This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Plant morphology and pollination system can vary across time, and this can impact the overall reproductive success of a species. In this study, we looked at the reproductive biology of Phlox divaricata across two years and discovered that there was a difference in plant height between years, but not in floral display or flower size. The main pollinator was Lepidoptera in 2014 and Syrphidae in 2015. Preliminary results indicate Phlox divaricata cannot self-fertilize and that across all years, Phlox divaricata is not experiencing pollen limitation. Our results indicate that this prairie species has a more generalist reproductive biology that is potentially robust to changing environmental factors.

Available in PDF, EPUB and Kindle. Book excerpt: Pollination and Floral Ecology is the most comprehensive single-volume reference to all aspects of pollination biology--and the first fully up-to-date resource of its kind to appear in decades. This beautifully illustrated book describes how flowers use colors, shapes, and scents to advertise themselves; how they offer pollen and nectar as rewards; and how they share complex interactions with beetles, birds, bats, bees, and other creatures. The ecology of these interactions is covered in depth, including the timing and patterning of flowering, competition among flowering plants to attract certain visitors and deter others, and the many ways plants and animals can cheat each other. Pollination and Floral Ecology pays special attention to the prevalence of specialization and generalization in animal-flower interactions, and examines how a lack of distinction between casual visitors and true pollinators can produce misleading conclusions about flower evolution and animal-flower mutualism. This one-of-a-kind reference also gives insights into the vital pollination services that animals provide to crops and native flora, and sets these issues in the context of today's global pollination crisis. Provides the most up-to-date resource on pollination and floral ecology Describes flower advertising features and rewards, foraging and learning by flower-visiting animals, behaviors of generalist and specialist pollinators--and more Examines the ecology and evolution of animal-flower interactions, from the molecular to macroevolutionary scale Features hundreds of color and black-and-white illustrations
Download or read book Cognitive Ecology of Pollination written by Lars Chittka and published by Cambridge University Press. This book was released on 2001-05-28 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Important breakthroughs have recently been made in our understanding of the cognitive and sensory abilities of pollinators: how pollinators perceive, memorise and react to floral signals and rewards; how they work flowers, move among inflorescences and transport pollen. These new findings have obvious implications for the evolution of floral display and diversity, but most existing publications are scattered across a wide range of journals in very different research traditions. This book brings together for the first time outstanding scholars from many different fields of pollination biology, integrating the work of neuroethologists and evolutionary ecologists to present a multi-disciplinary approach. Aimed at graduates and researchers of behavioural and pollination ecology, plant evolutionary biology and neuroethology, it will also be a useful source of information for anyone interested in a modern view of cognitive and sensory ecology, pollination and floral evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Mimicry is a classic example of adaptation through natural selection. The traditional focus of mimicry research has been on defence in animals, but there is now also a highly-developed and rapidly-growing body of research on floral mimicry in plants. This has coincided with a revolution in genomic tools, making it possible to explore which genetic and developmental processes underlie the sometimes astonishing changes that give rise to floral mimicry. Being literally rooted to one spot, plants have to cajole animals into acting as couriers for their pollen. Floral mimicry encompasses a set of evolutionary strategies whereby plants imitate the food sources, oviposition sites, or mating partners of animals in order to exploit them as pollinators. This first definitive book on floral mimicry discusses the functions of visual, olfactory, and tactile signals, integrating them into a broader theory of organismal mimicry that will help guide future research in the field. It addresses the fundamental question of whether the evolutionary and ecological principles that were developed for protective mimicry in animals can also be applied to floral mimicry in plants. The book also deals with the functions of floral rewardlessness, a condition which often serves as a precursor to the evolution of mimicry in plant lineages. The authors pay particular attention to the increasing body of research on chemical cues: their molecular basis, their role in cognitive misclassification of flowers by pollinators, and their implications for plant speciation. Comprehensive in scope and conceptual in focus, Floral Mimicry is primarily aimed at senior undergraduates, graduate students, and researchers in plant science and evolutionary biology.

Book excerpt: As with nearly all living creatures, humans have always been attracted and intrigued by floral scents. Yet, while we have been manufacturing perfumes for at least 5000 years to serve a myriad of religious, sexual, and medicinal purposes, until very recently, the limitation of our olfactory faculty has greatly hindered our capacity to clearly and objectively measure scent. Today, thanks to advances in practical methodologies and affordable instrumentation, we are now able to collect, separate, and identify volatile compounds with aromatic impact. These advances are leading to much intensive investigation that has already resulted in many highly insightful and useful discoveries. Biology of Floral Scent provides the first comprehensive treatment of the biology of floral scents. It reviews the impressive research being done across several disciplines, incorporating molecular biology, enzymology, chemistry, entomology, genetic engineering, and functional genomics. Organized into a single volume for the first time, this landmark work covers every major aspect of floral scent research including- Function and significance in the interactions between plants and pollinators Composition and enzymology Evolutionary aspects Commercial applications, including the use of recently identified scent genes to genetically engineer flowers to produce new scents Meeting the needs of plant scientists, cell and molecular biologists, natural product chemists, pharmacognosists, and entomologists, as well as students in these fields, this work provides the background, findings, and insight that will stimulate new research to further advance an understanding of floral scent biology.
Download or read book Pollination and Floral Ecology written by Blake Hughes and published by Murphy & Moore Publishing. This book was released on 2021-11-16 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flowers are structures produced by angiosperms or flowering plants. Their evolutionary history has been shaped by their association with pollinators, primarily insects. The transfer of pollen grains from the stamens to the ovules, or pollination, is an essential aspect of plant reproduction. In flowering plants, the ovules are contained within the pistil, and the pollen is generally deposited on the stigma, which is the receptive surface of the pistil. In conifers and cycads, the ovules are exposed and the pollen is caught in the fluid secreted by the ovule. This process is mediated by insects, vertebrates (bats and birds), certain mammals and some lizards. Such interaction between flowers and their pollinators are mutualistic. These influence floral ecology and are believed to have led to the wide diversity of pollinators today. This book contains some path-breaking studies in pollination and floral ecology. It will also provide interesting topics for research which interested readers can take up. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of study.

Download or read book Floral Biology written by David G. Lloyd and published by Springer. This book was released on 2011-09-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Download or read book Annual Plant Reviews Flowering and its Manipulation written by Charles Ainsworth and published by Wiley-Blackwell. This book was released on 2006-05-26 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flowering plants now dominate the terrestrial ecosystems of the planet, and there are good reasons for supposing that the flower itself has been a major contributing factor to the spread of the Angiosperms. The flowers of higher plants not only contain the organs of plant reproduction but are of fundamental importance in giving rise to fruits and seeds which constitute a major component of the human diet. This volume opens with a chapter describing a model for the evolution of the Angiosperm flower. Chapters 2 to 5 describe the core development of the flower and include floral induction, floral pattering and organ initiation, floral shape and size, and inflorescence architecture. Chapters 6 to 8 focus on more specialised aspects of floral development: monoecy, cytoplasmic male sterility and flowering in perennials. Chapters 9 and 10 address more functional aspects: flower colour and scent. The book concludes, appropriately, with a chapter on flower senescence. Applied aspects are stressed wherever appropriate, and the book is directed at researchers and professionals in plant genetics, developmental and molecular biology. The volume has been designed to complement an earlier volume in our Annual Plant Reviews series, O'Neill, S. D. and Roberts, J. A. (2002) Plant Reproduction.
