The topology of spatial networks affects stability in experimental metacommunities
<p><span>Understanding the drivers of community stability has been a central goal in ecology. Traditionally the emphasis has been placed on studying the effects of biotic interactions on community variability, and less is understood about how the spatial configuration of habitats promotes or hinders metacommunity stability. To test the effects of contrasting spatial configurations on metacommunity stability, I designed metacommunities with patches connected as random or scale-free networks. In these microcosms, two prey and one protist predator dispersed, and I evaluated community persistence, tracked biomass variations, and measured synchrony between local communities and their neighbors. After 30 generations, scale-free metacommunities had lower global biomass variability and higher persistence, suggesting higher stability. At the local scale, patches in scale-free metacommunities showed a positive relationship between variability and patch connectivity, indicating higher stability in isolated communities. No clear relationship was observed in random networks. These results suggest the increased heterogeneity in connectivity of scale-free networks favors the prevalence of isolated patches in the metacommunity, which likely act as refugia against competition—the most dominant interaction in this system—resulting in higher global stability. These results highlight the importance of accounting for network topology in the study of spatial dynamics.</span></p>

Stability of algebraic spin liquids coupled to quantum phonons
<p>Algebraic spin liquids are quantum disordered phases of insulating magnets which exhibit fractionalized gapless excitations and power-law correlations. Quantum spin liquids in this category include the experimentally established 1D Luttinger liquid, as well as the U(1) Dirac spin liquid (DSL) which has been a focus of recent candidate materials searches. Most notably, several exchange-frustrated Heisenberg materials on the triangular lattice have shown evidence of the U(1) DSL. In this work, we measure the algebraic correlations of spin-singlet excitations in the $J_1$–$J_2$ antiferromagnetic Heisenberg model on the triangular lattice, prompting a detailed investigation of this model's stability under spin-phonon coupling using variational Monte Carlo. As seen before in 1D spin chains, we observe a low-temperature transition from a U(1) DSL to valence bond order and predict the parameter regime where the model realizes a stable DSL ground state. To achieve this, we employ a series of finite-size scaling Ansätze inspired by the low-energy DSL's conformal description in terms of quantum electrodynamics, and show that emergent monopole operators drive the instability. We compare the physics of this transition to the 1D Luttinger liquid throughout our analysis. We derive the regime of stability against spin-Peierls ordering and argue that the DSL ground state might still be achievable in candidate materials, despite its tendency to valence bond solid ordering.</p>

3D stability of magnetotail Bz hump configurations
<p>Using three-dimensional MHD simulations, we explore the stability of magnetotail configurations that include a local enhancement of B_z (a ``B_z hump"), focusing on configurations that were found previously to be unstable in 2-D, neglecting cross-tail (y) variations as well as a cross-tail magnetic field component B_y. Not surprisingly, the 2-D unstable configurations were also found unstable in 3-D, developing 3-D structure after an initial rise as in 2-D. This is consistent with the fact that the selected B_z hump configurations are characterized also by a local tailward decrease of field line entropy, which has been found to govern ballooning/interchange (B/I) instability(Schindler and Birn, 2004). The evolution of the maximum electric field of the unstable 3-D modes showed an early exponential growth, whish was only modestly faster than the 2-D mode. This might suggest that the unstable ballooning regime extends from k_y \to \infty (proper ballooning modes) over finite k_y even to k_y = 0, at least for some equilibria. When the 3-D modes had evolved they grew significantly faster than the 2-D modes, associated with evolving into several narrow beams. The 3-D modes did not approach stable final configurations.</p> <p>The final 2-D configurations approached from the unstable ones were found to be unstable in 3-D. These findings are again consistent with the fact that the 2-D evolution, governed by ideal MHD, did not alter the characteristics of the entropy function.</p> <p> </p>

