To do so, however, it is important to know what types of environmental features impact how connected to nature certain environments make us feel. The present study used a novel application of network analysis to identify which environmental features are most important for nature connection experiences. In this research, 205 participants completed online surveys in which they reported the presence or absence of a variety of environmental features during four previous nature connection experiences. They also indicated their level of recalled nature connectedness for each experience. The network analysis revealed that the most positively important features were those commonly found in rural nature (e.g., wild nature, animals, and mountains or hills). Features reflecting human presence (e.g., buildings, paved roads, vehicles) were most negatively important. Features commonly found in semi-rural nature (e.g., trees and meadows) were seemingly only important insofar as they were associated with the wilder features. Additionally, trails, wild nature, and mountains or hills were three of the features most central to nature connection experiences, suggesting that they are particularly important for how they support other parts of the network. Overall, from a purely nature-connection perspective, these findings support the need for increased rewilding efforts—more than simply increasing basic access to urban nature—and also limiting the overt presence of human development. Other more nuanced findings are also discussed.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"259 ","pages":"Article 105362"},"PeriodicalIF":7.9,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Although human activities can decrease biodiversity, humans can also provide resources, which can potentially increase species richness. However, it is largely unknown how seasonal community characteristics vary in relation to the characteristics of both the landscape and species. For this study, we evaluated how landscape characteristics and species traits influenced habitat use (i.e., patch occupancy, persistence, and colonization) and species richness across seasons and a gradient of urbanization, hypothesizing that habitat use and richness would increase with patch diversity and seasonally dynamic vegetation productivity but decrease with urbanization. We further predicted that use and richness would vary seasonally and increase in areas of urbanization during the summer season. Across the Phoenix Metropolitan Area, Arizona, we used 50 wildlife cameras to evaluate the wildlife community for one year (2019–2020). We estimated seasonal habitat use and richness of this wildlife community across the spring, summer, and winter seasons using multi-scale community occupancy models. As predicted, seasonal use and richness consistently demonstrated negative relationships with urbanization. Contrary to predictions, use and richness did not increase in urbanized areas during the summer season. However, habitat use further varied according to species traits, with larger-bodied species exhibiting higher site use in less urbanized landscapes. Overall, similarities in species richness across seasons and low colonization rates suggest that habitat quality and/or spatial barriers may restrict the ability of wildlife to use fragmented and urbanized landscapes. Limiting urbanization within currently wildland areas and enhancing spatial connectivity could improve the ability of wildlife communities to utilize temporally dynamic resources and persist across anthropogenic landscapes.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"259 ","pages":"Article 105346"},"PeriodicalIF":7.9,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143677896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 study utilizes latent growth models and random intercept cross-lagged models for longitudinal analysis. The study revealed that between 2014 and 2020, the physical function of rural older adults exhibited gradual improvement. However, mental health issues have become increasingly prevalent, particularly among the older aged group. Furthermore, air pollution significantly negatively affects both the physical and mental health of rural older adults, with the impact being most pronounced in the older aged group. Conversely, green spaces positively influence the mental health of rural older adults, although this benefit is significant only among the younger aged group. Moreover, the study identifies interaction effects between air pollution and green spaces regarding the health of older adults. Green spaces effectively mitigate the adverse effects of elevated air pollution on physical health of the older aged group, while air pollution diminishes the positive effects of limited green spaces on mental health of the younger aged group. Therefore, it is crucial to consider these age group differences when formulating environmental intervention strategies aimed at enhancing the health of older adults.

We analyzed 6105 specimens across 91 sites, including protected areas, in the industrial belt of Hainaut, Belgium. We compared the effects of land cover components and site protection for several definitions of conservation value, including diversity indices and the number of threatened species. We found that urbanization increased diversity when abundance-based indices were examined, while simultaneously reducing the richness of threatened species. Flower-rich grasslands did not improve diversity indices, but they increased the number of threatened species. Forested areas were negatively associated with all diversity metrics except the number of threatened species. Similarly, protected areas displayed lower indices of diversity, but not fewer threatened species. This pattern aligns with the predominance of forested areas around protected sites. Our results suggest that the decline of threatened species in urban environments may be masked by high diversity among abundant species, a pattern detectable only through multiple metrics of conservation value. In addition, we reveal that existing networks of protected areas in the landscape may not be able to mitigate this decline, as reserves are not necessarily designed for the conservation of all species and may be biased towards certain types of environments.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"259 ","pages":"Article 105347"},"PeriodicalIF":7.9,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, how to enhance its cooling effect through optimized spatial patterns (e.g., city-level structure and network) has received little concern. Based on 310 Chinese cities, this study explored the multi-dimensional features of UGI and their interactive and conjoint impacts on surface UHI (SUHI) to identify the optimized cooling pathways under specific climatic backgrounds. In particular, the patterns of UGI were characterized by eight dimensions, i.e., quantity, patch size, shape complexity, fragmentation, contiguity, diversity, structure, and connectivity, each using one representative metric. Then the complex pathways of how UGI affected SUHI were investigated using the structural equation model, with the potential moderating role of climatic backgrounds taken into consideration. Results revealed that UGI affected SUHI through diverse pathways, and each pathway covered discrepant UGI features with various influencing directions and magnitudes. Among all pathways, direct impacts surpassed indirect ones, whose performances were largely diminished by multiple complex and counteracting mediation effects. Coverage, contiguity, structure, and connectivity, with the latter two dimensions largely neglected by previous studies, were found to be the primary cooling features. Among them, connectivity, despite its dominated impact in direct pathways, remained at low levels due to limited consideration and poor execution in previous planning practices. Typically, with the same UGI coverage, cities equipped with more clustered structure and connected network exhibited relatively lower SUHI intensity. For most cities, such enhanced cooling benefits can be achieved through mediation effects by smaller patches, more complex shapes, and shorter inter-patch distances. For cities in tropical and subtropical regions facing severer heat issues, however, it is recommended to optimize UGI design by adopting simple and regular patches with scattered distribution. This study extended the understanding of how to configure UGI for enhanced cooling effects from local to city level. The results may benefit urban planners pursuing climate resilient cities.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"259 ","pages":"Article 105344"},"PeriodicalIF":7.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
