title: Data from: Upward elevation and northwest range shifts for alpine Meconopsis species in the Himalaya-Hengduan Mountains region

description: Climate change may impact the distribution of species by shifting their
 ranges to higher elevations or higher latitudes. The impacts on alpine
 plant species may be particularly profound due to a potential lack of
 availability of future suitable habitat. To identify how alpine species
 have responded to climate change during the past century as well as to
 predict how they may react to possible global climate change scenarios in
 the future, we investigate the climatic responses of seven species of
 Meconopsis, a representative genus endemic in the alpine meadow and
 subnival region of the Himalaya–Hengduan Mountains. We analyzed past
 elevational shifts, as well as projected shifts in longitude, latitude,
 elevation, and range size using historical specimen records and species
 distribution modeling under optimistic (RCP 4.5) and pessimistic (RCP 8.5)
 scenarios across three general circulation models for 2070. Our results
 indicate that across all seven species, there has been an upward shift in
 mean elevation of 302.3 m between the pre‐1970s (1922–1969) and the
 post‐1970s (1970–2016). The model predictions suggest that the future
 suitable climate space will continue to shift upwards in elevation (as
 well as northwards and westwards) by 2070. While for most of the analyzed
 species, the area of suitable climate space is predicted to expand under
 the optimistic emission scenario, the area contracts, or, at best, shows
 little change under the pessimistic scenario. Species such as M. punicea,
 which already occupy high latitudes, are consistently predicted to
 experience a contraction of suitable climate space across all the models
 by 2070 and may consequently deserve particular attention by conservation
 strategies. Collectively, our results suggest that the alpine
 high‐latitude species analyzed here have already been significantly
 impacted by climate change and that these trends may continue over the
 coming decades.

title: Data from: Adapting in larger numbers can increase the vulnerability of Escherichia coli populations to environmental changes

description: Larger populations generally adapt faster to their existing environment.
 However, it is unknown if the population size experienced during evolution
 influences the ability to face sudden environmental changes. To
 investigate this issue, we subjected replicate Escherichia coli
 populations of different sizes to experimental evolution in an environment
 containing a cocktail of three antibiotics. In this environment, the
 ability to actively efflux molecules outside the cell is expected to be a
 major fitness-affecting trait. We found that all the populations
 eventually reached similar fitness in the antibiotic cocktail despite
 adapting at different speeds, with the larger populations adapting faster.
 Surprisingly, whereas efflux activity enhanced in the smaller populations,
 it decayed in the larger ones. The evolution of efflux activity was
 largely shaped by pleiotropic responses to selection and not by drift.
 This demonstrates that quantitative differences in population size can
 lead to qualitative differences (decay/enhancement) in the fate of a
 character during adaptation to identical environments. Furthermore, the
 larger populations showed inferior fitness upon sudden exposure to several
 alternative stressful environments. These observations provide a novel
 link between population size and vulnerability to environmental changes.
 Counter-intuitively, adapting in larger numbers can render bacterial
 populations more vulnerable to abrupt environmental changes.

title: Data from: Seed dispersal and fine-scale genetic structuring in the asexual Nigritella miniata (Orchidaceae) in the Alps

description: Orchids have minute, air-filled seeds and are considered as efficient
 dispersers and colonizers. Yet, empirical studies show that most seeds
 fall within the nearest metre from the mother plant in orchids, and that
 individuals standing close to each other are often closely related. A poor
 contribution to gene dispersal by seeds may be compensated for by more
 efficient dispersal by pollen, but in autogamous or agamospermous orchids
 this component is not available. Here, we used two highly variable simple
 sequence repeat loci to analyze fine-scale genetic structure in the
 agamospermous orchid Nigritella miniata, which is widespread in alpine
 grasslands in the Dolomites. We studied a densely populated area of 30×50
 m and an enlarged area of 100×500 m with more scattered occurences. Sp
 statistics, describing the decrease in relatedness with geographic
 distance, were 0.1073 and 0.0609, respectively, and were among the highest
 values recorded for the orchid family, revealing a strong genetic
 structuring. Still, some of the genotypes in the studied area were
 distributed at distances up to 26.5 km in the Dolomites, which suggests
 that long-distance seed dispersal occurs occasionally and that populations
 separated by long distances can still be parts of the same metapopulation
 system.

title: Data from: With Ellenberg indicator values towards the north: does the indicative power decrease with distance from Central Europe?

