“…Several recent articles have reviewed evidence that higherthan-optimal temperatures can alter HPG axis regulation of gametogenesis in fishes [14,[16][17][18]54], so only an abbreviated summary is provided here. For sexually mature females, high temperatures inhibit oogenesis via endocrine changes across multiple tissues: the brain/pituitary gland, the ovary and the liver.…”

“…lower ovarian gonadotropin receptor expression) as well as reduced expression of steroidogenic enzymes. including Cyp19a1a [14,[16][17][18][54][55][56]. Elevated temperature downregulation of steroidogenesis leads to lower circulating E 2 (similar to high temperature-induced masculinization; see §2a), which diminishes vitellogenin and choriogenin synthesis by the liver [55,56], impairs secondary/vitellogenic oocyte growth and chorion formation, and, ultimately, results in fewer or smaller eggs and lower egg viability [14].…”

“…In tropical species, lunar cycles or water flow changes across wet and dry seasons of precipitation may be foremost factors synchronizing gametogenesis and spawning [50,52]. Even so, temperature still affects reproduction in many tropical fishes, and some tropical species may actually live closer to their upper thermal limits for reproduction, given the narrower temperature ranges these species typically experience [53,54].…”

Reproduction in fishes is sensitive to temperature. Elevated temperatures and anomalous ‘heat waves’ associated with climate change have the potential to impact fish reproductive performance and, in some cases, even induce sex reversals. Here we examine how thermal sensitivity in the hormone pathways regulating reproduction provides a framework for understanding impacts of warmer conditions on fish reproduction. Such effects will differ depending on evolved variation in temperature sensitivity of endocrine pathways regulating reproductive processes of sex determination/differentiation, gametogenesis and spawning, as well as how developmental timing of those processes varies with reproductive ecology. For fish populations unable to shift geographical range, persistence under future climates may require changes in temperature responsiveness of the hormone pathways regulating reproductive processes. How thermal sensitivity in those hormone pathways varies among populations and species, how those pathways generate temperature maxima for reproduction, and how rapidly reproductive thermal tolerances can change via adaptation or transgenerational plasticity will shape which fishes are most at risk for impaired reproduction under rising temperatures. This article is part of the theme issue ‘Endocrine responses to environmental variation: conceptual approaches and recent developments’.

“…indicate that this landscape could be modified with global change, as indicated by i) behavioral experiments showing that anemonefish juveniles can discriminate between olfactive cues emanating from bleached and unbleached host anemones , and ii) the fact that some chemical cues degrade more quickly in conditions simulating global change (UV radiation and ocean acidification) compared to control conditions . Therefore, modifications of the olfactive landscape could lead to misinterpretations by anemonefish larvae of the location of their settlement site or their ability to escape predation Biswal et al 2021).…”

Anemonefishes, one of the most popular and recognizable fishes in the world, are much more than film characters; they are also emerging model organisms for studying the biology, ecology, and evolution of coral reef fishes. They are a group of 28 species often employed to study patterns and processes of social organization, intra-and inter-specific competition, sex change, mutualism, dispersal and connectivity of fish populations, habitat selection, pigment pattern formation, lifespan, and predator-prey interactions. This multi-authored book covers all these areas and provides an update on the research done with this model and the perspective it opens for the future. Key Features• Contains basic and up-to-date information on an emerging fish model • Allows non-specialist readers to grasp the relevance of a wide research area Cover photo: OIST/Kina Hayashi 林希奈 Licensed under CCBY4.0 (attribution) First edition published 2023 by CRC Press
