Article Synopsis
- The study focuses on the diverse species flocks in ancient lakes, particularly highlighting freshwater gastropods from Sulawesi, which are known for their unique evolutionary adaptations.
- Utilizing next-generation sequencing, researchers gathered a comprehensive dataset of mitochondrial genomes from 78 individuals, including most morphospecies of Tylomelania in the Malili lake system.
- The findings suggest that, while mitochondrial genomes provide more data, they often behave like a single locus, limiting their effectiveness in resolving complex species relationships, especially in cases of rapid diversification and mitochondrial introgression.
Article Synopsis
- Extinction rates are rising, but conservation resources are limited, prompting a focus on prioritizing unique species for protection based on their evolutionary and ecological significance.* -
- Researchers analyzed historical DNA from an old specimen of the rare snail species Helicostoa sinensis, revealing its unique evolutionary traits and confirming its classification as an ultra-rare taxon within the Bithyniidae family.* -
- The study emphasizes the urgent need for conservation efforts that recognize and preserve the originality of invertebrate species, particularly in unique and extreme environments like river rapids.*
The distribution of the five (Gastropoda, Truncatelloidea, Amnicolidae) species that are diagnosed by both morphological and molecular data is combined with several records of less completely diagnosed nominal species. The resulting distribution pattern is summarized in a map and is discussed herein. is described from Bhutan on the basis of shell morphology and two mitochondrial DNA barcoding markers.

Numerous studies have proposed different sets of biotic and abiotic controls of speciation and extinction rates, but typically they were inferred for a single, long geological time frame. However, whether the impact of biotic and abiotic controls on diversification changes over time is poorly understood.
