Today's conservation literature emphasizes landscape ecology and population genetics without addressing the behavioral links that enable the long-term survival of populations. This book presents theoretical and practical arguments for considering behavior patterns in attempts to conserve biodiversity. It brings together prominent scientists and wildlife managers to address a number of issues, including the limits and potentials of behavioral research to conservation, the importance of behavioral variation as a component of biodiversity, and the use of animal behavior to solve conservation problems. Throughout, the text provides specific direction for research and management practices. The book is unique in its emphasis on conservation of wild populations as opposed to captive and reintroduced populations, where behavioral research has concentrated in the past.
A portrait of a species on the brinkThe only bird species that
lives exclusively in Florida, the Florida Scrub-Jay was once common
across the peninsula. But as development over the last 100 years
reduced the habitat on which the bird depends from 39 counties to
three, the species became endangered. With a writer's eye and an
explorer's spirit, Mark Walters travels the state to report on the
natural history and current predicament of Florida's flagship bird.
Tracing the millions of years of evolution and migration that led
to the development of songbirds and this unique species of jay,
Walters describes the Florida bird's long, graceful tail, its hues
that blend from one to the next, and its notoriously friendly
manner. He then focuses on the massive land-reclamation and
canal-building projects of the twentieth century that ate away at
the ancient oak scrub heartlands where the bird was abundant,
reducing its population by 90 percent. Walters also investigates
conservation efforts taking place today. On a series of field
excursions, he introduces the people who are leading the charge to
save the bird from extinction-those who gather for annual counts of
the species in fragmented and overlooked areas of scrub; those who
relocate populations of Scrub-Jays out of harm's way; those who
survey and purchase land to create wildlife refuges; and those who
advocate for the prescribed fires that keep scrub ecosystems
inhabitable for the species. A loving portrayal of a very special
bird, Florida Scrub-Jay is also a thoughtful reflection on the
ethical and emotional weight of protecting a species in an age of
catastrophe. Now is the time to act, says Walters, or we will lose
the Scrub-Jay forever.
Some ecosystem management plans established by state and federal
agencies have begun to shift their focus away from single-species
conservation to a broader goal of protecting a wide range of flora
and fauna, including species whose numbers are scarce or about
which there is little scientific understanding. To date, these
efforts have proved extremely costly and complex to implement. Are
there alternative approaches to protecting rare or little-known
species that can be more effective and less burdensome than current
efforts? "Conservation of Rare or Little-Known Species" represents
the first comprehensive scientific evaluation of approaches and
management options for protecting rare or little-known terrestrial
species. The book brings together leading ecologists, biologists,
botanists, economists, and sociologists to classify approaches,
summarize their theoretical and conceptual foundations, evaluate
their efficacy, and review how each has been used. Contributors
consider combinations of species and systems approaches for overall
effectiveness in meeting conservation and ecosystem sustainability
goals. They discuss the biological, legal, sociological, political,
administrative, and economic dimensions by which conservation
strategies can be gauged, in an effort to help managers determine
which strategy or combination of strategies is most likely to meet
their needs. Contributors also discuss practical considerations of
implementing various strategies. "Conservation of Rare or
Little-Known Species" gives land managers access to a diverse
literature and provides them with the basic information they need
to select approaches that best suit their conservation objectives
and ecological context. It is an important new work for anyone
involved with developing land management or conservation plans.
The planet is currently experiencing alarming levels of species
loss caused in large part by intensified poaching and wildlife
trafficking driven by expanding demand, for medicines, for food,
and for trophies. Affecting many more species than just the iconic
elephants, rhinos, and tigers, the rate of extinction is now as
much as 1000 times the historical average and the worst since the
dinosaurs died out 65 million years ago. In addition to causing
irretrievable biodiversity loss, wildlife trafficking also poses
serious threats to public health, potentially triggering a global
pandemic. The Extinction Market explores the causes, means, and
consequences of poaching and wildlife trafficking, with a view to
finding ways of suppressing them. Vanda Felbab-Brown travelled to
the markets of Latin America, South and South East Asia, and
eastern and southern Africa, to evaluate the effectiveness of
various tools, including bans on legal trade, law enforcement, and
interdiction; allowing legal supply from hunting or farming;
alternative livelihoods; anti- money-laundering efforts; and demand
reduction strategies. This is an urgent book offering meaningful
solutions to one of the world's most pressing crises.
A great many species are threatened by the expanding human
population. Though the public generally favors environmental
protection, conservation does not come without sacrifice and cost.
Many decision makers wonder if every species is worth the trouble.
Of what consequence would the extinction of, say, spotted owls or
snail darters be? Are some species expendable?
Given the reality of limited money for conservation efforts,
there is a compelling need for scientists to help conservation
practitioners set priorities and identify species most in need of
urgent attention. Ecology should be capable of providing guidance
that goes beyond the obvious impulse to protect economically
valuable species (salmon) or aesthetically appealing ones (snow
leopards). Although some recent books have considered the ecosystem
services provided by biodiversity as an aggregate property, this is
the first to focus on the value of particular species. It provides
the scientific approaches and analyses available for asking what we
can expect from losing (or gaining) species.
The contributors are outstanding ecologists, theoreticians, and
evolutionary biologists who gathered for a symposium honoring
Robert T. Paine, the community ecologist who experimentally
demonstrated that a single predator species can act as a keystone
species whose removal dramatically alters entire ecosystem
communities. They build on Paine's work here by exploring whether
we can identify species that play key roles in ecosystems before
they are lost forever. These are some of our finest ecologists
asking some of our hardest questions.

Documenting the species that have emerged, disappeared and been
reborn over the millennia since the Cambrian Explosion, Lost
Animals is the story of life on Earth. Over 520 million years ago,
all the major animal groups – molluscs, worms, crustaceans,
vertebrates – appear in the fossil record in what is,
geologically speaking, the blink of an eye. As well as the animals
we're familiar with today, evolution also experimented with
now-obsolete body forms. Once, the world was a blank slate, but as
this slate filled up, some lines were erased while others carried
on to this day. Beautifully illustrated with artist's
interpretations, photographs of fossils and excavations and
scientific drawings, Lost Animals brings back to life some of the
most charismatic creatures to inhabit the planet, as well as those
representing an important link or leap in evolutionary terms.
Zoologist Dr John Whitfield discusses those species we have lost,
are only just discovering and those thought extinct until
rediscovered, and the attempts to conserve and resurrect others.
The quiet manatee has long been a flash point of frequent
environmental debates. It is Florida's most famous endangered
species, as well as its most controversial. Manatees appear on
hundreds of license plates, attract hordes of tourists, and expose
the uneasy relationships between science and the law and between
freedom and responsibility like no other animal. As passions have
flared and resentments have grown, the battle over manatee
protection has evolved into a war, and no reporter has followed the
story more closely than Craig Pittman, the first environmental
writer to explore the complex history, culture, and science of the
controversies and concerns surrounding this remarkable creature.
With an abiding interest in the uncertain fate of this unique
species, Manatee Insanity provides the first in-depth history of
the attempts to provide legal protection for the manatee. Pittman
follows Florida's gentle giants through time and space, detailing
interactions with a variety of human actors, from Jacques-Yves
Cousteau to Jeb Bush to Jimmy Buffett, from a popular children's
book author to a federal lawman who dressed in a gorilla suit for
the ultimate undercover assignment.
