The stress- and fluid-pressure-driven frictional slip data for variably roughened fractures in Gonghe granite
<p class="Abstract"><a name="_Hlk122089471"></a><span>We explore</span><span> the impacts of stress- and fluid-pressure-driven frictional slip on variably roughened fractures in Gonghe granite (Qinghai province, China). Slip is on an inclined fracture under simple triaxial stresses with concurrent fluid throughflow allowing fault permeability to be measured both pre- and post-reactivation. Under stress-drive, smooth faults are first slip-weakening and transition to slip-strengthening with rough faults slip-strengthening, alone. A friction criterion accommodating a change in friction coefficient and fault angle is able to fit the data of stable-slip and stick-slip. Under fluid-pressure-drive, excess pore pressures must be significantly larger than average pore pressures suggested by the stress-drive-derived failure criterion. This overpressure is conditioned by the heterogeneity of the pore pressure distribution in radial flow on the fault and related to the change in permeability</span><span>. Fault roughness impacts both the coefficient of friction and the permeability and therefore exerts important controls in fluid-injection-induced earthquakes.</span><span> </span><span>The results potentially improve our ability to assess and mitigate the risk of injection-induced earthquakes in EGS.</span><span> </span></p>

Data from: Biotic pressures and environmental heterogeneity shape beta-diversity of seedling communities in tropical montane forests
<p>Many theories have been proposed to explain the high diversity of plants in the tropics. However, we lack an understanding of the processes that drive plant diversity and community assembly at different spatial scales. Here, we applied beta-diversity partitioning to test how biotic and abiotic factors are associated with seedling beta-diversity in a tropical montane forest in Southern Ecuador. We recorded seedling communities on 81 subplots at nine plots located at three elevations along a 2000-m elevational gradient. We measured biotic pressures (i.e. herbivory and fungal pathogen attacks) and environmental conditions (i.e. soil moisture and canopy closure) at all subplots and related them to species turnover and richness differences in seedling communities within and between elevations. We found that species turnover increased with differences in biotic dissimilarity within elevations, while differences in species richness within elevations increased with increasing environmental dissimilarity. Between elevations, species turnover increased with increasing environmental dissimilarity. Our findings show that species turnover and changes in species richness are related differently to abiotic and biotic factors, and that the importance of these factors for shaping seedling diversity is scale-dependent. Our study contributes to better understand the processes driving seedling beta-diversity and the assembly of plant communities in highly diverse tropical montane forests.</p>

Data from: Direct evidence of permeability evolution of Nanan granite after two cooling paths under different confining pressures: A comparative study
<p>Permeability decides the mass transfer behavior and plays a key role in the heat extraction of enhanced geothermal systems (EGSs), and the aim of the injection of cooling water is to enhance permeability within the geothermal reservoirs. Direct evidence of how cool water affecting permeability evolution is still limited. Therefore, we explored the permeability evolution of Nanan granite after air and water cooling under different confining pressures combined with optical microscopy and X-ray CT observation. We found that there are lots of microdefects observed in Nanan granite after two cooling paths, which dominantly drives the evolution of permeability from a microscopic scale. The permeabilities of granite under water-cooling condition are always larger than those under air-cooling condition, and water-cooling treatment further enhances the permeability of specimens. The permeabilities of granite specimens after two cooling paths decrease with confining stress. More microcracks and better connectivity among microcracks produce a larger permeability within the specimen after water cooling. The observed microcracks are regarded as the seepage channels and direct microscale evidence of permeability evolution of granite after two cooling paths. Our results may suggest that water injection is an efficient way for permeability enhancement due to thermal microcracks propagation in thermal simulation.</p>

Combined P-V-T Data for hcp-Fe with Reevaluated Pressures and Pressure Uncertainties
<p>This dataset consists of unit-cell volumes, temperatures, and reevaluated pressures, and their related uncertainties for <em>hcp-</em>Fe. The volumes and temperatures are taken from previous studies (indicated under the column "Original Publication"), and the pressures were reevaluated using the internally consistent pressure scales of Fei <em>et al</em>., 2007. The pressure uncertainties presented here propagate uncertainties in the volume and temperature measurements, as well as the uncertainty and covariance in the equation of state parameters used to determine the pressure. Also listed are the beamline the data were originally collected at, and the compression technique (DAC= Diamond Anvil Cell; MAP= Multi-Anvil Press).</p>

Data from: breeding under pressure: corticosterone is associated with reproductive investment under fluctuating predation risk in a long-lived sea duck
<p>Phenotypic plasticity may enable individuals to cope with predictable and unpredictable environments during their life-cycle. In that context, studying glucocorticoids – corticosterone (CORT) in birds – is relevant because of their primary role in allostasis. Higher baseline CORT levels are classically associated with environmental constraints and lower fitness (the CORT-fitness hypothesis). However, in some environments, higher baseline CORT levels can promote reproduction, therefore being associated with higher fitness (the CORT-adaptation hypothesis). These two hypotheses have been tested in multiple systems, but rarely in a context of fluctuating predation threat.</p> <p>We <span>used a </span>long-term individual-based monitoring of baseline CORT levels in female common eiders <em>Somateria mollissima</em> (n<sub>CORT</sub> = 1537; n<sub>individual</sub> = 790; 2009-2022) to disentangle the context-dependent links between environmental conditions, CORT and fitness. Importantly, the study population has been facing a drastic increase in predation pressure over the past decades, linked to the recovery of the white-tailed eagle <em>Haliaeetus albicilla</em>. Additionally, eiders breed on open or forested islands, further affecting adult and nest predation risk. This system allowed us to disentangle the relative contributions of within- and among-individual variation in baseline CORT levels under predation.</p> <p>Supporting the CORT-adaptation hypothesis, baseline CORT levels were positively associated with reproductive investment (clutch size), age and hatching success. By partitioning within- and among-individual effects, we showed that at the individual level, CORT flexibly increased with clutch size and age. Females displaying higher CORT levels were more successful, suggesting a link between CORT and individual quality.</p> <p><span>At both the population and individual levels, baseline CORT levels decreased over the study period. This decrease was correlated with an increase in predation risk. Females had reduced baseline CORT when nesting under high eagle abundance or adult predation risk (within-individual effect). Interestingly, apparent plasticity towards adult predation risk was only observed on open islands, likely reflecting habitat-dependent strategies.</span></p> <p><span>Consistent with the CORT-adaptation hypothesis, we show that changes in predation regime not only correlate with changes in reproductive investment, but also with rapid plastic adjustment of glucocorticoid levels and therefore individual strategies to cope with predation risk. Given the correlative nature of our study, we encourage further experimental studies testing for a causal relationship between predation and corticosterone levels.</span></p>