description: Aim: Ellenberg indicator values (EIV) are frequently used in regions
 outside their Central European origin as proxies for environmental
 conditions, a practice further boosted by the increasing scientific focus
 on global change. The performance of EIV outside their geographic origin
 and over long gradients has, however, rarely been tested. The aim of this
 study was to evaluate if the indicative power of EIV changes over a large
 geographic gradient and to analyze the potential causes of such changes.
 Location: Sweden Taxon: Vascular plants Methods: We used data on forest
 understory vegetation and soils from &gt;15 000 plots from the Swedish
 National Forest Inventory to model how the relationship between community
 mean EIV and measured environmental variables changes along an extensive
 latitudinal gradient (&gt;15°). We used Generalized Additive Mixed
 Models to account for the inventory design, and for potential
 non-linearities in the relationship between the mean EIV and the
 environmental variables. Additionally, HOF models were developed for the
 relationship between the incidence probability and the environmental
 variables to analyze if the widths of species niches change along the
 geographic gradient. Results: Our study shows that EIV for N (nutrients),
 R (pH) and T (temperature) are useful as far north as the Arctic Circle,
 while those for K (continentality) showed a much weaker relationship with
 measured continentality. However, the indicative power of the EIV for N
 and R gradually became weaker towards the north along with shifts towards
 larger environmental niche widths of the indicator species. Main
 conclusions: EIV are useful indicators of soil conditions in boreal
 forests located far north of Central Europe. However, the drop in
 indicative power in the northernmost regions due to increasing
 environmental niche widths needs to be taken into account when applying
 EIV along long geographic gradients to avoid spatial bias.

title: Data from: Desiccation and rehydration of mosses greatly increases resource fluxes that alter soil carbon and nitrogen cycling

description: 1. Mosses often have positive effects on soil carbon and nitrogen cycling,
 but we know little about how environmentally determined cycles of
 desiccation and rehydration in mosses influence these processes. 2. In
 this context, we compared carbon and nitrogen in throughfall after
 precipitation passed through eight moss species that were either hydrated
 continuously or desiccated and rehydrated. Also, the throughfall of four
 moss species was added to soil and used to determine the net effect of
 carbon and nitrogen added in moss throughfall on soil CO2 and N2O efflux.
 3. Depending on the species, desiccated-rehydrated (rehydrated) mosses
 lost 2-31 times more carbon in throughfall than mosses that were
 continuously hydrated (hydrated). Hydrated mosses lost little to no
 detectable nitrogen; whereas most rehydrated mosses lost some nitrogen in
 throughfall. Throughfall from both hydrated and rehydrated mosses
 generated higher CO2 and N2O efflux than water treated soils, but
 rehydrated moss throughfall promoted larger N2O efflux than hydrated moss
 throughfall. Throughfall from hydrated mosses caused net negative changes
 in soil carbon and had very little effect on soil nitrogen, whereas
 throughfall from rehydrated mosses generated positive changes in soil
 carbon and nitrogen. 4. Synthesis. Our results indicate that resources
 lost from desiccated mosses during rehydration influence soil carbon and
 nitrogen transformations and may be important drivers of carbon and
 nitrogen cycling and storage in ecosystems.

title: Data from: A new ophiocistioid with soft-tissue preservation from the Silurian Herefordshire Lagerstätte, and the evolution of the holothurian body plan

description: Reconstructing the evolutionary assembly of animal body plans is
 challenging when there are large morphological gaps between extant sister
 taxa, as in the case of echinozoans (echinoids and holothurians). However,
 the inclusion of extinct taxa can help bridge these gaps. Here we describe
 a new species of echinozoan, Sollasina cthulhu, from the Silurian
 Herefordshire Lagerstätte, UK. S. cthulhu belongs to the ophiocistioids,
 an extinct group that shares characters with both echinoids and
 holothurians. Using physical-optical tomography and computer
 reconstruction, we visualize the internal anatomy of S. cthulhu in three
 dimensions, revealing inner soft tissues that we interpret as the ring
 canal, a key part of the water vascular system that was previously unknown
 in fossil echinozoans. Phylogenetic analyses strongly suggest that
 Sollasina and other ophiocistioids represent a paraphyletic group of stem
 holothurians, as previously hypothesized. This allows us to reconstruct
 the stepwise reduction of the skeleton during the assembly of the
 holothurian body plan, which may have been controlled by changes in the
 expression of biomineralization genes.

