In this perspective piece, to demonstrate the utility of acoustic telemetry to assess ecological restoration in aquatic systems, we synthesize two case studies in coastal freshwater and marine urban ecosystems: Toronto, Canada, and Bergen, Norway. In Toronto Harbour, a Before-After-Control-Impact experimental design was instrumental in detecting differences attributed to ecological restoration across multiple species of fish. Additionally, acoustic telemetry data were paired with catch and community traits derived from electrofishing, which provided a more complete understanding of fish responses to restoration. In Bergen Harbour, the acoustic telemetry array was deployed before restoration, providing a Before-After comparison of habitat use by several fish species and European lobster (<i>Homarus gammarus</i>). In addition to acoustic telemetry, blood samples were taken from multiple fishes, to examine the levels of contaminants before and after restoration, adding an ecotoxicological dimension to the assessment. Incorporating these complementary methods contributed to a more holistic understanding of animal response to ecological restoration. Finally, we also identified indicators that could be calculated using acoustic telemetry data, including those derived from addition sensors (e.g., pressure). As we look to the future within the Anthropocene, it will be imperative that ecological restoration achieves intended goals and we contend that acoustic telemetry has a bigger role to play in the evaluation of efficacy as it provides continuous monitoring compared to more traditional, discrete sampling.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"167 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141740342","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}

Urbanization may alter not just the distributions of individual species, but also co-occurrence patterns and thus the potential for interspecific interactions (e.g., competition, predation) that structure wildlife communities. Little is currently known about how urbanization alters species co-occurrence or how these changes shape urban species assemblages. Using tree squirrels as a model functional group, we quantified how urbanization alters species occurrence and co-occurrence patterns to shape species assemblages, and how these effects vary within and among cities. We constructed a multi-species, multi-season occupancy model to identify relationships between tree squirrel occupancy and co-occurrence and local land and tree canopy cover and examined variation in these relationships within and among nine US cities. Species’ responses to canopy cover were highly variable among, but less variable within cities, suggesting that even common urban wildlife species may respond differently to urban intensity in different landscape contexts. Species co-occurrence was also highly variable among cities and weakly related to canopy cover within a city. These findings provide important evidence that both environmental attributes and species interactions shape urban wildlife communities. Important for management and conservation, they suggest that tree-canopy cover can particularly support forest species co-occurrence and that managing urban forests to provide high canopy cover could contribute to the diversity of urban wildlife communities in forested ecoregions.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"14 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141740341","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}

Understanding how wildlife interacts with humans and the built environment is critical as urbanization contributes to habitat change and fragmentation globally. The environmental drivers that influence HWIs are largely unknown in some systems, however, especially across multiple spatial scales. Using location and species data from a business that relocates snakes across the Phoenix metropolitan area (Arizona, USA), we found the most frequently removed were venomous (family Viperidae, e.g., rattlesnakes). Nonvenomous snakes were also removed (family Colubridae, e.g., gophersnakes). Using these records, we investigated taxa-specific habitat relationships at two spatial scales. The neighborhood scale focused on front yard measures of cover and vegetation classes, and the landscape scale focused on remote-sensed variables related to vegetation indices and degree of urbanization. Both analyses compared areas where snakes were removed to random locations in the city to evaluate used and available locations of snakes. At the neighborhood scale, snake removals (<i>n</i> = 59) occurred in yards with abundant vegetation and debris cover opportunities compared to random locations. At the landscape scale, snake removal locations (<i>n</i> = 764) had taxa-specific differences, with nonvenomous snakes removed from areas of higher urbanization than venomous snakes, a pattern was likely related to differences in life history and behavior. Environmental variables associated with HWI can vary across different spatial scales.

