Pollination and Floral Ecology Book Description:

his 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. --from publisher description

Cognitive Ecology of Pollination Book Description:

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.

Putting Pollination Quality Into Analyses of Floral Ecology Book Description:

Over recent years, the extent of specialised and generalised plant-pollinator relationships, and the predictive powers of floral traits (often grouped into "pollination syndromes") as indicators of the most effective pollinators of plant species, have been questioned. Such studies, however, have used proxies such as visitation frequency rather than direct measurements of pollinator effectiveness (PE). The main objective of this thesis was to test the predictive powers of various pollination syndromes using a specific measure of PE: single-visit stigmatic pollen deposition (SVSPD). Six different classical pollination syndromes were tested, using 13 different plant species from tropical and temperate habitats, and in the case of flowers typical of the hummingbird, hoverfly, bee, oil flower and long-tongued insect syndromes, the expected pollinators were the most effective at a single-visit scale. For generalist pollination syndrome flowers, not all observed visitors were significant pollinators, and the species studied were not as broadly generalised as their visitor assemblages would suggest. In all 13 plant species, pollinator performance could appear consistent within functional visitor groups but was variable between visitor species, and in almost all cases not all of the observed visitors were effective pollinators. The pollinator performance proxies of visit duration and feeding behaviour were neither significantly, nor consistently, related to PE. Visit duration was not an accurate indicator of pollinator performance on its own, though it was useful when combined with SVSPD to define pollinator performance at a given time scale, for example per hour, per day or per season. My findings suggest that the results of recent "pollination" networks and webs, based on visitors but not necessarily pollinators, should be treated with caution. SVSPD therefore proved to be an effective and relatively simple direct measure of PE, confirming the predictive powers of pollination syndromes, and giving further insight into the extent of specialisation and generalisation.

Floral Biology Book Description:

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.

Pollination Ecology Book Description:

Researchers in plant science, zoology, and ecology will find this text to be a valuable reference. It provides a guide to the modern procedures and techniques used in the study of pollination ecology. The papers cover the recording of floral phenology, pollen histochemistry, measurement of pollination efficiency, and the investigation of breeding systems. Graphs, tables, and references supplement each chapter. Four appendices provide information on the trapping and marking of foragers, a list of reagents and solutions, a list for further reading, and suppliers of equipment.

Ecological and Evolutionary Consequences of Spatial Variation in Plant pollinator Interactions Book Description:

Solitary bee species specialized on Clarkia pollen for nest provisioning appear to be particularly important to the pollination of C. xantiana and their abundance to C. xantiana is enhanced by the presence of pollinator-sharing congeners. A three-year study of pollen limitation of plant reproduction in natural populations revealed that congeners had positive to neutral effects on bee visitation and reproductive success in C. xantiana. Attributes of populations also influenced reproductive success through their effects on the availability of compatible mates. Overall, a hierarchy of factors from the community level to the local level determined the extent to which the reproductive success of individual plants was limited by pollen.
