Summary: This study aimed to investigate the genetic relationship between 12 dromedary populations from different geographical locations and ecology in the Arabian Peninsula. The results showed a high level of genetic admixture and gene flow among the populations, with genetic relationships not fully corresponding to ecological classification.

Summary: Knowledge of the geographic genetic structure of exploited and endangered species is crucial for sustainable management. In this study, the genetic structure of lake sturgeon across their Canadian range was analyzed using microsatellite loci. The results revealed two ancestral groups that originated from different glacial refugia. The patterns of genetic relationships among contemporary populations largely reflect colonization histories and connections within primary and secondary watersheds.

Summary: The study on Atlantic Forest White Morpho butterflies shows that there is no clear species diversification and population structure among the populations, suggesting that the current distinction between the two species is unreasonable. Northern samples exhibit more intragroup structure, and clustering tests indicate the existence of three genetic clusters, with turnover between the states of Paran ' a and Sa similar to o Paulo.

Summary: Intense research efforts have improved our understanding of plant phylogeography and domestication in the Mediterranean basin over the past two decades. This study aimed to investigate the evolutionary history and origin of domestication of carob trees using genetic data. The findings suggest multiple origins of domestication and a west-to-east expansion of carob trees from a single refuge. The study emphasizes the importance of preserving genetic resources in wild and seminatural habitats for cultivated trees.

Summary: Traditional genotyping methods are limited in quantifying genetic diversity and structure, while next-generation sequencing has not been properly tested in highly mobile species. This study compared microsatellite and RAD-sequencing analyses in investigating population structure in the declining bent-winged bat across Europe. The results show that microsatellites were not informative in individual-based analyses, but genomic SNPs provided resolution on regional substructures and confirmed suspicions of philopatry and spatial partitioning in the species.

Summary: This study introduces a new metric, haplotype network branch diversity (HBd), which quantifiably compares haplotype network complexity by combining genetic and topological diversity. Results demonstrate that HBd can provide straightforward comparisons of network complexity and distinguish situations that are difficult to resolve with other available metrics.

Summary: The genus Capitella represents a complex of opportunistic cryptic species dominating organically enriched sediments, particularly in sulfide-rich muddy areas. Previous descriptions of Capitella species from the European Atlantic coast have been inaccurate, and their life cycle remains poorly understood despite their use as bio-indicators. This study provides the first morphological description and genetic diversification of Capitella specimens from the Brittany coast and the English Channel, supporting the presence of cryptic species in the region.

Summary: CaliPopGen is a database that provides population genetic data for native and naturalized eukaryotic species in California, USA. It summarizes published literature from 1985 to 2020 and includes a large number of populations and a wide taxonomic breadth, enabling the exploration of ecological patterns and processes in California. It is an important resource for conservation management at regional and state levels.

Summary: Habitat loss and fragmentation due to urbanization are significant contributors to the decline of biodiversity, with the western gray squirrel population in urban areas of Southern California decreasing. Griffith Park is home to one of the last urban populations of western gray squirrels in Los Angeles.

Summary: This study investigates the genetic relationship and population structure of native sheep breeds in the western Mediterranean basin, analyzing Maghrebian, Central Italian, and Venetian sheep using highly informative microsatellite markers. The results reveal the past introduction and migration history of sheep in the occidental Mediterranean basin since the early Neolithic, fitting properly to the westward Neolithic expansion argued by zooarcheological, historical, and human genetic studies.

Summary: The study identified genetically diverse and well-structured red muntjac populations in Northwestern India, with significant genetic differentiation and low gene flow. It confirmed the presence of a distinct Himalayan red muntjac lineage within the red muntjac group and recommended reassessment of their conservation status for effective management. The evolutionary history and phylogeography of red muntjacs were revealed through analysis of mitogenomes and microsatellite loci.

Summary: This paper proposes a concept drift detector that is able to detect, localize, and reason about concept drifts in both process structure and customer behavior of the control-flow. It utilizes multi-components originating from Discrete-time Markov chains and demonstrates desirable performance in experimental and real-life datasets.

Summary: The genetic structure of Aspidodera raillieti populations in the South and Southeast Atlantic Forest is mainly influenced by historical events rather than current geographical distribution or host specificity. Additionally, we found morphometric variation associated with host species and localities, suggesting phenotypic plasticity to host attributes and spatial variables.
