Summary: Context-dependent dispersal has significant impacts on the dynamics and genetics of populations, as observed in the great crested newt SSP studied. Individuals in the SSP showed preference for high-quality ponds, leading to weak but significant spatial genetic structure. At a regional level, the presence of independent demographic units and low effective dispersal rates indicate limited long-distance dispersal and demographic isolation in anthropogenic landscapes.

Summary: Global changes can lead to species declines and extinctions through habitat destruction and degradation, with distinct consequences for species dynamics and extinction. Habitat degradation has a faster impact on species populations, particularly for rare species, while habitat destruction shows clear thresholds. Predicting the long-term impacts of global changes on species can be based on species traits and the location and steepness of thresholds.

Summary: Dispersal behavior has important effects on spatial population dynamics and persistence, and we should include such non-random dispersal in metapopulation models.

Summary: This study examined the spatial dynamics of a population of tiger moths and its pathogen, and found that habitat type and weather influenced the dynamics. High-quality habitat patches had faster population growth rates, weaker delayed density dependence, and lower amplitudes of long-period oscillations. The infection rate was higher in high-quality habitat, likely due to higher population densities and no differences in pathogen persistence.

Summary: The study highlights the impact of sex and land use on the spatial ecology and habitat selection of adult wild boar in the Mediterranean region. Male wild boar exhibited higher activity levels and larger daily range in mixed farms compared to fenced hunting estates, with lower values observed in protected areas.

Summary: Habitat loss is a significant threat to biodiversity, and here, the effects of habitat fragmentation on species occurrence are investigated. Two field experiments were conducted, manipulating habitat loss, fragmentation, and patch size, and it was found that fragmentation has a significant impact on species occurrence, while patch size influences the frequency of species occurrence.

Summary: It is found that genetic diversity, spatial genetic structure, and gene flow of forest plant populations are influenced by the permeability of agricultural matrix in fragmented landscapes. Forest specialist plants are more vulnerable to fragmentation and require higher habitat quality for population maintenance. Therefore, it is important to conserve ancient forest fragments and restore functional connectivity among forest patches within agricultural landscapes.

Summary: In rural landscapes, the composition and management intensity of agricultural areas affect genetic diversity, spatial genetic structure, and gene flow in forest plant populations. This study found that low matrix permeability disrupts gene flow and decreases spatial genetic structure, particularly for forest specialist species.

Summary: The quality of corridors positively impacts the probability of dispersal, net movement, and rate of change in population size. Corridor length and width affect the rate at which populations increase and the number of individuals dispersing.

Summary: This study focused on the population structure and reproductive biology of the lesser spider crab, Maja crispata, in the Sea of Marmara, Turkey. The research found a predominance of males, with the largest individual recorded for the species. Ovigerous females were observed between March to November, accounting for 8.37% of the females in the study.

Summary: This paper analyzes the spatial distribution of the Swiss population using fractal concepts and unsupervised learning algorithms. By calculating local growth curves to develop a high-dimensional feature space, and using clustering algorithms to reveal spatial population distribution patterns, the approach provides comprehensive local information on the density and homogeneity/fractality of spatially distributed point patterns.

Summary: Habitat loss and fragmentation are major drivers of global biodiversity loss, affecting species differently based on their extinction risks and dispersal ranges. Various network types and habitat loss scenarios influence the robustness of metapopulations differently. Graph-theoretic metrics such as average clique size, redundancy, and clustering coefficient are reliable indicators of metapopulation robustness in the face of habitat loss, especially for sensitive species.

Summary: Spatial genetic patterns of snow leopard population in the Qilian mountains of China were characterized using spatially explicit indices of diversity and Principal Component Analysis. The genetic patterns showed significant spatial structure, with broad geographical division and fine-scale cline of differentiation. The study highlights the importance of considering spatial factors in understanding genetic diversity and isolation effects in wildlife populations.

Summary: This paper investigates the relationship between synchrony and oscillation types in a two-patch system and finds that dispersal has a significant impact on population dynamics. With low levels of dispersal, increasing synchrony drives oscillating populations towards equilibrium; with medium to high levels of dispersal, oscillations may arise from equilibrium with low levels of synchrony.

Summary: This study focuses on the sensitivity analysis of two length-based methods, namely length-based indicators (LBI) and length-based spawning potential ratio (LBSPR), in the Bay of Biscay and the Iberian Coast ecoregion. The results indicate that both methods are sensitive to variations in input parameters, with the accuracy of the L-infinity parameter having a more significant impact on the assessment results.
