Characteristics of the urban sewer system and rat presence in Seattle
27. Juni 2022
Abstract Rats are abundant and ubiquitous in urban environments. There has been increasing attention to the need for evidence-based, integrated rat management and surveillance approaches because rats can compromise public health and impose economic costs. Yet there are few studies that characterize rat distributions in sewers and there are no studies that incorporate the complexity of sewer networks that encompass multiple sewer lines, all comprised of their own unique characteristics. To address this knowledge gap, this study identifies sewer characteristics that are...
Urbanites’ perception of vegetation in landscape-based stormwater management elements (LSM)
27. Juni 2022
Abstract The popularity and use of green infrastructure measures such as green roofs, green walls, and curb extensions is growing, especially in dense urban areas. At the same time, from an ecosystem services perspective, interest in urban nature and reconciliation ecology is underlined. Attempts to introduce more biodiverse vegetation in cities can conflict with the responses of some urbanites to the appearance of “wild” vegetation. Through semi-structured interviews with 47 randomly picked bypassers in Copenhagen, Denmark, this study explored urbanites...

Urbanisation and land-cover change affect functional, but not compositional turnover of bird communities
22. Juni 2022
Abstract Land-use and land-cover change strongly affect biodiversity patterns and are assumed to be growing threats in the future. Particularly increasing urbanisation may affect species turnover and functional composition of biological communities. This study aimed to assess the characteristics of land-cover change in a medium-sized urban municipality from 2011 to 2018, and the effects of urbanisation on avian species- and functional diversity. The study was performed in Trondheim (Norway), using local land-cover maps and GBIF bird species occurrence records. GLMMs were...
Callout analysis in relation to wild birds in a tropical city: implications for urban species management
21. Juni 2022
Abstract Urbanisation is changing landscapes at an unprecedented rate, which consequently changes species compositions. We investigate problems faced by urban birds in a neotropical city by analysing the responses made to callouts by the environmental police of Belo Horizonte, Minas Gerais, Brazil from 2002 to 2008. The environment police responded to two types of callouts: solicitation, where a person called to report an issue (n = 560); and reports of hurt or injured birds (n = 399). On average, three callouts per week were made relating to urban birds, with...
Plant performance analysis of biofacades in a hot, arid Region of Qatar
21. Juni 2022
Abstract Green walls are a traditional system that has been rediscovered for addressing and combating effects of climate change on the urban environment. The greening of walls is one of the sustainable techniques towards green architecture, and it has become a significant part of the passive design. This research employed an integrated approach to create healthy urban spaces and improve people’s overall quality of life through introducing the concept of biofacades to make a city more sustainable. Today, accelerated growth in urban development is occurring in Doha, the...
Human-wildlife interactions: presence of the ground-nesting Spotted Thick-knee across a South African mosaic urban landscape
20. Juni 2022
Abstract Urbanisation has increasingly encroached on numerous bird species' natural habitats, generally negatively affecting their persistence. Furthermore, increased human-wildlife interactions may benefit or be detrimental to the long term persistence of these species. The Spotted Thick-knee (Burhinus capensis), a ground-nesting species, persists in some mosaic urban landscapes in South Africa. We, therefore, assessed the presence of Spotted Thick-knees and their interactions with humans in the fragmented natural and human-modified landscape of Pietermaritzburg...
Effect of urbanization on the dynamics of ecosystem services: An analysis for decision making in Kolkata urban agglomeration
18. Juni 2022
Abstract Urbanization has profound influence on the changes of land use and land cover, which on the other hand exert significant impact on ecosystem services and their values, especially in the urban agglomerations. Kolkata urban agglomeration of India has been selected to determine the causes in changes of ecosystem services under present and projected land use land cover scenario. Land use land cover maps of 1990, 2000, 2010 and 2020 were prepared by support vector machine method, using LANDSAT satellite imageries and projected up-to 2040 using CA–Markov model...
Using crushed waste bricks for urban greening with contrasting grassland mixtures: no negative effects of brick-augmented substrates varying in soil type, moisture and acid pre-treatment
16. Juni 2022
Abstract Ecological restoration aims at supporting biodiversity and ecosystem services, and urban greening is a great opportunity to achieve this goal. This is facilitated by species-rich seed mixtures based on local provenances, which are designed for certain nutrient and moisture regimes based on functional plant traits. Such grassland mixtures might be cultivated on crushed waste bricks, which would be a new component of water-holding urban substrates. Thus, we studied the effects of brick quantity and quality, acid pre-treatment of bricks, soil type and moisture on...