These interactions can be either positive, such as providing ecosystem services, or negative, resulting in human-wildlife conflicts. Despite growing literature on these interactions, a comprehensive review focusing on urban environments has been lacking. This study aimed to address this gap by conducting a systematic review using Google Scholar and the Scopus bibliographic database. A total of 45 studies met the search criteria, with a predominant prevalence of the northern hemisphere. Accipitriformes was the most studied order of raptors (50%), followed by Strigiformes (37%), Falconiformes (8%), and Cathartiformes (2%). Positive interactions studied included cultural services, pest control, positive perception, carrion removal, while negative interactions involved safety damage, property damage, negative perception, disease transmission, livestock damage, nuisance and superstitions. Pest control and cultural services were supported by the evidence, although only for specific orders. Carrion removal and aggressiveness appear to decrease with urbanization, although more studies are needed to verify this premise. Both positive and negative perceptions were evident, influenced in part by the knowledge or closeness that people had towards urban raptors. We discuss how the interactions studied influence the daily lives of citizens and, in turn, how human activities shape and influence these interactions. Finally, given that cities are socio-ecological systems, we advocate for methodologies that integrate the social aspects of human-predator interactions along with ecological ones to promote coexistence.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"33 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141717497","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}

While waterfowl species have generally increased in abundance due to investments in habitat restoration and species management, most other waterbird species have declined. In contrast to the widespread decline of natural habitat for waterbirds, urban greenspaces have proliferated. However, the extent to which urban greenspaces provide habitat for waterbirds is largely unknown. We measured waterbird abundance in Forest Park, Saint Louis, which contains a large expanse of restored waterways. Between 2020 and 2022, we used point counts to quantify alpha and beta diversity of waterbirds across five waterbodies. We also quantified several environmental factors hypothesized to influence waterbird presence including weather, bathymetry, water quality, and prey abundance. We assessed environmental drivers of alpha and gamma diversity using generalized linear mixed models, and beta diversity with Jaccard’s similarity indices and Mantel tests. Water depth and depth heterogeneity were the strongest determinants of alpha diversity. Measured environmental variables did not predict beta diversity but improved model fit when testing gamma diversity. Forest Park is a regionally important urban habitat for waterbirds, hosting 62% (38 species) of the total regional species pool, including nine species of conservation concern and two state endangered species. Urban parks can contribute to waterbird conservation despite habitat loss elsewhere if park managers prioritize habitat restoration. In addition to the total area of waterways, water depth and water depth homogeneity are important considerations to maximize waterbird species diversity in urban greenspaces.</p>","PeriodicalId":48869,"journal":{"name":"Urban Ecosystems","volume":"6 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141550395","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 collected data on bird species richness residing in 44 greenspaces and quantified abiotic, biotic and dispersal attributes of each site. These attributes include size, degree of urbanization within and around the greenspace, vegetation cover, distance between sampled greenspaces, distance to nearby greenspace, distance to the closest natural vegetation patch, distance to city center and distance to periphery of the city. We used Generalized Linear Models to determine the effect of spatial characteristics of urban greenspaces on bird species richness. We then built matrices of beta diversity between greenspaces and assessed bird taxonomic dissimilarity via multivariate Bray-Curtis cluster analysis. Our results showed that bird species richness varies between greenspaces. However, species richness was not correlated with spatial characteristics or biotic attributes (<i>P</i> &gt; 0.05), and we only found marginal correlations between built cover within the greenspace and richness of resident species (<i>P</i> = 0.065) and waterbird species (<i>P</i> = 0.070).

This effect is particularly acute in urban and periurban areas, where the area of effective disturbance extends beyond that of human presence by the roaming behaviour of pet dogs.

In southeast and southern England these areas include lowland heath, a habitat of high conservation value. To quantify disturbance caused by dog walkers and their dogs, we used GPS units to track the movement of people and their dogs across four lowland heath sites, used a questionnaire to ask about dog walking habits, and mapped potential areas of disturbance caused by dog walkers. Questionnaires were completed by 798 dog walkers and the walks of 162 owners and their 185 dogs were recorded.
