Hardcover. Etat : New. Geography is a multidisciplinary subject, and is gaining much importance. Geography ha: become an extremely varied, versatile and high empirical discipline, and its area of study has grown a great deal since its inception. Harvey (1969) opines that geography is concerned with the description and explanation of the areal differentiation on the earth's surface Growing human population is responsible for increasing demand for resources. The available resources are scarce in nature, on the one hand, and the population is growing rapidly on the other. Hence, it is the need of the hour to adopt the optimum utilization concept for effective conservation and management of resources. Fish has become an important source of food for many centuries. Even today it is also the prime source of food substances in many coastal countries in the world. Earlier fish capturing was practiced by man with traditional methods. Today, the modern means of technology are at man's disposal. As a result, modernization has been adopted along with traditional methods. Mechanization is adopted only in marine fishing, and traditional methods are practiced not only in aquaculture but also in marine fishing activities. The high level mechanization is found in the technically advanced countries and viceversa. Fishing is one of the extractive occupations of man. It is older than agriculture. Fish provides the easiest available food for man. However, fishing is unusually difficult and does not provide lively hood for many people. It hardly absorbs less than 2 percent of the worlds labour force. Fish provides an inexhaustible source of food supply due to its incredible capacity for multiplying. Thus, marine life has to play an important role as a domestic food of man kind in future, whatever the pressure of population. This book is the net outcome of research work Ph.D. thesis submitted to Karnataka University Dharwad.…

The diversity and behavioural repertoire of invertebrates has always been inspiring for amateur naturalists and professional scientists. All over the world, this fascination for invertebrates has been encouraging studies on diverse invertebrates, helping us understand many fundamental biological processes, including ecology and evolution. Unfortunately, this is also the period of unprecedented loss of invertebrate diversity due to agrochemicals and deforestation. Globally, there is an increasing concern over the loss of invertebrate diversity. This loss of invertebrate populations across ecosystems has serious impact on ecosystem health and livelihood of dependent communities. Like many other tropical countries, very little is known about the diversity and distribution of invertebrates from India. This poor understanding of our invertebrate diversity is amply reflected in our national and regional conservation policies and goals, which is essentially formulated for large and charismatic vertebrates. This edited volume provides an overview of ongoing studies on the diversity, ecology, evolution, behaviour and conservation of invertebrates in the Western Ghats (India). …
