Book Description
A pioneering work, Species Diversity in Ecological Communities looks at biodiversity in its broadest geographical and historical contexts. For many decades, ecologists have studied only small areas over short time spans in the belief that diversity is regulated by local ecological interactions. However, to understand fully how communities come to have the diversity they do, and to properly address urgent conservation problems, scientists must consider global patterns of species richness and the historical events that shape both regional and local communities.
The authors use new theoretical developments, analyses, and case studies to explore the large-scale mechanisms that generate and maintain diversity. Case studies of various regions and organisms consider how local and regional processes interact to determine patterns of species richness. The contributors emphasize the fact that ecological processes acting quickly on a local scale do not erase the effects of regional and historical events that occur more slowly and less frequently.
This book compels scientists to rethink the foundations of community ecology and sets the stage for further research using comparative, experimental, geographical, and historical data.
Book Description
The major objectives of a lab class, and this manual, are to provide students with hands on experiences that are relevent, easy to understand and applicable to the student's life, presented in an interesting, informative format. This lab manual has been extensively updated to provide the student with the latest information and most applicable laboratory activities possible. The manual has been expanded to provide students with more choices in activities that illustrate crucial environmental issues and relevent topics. Further, the expanded choice of labs allows each teacher to select activities that are tailored to the specific needs and circumstances of his, or her, class. Ranging from field and lab experiments to conducting social and personal assessments of the environmental impact of human activities, the manual presents something for everyone, regardless of the budget or facilities of each class. These labs are grouped by catagories that can be used in conjunction with any introductory environmental textbook. All lab activities have been field tested over the past 6 years, and are easy do within a 2 hour lab. Students, regardless of their science background, will benefit from the variety of laboratory activities offered. Relevence sections for each lab have been included to help the student see that he, or she, is doing more than "just counting trees." The instructions for each lab have been clarified and all sections shortened and updated. Finally, the students themselves have had extensive input on how to best improve the lab activities, ensuring that the voices of those most impacted by the manual are also heard.

Book Description
The study of Antarctic communities can provide a valuable step forward in investigating the control of community development, the utilization of habitats and the interaction among species in both species rich and species poor communities. This book contains chapters characterizing the present approaches to both aquatic and terrestrial communities in the Antarctic. From biodiversity to trophic flows, from ecophysiological strategies to the impacts of environmental change and the effects of human disturbance, this volume provides an up to the minute overview of community studies in an area covering ten percent of the Earth's surface.
Book Description
Ecologists, although they acknowledge the problems involved, generally conduct their research on too few species, in too small an area, over too short a period of time. In The Balance of Nature?, a work sure to stir controversy, the distinguished theoretical ecologist Stuart L. Pimm argues that ecology therefore fails in many ways to address the enormous ecological problems now facing our planet.
Ecologists describing phenomena on larger scales often use terms like "stability," "balance of nature," and "fragility," and Pimm begins by considering the various specific meanings of these terms. He addresses five kinds of ecological stability—stability in the strict sense, resilience, variability, persistence, and resistance—and shows how they provide ways of comparing natural populations and communities as well as theories about them. Each type of stability depends on characteristics of the species studied and also on the structure of the food web in which the species is embedded and the physical features of the environment.
The Balance of Nature? provides theoretical ecology with a rich array of questions—questions that also underpin pressing problems in practical conservation biology. Pimm calls for nothing less than new approaches to ecology and a new alliance between theoretical and empirical studies.

