The Spring River in southeastern Kansas historically received inputs of cadmium, copper, lead, and zinc that reduced the prevalence of several sensitive and imperiled fishes. Long-term reductions in these toxic metals have occurred since the 1990’s because of management activities, but presently it is unknown how riffle fish communities responded to improved water quality. As such, the objective of our research was to quantify changes in riffle fish community structure between 1993–1995 and 2019–2021 using a before-after-control-impact (BACI) study design. Responses were quantified with univariate analyses to examine the interactive effects of time period (i.e., historical versus contemporary), pollution tolerance classification (i.e., intolerant, moderately-intolerant, moderately-tolerant, and tolerant), and site position (i.e., above versus below the most severe historical metal pollution inputs) on relative abundance, occupancy, and species richness of riffle fishes. We used multivariate analyses to examine temporal changes in community structure above and below pollution inputs. Our findings indicated that intolerant fish species relative abundance increased between the historical and contemporary time periods throughout the Spring River. Occupancy of all fishes increased over time in the formerly metal contaminated portion of the Spring River, becoming similar to values in the reference reach. Changes in species richness depended on site position and pollution tolerance, as temporal increases of intolerant and moderately intolerant species richness were most pronounced in the lower Spring River below historical metal pollution inputs. Multivariate analyses revealed a significant interaction between time period and site position, as there was a shift in community structure over time in the lower reach that was less pronounced in the upper reach. Most of the intolerant species that increased in prevalence are of high conservation priority, thus our research suggested that legislation enacted to improve water quality produced a ripple effect that stimulated the recovery of imperiled fish species.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"75 2","pages":"240 - 255"},"PeriodicalIF":2.7,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142692492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Over the past century, numerous fish-based indices have been developed to estimate the abstract property of stream health. The Index of Biotic Integrity (IBI) is the predominant technique used by state and federal agencies in the United States and has been widely used by these agencies following its inception over 40 years ago. However, biogeographic patterns can often confound the application of traditional IBI frameworks in highly speciose regions. While nearly all regional IBI versions are developed to suit particular geographic regions, few measure contemporary biogeographic changes (such as loss or maintenance of endemic species) even though these properties are critical components of “healthy” ecosystems in highly diverse regions. Quantitative analyses from recent decades have shown that the proportion of endemic fishes may decline, but that other taxonomically and ecologically similar widespread (albeit native) species may replace them. Herein, we summarize challenges using traditional trait-based fish IBIs in the southeastern United States—a region with unparalleled fish species richness and endemism within the temperate world. In our experience, complex biogeographic patterns and scant biological information for many fish species in this region often hinder the ability of traditional fish-based biotic integrity indices to measure stream health. Tailoring indices and metrics to better suit biogeographic patterns and incorporating traits such as species identity and endemism may help to further refine stream health indices in highly diverse regions.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"75 2","pages":"167 - 174"},"PeriodicalIF":2.7,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142692489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 design and implementation of REDD+ projects in many developing countries, including Ghana, have faced complex governance challenges. In recent years, a collaborative governance approach has been increasingly recommended for effective REDD+ implementation, but the impact of the dynamics of developing countries' context on collaboration success remains unclear. Using Ghana's Cocoa Forest REDD+ Programme (GCFRP) as a case study, this paper aims to increase our understanding of how the dynamics of developing countries' context affect the drivers shaping the initiation of REDD+ collaborative regimes for transforming cocoa forest landscapes. Through qualitative content analysis of document reviews and semi-structured interviews with national program stakeholder groups, the results indicate that Ghana's dynamic context facilitates collaboration on REDD+ implementation when stakeholders feel uncertain about the future availability of forest resources and recognize their interdependence in responding to such issues. Additionally, the findings of the study indicate that strong political will for change, along with strategic windows of opportunity created by REDD+ funding mechanisms, play a vital role in shaping consequential incentives essential for aligning stakeholder interests and fostering cross-sector leadership for initiating the REDD+ collaborative governance regime. While the applicability and limitations of the IFCG framework are discussed, further in-depth studies at project levels are crucial to understanding local stakeholders' perspectives on the key elements necessary for successful collaboration.