Dramatic changes in the structure of shallow-water marine benthic communities f...
Faria, João; Prestes, Afonso L.; Moreu, Ignacio; Cacabelos, Eva; Martins, Gustavo M.Biological invasions are considered one of the most important drivers of biodiversity loss. Here we use a before-after-control-impact (BACI) design to investigate the impact of Rugulopteryx okamurae on the structure of shallow-water marine benthic communities in São Miguel island, Azores. After its first appearance in 2019, R. okamurae has rapidly invaded much of the southern coast of the island, where it becam...
Ervilia castanea (Mollusca, Bivalvia) populations adversely affected at CO₂ see...
Martins, Marta; Silva, Marina Carreiro; Martins, Gustavo M.; Ramos, Joana B.; Viveiros, Fátima; Couto, Ruben P.; Parra, Hugo; Monteiro, JoãoSites with naturally high CO₂ conditions provide unique opportunities to forecast the vulnerability of coastal ecosystems to ocean acidification, by studying the biological responses and potential adaptations to this increased environmental variability. In this study, we investigated the bivalve Ervilia castanea in coastal sandy sediments at reference sites and at volcanic CO₂ seeps off the Azores, where the pH...
Gastropods with different development modes respond differently to habitat frag...
Cacabelos, Eva; Neto, Ana I.; Martins, Gustavo M.The role of the human-made structures in coastal ecosystems can determine the spatial distribution or patterns of spatial abundances of marine organisms. To contribute to the understanding of linkages between different components of habitats (i.e. natural and artificial structures), we explored the role of type of larval development (planktotrophic vs. non-planktotrophic) on patterns of spatial variation of gas...
Centrally acting antihypertensives change the psychogenic cardiovascular reacti...
Mendonça, Michelle M.; Costa, Amanda N.; Moraes, Gean C.A.; Martins, Gustavo M.; Almeida, Aline F.; Rincon, Gabriel C.N.; Siqueira, João P.R.Made available in DSpace on 2021-06-25T11:12:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Clonidine (CL) and Rilmenidine (RI) are among the most frequently prescribed centrally acting antihypertensives. Here, we compared CL and RI effects on psychogenic cardiovascular reactivity to sonant, luminous, motosensory, and vibrotactile stimuli during neurogenic hypertension. The femoral artery and ...
Macaronesia as a Fruitful Arena for Ecology, Evolution, and Conservation Biology
Florencio, Margarita; Patiño, Jairo; Nogué, Sandra; Traveset, Anna; Borges, Paulo A. V.; Schaefer, Hanno; Amorim, Isabel R.; Arnedo, Miquel A.Research in Macaronesia has led to substantial advances in ecology, evolution and conservation biology. We review the scientific developments achieved in this region, and outline promising research avenues enhancing conservation. Some of these discoveries indicate that the Macaronesian flora and fauna are composed of rather young lineages, not Tertiary relicts, predominantly of European origin. Macaronesia also...
Predicting the ecological impact of a recent range expansion in the structure o...
Martins, Gustavo M.; Prestes, Afonso L.; Faria, Joao; Neto, Ana I.Predicting the consequences of recent changes in species distributional ranges is paramount. The trochid Phorcus sauciatus has recently colonised the Azores and is the only intertidal trochid in these islands. In this study we used experimental mesocosms to examine whether its addition to the remainder of the intertidal assemblage of grazers composed of littorinids and patellids affects the structure of epilith...

The Azorean edible abalone Haliotis tuberculata, an alternative heavy metal-fre...
Torres, Paulo; Rodrigues, Armindo; Prestes, Afonso L.; Neto, Ana I.; Álvaro, Nuno V.; Martins, Gustavo M.Abalones are considered a delicacy and exploited for food worldwide. In many places, overfishing has led to the decimation of wild stocks and many are now reared in aquaculture systems. In the Azores, there is no tradition of eating abalones and Haliotis tuberculata stocks are still virtually untouched. However, as tourism in the islands grows and the stocks of other shellfish diminish, there is an increasing p...
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...
