Data for: Implications of plant N/P stoichiometry influenced by arbuscular mycorrhizal fungi for stability of plant species and community in response to nutrient limitation
<p>Arbuscular mycorrhizal fungi (AMF) influence plant nitrogen/phosphorus (N/P) by modifying plant N and P uptake, which further affects plant stoichiometric N/P homeostasis. Plant species and community stoichiometric N/P homeostasis can impact plant species and community stability, respectively, in response to variations of soil N and P availabilities. We investigated interspecific plant interactions via AMF in regard to plant and soil microbial N/P stoichiometry across different soil N and P availabilities induced by N and P addition (0 mg N kg<sup>-1</sup>, 25 mg N kg<sup>-1</sup>, 50 mg N kg<sup>-1</sup>, 30 mg P kg<sup>-1</sup>, and 100 mg P kg<sup>-1</sup>). We selected one dominant (<em>Bothriochloa ischaemum</em>; C4 grass) and one subordinate (<em>Lespedeza davurica</em>; legume) species in a natural grassland climax community. We examined how AMF influences stoichiometric N/P homeostasis in monoculture and mixed culture systems, and the resulting consequences for temporal stability of plant species and community in response to variations in soil N and P availability.</p> <p>The AMF mitigated the P limitation of soil microbial communities and decreased the degree of stoichiometric N/P homeostasis of host plants in monoculture. Through their resource-scavenging and soil organic matter mineralisation functions, AMF enhances plant 'luxury consumption', promoting species stability in monoculture in response to soil N and P availability variations. Compared with plants in monoculture, the interaction between <em>B. ischaemum</em> and <em>L. davurica</em> via AMF increased shoot N/P under soil N-poor conditions, leading to an enhanced degree of stoichiometric N/P homeostasis in both plant species, especially the legume.</p> <p>Our results suggest that interspecific plant interaction between C4 grass and legume mediated by AMF confers an advantage in complementarity in plant N acquisition under N-poor conditions, leading to increased stability of plant communities and better maintenance of subordinate species (legume) in response to soil N deficiency.</p>

Data: Upper thermal limits and risk of mortality of coastal Antarctic ectotherms
<p><span>Antarctic marine animals face one of the most extreme thermal environments, characterized by a stable and narrow range of low seawater temperatures. At the same time, the Antarctic marine ecosystems are threatened by accelerated global warming. Determining the upper thermal limits (CTmax) is crucial to project the persistence and distribution areas of the Antarctic marine species. Using thermal death time curves (TDT), we estimated CTmax at different temporal scales from 1 minute to daily and seasonal, the predict vulnerability to the current thermal variation and two potential heatwave scenarios. Our results revealed that CTmax at 1 min are far from the temperature present in the marine intertidal area where our study species, showing Echinoderm species higher CTmax than the Chordata and Arthropods species. Simulations indicated that seasonal thermal variation from the intertidal zone contributed to basal mortality, which increased after considering moderate scenarios of heatwaves (+2 °C) in the Shetland Archipelago intertidal zone. Our finding highlighted the relevance of including exposure time explicitly on the CTmax estimates, which deliver closer and more realistic parameters according to the species that may be experiencing in the field.</span></p>

Data for: Tensile cracks can shatter classical speed limits

At</span> <span>their tips, tensile cracks dissipate elastic energy </span><span>stored in the surrounding material to create newly</span> <span>fractured surfaces, precisely maintaining `energy </span><span>balance' by exactly equating the energy flux with</span> <span>dissipation.

