Article
Climate warming is causing rapid spatial expansion of ocean warm pools from equatorial latitudes towards the subtropics. Sedentary coral reef inhabitants in affected areas will thus be trapped in high temperature regimes, which may become the “new normal”. In this study, we used clownfish Amphiprion ocellaris as model organism to study reef fish me...
Article
Predicting responses of marine organisms to global change requires eco-physiological assessments across the complex life cycles of species. Here, we experimentally tested the vulnerability of a demersal temperate fish (Sparus aurata) to long-lasting heatwaves, on larval, juvenile and adult life-stages. Fish were exposed to simulated coastal (18 °C)...

Abstract Iodine is an essential element required for the synthesis of thyroid hormones. Its deficiency is correlated to goiter, while in excess can cause autoimmune thyroiditis. Worldwide exists a deficiency in iodine, and recommended daily intake should be 150μg for adults. One of the most naturally available and abundant resources of iodine is ma...
Article
The ability of intertidal organisms to maintain their performance via molecular and physiological adjustments under low tide, seasonal fluctuations and extreme events ultimately determines population viability. Analyzing this capacity in the wild is extremely relevant since intertidal communities are under increased climate variability owing to glo...

Climate warming is causing the rapid expansion of tropical warm pools in the oceans at rates exceeding 2 million square kilometers per decade. This phenomenon is leading to increasingly larger ocean areas delimited by high temperature isotherms, especially in the range between 29˚C and 30˚C. From an ecological perspective, this means that marine an...

Current climate warming trends call for continuous biomonitoring of thermal stress in situ in tropical areas. The categorization and mapping of vulnerable species and prioritization of conservation actions are essential for the maintenance of functional biodiversity in these habitats. However, a lack of integrative approaches addressing thermal com...
Article
Sharks have been facing unprecedented pressure over the last decades, and ocean acidification may represent an additional threat, particularly during their most susceptible life stages. Hence, the present study aimed to investigate the effects of ocean acidification (control pCO 2 ~ 400 μatm; high pCO 2 ~ 900 μatm) on the growth, swimming performan...

Climate change, particularly ocean warming, is thought to benefit the spread of invasive species due to their increased tolerance to temperature fluctuations when compared to native species. However, the physiological tolerance of invasive species as a potential mechanism driving invasion success has been overlooked. Here, we experimentally evaluat...
Article
Extreme events associated with global warming, such as ocean heat waves, can have contrasting fitness consequences for different species, thereby modifying the structure and composition of marine communities. Here, we examined the effects of a laboratory simulated heat wave on the physiology and performance of two Indo-Pacific crustacean species: t...
Article
Currently, the effects of global warming on marine organisms are widely recognized by the scientific community. However, studies that relate the increase in ocean temperature with other stress factors are still scarce. The main aim of this study was to evaluate the effects of water temperature increase on the parasite Anilocra frontalis, the parasi...

According to climate science, ocean warming is one of the current and future greatest threats to coastal ecosystems. Projection scenarios for the end of this century show that tropical intertidal ecosystems are particularly at risk. In this study we optimized and tested a holistic method for bio-monitoring present and projected thermal pressure in...

Knowledge of thermal stress biology for most tropical fish species in reef ecosystems under climate change is still quite limited. Thus, the objective of this study was to measure the time-course changes of thermal stress biomarkers in the commercially exploited coral reef fish Amphiprion ocellaris, during a laboratory simulated event of increased...
Article
Global change is impacting aquatic ecosystems, with high risks for food production. However, the molecular underpinnings of organismal tolerance to both ocean warming and acidification are largely unknown. Here we tested the effect of warming and acidification in a 42-day experiment on a commercial temperate fish, the gilt-head seabream Sparus aura...

Article
Atmospheric 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...

Tropical and subtropical reef associated organisms have been recognized as being among the most vulnerable organisms towards environmental change, namely due to extreme climatic events associated with global warming. The study of their physiological responses under environmental stress seems to be a key issue for assessing ecosystem health in these...

The presence of antidepressants, such as venlafaxine (VFX), in marine ecosystems is increasing, thus, potentially posing ecological and human health risks. The inherent mechanisms of VFX uptake and elimination still require further understanding, particularly accounting for the impact of climate change-related stressors, such as warming and acidifi...

The mode of action for nanoparticle (NP) toxicity in aquatic organisms is not yet fully understood. In this work, a strategy other than toxicity testing was applied to Daphnia magna exposed to TiO2-NPs: the use of nuclear microscopy and the assessment of protein profile. D. magna is a keystone species broadly used as a model system in ecotoxicology...
Article
Animal physiology and ecology are affected by increasing environmental temperatures, and this is particularly relevant in the tropics, where organisms are already living on the warm edge of their thermal windows. Here, we present data on sub-lethal effects of temperature (using molecular biomarkers), thermal tolerance, warming safety margins and bo...

Introduction: The increase in gas emissions (e.g. CO2) results in temperature increase on a global scale. Models projections predict a sea surface temperature to increase by 1–4 ºC [1]. Thus, the main objective of this study is to evaluate the vulnerability of the tropical coral species Galaxea fascicularis and Montipora capricornis to long-term te...

Sharks 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 (C...

Introduction: The increase in gas emissions, namely CO2, from anthropogenic sources results in temperature increase on a global scale. However, absorption of CO2 by the oceans results also in increased ocean acidity, decreasing the ocean’s capacity to absorb additional atmospheric CO2, which implies that future emissions will lead to an inevitable...

Climate warming presents new challenges for environmental biomonitoring. There is a need for the development of biomarkers that respond not only to chemical pollution but also to thermal stress events.

During wine fermentations Saccharomyces cerevisiae starts to excrete into the growth medium antimicrobial peptides (AMPs) that induce death of non-Saccharomyces yeasts at the end of exponential growth phase (24-48 h). Those AMPs were found to derive from the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH). On the other hand, the...
