Macrofaunal community abundance and diversity and talitrid orientation as poten...
Nourissona, Delphine Hélène; Bessa, Filipa; Scapini, Felicita; Marques, João CarlosIn the last decades the increasing urban development on coastal areas have produced extensive modifications on shores all over the world, making critical the active management of pressures on sandy beaches. The use of engineering solutions to counteract beach erosion has been significantly increasing; the ecological indicators used to monitor these interventions generally focus on short- and medium-term effects...
Niche segregation amongst sympatric species at exposed sandy shores with contra...
Bessa, Filipa; Baeta, Alexandra; Marques, João CarlosWrack supplies (macroalgae, seagrasses and carrion) are a common feature of sandy beaches worldwide. These allochthonous inputs are a potential high-quality food subsidy for beach fauna, but little is known about the feeding ecology and niche segregation strategies of these species in beaches with limited wrack availabilities. We used stable isotopic ratios of nitrogen and carbon to examine the diets and niche ...
Temporal changes in macrofauna as response indicator to potential human pressur...
Bessa, Filipa; Gonçalves, Sílvia C.; Franco, João N.; André, José N.; Cunha, Pedro P.; Marques, J. C.Sandy beaches are natural dynamic ecosystems, which are becoming worldwide increasingly disturbed by intensive human direct use, coastal development and erosive evolution. In this study, we have examined whether ten years of potential increased human pressures have resulted in significant changes in the macrofaunal assemblages’ structure and composition of two mesotidal sandy beaches (Cabedelo – urban beach, an...
Avaliação e substituição de produtos químicos no sector BOF da Swedwood Portugal
Bessa, Filipa Manuel Ferreira deA crescente preocupação com aspectos ambientais tornou-se uma questão incontornável para as empresas. Assim, a legislação aplicável obriga a maior controlo de qualquer tipo de perigo que ponha em causa a saúde humana ou o ambiente. Deste modo, a Swedwood Portugal é obrigada a implementar algumas medidas de controlo dos produtos químicos. Assim, os objectivos deste estágio curricular fundamentamse em identificar...
