- Bio ilhas project: blending research with scientific and educational disseminationPublication . Ferreira, Nathália Borges Bartoli; Sá, Isabel; Fachada, Ivone; Pereira, Ana; Calheiros, Cristina; Geraldes, Ana MariaFreshwater ecosystems provide humanity with a wide range of services, particularly water supply and purification. However, many of these ecosystems and their associated biodiversity are threatened significantly. Therefore, the introduction of nature-based solutions, such as floating wetland islands, in these ecosystems can contribute to the improvement of water quality and habitat provision and, when integrated with an environmental education context, can be used as powerful tools to engage students, tourists, and the general public in interactive experiences, allowing them to become more familiar with the function of freshwater ecosystems and biodiversity. Both the Fervença and Côa rivers are located in the Douro basin. The Fervença is an urban river, about 25 km long, which flows through Bragança. Along its course, it encounters non-point and point sources of pollution. In the urban core, the riverbed has been regulated, an artificial riverbank has been created, and the riparian forest has been partially removed. In this area, algal blooms occur, especially in summer, which negatively affect the water and visual quality of the area. The Côa is about 140 km long and flows through an agricultural and natural landscape. Nevertheless, the longitudinal connectivity of the river is reduced by several weirs, and the coffer dam has never been removed, even after a dam construction project was abandoned due to the discovery of important archaeological heritage. The Bio ilhas project, led by the Bragança Ciência Viva Science Center, aims to place floating islands in the urban core of Fervença and the lentic area influenced by the Côa coffer dam, the river areas affected by human activity at different levels. Therefore, the present communication aims to present the Bio ilhas project and the related activities conciliating research with scientific and educational dissemination to ultimately contribute to freshwater ecosystem conservation.
- Projeto Bio ilhas: ciência, educação e sensibilização para a conservação de ecossistemas ribeirinhosPublication . Ferreira, Nathália Borges Bartoli; Sá, Isabel; Pinto, Mónica; Nogueira, Clotilde; Fachada, Ivone; Calheiros, Cristina; Geraldes, Ana MariaO projeto Bio Ilhas está estruturado em três Componentes: Científica, Educativa e de Divulgação e envolve a instalação de ilhas flutuantes no troço urbano do Rio Fervença(Bragança, Portugal). Assim, foram selecionadas duas matrizes flutuantes quadradas de 4m2(cada uma de 2x2m), uma de poliestireno expandido reciclado e outra de aglomerado de cortiça. As planta escolhidas para integrar as Bio Ilhas foram as espécies salgueirinha (Lythrum salicaria), junco (Juncus effusus) e o lírio amarelo (Iris pseudacorus). Avaliar a viabilidade da utilização das ilhas flutuantes na remediação do troço urbano do rio Fervença; Avaliar a importância destas estruturas para o incremento da biodiversidade aquática e terrestre; Aumentar a literacia científica da comunidade sobre os rios.
- Promoting species diversity: understanding Sweet Chestnut within regeneration of Scots pine standsPublication . Patrício, Maria Sameiro; Nunes, LuísPine forests exhibit a natural gradual transition to mixed plantations, where hardwoods like sweet chestnut (Castanea sativa Mill.) and oaks begin to establish as ecological succession progress. However, the persistence of chestnut in conifer stands depends heavily on surrounding chestnut stands and light availability. In this case-study of Serra da Nogueira, Portugal – a region characterized by a mosaic of habitats formed by mountain agriculture, with extensive Pyrenean oak forests interspersed with some stands of other hardwoods and conifers, including scots pine (Pinus sylvestris L.) - chestnut persists in the natural regeneration of these stands largely due to existing forest and agroforestry chestnut stands. Advanced regeneration in the understory of Scots pine stands suggests that the chestnut can persist in the natural regeneration dynamics, contributing to the formation of more resilient and biodiverse mixed stands.
