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...
Urban Green Connectivity Assessment: A Comparative Study of Datasets in Europea...
Aleixo, Cristiana; Branquinho, Cristina; Laanisto, Lauri; Tryjanowski, Piotr; Niinemets, Ülo; Moretti, Marco; Samson, Roeland; Pinho, PedroUrban biodiversity and ecosystem services depend on the quality, quantity, and connectivity of urban green areas (UGAs), which are crucial for enhancing urban livability and resilience. However, assessing these connectivity metrics in urban landscapes often suffers from outdated land cover classifications and insufficient spatial resolution. Spectral data from Earth Observation, though promising, remains underu...
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...
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...
Dimensions of invasiveness: Links between local abundance, geographic range siz...
Fristoe, Trevor S; Chytrý, Milan; Dawson, Wayne; Essl, Franz; Heleno, Ruben; Kreft, Holger; Maurel, Noëlie; Pergl, Jan; Pyšek, Petr; Seebens, HannoUnderstanding drivers of success for alien species can inform on potential future invasions. Recent conceptual advances highlight that species may achieve invasiveness via performance along at least three distinct dimensions: 1) local abundance, 2) geographic range size, and 3) habitat breadth in naturalized distributions. Associations among these dimensions and the factors that determine success in each have y...
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...
Integration of C1 and C2 metabolism in trees
Jardine, Kolby J.; Souza, Vinícius Fernandes de; Oikawa, Patricia Yoshino; Higuchi, Niro; Bill, Markus; Porras, Rachel C.; Niinemets, ÜloC1 metabolism in plants is known to be involved in photorespiration, nitrogen and amino acid metabolism, as well as methylation and biosynthesis of metabolites and biopolymers. Although the flux of carbon through the C1 pathway is thought to be large, its intermediates are difficult to measure and relatively little is known about this potentially ubiquitous pathway. In this study, we evaluated the C1 pathway an...
