WELCOME ADDRESS Dear participants and delegates Lomonosov Moscow State University and the Paleontological Institute of Russian Academy of Sciences welcome you to the 4th International Congress on Invertebrate Morphology (ICIM4). The diverse and fascinating world of invertebrate animals always attracted interest of zoologists. However, it was not until just ten years ago when scientists created an international society in the field of Invertebrate Morphology. The society has been a true example of a grassroots movement -- scientists for no other reason than mere interest came together to exchange results, share ideas and technical advances within their studies of this amazing diversity of invertebrates and forms of their adaptation. Until now the Society runs without a large administrative body and relies primarily on the passion of volunteers. After the inaugural congress in Copenhagen (Denmark) in 2008, Cambridge, (USA, 2011) and Berlin (Germany, 2014) the fourth Congress will be held in Moscow, Russia in August 18 – 23, 2017. The Moscow Congress will consist of 14 Symposia reflecting actual vectors of invertebrate morphology. The focus of the 4th Congress will be on (i) synthesis of classical morphology with advances in molecular taxonomy and phylogeny; (ii) evolutionary developmental biology; (iii) investigations on structure of different groups of invertebrates, in particular, parasites; (iv) comparative analysis of the system as nervous, circulatory and excretory; (v) the problem of miniaturization and the evolution of larval forms; and (vi) modern achievements in the field of functional morphology and paleontology. Special attention has been paid to modern approaches and methods of morphological and evolutionary studies. One of the main goals of the ICIM4 is to provide a platform for communication and facilitate international collaboration of young researchers. More than 300 participants from 25 countries made their plans to take part in the ICIM4, Moscow. We thank everyone who contributed presentations on different aspects of invertebrate morphology, especially our keynote speakers and invited lectors! We express our gratitude to sponsors , without their support we wouldn’t be able to afford this gathering in Moscow. And let me to express a big ‘thank you’ to everyone involved behind the scenes! I extend my best wishes to all of you and hope you have fruitful discussions and memorable time in Moscow. Natalia M.
