A "New York Times "Notable Book
A stunningly original exploration of the ties that bind us to the
beautiful, ancient, astoundingly accomplished, largely unknown, and
unfathomably different species with whom we share the world.
For as long as humans have existed, insects have been our constant
companions. Yet we hardly know them, not even the ones we're
closest to: those that eat our food, share our beds, and live in
our homes. Organizing his book alphabetically, Hugh Raffles weaves
together brief vignettes, meditations, and extended essays, taking
the reader on a mesmerizing exploration of history and science,
anthropology and travel, economics, philosophy, and popular
culture. "Insectopedia "shows us how insects have triggered our
obsessions, stirred our passions, and beguiled our
imaginations.
Humans spend more time in or on the water than ever before; we love
the beach. But for many people, getting in the water provokes a
moment's hesitation. Shark attacks are big news events and although
the risk of shark attack on humans is incredibly low, the fact
remains that human lives are lost to sharks every year. Shark
Attacks explores the tension between risk and human fear and the
need to conserve sharks and protect the important ecological roles
they play in our marine environments. Marine biologist Blake
Chapman presents scientific information about shark biology,
movement patterns and feeding behaviour. She discusses the role of
fear in the way we think about sharks and the influence of the
media on public perceptions. Moving first-hand accounts describe
the deep and polarising psychological impacts of shark attacks from
a range of perspectives. This book is an education in thinking
through these emotive events and will help readers to navigate the
controversial issues around mitigating shark attacks while
conserving the sharks themselves. FeaturesClarifies what is fact
and what is fiction with regards to shark attack statistics and
explains why the fear of sharks and shark attacks is so prevalent
in modern society Discusses personal and regional mitigation
devices and measures as well as the pros and cons of each of these
Provides suggestions on how we can better manage the risk (real and
perceived) of shark attack into the future Provides a range of
personal accounts and public opinions on shark attack to round out
our understanding of these events and to provide support for gaps
in current policy
The Trinidadian guppy ("Poecilia reticulata") is well known to
biologists and home aquarium enthusiasts alike. Scientists have
studied guppies for most of the twentieth century. Some of the most
intensive recent research has been conducted by behavioral
ecologists, who have found that the guppy mating system makes
guppies especially useful in the study of sexual selection and mate
choice. By observing guppy behavior in aquaria, researchers hope to
obtain new insights into how selection operates in natural
populations. Here Anne Houde summarizes and synthesizes the
scientific work done to date, relates the empirical findings on
guppies to current themes in sexual selection theory, and suggests
new directions for future research.
This book describes the sexual behavior of guppies and examines
how mate choice by females leads to the evolution of the
conspicuous colors and the courtship displays for which guppies are
widely recognized. The author shows that female guppies prefer
males with bright color patterns, especially those with orange
spots, and that the mating preferences of females lead to sexual
selection on both color patterns and courtship displays of males.
Houde's work addresses a number of areas that are of interest in
sexual selection, including the remarkable degree of plasticity and
evolutionary lability of sexual behavior in guppies, geographic
variation in mating preferences, possible mechanisms for the
evolution of female mating preferences, and the role of sexual
selection in speciation. In conclusion, the author explores the
implications of her findings for behavioral ecologists who study
sexual selection in other species.
