Changing attitudes toward chydorid anomopods since 1769are not the same. Attitudes are shifting away from cosmopolitanism (presumably brought about by the passive dispersal of resting eggs), to vicariant events as one of the major mechanisms affecting the evolution of the chydorids and involved in controlling their distributions.作者: champaign 時間: 2025-3-22 17:38 作者: 阻止 時間: 2025-3-22 22:17 作者: Dorsal-Kyphosis 時間: 2025-3-23 02:48
