-native herbs either, but a grazing effect appears to be
 mediated by grass, which is the dominant cover. Further, we provide
 supplementary evidence to support our interpretation that a key mechanism
 of non-native spread is the formation of dry soil conditions on grazing
 lawns. Thus ecosystem engineering (alteration of soil qualities) may be an
 outcome of disturbances, which each interact with specific plant traits,
 to create the observed pattern of non-native spread in the colony. Based
 on these results we propose to extend Jentsch & White’s (2019)
 concept of combined pulse/ disturbance events to the long-term process
 duality of ecosystem engineering/ disturbance.

title: From wild to cultivated varieties: The genetic variation and genomic domestication of Medicago polymorpha in China

description: Medicago polymorpha is a successful invasive plant and widespread around
 the world with its ability to adapt to the novel environment conditions
 quickly. However, the evolutionary dynamics after invasion still largely
 unclear so far. In this study, we performed a specific-length amplified
 fragments sequencing (SLAF-seq) of ten representative Medicago polymorpha
 accessions enrolled from different regions in China to infer the
 population structure and nucleotide diversity. As a result, total 52,237
 high-quality cross-species SNPs were identified. Population structure
 analysis based on these SNPs suggested entire Medicago polymorpha
 accessions could be divided into three groups, that is consistent with
 wild, intermediate, and cultivated. Moreover, a low level of gene flow
 occurred between cultivated and wild subgroups, and the wild subgroup had
 a higher allelic variation than the cultivated subgroup, which indicated
 that a genetic bottleneck may occurred during Medicago polymorpha
 domestication. The genotypic structure is no significant correlation with
 the geographic parameters (longitude and latitude) by Mantel test,
 suggested a rapid evolution to adapt to different environments.
 Additionally, selective sweep analyses found some improvement-selective
 genes. Gene function analysis revealed that they were primary involved in
 endonuclease activity and RNA-DNA hybrid ribonuclease activity biological
 processes, which are correlated with plant evolution. Therefore, we
 speculated these genes identified from selective sweep regions may have
 contributed to Medicago polymorpha domestication from wild to cultivated.
 Taken together, our results suggest that Medicago polymorpha has rapidly
 evolved across the invaded range. This will help us better understand the
 domestication history and intraspecific relationship of Medicago
 polymorpha, and provide basic information for breeding research in the
 future.

title: A common measure of prey immune function is not constrained by the cascading effects of predators

description: Simultaneously defending against predators, stymieing competitors, and
 generating immune responses can impose conflicting demands for host
 species caught in the entanglement of a food web. Host immunity is not
 only shaped by direct interactions among species, but also many indirect
 cascading effects. By reducing competition, predators in particular can
 affect resource acquisition necessary for hosts to mount energetically
 costly immune responses. However, identifying the links between predators
 and host immune responses determined by resource acquisition is a complex
 affair, because predators can (i) reduce host density and thus competition
 among hosts, (ii) exert non-consumptive trait-mediated effects on host
 resource acquisition behavior, and (iii) generate natural selection on
 host resource acquisition behavior. To examine the relative contributions
 of these potential predator driven density- and trait-mediated effects on
 a key aspect of immune function (total phenoloxidase activity, total PO),
 we conducted mesocosm and field experiments with larval damselflies (
 Enallagma signatum ) and their dominant fish predator ( Lepomis
 macrochirus ). Although we expected to observe declines in total PO
 activity with increases in damselfly density, we found no relationship
 between density and total PO activity. We also found no support for the
 prediction that total PO activity would vary as a result of either
 non-consumptive trait-mediated effects or selection on damselfly foraging
 activity underlying resource acquisition. Despite the lack of trait- or
 densitymediated effects, we did find that total PO activity increased with
 damselfly prey density among lakes, implying resource limitation for this
 aspect of immune function. These unexpected results point to the need to
 better understand the ecological conditions whereby predators and
 competitors constrain immune functions necessary for species to
 defend themselves in complex food webs.

title: Raw Data_The Dual-Path Association Between Upward Social Comparison and Short Video Addiction: Parallel Mediating Roles of Negative Emotions and Psychological Resilience

description: This dataset was collected through an online survey platform, Sojump (https://www.sojump.com/), from college students across various universities in China between November 2025 and January 2026. The primary goal of this research was to investigate the associations between upward social comparison, short video addiction, negative emotions, and psychological resilience. A total of 714 valid responses were obtained using a probability-based random sampling strategy to enhance sample representativeness.

 

The dataset includes demographic variables (such as gender, age, grade level) and psychological constructs related to social comparison, emotional responses, and resilience. The key variables examined include upward social comparison as the independent variable, short video addiction as the outcome variable, negative emotions and psychological resilience as mediators. The data were analyzed using partial least squares structural equation modeling (PLS-SEM). The findings aim to provide insights into the emotional and psychological processes underlying short video addiction, with a focus on the interplay of social comparison, emotional distress, and psychological resources.

 

This dataset is valuable for research in the fields of psychology, media studies, and behavioral addiction, particularly for studies aiming to understand the psychological dynamics associated with social media use and the potential for developing interventions targeting emotional resilience and healthy media consumption patterns.

title: Aldosterone and dexamethasone activate African lungfish mineralocorticoid receptor: Increased activation after removal of the amino-terminal domain

description: Aldosterone, the main physiological mineralocorticoid in humans and other
 terrestrial vertebrates, first appears in lungfish, which are lobe-finned
 fish that are forerunners of terrestrial
 vertebrates.  Aldosterone activation of the MR regulates
 internal homeostasis of water, sodium and potassium, which was critical in
 the conquest of land by vertebrates.  We studied
 transcriptional activation of the
 slender African lungfish MR by aldosterone,
 other corticosteroids and progesterone and find that aldosterone,
 11-deoxycorticosterone, 11-deoxycortisol and progesterone have
 half-maximal responses (EC50s) below 1 nM and are potential physiological
 mineralocorticoids.  In contrast, EC50s for
 corticosterone and cortisol were 23 nM and 66 nM,
 respectively.  Unexpectedly, truncated lungfish MR,
 consisting of the DNA-binding, hinge and steroid-binding domains, had a
 stronger response to corticosteroids and progesterone than full-length
 lungfish MR, indicating that the N-terminal domain represses steroid
 activation of lungfish MR, unlike human MR in which
 the N-terminal domain contains an activation
 function.  BLAST searches of GenBank did not retrieve a
 GR ortholog, leading us to test dexamethasone and triamcinolone for
 activation of lungfish MR.  At 10 nM, both synthetic
 glucocorticoids are about 4-fold stronger than 10 nM aldosterone in
 activating full-length lungfish MR, leading us to propose that lungfish MR
 also functions as a GR.
description: HEK cells were transfected with either lungfish MR or human MR.
  Then steroids were added and expression was measured 24 hours later.
  Data were processed on a computer and entered into a spreadsheet which
 could also show a graph of the data.
