Summary: The research revealed that soils from first-rotation rubber plantations were more impacted by previous natural forests in terms of SOC stock, while second-rotation plantation soils had lower SOC levels. Significant losses in SOC pools were observed between natural forest and rubber plantations, particularly within the initial 10 years of conversion.

Summary: This study proposes a methodological framework to analyze landscape connectivity for Asian elephant habitat conservation. The results showed that vegetation restoration significantly improved the connectivity between habitats and the first few new habitat patches played an important role in improving connectivity. These findings can be used as guidance for improving fragmented Asian elephant habitats and habitat restoration of other endangered species.

Summary: In southwestern Yunnan Province, China, the habitat suitability for wild Asian elephants is strongly influenced by forest fragmentation and percentage cover, while human activities and infrastructure have a relatively minor effect. Approximately 17,430 km2 of highly suitable habitat for elephants were predicted in Yunnan, with 90% of it being outside currently protected areas.

Summary: This study aimed to analyze how cognitive biases affect residents' willingness to participate in ecological restoration and provide a valuable reference for policy design. Through a survey of 655 urban residents, the study quantified the cognitive biases regarding the eco-consequences of natural rubber expansion and examined their impact on residents' willingness to participate in restoration programs. The results showed widespread cognitive biases among urban residents in Hainan, which decreased their willingness to participate. The study also found that ecological consciousness moderated the effects of cognitive biases on residents' willingness and degree of participation.

Summary: A study was conducted on 45 diverse Asian and African populations of pearl millet to assess their fertility restoration ability on three cytoplasmic male sterility (CMS) systems. Genetic variation was found for yield-related traits and populations were grouped based on their origin. Fertility restoration frequency varied among the CMS systems, with some populations identified as potential sources for maintainer or restorer lines.

Summary: Using choice experiments and field surveys, this study revealed the public's preference and willingness to pay for natural rubber plantation restoration projects. The results showed that residents of Hainan Province had a positive attitude towards ecological restoration for rubber plantations and were willing to bear personal costs. The study also identified the restoration scenario that would generate the highest social benefits, emphasizing water source protection, state farms, and under-forest breeding economy. The findings highlight the importance of considering public preferences in ecological restoration policies.

Summary: Due to global warming, agriculture has been negatively affected, making it crucial to study the impact of agricultural productive services on farmers' climate-responsive behaviors. This paper conducted a questionnaire survey and statistical analysis among maize farmers in Jilin Province, China, finding that agricultural productive services significantly influence the choices and intensity of climate-responsive behaviors. Policy recommendations are proposed for establishing a robust agricultural social service system and strengthening support for agricultural productive services.

Summary: Mobile edge computing and multi-drone aided space-air-ground integrated Internet of Things networks can provide high-quality wireless access and computing services for ground IoT devices. However, diverse tasks, moving drones, and limited network resources pose great challenges for task offloading and resource allocation schemes. This paper investigates inter-server computation offloading, resource allocation, and drone deployment to minimize the overall computation overhead of all ground IoT devices.

Summary: A mechanistic model was developed to assess the removal efficiency of pollutants in a wetland system, particularly in oil sands process-affected water (OSPW). The model simulated wetland mechanisms of chemical removal and showed that sustained wetland treatment is feasible. It is a helpful tool to evaluate the feasibility of treatment systems and to assess trade-offs in wetland design and operation.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