title: Data from: Isolation, marine transgression, and translocation of the bare-nosed wombat (Vombatus ursinus)

description: Island populations can represent genetically distinct and evolutionarily
 important lineages relative to mainland conspecifics. However, phenotypic
 divergence of island populations does not necessarily reflect genetic
 divergence, particularly for lineages inhabiting islands periodically
 connected during Pleistocene low sea stands. Marine barriers may also not
 be solely responsible for any divergence that is observed. Here, we
 investigated genetic divergence among and within the three
 phenotypically-distinct subspecies of bare-nosed wombats (Vombatus
 ursinus) in southeast Australia that are presently—but were not
 historically—isolated by marine barriers. Using genome-wide single
 nucleotide polymorphisms we identified three genetically distinct groups
 (mainland Australia, Bass Strait island, Tasmania) corresponding to the
 recognised subspecies. However, isolation by distance was observed in the
 Tasmanian population, indicating additional constraints on gene flow can
 contribute to divergence in the absence of marine barriers, and may also
 explain genetic structuring among fragmented mainland populations. We
 additionally confirm origins and quantify the genetic divergence of an
 island population 46 years after the introduction of 21 individuals from
 the Vulnerable Bass Strait subspecies. In light of our findings we make
 recommendations for the maintenance of genetic variation and fitness
 across the species range.

title: Study Dataset: Advertisements and Recommendations of Apple's and Google's EU App Stores

description: This is the study dataset from the paper "Ad Personalization and Transparency in Mobile Ecosystems: A Comparative Analysis of Google’s and Apple’s EU App Stores" by David Breuer, Lucas Becker, and Matthias Hollick in Proceedings on Privacy Enhancing Technologies 2026 (Issue 1).

 

Paper Abstract:

Smartphones have become the primary interface to the Internet for many users, making app stores an essential part of the mobile ecosystem. Apple's App Store and Google's Play Store form a duopoly of the two largest app stores, both of which offer targeted advertisements in their store ecosystems. Consequently, their need for user data to improve the targeting of ads conflicts with users' desire for privacy. Users have to trust the statements given in privacy policies that are often scattered over multiple places and they have no way of overseeing how their data is used for ad targeting. The European Union passed several regulations, most notably the DSA and DMA, addressing this transparency issue. The implementation of these laws, however, must be audited to ensure their effectiveness. Unfortunately, the transparency measures implemented in the context of advertising and the ad-targeting mechanisms in app stores have received little attention so far. In this work, we analyze the first-party ad tracking ecosystem on Apple's and Google's app stores. We measure the effects of different account parameters and interest patterns on the ads these accounts receive. Furthermore, we study the transparency measures implemented by the platforms. While we only detect rare occurrences of targeted advertising, we find Google's recommendations to be highly personalized. We notice multiple issues with the realization of transparency measures that affect their effectiveness and, in our opinion, contradict corresponding EU laws.

title: Data from: Grassland plants show no relationship between leaf drought tolerance and soil moisture affinity, but rapidly adjust to changes in soil moisture

description: 1. Assessing drought tolerance and the ability of plants to adjust to
 changes in available water resources is crucial for understanding current
 and future distributions of plant species. While turgor loss point (πtlp)
 has been recognized as a direct determinant of drought tolerance in woody
 plants, information on it for grassland species is largely missing. 2. We
 first validated a rapid method to estimate πtlp for grassland species,
 using osmometry measurements (πtlp-osm) of osmotic potential at full
 hydration (πo-osm), originally proposed for woody species. We confirmed
 that πo-osm was tightly positively related to πtlp measured by the classic
 pressure–volume curve (πtlp-pv). Cell wall elasticity was not important in
 the maintenance of turgor and neither specific leaf area nor leaf dry
 matter content influenced πtlp. 3. We then studied the relationship
 between πtlp-osm measured under controlled conditions and species’ soil
 moisture affinity (Ellenberg indicator values) in 40 diverse grassland
 species from the full range of soil moisture conditions found in temperate
 grasslands. On a subset of 12 species, we studied the adjustment in
 πtlp-osm to drought stress and recovery from drought. 4. We hypothesized
 that dry grassland species are better adapted to drier conditions by
 having comparatively higher leaf drought tolerance (more negative πtlp)
 and a better ability to adjust to acute drought stress. 5. We found that
 πtlp-osm was unrelated to species’ soil moisture affinity. However, all
 species developed higher leaf drought tolerance by decreasing πtlp-osm
 after seven weeks of drought stress. After only one week of recovery, all
 species reduced the leaf drought tolerance back to the πtlp-osm level
 comparable with non-stressed plants. 6. Our results considerably extend
 the relationship between πo-osm and πtlp, originally defined for woody
 species, and thus propose a yet unexploited direct method for assessing
 leaf drought tolerance via turgor loss point in herbaceous species.
 However, the lack of relationship between πtlp and soil moisture affinity
 suggests that, unlike in woody plants, leaf-level drought tolerance in
 grassland plants does not fully translate into whole-plant drought
 resistance, suggesting an importance of other drought resistance
 strategies.
