Absence of cellular damage in tropical newly hatched sharks (Chiloscyllium plag...
Lopes, Ana Rita; Sampaio, Eduardo; Santos, Catarina; Couto, Ana; Pegado, Maria Rita; Diniz, Mário S.; Munday, Philip L.; Rummer, Jodie L.; Rosa, RuiSharks have maintained a key role in marine food webs for 400 million years and across varying physicochemical contexts, suggesting plasticity to environmental change. In this study, we investigated the biochemical effects of ocean acidification (OA) levels predicted for 2100 (pCO2 ~ 900 μatm) on newly hatched tropical whitespotted bamboo sharks (Chiloscyllium plagiosum). Specifically, we measured lipid, protei...
Painted Goby Larvae under high-CO2 fail to recognize reef sounds
Castro, Joana M.; Amorim, Maria Clara Pessoa; Oliveira, Ana P.; Gonçalves, Emanuel João; Munday, Philip L.; Simpson, Stephen D.; Faria, Ana MargaridaAtmospheric CO2 levels have been increasing at an unprecedented rate due to anthropogenic activity. Consequently, ocean pCO2 is increasing and pH decreasing, affecting marine life, including fish. For many coastal marine fishes, selection of the adult habitat occurs at the end of the pelagic larval phase. Fish larvae use a range of sensory cues, including sound, for locating settlement habitat. This study teste...
Biological responses of sharks to ocean acidification
Rosa, Rui; Rummer, Jodie L.; Munday, Philip L.Sharks play a key role in the structure of marine food webs, but are facing major threats due to overfishing and habitat degradation. Although sharks are also assumed to be at relatively high risk from climate change due to a low intrinsic rate of population growth and slow rates of evolution, ocean acidification (OA) has not, until recently, been considered a direct threat. New studies have been evaluating the...
Behavioural lateralization and shoaling cohesion of fish larvae altered under o...
Lopes, Ana Filipa; Morais, Pedro; Pimentel, Marta S,; Rosa, Rui; Munday, Philip L.; Gonçalves, Emanuel João; Faria, Ana MargaridaRecent 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...
