Summary: Theoretical predictions of a large number of classical Cepheids in the mass range of 3-11 M are not supported by measured data, which mainly falls between 3.6-5 M. This discrepancy hinders our understanding of the mass-luminosity relation and the Leavitt Law. By analyzing a new group of Cepheids in double-lined binary systems, this project aims to provide mass determinations in a wide range and study their evolutionary processes. Through spectroscopic studies of a subsample of 18 brightest candidates, it was found that lines of two components were detected in the spectra, significantly increasing the number of Cepheids in SB2 systems.

Summary: This study selected 41 cities in the Yangtze River Delta region to measure the spatial and temporal evolution of the allometric growth relationship between population and land, and explore the mechanism of the effect of allometric relationships on the economic agglomeration effect. The results show that the population-land allometric growth transitions from population to land expansion, and the economic agglomeration effect is classified into four types. The study suggests actively regulating the incongruity between population growth and land expansion to promote the evolution of cities towards an intensive type of population-land coordination.

Summary: Predictive models were generated to assess the absorption of nine metals by the different parts of forage sorghum in growing media mixed with poultry manure. The roots exhibited the highest metal contents. Bioaccumulation factor (BAF) values were < 1 for some metals and > 1 for others. Translocation factor values were < 1 for all metals except for Co, Cr, and Ni. The predictive models showed a high level of data precision and can be used to ensure the safety of growing forage sorghum in media fortified with poultry manure.

Summary: Lead contamination poses a significant threat to the environment, and the phytoextraction approach using tolerant and metal-accumulating plants is recommended for soil remediation. This study assessed the phytoremediation potential of three Sorghum bicolor cultivars (S1, S2, and S3) for lead-contaminated soil. The results showed that all cultivars could grow to maturity in high lead soil, but lead affected their morphology and chlorophyll contents, especially at 800 mg/kg. None of the cultivars were considered lead hyperaccumulators, but they were identified as suitable for phytostabilization.

Summary: Oxygen deprivation caused by waterlogging reduces crop productivity, including the oil-producing crop Brassica napus L. This study investigated the early responses of B. napus plants to waterlogging by over-expressing or down-regulating class 1 (BnPgb1) and class 2 (BnPgb2) phytoglobins (Pgbs). Suppression of BnPgb1 exacerbated the decrease in gas exchange parameters and plant biomass, while suppression of BnPgb2 had no effect. Over-expression of BnPgb1 attenuated waterlogging symptoms and activated the antioxidant system and transcriptional induction of folic acid (FA), which could contribute to plant tolerance to waterlogging stress.

Summary: With the increasing demand for electronic devices, e-waste containing hazardous heavy metals is becoming a major environmental threat. This study evaluates the phytoremediation potential of Cyperus rotundus L. in soils contaminated with battery scrap waste (BSW), specifically for the heavy metals cadmium (Cd) and lead (Pb). The results showed that BSW mixing significantly increased the heavy metal content in the soil, resulting in reduced growth and biochemical traits of C. rotundus. However, C. rotundus was found to be a hyperaccumulator plant capable of absorbing Cd and Pb, making it a potential candidate for phytoremediation of BSW-contaminated soils.

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.
