Resilience to environmental fluctuations is important for all animals. It common that animals encounter multiple stressful events at the same time, cumulative impacts of which are largely unknown. This study examines effects temperature and pH on nervous system crabs live in fluctuating environments Northern Atlantic Ocean. The ranges tolerance one perturbation, temperature, reduced under influence a second, pH.

Resilience of circuits to environmental challenge

Current Opinion in Neurobiology, Journal Year: 2024, Volume and Issue: 87, P. 102885 - 102885

Animals of all kinds evolved to deal with anticipated and unanticipated changes in a variety features their environments. Consequently, environmental perturbations, adaptations, acclimation involve myriad factors that, together, contribute resilience. New work highlights the importance neuromodulation control resilience, illustrates that different components nervous system may be differentially resilient perturbations. Climate change is today pushing animals previously challenges, therefore understanding complex biology adaptation various conditions takes on new urgency.

Impact of developmental temperature on neural growth, connectivity, and function

Science Advances, Journal Year: 2025, Volume and Issue: 11(3)

Environmental temperature dictates the developmental pace of poikilothermic animals. In Drosophila , slower development at lower temperatures results in higher brain connectivity, but generality such scaling across and regions its impact on function are unclear. Here, we show that connectivity scales continuously temperatures, agreement with a first-principle model postulates different metabolic constraints for growth organism. The predicts wiring under cycles nonuniform temporal neural temperatures. Developmental has notable effects odor-driven behavior. Dissecting circuit architecture neurons olfactory pathway, demonstrate does not alter odor encoding first- second-order neurons, it shifts specificity connections onto third-order mediate innate behaviors. We conclude while some computations robust to wiring, others exhibit phenotypic plasticity possible adaptive advantages.
