Early life stage mechanisms of an active fish species to cope with ocean warmin...
Lima, André R.A.; Booms, Emily M.; Lopes, Ana Rita; Martins-Cardoso, Sara; Novais, Sara C; Lemos, Marco F.L.; Ribeiro, Laura; Castanho, SaraOcean’s characteristics are rapidly changing, modifying environmental suitability for early life stages of fish. We assessed whether the chronic effects of warming (24 ◦C) and hypoxia (<2–2.5 mg L− 1 ) will be amplified by the combination of these stressors on mortality, growth, behaviour, metabolism and oxidative stress of early stages of the white seabream Diplodus sargus. Combined warming and hypoxia synergi...
Integrated behavioural and physiological responses of sand smelt larvae to the ...
Lima, André R.A.; Lopes, Ana Rita; Martins-Cardoso, Sara; Moutinho, Ariana B.; Lemos, Marco F.L.; Novais, Sara C; Faria, Ana M.Forecasts indicate that rising temperatures towards the future and the expansion of dead zones will change environmental suitability for fish early stages. Therefore, we assessed the chronic effects of warming (26 ◦C), hypoxia (<2–2.5 mg L− 1 ) or their combination on mortality rate, growth, behaviour, energy metabolism and oxidative stress using Atherina presbyter larvae as a model species. There were no diffe...
Turning up the heat: Effects of temperature on agonistic acoustic communication...
Penim, Jorge; Beauchaud, Marilyn; Millot, Morgane; Faria, Ana M.; Vieira, Manuel; Fonseca, Paulo; Vasconcelos, Raquel O.; Amorim, M. Clara P.Acoustic communication is linked to fitness traits in many animals, but under the current scenario of global warming, sound signals can be affected by rising temperatures, particularly in ectothermic organisms such as fishes. This study examines the effect of water temperature in acoustic communication in the two-spotted goby, Pomatoschistus flavescens. To address this, we looked at the effect of different temp...
Mating sounds in the two-spotted goby, Pomatoschistus flavescens: Effects of wa...
Millot, Morgane; Faria, Ana M.; Clara P Amorim, MariaAcoustic signals in teleost fishes play a fundamental role in reproduction. As fish are ectothermic animals, temperature has the potential to change their signal production and detection, with further implications for mating interactions. In this study, we describe the mating sounds made by the two-spotted goby, Pomatoschistus flavescens, for the first time and further investigate the effect of temperature on t...
Effects of temperature on acoustic and visual courtship and reproductive succes...
Albouy, Robin; Faria, Ana M.; Fonseca, Paulo J.; Amorim, ClaraFish are ectothermic and small changes in water temperature could greatly affect reproduction. The two-spotted goby is a small semi-pelagic species that uses visual and acoustic displays to mate. Here, we studied the effect of temperature (16 and 20 ◦C) on acoustic and visual courtship and associated reproductive success in 39 males. Temperature influenced male visual courtship performed outside the nest, but i...
Impact of anthropogenic noise on the survival and development of meagre (Argyro...
Trabulo, Rita; Amorim, M. Clara P.; Fonseca, Paulo J.; Vieira, Manuel; Matos, Manuel J. B.; Marin-Cudraz, Thibaut; Lemos, Marco F.L.; Novais, Sara C.The growth of human populations has been driving an unprecedent and widespread increase in marine traffic, posing a real threat to marine biodiversity. Even though we are now aware of the negative effects of shipping noise exposure on fish, information about the impact on their early life stages continues to lack. Meagre (Argyrosomus regius) is a vocal fish that uses estuaries with high levels of anthropogenic ...

Long-snouted seahorse, Hippocampus guttulatus, under global warming
Costa, Ana B.; Correia, Miguel; Silva, Goncalo; Faria, Ana M.The earth’s climate system and the global ocean have been warming up, since the mid-twentieth century and it is expected that the global and ocean´s temperature will rise in the next years even more [1,2,13,25,28]. For ectotherms, such as fish, temperature is a determinant cue for several behavioural [29], physiological [24], and metabolic processes [6]. Seahorses’ particular life history makes them vulnerable ...
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...
