Download or read book Unifying Concepts in Ecology written by W.H. van Dobben and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complexity of ecosystems forms perhaps the greatest challenge for natural science. Even the first step to comprehensive analysis, namely a survey of the participating species, often forms a major obstacle. This makes it understandable that ecologists try to abstract general principles from the interrelationships of the multitude of species for use in their efforts to investigate ecosystem dynamics. Such 'unifying concepts' were the main theme of the 'First International Congress of Ecology' organized in The Hague in September 1974 by the International Association of Ecology (INTECOL), under the auspices of the Division of Environmental Biology of the International Union of Biological Sciences (IUBS). This book contains the papers presented at the plenary sessions of the Congress and a summary of the discussions engendered by them. At the Congress over 800 ecologists from many countries, representing diverse disciplines such as limnology, botany, zoology, microbiology, agriculture, met together for a week. The study of ecosystem dynamics depends on mutual understanding and close cooperation, and to stimulate an integrated approach a number of main speakers were invited to contribute papers on notions such as energy flow, productivity, diversity, stability and maturity from different points of view. These invited papers were presented at the morning plenary sessions, followed by discussions.

Download or read book Fundamentals of Applied Acarology written by Manjit Singh Dhooria and published by Springer. This book was released on 2016-12-14 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acarology - the study of mites and ticks, is a subdiscipline of Zoology, and is many times considered in the field of Entomology (the study of insects). Mites and ticks are distributed throughout the world and inhabit almost every ecosystem (both terrestrial and aquatic) including grassland soils. More than 55,000 species of mites and ticks are already described. Mites and ticks directly affects humans as pests of different crops, fruit plants, vegetable crops and field crops; as parasites of human beings, veterinary animals, poultry and pets; pests of stored grains and other products; mushrooms and cheese; and as parasites of honeybees. Mite infestations are responsible for economic losses worth billions of dollars in terms of reduced crop yields and lowered quality of produce. Many species of mites serve as vectors of various plant diseases; some species of ticks cause losses through blood feeding and by transmitting many diseases among man and animals. House-dust mite allergies, and tick bite allergies are also common in many parts of the world.Present Book, "Fundamentals of Applied Acarology," is written keeping in view non-availability of any standard text dealing in different aspects of acarology at one place. Separate chapters in this book are devoted to Importance of Acarology, Historical account, acarine technology, morphology and anatomy of Acari; Feeding, Development and Reproduction. Molecular developments in relation to mites and ticks are also discussed. Role of mites and ticks in Quarantines of plants and animals; forensic/criminal investigations; and importance of accidental acarophagy are discussed in detail. Safe usage of pesticides based on their mode of action (IRAC’s Groups), development of acaricide resistance and measures to mitigate it are discussed. Mite pests of fruit trees, vegetable plants, and floricultural plants; field crops; mite problems in greenhouses/polyhouses; and mite problems encountered under organic cultivation of plants; and their management through minimum usage of pesticides are emphasized. Role of different predaceous mites in controlling plant pests like thrips, aphids and scale insects is elaborately discussed. Biological control of phytophagous mites is discussed in detail. Different animal parasitic mites and ticks are discussed from veterinary and medical point of view.At the end of each chapter, many important references for further reading; and Electronic References (ER) in the form of youtube links and other weblinks are given to understand fully how these tiny creatures look like; behave, feed and reproduce; nature of damage they cause to plants and animals; and measures to mitigate them. Weblinks will stimulate interest in the readers for more information about different mites and ticks. The knowledge contained in the book may prove as best material for "General and Applied Acarology" course for graduate and post-graduate levels, teachers and researchers in entomology, pest control advisors, professional entomologists, pesticide industry managers, policy planners, and others having interest in mites and ticks./div

Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and gen eral nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the mil ligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques fmd their way into the classroom when the problems involved have been suffici ently ironed out to permit students to master the manipulations in a few labo ratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which might be applicable for use in biology laboratory courses.

Book excerpt: Owing to man-made intervention, the shrub-steppe now represents a rapidly disappearing landscape in the arid regions of North America. This book represents a systems-level study of ecological variables affecting water balance, and responses to perturbation. The study focused on a very large, protected, landscape unit, comprising a natural ``watershed'' area located in the semi-arid western United States. Long-term and concurrent data sets were established with a view towards establishing system-level responses to manipulative interventions, and natural perturbations like wildfire. These data sets were established for micrometeorology, climatology, mineral cycling in soils, nutrient and mineral pathways in springs and streams, vegetational dynamics, and population changes on the site. In synthesizing nearly twenty years of data, the more interesting ecosystem level responses concerned vegetational recovery and water balance. For instance, the synthesis uniquely demonstrates the interaction of biotic and non-biotic factors and their integrated effect on regional water balance. However, special attention was also paid to species diversity and the genetic resource pool represented at this site.This book will be of primary interest as a reference resource to land managers and wildlife specialists, and as a research study for scientists interested in systems-level ecology. Conservation-minded citizens who take more than a cursory interest in ecology will also find it interesting.

Download or read book Biology of Earthworms written by Ayten Karaca and published by Springer Science & Business Media. This book was released on 2010-11-09 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called ‘ecosystem engineers’; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms’ innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.
