“…Because fish were of similar body length and mass (Table S3), there was most likely a change in body shape. However, the magnitude of this change differed between T E groups, in accordance with previous observations that T E affects body shape (20). The different responses to cold were reflected by significant T A × T E interactions for total muscle area and the total transverse area of fast fibers (P = 0.006 and P = 0.040) and by the cold-induced increases in total muscle, slow fiber, and fast fiber transverse areas in only the 22°C and 32°C T E groups.…”

Global warming is intensifying interest in the mechanisms enabling ectothermic animals to adjust physiological performance and cope with temperature change. Here we show that embryonic temperature can have dramatic and persistent effects on thermal acclimation capacity at multiple levels of biological organization. Zebrafish embryos were incubated until hatching at control temperature (T E = 27°C) or near the extremes for normal development (T E = 22°C or 32°C) and were then raised to adulthood under common conditions at 27°C. Short-term temperature challenge affected aerobic exercise performance (U crit ), but each T E group had reduced thermal sensitivity at its respective T E . In contrast, unexpected differences arose after long-term acclimation to 16°C, when performance in the cold was ∼20% higher in both 32°C and 22°C T E groups compared with 27°C T E controls. Differences in performance after acclimation to cold or warm (34°C) temperatures were partially explained by variation in fiber type composition in the swimming muscle. Cold acclimation changed the abundance of 3,452 of 19,712 unique and unambiguously identified transcripts detected in the fast muscle using RNA-Seq. Principal components analysis differentiated the general transcriptional responses to cold of the 27°C and 32°C T E groups. Differences in expression were observed for individual genes involved in energy metabolism, angiogenesis, cell stress, muscle contraction and remodeling, and apoptosis. Therefore, thermal acclimation capacity is not fixed and can be modified by temperature during early development. Developmental plasticity may thus help some ectothermic organisms cope with the more variable temperatures that are expected under future climate-change scenarios.environmental physiology | fish | muscle transcriptome | functional genomics | high-throughput sequencing T emperature has profound effects on the physical and chemical processes that dictate how biological systems function. Ectothermic organisms-those that cannot regulate body temperature using endogenous heat production-are particularly susceptible to changes in environmental temperature. Species and populations can typically survive and perform across a finite range of temperatures, the breadth of which is a critical determinant of their distribution and abundance (1, 2). The physiological and molecular mechanisms underlying how ectotherms perform when faced with daily and seasonal temperature variation have attracted significant attention for decades, and this interest has intensified in an attempt to understand the potential ecological impacts of global climate change (3, 4). It is clear that temperature acclimatization can shift thermal optima and performance breadth (5), which may increase fitness and improve the viability of populations during warming (6-8). However, much of what we know about the integrative mechanisms for this ability comes from studies of juvenile and adult animals. There has been relatively little emphasis on how interactions between temperature and ...

“…In spite of its popularity as a research tool, only recently did some integrated studies about its biological and ecological characteristics emerge (Engeszer et al 2007;Spence et al 2008) which however do not complete the puzzle of knowledge regarding its early life conditions and especially the environmental temperature. Although the temperature of the species' habitat seems to be established at the range from 6°C in the winter up to 38°C in the summer (Spence et al 2008) there are still some contradictions concerning the temperature range in which reproduction and early development take place (Sfakianakis et al 2011). Our personal observations throughout many rearing trials showed that the rearing temperatures of 22°C and 31°C are the lower and upper limit values respectively for successful rearing in the laboratory.…”

Although zebrafish (Danio rerio) is a highly studied organism on many fields of research, many aspects of its basic biology still elude the scientific community. Its response to temperatureespecially developmental one -has been very scarcely studied and this is an important lack of knowledge since the species is considered quite eurythermal in nature. In the present study, zebrafish was subjected to four different developmental temperatures (22, 25, 28 and 31°C) from the half-epiboly stage until after metamorphosis in order to examine whether the temperature can influence the juvenile's phenotype. Morphometric and meristic characters were explored. Body shape and almost all of the meristic characters studied were significantly affected by the temperature applied during the first stages of development. Most meristic characters of the study, presented a significant differentiation in the extreme temperatures used (22 and/or 31°C), whereas lower temperatures seemed to produce higher meristic counts in the majority of the characters. Zebrafish juveniles, as shown in this study, exhibit highly variable phenotypes (phenotypic plasticity) induced by diverse thermal conditions during their early ontogenetic stages possibly in order to successfully adjust to different environments.

“…These findings are in juxtaposition to previous findings on the effects of developmental temperature on aerobic performance in zebrafish. Sfakianakis et al () found that zebrafish reared at four different temperatures (22°C, 25°C, 28°C, and 31°C) had differential sustained aerobic swim performance when acclimated to one common median temperature (26°C). Individuals reared at 22°C had lower average relative critical swim speeds ( RU crit ) than those reared at the three higher temperatures, although the only significant difference seen was at 31°C (Sfakianakis et al, ).…”

Fishes are particularly sensitive to the effects of environmental conditions during early development, which can significantly impact adult morphology, performance, and survival. Previous research has highlighted the sensitivity of fishes to the effects of temperature during early development on vertebral number and muscle composition, which are both important determinants of an individual's swimming performance. In this study, we investigated the effect of developmental temperature on vertebral and muscle variation, and the subsequent effect of any variation on burst swimming performance in zebrafish (Danio rerio). Following development at a range of temperatures, all individuals were shifted to and maintained at a common temperature before startle responses were recorded and individuals were analyzed for either vertebral number or muscle composition. Our results indicate that developmental temperature does not significantly affect muscle composition, but can affect an individual's vertebral number, and that individuals with more vertebrae achieved greater displacement and velocities during C-start performance. To determine the ecological importance of this vertebral variation and to identify the potential selective factors behind it, we exposed populations of zebrafish with various vertebral numbers to native predators, needlenose garfish (Xenentodon cancila). We found that only caudal vertebral number was related to survival, and that survivors had the same caudal vertebral number across developmental temperatures. Overall, this work highlights the importance of including variation in musculoskeletal anatomy when investigating what is driving selection in fishes. J. Exp.