Aquatic biodiversity loss in Andean urban streams
14. Juni 2022
Abstract Andean rivers support an amazing biodiversity and provide important environmental services for Andean landscapes like water for agriculture and human consumption. Urban areas in Andean countries have grown at an accelerated rate in the last decades. As a consequence, a lack of wastewater treatment and riparian preservation have threatened these streams. We studied urban, agricultural, and well-preserved streams in the Upper Guayllabamba River Basin, where Quito, the capital city of Ecuador, is located. We found an aquatic insect richness loss of 78% in urban...
Predictors of tree cover in residential open space: a multi-scale analysis of suburban Philadelphia
13. Juni 2022
Abstract Tree cover is an important aspect of environmental quality and quality of life, but is declining in many metropolitan regions. This study examines tree cover and its relationship with scale in a type of suburban green space that is common in the United States, residential open space. A variety of urban and residential tree cover studies exist, but none examine the factors that explain the tree cover in these small open spaces, which have the potential to support significant conservation value in developed and developing areas. This study uses remote sensing, GIS...
Morphological stability of rural populations supports their use as controls in urban ecology studies
08. Juni 2022
Abstract The expansion of urban environments and how animals may be affected by them are being increasingly investigated, leading to a surge in urban ecology studies. Many urban ecology studies involve a direct comparison between rural and urban populations, or the use of urban gradients along a continuum from rural to urban areas. The implicit, although not properly investigated, assumption in these rural vs urban comparisons is that the rural populations offer a control that represents a lack of the anthropogenic stressors affecting the urban populations. Here we used...

The urban myth: A lack of agreement between definitions of urban environments used in wildlife health research may contribute to inconsistent epidemiological findings
01. Juni 2022
Abstract Worldwide, urbanization and associated anthropogenic land use change is increasing. This has implications for the ecology of wildlife diseases including zoonoses, and relevance for wildlife management, urban planning, and public health. Therefore, wildlife health in ‘urban’ environments is an increasing focus within the published literature. However, researchers use a variety of different classification strategies since there is no established definition of an ‘urban’ environment. It is unclear the degree to which different interpretations of the term...
Citizen science in cities: an overview of projects focused on urban Australia
01. Juni 2022
Abstract Citizen science offers a unique opportunity to connect urban-dwellers with the often hidden natural world upon their doorsteps and to contribute to authentic research that increases knowledge of urban ecology and biodiversity. With the majority of Australia’s population residing in large cities, this diverse potential pool of participants in science creates a significant opportunity to increase the spatial and temporal scale of research. Herein, we provide an overview of Australian urban citizen science projects based on an analysis of the projects listed in...
Noise attenuation varies by interactions of land cover and season in an urban/peri-urban landscape
01. Juni 2022
Abstract Anthropogenic noise is increasing worldwide because of growing human populations, transportation, and resource extraction. This excessive noise negatively impacts humans and wildlife. To mitigate noise pollution, the use of vegetation in urban planning is becoming increasingly common. However, noise attenuation can be influenced by poorly understood differences in land cover and seasonality that exist across complex urban and peri-urban environments. We compared the noise attenuation capacity of sites typifying dominant land covers in southern Ontario, Canada...
Long-term assessment of floodplain reconnection as a stream restoration approach for managing nitrogen in ground and surface waters
01. Juni 2022
Abstract Stream restoration is a popular approach for managing nitrogen (N) in degraded, flashy urban streams. Here, we investigated the long-term effects of stream restoration involving floodplain reconnection on riparian and in-stream N transport and transformation in an urban stream in the Chesapeake Bay watershed. We examined relationships between hydrology, chemistry, and biology using a Before/After-Control/Impact (BACI) study design to determine how hydrologic flashiness, nitrate (NO3−) concentrations (mg/L), and N flux, both NO3− and total N (kg/yr), changed...
Tree trade-offs in stream restoration: impacts on riparian groundwater quality
01. Juni 2022
Abstract Riparian zones are a vital interface between land and stream and are often the focus of stream restoration efforts to reduce nutrient pollution in waterways. Restoration of degraded stream channels often requires the removal of mature trees during major physical alteration of the riparian zone to reshape streambank topography. We assessed the impact of tree removal on riparian groundwater quality over space and time. Twenty-nine wells were installed across 5 sites in watersheds of the Washington D.C. and Baltimore, Maryland, USA metropolitan areas. Study sites...
