This study explored geographical variation in seasonal habitat of\u0000 D. gigas\u0000 off Peru and the Eastern Pacific Equator using maximum entropy (Maxent) model, with fishing occurrence data and environmental variables including sea surface temperature (SST), sea surface salinity, net primary production (NPP), photosynthetically active radiation (PAR), chlorophyll\u0000 a\u0000 concentration, eddy kinetic energy, and sea level anomaly. Results indicated that all the environmental variables exhibited conspicuous seasonal and geographical differences off Peru and the Eastern Pacific Equator. On the basis of the percent contribution from the Maxent model, seasonal and spatial extents of habitat were largely explained by SST, NPP, PAR, and eddy kinetic energy in the Eastern Pacific Equator and SST, sea surface salinity, NPP, and PAR off Peru. Suitable ranges of each environmental variable differed between regions and were controlled by the seasonal variability. Furthermore, movement patterns of longitudinal and latitudinal gravity centers of fishing effort of\u0000 D. gigas\u0000 were consistent with spatial and temporal distribution of suitable habitats but showed dramatically geographical variations off Peru and the Eastern Pacific Equator. Our findings highlighted Maxent mode’s ability in exploring Humboldt squid habitat hotspots in the Eastern Pacific Ocean and suggested that constructing the habitat model for\u0000 D. gigas\u0000 should consider the geographical differences under environmental conditions.\u0000","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47919036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The impact of land and water use on different types of ESs has been extensively studied, but it has not been directly linked to its societal drivers, thus failed to explain the societal root cause of ES degradation. This paper aims to examine the impacts of 3 generic societal drivers: societal value, institutional governance, and science and technology development on the evolution of ESs in the Heihe River Basin, China since 2000 years ago. Water provision, food provision, groundwater maintenance, climate regulation, and environmental flow maintenance were examined as the major ESs. Content analysis method was used to track the change of the 3 societal drivers from various textual documents. It was found that there were strong trade-off relationships between food provision and groundwater maintenance in midstream and the environmental flow maintenance services in downstream. The slow-changing and independently developed societal drivers failed to adaptively respond to the increasing food provision demands while addressing the significant decrease in groundwater and environmental flows. It is concluded that rational water (re)allocation and use are the prerequisites of balanced development of different categories of ESs and linking societal development to the benefits humans obtain from ecosystems is the prerequisite for sustainable ES management.","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41957494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The understanding on the co-impact of upwelling–downwelling processes to physical–biological parameters that affect the CO 2 flux in the region is limited. This study aims to determine the factors and trends influencing the flux. We found that upwelling (downwelling) overlapped with the Northeast (Southwest) Monsoon as evidenced by the high (low) daily averaged chlorophyll-α concentrations. Increased chlorophyll-α with a mean of 1.70 mg m −3 was observed in the upwelling period, whereas in the downwelling period, it decreased to 0.49 mg m −3 . The CO 2 flux correlated with the seawater temperature and wind speed. The CO 2 flux was negative, −2.33 mmol m −2 day −1 (positive, 0.54 mmol m −2 day −1 ), in the upwelling-Northeast Monsoon (downwelling-Southwest Monsoon) season. On the climatological hourly timescale, this pattern showed that during the downwelling-Southwest Monsoon season, there were durations of increased, positive pulses of CO 2 flux, possibly because of higher temperatures, lower wind speeds, and low levels of chlorophyll-α. Conversely, in the upwelling-Northeast Monsoon season, there were periods of decreased flux, which occurred briefly during the day because of increasing concentrations of chlorophyll-α and at night due to lower temperatures and higher wind speeds.","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135549436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

However, the relative importance of co-varying climatic and edaphic controls on plant δ15N remains somewhat unclear. To address this issue, regional-scale plant (L. chinensis) and soil samples were collected along a longitudinal transect across the temperate grasslands in northern China. The influences of climatic and edaphic factors on the plant δ15N were disentangled using the variable importance in projection (VIP) approach. We found that the climatic and edaphic variables explained 52.4% and 31.2%, respectively, of the variation in plant δ15N. The mean annual precipitation (MAP), soil N, and mean annual temperature (MAT) were the most important variables, but the soil water content (SWC), aridity index (AI), and soil clay content were also important variables. The soil pH and soil C: N ratios were identified as unimportant variables. Furthermore, a high-performance model for simulating plant δ15N values was constructed based on the important variables (VIP > 0.8). Further investigations should focus on the effects of the interaction between the climatic and edaphic variables on the N cycles in the temperate grasslands to provide more reliable predictions of plant δ15N.","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45215252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

