We evaluated the impact of lawns and meadows across agricultural, residential, and industrial landscapes in structuring bees, wasps, and flower flies communities. We carried out plant and insect inventories on 18 lawns and 18 meadows distributed evenly among agricultural, residential, and industrial landscapes within the Greater Quebec City region (Quebec, Canada). Insect sampling was conducted five times using bowl traps and entomological nets, from June to September 2020. Results indicate taxon-specific responses to landscape matrix and site maintenance. Agricultural landscapes negatively influenced bee abundance compared to urban areas, while the opposite trend was observed for flower flies. Wasp abundance and richness were negatively influenced by both agricultural and industrial matrices compared to residential landscapes. Regarding site maintenance, bees and wasps were 3 and 12 times more abundant and 2 and 6 times more species-rich, respectively, in meadows than in lawns as per the data aggregated across the sampling date. Flower fly abundance was higher in meadows than in lawns for agricultural and residential landscapes only, while richness was consistently higher (2 times greater) in meadows compared to lawns. Some species of the sweat bee genus <i>Lasioglossum</i> and the flower fly margined calligrapher (<i>Toxomerus marginatus</i>) were dominant in lawns, while meadows hosted a more balanced community among genera and supported pollinators with wide-ranging resource requirements. Our results suggest that conservation actions should consider both landscape and local management to conserve central-place foragers, such as bees and wasps, and for structuring flower fly species composition.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"11 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140002291","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}

Urban birds are typically resident non-forest species with a broad diet and nesting high in trees or in cavities, and some studies have also claimed that they are large-brained. However, little is known about how urban bird communities change over time. Does the urban environment impose specific selective pressures favouring particular species or ecological groups, or do birds in urban areas simply have population changes reflecting population trends at larger scales? We assessed population changes of 45 breeding land bird species in Oslo, the capital of Norway, based on surveys conducted ca. 15 years apart. Population changes within Oslo most closely matched changes occurring at the regional level (national population trends from Norway and Sweden). Thus, species increasing in Oslo were those that also increased at the regional level. We found no evidence that relative brain size, diet or habitat preferences influenced population trends. However, controlling for regional population trends, there were additional residual effects of nest site and migration: species nesting on the ground or low in bushes had more positive changes than species nesting high in trees or in cavities, and resident species did better than long- or short-distance migrants.

We identified the two key action areas “civic participation” and “cooperative area activation” covering ten key transition activities to illustrate the variety and content of a transformation towards an edible city. Based on expert interviews and document analyses, we evaluated their process progression by linking research from urban ecology with transformation science. By visualizing its quantitative results, common and distinct patterns of the edible city initiatives could be made visible. Overall, we found that the level of activity is highest in the key action area of “citizen participation”. In this context, both transition experiments had different but specific foci in terms of their key transition activities (i.e. education, activation of stakeholders), whereby activities related to civic empowerment and social cohesion were lacking in both cases. To re-shape narratives pertaining to land access, food production, and participation under the principles of justice, we suggest that transition experiments related to “civic participation” and “cooperative area activation” must be approached together. Our systematic assessment can then enable civic transition teams to strategically identify common goals that need to be prioritized for initiating, innovating, and accelerating urban edible commons.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"33 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139967885","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}

We used species distribution modelling to assess urban ecological niche of wild boars and to identify landscape features that they select or avoid. We created a database based on field surveys carried out on a sample of grid cells where evidence of boar presence was recorded. We used logistic regression models to predict wild boar presence in the study area. Our results showed that the probability of boar presence was driven by access to resources and modulated by avoidance of densely built-up areas. In contrast, urban boars appeared to be indifferent to habitat fragmentation and secondary roads. Finally, a large part of the urbanistic urban green frame of Bordeaux was likely to support wild boar. These results provide a first picture of the situation, but must be considered as a first stage of investigations on the spatial ecology of urban boars. They also need to be placed in a broader socio-ecological context. From a life science perspective, urban wild boars provide an excellent example of urban wildlife adaptation. However, human-wildlife coexistence also raises planning, management, socio-cultural and ethical issues. We argue that objectifying wildlife use of urban space is a prerequisite to implement meaningful management measures.

These water-limited conditions may be exacerbated by the projected increases in drought events caused by climate change. As a result, plants that grow in urban areas are vulnerable to drought stress. There are a range of practices that can be used to help mitigate drought stress, including the use of biostimulants. This study aimed to determine whether biostimulant application (1) improves plant performance and (2) mitigates the drought stress on urban plant species. To address these aims, we selected six woody and three graminoid plant species that are commonly planted in Australian urban areas and exposed them to different watering (drought-stressed, well-watered) and biostimulant (control, humic acid, protein hydrolysate, seaweed extract) treatments. We then measured their assimilation rate, growth metrics and biomass allocation. We found that drought stress reduced the assimilation rates and shoot growth of the study species. However, this did not translate into a biomass reduction because the drought-stressed plants reallocated resources towards root biomass. We found no evidence to suggest biostimulant application mitigated the impacts of drought stress on plant performance. Further, the only effect biostimulant application had on plant performance irrespective of the watering treatment was that the seaweed biostimulant increased the plant height growth of the woody species. These results show that the biostimulants used in this study will have a limited effect on the performance of plant species commonly planted in Australian urban areas.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"15 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139758310","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}
