1. Towards a unified framework for multiple stable states in ecological systems.
PMID:日期:2026-09-23Multiple stable states-the coexistence of two or more distinct ecological configurations under identical environmental conditions-have attracted sustained interest in ecology, yet the field still lacks a unified framework connecting ecological mechanisms to dynamical models. Here, we review empirical and theoretical approaches to multiple stable states, synthesizing perspectives on stability, tipping, hysteresis and transient dynamics, and contextualize these within a common mathematical framework. Drawing on examples of well-known ecosystem models, we highlight the central and necessary role of positive feedback loops and identify other common, unifying features of ecological systems that exhibit multiple stable states. We further discuss the relationship between stable and transient dynamics, the roles of spatial and temporal scales in feedback identification and the implications for ecological restoration and management. We conclude with open questions and challenges for the field, including extending multistability theory to persistent-transient frameworks and harnessing emerging data-collection technologies to sharpen empirical inference.

2. Visual-inertial integration enables bumblebees to land on rapidly moving flowers.
PMID:日期:2026-09-23Landing on a moving target is challenging for flying animals, particularly under dynamic outdoor conditions. For pollinators such as bumblebees, wind-induced flower motion adds substantial complexity to landing manoeuvres. Here, we investigate how bumblebees (Bombus terrestris) land on laterally oscillating flowers. Using high-speed stereoscopic videography, we quantified three-dimensional flight kinematics of 48 bumblebees approaching a sinusoidally moving flower-mimic and analysed their control strategies using system-identification and control-theoretic modelling. Landing dynamics were consistent with combined visual (optic-flow) and angular yaw-rate feedback, enabling precise sideways tracking and gaze stabilization. Sideways motion was captured by a proportional controller, whereas gaze control required a proportional-derivative structure. Both controllers yielded similar case-specific effective delays (approximately 54 and 52 ms). Surprisingly, optic-target-angle contributed negligibly to gaze control, indicating reliance on velocity-based rather than position-based cues. Lateral acceleration correlated strongly with body roll, consistent with the helicopter model of force redirection. These results reveal a modular visual-inertial control strategy enabling robust landings on moving targets and suggest principles for agile bio-inspired flight.

3. Habitual non-rearfoot strike pattern attenuates impact loading during level and uphill running but not during downhill running.
PMID:日期:2026-09-23This study aimed to investigate the effects of uphill running (UR) and downhill running (DR) on impact loading and lower extremity biomechanics in runners with different habitual foot strike patterns (FSPs). Twenty-one habitual non-rearfoot strike pattern (NRFS) runners and 21 habitual rearfoot strike pattern (RFS) runners were recruited to run at 12 km h-1 at slopes of 10%, 0%, and -10% in a random order with their preferred FSPs on the instrumented treadmill. A motion capture system was used to synchronously collect marker trajectories. During UR and DR, 19% and 14% of the habitual RFS runners transitioned to NRFS, but the habitual NRFS runners kept using NRFS. NRFS runners had a lower vertical instantaneous loading rate during level running (LR) and UR but a lower vertical average loading rate only during UR than RFS runners. NRFS runners had lower knee and higher ankle impulse and cumulative load than the RFS runners. Habitual FSP is adaptable during graded running. NRFS attenuated impact loading during LR and UR, but not during DR, where its main biomechanical effect may be a redistribution of load from the knee to the ankle rather than an overall reduction in impact loading.

4. A functional basis for the developmental sequence of the macrostructure of the Venus flower basket (Euplectella aspergillum).
PMID:日期:2026-09-23Despite receiving significant interest from the biological and engineering communities, several questions about the underlying reasons for the form of the deep-sea sponge Venus flower basket (Euplectela aspergillum) remain unanswered. In particular, the basis for the sequence of emergence of three distinct macroscopic geometric features, while speculated upon, has not been validated. These features are (i) an interwoven cross-grid in the juvenile stage; (ii) a diagonal weave atop this initial grid; and (iii) a helical ridge that emerges in the mature phase of the sponge. This work uses computational design and additive manufacturing to fabricate models of each of these phases in sequence and subjects the models to mechanical tests in compression, bending and torsion. The results show that each feature has a singular advantage, even after accounting for the increase in mass associated with their addition: increased compliance for interwoven cross-grid, increased bending stiffness for diagonal weaves and improved torsional rigidity for the helical ridge. The work postulates that the prioritization of compliance in the juvenile phase and a transition to a stiffer structure in the mature phase is a strategy that enables the sponge to avoid high internal stresses and failure in its inherently brittle, silica-derived architecture.

