Summary: This article discusses the potential benefits of integrating landscape graphs and genetic graphs in landscape genetics. By comparing different features and partitions of these graphs, the influence of intra-patch features and inter-patch connectivity on genetic structure can be examined, as well as the sensitivity of genetic diversity and differentiation to landscape factors. Additionally, the integration of these graphs through gravity models can enhance their joint use for various theoretical and applied objectives.

Summary: Understanding the genetic diversity and structure of the Southern Flying Squirrel in the heavily urbanized northeastern United States is important for assessing the impact of landscape fragmentation and forest loss on common species. Through a landscape genetics approach, we found that gene flow occurs between populations despite landscape changes, but individuals at the eastern periphery may have been temporarily isolated in the past. The regeneration of hardwood forests presents a positive outlook for the species' genetic integrity and connectivity in the region.

Summary: In this study, the reliability of cost value inference in connectivity models was assessed under different migration rates, population spatial patterns, and degrees of population size heterogeneity. The study also examined whether considering intra-population variables improved the inference when drift was spatially heterogeneous. The results showed that considering intra-population variables can improve the reliability of cost value inference and better identify the true cost scenarios in certain situations.

Summary: The study in Germany found that road density, agricultural lands, and settlements are important landscape variables influencing genetic connectivity in European wildcats. Among these, road density, particularly state roads, had the strongest impact, highlighting the need to consider different road types in conservation planning.

Summary: Species dependent on fragmented habitats in South Africa are facing declines in population size and disruption of gene flow due to landscape transformation. The study found that landscape features play a crucial role in maintaining gene flow for forest-dependent birds, with some species more impacted than others by anthropogenic landscape changes.

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: This study utilizes circuit theory and least-cost path methods to present an objectified and applicable green network for spatial planning. Analysis of the Least-cost Path revealed 69 least-cost paths passing through small green areas and streams in the city. Circuit theory was used to distinguish areas and assess the effectiveness of the green network.

Summary: The study focuses on the importance of landscape features and their scale effects on gene flow, using genetic algorithms to optimize landscape resistance surfaces. Results suggest that multisurface multiscale LRS outperformed other approaches, especially large-scale LRS had the greatest impact on eastern indigo snake connectivity.

Summary: The expansion of the global road network poses a conflict between human well-being and the biosphere, which could be addressed by improving the Environmental Impact Assessment (EIA) process. We propose a method to incorporate landscape-level wildlife connectivity in EIAs using satellite imagery and basic species data. This method identifies key locations for wildlife connectivity and specifies mitigation measures. Testing the method with field data on four species showed conservative identification of key locations. We also highlight how existing traffic bridges and culverts can be included in the mitigation strategy.

Summary: Decreased genetic diversity, gene flow rates, and population connectivity in Asiatic cheetahs have led to increased inbreeding rates and extinction risks. This study used genetic markers to estimate genetic diversity and relatedness, minimum effective population size, and gene flow between subpopulations, as well as to assess population structure. The results indicate low genetic diversity and high relatedness in both Northern and Southern Subpopulations. Inferred corridors potentially connecting subpopulations show signs of gene flow and movement of individuals, but recent generations show no traces of gene flow. The extremely low estimated effective population size and decreased genetic diversity highlight the urgent need for population reinforcement, conservation of prey populations, and removal of obstacles to connectivity to prevent the impending extinction of this iconic species.

Summary: Ecological heterogeneity promotes species persistence and diversity. This study found that seasonal heterogeneity positively influences the survival of American martens and outperforms traditional forest metrics. However, there is temporal discordance caused by seasonal changes in heterogeneity. Management strategies that increase seasonal aspects of heterogeneity may aid the recovery of sensitive species in the face of environmental change.

Summary: In order to understand how pharmacological interventions affect brain function, this study investigates the relationship between the distribution of neurotransmitter receptors and transporters in the brain and the changes in functional connectivity induced by psychoactive drugs. The results show that there is a correlation between the effects of drugs on brain function and multiple neurotransmitter systems. Additionally, the effects of anesthetics and psychedelics are organized along hierarchical gradients of brain structure and function. The study also highlights the similarity between regional susceptibility to drug interventions and disorder-induced structural alterations.

Summary: Landscape genetics is an interdisciplinary field that studies the impact of environmental features and evolutionary processes on genetic variation, with implications for ecology, evolution, and conservation biology. Despite being well suited for primatologists, this method is currently underutilized and further research and applications are needed.

Summary: Vegetation plays a crucial role in conserving biodiversity in urban areas, but the lack of fine spatial resolution vegetation inventories and ecological information poses a challenge for conservation efforts. The use of very high-resolution imagery can help map different types of vegetation covers in cities, assess their structural and functional connectivity, and evaluate their health status.

Summary: The study describes the isolation of two strains of PUUMALA orthohantavirus from two distinct French geographical areas: Ardennes (endemic area) and Loiret (non-endemic area). By selecting wild bank voles, cultivating the strains efficiently in Vero E6 cells, and propagating them in immunologically neutral bank voles, the impact of isolation methods on viral diversity was better assessed through high-throughput and Sanger sequencing results.
