Resilience describes successful adaptation in the face of adversity, commonly inferred from trajectories of well-being following major life events. Alternatively, resilience was conceptualised as a psychological trait, facilitating adaptation through stable individual characteristics. Both perspectives may relate to individual differences in how stress is regulated in daily life. In the present study, we combined these perspectives on resilience. Our sample consisted of N = 132 middle-aged adults, who experienced major life events in between two waves of a longitudinal study. We implemented latent change regression models to predict change in affective distress. As predictors, we investigated trait resilience and correlates of resilience in daily life (stressor occurrence, stress reactivity, positive reappraisal, mindful attention, and acceptance), measured using experience sampling (T = 70 occasions). Unexpectedly, trait resilience was not associated with change in distress. In contrast, resilience correlates in daily life, most notably lower stress reactivity, were associated with more favourable change. Higher trait resilience related to higher average mindfulness, higher reappraisal, and lower negative affect. Overall, while trait resilience translated into everyday correlates of resilience, it was not predictive of changes in affective distress. Instead, precursors of changes in well-being may be found in correlates of resilience in daily life.

Background: Although cognitive decline is a trait related to aging, some individuals are resilient to the aging process, defined as SuperAgers. Studying the neural underpinnings of SuperAgers may improve the understanding of AD pathology. In this study, our aim was to analyze amyloid and neurodegeneration imaging biomarkers in SuperAgers.

Enhancing salt tolerance genetically through defining the genetic and physiological mechanisms intergenerational and transgenerational stress memory that contributes to sustainable agriculture by reducing the reliance on external inputs such as irrigation and improving the adaptability of barley to changing climate conditions. Salinity stress poses a substantial challenge to barley production worldwide, adversely affecting crop yield, quality, and agricultural sustainability. To address this, the present study utilized a genome-wide association san (GWAS) to identify genetic associations underlying intergenerational and transgenerational stress memory in response to salinity in a diverse panel of 138 barley accessions.

It is currently uncertain how selection of more efficient animals might impact other traits such as resilience (which, in this context, is defined as the ability of an animal to sustain or revert quickly to its previous production level and health status after a disturbance), especially in small ruminants. However, improving, or at least maintaining, resilience is of utmost importance to ensure livestock production in the face of external perturbances, which are expected to become more prevalent in the near future due to climate change and global instability. This study was conducted to investigate whether a nutritional challenge consisting of animals receiving only 70% of their voluntary feed intake (DMI) for 26 d, might differentially affect the response of high- and low-feed efficiency (FE) sheep.

Understanding plant adaptations in extreme environments is crucial, as these adaptations often confer advantages for survival. However, a significant gap exists regarding the genetic mechanisms underlying these adaptations and their responses to human-induced rapid environmental change (HIREC). This study addresses the question of whether genetic convergence occurs among plants with similar adaptive features, specifically focusing on isobilateral leaves in mangrove species.

L., (pitaya) is an important tropical fruit crop, and faces significant challenges from soil salinity and heavy metal toxicity. This study explores the role of melatonin (M) in enhancing stress tolerance in pitaya against salinity (S) and copper (Cu) toxicity, both individually and in combination (SCu).
