Distribution
The distribution of this species is Danubian.[3]
Fehér et al. (2012)[4] revealed in their conservation genetics study, that intraspecific variability of two researched DNA markers (cytochrome c oxidase subunit I and ATP synthase subunit α) is very low.[4] They hypothesized that the bottlenecked population colonized the whole range of Theodoxus transversalis in the Holocene.[4] Fehér et al. (2012) also hypothesized that such low genetic diversity caused the high sensitivity of Theodoxus transversalis to water quality.[4] Theodoxus transversalis was widespread in Danubian drainage,[4] but the population of this species declined because of water pollution and this species is considered as endangered.[1] It is also listed in the Annexes II and IV of the Habitats Directive.[4]
