Elevated carbon dioxide (CO(2)) has recently been shown to affect chemosensory and auditory behaviour, activity levels of larval reef fishes, increasing their risk predation. However, the mechanisms underlying these changes are unknown. Behavioural lateralization is an expression brain functional asymmetries, thus provides a unique test hypothesis that elevated CO(2) affects function in fishes. We tested effect near-future concentrations (880 µatm) on behavioural fish, Neopomacentrus...

Rising CO2 levels in the oceans are predicted to have serious consequences for many marine taxa. Recent studies suggest that non-genetic parental effects may reduce impact of high on growth, survival and routine metabolic rate fishes, but whether environment mitigates behavioural sensory impairment associated with remains unknown.

Recent research has shown that exposure to elevated carbon dioxide (CO2) affects how fishes perceive their environment, affecting behavioral and cognitive processes leading increased prey mortality. However, it is unclear if mortality results from changes in the dynamics of predator-prey interactions or due increasing activity levels. Here we demonstrate ocean pCO2 projected occur by 2100 significantly effects a pair common reef fish: planktivorous damselfish Pomacentrus amboinensis...

Coral reefs are degrading globally due to increased environmental stressors including warming and elevated levels of pollutants. These affect not only habitat-forming organisms, such as corals, but they may also directly the organisms that inhabit these ecosystems.

Microorganisms quickly colonise microplastics entering the ocean, forming a biofilm that, if ingested, is consumed with microplastics. Past research often neglects to expose fish biofouled microplastics, opting only for clean despite low likelihood that will encounter Here, we investigate physiological impacts of polyethylene microplastic (300–335 μm) exposure in juvenile fish. Intermittent flow respirometry, antioxidant enzyme activity, and lipid peroxidation were investigated after exposed...

Many vertebrates are known to show behavioural lateralization, whereby they differentially use one side of their body or either bilateral organs limbs. Behavioural lateralization often manifests in a turning bias fishes, with some individuals showing left and others right bias.

Ocean acidification and warming, driven by anthropogenic CO 2 emissions, are considered to be among the greatest threats facing marine organisms. While each stressor in isolation has been studied extensively, there less focus on their combined effects, which could impact key ecological processes.

Abstract The reproductive success of marine ectotherms is especially vulnerable in warming oceans due to alterations adult physiology, as well embryonic and larval survival prospects. These vital responses may, however, differ considerably across the species' geographical distribution. Here we investigated life history, focusing on ecology, three spatially distant populations (stocks) Atlantic cod ( Gadus morhua , Gadidae) (50–80° N), Irish/Celtic Seas‐English Channel Complex, North Barents...

Summary Behavioural lateralization – the preferential use of one side body or either bilateral organs limbs has been well documented in many species, a number contexts. While benefits reported are numerous, existing latent variability degree within and across populations, species taxa indicates that costs may modulate its expression. Few studies have changes at individual level, response to long‐term environmental conditions, but not short‐term conditions. Predation is highly variable both...

Abstract Habitat degradation not only disrupts habitat‐forming species, but alters the sensory landscape within which most species must balance behavioural activities against predation risk. Rapidly developing a cautious phenotype, condition known as neophobia, is advantageous when entering novel risky habitat. Many aquatic organisms rely on damage‐released conspecific cues (i.e. alarm cues) an indicator of impending danger and use them to assess general risk develop neophobia. This study...
