摘要:

摘要:
, it is theorized that widespread sperm competition leads to selection for investment in sperm numbers, achieved by minimizing sperm size within limited resources

摘要:

摘要:
The evolution of sperm quality and quantity is shaped by various selective processes, with sperm competition generally considered the primary

摘要:
the mechanics of processing sperm in this species, which are likely shaped by selection on female reproductive morphology for adaptive sex allocation.
