Rivers around the world are threatened by changes in land use, climate, hydrologic cycles, and biodiversity. Global changes in rivers include, but are not restricted to water flow interruptions, temperature increases, loss of hydrological connectivity, altered water residence times, changes in nutrient loads, increasing arrival of new chemicals, simplification of the physical structure of the systems, occurrence of invasive species, and biodiversity losses. All of them affect the structure and functioning of the river ecosystem, and thereby, their ecosystem services. Understanding the...

The Great Barrier Reef Marine Park is 344 400 square kilometres in size and is home to one of the most diverse ecosystems in the world. This comprehensive guide describes the organisms and ecosystems of the Great Barrier Reef, as well as the biological, chemical and physical processes that influence them. Contemporary pressing issues such as climate change, coral bleaching, coral disease and the challenges of coral reef fisheries are also discussed.

In addition, the book includes a field guide that will help people to identify the common animals and plants on the reef, then to delve...

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...