They are unique in hydrological, edaphic, atmospheric, and biological characteristics, and play important roles in maintaining the ecological security and ecosystem services of coastal zones. Arbuscular mycorrhizae (AM) are symbiont composed of plant roots and arbuscular mycorrhizal fungi (AMF), which are soil-borne microorganisms widely distributed in various habitats. Many previous studies on mycorrhiza have focused on terrestrial ecosystems while few on wetlands, especially coastal wetlands. Method We systematically reviewed previous relevant studies to explore the formation and functions of AM in coastal wetland ecosystems as well as the environmental factors that affect them. Habitat characteristics, morphological types, and species diversity of AMF in the coastal wetlands were summarized. Both responses of AMF to environmental factors during AM formation and the functions of AM in coastal wetlands were discussed. Result AMF are worldwide distributed in coastal wetland and are mainly limited by flooding, hypoxia, soil pH, salinity and the host plants identification. AMF play important roles in coastal wetlands, involving promoting nutrient uptake of host plants, improving the characteristics of rhizospheric soil, and enhancing plant resistance to salt and flooding stress. Conclusion More comprehensive studies of AMF in vitro in coastal wetlands would be helpful for the conservation and restoration of coastal wetland ecosystems in the changing world.","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49641475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The present study compared O3-like VFI registered in the southern European forest sites with actual O3 VFI observed in a FO3X experiment. The O3-like VFIs were evaluated by eye in forests and thus it was subjective. According to the imaging analysis, we firstly demonstrated that major parts of the colors were similar in the field and the FO3X. The color pallets for O3 VFI was species-specific and considered a advanced tool for the O3 VFI diagnosis. In addition, we calculated a flux-based threshold for the O3 VFI onset at the FO3X based on a Phytotoxic Ozone Dose (POD1), which ranged from 4.9 to 18.1 mmol m−2 POD1. This FO3X-derived threshold partly explained but did not necessarily match with the observation for several tree species in actual forests. The multivariate analysis showed that O3 VFI was decreased by the presence of various species and suggested the importance of continuous monitoring activities in the field for the further analysis.","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41346876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This review summarizes the sources and distribution characteristics of MPs in terrestrial ecosystems and explores their effects on soil properties, plant growth, C and N turnover. Once entering the terrestrial ecosystem, MPs could involve in sequestrating carbon and nitrogen by changing soil properties (e.g., pH, soil aggregate stability, and soil porosity). MPs could exert direct influences on plants or on soil physical environment and microbial metabolic environment to indirectly affect plant growth, thus altering the quantity and quality of soil C and N inputs by shifts in plant litter and roots. The changes of the dominant bacteria phyla, related functional genes, and enzymes caused by MP pollution could affect C and N cycles. Additionally, the MP effect varies with its properties (e.g., types, shapes, elemental composition, functional groups, released additives). Future researches should unify the standard system of MP separation, detection, and reveal the ecological effects of MPs, especially their impacts on terrestrial carbon and nitrogen cycles in the context of climate changes.","PeriodicalId":54216,"journal":{"name":"Ecosystem Health and Sustainability","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44860284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

From a scientific research perspective, this paper briefly outlines the divergence between the two disciplines and seeks potential intersections of them. Overall, starting from the practical needs, this paper argues that there are many “plug-in” opportunities that should be explored in the whole research chain to accommodate successful co-development of research in practice, such as sharing similar research interests, jointly identifying research questions and objectives, adopting suitable research methods, well-designed research experiments and parameters (e.g., matched scales, resolution levels, metrics and indicators), co-collection of site-specific data.

The top two food categories contributing to the total CF were meat and grains, accounting for 46.28% and 36.52%, respectively. Furthermore, the location of the university was significantly associated with the CF of plate waste. It also indicated that household income, meal satisfaction, sex, education, meal days, and food-saving campaigns were important factors influencing the CF of food waste.
