title: Glacier Boundary and Ice Thickness Dataset (2023) for Southern Spitsbergen Derived Using the ICEBED Tool

description: This dataset provides glacier boundary and ice thickness information at 30 m spatial resolution for the year 2023, covering 242 glaciers located in southern Spitsbergen, Svalbard.Glacier boundaries were manually delineated for 2023 using pan-sharpened Landsat OLI imagery, employing multiple false-color composite combinations to enhance glacier identification. The outlines were further cross-validated using the Google Earth platform. The glacier inventory used for delineation is explicitly referenced, ensuring transparency and reproducibility. This approach ensures that the glacier boundaries are representative of conditions in 2023 and are contemporaneous with the elevation data used for ice-thickness estimation.Out of the 242 glaciers, ice thickness was estimated for 132 glaciers, for which suitable 2023 DEM coverage was available. Ice thickness estimation was performed using the ICEBED (ICe volumE and Bedtopography Estimation from DEM) tool, which implements the shear-stress-based GlabTop2_IITB model.The ice thickness dataset was generated using time-consistent inputs to minimize temporal mismatches between glacier outlines, elevation data, and the modeling framework—an issue that commonly affects earlier large-scale glacier thickness assessments. The ICEBED tool utilizes 2023 ArcticDEM Strip data at 30 m spatial resolution, together with glacier masks and surface slope, to derive spatially distributed ice thickness fields.Glacier-specific shape factors were computed following the established method of Ramsankaran et al. (2018), and the final ice thickness estimates were selected based on the closest match to the calculated glacier-specific shape factor.The resulting dataset provides spatially detailed glacier thickness and volume information for southern Spitsbergen in 2023. It is suitable for a wide range of applications, including glacier volume estimation, cryospheric change analysis, glaciological and hydrological modelling, sea-level rise assessment, and glacier-related hazard studies.

title: Data from: Genetic diversity and population structure of the Pelagic Thresher Shark (Alopias pelagicus) in the Pacific Ocean: evidence for two evolutionarily significant units

description: There has been an increasing concern about shark overexploitation in the
 last decade, especially for open ocean shark species, where there is a
 paucity of data about their life histories and population dynamics. Little
 is known regarding the population structure of the pelagic thresher shark,
 Alopias pelagicus. Though an earlier study using mtDNA control region
 data, showed evidence for differences between eastern and western Pacific
 populations, the study was hampered by low sample size and sparse
 geographic coverage, particularly a lack of samples from the central
 Pacific. Here, we present the population structure of Alopias pelagicus
 analyzing 351 samples from six different locations across the Pacific
 Ocean. Using data from mitochondrial DNA COI sequences and seven
 microsatellite loci we found evidence of strong population differentiation
 between western and eastern Pacific populations and evidence for
 reciprocally monophyly for organelle haplotypes and significant divergence
 of allele frequencies at nuclear loci, suggesting the existence of two
 Evolutionarily Significant Units (ESU) in the Pacific Ocean.
 Interestingly, the population in Hawaii appears to be composed of both
 ESUs in what seems to be clear sympatry with reproductive isolation. These
 results may indicate the existence of a new cryptic species in the Pacific
 Ocean. The presence of these distinct ESUs highlights the need for revised
 management plans for this highly exploited shark throughout its range.

title: Data from: Butterfly survival on an isolated island by improved grip

description: On small isolated islands, natural selection is expected to reduce the
 dispersal capacity of organisms, as short distances do not require a high
 rate of dispersal, which might lead to accidental emigration from the
 population. In addition, individuals foregoing the high cost of
 maintaining flight capacity may instead allocate resources to other
 functions. However, in butterflies and many other insects, flight is
 necessary not only for dispersal but also for most other activities. A
 weakly flying individual would probably do worse and have an elevated
 rather than reduced probability of accidental emigration. Here, we report
 results consistent with the hypothesis that a butterfly population on an
 isolated island, instead of having lost its flight capacity, has evolved
 better grip to resist the force of wind and to avoid being blown off the
 island. Our study suggests that local adaptation has occurred in this
 population in spite of its very small size (Ne ∼ 100), complete isolation,
 low genetic variation and high genetic load.

