Summary: This study examines the demographic history of the monarch butterfly and its host plant, the common milkweed. The research shows that both species have experienced population expansion and no evidence of population decline. The decline in monarch butterfly abundance observed in recent years may be due to a mismatch between the overwintering census population and the effective population size.

Summary: Heart attack is a leading cause of death globally, and heart-related diseases have resulted in increased healthcare expenditure. This study proposes a method for diagnosing arrhythmia based on electrocardiogram signals, utilizing long-term recording devices to capture rare abnormal events. By optimizing feature vectors and applying convolutional neural networks for signal classification, the proposed method achieves comparably high classification accuracy.

Summary: Swarm intelligence involves the Monarch butterfly optimization (MBO) algorithm inspired by the migration behavior of monarch butterflies. Through migration and adjusting operations, individuals in MBO are updated to solve global optimization problems. This paper reviews the MBO algorithm, its modifications, applications, and suggests future research directions.

Summary: Since the 1960s, scientists have observed the winter breeding behavior of North American monarch butterflies, particularly in areas with non-native milkweed plants. Warmer climates and the presence of milkweed plants and suitable temperatures for immature monarch development are key factors contributing to this behavior. The implications of winter breeding differ in the eastern and western regions due to differences in migration ecology, milkweed species, and climate changes.

Summary: Animals use an internal compass for navigation, which is crucial for long-distance migrating animals like monarch butterflies. During flight, the heading-direction neurons in monarch butterflies change their tuning, transforming the central-complex network to function as a global compass. This allows for robust heading representation even under unreliable visual scenarios.

Summary: Monarch butterflies exhibit enhancements to long-term memory that enable them to optimize foraging efficiency during their annual fall migration, increasing the chance of overwinter survival. The possibility of seasonal changes in visual long-term memory among female monarchs warrants further investigation.

Summary: In this paper, a comprehensive agent-based model is developed for community resilience planning. The model incorporates agents representing businesses, healthcare systems, and people, along with agents for education systems, utilities, and households, to simulate the Centerville testbed subjected to tornado hazards. The model introduces resilience measures and evaluates various strategies for pre-disaster preparedness. The results demonstrate the capability of the model to capture the complex behaviors and dynamics of interdependent systems within a community, as well as assess the impact of disruptions and mitigation strategies for community planning.

Summary: The research found that concentrating milkweed growth in the central region is more effective in increasing the size of overwintering colonies compared to equivalent growth in the southern region, with growth in the northern region having minimal impact. While increasing milkweed stems in the south does not play a key role in increasing colony size, it is crucial for maintaining the population above a critically small size.

Summary: The study investigates the behavior of agent-based models on long time scales through the use of a transfer operator approach, bridging the gap between pathwise results for large populations and approaches for studying dynamical behavior on long time scales. This method provides a rigorous analysis of rare events, including their associated asymptotic rates on timescales exponentially scaling with population size.

Summary: Establishing habitat for monarch butterflies in agricultural landscapes of the north central United States is crucial for population conservation, but potential impacts of insecticide use must be considered. Research findings indicate that the benefits of establishing habitat close to crop fields outweigh the adverse effects of insecticide spray drift.
