Distribution and ecology of freshwater Ostracoda (Crustacea) collected from springs of Nevada, Idaho, and Oregon: a preliminary study
(Brigham Young Univ, 2000) Külköylüoğlu, Okan; Vinyard, Gary L.
Fourteen freshwater ostracod species collected from 24 springs ill Nevada, Idaho, and Oregon between 1991 and 1994 were classified. Their ecology; based on major water parameters (i.e., temperature, dissolved oxygen, pH, conductivity), and biogeographical distribution in North America were studied. Among these 14 species, 9 (Ilyocypris bradyi, I, gibba, Darwinula stevensoni, Candona candida, Heterocypris incongruens, Herpetocypris reptans, H. chevreuxi, Prionocypris canadensis, P. longiforma) are new records for Nevada's ostracod fauna, while 3 (H. reptans, Il canadensis, and Cypria turneri) are new species for Oregon. H, reptans, P. canadensis, and Heterocypris salina are also recorded as new for the ostracod literature of Idaho. Scottia pseudobrowniana, collected from Nevada, is a new ostracod species for the United States. The occurrence of 5 Holarctic species in the northern Great Basin area ma!: suggest a possible historical relationship with the European ostracod fauna.
