The integrity and stability of the ecosystem are fostered by recognizing and protecting areas that are essential to maintaining the resilience of the ecological network. Research in the field of ecological network resilience has garnered attention in recent years, although the necessity of developing various assessment methods for network resilience is evident. Taking the Hyrcanian Forest ecosystem as a case study, this research aimed to identify the most important areas of the ecological network in maintaining and enhancing the resilience. To achieve this goal, first, a combination of the morphological spatial pattern analysis method and the assessment of the significance of ecosystem services was used to extract ecological source areas. Next, utilizing circuit theory and the least-cost path method, a network connecting sources was constructed, and pinch points were identified. After that, high-risk areas in ecological sources were found using the habitat risk assessment method. Using this integrated approach leads to the identification of valuable areas that are vulnerable to human threats and disturbances. Finally, the node removal method coupled with the calculation of network resilience indices, connectivity, and efficiency was employed to prioritize conservation areas. The results of the study indicated that the most important nodes were located in the northern edges of the forest, which have been under threat in recent years. Additionally, the region ranked moderately in terms of connectivity, indicating the importance of focusing on the conservation of forest patches before the complete fragmentation of the area. Furthermore, our findings underscore the importance of considering landscape connectivity and ecological network resilience in conservation planning for policymakers and managers aiming to protect biodiversity in the Hyrcanian Forest ecosystem.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":"21 3","pages":"570-582"},"PeriodicalIF":3.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144007307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Constructing ecological networks is vital in improving landscape connectivity, protecting biodiversity, and maintaining regional sustainable development. Ningbo, China, was set as the research area. Geographic information system and morphological spatial pattern analysis (MSPA) were used to determine the ecological source area. Subsequently, the corridor design model Linkage Mapper was used to ascertain and assess the linkages between the designated ecological source areas. The results showed that from 2000-2020, there was a large-scale change in land use type in Ningbo, with increasing complexity of patches and landscape fragmentation. The ecological sources of the three periods in Ningbo were primarily situated in the western, southern, and Hangzhou Bay coastal regions, exhibiting an uneven distribution in the eastern and western areas. The number of primary ecological corridors in Ningbo underwent a significant reduction, from 26 to 17, between the years 2000-2020. In terms of the distribution of ecological corridors, the primary corridors were concentrated in the central, southern, and western regions of the study area in 2000. By 2020, however, the primary ecological corridors within the study region were distributed mainly in a southerly direction. The interaction between north and south ecological sources was weakened, which adversely affected the species spread and ecosystem stability. After optimization, 12 ecological corridors and four ecological nodes were incorporated into Ningbo, 67 ecological breakpoints were identified, and four stepping stone patches were added. The study used spatiotemporal change trends, including land use type and landscape pattern, to examine the ecological network of Ningbo.

The coagulation process shows treatment efficiency in terms of turbidity and suspended solids removal. However, despite good results, coagulant selection is not an easy task. A coagulant can effectively remove suspended solids but, at the same time, increase conductivity; coagulants can also significantly increase chemical sludge production. The final selection of coagulants depends on the importance attributed to the parameter desired to be removed. In this study, the use of multicriteria decision-making is proposed to help select organic coagulants and hybrid coagulants, which have emerged as an alternative to inorganic coagulants in recent years due to the disadvantages of chemical coagulants and whose use and variety are increasing. Therefore, starting from the parameters determined by coagulation process results, these techniques allow weighting these parameters according to the judgments of drinking water treatment plant professionals and determining priorities among coagulants. The agreement between the obtained results and the literature shows that the analytical hierarchy process (AHP) method is a useful tool for selecting coagulants. According to the results of the AHP matrix created with four criteria and nine alternatives, it was found that hybrid coagulants with similar performance to inorganic coagulants have not yet been adopted by drinking water treatment professionals. This may have been due to the higher price of hybrid coagulants and the fact that they are not yet widely used in the drinking water industry.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"614-627"},"PeriodicalIF":3.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the dynamics and interactions between birds and drilled fields is crucial for developing sustainable farming practices that balance agricultural food production with wildlife conservation. This study focused on the attractivity of freshly drilled onion and carrot fields to birds and the potential exposure of birds to the pesticide-treated onion and carrot seeds available on the soil surface after drilling in Minas Gerais, Brazil. Bird surveys were conducted using scan sampling and point count methods to assess diversity and behavior before, on the day of drilling, and after drilling. Carrot fields showed a decrease in observed species and individuals on the day of drilling, with an increase in bird sightings after drilling. Similar trends were observed in onion fields, with the species composition changing after drilling and a significant decrease in abundance on the day of drilling. None of the species found foraging in the field after drilling were granivorous or omnivorous. Seed exposure was assessed by counting available seeds on the soil surface at different time points after drilling. Seed exposure was higher in the field border than in the field center. These findings indicate that carrot and onion fields offer limited food sources for granivore bird species probably due to low seed availability and intensive seedbed preparation. The research also suggests that freshly drilled carrot and onion crops are unattractive to foraging birds, with low seed exposure and a reduced likelihood of contact with pesticides applied as a seed treatment.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":"665-673"},"PeriodicalIF":3.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12047015/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Runoff containing these products can contribute elevated biochemical oxygen demand (BOD) to receiving streams. We monitored runoff from Milwaukee Mitchell International Airport at one upstream site, three outfall sites, and one downstream site from 2005 to 2022 for BOD, chemical oxygen demand (COD), and freezing point depressants used in deicing and anti-icing fluids to determine the primary sources of BOD and COD in the receiving stream. The greatest concentrations of BOD, COD, and freezing point depressants occurred at the primary outfall, which drains the main terminal area, and the secondary outfall, which drains cargo operations. The greatest loadings occurred at the primary outfall; loadings were an order of magnitude less at the secondary outfall due to a small drainage area with relatively low flow volumes. At the three outfalls, median concentrations of five-day BOD (BOD5) and COD were 100-1,300 mg L-1 and 200-2,100 mg L-1 respectively. Apportionment computations indicated that propylene glycol from aircraft deicers and anti-icers was responsible for at least half of the BOD5 and COD concentrations and loadings. Acetate from pavement deicers contributed another 7%-15% at each site. These findings suggest that management actions in the primary outfall drainage area that target propylene glycol-containing deicers have the greatest potential to decrease BOD5 in airport runoff.

The EFSA 2023 Guidance suggests to rank FS candidates for each dietary group according to their expected exposure by estimating a species-specific daily dietary dose (DDD). Species experiencing higher exposure would be ranked as potentially more vulnerable and can be identified as FS candidates. The DDD is calculated using an estimated \"proportion of diet an individual obtains from the (treated) crop\" (PT). A PT is derived from a radio-tracking field study in the crop of interest, but such data are not available for all species. We introduce the frequency of occurrence in surveys (FOsurvey) in each study field from FS field studies as a proxy for PT in theoretical DDD calculations. The presence of a species during a high proportion of surveys, resulting in a high FOsurvey, could indicate a high proportion of foraging time spent in this crop. To evaluate whether FOsurvey is an appropriate proxy for PT, empirical PT values from radio-tracking studies for different bird species were correlated to respective FOsurvey values from FS studies in the same crop and growth stage. Based on 10 case examples covering different species and crops, a positive correlation was shown between PT and FOsurvey, supporting the suitability of the proposed approach. Based on a positive correlation between the species' prevalence and the new theoretical DDD, the list of the most relevant FS resulting from the new ranking approach is not expected to differ significantly from the FS selection, according to the methodology proposed in EFSA 2009.