An influential work.......2001-07-18
Well, at least influential for me. Stuart Pimm's "Balance of Nature" is intended for an audience of professional ecologists and (like most academic texts) demands patient, thoughtful reading, but is well worth the effort.
Why influential? Throughout my rather lengthy graduate school "career," I've been struck by the tension between simple academic ecological theory and the stunning complexity of real-world systems. Pimm tackles this condumdrum by focusing on the relationship between species richness and system stability, explaining why the whole is greater than the sum of its parts.
If your ecological education has not already made you suspicious of popular (but naive) concepts of "natural" stability and balance, then this book will open your eyes. Recommended.
Excellent.......2000-03-11
This is an excellent book for ecologists in general

Book Description
The invasive species problem will become increasingly important in the years to come. Trade, travel and tourism are rapidly globalized, and border controls are reduced. This affects natural ecosystems in which aggressive invaders may have disastrous effects. `New' diseases affect human, animal and crop health. The Convention on Biological Diversity presents national authorities with a tall order in coping with this problem. For the first time in one volume, this book presents both ecological, biological and epidemiological aspects of invasive species, as well as the problem of disease organisms for agriculture and human health. The book constitutes a comprehensive background to the global strategy for managing invasive alien species which now is being developed by SCOPE and UNEP. The book is well suited for management staff in various environmental, economic and social sectors. It is essential for university and college teachers, researchers in ecology, natural resources management, and social sciences, as well as M.Sc. and Ph.D. students.

Description:
Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication levels and aquaculture intensity. Based on macrophyte communities associated with soft substrates, two indices of taxonomic diversity (the ''average taxonomic distinctness'' (@D^+) and the ''variation in taxonomic distinctness'' (@L^+)) were used to discriminate four of these lagoons (Thau, Salse-Leucate, Bages-Sigean and Mauguio). Bages-Sigean presented a significant higher average taxonomic distinctness (p
<0.05) and Salse-Leucate had a significant higher variation in taxonomic distinctness (p
<0.05) without considering exotic species. The index values were neither influenced by sample size nor by presence of exotic species. Thus, the ''average taxonomic distinctness'' was related to human activities and eutrophication level whereas the ''variation in taxonomic distinctness'' was more related the environmental variability, associated with the prime stressor of salinity in brackish coastal lagoons.

Description:
The present paper describes basic ecological distributions in a community of beech forest Hymenoptera. It shows that the species diversity-body weight and the density-body weight distributions give rise to a new distribution that relates total community biomass to species diversity. For Hymenoptera this distribution follows a power function with a slope of 1.3. Combining this relation with the species-area and the individuals-area relations resulted in two other distributions that relate community biomass to area and individual numbers. It appeared that population densities decrease when computed over larger areas. The biomass-species diversity relation offers a new and simple way to estimate total community biomass from samples. The possible implications of this distribution to the productivity-diversity debate are discussed.

Description:
Relationships between plant diversity (H diversity index) and above-ground biomass (as a surrogate of productivity) were analysed using quadrat data and biomass measures from a precipitation gradient in length of ca. 1000km in temperate grasslands, south-eastern Mongolia. These analyses were performed both at different ecological scales including taxonomic or functional levels, such as species, community and ecosystem, and at different geographic scales, such as local, landscape and region. Results showed that diversity-productivity relationships differ with different observed ecological and geographical scales in the temperate grasslands of south-eastern Mongolia. In detail, at the individual species level, all relationships between plant diversity and above-ground biomass from local scale to landscape and regional scales are positive and non-linear. At the community level, such relationships are mostly unimodal from landscape to regional scales. At the ecosystem level, the relationship is unimodal at regional scale. A general trend of diversity-productivity relationships in this region seems to be from positive non-linear to unimodal patterns if the scales change from low to high ecological levels and from small to large geographical scales. The unimodal pattern is common in this region.

Don't drink the water. Don't swim in it, fish in it, or even bathe in it. Rodney Barker's book, And the Waters Turned to Blood details the latest plague to visit our shores: Pfiesteria piscicida, the "cell from hell," an aquatic microorganism that causes sufferers to exhibit symptoms similar to Alzheimers or multiple sclerosis. As it follows the fortunes of Dr. JoAnn Burkholder, one of the first scientists to recognize the danger of Pfiesteria, Barker's book reads like a cross between science fiction and conspiracy theory: Dr. Burkholder discovers that excessive pollution in the rivers and coastal waters of the Southeastern United States causes a deadly microorganism to breed like crazy; state and federal government attempts to suppress the report.
An investigative reporter by training, Mr. Barker writes And the Waters Turned to Blood like a thriller, revealing pieces of the puzzle judiciously as he builds tension. Unlike in a literary thriller, however, there is no tidy ending to this story. Readers will be left with the disturbing knowledge that fish are still dying, fishermen are still getting sick, and the potential for disaster in this latest scourge is still unmeasured.