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142685721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Over the past 50 years, riparian vegetation has been returning, unassisted, to rivers in eastern Australia that have been experiencing geomorphic river recovery. We used a novel rapid riparian assessment method to analyse vegetation condition on rivers undergoing geomorphic recovery. The rapid riparian assessment method incorporated vegetation cover, native species richness, the proportion of native to exotic species cover, and other features of vegetation health to produce a vegetation condition score that classifies sites as poor, moderate, or good. Vegetation condition was analysed along 36 river reaches in coastal catchments of New South Wales (NSW) in three different climatic regions (North, Mid and South coasts), covering three stages of geomorphic recovery (low, moderate and high) and for three geomorphic units (bars, benches and floodplains). Most reaches had a poor or moderate riparian vegetation condition, with only three sites assessed as being in good condition. Native species richness and proportion of native to exotic species cover were higher in the later stages of geomorphic recovery and on benches and floodplains, compared to bars. However, most of the riparian vegetation on recovering rivers consisted of a mixture of native and exotic species, highlighting that even in the later stages of recovery, novel communities are produced that do not resemble the pre-disturbance ecosystem. To improve vegetation quality at-scale (i.e. across catchments and regions) will require that vegetation management interventions are designed and adapted to work with these novel ecosystems, and that realistic rehabilitation targets and expectations are set to account for the geomorphic and vegetative recovery that is occurring along these rivers.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"75 2","pages":"221 - 239"},"PeriodicalIF":2.7,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142685720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Accurate and effective evaluation techniques are essential for identifying regions that are of ecological relevance and concern. The present research introduces an innovative approach using geospatial tools to detect natural hotspots and deficits within a landscape. The research incorporates six essential ecological parameters, namely spatial variability, vegetation health, road network connectivity, fragmentation, biological richness, and habitat areas, obtained from existing literature studies. These parameters indicate the overall health of ecosystems and the extent of biodiversity present, which are crucial for developing effective strategies for ecological planning. The research project aims to use geospatial applications to identify the \"ecological rich\", \"ecological moderate\" or \"ecological deficit\" areas in the study area and to establish a model framework for automating the geospatial analysis. The resulting map offers a comprehensive and practical depiction of the ecological condition of the landscape, facilitating decision-makers in strategically allocating resources for conservation and restoration initiatives. The importance of this research resides in its capacity to streamline and automate what was previously a time-consuming and labor-intensive procedure.

Understanding the motivation crowding effect in the context of pro-environmental behavior of farmers is crucial for formulating agricultural environmental policies. However, there is limited knowledge about the motivation crowding effect on farmers' land quality protection behavior, especially in developing countries. This study employs stratified regression models, propensity score matching models, seemingly unrelated regression models, and simple slope analysis methods to analyze the impact of extrinsic motivations (external incentives such as increasing farming income and production yield) and intrinsic motivations (internal drives such as personal satisfaction and responsibility) on farmers' land quality protection behavior, as well as the motivation crowding effect between extrinsic and intrinsic motivations. The analysis is based on survey data from 1064 smallholder farmers in five provinces in China: Zhejiang, Jiangsu, Henan, Shaanxi, and Gansu. The results indicate that both extrinsic and intrinsic motivations have a positive impact on farmers' land quality protection behavior. Notably, extrinsic motivation exhibits a crowding-out effect on intrinsic motivation, suggesting a motivation crowding effect. While promoting farmers' land quality protection behavior through economic incentives is a feasible short-term solution, it may not effectively foster the long-term formation of such behaviors. Given the current context of severe land pollution, alleviating this issue through economic incentives represents a short-term policy approach. Thus, transitioning from short-term to long-term solutions by enhancing farmers' intrinsic motivation to promote farmers' land quality protection behavior is essential for the government to consider in future land protection policy formulation.</p>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142643501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

A supplementary feeding experiment was conducted at Grootbos Private Nature Reserve in South Africa, using sugar-water feeders when floral abundance was low (winter) and high (spring). We compared bird abundance and visitation rates to flowers before, during, and after feeder presence in both seasons. The use of sugar-water feeders by nectarivorous birds was inversely related to floral abundance, with 679 bird visits (6.94 ± 1.40 bird visitation rate per hour) to feeders in winter and only 90 visits (0.41 ± 0.16 visitation rate per hour) during spring. Bird visits were higher at flowers than at sugar-water feeders, in both seasons. Sugar-water feeders did not influence the visitation rate of sunbirds to flowers in both seasons, contrasting with findings from areas abutting suburbia, suggesting that feeder influence on bird visitation rate may not be apparent in areas with no history of sugar-water feeders.
