Co-design of a marine protected area zoning and the lessons learned from it
Horta e Costa, Barbara; Guimarães, Maria Helena; Rangel, Mafalda; Ressurreicão, Adriana; Monteiro, Pedro; Oliveira, Frederico; Bentes, LuísMarine Protected Areas (MPAs) are a tool to safeguard marine natural systems, yet their effectiveness depends on how well they are integrated into the existing socioeconomic context. Stakeholder engagement in MPA design can contribute to increasing integration. This study focuses on the co-design of an MPA between researchers, public administration, the private sector, and non-governmental organizations. The pr...
Effect of kind and method of fungicidal treatment of bean seed on infections by...
Gonçalves, E. J.; Muchovej, J. J.; Muchovej, Rosa M. C.To test the effect of seed treatment with fungicides on the development of mycorrhizal fungi, bean seeds were treated with fungicide dry or vehicled in the organic solvents, ethanol or dichloromethane and then planted in soil inoculated with the mycorrhizal fungus Glomus macrocarpum and/or the plant pathogenic fungus Fusarium solani. Measurements were made at 4 day intervals, to assess the presence of mycorrhiz...
Reproductive trade-offs in a temperate reef fish under high pCO2 levels
Faria, A. M.; Lopes, A. F.; Silva, C. S. E.; Novais, S. C.; Lemos, M. F. L.; Gonçalves, E. J.Fishes are currently facing novel types of anthropogenic stressors that have never experienced in their evolutionary history, such as ocean acidification. Under these stressful conditions, energetically costly processes, such as reproduction, may be sacrificed for increased chances of survival. This trade-off does not only affect the organism itself but may result in reduced offspring fitness. In the present st...
Larval development and allometric growth of the black-faced blenny Tripterygion...
Solomon, F. N.; Rodrigues, D.; Gonçalves, E. J.; Serrão, E. A.; Borges, R.Larval development and allometric growth patterns of the black-faced blenny Tripterygion delaisi are described from a larval series (body length, L-B = 3.30-12.10 mm) caught by light traps at the Arrabida Marine Park, Portugal. Larvae of T. delaisi possess distinctive morphometric and meristic characteristics which can be used to identify this species from related taxa. Pigmentation is sparse but characteristic...
Behavioural lateralization and shoaling cohesion of fish larvae altered under o...
Lopes, A. F.; Morais, P.; Pimentel, M.; Rosa, R.; Munday, P. L.; Gonçalves, E. J.; Faria, A. M.Recent studies have shown that the behaviour and development of coral reef fish larvae is hampered by projected future CO2 levels. However, it is uncertain to what extent this effect also occurs in temperate species. The effects that elevated pCO2 (~2000 µatm) levels, which are expected to occur in coastal upwelling regions in the future, have on shoaling behaviour and lateralization (turning preference) of fis...
Assessment of catches, landings and fishing effort as useful tools for MPA mana...
Batista, M. I.; Horta e Costa, Bárbara; Gonçalves, L.; Henriques, M.; Erzini, Karim; Caselle, J. E.; Gonçalves, E. J.; Cabral, H. N.Marine protected areas (MPAs) have been widely recognized as a tool to achieve both fisheries management and conservation goals. Simultaneously achieving these multiple goals is difficult due to conflicts between conservation (often long-term) and economic (often short-term) objectives. MPA implementation often includes additional control measures on fisheries (e.g. vessel size restrictions, gear exclusion, cat...
Early reserve effects linked to small home ranges of a commercial fish, Diplodu...
Abecasis, D.; Costa, B. H. E.; Afonso, P.; Gonçalves, E. J.; Erzini, KarimStudies that combine both the ecological responses of marine species and protection measures with movement patterns and habitat use are of major importance in order to better understand the performance of marine protected areas (MPA) and how species respond to their implementation. However, few studies have assessed MPA performance by relating local individual movement patterns and the observed reserve effects....
'Reserve effect' within a temperate marine protected area in the north-eastern ...
Horta e Costa, Bárbara; Erzini, Karim; Caselle, Jennifer E.; Folhas, Henrique; Gonçalves, E. J.Benefits of marine protected areas depend on local ecological and socio-cultural aspects which are critical to the success of the protection measures. In particular, before-after comparisons are indispensable to disentangle the effects of protection from those of different physical and ecological characteristics among areas. Using underwater visual surveys, we assessed whether biomass and abundance of temperate...
Short-term temporal fluctuation of very-nearshore larval fish assemblages at th...
Borges, R.; Vaz, J.; Serrão, Ester; Gonçalves, E. J.Understanding processes affecting fish recruitment and population connectivity is of major importance to the management of Marine Protected Areas. Fluctuations in recruitment of coastal fishes can be affected by processes occurring during the early life stages such as the dispersal and availability of larvae. In nearshore temperate environments, there is a lack of knowledge about the patterns of larval supply o...
Composition and temporal dynamics of a temperate rocky cryptobenthic fish assem...
Beldade, R.; Erzini, Karim; Gonçalves, E. J.Temporal variation in a temperate cryptobenthic fish assemblage at the Arrabida Marine Park (Portugal) was assessed by visual Surveys during 2002 and 2003. A total of 9596 fish from 11 families and 30 species was recorded. There were no changes in structure or density at the assemblage level between years, whereas diversity changed significantly due to a higher number of abundant species in the second year. A s...
