Summary: Crime observations are crucial for designing citizens' security strategies, but the dark figure of crime caused by underreporting biases hinders accurate measurements. This study proposes a novel underreporting model based on spatiotemporal events and validates its effectiveness through simulations. The results suggest that this methodology can be used to estimate the underreporting rates of spatiotemporal events, which is essential for public policy design.

Summary: This study provides important data for the release of Aedes aegypti carrying Wolbachia bacteria by analyzing mosquito populations in Jeddah, Saudi Arabia using ovitraps. The findings show that there is no difference in the numbers of eggs laid between basement and non-basement locations, and there is significant spatial structure to populations at some study sites. The data suggest that the quality of breeding environments in Jeddah's arid environment can vary over time, supporting the feasibility of dry season releases.

Summary: We propose a general theoretical model for the spatio-temporal dynamics of animal contests, inspired by interactions between physical particles. The model uses effective interaction potentials to map contest behavior into empirically verifiable rules of contestant motion, allowing simulation of observable dynamics in various realistic scenarios. Assessment strategies and fighting costs can be described as variations in model parameters, and contest duration trends can be derived and understood within the model. The framework enables exploration of spatio-temporal properties of asymmetric contests, such as the emergence of chase dynamics.

Summary: Theoretical studies have shown that environmental heterogeneity and temporal heterogeneity can both impact the evolution of dispersal. In this study, the authors generalize previous models and find richer dynamics, including bistable evolutionary dynamics. They also examine the evolution of conditional dispersal strategy and find that the ability to use patch quality information is important. The study highlights the importance of considering patch quality information in the evolution of dispersal.

Summary: In this paper, a novel deep neural network architecture is proposed that combines graph neural networks and temporal convolutional networks for learning from both the spatial and temporal components of resting-state functional magnetic resonance imaging (rs-fMRI) data. The model is evaluated using samples from the UK Biobank and Human Connectome Project datasets, showing effectiveness and explainability-related features. This approach lays the groundwork for future deep learning architectures focused on the spatio-temporal nature of rs-fMRI data.

Summary: Soil moisture has a fundamental influence on tundra ecosystems, but its local dynamics are often ignored due to lack of data. This study used two mechanistic models to simulate soil moisture and found significant spatial variation, which was underestimated by the models. Soil properties and topography were identified as important drivers of soil moisture dynamics.

Summary: Understanding the spatio-temporal distributions of populations is crucial for the conservation and management of migratory animals. In this study, we used Gaussian process (GP) models and birdwatcher observation data to analyze the differences in distribution between two subspecies of bean goose in Finland during migration. The results showed that the taiga bean goose migrates throughout the country, while the tundra bean goose occurs only in a small area in southeastern Finland and migrates later than the taiga bean goose. By targeting the abundant tundra bean goose through hunting restrictions in southeastern Finland and at the end of the migration period, effective conservation and management can be achieved.

Summary: Forest area in European countries has significantly increased since the 19th century, with at least half of today's forests growing on previously cultivated lands. However, this net forest expansion masks a slow erosion of ancient forests. Meanwhile, forest resource harvesting has shifted towards increased growing stocks in the past two centuries.

Summary: The recruitment of forest trees is influenced by both bottom-up processes and top-down processes. Results from a study in Sweden and France show that canopy opening and ungulate browsing can have significant impacts on the regeneration of oak seedlings, with fencing increasing growth and survival rates but also potentially leading to increased browsing damage in young forest stands.

Summary: The long-term exclusion of deer has a significant impact on forest understorey plant communities, increasing vascular plant richness, diversity, and cover while decreasing bryophyte cover. It reveals the abiotic filtering of plant assemblages that would otherwise be masked by the impact of abundant deer populations, though it does not increase beta diversity due to competitive advantages of remnant species.

Summary: Plant dispersal syndromes are often used to predict dominant dispersal mechanisms, but the classical syndromes may not accurately reflect the actual dispersal events. Endozoochory and epizoochory syndromes may not be helpful in predicting which plants non-frugivores disperse, or by which mechanism, and more empirical research is needed to understand the relationship between plant traits and dispersal mechanisms.

Summary: Understanding animal movement is crucial for studying behavior, distribution, and habitat use. Current models are often complex and lack practicality, but a simple individual movement model based on GPS data has shown promise in capturing spatial complexity and abnormalities in wild animal behavior. Additional features such as interactions and environmental factors can further improve understanding of animal spatial behavior.

Summary: Conventional conservation policies in Europe rely on passive restoration of natural forest dynamics and require complementary conservation efforts in managed forests to achieve biodiversity targets. We studied forest reserves and adjacent managed forests in European France and found that stand structure and browsing pressure have direct and opposite effects on herbaceous plant species diversity, while increasing canopy cover has a negative effect. High stand density has a positive effect on bryophyte diversity, and forest management abandonment mainly affects understory plant communities indirectly through changes in vertical stand structure.

Summary: With the increase in large herbivore populations in northern hemisphere forests, browsing has become a major factor in forest regeneration dynamics. This study examines the impact of browsing on oak saplings and investigates the underlying morphological and chemical traits. The findings show that browsing influences oak sapling attractiveness, but the direction and magnitude of the effect depend on the sapling's growth stage and the number of browsing events.

Summary: Understanding the impact of linear landscape features on animal movements is crucial, especially in fragmented habitats. Large herbivores primarily use linear features as landmarks to demarcate their home range, with different patterns observed in mountain species. In highly fragmented landscapes, the costs of memorizing key features and the need for sufficient area to meet vital needs constrain large herbivores. Linear features play a significant role in how these animals perceive and utilize the landscape, with consistent patterns observed across sexes and species.

Summary: Studying animal movement in the wild is crucial for ecosystem relationships and conservation efforts. Capturing and handling animals for fitting tracking devices can cause behavioral modifications, but wild species have shown resilience to such events, quickly recovering to average behavior. Researchers are encouraged to adapt methods to minimize stress and prioritize animal welfare in research.
