Benthic hydroids are organisms with a metagenetic life cycle involving the stages of polyp and medusa, the latter being the main stage of dispersal in Hydrozoa. Considering the historical and faunistic connectivity of the Antarctic and subantarctic regions and the changes of biogeographic patterns with different strategies of dispersal of the marine species, this project aims (1) to propose hypotheses of areas of endemism to the Antarctic and subantarctic benthic hydroids through the use of parsimony and optimization methods in biogeography, (2) to contrast the patterns found with the different strategies of life cycle in Hydrozoa. A dataset with 249 species of benthic hydroids distributed along the region between 20°S and 70°S will be used to construct presence and absence matrices according to the different type of life cycle in Hydrozoa. The matrices will be analyzed through different strategies of search using the Parsimony Analysis of Endemicity (PAE), and the Analysis of Endemicity (AE) carried out by the software NDM-VNDM. This project will be developed along 20 months, representing a large contribution to clarify the marine biogeographic patterns at the Antarctic and subantarctic regions, involving benthic organisms with different reproductive strategies. The applicant indicated has excellent qualifications to perform the project, a strong background in Hydrozoa's systematics and marine biogeography, experience with all the methods and analyses expected in the project, besides the wide knowledge concerning the biological system in question.
