Annotation The research effort, publication rate and scientific community within the field of marine viruses have been growing rapidly over the past decade and viruses are now known to play key roles in microbial population dynamics, diversity and evolution as well as biogeochemical cycling. The compilation of papers included in the current Special Issue highlights the exploration of eukaryotic and prokaryotic viruses, from discovery to complex interplays between virus and host and virus-host interactions with ecologically relevant environmental variables. The discovery of novel viruses and new mechanisms underlying virus distribution and diversity exemplify the fascinating world of marine viruses. The oceans greatly shape Earth's climate, hold 1.37 billion km3 of seawater, produce half of the oxygen in the atmosphere, and are integral to all known life. In a time where life in the oceans is under increasing threat (global warming, pollution, economic use) it is pressing to understand how viruses affect host population dynamics, biodiversity, biogeochemical cycling and ecosystem efficiency.

Marine litter is defined as any persistent, manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment, and it is among the most important environmental problems which are affecting the sea nowadays. In this work, we present an integrated approach to the marine litter hot spots identification. The results come from a coordinate activity of filed campaigns, satellite monitoring and numerical model simulations. The method has been applied on the Adriatic basin as part of the MARLESS INTERREG IT-HR project.

A comprehensive guide to the fishes of the Okavango Delta and Chobe River, this book offers background information on the diverse aquatic habitats of the region and on fish feeding, breeding and survival strategies. It also provides useful hints for anglers. The species entries describe each fish in detail, with key ID points and information on habits and occurrence. Each account is accompanied by a colour illustration or photograph. The book concludes with information on how best to utilise and conserve the fishes of the delta system and Chobe River. This is the only such guide to fishes of the region and will be invaluable to local and visiting fishermen, naturalists and conservationists, as well as the many tourists who visit this spectacular African paradise.
