This Second Edition of Plankton is a fully updated introduction to
the biology, ecology and identification of plankton and their use
in monitoring water quality. It includes expanded, illustrated
descriptions of all major groups of freshwater, coastal and marine
phytoplankton and zooplankton and a new chapter on teaching science
using plankton. Best practice methods for plankton sampling and
monitoring programs are presented using case studies, along with
explanations of how to analyse and interpret sampling data. Healthy
waterways and oceans are essential for our increasingly urbanised
world. Yet monitoring water quality in aquatic environments is a
challenge, as it varies from hour to hour due to stormwater and
currents. Being at the base of the aquatic food web and present in
huge numbers, plankton are strongly influenced by changes in
environment and provide an indication of water quality integrated
over days and weeks. Plankton are the aquatic version of a canary
in a coal mine. They are also vital for our existence, providing
not only food for fish, seabirds, seals and sharks, but producing
oxygen, cycling nutrients, processing pollutants, and removing
carbon dioxide from our atmosphere. This new edition: contains a
new chapter on Plankton in the Classroom has greatly expanded
coverage of coastal and marine phytoplankton explains the role of
plankton in aquatic ecosystems and its usefulness as a water
quality indicator updates and details best practice in methodology
for plankton sampling and monitoring programs brings together
widely-scattered information on freshwater and coastal
phytoplankton and zooplankton and provides a list of up-to-date
references. Plankton is an invaluable reference for teachers and
students, environmental managers, ecologists, estuary and catchment
management committees, and coastal engineers.
Following a severe road traffic accident as a pillion passenger on
a motorcycle at the tender age of 13, Marc Richardson was
hospitalised for over 12 months and spent many more months
recuperating after that. During the numerous major operations he
had at such a young age, Marc had many "out of body experiences"
which he can still vividly recall. On one particular day during one
of these operations Marc was honoured and privileged to be
connected with his now inseparable spirit guide "Tommy," whom from
that day to this has guided and taught him about this world, the
afterlife and about sharing his knowledge with others.

A fiercely ecstatic tale of betrayal and self-sacrifice. Messiahs
centers on two nameless lovers, a woman of east Asian descent and a
former state prisoner, a black man who volunteered incarceration on
behalf of his falsely convicted nephew, yet was "exonerated" after
more than two years on death row. In this dystopian America, one
can assume a relative's capital sentence as an act of holy
reform-"the proxy initiative," patterned after the Passion. The
lovers begin their affair by exchanging letters, and after his
release, they withdraw to a remote cabin during a torrential
winter, haunted by their respective past tragedies. Savagely
ostracized by her family for years, the woman is asked by her
mother to take the proxy initiative for her brother-creating a
conflict she cannot bear to share with her lover. Comprised of ten
poetic paragraphs, Messiahs' rigorous style and sustained intensity
equals agony and ecstasy.
