Habitat spe­cial­iz­a­tion through ger­min­a­tion cueing

The import­ance of regen­er­a­tion to plant hab­itat spe­cial­iz­a­tion has been poorly stud­ied. ten Brink et al. exam­ine the adapt­ive asso­ci­ation between ger­min­a­tion eco­logy and spe­cial­iz­a­tion to either forest or open hab­it­ats in a com­par­at­ive exper­i­ment using 17 con­gen­eric spe­cies pairs with con­trast­ing hab­itat pref­er­ence. They find that seeds of forest and open hab­itat spe­cies respond dif­fer­ently to envir­on­mental cues. In a con­cep­tual model they show that spe­cies from the two hab­it­ats are adap­ted to util­ize dif­fer­ent win­dows of oppor­tun­ity in time (sea­son) and space (hab­itat), and they sug­gest that phases in the plant life cycle other than the estab­lished phase should be con­sidered import­ant in adapt­ive specialization.
