Developmental environments do not affect thermal physiological traits in reptiles: an experimental test and meta-analysis

Biology Letters, Journal Year: 2023, Volume and Issue: 19(5)

Published: May 1, 2023

On a global scale, organisms face significant challenges due to climate change and anthropogenic disturbance. In many ectotherms, developmental physiological processes are sensitive changes in temperature resources. Developmental plasticity thermal physiology may provide adaptive advantages environmental extremes if early conditions predictive of late-life environments. Here, we conducted laboratory experiment test how maternal resource investment influence traits (critical maximum: CT max preference: T pref ) common skink ( Lampropholis delicata ). We then compared our experimental findings more broadly across reptiles (snakes, lizards turtles) using meta-analysis. both study meta-analysis, did not find evidence that environments or . Furthermore, the effects on vary by age, taxon zone (temperate/tropical). Overall, magnitude appears be limited reptile taxa suggesting behavioural evolutionary important. However, there is paucity information most taxa, broader focus performance curves themselves will critical understanding impacts changing future.

Evolutionary adaptation under climate change: Aedes sp. demonstrates potential to adapt to warming

Proceedings of the National Academy of Sciences, Journal Year: 2025, Volume and Issue: 122(2)

Published: Jan. 7, 2025

Climate warming is expected to shift the distributions of mosquitoes and mosquito-borne diseases, promoting expansions at cool range edges contractions warm edges. However, whether mosquito populations could maintain their through evolutionary adaptation remains unknown. Here, we investigate potential for thermal in Aedes sierrensis , a congener major disease vector species that experiences large gradients its native range, by assaying tolerance prolonged acute heat exposure, genetic basis diverse, field-derived population. We found pervasive evidence heritable variation tolerance, phenotypic trade-offs versus exposure. Further, genomic associated with was clustered several regions genome, suggesting presence larger structural variants such as chromosomal inversions. A simple model based on our data estimates maximum rate will exceed projected climate warming, implying track via adaptation.

Reflections on the Role of Differentiation Processes in Forming Behavioral Phenotypes: Can These Processes Replace the Concepts of Plastic Phenotype and Reversible Plastic Phenotype?

Biology, Journal Year: 2025, Volume and Issue: 14(2), P. 187 - 187

This essay presents two lines of argument to suggest that the extension into adulthood specific phenotypic differentiation processes, typical early development, is fundamental evolution cognition. The first these organized in three steps. step reviews various studies human highlighting it has slowed down throughout compared great apes. second explores relationship between this development and third discusses evolutionary comparative analyses show a correlation cognitive processes developmental changes. line examines concepts phenotype. First, phenotype are reviewed correspondence meanings word plasticity (i.e., as ability alternate or shape), concluded all phenotypes -rigid, plastic, reversible-fit meaning shaping. It proposed phenotypical process can be seen continuous series functional differentiations occur at different times during life organism contextual points, both inside outside organism. Finally, brief recapitulation presented focused on supporting formation behavioral sequence shaping environmental interactions from most general particular.

Transcriptome analyses reveal differences in the response to temperature in Florida and Northern largemouth bass (Micropterus spp.) during early life stages

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(2), P. e0317563 - e0317563

Published: Feb. 18, 2025

Temperature is one of the most relevant factors influencing development aquatic species, making it a key parameter to consider for aquaculture. Largemouth bass (LMB; Micropterus spp .) are highly human consumption and sport fishing, representing North America’s important freshwater fisheries. Yet, questions remain on how LMB raised in recirculating aquaculture systems (RAS) respond different temperatures. The main objective this study was determine impact thermal rearing conditions (21°C, 24°C, 27°C) gene expression Florida Northern larvae at 8- 28-days post hatch (DPH). Using de novo transcriptomes as reference, our results suggest that differences were mostly associated with temperature, while controlled by temperature developmental stage. In general, both lineages showed activation molecular pathways growth, such muscle, nervous system, vascular system. There signatures stress warming well, including immune function, apoptosis, regulation inflammation, heat shock proteins. large between temperatures stages, much larger 28 DPH, specifically individuals reared 27°C. from line previous phenotypic studies indicated faster growth warmer better performance RAS. Overall, exemplifies controlling during critical early life stages can be essential guarantee success commercial hatchery production techniques.
