Diversity & Population Ecology of Rocky Intertidal Mollusca

The ocean covers about 70% of earth’s surface and is great reservoir of life. The study which deals with the marine and coastal habitat and its organisms is known as Marine and Coastal ecology. Ecology is the scientific discipline of understanding interactions between living organisms and their environment. Ecology is also the study of ecosystems with their network of complex interactions and mutual relationships between plants, animals, microorganisms and their surrounding environment. The application of ecological knowledge spans conservation and protection of animals and plants in their natural environment, the restoration of natural habitats, and management of natural resources. The current research trend includes ecology of invasive species, the link between ecology and the physical properties of the water and the marine environment, taxonomy and biodiversity, as well as the effects of human activities and climate change.

The Summary of the Principle of Optimal Diversity of Biosystems

The paper summarizes the principle of optimum diversity of biosystems, which suggests that biodiversity is a parameter to be optimized. In fact, diversity is considered as a major adaptation of biosystems to environmental conditions. Paper discusses the diversity of two hierarchical levels - population (phenotypic diversity within a population) and coenotic (number of species in community). Нypotheses about mechanisms of diversity optimisation in the ecological, microevolutionary and evolutionary processes and findings for environmental management and biodiversity conservation are considered.

The Ecology of Rodents and Shrews of Chilalo-Galama Mountains Range

The majorities of African mammals are small mammals although their ecology is least studied due to their small size, nocturnal in activity, shyness and secretive habit. From mammalian orders, rodents and shrews (excluding bat) have the largest number of species. For instance, rodents account for about 50% of mammalian species in the world; nearly 28% in East Africa; and 30% in Ethiopia and 50% of the Ethiopian endemic mammal fauna. Despite of high species diversity of rodents and shrews in Ethiopia, only few studies were carried out on their population, taxonomy and ecology. Moreover, today they are declining due to habitat loss and fragmentation resulted from anthropogenic activities. This is also true for small mammals of Mount Chilalo and Galama Mountains Range. In view of this, the book presents the ecological investigations of rodents and shrews of Mount Chilalo and Galalma Mountains Range in detail. Particularly issues on species composition, distribution, relative abundance, habitat association and seasonal population dynamics were covered in depth. The book is particularly helpful for who have interest on the ecology of small mammals of Afromontane and Afroalpine habitats.

MAPPING OF AQUATIC INSECT SPECIES DIVERSITY OF LENTIC WATER BODIES

The scenario of aquatic insect species diversity present in lentic water bodies has been amazing. Both temporal and spatial variation have been recorded in the different diversity profile of aquatic insects indicating considerable interference by human society and natural conditions. Different orders of insects being integral members of lentic water bodies have also caused surprising variation in their species richness, abundance, evenness and dominance.This has given rise to portfolio effect of the species distribution in which the individuals variation is greater as compare to community variation which is lowest and vice versa. Varying numerical data of diversity information statistics supportive of correlated heterogeneous population dynamics of aquatic insects achieved though this investigation proved as mathematical server for mapping the species diversity status of aquatic insects in this water bodies. Nevertheless species diversity maps both at community level Subject to unpredictable variation because of the fact that the quantum of individual diversity is inversely related to that of community population.

Population Structure of Oryza sativa Landraces under Farmer Management

The present study demonstrated farmer management of crop population structure and temporal evolution of rice genetic diversity in traditional production systems. The 16 STMS primers analyzed for 11 rice landrace populations indicated enough polymorphism to fully differentiate the inter- and intra-population diversity. A total number of 98 alleles were recorded of which 91 were common and 7 were rare. The mean number of alleles per locus was 6.12 and for different groups of rice landrace populations, namely five populations of upland common landrace Jaulia, three populations of irrigated common landrace Thapachini and one population each of three distinct rare landraces were 4.37, 2.75 and 4.37, respectively. The study revealed greater number of alleles per locus for on-farm managed populations as compared to the populations under static management. Further, the rare landrace populations included in the present study were more diverse than the common landrace populations. Investigating the population genetic structure is therefore helpful in monitoring change in diversity over time and space, and also for devising a rational plan for management of farmer landraces on-farm

