Summary: Previous studies have focused on the direct impact of temperature on the foliar uptake of persistent organic pollutants (POPs), but few studies have explored the indirect impacts of low temperature on foliar uptake. Our study at the treeline on the Tibetan Plateau found that colder climate conditions led to enhanced surface adsorption and slower penetration of dichlorodiphenyltrichloroethanes (DDTs) in leaves, resulting in higher uptake efficiencies and reservoir capacity. The relative humidity, correlated with temperature, also influenced the uptake rates of DDTs.

Summary: This study aims to investigate the molecular architecture and function of Prdxs in marine invertebrates, as well as to clarify their protective role against metal-induced stress. The results show that the expression of Prdx2, -3, and -4 is correlated to metal accumulation, and the increase in enzyme activity after Zn exposure is slower compared to Cu and Cd.

Summary: The study found that children from HIV-affected families faced barriers to vaccination, especially when the mother was HIV-positive, which increased the risk of missed vaccinations. However, local vaccination centers and outreach workers played a key role in increasing vaccine uptake.

Summary: Global tropical deforestation rates are rising, particularly in arable landscapes of West Africa where remaining forest fragments are highly fragmented. This study aims to inventory and characterize these forest patches using remote sensing, finding that while larger patches may experience more loss on average, smaller secondary forest patches persist in the landscape. Larger forest patches also harbor denser tree cover and higher trees, indicating potential resilience to human pressures.

Summary: In tropical areas, where there is high atmospheric nitrogen deposition and low soil phosphorus availability, tropical plants need to adapt their nutrient-use strategies in order to maintain growth and survival. This study investigated the adaptive strategies of eight plant species in primary and secondary tropical forests under low soil phosphorus availability. The results showed that the plants responded differently to phosphorus addition in the two forest types, indicating the ability of tropical plants to adjust foliar phosphorus allocation in order to regulate photosynthetic rates and acclimate to low phosphorus environments.

Summary: This study presents a geochemical profile of the East Kolkata Wetlands and evaluates its efficiency in treating municipal and industrial wastewater. The concentrations of trace metals in untreated pond waters and sediment were analyzed. The results show that the bioremediation of wastewaters containing certain metals was not uniform in all the ponds, with some metals like Zn and As unable to be removed effectively. Mass balance calculations indicated the reduction in differential load after microbial treatment for different metals.

Summary: This study found that foliar dust is more suitable for environmental monitoring in urban soil-plant systems than soil and plant materials, and plays a significant role in shaping the elemental composition of plant leaves. The elemental composition of plant leaves differs significantly among different soil-plant systems.

Summary: The study investigated the effects of nitrogen and phosphorus fertilization on soil and foliar mineral nutrient concentrations in a tropical forest in southern China. Results showed that nitrogen addition reduced soil exchangeable cations and foliar mineral nutrients, while phosphorus addition increased soil pH and decreased foliar copper concentrations. It was also found that there were no observed adaptive mechanisms in the studied species to maintain foliar nutrient concentrations under high nitrogen supply.

Summary: The availability of soil nitrogen and phosphorus has a significant impact on the stability of soil organic carbon. This study examined how different fractions of soil organic carbon and the soil microbial communities in a tropical forest are affected by soil nitrogen and phosphorus availability. The results showed that phosphorus addition increased soil microbial activities and promoted the decomposition of recalcitrant soil organic carbon, while nitrogen addition increased the abundance of active soil organic carbon.

Summary: This study investigated the impact of the monsoon season on heavy metal loads in the sediments of the Hooghly River in India from 2014 to 2017, a previously unexplored time frame. The results revealed significant correlations between certain metals, suggesting contributions from industrial activity. The monsoon season was found to significantly increase the transport of metals, mainly due to weathering of continental detritus. The levels of certain metals, especially nickel, posed a significant threat to the aquatic ecosystem.

Summary: This study examines forest loss trends and patterns, as well as its impacts on ecosystem services, in the dry deciduous forests of West Bengal. Using remote sensing data and local perceptions, the study finds that logging and agricultural clearing are the dominant drivers of forest loss, with the highest rates observed in dense forests. The decline in provisioning ecosystem services, particularly wild foods and medicinal plants, is widely perceived by local households.

Summary: This study mapped forest canopy density in 2016 using two different methods: the semi-expert FCD mapper model and a new model developed by the researchers. The results showed that the modified model is more accurate than the semi-expert FCD model, providing a more detailed canopy density map.
