摘要: The potential influence of seed bank composition on range shifts species due to climat change is unclear. Seed banks can provide a means both persistence in an area and local rang expansion the case increasing habitat suitability, as may occur under future climate change. However mismatch between established plant community represent obstacl expansion. In big sagebrush (Artemisia tridentata) communities Montana, USA we compared community. There was less than 20% similarity i relative abundance bank. This differenc primarily driven by overrepresentation native annual forbs underrepresentatio Even though expec increase suitability for conditions at our sites, curren could impede expansio into increasingly suitable future.