5. Integrating machine learning and data-driven modelling: predicting dengue outbreaks and revealing spatially heterogeneous climatic drivers in Brazil.
PMID:日期:2026-09-16Dengue fever poses a major global health threat, with Brazil experiencing severe recurrent outbreaks driven by climatic, socio-economic and mobility factors. Accurate prediction remains challenging owing to dynamically shifting transmission patterns under intervention. This study employs a physics-informed neural network framework to integrate surveillance data with mechanistic models, inferring time-varying intervention parameters. The model demonstrates a strong capacity to fit state-level data from Brazil. Furthermore, it is used to generate 12-week forecasts for future dengue cases. Given the critical influence of climate on transmission dynamics, we also constructed separate eXtreme Gradient Boosting (XGBoost) models for individual states using epidemiological and meteorological data. SHapley Additive exPlanation (SHAP) analysis was applied to identify key climatic drivers and reveal significant regional heterogeneity. Our findings reveal that the drivers of the outbreak exhibit regional heterogeneity, and this geographical variation shows a strong correlation with the intensity of human activities and regional economic development levels. These insights into spatial heterogeneity and predictive modelling can inform the design of more effective, regionally tailored public health strategies for dengue control in Brazil.

6. Nonlinear viscoelastic effects of fascia: experimental findings and constitutive modelling.
PMID:日期:2026-09-16This study provides a comprehensive biomechanical characterization of the fascia lata, integrating systematic stress-relaxation protocols and, for the first time, dynamic mechanical analysis to resolve its complex dissipative mechanisms. Experimental tests were conducted along both longitudinal and transverse fibre orientations across multiple strain levels and frequencies to assess the synergistic effects of anisotropy, strain magnitude and loading rate. To describe these phenomena, three visco-hyperelastic constitutive frameworks were developed and compared: a first-order linear model (n=1), a generalized Maxwell model with two internal variables (n=2) and a nonlinear strain-dependent formulation. Results reveal a marked anisotropic viscoelastic profile, with the transverse direction exhibiting a significantly higher relaxation capacity (ratio of 0.666±0.144 at 2.5% strain) compared to the longitudinal axis (0.817±0.049), driven by the viscous flow of the interfibrillar ground substance. Although the tissue demonstrated marginal nonlinear viscoelasticity, the linear n=2 model outperformed the nonlinear n=1 framework, achieving superior predictive fidelity (R2=0.7321, NRMSE=0.1216 versus R2=0.7200, RMSE=0.2949 MPa). Results indicate that spectral refinement outweighs nonlinear complexity in this context. Specifically, the dual-branch linear approach captures the tissue's fundamental dissipation more effectively than a single-branch nonlinear formulation, which tends towards over-parametrization.

7. Cycling cadence selections at different saddle heights minimize muscle activation rather than energy cost.
PMID:日期:2026-09-16Unlike walking and running, people do not consistently choose cadences that minimize energy consumption when cycling. This suggests either that the neural control system for locomotion relies on indirect sensorimotor cues to energetic cost that are approximately accurate during walking but not cycling, or that an alternative objective function applies that correlates with energy expenditure in walking but not cycling. This study compared how objective functions derived as proxies to (i) energy cost or (ii) an avoidance of muscle fatigue predicted self-selected cycling cadences (SSC) at different saddle heights. Saddle height systematically affected SSC, with lower saddles increasing SSC and higher saddles decreasing SSC (n = 12). Both fatigue-avoidance and energy-expenditure cost functions derived from muscle activation measurements showed minima that closely approximated the SSCs. By contrast, metabolic power derived from VO2 uptake was minimal at cadences well below the SSC across all saddle height variations. The mismatch between the cadence versus muscle activation and the cadence versus metabolic energy relations is probably owing to additional energy costs associated with performing mechanical work at higher cadences. The results suggest that the nervous system places greater emphasis on muscle activation than on energy consumption for action selections in cycling.

