Effects of predispersal insect seed predation on the early life history stages of a rare cold sand-desert legume

Abstract Seed predation by insects is common in seeds of Fabaceae (legume) species with physical dormancy (PY). However, the consequences of insect seed predation on the life history of legumes with PY have been little studied. In the largest genus of seed plants, Astragalus (Fabaceae), only one stu...
