Summary: This study examines how the COVID-19 pandemic has affected sleep health globally. The findings suggest that lockdown policies have led to changes in sleep timing and duration, with a modest increase in time in bed (TIB) and a delay in sleep timing. These changes were more pronounced in the earlier months of the pandemic and may diminish as restrictions are lifted.

Summary: By analyzing sleep data from two human studies with extended sleep opportunities, it was found that total sleep duration, REM sleep duration, and non-REM sleep duration decreased, while sleep latency increased across nights. It takes multiple nights to reach steady-state values, indicating a multi-day homeostatic sleep process responding to self-selected insufficient sleep duration prior to the study. Once steady-state values were reached, there were large night-to-night variations in total sleep time and other sleep metrics.

Summary: This study aimed to establish the optimal cutoffs of sleep timing and duration to assess various cardiovascular disease risk factors. The findings showed that bedtime between 9:00 PM to 0:30 AM for men and 10:00 PM to 11:00 PM for women is appropriate. The cutoff range was slightly earlier for participants aged 65 years and older. Early MSFsc between 12:00 AM to 3:00 AM and sleep durations around 6 hours were associated with the optimal cutoffs for assessing CVD risk factors.

Summary: The objective of this study was to evaluate the association between short sleep duration or later sleep timing and insulin resistance (IR) in late adolescence. The findings suggest that insufficient sleep duration and late sleep timing are risk factors for the development of IR in late adolescence over a 2-year period.

Summary: Sleep deprivation and sleep restriction are common in adolescents, and the duration and timing of screen use are associated with these problems. More than 2 hours of evening use and all-night use increase the risk of insomnia, non-refreshing sleep, and impaired daytime functioning.

Summary: The study found nonlinear associations between sleep duration, midpoint sleep time, and depressive symptoms in the older adult population. Sleep duration shorter than 4 hours was associated with higher levels of depressive symptoms, while midpoint sleep time after 01:00 was positively correlated with depressive symptom scores.

Summary: Given the complex relationship between sleep and neurodegenerative processes, this study aimed to examine the association between sleep parameters and dementia incidence, and characterize the trajectories of sleep patterns before dementia diagnosis. The findings revealed that long sleep duration and earlier bedtime may impact dementia incidence. Trajectories of sleep durations and time in bed showed faster increases in dementia cases compared with controls up to 12 years before dementia onset.

Summary: This study investigated the correlation between bullying victimization (BV) characteristics and sleep quality among Chinese medical students. The results showed that the timing, duration, and patterns of BV were positively associated with poor sleep quality. Chronic exposure to BV had a cumulative effect on sleep quality, with a dose-response relationship.

Summary: This study showed that public sector employees close to retirement age with high job strain tended to have longer sleep duration on free days and were more likely to extend their sleep from workdays to free days, mainly due to a greater delay in awakening times.

Summary: Research suggests that consuming energy earlier in the day may have cardiometabolic benefits. This study found associations between fasting duration, timing of meals, and cardiometabolic endpoints. Starting energy consumption earlier in the day was linked to improvements in cardiometabolic markers.

Summary: Social-distancing measures due to COVID-19 have varied effects on sleep patterns in young adults, with remote learning leading to later bedtimes but not increased overall sleep duration. Individual differences in chronotype may influence how students perceive the impact of these measures on their sleep.

Summary: The research and conservation community has successfully utilized citizen science (CS) data to gather ecological knowledge, but there is a lack of examples directly informing policy; current applications mainly come from limited scope programs, while the potential of unrestricted CS data for policy-making remains largely untapped; there is a call to move beyond questioning the reliability of CS data and to utilize unrestricted CS programs for generating the evidence base needed to inform policy decisions.

Summary: Research has shown that the magnitude of nocturnal bird migration, building light output, and wind conditions are the most important predictors of fatal collisions. Reducing building light output, controlling weather conditions, and decreasing light pollution can reduce bird mortality rates.

Summary: Little is known about how animals overcome temporal constraints on movement during dispersal. This study used GPS tracking of vulturine guineafowl and found that dispersers showed the greatest increase in movement at the same times of day when they moved the most prior to dispersal. These findings suggest that individuals face the same ecological constraints during dispersal as they do in daily life and achieve large displacements by maximizing movement when conditions are most favorable.

Summary: Winner and loser effects are observed in many animals, and recent experiments suggest that they may also occur in humans. In two experiments involving video games and reading comprehension, participants who won in the first phase performed significantly better in the second phase compared to those who lost. The effect size was larger in the video game experiment, and men and women showed similar magnitudes of winner and loser effects.

Summary: This study examines the trade-off between mating effort and thermoregulatory behavior in dragonflies in response to temperature changes, and investigates the effect of wing melanin on these behaviors. The results indicate that as temperature increases, dragonflies reduce their mating effort and increase their thermoregulatory behavior.

Summary: In this study, it was found that African penguins could use ventral dot patterns to recognize their lifelong partner and nonpartner colonymates. This challenges the previous assumption of limited visual involvement in penguin communication, highlighting the complex and flexible recognition process in birds.

Summary: Environmental conditions, particularly temperature, have a significant impact on animal behavior. This study focused on aggression in Neolamprologus pulcher fish and found that aggression rates increased with temperature at lower levels, but decreased after reaching a peak. Additionally, the influence of high temperatures on aggression changed over time during the trials. These findings provide a more comprehensive understanding of the short-term effects of temperature on aggression and highlight the importance of considering non-linear changes in thermal performance.

Summary: Human activities have affected the availability of resources for wildlife, particularly through the provision of anthropogenic food subsidies at landfill sites. This study explores the influence of age on landfill attendance and foraging behavior in white storks. Adult storks visit landfills more frequently and show dominance over juveniles in food acquisition. Juveniles have limited access to landfill resources and are forced to use lower quality areas.
