Using a molecular approach and High Throughput Sequencing (HTS) technologies, Dr. Poliseno explored the intra-specific diversity and population structure of the Atlantic-Mediterranean zoantharian Savaglia savalia. Dr. Poliseno investigated the genetic diversity of the Indo-Pacific sponge associated zoantharian Umimayanthus and their hosts. Finally, given the high abundance and diversity observed in the field, the fellow conducted a biodiversity survey of the gorgonian octocorals collected from Okinawajima island and other islands of southern Japan.For population genomics of Savalia savaglia Dr. Poliseno found that individuals collected from 5 geographical distinct areas across the Mediterranean basin (France, Montenegro, Apulia and Sardinia - Italy) and eastern Atlantic (Portugal) grouped into three distinct clusters. Our results showed that asexual reproduction may possibly explain the presence of clonal individuals within some populations. Dr. Poliseno did not find any correlation between geographic distance and genetic structure, whereas we observed that populations at greater depths are genetically more similar, whereas those from shallower areas are very distinct from each-other.The analyses on the diversity of the sponge associated zoantharian Umimayanthus and their hosts suggest the lack of species-specific association. In particular Dr. Poliseno found that, for the specimens investigated, the sponges associated with Unimayanthus belong to at least five genera (e.g. Agelas, Clathria, Cliona, Hymeniacidon and Spirastrella).

使用分子方法和高通量测序（HTS）技术，Poliseno博士探索了南极-地中海动物园Savaglia萨瓦利亚的种内多样性和种群结构。Poliseno博士调查了与印度-太平洋海绵相关的zoantharian Umimayanthus及其宿主的遗传多样性。最后，鉴于在野外观察到的高丰度和多样性，该研究员对从冲绳本岛和日本南部其他岛屿收集的柳珊瑚进行了生物多样性调查。对于萨瓦利亚savaglia的种群基因组学，Poliseno博士发现，从地中海盆地的5个地理不同地区收集的个体（法国、黑山、阿普利亚和撒丁岛-意大利）和东大西洋（葡萄牙）分为三个不同的集群。我们的研究结果表明，无性繁殖可能解释克隆个体在某些群体中的存在。Poliseno博士没有发现地理距离和遗传结构之间的任何相关性，而我们观察到，在更深的深度种群的遗传更相似，而那些从较浅的地区是非常不同的彼此。对海绵相关zoantharian Umimayanthus和它们的主机的多样性分析表明，缺乏物种特异性的关联。特别是，Poliseno博士发现，对于研究的标本，与Unimayanthus相关的海绵至少属于五个属（例如Agelas，Clathria，Cliona，Hymeniacidon和Spirastrella）。
