Prolonged exposure to elevated temperature leads to severe thermal stress in th...

Changes in water temperature may have profound effects on phy-siology, metabolism, and fish behaviour. However, much of theexisting research is based on relatively short-term experiments. Inthe context of climate change, where water temperatures areincreasing seasonally, and the frequency and duration of extremeheatwave events are rising, incorporating longer exposure periodswill provide a better understanding ...

Passive tobacco smoke exposure and children’s health outcomes: a preliminary an...

Background: Children’s exposure to Passive Tobacco Smoke (PTS) in utero and during infancy can increase the risk of childhood respiratory diseases and infections (e.g., otitis) [1-3]. Objective: This study explores the association between children’s exposure to PTS in utero (maternal, frequent smoking family member during pregnancy), up to one year, and current maternal smoke exposure with, to date, and the fir...

Evidence on the relationship between airborne exposure to endocrine-disrupting ...

Background: Evaluating airborne exposure to endocrine-disrupting chemicals (EDCs) in children is paramount, given their vulnerability, which can lead to enduring health impacts such as asthma-related outcomes [1]. Objective: This systematic review aims to identify existing scientific evidence assessing airborne exposure to EDCs among school-age children and asthma onset or exacerbation. Methods: This review adh...

Performance of the long-snouted seahorse, Hippocampus guttulatus, under warming...

Temperature is a determinant cue for several behavioral, physiological, and metabolic processes in fish, which occur within a range set to optimize species fitness. Understanding how ocean warming will impact species, at individual and population levels, is, therefore, of utmost relevance for management and conservation purposes. This knowledge assumes particular relevance when it comes to species with unique l...

Impact of anthropogenic noise on the survival and development of meagre (Argyro...

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 ...

Differential effects of food restriction and warming in the two-spotted goby: i...

Climate 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...

Reproductive trade-offs in a temperate reef fish under high pCO2 levels

Fishes 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...

The impact of climate change on the ecology and dynamics of change of small pel...

Sand smelt ability to cope and recover from ocean's elevated CO2 levels

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

The 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...
