Uma educação diferenciada:
Pimentel, MartaO presente estudo, centrado numa pesquisa sobre a utilização da diferenciação pedagógica, em contexto de educação pré-escolar, teve como principal objetivo refletir sobre a forma como os educadores de infância utilizam a mesma. Para atingir este objetivo investigámos, no plano teórico, o conceito de diferenciação pedagógica e as suas dimensões, a sua importância em contexto de educação pré-escolar e a importânc...
Ocean acidification dampens physiological stress response to warming and contam...
Sampaio, Eduardo; Lopes, Ana Rita; Francisco, Sofia; Paula, José Ricardo; Pimentel, Marta; Luísa Maulvault, Ana; Repolho, Tiago; F. Grilo, TiagoIncreases in carbon dioxide (CO2) and other greenhouse gases emissions are changing ocean temperature and carbonate chemistry (warming and acidification, respectively). Moreover, the simultaneous occurrence of highly toxic and persistent contaminants, such as methylmercury, will play a key role in further shaping the ecophysiology of marine organisms. Despite recent studies reporting mostly additive interaction...
Physiological resilience of a temperate soft coral to ocean warming and acidifi...
Lopes, Ana Rita; Faleiro, Filipa; Rosa, Inês C.; Pimentel, Marta; Trubenbach, Katja; Repolho, Tiago; Diniz, Mário S.; Rosa, RuiAtmospheric concentration of carbon dioxide (CO2) is increasing at an unprecedented rate and subsequently leading to ocean acidification. Concomitantly, ocean warming is intensifying, leading to serious and predictable biological impairments over marine biota. Reef-building corals have proven to be very vulnerable to climate change, but little is known about the resilience of non-reef-building species. In this ...
Different ecophysiological responses of freshwater fish to warming and acidific...
Jesus, Tiago F.; Rosa, Inês C.; Repolho, Tiago; Lopes, Ana Rita; Pimentel, Marta; Almeida-Val, Vera M.F.; Coelho, Maria M.; Rosa, RuiFuture climate change scenarios predict threatening outcomes to biodiversity. Available empirical data concerning biological response of freshwater fish to climate change remains scarce. In this study, we investigated the physiological and biochemical responses of two Iberian freshwater fish species (Squalius carolitertii and the endangered S. torgalensis), inhabiting different climatic conditions, to projected...
Small pelagics in a changing ocean : Biological responses of sardine early stag...
Faleiro, Filipa; Pimentel, Marta; Pegado, Maria Rita; Bispo, Regina; Lopes, Ana Rita; Diniz, Mário S.; Rosa, RuiSmall pelagic fishes are known to respond rapidly to changes in ocean climate. In this study, we evaluate the effects of future environmental warming (+2°C) during the early ontogeny of the European sardine, Sardina pilchardus. Warming reduced the survival of 30-day-old larvae by half. Length at hatching increased with temperature as expected, but no significant effect was observed on the length and growth at 3...
Foraging behaviour, swimming performance and malformations of early stages of c...
Pimentel, Marta; Faleiro, Filipa; Marques, Tiago A.; Bispo, Regina; Dionísio, Gisela João Ribeiro Lemos; Faria, Ana Margarida; Machado, JorgeEarly life stages of many marine organisms are being challenged by climate change, but little is known about their capacity to tolerate future ocean conditions. Here we investigated a comprehensive set of biological responses of larvae of two commercially important teleost fishes, Sparus aurata (gilthead seabream) and Argyrosomus regius (meagre), after exposure to future predictions of ocean warming (+4 °C) and...

Deficit in digestive capabilities of bamboo shark early stages under climate ch...
Rosa, Rui; Pimentel, Marta; Galan, Juan; Baptista, Miguel; Lopes, Vanessa M.; Couto, Ana; Guerreiro, Miguel; Sampaio, Eduardo; Castro, JoanaLittle empirical information is currently available on the potential effects of acidification and/or warming in sharks, but none exist about digestive capabilities under such future conditions. Here, we investigated the impact of both acidification (ΔpH = 0.5) and warming (+4; 30 °C) on the digestive enzyme levels of recently hatched tropical bamboo shark (Chiloscyllium punctatum). Thirty days post-hatching, ju...
Neuro-oxidative damage and aerobic potential loss of sharks under elevated CO2 ...
Rosa, Rui; Paula, José Ricardo; Sampaio, Eduardo; Pimentel, Marta; Lopes, Ana Rita; Baptista, Miguel; Guerreiro, Miguel; Santos, Catarina; Campos, DerekSharks occupy high trophic levels in marine habitats and play a key role in the structure and function of marine communities. Their populations have been declining worldwide by ≥90 %, and their adaptive potential to future ocean conditions is believed to be limiting. Here we experimentally exposed recently hatched bamboo shark (Chiloscyllium punctatum) to the combined effects of tropical ocean warming (+4; 30 °...
Seahorses under a changing ocean: the impact of warming and acidification on th...
Faleiro, Filipa; Baptista, Miguel; Santos, Catarina; Aurélio, Maria L.; Pimentel, Marta; Pegado, Maria Rita; Paula, José Ricardo; Calado, RicardoSeahorses are currently facing great challenges in the wild, including habitat degradation and overexploitation, and how they will endure additional stress from rapid climate change has yet to be determined. Unlike most fishes, the poor swimming skills of seahorses, along with the ecological and biological constraints of their unique lifestyle, place great weight on their physiological ability to cope with clim...
