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 ...
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...
Differential impacts of ocean acidification and warming on winter and summer pr...
Rosa, Rui; Trubenbach, Katja; Pimentel, Marta S.; Boavida-Portugal, Joana; Faleiro, Filipa; Baptista, Miguel; Dionísio, Gisela; Calado, RicardoLittle is known about the capacity of early life stages to undergo hypercapnic and thermal acclimation under the future scenarios of ocean acidification and warming. Here, we investigated a comprehensive set of biological responses to these climate change-related variables (2°C above winter and summer average spawning temperatures and ΔpH=0.5 units) during the early ontogeny of the squid Loligo vulgaris. Embryo...
Lower hypoxia thresholds of cuttlefish early life stages living in a warm acidi...
Rosa, Rosa; Trubenbach, Katja; Repolho, Tiago; Pimentel, Marta; Faleiro, Filipa; Boavida-Portugal, Joana; Baptista, Miguel; Lopes, Vanessa M.The combined effects of future ocean acidification and global warming on the hypoxia thresholds of marine biota are, to date, poorly known. Here, we show that the future warming and acidification scenario led to shorter embryonic periods, lower survival rates and the enhancement of premature hatching in the cuttlefish Sepia officinalis. Routine metabolic rates increased during the embryonic period, but environm...
