This work reviews and explores various aspects of uchuva growth and
development from seed germination, vegetative growth and
phyllotaxy, floral development, pollination, and pollen morphology
through fruit development, properties and health benefits. Other
sections of the book cover uchuva genetic diversity, hybridization,
chromosome number and morphological diversity. Uchuva is
economically important in most South American counties, has been
growing in popularity in Central America, and is marketed in North
American and Europe as the golden berry. This is the first concise
reference work that delves into the fascinating world of uchuva
reproductive biology. It includes the latest scientific references,
some of which have been contributed by the authors of the current
book. The authors have observed the plant in the field and have
produced a unique photographic record to help the reader see the
actual morphological structures and developmental processes in
action.
This brief reviews the pollination aspects of both wild and
domesticated fruit tree species in a global climate change context.
It explores cross-pollination mediated by insects, vertebrates and
abiotic factors, self-pollination and their global warming
implications. The authors identify the link between abiotic factors
such as precipitation and severe droughts in the context of tree
pollination and climate change. Furthermore, pollination and
conservation implications in agriculture as well as wild tree
populations are explored. Emphasis has been given to fruit trees
growing in tropical, subtropical and temperate environments.
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.
Ultra wideband (UWB) is a very promising communications technology
under active research, development, regulation, and standardization
efforts, with applications in computer and communications,
consumer, radar, automotive, and cable communications. Impulse
radio (IR) is an UWB modulation that uses waveforms that consist of
trains of time-shifted sub nanosecond pulses. Data is transmitted
using pulse position modulation at a rate of many pulses per
symbol. Multiple access capability is achieved using spread
spectrum time hopping. The IR-UWB promises to be a viable technique
to build relatively simple and low-cost, low-power transceivers
that can be used for short range, high speed multiple-access
communications over the multipath indoor wireless channel. In this
book we study the performance of IR-UWB under different scenarios.
First, we provide an overview of the research, development and
regulations efforts related to IR-UWB. Secondly, we include
examples of signal design and an assessment of the performance of
IR-UWB in the presence of noise, multipath, and multiple access
interference. Finally, we discuss some of the tradeoffs between
performance and receiver complexity.
