Ecological Risk Screening Summary - Dikerogammarus aralychensis (an amphipod, no common name) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

Dikerogammarus aralychensis is an amphipod native to the Caucasus basin. Very little information was found on D. aralychensis, other then a general range description and a vague short description. D. aralychensis has not been found outside of its native range and no information on a potential trade history was found. The history of invasiveness is therefore classified as No Known Nonnative Population. The Climate 6 score for D. aralychensis was High, with the Great Lakes States and the Rocky Mountain range having the highest match. The certainty of assessment is Low because of the general lack of information found for this species and the absence of a history of invasiveness. The overall risk assessment category for D. aralychensis is Uncertain.