Review of Mr. Rush's AP Environmental Science Class.......2007-01-02
This dramatic account of this toxic dinoflaggellate is factual and descriptive. The beginning is well-paced and keeps the reader's attention. However, toward the middle of the book the plot becomes repetitive and more politically based. It was frustrating for the reader to read all the processes of funding and the failures. The book informs the public of a topic that is kept secret by the government. The author researched the data well and presented the information in an interesting way including a cliff-hanger to end each chapter. Overall, this book is recommended for an interesting read into the danger that lurks the coastal waters of North Carolina.
Are you reading This??? im only 11 why does it matter what i think.......2006-02-28
This book was overall a good read, but the widespread exaggeration of the effects of the dinoflagellate became quite repetitive. I was impressed that the book was able to tie politics and environmental policies together. At times, the plot was mildly interesting when compared to other environmental books. The government policies, though, became very confusing at times and the romantic aspect of Dr. Joanne Burkholder's life was not sufficiently explained.
"And the Waters Turned Mediocre...".......2006-02-28
The sheer mediocrity of this novel is stunning. It seems to be split into two main parts. The first half of the book is about the actual investigating of the organism and is quite compelling. However, the second half of the book is about a poorly covered up conspiracy theory and is very repetetive. This is dry and is pretty boring. Therefore, the two halves balance each other out to make the novel mediocre. This book is very good, though, in showing the life and career of a scientist, so would be great for an aspiring scientist. It also reveals the state of the waters in North Carolina, a concern to any of the state's citizens.
Awesome Book for the Lay Scientist!.......2005-12-16
Picked this book up while at the pubic library with my family. The except about an "ancient life form" peaked my interest and I had to borrow it. It reads like a very practical novel with a roller coaster ride of excitement about Dr. Burkholder's discovery of this toxic ameoba. I was truly fascinated and couldn't put the book down. The science is broken down so that a lay person can grasp it and understand the importance of JoAnn's findings. Her trials and tribulations with back stabbing colleagues, NC bureacrats, and the dinoflagelate itelf are very interesting. Would highly recommend this book to anyone.
A True Life Horror Story!.......2005-10-10
I live in North Carolina and this is very scary. People are not being told about this very real danger that can do real damage to a persons health just from going in the water.
The fact that I still haven't heard anything about this in the news just makes it worse.
This is scary but the fact that our goverment keeps this type of information from us is even worse.
When you come to N.C., remember there is a monster in the water and it is as bad or worse then the shark in Jaws. Maybe it's time for the movie version. At least an update on the subject.

Book Description
Blooms of toxic or harmful microalgae, commonly called "red tides", represent a significant and expanding threat to human health and fisheries resources throughout the world. The impacts of these "harmful algal blooms" range from illness and death of human consumers of shellfish or fish that have accumulated algal toxins to ecosystem alteration and mortalities of marine mammals and other animals.
Presented here is a state-of-the art review of all major topics relating to the ecology and physiology of harmful algal bloom species. The autecology of all major groups is covered in detail, and the ecophysiological processes and mechanisms that regulate their growth, bloom development, and toxin production are addressed as well.

Introduction to the world of dinoflagellates.......2001-04-19
Dinoflagellates are with few exceptions unicellular organisms found in marine and freshwater environments, and this book describes all major parts of the biology and ecology of dinoflagellates in both environments. Each chapter are written by some of the best people within the different fields that the book deal with, and there is an extensive review of literature about dinoflagellates. So in short this an extensive introduction to the vast field of dinoflagellate biology and a great reference book for dinoflagellate literature.
