Orthodontics & Craniofacial Research - Genes, Growth and Development is published to serve its readers as an international forum for the presentation and critical discussion of issues pertinent to the advancement of the specialty of orthodontics and the evidence-based knowledge of craniofacial growth and development. This forum is based on scientifically supported information, but also includes minority and conflicting opinions.

Orphanet Journal of Rare Diseases《罕见病孤儿杂志》（一年1卷）. Orphanet Journal of Rare Diseases is an open access, peer-reviewed journal that encompasses all aspects of rare diseases and orphan drugs. The journal publishes high-quality reviews on specific rare diseases. In addition, the journal may consider articles on clinical trial outcome reports, either positive or negative, and articles on public health issues in the field of rare diseases and orphan drugs. The journal does not accept case reports which do not present clinical or pathological findings that can provide information about the mechanisms of a disease. Case reports which just present phenotype information, should not be considered.

Ornitologia Neotropical《新热带鸟类学》（半年刊）. The ornithological journal Ornitología Neotropical is a premier journal for scientific research on birds and their habitats in the Neotropical Region. Peer-reviewed papers are published in Spanish, Portuguese, and English. Articles from our journal are frequently cited other research journals, books, and academic publications.

Ornithology Research《鸟类学研究》（季刊）. We publish original reseach papers, short-communications and reviews related to the biology of birds, with an emphasis on documentation, analysis, and interpretation of field and laboratory studies, presentation of new methodologies, theories or reviews of ideas or previously known information. Ornithology Research has a focus on the Neotropical region, but it is open to global studies on birds.

Ornithological Science《鸟类学科学》（半年刊）. Ornithological Science is published twice a year by the Ornithological Society of Japan (OSJ). The journal offers a forum for scholarly papers on the avifaunas of Japan, Asia, and other parts of the world. Contributions are classified as: Original Articles, Reviews, Short Communications, Technical Notes, and Comments. Purely descriptive studies containing important, new information on poorly known species or phenomena are also acceptable. Comments are limited to those on papers previously published in Ornithological Science. The OSJ editors also welcome proposals for themed Special Features that are within the scope of the journal. Membership of OSJ is not required for contributors.

Ornithological Applications《鸟类学应用》（季刊）. Ornithological Applications is a peer-reviewed journal that publishes original research, syntheses, and assessments from all parts of the globe focusing on the application of scientific theory, ornithological knowledge, and methods to the conservation and management of birds and to policy. Ornithological Applications also seeks social science studies and interdisciplinary papers: those that integrate biological, social, and/or economic data to document the value of ecosystem services provided by birds, the consequences of particular conservation actions, or the impact of energy projects on birds.

Ornis Fennica《芬兰雀鸟》（季刊）. Ornis Fennica is a peer-reviewed international ornithological journal published by BirdLife Finland. Ornis Fennica publishes analytical and experimental papers on the ecology, behaviour and biogeography of birds. We prefer studies concerning Fennoscandian species, but other novel contributions of general interest are most welcome as well.

Discover Life《探索生命》（一年1卷）. Discover Life is a fully open access, peer-reviewed journal that supports multidisciplinary research and policy developments across all fields relevant to life science. The journal aims to be a resource for researchers, policy makers and the general public for recent advances in life science, and its uses in research development and society. As a fully open access journal, we ensure that our research is highly discoverable and instantly available globally to everyone. The journal particularly welcomes work that aims to address the United Nations Sustainable Development Goals, especially, Good Health and Well-Being; Life below Water, Life on Land.