title: Data from: Lineages of Silene nutans developed rapid, strong, asymmetric postzygotic reproductive isolation in allopatry

description: Reproductive isolation can rise either as a consequence of genomic
 divergence in allopatry or as a byproduct of divergent selection in
 parapatry. To determine whether reproductive isolation in gynodioecious
 Silene nutans results from allopatric divergence or from ecological
 adaptation following secondary contact, we investigated the pattern of
 postzygotic reproductive isolation and hybridization in natural
 populations using two phylogeographic lineages, western (W1) and eastern
 (E1). Experimental crosses between the lineages identified strong,
 asymmetric postzygotic isolation between the W1 and the E1 lineages,
 independent of geographic overlap. The proportion of ovules fertilized,
 seeds aborted, and seeds germinated revealed relatively little effect on
 the fitness of hybrids. In contrast, hybrid mortality was high and
 asymmetric: while half of the hybrid seedlings with western lineage
 mothers died, nearly all hybrid seedlings with E1 mothers died. This
 asymmetric mortality mirrored the proportion of chlorotic seedlings, and
 is congruent with cytonuclear incompatibility. We found no evidence of
 hybridization between the lineages in regions of co-occurrence using
 nuclear and plastid markers. Together, our results are consistent with the
 hypothesis that strong postzygotic reproductive isolation involving
 cytonuclear incompatibilities arose in allopatry. We argue that the
 dynamics of cytonuclear gynodioecy could facilitate the evolution of
 reproductive isolation.

title: Data from: Resolving the roles of body size and species identity in driving functional diversity

description: Efforts to characterize food webs have generated two influential
 approaches that reduce the complexity of natural communities. The
 traditional approach groups individuals based on their species identity,
 while recently-developed approaches group individuals based on their body
 size. While each approach has provided important insights, they have
 largely been used in parallel in different systems. Consequently, it
 remains unclear how body size and species identity interact, hampering our
 ability to develop a more holistic framework that integrates both
 approaches. We address this conceptual gap by developing a framework which
 describes how both approaches are related to each other, revealing that
 both approaches share common but untested assumption about how variation
 across size classes or species influences differences in ecological
 interactions among consumers. Using freshwater mesocosms with dragonfly
 larvae as predators, we then experimentally demonstrate that while body
 size strongly determined how predators affected communities, these
 size-effects were species specific and frequently non-linear, violating a
 key assumption underlying both size- and species-based approaches.
 Consequently, neither purely species- nor size-based approaches were
 adequate to predict functional differences among predators. Instead,
 functional differences emerged from the synergistic effects of body size
 and species identity. This clearly demonstrates the need to integrate
 size- and species-based approaches to predict functional diversity within
 communities.

title: Data from: Selection mosaics differentiate Rhizobium–host plant interactions across different nitrogen environments

description: The nature and direction of coevolutionary interactions between species is
 expected to differentiate among distinct environments. Consequently,
 locally coevolved symbiotic traits would be well matched in similar
 environments, but mismatched elsewhere. In a classic mutualistic tradeoff,
 rhizobia provide nitrogen (N) to legume host plants in return for
 photosynthates. Despite earlier predictions, there is little evidence so
 far that spatial differences in soil N content mediate the coevolutionary
 outcome of the legume–Rhizobium mutualism. To test the existence of such
 selection mosaics, different genotypes of Vicia cracca and Rhizobium
 leguminosarum originating from spatially and environmentally highly
 differentiated sites were cross inoculated across different soil N
 regimes. In accordance with theoretical predictions, we found highly
 significant effects of genotype by genotype by environment (G× G × E)
 interactions, on both nodulation and plant growth, even when R.
 leguminosarum genotypes showed high genetic similarity. Our results show
 that the trajectory of the coevolutionary interactions between rhizobia
 and legumes is differentiated across different environments, and that
 selection mosaics may play an important role in shaping differences in the
 genetic composition of rhizobial populations.

title: Data from: Climate change surpasses land use change in the contracting range boundary of a winter-adapted mammal

description: The effects of climate change on biodiversity has emerged as a dominant
 theme in conservation biology, possibly eclipsing concern over habitat
 loss in recent years. The extent to which this shifting focus has tracked
 the most eminent threats to biodiversity is not well documented. We
 investigated the mechanisms driving shifts in the southern range boundary
 of a forest and snow cover specialist, the snowshoe hare, to explore how
 its range boundary has responded to shifting rates of climate and land
 cover change over time. We found that although forest and snow cover both
 contributed to the historical range boundary, current duration of snow
 cover best explains the most recent northward shift, while forest cover
 has declined in relative importance. In this respect, the southern range
 boundary of snowshoe hares has mirrored the focus of conservation
 research; first habitat loss and fragmentation was the stronger
 environmental constraint, but climate change has now become the main
 threat. Projections of future range show that climate change, and
 associated snow cover loss, will continue to be the major driver of this
 species’ range loss into the future.

