Summary: Harmful algal blooms caused by Heterocapsa bohaiensis have been occurring in aquaculture areas near Liaodong Bay, China since 2012, resulting in mass mortality of Eriocheir sinensis larvae and significant economic loss. This study investigated the interspecific competition between H. bohaiensis and Chlorella pyrenoidosa to understand why H. bohaiensis dominates the phytoplankton community. The results showed that H. bohaiensis achieved competitive advantage through exploitation competition, rather than allelopathy.

Summary: This study aimed to investigate the effects of exposure to domoic acid (DA) on the marine diatom Phaeodactylum tricornutum. The results showed that exposure to DA led to an increase in reactive oxygen species (ROS), as well as changes in antioxidant capacity. The enzyme activities and antioxidant content in the diatoms were significantly affected by DA exposure.

Summary: Glacier algae residing on the surface ice of the southwestern Greenland Ice Sheet show lower cellular nutrient content and elevated C:N and C:P ratios, indicating adaptation to oligotrophic environments. This lower nutrient requirement may aid the proliferation of glacier algal blooms in nutrient-poor cryospheric regions in a warming world. Up-scaling of observations suggests the potential for glacier algae to accumulate significant amounts of carbon and nitrogen within surface ice locations, confirming previous modeling estimates.

Summary: In mixed species forests, the effects of soil fertility on belowground processes were investigated. Fertilization increased competition between species, leading to partial exclusion of Acacia fine roots from nutrient-rich topsoil. Eucalyptus roots explored soil near Acacia trees more in unfertilized stands, indicating facilitation through higher soil N availability and direct N transfer from Acacia trees.

Summary: Allelopathy, the phenomenon of one plant species affecting the growth of another, is common in marine, brackish, and freshwater habitats. It can provide a competitive advantage for some phytoplankton species and may influence species succession and bloom development. Understanding the interactions of allelopathy with other factors is crucial for future research in this field.

Summary: Plant-derived allelochemicals have the potential to mitigate harmful algal blooms (HABs), but their effects can vary among different algal species. In this study, we investigated the allelopathic effects of two newly identified allelochemicals, 1,2-benzenediol (1,2-BD) and 3-indoleacrylic acid (3-IDC), on six algal species. We also evaluated the specific allelopathic responses of two bloom-forming species, Microcystis aeruginosa FACHB-905 and Heterosigma akashiwo, to 1,2-BD. The results showed that 1,2-BD had a broader antialgal spectrum and consistently inhibited the growth of M. aeruginosa FACHB-905, while H. akashiwo displayed resistance to 1,2-BD.

Summary: Ecological interactions influence evolutionary dynamics by selecting upon fitness variation within species. Antagonistic interactions often promote genetic and species diversity, despite the inherently suppressive effect they can have on the species experiencing them. In this review, the authors discuss how certain single-celled and dimorphic fungi have evolved allelopathic killer phenotypes that engage in antagonistic interactions, and explore the evolutionary pathways, functions, and consequences of killer phenotypes. They highlight that killer phenotypes are powerful models for studying allelopathic antagonism, but their evolutionary ecology remains largely unknown. The authors discuss what is known and what remains to be ascertained about killer phenotype ecology and evolution.

Summary: A new type of S-scheme heterojunction photocatalyst constructed from BiOCl and CuBi2O4 shows enhanced catalytic performance in removing aqueous diclofenac and gaseous nitric oxide under visible light irradiation. The improved performance is attributed to enhanced charge separation and transfer, tuning of oxygen vacancies to enhance oxidation ability, and a proposed photocatalytic reaction mechanism based on the S-scheme heterojunction structure.

Summary: This study designed Mn3O4/CuBi2O4 with dual redox cycles of Mn(III)/Mn(IV) and Cu(I)/Cu(II) to efficiently degrade and mineralize diclofenac sodium (DCF). The activation mechanism of PMS by Mn3O4/CuBi2O4 was proposed, and possible degradation pathways of DCF were suggested based on detected degraded products and toxicity evaluation results. This work may be useful for developing stronger heterogeneous activators of PMS for more efficient wastewater purification.

Summary: Selective conversion of methane into value-added chemicals is a promising approach for efficient utilization of hydrocarbon sources. In this study, the authors developed dimeric copper centers supported on graphitic carbon nitride (Cu-2@C3N4) as advanced catalysts for partial oxidation of methane. The copper-dimer catalysts demonstrated high selectivity in both thermo- and photocatalytic reactions, with hydrogen peroxide and oxygen being used as the oxidizer, achieving >10% conversion and >98% selectivity toward methyl oxygenates.

Summary: Constructing novel Z-scheme heterojunctions can greatly enhance the performance of photocatalysts. In this study, TCPP/G/BMO exhibited exceptional visible-light activity for the degradation of tetracycline and reduction of Cr(VI), showing significant improvement compared to sole Bi2MoO6. The enhanced activity is attributed to the synergy effect of the Z-scheme charge transfer mechanism and improved light absorption.

The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