8. Biomechanics and composition of fixed neurocranial tessellated cartilage from the neurocranium of four mobulid ray species with different depth ranges.
PMID:日期:2026-09-16Mobulidae are large filter-feeding cartilaginous fishes (Chondrichthyes) that migrate in the world's oceans. However, how their skeletal tissues have adapted to varying environments remains poorly understood. In this study, skeletal adaptations were investigated in four devil rays (Mobulidae), inhabiting various depth ranges from the surface (Mobula eregoodoo 0-50 m, Mobula thurstoni 0-100 m) to deeper water (Mobula mobular 0-1112 m, Mobula tarapacana 0-1896 m). However, since these are highly protected species, often with offshore, pelagic lifestyles, samples are difficult to obtain and are often preserved by freezing or fixation. Thus, the effects of formalin fixation were assessed on neurocranial samples from a ray (M. eregoodoo), a shark (Centroselachus crepidater) and a chimaera (Hydrolagus bemisi) before the mechanical and compositional properties of fixed neurocranial tessellated cartilage (n = 2 per species) were assessed in the four mobulid ray species using uniaxial compression, micro- and nano-indentation alongside assessments of mineralization, glycosaminoglycan (GAG) content and water distribution. During the fixation experiment, mechanical properties decreased by over 30%, possibly owing to leaching or water exclusion. With this effect in mind, the mechanical behaviour in mobulid rays displayed a decreasing trend among species with increasing depth ranges. No correlation between mechanical properties and GAG content or mineralization was found; however, water displayed a negative relationship with the mechanical properties. Collectively, these results suggest a more hydrated and compliant cartilage matrix in species with increased depth range compared with shallower species. This study provides the first account of energy dissipation, toughness, strength and relaxation behaviour of tessellated cartilage in chondrichthyans, revealing new insights into skeletal adaptation in cartilaginous fishes.

9. Uncovering the role of ionic doping in hydroxyapatite: the building blocks of tooth enamel and bones.
PMID:日期:2026-09-16Hydroxyapatite (HAp) is the primary mineral component of various mineralized tissues in the human body, including bone and teeth, where it performs critical roles of structural support and load transmission. In the context of dental health, the two most crucial properties of HAp are mechanical stability, which ensures resistance to forces, and chemical stability, which preserves surface integrity in acidic environments. During the early stages of human evolution, e.g. when teeth were used to crush uncooked food, mechanical stability was of paramount importance. However, with changes in diet and lifestyle, the principal origins of tooth damage and loss shifted towards bacterially mediated chemical attack, known as tooth decay, or caries. To enhance the chemical stability, ion doping has emerged as a particularly significant approach, and it lies at the focus of the present study. A molecular dynamics (MD) framework was developed to investigate the effects of ion doping on the chemical and mechanical stability of HAp and to identify optimal doping candidates. The framework combines conventional MD with steered molecular dynamics (SMD), thermodynamic integration (TI) and uniaxial compression test simulations to provide comprehensive insights into the doping process. The findings revealed surface atoms as the most viable candidates for doping, as demonstrated by SMD and conventional MD simulations. Notably, TI calculations have identified magnesium ions as a better candidate among the ions considered here for enhancing the chemical stability of HAp. However, uniaxial compression simulations revealed that increasing Mg²⁺ concentration simultaneously reduces the mechanical stability of HAp, highlighting a trade-off between chemical resistance and mechanical performance. By contrast, fluoride and carbonate substitutions showed comparatively minor effects on both properties. The results presented in this study offer valuable guidelines for synthesizing HAp-based substituent materials with properties tailored to meet the demands of modern dental applications such as implant coatings, enamel remineralization agents and restorative materials.

10. Signals too small to sense: physical and information-theoretic limits to induction-based magnetoreception in birds.
10. 信号太小而无法感知：鸟类基于感应的磁感受的物理和信息论极限PMID:日期:2026-09-16A recent study (Nordmann et al. 2025 Science 391, 1155-1160 (doi:10.1126/science.aea6425)) proposes that magnetoreception in pigeons may arise from electromagnetic induction within the semicircular canals of the inner ear. In this framework, motion through the geomagnetic field is suggested to generate an induced electromotive force that leads to ion redistribution in the endolymph, activation of voltage-gated calcium channels and subsequent engagement of downstream neural circuits. In this work, I examine the physical plausibility of this mechanism using a toy model of the induction process combined with an information-theoretic analysis. I find that, under idealized assumptions, Faraday induction in the semicircular canals would not generate a signal of sufficient informational content to support the extraction of directional magnetic field information from the geomagnetic field. However, the model supports the possibility of inferences due to radio-frequency electromagnetic waves of a miniscule amplitude, thereby providing a potential rationalization of their disruptive effect on avian compass navigation.