title: Data from: Morphological, phylogenetic, and ecological diversity of the new model species Setaria viridis (Poaceae: Paniceae) and its close relatives

description: Premise of the study: Species limits of the emerging model organism
 Setaria viridis (tribe Paniceae, subtribe Cenchrinae) are not well
 defined. It is thought to be related to S. adhaerens, S. faberi, S.
 verticillata, and S. verticilliformis and in North America occurs with the
 morphologically similar S. pumila. An integrated approach was taken to
 evaluate its variation and relationships with the other taxa. Methods:
 Statistical morphology, flow cytometry, molecular phylogenetics, and
 growth experiments were employed to examine the group’s physical
 variation, polyploidy, evolutionary relationships, and drought ecology,
 respectively. Key results: Setaria viridis contributed one genome to the
 tetraploids S. faberi, S. verticillata, and S. verticilliformis; the other
 genome of the latter two was contributed by S. adhaerens. Setaria pumila
 is unrelated. Morphologically, S. viridis is most similar to S. faberi,
 but all tested accessions of S. viridis were diploid, whereas those of S.
 faberi were all tetraploid. Principal component analysis of 70
 morphological characters consistently separated S. viridis from S. faberi,
 largely by spikelet characters. The diagnostic morphological characters
 are not affected by watering. Setaria faberi is far more sensitive to
 drought, in terms of mortality and morphological stunting, than S. viridis
 or S. pumila. Conclusions: Setaria viridis is a diploid species and has
 contributed to several polyploid derivatives. The most morphologically
 similar of the polyploids is S. faberi, which differs in spikelet
 features, phylogenetics, genome size, and ecological response to drought.
 Researchers using field-collected S. viridis as a model organism will
 benefit from the clear delimitation provided in this study.

title: Data from: Shorter juvenile telomere length is associated with higher survival to spawning in migratory Atlantic salmon

description: The risk of mortality associated with a long-distance migration will
 depend on an animal's physiological state, as well as the prevailing
 ecological conditions. Here we assess whether juvenile telomere length,
 which in endotherms has been shown to be a biomarker of physiological
 state and expected lifespan, predicts whether wild Atlantic salmon Salmo
 salar successfully complete their marine migration. Over 1800 juvenile
 fish were trapped, measured, PIT-tagged and a tissue biopsy taken when
 migrating as juveniles down-river towards the sea. Survivors of the marine
 phase of the life cycle were then re-trapped and re-sampled when returning
 to the river to spawn as sexually mature adults, 1.5-2.5 years later. Most
 individuals experienced a reduction in telomere length during the marine
 migratory phase of their life cycle. While the relative rate of telomere
 loss was greater in males than females, telomere loss was unrelated to
 growth at sea. Contrary to expectations, salmon that had the shortest
 telomeres at the time of the outward migration had the greatest
 probability of surviving through to the return migration. This effect,
 independent of body size, may indicate a trade-off between investment in
 readiness for marine life (which favours high glucocorticoid levels, known
 to increase telomere attrition in other vertebrate species) and investment
 in telomere maintenance. Survival was also significantly influenced by the
 seasonal timing of outward migration, with the fish migrating downstream
 earliest in the spring having the highest probability of return. This
 study reveals that telomere length is associated with survival, although
 in ways that contrast with patterns seen in endotherms. This illustrates
 that while telomeres may be universally important for chromosome
 protection, the potential for telomere dynamics to predict performance may
 vary across taxa.

title: Data from: Two-phase increase in the maximum size of life over 3.5 billion years reflects biological innovation and environmental opportunity

description: NOTE: See also http://bodysize.nescent.org. ABSTRACT: The maximum size of
 organisms has increased enormously since the initial appearance of life
 &gt;3.5 billion years ago (Gya), but the pattern and timing of this
 size increase is poorly known. Consequently, controls underlying the size
 spectrum of the global biota have been difficult to evaluate. Our
 period-level compilation of the largest known fossil organisms
 demonstrates that maximum size increased by 16 orders of magnitude since
 life first appeared in the fossil record. The great majority of the
 increase is accounted for by 2 discrete steps of approximately equal
 magnitude: the first in the middle of the Paleoproterozoic Era (≈1.9 Gya)
 and the second during the late Neoproterozoic and early Paleozoic eras
 (0.6–0.45 Gya). Each size step required a major innovation in organismal
 complexity—first the eukaryotic cell and later eukaryotic
 multicellularity. These size steps coincide with, or slightly postdate,
 increases in the concentration of atmospheric oxygen, suggesting latent
 evolutionary potential was realized soon after environmental limitations
 were removed.
