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...
Assessing Ecological Gains: A Review of How Arthropods, Bats and Birds Benefit ...
Tiago, Patrícia; Leal, Ana I.; Silva, Cristina MatosBecause of the immense amount of infrastructure in cities, the introduction of vegetation into these constructions is expected to play a critical role in reducing the heat island effect, in mitigating the effects of climate change, and in supporting habitat connectivity and associated biodiversity. Although there is the perception that these solutions can improve the biodiversity of cities, their real value is ...
Small shrubby patches increase bird taxonomic and functional richness of wood-p...
Lopes, Paula C.; Palmeirim, Jorge M.; Leal, Ana I.Wood-pastures are semi-natural systems that combine a grazed grassland with a tree layer. Shrubs are often controlled, mostly to improve grazing potential, resulting in a reduction of the available ecological niches. From a conservation perspective, it is thus important to identify management practices that counter this reduction. Our overall objective was to determine the value of small shrubby patches to incr...
Effects of ungulates on oak regeneration in Mediterranean woodlands: A meta-ana...
Leal, Ana I.; Bugalho, Miguel N.; M. Palmeirim, JorgeMediterranean-climate oak woodlands, including those in North America and in the Mediterranean basin, are human-shaped ecosystems with high biodiversity value, which generate different ecosystem services, including grazing resources for livestock production. Low oak recruitment rates, however, are affecting the ecological sustainability of these ecosystems. Understanding the factors affecting recruitment dynami...
Contributions to the design of mobile applications for visitors of Botanical Ga...
Postolache, Stefan; Torres, Rafael; Afonso, Ana Paula; Carmo, Maria Beatriz; Cláudio, Ana Paula; Domingos, Dulce; Ferreira, António; Barata, AnaBotanical Gardens are among the most visited touristic attractions, offering scientific, educational, cultural and leisure activities to preserve and enhance heritage and disseminating specialised knowledge on science and history. There are several mobile applications (apps) to support visitors of Botanical Gardens, which explore augmented reality technologies to enrich their experience. Our work aims to system...
Niche differences may reduce susceptibility to competition between native and n...
Soares, Filipa C.; Leal, Ana I.; M. Palmeirim, Jorge; F. De Lima, RicardoAim Few bird extinctions on oceanic island have been attributed to competition with non-native species, even though it might be an overlooked driver of biodiversity loss. We evaluate the potential competition between native and non-native island bird species, identifying species and island characteristics that enhance it and may promote future extinctions. Location Seventy-three (>100 km2) oceanic islands world...
Land‐use intensification promotes non‐native species in a tropical island bird ...
Soares, F. C.; Panisi, Martina; Sampaio, H.; Soares, E.; Santana, A.; Buchanan, G. M.; Leal, Ana I.; M. Palmeirim, Jorge; F. De Lima, RicardoHabitat loss and non-native species are two key drivers of biodiversity decline. The importance of their interactions is widely recognized, but remains poorly understood. We used the endemic-rich bird assemblage of São Tomé Island to study this type of interactions. We built species-specific binomial generalized linear models for 33 terrestrial bird species, based on presence–absence data from 2398 sampling poi...
Increasing biodiversity in wood-pastures by protecting small shrubby patches
Oksuz, Duygu P.; Aguiar, Carlos A.S.; Tápia, Susana; Llop, Esteve; Lopes, Paula; Serrano, Artur; Leal, Ana I.; Branquinho, Cristina; Correia, OtiliaWood-pastures are grazed systems, widespread across Europe, where natural and economic values often co-exist. Social and economic changes in Europe generate both threats and opportunities to these systems, calling for new or improved management strategies. We studied the potential of increasing the biodiversity of wood-pastures through the promotion of small-scale habitat diversification. More specifically, we ...
The contribution of small shrubby patches to the functional diversity of wood-p...
Oksuz, Duygu P.; Aguiar, Carlos A.S.; Tápia, Susana; Llop, Esteve; Lopes, Paula; Serrano, Artur; Leal, Ana I.; Correia, Otilia; Matos, PaulaWood-pastures are grazed systems resulting from a long-term use of natural woodlands by humans. These social-ecological systems, covering vast areas of Europe and other temperate regions, have both high biodiversity and economic values, so many are classified as High Nature Value Farmlands. However, in some regions a loss of spatial heterogeneity threatens this natural value. We investigated the potential contr...
