SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

CBP publishes papers in comparative, environmental and evolutionary physiology. Part A: Molecular and Integrative Physiology focuses on physiological systems, including behavior, circulation, development, excretion, ion regulation, endocrinology, locomotory, nervous, nutrition, respiration, and thermal biology. Most studies address regulatory mechanisms and span multiple levels of biological organization.
Comparative Biochemistry & Physiology, with its four journals, receives editorial direction from all the major societies in the field (European Society for Comparative Physiology and Biochemistry, the Japanese Society for Comparative Physiology and Biochemistry, Canadian Society of Zoologists (CBP Section), the Society for Experimental Biology, the Society for Integrative and Comparative Biology (formerly the American Society for Zoologists), the Australian and New Zealand Society for Comparative Physiology and Biochemistry, the South American Society for Comparative Physiology & Biochemistry, the Russian Physiological Society, and the Chinese Association for Physiological Sciences)
