| Abstract: | Reproduction is a primary behavior and process for all organisms to multiply their descendants,and is also a research hotspot of conservation and restoration of populations in severe danger. The study on reproductive ecology is the key to solve the restoration and conservation of degraded populus euphratica forest at oasis of the extreme arid area in northwest China.The history of reproductive ecology of populus euphratica was briefly reviewed. Furthermore,the main aspects of study on reproductive ecology o... |
