Summary: AFLP analysis revealed genetic polymorphism among wabisuke camellia and its relative species, suggesting the two old 'Uraku' trees are asexually-propagated clonal strains. The genetic distance between wabisuke cultivars and Chinese camellias was greater than that between wabisuke cultivars and Camellia japonica. Wabisuke camellias can be classified into two subgroups based on their genetic characteristics.

Summary: This study evaluated the genetic structure of 85 sideoats grama populations in Mexico and modeled the environmental niche of genetic clusters of this species over time. The genetic analysis revealed two genetically different clusters with different environmental niches at present time, which necessitate the use of local germplasm from each environmental niche for selection and restoration programs. Furthermore, the study highlighted the importance of considering climate change for genotypes selection and restoration programs as the environmental niche of genetic clusters will change in the future.

Summary: This study reveals that genetic diversity in honeycomb worm populations is highest at the edges of its species range and lowest at the center. Glacial cycles likely led to extirpation of central populations, while populations in the north may have persisted in glacial refugia. Overall, populations within biogeographic regions are well-connected, but there is strong genetic differentiation between regions.

Summary: This study utilized a long-term time series to investigate the winter habitat use of Arctic lemmings. The results showed that lemmings preferred areas with a high proportion of Dryas heath and demonstrated some flexibility in resource use. Additionally, lemmings showed a preference for sloped terrain, which enhances the formation of deep snow drifts and provides better protection.

Summary: Many plants develop fruits to attract animals for seed dispersion, but some plants with endozoochoric seed dispersion do not have attractive fruits. The Foliage is the Fruit (FF) hypothesis proposes that the entire biomass of plants exists to encourage herbivores to consume them, enhancing seed intake and dispersion. A study tested the FF hypothesis by combining greenhouse seedling emergence and DNA metabarcoding analysis of moose feces, and found that the species composition revealed by the methods did not largely overlap, suggesting a disagreement with the FF hypothesis.

Summary: Comprehensive biodiversity data is crucial for understanding the impact of global change on organisms at different trophic levels and evaluating interspecific interactions. Molecular approaches like DNA metabarcoding are enhancing our ability to inventory biodiversity. However, comprehensive reconstructions of communities are still rare. Most metabarcoding studies in recent years have used few markers and analyzed limited taxonomic groups. This review provides an overview of emerging approaches that can enable all-taxa biological inventories and suggests new development directions for improving broad-scale biodiversity analyses in the future.

Summary: Large gulls, including the little-studied Siberian migrant Vega gull, show consistent migratory patterns and behavior, with preference for coastal routes and long-distance flights between breeding and wintering grounds. Spring migration is faster and more synchronized than autumn migration, with higher flight altitudes and more day and twilight flights. Individuals exhibit strong site fidelity to their breeding and wintering sites, but show higher between-individual variation in autumn. Timing of spring migration is likely influenced by snowmelt, while the duration of migration windows could be related to flyway habitats. Ongoing environmental changes may impact migration timing and duration.

Summary: In the face of rapid environmental changes, animal behavioural plasticity becomes an important adaptive potential. This study evaluates the contribution of non-invasive environmental DNA (eDNA) methods in assessing intraspecies behavioural plasticity in foraging behaviour. The results suggest that there are intergroup variations in diet composition among wild vervet monkey groups, which may be influenced by social dynamics and group size. The study emphasizes the potential of using eDNA to study social groups and highlights the importance of considering social and demographic factors in understanding intraspecific behavioural plasticity.

Summary: Assessing biodiversity loss and species extinction is essential for raising awareness of the impacts of ongoing climate change. Prioritizing protected areas is a practical and applicable management measure to conserve endangered species. A novel conservation index (CI) was developed to prioritize areas and populations of an endangered mountain tree species based on mountain topography, genetic diversity, and hypothetical climate change. The CI was applied to an endemic and threatened species in Morocco, providing a scale for conservation priority.