Data for taxon-dependent effects of dispersal limitation versus environmental filters on bryophyte assemblages―Multiple perspective studies in land-bridge islands
<p><strong><span>Aim</span></strong><span>: To explore the taxon-dependent contribution of dispersal limitation vs. environmental filters to bryophyte assemblages.</span></p> <p><strong><span>Location</span></strong><span>: The Thousand Island Lake, China </span></p> <p><strong><span>Taxon</span></strong><span>: Bryophytes</span></p> <p><strong><span>Methods</span></strong><span>: We compared the observed beta diversity with the expected values based on six null models (EE, EF, FE, FF, PE, PF) and detected the partial correlation of beta diversity with geographical distances. We quantified the contributions of spatial vs. environmental variables, and island isolation per se to species composition (SC) by using variance partitioning. We modeled the species-area relationships (SARs) for bryophytes and other eight biotas. To explore the taxon-dependent effects of spatial vs. environmental filters on bryophytes, sixteen taxa including five categories (total bryophytes, total mosses, liverworts, acrocarpous and pleurocarpous mosses) and eleven species-richest families were included in the analyses.</span></p> <p><strong><span>Results</span></strong><span>: The observed beta diversity values were significantly different from the predicted values based on the six null models for all 16 taxa. For all five categories, the observed partial correlations between beta diversity and geographical distance after controlling environmental effects were not only positive but also significantly different from the predicted values based on the null models. Spatial eigenvectors are more important in shaping SC than environmental variables for all 16 taxa except Brachytheciaceae and Anomodontaceae. Spatial eigenvectors contributed more to SC variation in liverworts than in mosses, and in pleurocarpous mosses than in acrocarpous mosses. The effects of island isolation on SC were significant for all five categories and varied </span><span>highly </span><span>at the family level. The z-values of the SARs for the five bryophyte categories were all larger than those of the other eight biotas.</span></p> <p><span><strong>Main</strong> <strong>conclusions</strong></span><span>: In subtropical fragmented forests, dispersal limitation exerted significant, taxon-dependent effects on bryophyte assemblages. It was dispersal limitation rather than environmental filtering that predominantly regulated SC patterns of bryophytes. </span></p>
Supporting data for: Whole genome sequencing reveals fine-scale environment associated divergence near the range limits of a temperate reef fish
<p>Environmental variation is increasingly recognized as an important driver of diversity in marine species despite the lack of physical barriers to dispersal and the presence of pelagic stages in many taxa. A robust understanding of the genomic and ecological processes involved in structuring populations is lacking for most marine species, often hindering management and conservation action. Cunner (<em>Tautogolabrus adspersus</em>), is a temperate reef fish with both pelagic early life history stages and strong site-associated homing as adults; the species is also of interest for use as a cleaner fish in salmonid aquaculture in Atlantic Canada. We aimed to characterize genomic and geographic differentiation of cunner in the Northwest Atlantic. To achieve this, a chromosome-level genome assembly for cunner was produced and used to characterize spatial population structure throughout Atlantic Canada using whole genome resequencing. The genome assembly spanned 0.72 Gbp and 24 chromosomes; whole genome resequencing of 803 individuals from 20 locations from Newfoundland to New Jersey identified approximately 11 million genetic variants. Principal component analysis revealed four regional Atlantic Canadian groups. Pairwise F<sub>ST</sub> and selection scans revealed signals of differentiation and selection at discrete genomic regions, including adjacent peaks on chromosome 10 across multiple pairwise comparisons (<em>i.e.</em>, F<sub>ST</sub> 0.5–0.75). Redundancy analysis suggested association of environmental variables related to benthic temperature and oxygen range with genomic structure. Results suggest regional scale diversity in this temperate reef fish and can directly inform the collection and translocation of cunner for aquaculture applications and the conservation of wild populations throughout the Northwest Atlantic.</p>
Data for: Multi-scale relationships in thermal limits within and between two cold-water frog species uncover different trends in physiological vulnerability
<ol> <li>Critical thermal limits represent an important component of an organism's capacity to cope with future temperature changes. Understanding the drivers of variation in these traits may uncover patterns in physiological vulnerability to climate change. Local temperature extremes have emerged as a major driver of thermal limits, although their effects can be mediated by the exploitation of fine-scale spatial variation in temperature through behavioral thermoregulation.</li> <li>Here, we investigated thermal limits along elevation gradients within and between two cold-water frog species (<em>Ascaphus</em> spp.), one with a coastal distribution (<em>A. truei</em>) and the other with a continental range (<em>A. montanus</em>). We quantified thermal limits for over 700 tadpoles, representing multiple populations from each species. We combined local temporal and fine-scale spatial temperature data to quantify local thermal landscapes (i.e., thermalscapes), including the opportunity for behavioral thermoregulation.</li> <li>Lower thermal limits for either species could not be reached experimentally reached without the water freezing, suggesting that cold tolerance is <0.3℃. In contrast, upper thermal limits varied among populations, but this variation only reflected local temperature extremes in <em>A. montanus</em>, perhaps due to greater variation in stream temperatures across its range. Lastly, we found minimal fine-scale spatial variability in temperature, suggesting limited opportunity for behavioral thermoregulation and thus increased vulnerability to warming for all populations.</li> <li>By quantifying local thermalscapes, we uncovered different trends in the relative vulnerability of populations across elevation for each species. In <em>A. truei</em>, physiological vulnerability decreased with elevation, whereas in <em>A. montanus</em>, all populations were equally physiologically vulnerable. These results highlight how similar environments can differentially shape physiological tolerance and patterns of vulnerability of species, and in turn, impact their vulnerability to future warming. </li> </ol>
