Summary: Conical intersections have a significant impact on molecular dynamics and chemical properties. In this paper, we predict nonadiabatic effects in an ultracold atom-ion charge-exchange reaction induced by laser-induced conical intersections. The interference effects in charge-exchange rate coefficients between K and Ca+ are irregular due to the presence of two licis.

Summary: Light competition plays a key role in shaping plant height across the plant kingdom, and the outcome of plant height evolution is influenced by factors such as competitive costs and benefit functions. Different combinations of these factors can lead to diverse evolutionary consequences, with power-type and Hill-type costs revealing complex evolutionary dynamics. The study sheds light on the mechanisms behind the high diversity of plant heights in nature.

Summary: The study demonstrates that diel light cycles have a significant impact on phytoplankton competition and biogeography in the global ocean. Diel nutrient cycles induce changes in the abundance of phytoplankton groups, favoring opportunists over gleaners. This impact weakens as latitude increases due to the dominance of the seasonal cycle.

Summary: This study demonstrates that selective regulation on asymmetric photopolymerization can be achieved by the arbitrarily coupled irradiation with CPUV and CPVL, either constructively amplifying chirality or destructively changing the helical preference of polymer chains. The work highlights the importance of the chiral induction effect in the helical chain propagation process and provides a deeper understanding of the helical preference in CPL-triggered asymmetric photopolymerization.

Summary: This study found that the successful invasion of the annual plant species Pedicularis kansuensis was due to the reduced coverage of native grasses, providing sufficient light resources. However, nitrogen enrichment can effectively inhibit P. kansuensis invasion by increasing the photocompetitive advantage of native species. The invasion of P. kansuensis has some impacts on plant community, but has little effect on plant community structure and soil properties.

Summary: Plants can respond to competition through physiological or morphological changes, affecting their foraging strategy. This study found that simulated competition enhanced metal accumulation in the metal hyperaccumulating plant A. halleri, especially in less metal-tolerant plants from non-metalliferous soils, with a stronger response for zinc over cadmium. The results support the idea that metal accumulation by hyperaccumulating plants may be facultative and change based on competition-induced demand.

Summary: Riverine macrophytes play crucial ecological roles in river ecosystems, but their growth models have received relatively limited attention compared to other aquatic or terrestrial plants. This systematic review reveals that current models often overlook important factors such as shading and the role of macrophytes in nutrient cycles. Future research should focus on exploring these factors and developing a conceptual framework to guide macrophyte growth modeling. Emphasizing modularity and accessibility is also important for improving efforts to model and manage riverine ecosystems.

Summary: Bryophytes can play a significant role in ecosystem processes and hold potential as bio-indicators for monitoring environmental pollution. This study examined the effects of NO3- pollution on the elemental composition of aquatic and semi-aquatic bryophytes and identified suitable species as bio-indicators. Higher NO3- concentrations were found in spring water from intense farming and urban areas, positively correlated with N content and delta N-15 isotope ratio in bryophytes. Apopellia endiviifolia and Oxyrrhynchium speciosum were highlighted as promising candidates for bio-indication of aquatic NO3- pollution.

Summary: This study investigated the seed production, seed banking, and germination cues of sub-tropical Vallisneria americana. It was found that the seeds of sub-tropical populations were dormant and could only germinate in the presence of organic material, light, or following scarification. Germination rate was enhanced by the presence of low-oxygen organic sediments and ethanol. These findings suggest a germination strategy focused on exploiting openings in existing vegetation following disturbance.

Summary: Constructed wetlands treating runoff from agricultural catchments can reduce nutrient load of water, but they can also be significant sources of greenhouse gases, especially methane. This study assessed methane emission potentials and phosphorus removal efficiency in a 0.45 ha in-stream surface flow constructed wetland, and analyzed the temporal dynamics of methane emissions and phosphorus removal over a nearly 4-year period. The results showed a clear seasonal dynamic in phosphorus removal efficiency and an increasing trend in methane emissions over the years, with the majority of methane fluxes occurring during the warm period. Maintenance of the wetland and regular removal of aboveground vegetation can reduce methane emissions, and regular sediment removal is also necessary due to phosphorus saturation.

Summary: Nutrient availability and light intensity play important roles in the expansion of amphibious clonal plants from terrestrial to aquatic habitats. High nutrient levels and light conditions promote the growth of the apical portions and overall performance of the clones. Maintaining clonal integration can benefit the expansion of the plants by optimizing resource utilization. These findings have implications for predicting community dynamics and vegetation restoration in ecotones like wetlands.
