Constructive Approximation《构造逼近》（双月刊）. Constructive Approximation is an international mathematics journal dedicated to Approximations and Expansions and related research in computation, potential theory, function theory, functional analysis, interpolation spaces and interpolation of operators, numerical analysis, space of functions, special functions, and applications.

Construction and Building Materials《结构与建筑材料》（一年48期）. Construction and Building Materials provides an international forum for the dissemination of innovative and original research and development in the field of construction and building materials and their application in new works and repair practice. The journal publishes a wide range of innovative research and application papers which describe laboratory and to a limited extent numerical investigations or report on full scale projects. Multi-part papers are discouraged.

Constraints《约束》（季刊）. Constraints provides a common forum for the many disciplines interested in constraint programming and constraint satisfaction and optimization, and the many application domains in which constraint technology is employed. It covers all aspects of computing with constraints: theory and practice, algorithms and systems, reasoning and programming, logics and languages.

Conservation Science and Practice《保护科学与实践》（月刊）. Conservation Science and Practice publishes papers that address the policy, planning, and practice of conserving biological diversity. The journal publishes papers that expand conservation knowledge ranging from practical experience to advances in theory. The journal places special emphasis on studies that connect findings to conservation outcomes to address which strategies work as well as which strategies fail. Studies with implications for biodiversity conservation applications that rely on established methods on specific case studies are welcome, including those that do not transcend species, ecosystem, or situation.

Conservation Physiology《保护生理学》（一年1卷）. Conservation Physiology is an online only, fully open access journal published on behalf of the Society for Experimental Biology. Biodiversity across the globe faces a growing number of threats associated with human activities. Conservation Physiology publishes research on all taxa (microbes, plants and animals) focused on understanding and predicting how organisms, populations, ecosystems and natural resources respond to environmental change and stressors.

Conservation Letters《保护快报》（双月刊）. Conservation Letters is a scientific journal publishing empirical and theoretical research with significant implications for the conservation of biological diversity. The journal welcomes submissions across the biological and social sciences - especially interdisciplinary submissions – that advance pragmatic conservation goals as well as scientific understanding. Manuscripts will be published on a rapid communications schedule and therefore should be current and topical. Research articles should clearly articulate the significance of their findings for conservation policy and practice.

Conservation Genetics Resources《保护遗传学资源》（季刊）. Conservation Genetics Resources promotes the conservation of genetic diversity and advances the study of conservation genetics by publishing technical papers and reviews on methodological innovations or improvements, computer programs, and genomic resources, as well as on the practical application of these resources towards the development of effective conservation policy and practice.

Conservation Genetics《保护遗传学》（双月刊）. Conservation Genetics promotes the conservation of biodiversity by providing a forum for data and ideas, aiding the further development of this area of study. Contributions include work from the disciplines of population genetics, molecular ecology, molecular biology, evolutionary biology, systematics, forensics, and others. The focus is on genetic and evolutionary applications to problems of conservation, reflecting the diversity of concerns relevant to conservation biology.

Conservation Biology《保护生物学》（双月刊）. Conservation Biology is the most influential and frequently cited journal in its field. The journal publishes groundbreaking papers and is instrumental in defining the key issues contributing to the science and practice of conserving Earth’s biological diversity.

Connective Tissue Research《结缔组织研究》（双月刊）. The aim of Connective Tissue Research is to present original and significant research in all basic areas of connective tissue and matrix biology. The journal also provides topical reviews and, on occasion, the proceedings of conferences in areas of special interest at which original work is presented.
