Efecto de La Marea En El USO de Diferentes Zonas Por Las Aves Playeras
ISBN: 9783659026492 / Hiszpański / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Mexico es un pais clave en la ruta migratoria de las aves playeras. Los humedales de Guerrero Negro (naturales y artificiales) sobresalen por su abundancia. La utilizacion de estos ambientes por las aves playeras puede estar relacionada con los niveles de marea. Para determinar dicha relacion, entre agosto-2005 y marzo-2006, se realizaron censos mensuales en diferentes niveles de marea, identificando y cuantificando los individuos presentes en un sitio natural y uno artificial. Adicionalmente para las especies mas numerosas se determino el porcentaje de individuos alimentandose. Las especies...

Bioecology of the invasive fruitfly Bactrocera invadens
ISBN: 9783659131660 / Angielski / Miękka / 208 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work established the temperature range for development and survival of Bactrocera invadens, an alien invasive fruit fly species of Asian origin. The optimal temperature for survival was found to be 25 C while 35 C was the most lethal temperature. The insect infested fourteen plant species particularly mango and citrus and the wild plants marula plum and tropical almond. In host preference studies, mango and banana were found to be the most preferred host plants. The spatial and temporal population dynamics revealed that the relative abundance index (RAI) of mango pests was in the order...

Phthalate-induced reproductive toxicity in male rat
ISBN: 9783659173479 / Angielski / Miękka / 208 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In recent years, there is an increasing concern that occupational and environmental exposure to toxic pollutants disrupts male reproduction of wild life and humans. Phthalates are a family of industrial chemicals produced from alcohols that have been used for a variety of purposes, such as plasticizers that impart flexibility and durability to polyvinyl chloride (PVC) products. When incorporated into PVC, phthalates are not covalently bound and are therefore easily released into the environment, consequently resulting in animal and human exposure. Besides, phthalates have also been used...

Status of colonial waterbirds of Vaduvoor Lake, Tamil Nadu, India
ISBN: 9783848446353 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Wetlands have been threatened by urban, industrial, and agricultural expansions, which have jeopardized the integrity of this unique ecosystem. As a result, avifauna that exploits the wetlands has severely been affected. The Vaduvoor Lake in Tamil Nadu, India is one such wetland that supports large number of migratory and resident birds. Indian Bird Conservation Network has recently identified this lake as one of the Important Bird Areas (IBA) of India, despite which no attempt has been made so far to study this wetland or the avifaunal species dependent on it. The present study focus...

Radiolaria
ISBN: 9781461255383 / Angielski / Miękka / 355 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The study of marine plankton has traditionally focused on those or ganisms that appeared to have obvious ecological significance in un derstanding the major patterns of biological productivity, trophic relations, community structure, and the dynamic interaction of living things with the physical environment. Not infrequently, this thrust has centered on the apparently most abundant and/or larger members of the plankton community, including significant primary producers such as the diatoms, nonthecate algae, and flagellates, or the major con sumers--copepods, gelatinous metazoa, and other...

Vertebrates in Complex Tropical Systems
ISBN: 9781461281337 / Angielski / Miękka / 200 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book addresses the question of what determines species richness in tropical animals by comparing and contrasting the communities of the five major classes of vertebrates in two environments considered to be the most species-rich on Planet Earth - the coral reef and the rainforest. All the contributors were asked to examine how so many species could coexist in such communities and to discuss the ways species assemblages might have evolved over time. Because the coauthors are ecologists, emphasis is quite naturally placed on the first of these two questions, and the factors contributing to...

Auditory Computation
ISBN: 9781461284871 / Angielski / Miękka / 518 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The auditory system presents many features of a complex computational environment, as well as providing numerous opportunities for computational analysis. This volume represents an overview of computational approaches to understanding auditory system function. The chapters share the common perspective that complex information processing must be understood at multiple levels; that disciplines such as neurobiology, psychophysics, and computer science make vital contributions; and that the end product of computational analysis should be the development of formal models.

Living Fossils
ISBN: 9781461382737 / Angielski / Miękka / 291 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The case history approach has an impressive record of success in a variety of disciplines. Collections of case histories, casebooks, are now widely used in all sorts of specialties other than in their familiar appli cation to law and medicine. The case method had its formal beginning at Harvard in 1871 when Christopher Lagdell developed it as a means of teaching. It was so successful in teaching law that it was soon adopted in medical education, and the collection of cases provided the raw material for research on various diseases. Subsequently, the case history approach spread to such varied...

Spontaneous Alternation Behavior
ISBN: 9781461388814 / Angielski / Miękka / 211 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A wide variety of species, including human beings, exhibits a remarkably reliable behavior pattern, known as spontaneous alternation behavior (SAB), that has intrigued researchers for over seven decades. Though the details may vary depending on species and setting, SAB essentially entails first choosing one member of a pair of alternatives and then the other, without instructions or incen tives to do so. Spontaneous alternation is manifested even in the early trials of a discrimination-learning experiment, where only one of the choices is reinforced. Indeed, that was the setting in which SAB...

Vaccines have historically been considered to be the most cost-effective method for preventing communicable diseases. It was a vaccine that enabled global eradication of the dreaded disease smallpox. Mass immunization of children forms the anchor of the strategy of the World Health Organization (WHO) to attain "health for all" status by the year 2000. Vaccinology is undergoing a dimensional change with the advances that have taken place in immunology and genetic engineering. Vaccines that confer short or inadequate immunity or that have side effects are being replaced by better vaccines. New...
