Global climate change affects productivity and species composition
of freshwater and marine aquatic ecosystems by raising
temperatures, ocean acidification, excessive solar UV and visible
radiation. Effects on bacterioplankton and viruses, phytoplankton
and macroalgae have farreaching consequences for primary consumers
such as zooplankton, invertebrates and vertebrates, as well as on
human consumption of fish, crustaceans and mollusks. It has
affected the habitation of the Arctic and Antarctic oceans the most
so far. Increasing pollution from terrestrial runoff, industrial,
municipal and household wastes as well as marine transportation and
plastic debris also affect aquatic ecosystems.
Automatic image analysis has become an important tool in many fields of biology, medicine, and other sciences. Since the first edition of Image Analysis: Methods and Applications, the development of both software and hardware technology has undergone quantum leaps. For example, specific mathematical filters have been developed for quality enhancement of original images and for extraction of specific features of interest. Also, more complex programs have been developed for the analysis of object forms in distinguishing cancer cells from normal tissue cells. Just as significant, three-dimensional analysis of proteins, organelles, or macroscopic objects is even more complex. In addition, recent space-based experiments have optimized techniques for the extraction of movement parameters of numerous motile objects.
The second edition of Image Analysis: Methods and Applications addresses all these new developments. Moreover, two new chapters have been added. One focuses on images on the internet, and the other discusses microscope image restoration. These chapters add significantly to the existing body of information on Internet communication protocol and environment as well as to that on image file formats considerations. The materials also include a list of internet Web sites that pertain to digital images and software along with those that relate to image processing.
With these considerations in mind, Image Analysis: Methods and Application, Second Edition is of incalculable value to professionals, academics, and users of all aspects of image analysis in biology and other areas of science.
During the last few decades anthropogenic activities in the
industrially advanced countries have outcompeted nature in changing
the global environment. This is best illustrated for example by the
polluted lakes in Scandinavia and Canada, associated with acid
deposition from fossil fuel combustion. One of the major challenges
mankind is confronted with in the field of energy consumption is
undoubtedly to ensure sustainability - a goal that requires
improved management of natural resources and a substantial
reduction of the noxious emissions which are dangerous to health
and the environment. The threat of global climate change due to
pollutant emissions causes se rious concern to many nations, and
reaching an international consensus is likely to take some time.
Carbon dioxide emissions have slowed only marginally in
industrialized countries during the last few years, but have
increased significantly in most developing countries due to
increases in energy demand and the increasing use of fossil fuels,
which remain the most readily available energy sources today.
Unfortunately, far from learning lessons from the negative
experiences of developed countries, many developing countries are
taking the same path to development which has turned out to result
in serious environmental consequences."

Natural Bioactive Compounds: Technological Advancements deals with
the latest breakthroughs in the field of screening,
characterization and novel applications of natural bioactive
compounds from diverse group of organisms ranging from bacteria,
viruses, cyanobacteria, algae, fungi, bryophytes, higher plants,
sponges, corals and fishes. Written by some of the most reputed
scientists in the field, this book introduces the reader to
strategies and methods in the search for bioactive natural
products. It is an essential read for researchers and students
interested in bioactive natural products, their biological and
pharmacological properties, their possible use as chemopreventive
or chemotherapeutic agents, and other future potential
applications.
