Summary: This paper introduces a statistically and computationally efficient method for population-level analysis of home-range areas, based on autocorrelated kernel density estimation (AKDE). The method can account for variable temporal autocorrelation and estimation uncertainty. By applying the method to empirical examples, the study quantifies differences between species, environments, and sexes. The approach allows researchers to accurately compare different populations while maintaining statistical precision and power.

Summary: This study investigates the impact of human population movement on malaria risk in rural Peruvian Amazon using self-reported travel surveys, GPS trackers, and a Bayesian spatial model. The findings suggest that human population movement plays a significant role in sustaining malaria transmission in the region.

Summary: Genetic diversity has differing effects on population size and spread rate in benign and challenging habitats, with no impact on population size in benign habitats but an increase in challenging habitats. However, genetic diversity does increase population spread rates in benign habitats. Populations with low genetic diversity show higher variance in spread, particularly in challenging habitats. This challenges the common view that genetic bottleneck limits invasion success in challenging environments.

Summary: This study investigated the development of migratory and dive behavior in juvenile harp seals during their first year. The results showed similarities in migratory movements and differences in diving behavior between different breeding populations of harp seals. The study also highlighted the influence of intrinsic and extrinsic factors on shaping early life behavior.

Summary: This study reveals that roads act as substantial barriers to bee movement, reducing the pollen flow between plants located across roadways from one another. Road characteristics, particularly width and traffic volume, as well as bee size, mediate this effect significantly. The findings suggest that the impact of roads on pollinators and pollination can potentially be mitigated through design strategies aimed at reducing human traffic accidents.

Summary: Variation in river flow is crucial for the movement of freshwater fish species, with environmental flows playing a significant role in influencing their behavior. In a study of two native fish species in regulated rivers in Australia, it was found that environmental flow releases impacted the movement behaviors of the fish. Different species responded differently to environmental flow releases, and the timing of flow pulses was shown to influence their movements.

Summary: The Lake Sturgeon has experienced a significant decline in abundance over the past 150 years. Stocking has been used since the 1990s to recover different populations of Lake Sturgeon in North America. A genotype-by-sequencing study was conducted to guide stocking strategy in Manitoba's Nelson River, revealing spatial structuring among different populations and recommending separate stocking for different sections of the river.

Summary: Movement plays a crucial role in animal distribution and ecosystem structure. Habitat loss and fragmentation can hinder movement and lead to population declines. This study examines the movement behavior of Murray cod in a highly modified floodplain ecosystem, finding that movement is influenced by environmental conditions and river flow regulations. Flow management can help restore keystone species habitats and ensure their critical life functions.

Summary: Spatial genetic variation in bobcats (Lynx rufus) is influenced by habitat preferences, with landscape variables impacting gene flow at different spatial scales. Male-biased dispersal and habitat type play key roles in shaping genetic structure in bobcat populations. The study highlights the importance of multiscale approaches in understanding spatial genetic patterns in highly mobile species like bobcats.

Summary: Research using fruit flies as a model species shows that insect dispersal behavior can be influenced by wind under specific conditions. Through release-and-recapture experiments, it was observed that even tiny fruit flies could disperse tens of kilometers in light winds. An agent-based model explains the specific behaviors of fruit flies during dispersal, depicting a balance between covering large distances while intercepting odor plumes from upwind sources.

Summary: Understanding the movement of species is crucial for effective management and conservation of their populations. This study used GPS tracking data to investigate the migration patterns of Sandhill Cranes and developed a model integrating this information with aerial survey data to assess the impact of survey timing on population monitoring and harvest management strategies. The results showed that the current survey timing had limited impact on the estimation of crane distribution, but significantly influenced the harvest allocation in mid to late October.

Summary: This study examines the impact of population mobility on the spatial transmission of COVID-19 using Baidu's population migration data and the spatial Durbin model. The results show that population flows play a significant role in epidemic spreading, and the spatial spillover effect also affects the transmission of the epidemic.

Summary: Genetic exchanges between closely related groups of organisms with different adaptations have both beneficial and detrimental consequences. This study focuses on the origin and spread of two geographically overlapping ecotypes of the African grass Alloteropsis angusta using phylogenomics and population genomics. The findings suggest that occasional pollen movements can result in the transfer of nuclear genomes between different ecotypes, while the chloroplast genomes remain consistent. This indicates that hybridization can facilitate the geographical dispersal of distinct ecotypes of the same grass species.

Summary: This study investigated whether wandering albatrosses respond to microbarom infrasound at sea. The results showed that albatrosses not only respond to winds encountered in situ but also move toward source regions associated with higher sound pressure levels. This suggests that albatrosses may be responding to long-range infrasonic cues, which are important for optimizing their flight over long distances.
