Aquatic Sciences - Research Across Boundaries publishes original research, overviews, and reviews dealing with aquatic systems (wetlands, freshwater and marine systems) and their boundaries, including the impact of human activities on these systems. The coverage ranges from molecular-level mechanistic studies to investigations at the whole ecosystem scale, including fish ecology. Aquatic Sciences publishes articles presenting research across disciplinary and environmental boundaries, i.e. studies examining interactions among geological, microbial, biological, chemical, physical, hydrological, and societal processes, as well as studies assessing land-water, air-water, benthic-pelagic, river-ocean, lentic-lotic, and groundwater-surface water interactions.
