Ecosystem transitions from bare to vegetated states often stall at early stages, before the biogeomorphic feedbacks needed for further expansion take hold. In aquatic systems, this bottleneck is especially common where inundation and hydrodynamic conditions may impose strong abiotic filters on pioneer establishment. Here, we integrate a manipulative field experiment with a simple probabilistic model to test whether tidal creek...
Precision measurement of the Ds*+-Ds+ meson mass differenceNARA Subscribed
Epigenetic age acceleration measures and chemotoxicity in older adults with early breast cancerNARA Subscribed
Among older adults with early breast cancer, the risk of chemotoxicity can vary widely despite similar chronological age. Here, we evaluated whether epigenetic indicators of biological age can stratify the risk of chemotoxicity in this population. In a prospective study of 394 women age > 65 with stage I–III breast cancer treated with neo/adjuvant chemotherapy, we analyzed peripheral blood DNA methylation patterns to estimate...
Healthy maternal metabolism is critical during pregnancy and lactation to support fetal development and protect against environmental toxins. Polychlorinated biphenyl 11 (PCB 11), a lower-chlorinated, non-legacy congener, is detected in human serum, including pregnant women and children; however, its impact during these sensitive life stages remains poorly understood. This study presents the first comprehensive hepatic proteom...
Functional Vulnerability Arises From Unsteady Trait‐Based Networks Despite High RedundancyNARA Subscribed
Theoretical models suggest that community functional redundancy buffers functional vulnerability because functions of lost species may be compensated by others, yet empirical evidence demonstrates this buffering effect to be weak. We hypothesised that this weak effect arises from differences in the structural arrangement of redundancy within communities. Therefore, we developed ‘community functional structural steadiness’, a n...
Stomatal closure is a pervasive response among trees exposed to flooded soil. We tested whether this response is caused by reduced hydraulic conductance in the soil-to-leaf hydraulic continuum ( k total ), and particularly by reduced root hydraulic conductance ( k root ), which has been widely hypothesized. We tracked stomatal conductance at the leaf level ( g s ) and canopy scale ( G s ) along with physiological conditions in...
Islands are model systems for testing and developing ecological theories. Despite extensive research on island biodiversity, the importance of the biogeographic context for biodiversity–stability relationships is poorly understood. We addressed this knowledge gap by integrating the Equilibrium Theory of Island Biogeography (ETIB) with a functional perspective to explore island biodiversity–stability relationships. We conducted...
