Degrees of freedom: temperature’s influence on developmental rate

Current Opinion in Genetics & Development, Journal Year: 2024, Volume and Issue: 85, P. 102155 - 102155

Published: Feb. 9, 2024

Temperature exerts a fundamental influence across scales of biology, from the biophysical nature molecules, to sensitivity cells, and coordinated progression development in embryos. Species-specific developmental rates temperature-induced acceleration indicate that these sensing mechanisms are harnessed dynamics. Tracing how temperature propagates through biological pace can therefore reveal embryogenesis remains robust environmental influences. Cellular protein homeostasis (proteostasis), cellular metabolic rate linked both species-specific tempos specific cell types, hinting toward generalized timing control. New methods extract information single-cell profiling experiments driving further progress understanding direct cell-autonomous responses, coordination evolutionary modifications timing.

Threshold shifts and developmental temperature impact trade-offs between tolerance and plasticity

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2016)

Published: Feb. 7, 2024

Mounting evidence suggests that ectotherms are already living close to their upper physiological thermal limits. Phenotypic plasticity has been proposed reduce the impact of climate change in short-term providing time for adaptation, but tolerance-plasticity trade-off hypothesis predicts organisms with higher tolerance have lower plasticity. Empirical is mixed, which may be driven by methodological issues such as statistical artefacts, nonlinear reaction norms, threshold shifts or selection. Here, we examine whether (organisms require stronger treatments induce maximum plastic responses) influence trade-offs hardening capacity desiccation and critical (CT

Genetics and ontogeny are key factors influencing thermal resilience in a culturally and economically important bivalve

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 19, 2024

Increasing seawater temperatures coupled with more intense and frequent heatwaves pose an increasing threat to marine species. In this study, the New Zealand green-lipped mussel, Perna canaliculus, was used investigate effect of genetics ontogeny on thermal resilience. The culturally economically significant mussel P. canaliculus (Gmelin, 1971) has been selectively-bred in for two decades, making it a unique biological resource genetic interactions temperate bivalve Six full sibling families four different ages, from early juveniles (6, 8, 10 weeks post-fertilisation) sub-adults (52 post-fertilisation), were experimentation. At each age, family exposed three-hour heat challenge, followed by recovery, survival assessments. shell lengths live dead juvenile mussels also measured. Gill tissue samples collected after challenge quantify 70 kDa shock protein gene (hsp70). Results showed that genetics, size influence resilience LT

Vulnerability of amphibians to global warming

Published: Jan. 11, 2024

Amphibians are the most threatened vertebrates, yet their resilience to rising temperatures remains poorly understood. This is primarily because knowledge of thermal tolerance taxonomically and geographically biased, compromising global climate vulnerability assessments. Here, we employed a novel data imputation approach predict heat 60% amphibian species assessed daily temperature variation in refugia. We found 198 out 5203 currently exposed overheating events shaded terrestrial conditions. Despite accounting for plasticity, 4°C increase would create step-change impact severity, pushing 9.4% beyond physiological limits. In Southern Hemisphere, tropical encounter disproportionally more events, while Northern non-tropical susceptible. Our findings challenge evidence latitudinal gradients risk underscore importance considering climatic variability Notably, our conservative estimates assume access microenvironments, implying that warming’s impacts on amphibians may exceed projections. microclimate-explicit analyses also demonstrate how availability vegetation water bodies critical buffering during waves. Immediate action needed preserve manage these microhabitat features.

Dissipative scaling of development and aging in multicellular organisms

Biosystems, Journal Year: 2024, Volume and Issue: 237, P. 105157 - 105157

Published: Feb. 15, 2024

Evolution, self-replication and ontogenesis are highly dynamic, irreversible self-organizing processes dissipating energy. While progress has been made to decipher the role of thermodynamics in cellular fission, it is not yet clear how entropic balances shape organism growth aging. This paper derives a general dissipation theory for life history organisms. It implies self-regulated energy facilitating exponential within hierarchical entropy lowering self-organization. The predicts ceilings expenditures imposed by geometric constrains, which promote thermal optimality during development, dissipative scaling across organisms consistent with ecological laws combining isometric allometric terms. also illustrates growing can tolerate damage through continuous extension production new structures low entropy. However, when reduce their rate cell division reach steady adult state, they become thermodynamically unstable, increase internal accumulating damage, age.

Developmental plasticity of the cardiovascular system in oviparous vertebrates: effects of chronic hypoxia and interactive stressors in the context of climate change

Journal of Experimental Biology, Journal Year: 2024, Volume and Issue: 227(20)

Published: Aug. 7, 2024

Animals at early life stages are generally more sensitive to environmental stress than adults. This is especially true of oviparous vertebrates that develop in variable environments with little or no parental care. These organisms regularly experience fluctuations as part their natural development, but climate change increasing the frequency and intensity these events. The developmental plasticity will therefore play a critical role determining future fitness survival. In this Review, we discuss compare phenotypic consequences chronic hypoxia on cardiovascular system vertebrates. particular, focus species-specific responses, windows, thresholds for responses interactive effects other stressors, such temperature hypercapnia. Although important progress has been made, our Review identifies knowledge gaps need be addressed if fully understand impact vertebrate system.

An individual's fitness cost associated with environmental change likely depends on the rate of adaptive phenotypic plasticity, and yet our understanding plasticity rates in an ecological evolutionary context remains limited. We provide first quantitative synthesis existing data, focusing acclimation temperature tolerance ectothermic animals, where we demonstrate applicability a recently proposed analytical approach. The analyses reveal considerable variation this trait among species, half-times (how long it takes for initial deviation from acclimated phenotype to be reduced by 50% when individuals are shifted new environment) ranging 3.7 770.2 h. Furthermore, differ higher taxa, being amphibians reptiles than crustaceans fishes, insects intermediate. argue that more comprehensive will attained through increased focus parameter.

orchaRd 2.0: An R package for visualizing meta-analyses with orchard plots

Published: Jan. 8, 2023

1. Although meta-analysis has become an essential tool in ecology and evolution, reporting of meta-analytic results can still be much improved. To aid this, we have introduced the orchard plot, which presents not only overall estimates their confidence intervals but also shows corresponding heterogeneity (as prediction intervals) individual effect sizes. 2. Here, added significant enhancements by integrating many new functionalities as orchaRd 2.0. This updated version allows visualisation heteroscedasticity (different variances across levels a categorical moderator), marginal (e.g., marginalising out effects other than one visualized), conditional (i.e., different groups conditioned upon specific values continuous variable), visualizations all types interactions between two categorical/continuous moderators.3. 2.0 additional functions calculate key statistics from multilevel models such I2 R2. Importantly, contributes to better complying with PRISMA-EcoEvo (preferred items for systematic reviews meta-analyses evolution). Taken together, improve presentation facilitate exploration previously neglected patterns. 4. In addition, part literature survey, found that graphical packages are rarely cited (~3%). We plea researchers credit developers maintainers packages, e.g., citations figure legend, acknowledging use relevant packages.
