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.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged. Specifically, the following research areas will be covered:
• Integument and effector organs (exoskeleton, muscles and glands).
• Sensory structures, peripheral, autonomic and central nervous systems, and neuroendocrine systems.
• Circulatory, respiratory, visceral, and excretory organs.
• Reproductive systems, organogenesis and repair.
• Pattern formation and development.
• Comparative microanatomy and morphology of arthropods from the phylogenetic view.
A thorough but efficient peer-review system with the assistance of section and advisory editors of world-wide reputation will ensure that published papers will conform to high scientific standards. Review articles and article series on relevant topics will be invited at regular intervals and will be subject to peer-review. Particular emphasis will be given to high quality line and half-tone illustrations. Exceptional colour plates will be printed free of charge. Supplementary 3-D and motion figures and other electronic addenda can be submitted with the manuscript and published on the journal's website after acceptance.
