Описание: Plants are autotrophs and sessile, while animals are heterotrophs and motile. Sessility has imposed on plants 94% hermaphroditism, 23% selfing, 3% polyploidization and 39% clonality, in comparison to < 5% herma-phroditism, < 1% selfing and 2% clonality in motile animals.

Описание:
The knowledge of metal ion speciation is essential for predicting the exact toxicities of metal ion species in the environment. Metal ions can exist in various oxidation states, each of which possesses different physical and chemical properties as well as exhibit varying toxicities. Often, toxicity data is unreliable because it is based on metal ion concentration measurements that fail to identify a dominant species either more or less harmful than the average. Instrumental Methods in Metal Ion Speciation provides analytical techniques and experimental methodologies for determining the concentration of the different physicochemical forms of metal ions in environmental and biological samples, leading to more accurate measurements of actual toxicity.
The authors introduce the principles of metal ion speciation and discuss important analytical techniques such as gas and liquid chromatography, capillary electrophoresis, and both electrochemical and radiochemical methods used to determine concentration and composition. They present a range of liquid chromatographic approaches, including capillary electrochromatography and high-performance, ion, ion pair, micellar electrokinetic, size exclusion, chiral, and supercritical fluid chromatographies for all metal ion species. Comprehensive in scope, the text covers the sources, distribution, toxicity, biotransformation, and biodegradation of each metal ions species as well as extraction methods, sample preparation, and experimental optimization techniques that can be useful in designing future experiments.
Instrumental Methods in Metal Ion Speciation is a unique and valuable source of reference for scientists, academics, and researchers involved in analytical, biological, pharmaceutical, and environmental chemistries, as well as material industries, geochemistry, agriculture, biotechnology, and occupational safety and regulations.

Описание: This book documents and interprets the onshore Cenozoic temperate carbonate depositional system along the southern margin of Australia. These strata, deposited in four separate basins, together with the extensive modern marine system offshore, comprise the largest such cool-water carbonate system on the globe.

Описание: This book provides essential information on 12 cockroach assemblages with more than a thousand specimens analyzed and investigates the Jurassic site in Bakhar, Mongolia, as one of the most diverse fossil insect sites worldwide. The findings presented here include 32 new cockroach species (of a total of 300 Jurassic species described worldwide).
Описание: Composting is one of the popular methods in waste management and there are a lot of issues pertaining to composting. One of it is the leaching of heavy metals. This book discusses thoroughly, the availability, leachability and the speciation of heavy metals in the entire process of composting.

Описание:
These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty.
A departure from mainstream biology, the idea of symbiosis -- as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals -- has attracted the attention of a growing number of scientists.
These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal-bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution.
