Revealing potential mechanisms of native and non-native snail coexistence through fecal microbiomes and dietary compositions.

Understanding how animals coexist within an ecosystem is essential for the conservation of biodiversity. In China, large populations of a non-native snail Rumina decollata (a highly invasive species reported by various other countries) coexist with two native snail species (Acusta ravida and Euphaedusa aculus). However, the potential mechanisms that facilitate this non-native and native snail coexistence remain uncertain.

Characterization of the complete mitochondrial genomes of four tarantulas (Arachnida: Theraphosidae) with phylogenetic analysis.

To better understand the evolution of mitochondrial genomes (mitogenomes) within the family Theraphosidae, we characterized mitogenomes of four tarantulas (Grammostola pulchripes, Phormictopus atrichomatus, Pterinochilus murinus and Pterinopelma sazimai) for the first time. The mitogenomes were all classical circular structures, with lengths ranging from 13,822 bp to 14,011 bp. The constitutive genes and the orientation of the coding strand observed in the four mitogenomes were consistent with those found in other species belonging to the Theraphosidae family.

Complete Mitochondrial Genomes of Pencilfish: Genome Characterization and Phylogenetic Analysis.

Although the pencilfish is a globally popular economic fish in the aquarium market, its taxonomic classification could be further refined. In order to understand the taxonomy of species of the genus (Characiformes, Lebiasinidae) and their phylogenetic position within the order Characiformes, in this study, we characterized mitochondrial genomes (mitogenomes) from four species for the first time. The four mitogenomes exhibited the typical circular structure, with overall sizes varying from 16,661 bp to 16,690 bp.

Complete Mitochondrial Genomes of : New Insights into the Color Polymorphism of Millipedes.

There has been debate about whether individuals with different color phenotypes should have different taxonomic status. In order to determine whether the different color phenotypes of require separate taxonomic status or are simply synonyms, here, the complete mitochondrial genomes (mitogenomes) of two different colored , i.e.
