The Mitochondrial Genome of Melipona fasciculata (Apidae, Meliponini): Genome Organization and Comparative Analyses, Phylogenetic Implications and Divergence Time Estimations.
Biochem Genet
December 2024
The native stingless bee Melipona fasciculata is economically and ecologically important to the Brazilian Northeast, providing a sustainable source of income to family farmers and being considered an effective pollinator in most ecosystems and crops. This study describes, for the first time, the mitogenome of the species and its phylogenetic position. The mitochondrial genome was sequenced using a MiSeq Sequencer (Illumina Inc.

- Complex traits like age at maturation in Atlantic Salmon involve complex genetics influenced by evolutionary variations and different types of genetic sweeps.
- Research on North American Atlantic Salmon suggests a genetic parallel to European populations with identified large-effect loci, but variations exist based on sex and geographic location.
- Despite low levels of genetic similarity across populations, consistent molecular pathways related to sea age have been identified, highlighting a mix of shared and unique genetic influences.
Conservation units represent important components of intraspecific diversity that can aid in prioritizing and protecting at-risk populations, while also safeguarding unique diversity that can contribute to species resilience. In Canada, identification and assessments of conservation units is done by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). COSEWIC can recognize conservation units below the species level (termed "designatable units"; DUs) if the unit has attributes that make it both discrete and evolutionarily significant.

At present, little is known regarding population structure and diversity of wild lumpfish in Atlantic Canada, limiting attempts to assess the potential impacts of escaped lumpfish individuals from salmon pens on currently at-risk wild populations. Here, we characterize the spatial population structure and genomic-environmental associations of wild populations of lumpfish throughout the Northwest Atlantic using both 70K SNP array data and whole-genome re-sequencing data (WGS).

- - Environmental variation plays a crucial role in the diversity of marine species like cunner, a temperate reef fish, yet there is limited understanding of how genomic and ecological factors shape their populations.
- - A comprehensive genome assembly of cunner revealed significant genetic variation across 803 individuals from 20 locations and indicated the existence of four regional population groups in the Northwest Atlantic.
- - Findings suggest that environmental factors, particularly benthic temperature and oxygen levels, influence genetic structure, providing valuable insights for the management and conservation of cunner in aquaculture and wild settings.
