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...
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...
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...

Early-life exposure to climate change impairs tropical shark survival
Rosa, Rui; Baptista, Miguel; Lopes, Vanessa M.; Pegado, Maria Rita; Ricardo Paula, José; Trubenbach, Katja; Leal, Miguel Costa; Calado, RicardoSharks are one of the most threatened groups of marine animals worldwide, mostly owing to overfishing and habitat degradation/loss. Although these cartilaginous fish have evolved to fill many ecological niches across a wide range of habitats, they have limited capability to rapidly adapt to human-induced changes in their environments. Contrary to global warming, ocean acidification was not considered as a direc...
Ocean cleaning stations under a changing climate: biological responses of tropi...
Rosa, Rui; Lopes, Ana Rita; Pimentel, Marta; Faleiro, Filipa; Baptista, Miguel; Trübenbach, Katja; Narciso, Luis; Dionísio, Gisela; Pegado, Maria RitaCleaning symbioses play an important role in the health of certain coastal marine communities. These interspecific associations often occur at specific sites (cleaning stations) where a cleaner organism (commonly a fish or shrimp) removes ectoparasites/damaged tissue from a 'client' (a larger cooperating fish). At present, the potential impact of climate change on the fitness of cleaner organisms remains unknow...
