Urban trees through a functional traits’ lens: Exploring the interplay between ...
Grilo, Ana Filipa; McPhearson, Timon; Aleixo, Cristiana; Santos-Reis, Margarida; Branquinho, CristinaUrban trees’ functional traits influence their resilience to environmental changes and the delivery of ecosystem services. However, research on classifying urban trees into functional groups based on species traits - clusters of species with similar responses to environmental stressors and providing similar ecosystem services - and exploring the factors that shape their distribution is limited. This study class...
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...
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 However, assessing these connectivity metrics in urban landscapes often suffers from outdated land cover classifications and insufficient spatial resolution.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...
Where the not-so-wild things are in cities? The influence of social-ecological ...
Grilo, Ana Filipa; McPhearson, Timon; Nunes, Alice; Aleixo, Cristiana; Santos-Reis, Margarida; Branquinho, CristinaGreen infrastructure plays an essential role in cities due to the ecosystem services it provides. However, these elements are shaped by social and ecological factors that influence their distribution and diversity, affecting ecological functions and human well-being. Here, we analyzed neighborhood tree distribution - trees in pocket parks, squares and along streets – in Lisbon (Portugal) and modelled tree abund...
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...
Current and historical factors drive variation of reproductive traits in unisex...
Boquete, María Teresa; Varela, Zulema; Fernández, José Angel; Calleja, Juan Antonio; Branquinho, Cristina; Chilà, Antonina; Cronberg, NilsUnisexual bryophytes provide excellent models to study the mechanisms that regulate the frequency of sexual versus asexual reproduction in plants, and their ecological and evolutionary implications. Here, we determined sex expression, phenotypic sex ratio, and individual shoot traits in 242 populations of the cosmopolitan moss Pseudoscleropodium purum spanning its whole distributional range. We tested whether n...
Wild bee larval food composition in five European cities
Casanelles‐Abella, Joan; Keller, Alexander; Müller, Stefanie; Aleixo, Cristiana; Alós‐Orti, Marta; Chiron, François; Laanisto, Lauri; Myczko, ŁukaszUrbanization poses threats and opportunities for the biodiversity of wild bees. At the same time, cities can harbor diverse wild bee assemblages, partly due to the unique plant assemblages that provide resources. While bee dietary preferences have been investigated in various studies, bee dietary studies have been conducted mostly in nonurban ecosystems and data based on plant visitation observations or palynol...
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...
Local-scale factors matter for tree cover modelling in Mediterranean drylands
Príncipe, Adriana; Nunes, Alice; Pinho, Pedro; Aleixo, Cristiana; Neves, Nuno; Branquinho, CristinaForests contribute directly to ecosystem structure and functioning, maintaining biodiversity, acting as a climate regulator and reducing desertification. To better manage forests, it is essential to have high-resolution forest models and appropriate spatial-explicit variables able to explain tree cover at different scales, including the management scale. Most tree cover models rely only on broad-scale variables...
