Urban intensity gradients shape community structure, life‐history traits and pe...
Casanelles‐Abella, Joan; Pellissier, Loïc; Aleixo, Cristiana; Orti, Marta Alós; Chiron, François; Deguines, Nicolas; Laanisto, Lauri; Myczko, ŁukaszUrban ecosystems are formed by pronounced socio-ecological gradients, which are distinct from other ecosystems and can simultaneously filter and promote taxa, ultimately affecting their interactions. However, the strength of the effect of filtering and facilitation across the different trophic levels could vary among biotic and abiotic factors. Here, we investigate the effects of habitat amount, temperature and...
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...
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...

How wild bees find a way in European cities: Pollen metabarcoding unravels mult...
Casanelles‐Abella, Joan; Müller, Stefanie; Keller, Alexander; Aleixo, C.; Alós Orti, Marta; Chiron, François; Deguines, Nicolas; Hallikma, TiitUrban ecosystems can sustain populations of wild bees, partly because of their rich native and exotic floral resources. A better understanding of the urban bee diet, particularly at the larval stage, is necessary to understand biotic interactions and feeding behaviour in urban ecosystems, and to promote bees by improving the management of urban floral resources. We investigated the larval diet and distribution ...
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...