Peter Morin J. Community Ecology

Community ecology: the study of the patterns and processes involving two or more species – has developed rapidly in the last two decades, driven by new and more sophisticated research techniques, advances in mathematical theory and modeling, and the increasing pressure on the environment wrought by humans. Once a purely descriptive science, it is now one of the most forward-looking areas of scientific inquiry. Morin skillfully guides the reader through the main tenets and central concepts of community ecology – competition, predation, food webs, indirect effects, habitat selection, diversity, and succession. In an attempt to introduce the reader to the most balanced coverage possible, Morin includes examples drawn from both the aquatic and terrestrial realm and from both plant and animal species. Balancing theory with experimentation and drawing on exciting new studies to complement the historical foundations of the discipline, he also stresses that both the empirical and theoretical approaches are necessary to drive ecology foward into the new millenium. The final chapter on applied community ecology ably demonstrates how community ecological processes have a wide environmental relevance. Although in its infancy, the application of community ecology to emerging problems in human-dominated ecosystems could mitigate problems as diverse as management strategies for important diseases transmitted by animals and the restoration and reconstruction of viable communities. Required reading for all students and practitioners interested in community phenomena, Community Ecology marks an important contribution to the development of this protean discipline. The first serious textbook for a decade on one of the keystone subdisciplines of ecology. Broad taxonomic and habitat coverage. Section on implications of community ecology for environmental issues.

Optical Remote Sensing of Microphytobenthic Primary Productivity

The relative contribution of microphytobenthic (MPB) primary productivity to the total primary productivity of intertidal ecosystems is largely unknown. The possibility to estimate MPB primary productivity would be a significant contribution to a better understanding of the role of intertidal mudflats for ecosystem functioning. Despite MPB primary productivity in intertidal sediment surfaces having an undisputable ecological role, methods of its quantification have proven to be difficult and cumbersome hence posing problems in monitoring and coming up with possible management strategies. Currently, the knowledge on MPB primary productivity in intertidal mudflats of the Dutch Wadden Sea is rudimentary. This limitation is attributed to a number of factors. Consequently, methods that will capture the spatial and temporal variations of MPB such remote sensing provide a platform for understanding MPB primary productivity. The inherent intertidal mudflats sediment characteristics and chl-a optical properties allow remote sensing of MPB primary productivity in these delicate areas. This research bridges the gap by coupling in-situ and with remote sensing data.

Ecology and conservation of small mammals

An ecological study on species composition, relative abundance and habitat association of small mammals and the impact of human interference on their abundance and diversity was carried out in Nechisar National Park during August, 2008 to April, 2009. A total of 25 species of small mammals were recorded from the study area. Out of this, 20 species were rodents of three families and five species were insectivores of two families.Among the trapped small mammals, M. natalensis and A. dembeensis were the most widely distributed, whereas O. typus, C. olivera and E. rufescens were the least widespread in distribution. The population and density of small mammals were high during the dry season and less during the wet season. M. natalensis and A. niloticus were tapped from areas near human settlements as a commensal. The diversity and abundance of small mammals were correlated with different human disturbances in the area. Grazing, fire and deforestation were intensive, affecting the diversity, abundance and distribution of small mammals in the area.

The Biology of Gelada Baboon: Theropithecus gelada

The population status and behavioural ecology of mammals have been studied mostly in protected areas. But most of mammals that live in unprotected area are not very well studied and documented. So this monograph present and inform about gelada baboon that live in unprotected area - Wonchit Valley, Ethiopia. This book covers population status, distribution, behavioural ecology and human – gelada conflict. There are more breeding females within the population of gelada baboon in the study area. The distribution of gelada baboons fluctuates during the wet and the dry seasons. A total of 60 plant species was consumed by gelada baboons during the study period. The animal consumes some species of plants in the study area that were ignored in other study areas. Gelada baboons dig the ground until the virgin land seems like the surrounding farmlands during the dry season. Human – gelada conflict in the study area is extremely severe. The only safe haven for gelada baboons is the cliff. This monograph helps for those groups who are involved in wildlife ecology and management, conservation, mammals, primates and others.

Diversity and Ecology of Parthenium weeds at Head Khanki, Pakistan

Biodiversity has traditionally emphasized on the distribution and variation of all species on earth. Biodiversity is both essential for our existence and intrinsically valuable in its own right. When species are moved to new locations that offers conditions for life similar to their native habitats, they may exploit vacant ecological niches and grow quickly, especially if they have no natural predators in their new settings. We also want to promote a sense of urgency for the need to protect wetland diversity.

Peter Morin J. Community Ecology

All life on earth occurs in natural assemblages called communities. Community ecology is the study of patterns and processes involving these collections of two or more species. Communities are typically studied using a diversity of techniques, including observations of natural history, statistical descriptions of natural patterns, laboratory and field experiments, and mathematical modelling. Community patterns arise from a complex assortment of processes including competition, predation, mutualism, indirect effects, habitat selection, which result in the most complex biological entities on earth – including iconic systems such as rain forests and coral reefs. This book introduces the reader to a balanced coverage of concepts and theories central to community ecology, using examples drawn from terrestrial, freshwater, and marine systems, and focusing on animal, plant, and microbial species. The historical development of key concepts is described using descriptions of classic studies, while examples of exciting new developments in recent studies are used to point toward future advances in our understanding of community organization. Throughout, there is an emphasis on the crucial interplay between observations, experiments, and mathematical models. This second updated edition is a valuable resource for advanced undergraduates, graduate students, and established scientists who seek a broad overview of community ecology. The book has developed from a course in community ecology that has been taught by the author since 1983. Figures and tables can be downloaded for free from www.wiley.com/go/morin/communityecology

