The 2nd international tagging and tracking symposium was held in San Sebastian, Spain, in October 2007, seven years after the first symposium was held in Hawaii in 2000 (Sibert and Nielsen 2001). In the intervening seven years, there have been major advances in both the capability and reliability of electronic tags and analytical approaches for geolocation of tagged animals in marine habitats. Advances such as increased data storage capacity, sensor development, and tag miniaturization have allowed researchers to track a much wider array of marine animals, not just large and charismatic...

A cohesive collection of talks from the ASLO 2009 aquatic sciences meeting, this volume explores 'disregarded' microbial eukaryote diversity and its ecological potential in aquatic ecosystems.

Rotifera are a very common group of invertebrates and, therefore, play a considerable role in the food webs of plankton and benthos of lakes and rivers worldwide. Their ecological success is based on their distinct pattern of reproduction: a large part of them, the Monogononta, are famous for their unique mode of reproduction with parthenogenetic females and a rather rare appearance of sexuality with males. On the other hand, the Bdelloidea completely abstain from sexuality. Although many life cycle characteristics make the Rotifera ideal objects for the study of important scientific and...

Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species...

Ancient lakes are exceptional freshwater environments that have continued to exist for hundreds of thousands of years. They have long been recognized as centres of biodiversity and hotspots of evolution. During recent decades, speciation in ancient lakes has emerged as an important and exciting topic in evolutionary biology.

The contributions in this volume deal with patterns and processes of biological diversification in three prominent ancient lake systems. Of these, the famous East African Great Lakes already have a strong tradition of evolutionary studies, but the two...

This is the first comprehensive science-based textbook on the biology and ecology of the Baltic Sea, one of the world's largest brackish water bodies. The aim of this book is to provide students and other readers with knowledge about the conditions for life in brackish water, the functioning of the Baltic Sea ecosystem and its environmental problems and management. It highlights biological variation along the unique environmental gradients of the brackish Baltic Sea Area (the Baltic Sea, Belt Sea and Kattegat), especially those in salinity and climate.
