Download or read book Management of Bombus Atratus Bumblebees to Pollinate Lulo Solanum Quitoense L a Native Fruit from the Andes of Colombia written by Maria Teresa Almanza Fandiño and published by Cuvillier Verlag. This book was released on 2007 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solanum quitoense (Lulo) from the northern Andes is a fruit with an attractive taste. It has a high export potential but its production is hampered by insufficient pollination. Studies on the reproductive system of Lulo revealed that, due to their poricidal anthers, the flowers need pollinators for self- and cross-pollination. Pollination by native bumblebees significantly increases fruit set and quality. Experiments show that colonies of Bombus atratus can be reared in captivity and used in Lulo fields for providing increased pollination services. Modeling based on data on colony development reveal larva/workers ratio and the supply of pollen as main parameters for improving the rearing method.

Download or read book Bee Conservation written by Lynn V. Dicks and published by Pelagic Publishing. This book was released on 2010-01-01 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together scientific evidence and experience relevant to the practical conservation of wild bees. The authors worked with an international group of bee experts and conservationists to develop a global list of interventions that could benefit wild bees. They range from protecting natural habitat to controlling disease in commercial bumblebee colonies. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bees quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bee conservation actions throughout the world. Bee Conservation is the first in a series of synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)’s Unified Classification of Direct Threats.
Download or read book Solanaceae Biology and Systematics written by William G. D'Arcy and published by Columbia University Press. This book was released on 1986 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the puzzling phenomenon of new veiling practices among lower middle class women in Cairo, Egypt. Although these women are part of a modernizing middle class, they also voluntarily adopt a traditional symbol of female subordination. How can this paradox be explained? An explanation emerges which reconceptualizes what appears to be reactionary behavior as a new style of political struggle--as accommodating protest. These women, most of them clerical workers in the large government bureaucracy, are ambivalent about working outside the home, considering it a change which brings new burdens as well as some important benefits. At the same time they realize that leaving home and family is creating an intolerable situation of the erosion of their social status and the loss of their traditional identity. The new veiling expresses women's protest against this. MacLeod argues that the symbolism of the new veiling emerges from this tense subcultural dilemma, involving elements of both resistance and acquiescence.
Download or read book Ivermectin and Abamectin written by William C. Campbell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ivermectin and abamectin, members of the avermectin family of compounds, were introduced to the market in the 1980's as a veterinary antiparasitic drug and agricultural pesticide, respectively. Their acceptance and commercial success have been remarkable; both are highly effective and in worldwide use. The efficacy of ivermectin in river blindness has expanded the interest in its use in human medicine. In response to the intense scientific and industrial interest in ivermectin and abamectin and the likelihood that they will be forerunners of an expanding family of drugs, this comprehensive monograph satisfies the need for a review and synthesis of current knowledge about the use of these substances in crop protection as well as in cattle, sheep, swine, horses, dogs, cats, birds, fish, reptiles, and in man. This overview presents chemical, biochemical, and microbiological data, as well as pharmacological, safety, and environmental aspects and covers practical use of the compounds as antiparasitic and pesticide agents, as well as the available safety data that have emerged from the clinical experience with human applications.
Download or read book Stingless Bees of Mexico written by José Javier G. Quezada-Euán and published by Springer. This book was released on 2018-08-03 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stingless bees are the most diverse group of highly social bees and are key species in our planet’s tropical and subtropical regions, where they thrive. In Mexico, the management of stingless bees dates back centuries, and they were an essential part of the culture and cosmogony of native peoples like the Maya. In recent decades a vast amount of information has been gathered on stingless bees worldwide. This book summarizes various aspects of the biology and management of stingless bees, with special emphasis on the Mexican species and the traditions behind their cultivation. Much of the information presented here was produced by the author and the team of researchers at the Universidad Autónoma de Yucatán in the course of three decades of working with these insects. Given the breadth of its coverage, the book offers an equally valuable reference guide for academics, students and beekeepers alike.
Download or read book Responses of Fruit Trees to Global Climate Change written by Fernando Ramirez and published by Springer. This book was released on 2015-01-09 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate change is expected to produce increased carbon dioxide levels in the atmosphere, higher temperatures, aberrant precipitation patterns and a host of other climatic changes that would affect all life on this planet. This review article addresses the impact of climate change on fruit trees and the response of the trees to a changing environment. The response of fruit trees to increasing carbon dioxide levels, phenological changes occurring in the trees themselves due to increased temperature and the lower chilling hours especially in the temperate regions, ecophysiological adaptations of the trees to the changing climate, impact of aberrant precipitation, etc. are reviewed. There is very little data on the impact of rising CO2 levels on fruit tree performance or productivity including the temperate region. Based on a large number of observations on the phenology, there is reason to believe that the flowering and fruiting of most species have advanced by quite a few days, but with variations in different crops and on different continents. The chilling hours have also grown shorter in many regions, causing considerable reductions in yield for several species. In the tropics, there is very little work on fruit trees; however, the available data show that precipitation is a major factor regulating their phenology and yield. The ecophysiological adaptations vary from species to species, and there is a need to develop phenological models in order to estimate the impact of climate change on plant development in different regions of the world. More research is also called for to develop adaptation strategies to circumvent the negative impacts of climate change.

Download or read book The pollination of cultivated plants A compendium for practitioners written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-10-15 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than twenty years ago, the Food and Agriculture Organization of the United Nations contributed to the growing recognition of the role of pollination in agricultural production, with the publication of “The Pollination of Cultivated Plants in the Tropics”. Since that time, the appreciation of pollinators has grown, alongside the realization that we stand to lose them. But our knowledge and understanding of crop pollination, pollinator biology, and best management practices has also expanded over this time. This volume is the second of two “compendiums for practitioners”, sharing expert knowledge on all dimensions of crop pollination in both temperate and tropical zones. The focus in this second volume is on management, study and research tools and techniques.