Diversity and critical reflective work behaviour Diversity and critical reflective work behaviour Новинка

Diversity and critical reflective work behaviour

In this empirical study it was hypothesized that visible diversity and education level (diversity) are positively related to cognitive diversity and critical reflective work behaviour. But that in order to harvest the benefits of diversity, beliefs of valuing diversity are needed. Gender diversity and the average level of education within a team are found to increase the level of cognitive diversity. Analyses further revealed significant effects of task complexity and sector influences regarding critical reflective work behaviour. However, cognitive diversity did not resulted in more critical reflective work behaviour within teams. Therefore the moderating role of diversity beliefs could not be examined. The promise of diversity could not be demonstrated and more research is needed to provide more insight in the reality of diversity. Future recommendations are made and practical implications for organisations are given.

Genetic diversity and interrelationship of agronomic traits in barley

Ethiopia considered as the secondary center of genetic diversity in Barley (Hordeum vulgare L.). The high genetic diversity observed in Ethiopian barley landraces was due to its diverse environmental and soil condition. Barley landraces from Ethiopia used as a source of genes for resistant to disease and agronomic traits all over the world. International research center such as ICARDA also used Ethiopian germplasms in their breeding program to developed different cultivars well adapted to the tropical and subtropical regions of the world. In any breeding program, the study of the existing genetic diversity within their base population is a key factor for their success. Therefore, understanding the genetic architecture of the base population related to diversity and understanding the interrelationship of yield components will be crucial. It helps to design appropriate crossing program by selecting parents with divergent genetic background that meet the breeding objective. It is also important to develop core collection. So it is valuable reference for the researchers, conservation specialists, development workers, graduate and undergraduate students.

Assessment of Genetic Diversity in Asparagus spp.

Genetic diversity plays a very important role in survival and adaptability of a species because when a species’s environment changes, slight gene variations are necessary to produce changes in the organism's anatomy that enables it to adapt and survive. This book, therefore, provides an idea on molecular markers such as RAPD, ISSR and SSR technologies to detect genetic diversity of the selected medicinal plants. The advantages of molecular markers for the generation of genetic linkage maps and molecular analysis in plants have been established extensively within a short span of their inception as an efficient marker system. Their widespread use has served as a considerable genomic resource for plant breeder's providing them with an array of suitable tools for a range of target applications such as analysis of genetic diversity. Knowledge of population genetic diversity is one of the prerequisites for development of plant species conservation strategies. In the case of wild species that represent genetic resources for cultivated plants, an understanding of their genetic diversity is essential as they are the source of genetic material that are used to improve elite varieties.

Bio-Cultural Diversity in the Living City of Varanasi (Banaras), India

Documentation of various facets of biological and cultural conservation practices, with increasingly greater emphasis on societal issues, is very much essential before they are totally eclipsed by the rapid process of modernization/globalization. While examining the current literature on traditional knowledge, we notice a curious absence of scientific studies based on intensive fieldwork among a large and important section of the world rural population. In this book, an attempt has been made to link biological diversity with socio-cultural diversity in view of integrating traditional knowledge within the framework of sustainability considering sustainable development requires incorporation of ecological process with social values.

Community ecology: the study of the patterns and processes involving two or more species – has developed rapidly in the last two decades, driven by new and more sophisticated research techniques, advances in mathematical theory and modeling, and the increasing pressure on the environment wrought by humans. Once a purely descriptive science, it is now one of the most forward-looking areas of scientific inquiry. Morin skillfully guides the reader through the main tenets and central concepts of community ecology – competition, predation, food webs, indirect effects, habitat selection, diversity, and succession. In an attempt to introduce the reader to the most balanced coverage possible, Morin includes examples drawn from both the aquatic and terrestrial realm and from both plant and animal species. Balancing theory with experimentation and drawing on exciting new studies to complement the historical foundations of the discipline, he also stresses that both the empirical and theoretical approaches are necessary to drive ecology foward into the new millenium. The final chapter on applied community ecology ably demonstrates how community ecological processes have a wide environmental relevance. Although in its infancy, the application of community ecology to emerging problems in human-dominated ecosystems could mitigate problems as diverse as management strategies for important diseases transmitted by animals and the restoration and reconstruction of viable communities. Required reading for all students and practitioners interested in community phenomena, Community Ecology marks an important contribution to the development of this protean discipline. The first serious textbook for a decade on one of the keystone subdisciplines of ecology. Broad taxonomic and habitat coverage. Section on implications of community ecology for environmental issues.
