Preface: Emerging trends in aquatic ecology II

摘要: You are now consulting the celebratory volume 750 of Hydrobiologia, international journal aquatic sciences. The has, since its first in March 1948, exactly 67 years ago, covered a lot ground and has seen change landscape scientific publishing general, that biodiversity particular. It evolved from fairly locally managed journal, to an with ever increasing impact ranking. With ISI 2013 Impact Factor 2.212, it ranks 32 out 103 journals ‘‘Marine Freshwater Biology’’.
