Predicting competitive shifts and responses to climate change based on latitudinal distributions of species assemblages.

abstract：:Theory predicts that reproduction will change as individuals near the end of their lives by either increasing reproductive allocation (terminal allocation hypothesis) or decreasing allocation (senescence hypothesis) toward the end of life. Although senescence has received more support, few studies examine how both age...
