A critical approach to existing management perspectives in Scuba Diving: A step...
Hipólito, Cláudia; Gonçalves, Jorge Manuel Santos; Gonçalves, Jorge; Calado, HelenaThere are a considerable number of studies reporting the negative impacts of recreational diving and their causes, yet there is a gap in the information regarding the aspects of activity management. This paper presents a systematic approach to the management measures found in the literature. A large part of the measures identified address stakeholders’ awareness, data on the activity, and implementing adapted m...
Strategic scenarios for maritime spatial planning in an European outermost regi...
Calado, Helena; Vergílio, Marta; Caña-Varona, Mario; Pegorelli, Camila; Hipólito, Cláudia; Silva, Aida; Carreira, Gilberto; Paramio, MariaThe Maritime Spatial Planning process plans towards a desired future (Vision/Goal). Such vision is usually an integration of various aspirations from different stakeholders and sectors that depend on the related policy/ governance framework. In this sense, a tool such as scenario-building is of paramount importance to MSP once it helps decision-makers visualize the future that might unfold due to specific the a...

Calado, Helena; Pegorelli, Camila; Vergílio, Marta H. S.; Hipólito, Cláudia; Campos, Aldino; Moniz, Fabiana; Costa, Ana Cristina; Silva, C. Pereira daScenarios constitute narratives or storylines that reasonably describe how the future is likely to unfold. The usefulness of scenarios in Maritime Spatial Planning (MSP) is now recognised within policy and research, with many institutions urging the development of likely trajectories in the future state of the marine environment and space. However, little progress exists in the actual development and applicatio...

Frondose and turf-dominated marine habitats support distinct trophic pathways: ...
Hipólito, Cláudia; Neto, Raul M. A.; Costa, Tarso; Dionísio, Maria Ana; Prestes, Afonso L.; Azevedo, José M. N.; Martins, Gustavo M.; Neto, Ana I.Marine vegetation plays an important structuring role, delivering key functions and services to coastal systems the extent of which depends on the foundation species and their architecture. In increasingly urbanised coastlines, turf-forming macroalgae are replacing frondose morphotypes. Trophic relationships within these systems can be studied through stable isotope analysis of the different food web compartmen...
Differences in the structure and functioning of two communities : frondose and ...
Martins, Gustavo M.; Hipólito, Cláudia; Parreira, Filipe; Prestes, Afonso L.; Dionísio, Maria Ana; Azevedo, José M. N.; Neto, Ana I.In many coastal regions, vegetated habitats (e.g. kelps forests, seagrass beds) play a key role in the structure and functioning of shallow subtidal reef ecosystems, by modifying local environmental conditions and by providing food and habitat for a wide range of organisms. In some regions of the world, however, such idiosyncratic ecosystems are largely absent and are often replaced by less notable ecosystem fo...
Wastewater matrix effect on disinfection with lp/uv and mp/uv radiation
Salgado, Ricardo; Hipólito, Cláudia; Galhanas, Dina; Epifâneo, Lisete; Noronha, João PauloThe disinfection of the wastewater effluents is important to reduce the pathogenic microorganism impact in the environment. UV radiation is one of the technologies used for this purposed. The wastewater characteristics, such as dissolved organic compounds or the presence of suspended solids can affect the efficiency of the faecal coliform bacteria removal in the disinfection process by ultraviolet (UV) radiatio...
Contributo para a inventariação da biodiversidade marinha da ilha de Santa Maria
Botelho, Andrea Z.; Dionísio, Maria Ana; Cunha, Andreia; Torres, Paulo; Monteiro, Sandra; Geraldes, Dinis; Hipólito, Cláudia; Parente, Manuela I.Na XIV Expedição Cientifica à ilha de Santa Maria 2009, organizada pelo Departamento de Biologia da Universidade dos Açores, foram realizados vários trabalhos em diversos locais do litoral da ilha, tendo como objectivo o registo, recolha e identificação de espécies marinhas, tendo sido feita amostragem de fauna e flora intertidal e subtidal (em mergulho com escafandro autónomo). Em cada um dos locais de amostra...
