Summary: Coastal wetlands are vulnerable to sea-level rise, extreme climate, and human activities, especially in large river deltas. This study quantified the changes in area and patch number of coastal wetlands in China's four major river deltas, and assessed the effects of driving factors. It was found that the Liaohe River Delta and Yellow River Delta experienced substantial losses, while the Yangtze River Delta showed recent recoveries. The Pearl River Delta had a relatively stable area trend but an increasing patch number trend. Protected areas were effective in halting the decreasing trends in coastal wetland areas, but were counteracted by invasive plant invasions.

Summary: Enlarged TDLN in non-metastatic CRC exhibits an activated anti-tumour immune profile and is associated with favorable survival outcomes. The presence of numerous immune-activating pathways and higher numbers of CD3+ and CD8+ T cells in L-TDLN suggests its potential as a prognostic indicator.

Summary: Animals commonly exhibit a tendency to return to previously visited locations. This study compared patch fidelity and patch size preference between one bumble bee and one honey bee species foraging on patches of Medicago sativa L. Results showed that honey bees exhibited greater patch fidelity (76%) than bumble bees (47%), and honey bees were more likely to return to the patch where they were marked. Bumble bees showed a preference for larger patches and were more likely to return to them.

Summary: This article discusses the research progress of microbe-based cancer immunotherapy, inducing anticancer immunity through the preparation of nanoparticles of different sizes. The study found that the size of the formulations inversely correlates with their accumulation ability in tumor-draining lymph nodes, showing potential therapeutic effects.

Summary: Studying the interactions between paleoecology and climate variations in semi-arid areas, such as the Songnen grasslands in northeastern China, provides insights into how future vegetation changes and hydrological variations may impact semi-arid ecosystems. This study presents a high resolution palaeoecological dataset covering the past 7300 years and reveals the dynamics of vegetation and water levels in the Dabusu peatlands. By comparing these features with regional climate change, the study suggests that East Asian Summer Monsoon circulations might be the main driving force controlling the regional paleovegetation dynamics and hydrological variations.

Summary: In this study, thirty sediment samples were collected from the Gohar Rood River in Iran to evaluate the levels of different elements and their potential environmental risks. Using ICP-MS analysis, fifteen elements were measured, and it was found that chromium concentrations exceeded the Severe Effect Level (SEL) at all sampling sites. Zinc, manganese, cobalt, and chromium showed moderate contamination based on pollution index, modified pollution index, and enrichment factor. The modified hazard quotient indicated varying degrees of pollution severity for some elements. Regression analysis revealed that agricultural runoff, domestic, and municipal sewage were the main sources of zinc, copper, lead, antimony, and molybdenum in the riverine sediment. Additionally, the BCR fractionation scheme indicated medium to high risks to the local environment from manganese, cobalt, and zinc.

Summary: The study found that in the active layer of Arctic islands, Cd and Zn had larger labile pools with greater resupply capacity, while Pb had a smaller resupply capacity. Cd and Zn could rapidly resupply, while Pb's resupply was slower. Changes in landscape elevation can affect soil texture and other conditions, thus impacting the resupply processes of Cd, Zn, and Pb.

Summary: This study investigates the influence of spatial heterogeneity in plant-soil feedbacks (PSFs) on plant growth and finds that patch size and contrast of PSF heterogeneity can influence plant growth. Different types of heterogeneous soils have different effects on the growth of different plants, possibly due to differences in root growth under different soil conditions. The results demonstrate the significance of PSF heterogeneity in plant growth.

Summary: As temperatures rise, monitoring changes in habitat conditions for aquatic species becomes increasingly important. The ECOSTRESS instrument provides temperature data that can assess fluctuations in thermal habitat suitability and evaluate the impact of wetland restoration projects. The study found that key Delta Smelt habitat areas had high thermal suitability, but heatwave events resulted in decreased suitability. ECOSTRESS data indicated a potential decrease in surface water temperature in tidal restoration areas, but more research is needed. This study is important for understanding ecosystem conditions and the effects of wetland restoration projects on water temperature.

Summary: The study shows a coupled relationship between tree growth and heatwaves, with increased heatwave frequency since 1996 leading to a significant decline in tree growth in large forest patches. However, the relationship between tree growth and heatwaves remained in medium and small forest patches after 1996. Landscape heterogeneity, such as patch size and slope position, can alleviate the pressure of temperature warming and reduce rapid decline in tree growth under high-frequency heatwaves in Mongolia Plateau.

Summary: In this study, a single remote sensing image (RSI) dehazing method based on robust light-dark prior (RLDP) is proposed. The method is robust to outlier pixels and utilizes a hybrid model. It first removes haze using a robust dark channel prior (RDCP), and then removes shadows using a robust light channel prior (RLCP). A cube root mean enhancement (CRME)-based stable state search criterion is also proposed to tackle the challenge of patch size setting. Experimental results on benchmark and Landsat 8 RSIs demonstrate the effectiveness of the RLDP method in haze removal.

Summary: The study proposes a hierarchical method to accurately model the size and frequency of forest disturbances, improving the representation of the size-frequency distribution of forest disturbances; the results show that between 2000 and 2005, forests in most provinces in China were dominated by moderate disturbances, while small disturbances were most common in southeastern provinces and very large disturbances were mainly found in northeastern and northwestern provinces.

Summary: Research shows that large patches can trap more shells and facilitate plant regrowth, enhancing their own persistence. In contrast, small patches without enough plants cannot persist, with a critical threshold of around 20 square meters below which ecosystem collapse occurs.

Summary: Excessive nutrients from agricultural activities are a major factor in global water quality impairment. The expertise in water and runoff management in Europe's Northern Periphery and Arctic (NPA) areas needs improvement. This research provides a comprehensive review of Good Agricultural Practices (GAPs) in the NPA region and suggests incorporating phosphorus retaining media to enhance nutrient reduction and recovery.
