Diel Vertical Migration of Zooplankton in Lakes and Oceans by Joop Ringelberg Pdf

Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10–40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of “Krill” may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.

Limnology in Australia by P. de Deckker,W.D. Williams Pdf

Australia is the world's driest inhabited continent. Water is our limiting resource. It might therefore be thought that our water resources would be the subject of the most intensive study. Certain aspects, it must be conceded, have received much attention, notably the availability of water in terms of actual quantity. The size of the surface water and the groundwater resource is well understood and indeed receives about as much study as can reasonably be expected in a country with as sparse a population and level of scientific manpower as ours. Although the importance of understanding the water resource in terms of quantity is widely accepted, what has not been generally appreciated is that for this resource to be 'available' to human society for all the different uses to which it is put, it is not sufficient that there exists within easy reach of the end users a certain total volume of water. For that water to fulfil its functions-for agriculture, industry, the home, recreation, biological conservation-it must be in a certain state: it must conform to certain chemical, physical and biological criteria, and what has not been sufficiently appreciated in Australian society is that the condition a water is in depends very much on the ecology of the waterbody in which it resides. There are waterbodies in the world, for example high-altitude glacial lakes, which are naturally so pristine that their water could be used for any purpose without treatment.

Life Histories by Martin Thiel,Gary A. Wellborn Pdf

Crustaceans are increasingly being used as model organisms in all fields of biology, including neurobiology, developmental biology, animal physiology, evolutionary ecology, biogeography, and resource management. Crustaceans have a very wide range of phenotypes and inhabit a diverse array of environments, ranging from the deep sea to high mountain lakes and even deserts. The evolution of their life histories has permitted crustaceans to successfully colonize this variety of habitats. Few other taxa exhibit such a variety of life histories and behavior. A comprehensive overview of their life histories is essential to the understanding of many aspects of their success in marine and terrestrial environments. This volume provides a general overview of crustacean life histories. Crustaceans have particular life history adaptations that have permitted them to conquer all environments on earth. Crustacean life cycles have evolved to maximize fecundity, growth, and ageing, in a wide range of environmental conditions. Individual contributions contrast benefits and costs of different life histories including sexual versus asexual production, semelparity versus iteroparity, and planktonic larvae versus direct development. Important aspects of particular behaviors are presented (e.g. migrations, defense and territorial behaviors, anti-predator behavior, symbiosis).

Real-time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms by Babin, Marcel,Roesler, Collin S.,Cullen, John J. Pdf

The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Spawning Migration of the European Eel by Guido van den Thillart,Sylvie Dufour,J. Cliff Rankin Pdf

Freshwater eels are almost infinitely improbable creatures. They spawn and die in the middle of the ocean, often associated with undersea mountains. Their tra- parent, leaf-like larvae move with ocean currents for months or years until they approach the mouths of freshwater rivers. Then they undergo a dramatic transf- mation in morphology, physiology and behavior. They move from their planktonic oceanic environment, migrate upstream and live for several years as apex fre- water predators. Then, almost impossibly, as they become sexually mature, they reverse their migration downstream to the ocean and back to spawning grounds to complete their life cycle. The dramatic changes in their life cycles are incredible. The efforts to unravel the details of their life history have been truly daunting. Much of the past research was the work of dedicated individuals who devoted their lifetime research to these fishes. Freshwater eels merit a separate chapter in almost any textbook dealing with ichthyology, marine biology or animal migration. We know a great deal about some aspects of the biology of freshwater eels. However, our understanding of their bi- ogy still resembles a work of art as much as a work of science. To some it appears like the sweeping brush strokes of a Japanese Zen landscape, to others it resembles the work of a French impressionist, and to still others it appears as magic realism.

Chemical Ecology in Aquatic Systems by Christer Brönmark,Lars-Anders Hansson Pdf

In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.

Bidong Island by Ong Meng Chuan,Melissa Beata Martin,Mohd Yusoff Nurulnadia,Wahizatul Afzan Azmi Pdf

Bidong Island is a small island located in the South China Sea, and is about 14 km from mainland Peninsular Malaysia. The island and the Bidong archipelago boast of its richness in diversity of both terrestrial and marine organisms and its undeniably pristine and thriving ecosystem. In 1975–1990, Bidong Island was formerly a UNHCR refugee camp for a quarter of a million Vietnamese "Boat people" escaping the Vietnam War, and still holds great significance to many of its descendants. Due to its historical significance, the Terengganu State government plans to develop Bidong Island as a heritage tourism site and a new scuba diving destination. This book highlights the uniqueness of Bidong Island and its archipelago, paying particular attention to the biological aspect (which includes marine and terrestrial organisms) and the pollution status surrounding the island. These mainly focus on organisms of the open water and benthic ecosystems such as plankton, fishes, corals reef communities, crustaceans and foraminifera. In addition, we discuss terrene related topics, which includes tree diversity, lichens and also herpetofauna surrounding the Bidong Island. Indisputably an important topic, we also address the pollution status surrounding Bidong Island, with emphasis on heavy metals and its impact. Readers interested in the areas of environmental sciences should find this book appealing. This book can also be used by students and researchers when discussing about tropical environments on island ecosystems. We do hope that stakeholders that would partake in future interest of Bidong Island (particularly in tourism) are equally aware of the current health status of the island and would engage in conserving and sustaining the diversity and heritage of the archipelago for the benefit of the community.

Arctic Ecology by David N. Thomas Pdf

The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.
