How do urban green space designs shape avian communities? Testing the area–hete...
Chiron, François; Lorrillière, Romain; Bessa-Gomes, Carmen; Tryjanowski, Piotr; Casanelles-Abella, Joan; Laanisto, Lauri; Leal, Ana I.In cities, green areas are essential for biodiversity conservation, with land cover heterogeneity being a decisive factor. Yet, as heterogeneity increases for a given green area, the patch size of land covers automatically decreases, as the area available for individual species, especially habitat specialist species. This relationship, known as the area-heterogeneity trade-off, is expected to lead to a unimodal...
The magnetic signal from trunk bark of urban trees catches the variation in par...
Van Mensel, Anskje; Wuyts, Karen; Pinho, Pedro; Muyshondt, Babette; Aleixo, Cristiana; Orti, Marta Alos; Casanelles-Abella, Joan; Chiron, FrançoisBiomagnetic monitoring increasingly is applied to assess particulate matter (PM) concentrations, mainly using plant leaves sampled in small geographical area and from a limited number of species. Here, the potential of magnetic analysis of urban tree trunk bark to discriminate between PM exposure levels was evaluated and bark magnetic variation was investigated at different spatial scales. Trunk bark was sample...
Negative relationship between woody species density and size of urban green spa...
Alós Ortí, Marta; Casanelles-Abella, Joan; Chiron, François; Deguines, Nicolas; Hallikma, Tiit; Jaksi, Piia; Kwiatkowska, Patrycja K.; Moretti, MarcoUrban green spaces (UGSs) are important elements of urban landscapes. Woody vegetation is a key component of UGSs, providing many socio-ecological benefits such as habitat provision and human well-being. Knowing plant diversity and vegetation configuration that underpin urban ecosystem processes and functions is critical to maximize nature contributions to city dwellers. Here, we present a well-replicated multi...
Modelling the response of urban lichens to broad-scale changes in air pollution...
Rocha, Bernardo; Matos, Paula; Giordani, Paolo; Piret, Lõhmus; Branquinho, Cristina; Casanelles-Abella, Joan; Aleixo, Cristiana; Deguines, NicolasTo create more resilient cities, it is important that we understand the effects of the global change drivers in cities. Biodiversity-based ecological indicators (EIs) can be used for this, as biodiversity is the basis of ecosystem structure, composition, and function. In previous studies, lichens have been used as EIs to monitor the effects of global change drivers in an urban context, but only in single-city s...
Phyllosphere bacterial communities in urban green areas throughout Europe relat...
Muyshondt, Babette; Wuyts, Karen; Van Mensel, Anskje; Smets, Wenke; Lebeer, Sarah; Aleixo, Cristiana; Alós Ortí, Marta; Casanelles-Abella, JoanThe phyllosphere harbours a diverse and specific bacterial community, which influences plant health and ecosystem functioning. In this study, we investigated the impact of urban green areas connectivity and size on the composition and diversity of phyllosphere bacterial communities. Hereto, we evaluated the diversity and composition of phyllosphere bacterial communities of 233 Platanus x acerifolia and Acer pse...

A dataset of the flowering plants (Angiospermae) in urban green areas in five E...
Casanelles-Abella, Joan; Frey, David; Müller, Stefanie; Aleixo, Cristiana; Alós Ortí, Marta; Deguines, Nicolas; Hallikma, Tiit; Laanisto, LauriThis article summarizes the data of a survey of flowering plants in 80 sites in five European cities and urban agglomerations (Antwerp, Belgium; greater Paris, France; Poznan, Poland; Tartu, Estonia; and Zurich, Switzerland). Sampling sites were selected based on a double orthogonal gradient of size and connectivity and were urban green areas (e.g. parks, cemeteries). To characterize the flowering plants, two s...
Research agenda on biodiversity and ecosystem functions and services in Europea...
Pinho, Pedro; Casanelles-Abella, Joan; Luz, Ana Catarina; Kubicka, Anna Maria; Branquinho, Cristina; Laanisto, Lauri; Neuenkamp, Lena; Alós Ortí, MartaCities are challenging environments for human life, because of multiple environmental issues driven by urbanization. These can sometimes be mitigated through ecosystem services provided by different functions supported by biodiversity. However, biodiversity in cities is affected by numerous factors, namely habitat loss, degradation, and fragmentation, as well as pollution, altered climate, and new biotic challe...
Response of bats and nocturnal insects to urban green areas in Europe
Villarroya-Villalba, Lucía; Casanelles-Abella, Joan; Moretti, Marco; Pinho, Pedro; Samson, Roeland; Van Mensel, Anskje; Chiron, FrançoisAnimal biodiversity in cities is generally expected to be uniformly reduced, but recent studies show that this is modulated by the composition and configuration of Urban Green Areas (UGAs). UGAs represent a heterogeneous network of vegetated spaces in urban settings that have repeatedly shown to support a significant part of native diurnal animal biodiversity. However, nocturnal taxa have so far been understudi...
