... These diameters were selected because ichthyocarbonates <0.36 mm (∼50% of global production) were predicted to fully dissolve before reaching a water depth of 500 m when excretion is assumed to occur in the surface waters of the ocean . Particles with diameters greater than 0.91 mm (∼25% of global production; Folkerts et al., 2024) were predicted to reach oceanic depths greater than 1,000 m, where millennial scale sequestration is thought to be achieved (Bianchi et al., 2021). Through this approach, both the measured dissolution rates as well as the diminishing size of ichthyocarbonate with depth occurring as a function of dissolution were used to estimate complete dissolution depths. ...

... Wildlife populations, including aquatic species, are continually exposed to seasonal environmental changes that affect their physiology and behavior [1]. Teleost fish play vital roles in aquatic ecosystems by contributing to nutrient cycling, energy flow, and biogeochemical processes, such as carbon [2][3][4] and nitrogen [5,6] cycling, which influence nutrient availability and ecosystem productivity. As key predators and prey within aquatic food webs, they help regulate the population sizes of other organisms, maintaining Life 2024, 14, 1273 2 of 24 ecological balance [7]. ...

... Recent work on O. beta has focused on describing the monoaminergic system, with a particular emphasis on serotonin and the role it plays controlling vascular resistance and blood flow [26,27]. Multiple labs have successfully bred O. beta in a laboratory setting [28]. This provides the opportunity for siblings to be used in physiological studies reducing inter-individual variation, and for families to be used for examination of trait heritability, ontogenetic adaptations, and in trans-generational studies, expanding their potential as model organisms. ...

... However, a recent study of dissolution rates of ichthyocarbonate produced by three marine fish species conducted across a range of aragonite saturation indicated heterogeneous dissolution rates unrelated to mol%MgCO 3 . Thus, alternative controls on the ichthyocarbonate dissolution rate, such as organic matter coatings and the presence of microbial communities, were hypothesized to play more important roles in the fate of ichthyocarbonate Grosell & Oehlert, 2023). ...

... The significance of substantially reducing fishing levels to guarantee the sustainability of this species was underscored by the study. The study conducted by (Kim & Na, 2022) underscored the detrimental effects of overfishing on the populations of yellowfin tuna in the Indian Ocean and bigeye tuna in the Atlantic (Heuer et al., 2023). There is an urgent need to address this condition in order to reduce the negative repercussions of overfishing. ...

... The authors identified changes in speed, distance moved, burst movements, and acceleration as the drivers of increased predation in those studies, rather than cardiorespiratory/swim performance impairments. Wild adult mahi-mahi (Coryphaena hippurus) experimentally exposed to crude oil and released back into the Gulf of Mexico with electronic tags were distributed deeper and cooler water during nighttime hours than control fish (Schlenker et al., 2022), a behavior hypothesized to be a protective mechanism to accommodate the additive effects of temperature and oil exposure that decrease aerobic scope in the laboratory (Schlenker et al., 2022;Ackerly and Esbaugh, 2021). Like laboratory studies on red drum, wild mahi-mahi exposed to oil and at liberty in the Gulf of Mexico showed more frequent bursts of acceleration compared to control fish (Schlenker et al., 2022). ...

... Some previous studies with fish, invertebrates, and human liver spheroids have reported an increase in biological potency as a function of increasing chain length (Gebreab et al., 2020(Gebreab et al., , 2022Kadlec et al., 2023;Reardon et al., 2021). At the level of the whole-body reduced transcriptome response in larval fathead minnows, there was a statistically significant negative correlation (Pearson r = -0.52, ...

... The basic mechanistic elements underlying the system of β-NHE short-circuiting in teleosts are: (i) a pH-sensitive Hb; (ii) RBC pH i regulation by β-NHE; and (iii) the presence of paCA at the sites of O 2 unloading. The first two requirements appear to be met in several migratory salmonids (Shu et al. 2017), other marine teleosts (Shu et al. 2021) and more generally in a broad representation of the teleost clade (Berenbrink et al. 2005). However, exceptions are found in the siluriformes, Apteronotus, Anguilla, Monopterus, Botia and Misgurnus that have reduced or absent β-NHE activities compared to other teleosts. ...

... One recent example of a potential additional adaptation to avoid damage is the variable buoyancy in eggs of several species that reproduce in oceanic surface waters (Fig. 10). The embryos sank down to greater depths when exposed to UV-A radiation and recovered a surface position when released from UV-stress [278,279]. Although the response is induced by UV-A irradiation, in the ocean this mechanism would concomitantly reduce exposure to solar UV-B radiation. ...

... Сырая нефть представляет собой сложную смесь углеводородных и неуглеводородных соединений, однако полициклические ароматические углеводороды (ПАУ) считаются особенно токсичными компонентами [62,63]. Было показано, что воздействие ПАУ, полученного из сырой нефти, вызывает нарушение метаболических функций и способности плавать, а также морфологические дефекты, кардиотоксичность, замедление роста и повышенную смертность на ранних стадиях жизни морских рыб и беспозвоночных [64]. ...