GEOLAB-SAFETY - Stability Analysis For Enhanced Tailings storage facilities
<p>This repository includes the outcomes of the GEOLAB Transnational Access project SAFETY, carried out at Deltares' geotechnical centrifuge facilities and coordinated by University of Porto. The main goal of SAFETY (Stability Analysis For Enhanced Tailings storage facilities) is to evaluate and enhance the stability of tailings storage facilities (TSF) under adverse conditions. These facilities, used to store the fine waste material (tailings) from mining processes, are prone to instability issues such as liquefaction, which can lead to catastrophic failures. The project focuses specifically on analyzing the stability of dry stack embankments—a more sustainable and potentially safer method of tailings disposal. The project has attempted to simulate the behavior of tailings dams through a series of centrifuge tests.</p> <p> </p> <p> </p>

Data for: Apparent stability masks underlying change in a mule deer herd with unmanaged chronic wasting disease
<p>The contagious prion disease "chronic wasting disease" (CWD) infects mule deer (<i>Odocoileus hemionus</i>) and related species. Unchecked epidemics raise ecological, socioeconomic, and public health concerns. Prion infection shortens a deer's lifespan, and when prevalence (proportion of adults infected) becomes sufficiently high CWD can affect herd dynamics. Understanding population responses over time is key to forecasting long-term impacts. Here we describe unexpected stability in prevalence and abundance in a mule deer herd where CWD has been left unmanaged. High apparent prevalence (~30%) since at least 2005 likely drove observed changes in the proportion and age distribution of wild-type native prion protein (<i>PRNP</i>) gene homozygotes among deer sampled. Predation by mountain lions (<i>Puma concolor</i>) may be helping keep CWD in check. Despite stable appearances, prion disease nonetheless impairs adult survival and likely resilience in this deer herd, limiting its potential for growth despite refuge from hunter harvest and favorable habitat and winter conditions.</p>

Data from: Habitat isolation reduces intra- and interspecific biodiversity and stability
<p>Fragmentation is predicted to reduce biodiversity and stability by increasing habitat isolation and impeding dispersal among patches. These effects may manifest at both the interspecific and intraspecific levels, yet few studies have simultaneously explored dispersal effects across levels of organization. We used field mesocosm experiments to examine how habitat isolation (in the form of dispersal rate) alters inter- and intraspecific stability and diversity in local zooplankton communities. We observed effects of increasing dispersal rate at both the intra- and interspecific levels. Increasing dispersal increased local species diversity and reduced mean temporal variability of populations. At the intraspecific level, <i>Daphnia pulex</i> clonal diversity was enhanced by dispersal and mean temporal variability of clone abundances through time was reduced.</p>
Data from: Biomass production and stability of five energycane cultivars at two latitudes in Georgia, USA
<p>Energycane (<i>Saccharum</i> hyb.) could be a viable bioenergy crop for the Southeast USA. Five energycane cultivars were planted in 2008 at a northern (Watkinsville, GA) and a southern (Tifton, GA) site, and were grown for seven years to compare biomass yields. Plots were arranged in a four replicate randomized complete block design at each site. Energycane was grown under rainfed conditions with 90–112 kg ha<sup>-1</sup> N applied annually. Plant height was recorded at least monthly, and stalks were sampled to determine juice volume and Brix (estimate of sugar concentration) at harvest. Whole plots were mechanically harvested each year after killing freeze and weighed to determine biomass yields. Biomass yield and mature plant height were strongly correlated at both Tifton (<i>r</i> = 0.746) and Watkinsville (<i>r</i> = 0.727). Biomass yields peaked in year four at Tifton (39.8 Mg ha<sup>-1</sup>) and year five at Watkinsville (30.5 Mg ha<sup>-1</sup>), but local weather conditions had a greater influence on yields than stand age. Day-long freezes during the winter and late spring freezes after shoot emergence resulted in reduced growth rate and yields in subsequent growing seasons. These cold weather events were more common at Watkinsville than Tifton, resulting in yields being more variable at the northern location. The greatest yielding cultivars were Ho 06-9001 (27.0 Mg ha<sup>-1</sup>) and Ho 06-9002 (25.1 Mg ha<sup>-1</sup>). Stability analysis revealed that these two cultivars responded positively to favorable environments in terms of biomass yield and plant height.</p>
