The journal '[Rinsho ketsueki] The Japanese journal of clinical hematology' publishes original research contributions on marine ecology, focusing on the structure and dynamics of marine benthic and pelagic ecosystems, communities, and populations, as well as the critical links between ecology and the evolution of marine organisms. The journal prioritizes contributions that elucidate fundamental aspects of species interactions and environmental adaptations, integrating information from various organizational levels (from molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, paleontology, and modeling) from an ecological perspective. It also focuses on population genetic processes, the evolution of life histories, morphological traits and behavior, historical ecology and biogeography, macroecology and seascape ecology, paleoecological reconstruction, and ecological changes due to the introduction of new biota, human pressure, or environmental change. Most applied marine sciences, including fisheries biology, aquaculture, natural products chemistry, toxicology, and local pollution studies, fall outside the scope of the journal. Papers should address ecological questions of interest to a global readership of ecologists; papers primarily focused on local issues, including descriptions of flora and fauna, taxonomic descriptions, and range extensions, will not be considered.
