PolyQ Length of the Clock Gene Is Correlated With Pelagic Larval Duration in the Damselfishes (Pomacentridae), but Within a Species Habitat Availability Counts

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(4)

Published: April 1, 2025

ABSTRACT Immediately after hatching, larvae of coral reef fish leave their natal environment and begin pelagic larval phase probably to avoid high predation on the reef. The time they spend in open ocean (pelagic duration, PLD), before settlement varies from species depends partly developmental processes that eventually require re‐settlement a polyglutamine region (PolyQ) as part clock gene has been suggested possible candidate could control potentially until settlement, which can be determined by counting rings otoliths. We studied potential relationship between number glutamine repeats 20 pomacentrids PLDs. Most came similar locations, so we avoided impact latitudinal clines PLD. Within gene, found two main distinguishable, variable glutamine‐rich regions (PolyQ Qrich). Considering phylogenetic relationships, PolyQ/Qrich repeat length duration were significantly positively correlated. However, when analyzing this single species, neon damselfish ( Pomacentrus coelestis ), did not find significant correlation PolyQ variation Instead, reduction PLD years with increased habitat availability. Our results show influence timing broader scale, but ecological factors—such availability—can also have impact.

Physiological Traits for Predicting Poleward Extensions in Tropical Fishes: From Lab to Management

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(4)

Published: April 1, 2025

ABSTRACT Tropicalization, the phenomena by which tropical organisms are extending their distributions poleward into temperate latitudes in response to increasing temperatures and strengthening boundary currents, is occurring globally. Vagrant species have large ecological economic ramifications for habitats they invade. However, not all vagrants able persist long term habitats, with first winter being a potential bottleneck persistence. This brings question how some vagrant successful at surviving conditions physiology underpinning this success. provides opportunity only look available data introspectively but also forward‐thinking applying range of holistic physiological traits relevant biology management. Therefore, aim our review twofold: current state‐of‐knowledge mechanisms tropicalization develop framework practices can complement new perspectives tools. We use range‐expanding reef fishes as model group over 100 undergoing climate‐driven shifts eastern Australia case‐study location due it primary focal “living laboratory” understanding dynamics since early 2000s. Current studies suggest that diet, behavior, metabolic trade‐offs may explain fish persistence, these focus on whole‐animal traits. Our helps expand upon traits, life stages, experimental design, (e.g., we highlight value genetic cellular markers pathway changes under cold stress biomarkers) improve tropicalization. Taken together, places emphasis measuring suite complimentary from whole‐animal, help guide future predictions long‐term persistence habitats.

The influence of habitat association on swimming performance in marine teleost fish larvae

Fish and Fisheries, Journal Year: 2021, Volume and Issue: 22(6), P. 1187 - 1212

Published: June 21, 2021

Abstract Latitude and body size are generally considered key drivers of swimming performance for larval marine fishes, but evidence suggests that evolutionary relationships habitat may also be important. We used a comparative phylogenetic framework, data synthesis case study approach to investigate how differs among larvae fish species across latitude. First, we investigated changed with length, found temperate reef fishes have the greatest increases in length. Secondly, compared differences three metrics (critical speed, situ swimming, endurance) post‐flexion larvae, whilst considering morphology, higher capacity than non‐reef (pelagic demersal) which is likely due larger, more robust sizes. Thirdly, late‐stage tropical oceanographic better understand ecological relevance their high‐capacity swimming. high grow larger suggest pressures find specific, patchily distributed upon settle. Given current bias towards studies on percomorph at low latitudes, highlight there need research other lineages from latitudes. Overall, our findings provide valuable context morphological traits important dispersal recruitment processes selected teleost larvae.

Measurement of swimming ability in larval marine fishes: comparison of critical speed with in situ speed

Marine Ecology Progress Series, Journal Year: 2020, Volume and Issue: 650, P. 203 - 215

Published: Feb. 6, 2020

For much of their pelagic larval dispersal (PLD) stage, perciform fishes are able to directly influence by horizontal swimming, but it is unclear which means measuring swimming ability most appropriate for modelling and studying demographic genetic connectivity. Most studies use critical speed (Ucrit), a laboratory flume measure derived increasing flow until larvae can no longer maintain position. data on fish Ucrit, usually nearing the end PLD. Recognizing that forced inappropriate dispersal, researchers have used decreased Ucrit values, 50%, argued strongly correlated with more relevant measures. Here I examined suitability versus in situ (ISS), wherein measured divers following them ocean meter. Considerations require inclusion ontogeny. Swimming regressions size 10 species 8 families showed ISS not well correlated. The Ucrit:standard length (SL) slope was greater than ISS:SL 6 species, did differ other 4 species. No overall metric, e.g. X % = ISS, conversion ISS. Conversion straightforward. measures potential, what do ocean, whereas ocean. ontogeny less variable, dispersal. may be useful purposes.

Abstract Fish swimming capacity is a key life history trait critical to many aspects of their ecology. U-crit (critical) speeds provide robust, repeatable relative measure speed that can serve as useful surrogate for other measures performance. Here we collate and make available one the most comprehensive datasets on abilities tropical marine fish larvae pelagic juveniles, which are reef associated adults. The dataset includes measurements settlement stage fishes across large range species families obtained mostly from field specimens collected in light traps crest nets; development throughout ontogeny using reared larvae. In nearly all instances, size individual was available, cases, data include morphological (e.g. “propulsive area”) predicting capacity. We hope these prove further studies larval performance broader syntheses.
