Differential effects of food restriction and warming in the two-spotted goby: I...
Lopes, Ana F.; Murdoch, Robyn; Cardoso, Sara D.; Madeira, Carolina; Costa, Pedro M.; Félix, Ana Sofia; Oliveira, Rui Filipe; Bandarra, NarcisaClimate change is a growing threat to marine organisms and ecosystems, and it is already modifying ocean properties by, for example, increasing temperature and decreasing pH. Increasing water temperature may also lead to an impairment of primary productivity and an overall depletion of available zooplankton. Understanding how the crossover between warming and zooplankton availability impacts fish populations ha...
Boat noise impacts Lusitanian toadfish breeding males and reproductive outcome
Amorim, Maria Clara P; Vieira, Manuel; Meireles, Gabriela; Novais, Sara C; Lemos, Marco F.L.; Modesto, Teresa; Alves, Daniel; Zuazu, Ana; Lopes, Ana F.Anthropogenic noise is a growing threat to marine organisms, including fish. Yet very few studies have addressed the impact of anthropogenic noise on fish reproduction, especially in situ. In this study, we investigated the impacts of boat noise exposure in the reproductive success of wild Lusitanian toadfish (Halobatrachus didactylus), a species that relies on advertisement calls for mate attraction, using beh...

Elevated temperature, but not decreased pH, impairs reproduction in a temperate...
Lopes, Ana F.; Faria, Ana M.; Dupont, SamFish reproductive success is linked to the ability of couples to mate and produce clutches that successfully hatch. Environmental stressors like high temperature and low pH can jeopardize this energetically costly process. In this study, exposure to high temperature and low pH was tested on a marine temperate species, Gobiusculus flavescens, to evaluate effects on reproductive performance. Breeding pairs were a...
Reproductive trade-offs in a temperate reef fish under high pCO2 levels
Faria, Ana Margarida; Lopes, Ana F.; Silva, Cátia Sofia Esteves da; Novais, Sara C.; Lemos, Marco F. L.; Gonçalves, Emanuel JoãoFishes are currently facing novel types of anthropogenic stressors that have never experienced in their evolutionary history, such as ocean acidification. Under these stressful conditions, energetically costly processes, such as reproduction, may be sacrificed for increased chances of survival. This trade-off does not only affect the organism itself but may result in reduced offspring fitness. In the present st...
Sand smelt ability to cope and recover from ocean's elevated CO2 levels
Silva, Cátia Sofia Esteves da; Lemos, Marco F. L.; Faria, Ana Margarida; Lopes, Ana F.; Mendes, Susana; Gonçalves, Emanuel João; Novais, Sara C.Considered a major environmental concern, ocean acidification has induced a recent research boost into effects on marine biodiversity and possible ecological, physiological, and behavioural impacts. Although the majority of literature indicate negative effects of future acidification scenarios, most studies are conducted for just a few days or weeks, which may be insufficient to detect the capacity of an organi...

Effects of high pCO2 on early life development of pelagic spawning marine fish
Faria, Ana Margarida; Filipe, Soraia; Lopes, Ana F.; Oliveira, Ana P.; Gonçalves, Emanuel João; Ribeiro, LauraThe present study investigated the effect of elevated pCO2 on the development of early stages of the pelagic spawning marine fish Solea senegalensis, Diplodus sargus and Argyrosomus regius. Eggs and larvae were reared under control (pH 8.0, ,570 matm) and two elevated pCO2 conditions (pH 7.8, ,1100 matm; pH 7.6, ,1900 matm) until mouth opening (3 days post-hatching). Egg size did not change with exposure to ele...
