Lifespan theory suggests a shift from a primary orientation towards attaining gains in young adulthood to preventing losses in older adulthood. The current research tested if this motivational shift is reflected in behavioural and emotional responses to risks in non-monetary gains and losses. Study 1 established in a sample of N = 168 younger (18-30 years) and older adults (65-79 years) that a non-monetary gambling task was experienced similarly by the age groups with respect to arousal and valence of the task, and the willingness to continue playing. In Study 2 (N = 83), differences between young (18-30 years) and older (64-85 years) adults' risk-taking in this non-monetary gambling task with mixed gambles were tested while assessing physiological responses (event-related heart rate change) to gain and loss feedback. Behavioural - but not physiological - results confirm hypotheses derived from a lifespan motivational framework regarding age-differential effects of gains and losses.

Forest gains and losses may have unequal effects on forest resilience, particularly given their distinct temporal dynamics. Here, we quantify the sensitivities of boreal forest resilience to forest cover gain and loss using a resilience indicator derived from the temporal autocorrelation (TAC) of the kernel normalized difference vegetation index from 2000 to 2020. Our findings unveil pronounced asymmetric sensitivities, with stronger sensitivity to forest loss (-4.

Understanding the patterns and drivers of species range shifts is essential to disentangle mechanisms driving species' responses to global change. Here, we quantified local extinction and colonization dynamics of giant pandas (Ailuropoda melanoleuca) using occurrence data collected by harnessing the labor of >1000 workers and >60,000 worker days for each of the three periods (TP1: 1985-1988, TP2: 1998-2002, and TP3: 2011-2014), and evaluated how these patterns were associated with (1) protected area, (2) local rarity/abundance, and (3) abiotic factors (i.e.

Changes in winter precipitation accompanying emerging climate trends lead to a major carbon-climate feedback from Arctic tundra. However, the mechanisms driving the direction, magnitude, and form (CO and CH) of C fluxes and derived climate forcing (i.e.

Background: The determinants of differences in host infectivity among Cryptosporidium species and subtypes are poorly understood. Results from recent comparative genomic studies suggest that gains and losses of multicopy subtelomeric genes encoding insulinase-like proteases (INS-19 and INS-20 in Cryptosporidium parvum and their orthologs in closely related species) may potentially contribute to these differences.
Methodology/principal Findings: In this study, we investigated the expression and biological function of the INS-19 and INS-20 of C.

Slope instability represents a substantial secondary hazard post-earthquake, leading to considerable socio-economic losses from the destruction of structures, infrastructure, and human lives. This study addresses the urgent need for precise evaluation of seismic slope stability, a subject that has gained significant attention in earthquake engineering over the past decade. A theoretical framework is proposed that utilizes an improved Sarma method, estimating seismic forces and safety factors based on limit equilibrium theory.
