Thermal bottlenecks in the life cycle define climate vulnerability of fish

Published: July 2, 2020

Some cope better than others Increasingly, research is revealing how organisms may, or may not, adapt to a changing climate. Understanding the limitations placed by species's physiology can help determine whether it has an immediate potential deal with rapid change. Many studies have looked at physiological tolerance climate change in fishes, results indicating range of responses. Dahlke et al. conducted meta-analysis explore life stage influence ability tolerate temperature (see Perspective Sunday). They found that embryos and breeding adult fishes are much more susceptible those other stages this factor must therefore be considered evaluations susceptibility.

From gametogenesis to spawning: How climate‐driven warming affects teleost reproductive biology

Journal of Fish Biology, Journal Year: 2020, Volume and Issue: 97(3), P. 607 - 632

Published: June 21, 2020

Abstract Ambient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the function of fish, which has implications for wild population dynamics, fisheries and aquaculture. In this extensive review spanning tropical cold‐water environments, we examine higher‐than‐optimal temperatures on teleost development physiology across stages, species, generations sexes. doing so, demonstrate that warmer‐than‐optimal can affect every stage from puberty through act spawning, these responses are mediated by age at spawning associated with changes multiple levels brain–pituitary–gonad axis. Response often species‐specific environmental history/transgenerational conditioning, amplitude, timing duration thermal exposure within a generation. Thermally driven physiology, gamete maturation typically culminate poor sperm oocyte quality, and/or advancement/delay/inhibition ovulation/spermiation spawning. Although field reproduction advanced many respects, identify areas where research lacking, males egg quality “omics” perspectives.

Avenues of reef-building coral acclimatization in response to rapid environmental change

Journal of Experimental Biology, Journal Year: 2021, Volume and Issue: 224(Suppl_1)

ABSTRACT The swiftly changing climate presents a challenge to organismal fitness by creating mismatch between the current environment and phenotypes adapted historic conditions. Acclimatory mechanisms may be especially crucial for sessile benthic marine taxa, such as reef-building corals, where change factors including ocean acidification increasing temperature elicit strong negative physiological responses bleaching, disease mortality. Here, within context of multiple stressors threatening organisms, I describe wealth metaorganism response rapid ontogenetic shifts in organism interactions with that can generate plasticity. then highlight need consider evolutionary an adaptive (epi)genetic continuum. Building on definitions these continuum, also present how interplay microbiome, epigenetics parental effects creates additional avenues acclimatization. To under what conditions epigenetic inheritance has more substantial role, propose investigation into offset timing gametogenesis leading different environmental integration times eggs sperm consequences this gamete compatibility. Collectively, non-genetic, yet heritable phenotypic plasticity will have significant ecological implications persistence change. As such, corals ideal time-sensitive models further development our understanding feedback loops multi-player

Synthesis of Thresholds of Ocean Acidification Impacts on Echinoderms

Frontiers in Marine Science, Journal Year: 2021, Volume and Issue: 8

Published: May 19, 2021

Assessing the vulnerability of marine invertebrates to ocean acidification (OA) requires an understanding critical thresholds at which developmental, physiological, and behavioral traits are affected. To identify relevant for echinoderms, we undertook a three-step data synthesis, focused on California Current Ecosystem (CCE) species. First, literature characterizing echinoderm responses OA was compiled, creating dataset comprised >12,000 datapoints from 41 studies. Analysis this set demonstrated related physiology, behavior, growth development, increased mortality in larval adult stages low pH exposure. Second, statistical analyses were conducted selected pathways specific duration, taxa, depth-related life stage. Exposure reduced led impaired across range endpoints both stages. Third, through discussions expert panel identified eight duration-dependent, stage, habitat-dependent assigned each confidence score based quantity agreement evidence. The these effects ranged within 7.20 7.74 duration 7 30 days, all characterized with either medium or confidence. These yielded risk early warning lethal impacts, providing foundation consistent interpretation monitoring numerical model simulations support climate change assessments evaluation management strategies. As demonstration, two applied CCE visualize current state conditions potential habitat.

Crown of thorns starfish life-history traits contribute to outbreaks, a continuing concern for coral reefs

Emerging Topics in Life Sciences, Journal Year: 2022, Volume and Issue: 6(1), P. 67 - 79

Crown of thorns starfish (COTS, Acanthaster sp.) are notorious for their destructive consumption coral that decimates tropical reefs, an attribute unique among marine invertebrates. Their populations can rapidly increase from 0-1 COTS ha-1 to more than 10-1000 in short order causing a drastic change benthic communities and reducing the functional species diversity reef ecosystems. Population outbreaks were first identified be significant threat reefs 1960s. Since then, they have become one leading causes loss along with bleaching. Decades research investment Australia elsewhere, particularly Japan, been directed towards identifying, understanding, managing potential designing population control methods. Despite this, drivers remain elusive. What is becoming increasingly clear success tied inherent biological traits, especially early life. Survival larval juvenile likely enhanced by dietary flexibility resilience variable food conditions as well phenotypically plastic growth dynamics, all magnified extreme reproductive COTS. These traits enable capitalise on anthropogenic disturbances systems endure less favourable conditions.
