Population Dynamics of Aphids
ISBN: 9783639321449 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The book describe the role of aphids and their natural enemies on different varieties of cauliflower crop. Aphids are among the most destructive insect pests of cultivated crops that are widely distributed in Pakistan and throughout the world. Biological control is an essential component in integrated management of aphids. Variety selection and crop management practices are the main factors that contribute to growing profitable horticultural crops. Adjusting the planting date of row crops, thereby altering the production season, may be another viable method for reducing pesticide...

The role of acoustic communication in African Lions (Panthera leo)
ISBN: 9783639284775 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. For the evolution of social behaviour, communication has an important implication. Living in a structured social system is common in many species and involves costs, benefits and the ability to communicate with group members. Members of a group are often spatial separated and to coordinate movements and maintain social bonds between members acoustic communication is central. In this book, we tried to understand the role of acoustic communication in African lions (Panthera leo). We were interest to find out which were the features that characterized female and male lion roars and roars of...

Endocrines and Osmoregulation: A Comparative Account in Vertebrates
ISBN: 9783642076572 / Angielski / Miękka / 292 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The opportunity to prepare a second edition of a book that was originally written 30 years ago has provided me with both a challenge and a source of pleas- over ure; the former as it needed to be spatially constrained within its original limits. Nevertheless, over 1000 references have been added. I must apologize to the many biologists whose contributions could not be included. I have attempted to keep the original format and historical perspective. The information has been princi- pally described within the context of each phyletic group of the vertebrates and their habitats. Each chapter is...

Monograph of the Gonostomatidae and Kahliellidae (Ciliophora, Hypotricha)
ISBN: 9789400704541 / Angielski / Twarda / 742 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The present monograph is the fourth of six volumes which review the Hypotricha, a major group of the spirotrichs. The book is about the Gonostomatidae, the Kahliellidae, and some taxa of unknown position in the hypotrichs. Gonostomum was previously misclassified in the Oxytrichidae because its type species Gonostomum affine has basically an 18-cirri pattern, which is dominant in the oxytrichids. A new hypothesis, considering also molecular data, postulates that this 18-cirri pattern evolved in the last common ancestor of the hypotrichs and therefore it appears throughout the Hypotricha tree....

This new edition of Animal Models in Cardiovascular Research describes historical and recent advances in our understanding of the cardiovascular system from studies conducted in a variety of animal models. Since the last edition we have witnessed an explosion in the use of both congenic and transgenic animals. The use of specific knock-in and knock-out transgenic models has resulted in an avalanche of genetic, molecular and protein-based information that, potentially, could result in an amazing new array of treatment and management options. However, the results of these studies... This new edition of Animal Models in Cardiovascular Research describes historical and recent advances in our understanding of the cardiova... |

Induced resistance by growth regulators on potato against nematode
ISBN: 9783639309492 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Potato, solanum tuberosum L. is a major food crop in many countries of the world including Egypt. The production of this crop is already expanded to relatively warm and humid regions that are suitable to the survival and development of several pathogenic pests, including nematodes. Such improvement has come mainly from certain fertilizer applications, higher yielding varieties, and better methods of controlling weeds, pests and diseases such as nematodes as well as improve plant growth by certain chemical regulation i.e. growth regulators. Moreover, such growth regulators i.e. IAA...

The Edge of Evolution: Animality, Inhumanity, and Doctor Moreau
ISBN: 9780190212094 / Angielski / Twarda / 296 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this interdisciplinary work, author Ron Edwards offers an innovative rereading of H. G. Wells' "The Island of Dr. Moreau." Edwards utilizes his twenty-five years in biology and the ethics of animal research to examine the bioethical implications of Wells' work and its relevance to contemporary scientific and philosophical discussions. He tackles the myth of human exceptionalism, the notion that we are fundamentally different from the rest of the animal kingdom. We must view ourselves, he argues, not as from animals, but as animals. The approachable tone is suitable for a wide audience...
