Book Description
In Macroecology, James H. Brown proposes a radical new research agenda designed to broaden the scope of ecology to encompass vast geographical areas and very long time spans.
While much ecological research is narrowly focused and experimental, providing detailed information that cannot be used to generalize from one ecological community or time period to another, macroecology draws on data from many disciplines to create a less detailed but much broader picture with greater potential for generalization. Integrating data from ecology, systematics, evolutionary biology, paleobiology, and biogeography to investigate problems that could only be addressed on a much smaller scale by traditional approaches, macroecology provides a richer, more complete understanding of how patterns of life have moved across the earth over time. Brown also demonstrates the advantages of macroecology for conservation, showing how it allows scientists to look beyond endangered species and ecological communities to consider the long history and large geographic scale of human impacts.
An important reassessment of the direction of ecology by one of the most influential thinkers in the field, this work will shape future research in ecology and other disciplines.
"This approach may well mark a major new turn in the road in the history of ecology, and I find it extremely exciting. The scope of Macroecology is tremendous and the book makes use of its author's exceptionally broad experience and knowledge. An excellent and important book."—Lawrence R. Heaney, Center for Environmental and Evolutionary Biology, the Field Museum
Book Description
Major researchers in the field present overviews of current thinking about the form and determinants of macroecological patterns. Each section presents different viewpoints on the answer to a key question in macroecology: Why are most species rare and small-bodied, and restricted in their distribution?

Book Description
Macroecology is the study of large-scale community structure and the influence this has on small-scale process. In recent years there has been a definite trend towards the large-scale approach, and this work is therefore timely and relevant. As John Lawton observes in a recent journal article, To discover general patterns, laws and rules in nature, ecology may need to pay less attention to the 'middle ground' of community ecology, relying less on reductionism and experimental manipulation, but increasing research efforts into macroecology. (Oikos, 1999)The book is probably too advanced for the undergraduate student, and so the core market will lie with graduate and professional ecologists.

Description:
There is an urgent need to discover global ecological principles. Similarly, known ecological rules should be checked for generality across biogeographical and climatic regions. Summarizing a large number of ecological papers can successfully reveal this macroecological information. Nowadays, however, ecological journals do not provide much suitable data for such generalizations. In a literature meta-study about the relationship between plant diversity and soil acidity, 22 papers from the Journal of Ecology were used, besides papers from other journals. Here I analyzed the dates and geographical coverage of these papers. Most of papers with usable data were from 1960s and 1970s, although the popularity of soil pH-plant diversity topic has generally increased in time. In the more recent studies the actual data were rarely available. Papers from exotic regions peaked in 1970 and from 1988 there were no articles from outside Europe or North America. This is indicating a shift in publishing tradition in ecology. Nowadays small-scale works from well-studied regions predominate and very little broader descriptive data have been provided in regular ecological papers. This will make it difficult to perform good global generalizations in the future. We can, however, have more ecological data for large-scale generalizations if more background data are put in Electronic Archives or Supplementary Appendixes on the Internet. I strongly suggest it for most regular ecological papers.

Description:
Although our understanding of environmental risk assessment in temporary wetlands has been improved by the use of multi-species toxicity testing, we still know little of how landscape variables mediate the strength of, and recovery from, anthropogenic stress in such ecosystems. To bridge this research gap, we provide a theoretical framework of the response of temporary wetlands to anthropogenic disturbance along a habitat-isolation continuum based on island biogeography theory, landscape ecology and dispersal and colonization strategies of temporary wetland organisms.

Description:
Macroecology deals with variation and covariation of complex variables, such as body size, population density and geographic range size (GRS), measured across species at broad spatial scales. Despite the increasing number of papers in this field, little attention has been given to the links between patterns at different scales. In this paper, we analysed the constraint envelope formed by the macroecological relationship between GRS and body size for 70 species of New World terrestrial Carnivora. The lower-right constraint line of this envelope is usually interpreted as the minimum viable GRS that keeps extinction risks relatively low across evolutionary time, and in this paper we fitted this line by multiplying average home range size (established by allometric equations) by different minimum viable population sizes, establishing a minimum viable GRS. Then we estimated the difference between actual geographical range size and minimum viable geographical range size, in log scale (@DA), which indicates how large is the geographic range of a species in relation to the minimum necessary to its long-term persistence. These @DA values are significantly correlated with extinction risk defined by IUCN threat categories, even after keeping geographical range size constant and after taking into account phylogenetic structure in data. This gives support to the minimum viable population model explaining the relationship between GRS and body size and highlights a way to use constraint envelopes to evaluate the influence of complex variables to predict extinction risks.

Description:
Recent studies of geographic patterns of nonindigenous species richness suggest that a few key biogeographic and anthropogenic factors explain much of the variation in the richness of established species. It remains unknown, however, if the factors identified in these studies are taxon- and scale-specific or if general rules apply broadly across taxa and spatial scales. To address this issue, I used multiple regression analysis to identify factors that contribute significantly to variation in nonindigenous herpetofaunal richness at a relatively small spatial scale, the county level, in Florida, USA. Additionally, I used the Jaccard similarity index to determine if nonindigenous species affect the biotic similarity of the herpetofaunas of Floridian counties. In the regression analysis, county latitude strongly and negatively affected nonindigenous herpetofaunal richness, explaining approximately two-thirds of the variation in this variable. To a smaller degree, human population and university presence both related positively with nonindigenous herpetofaunal richness. Several other variables, including county land area, were not significantly related to nonindigenous herpetofaunal richness. The consistent importance of human population to nonindigenous species richness in this and past studies suggests that the influence of anthropogenic factors may be universal and are as or more important than the natural biogeographic factors that generally relate with native species richness. No evidence of overall homogenization was found based on Jaccard index values. However, a significant relationship between homogenization scores and distance between counties suggests that the effect of nonindigenous herpetofaunal richness on the similarity of county biotas is scale-dependent, such that adjacent counties tend to experience homogenization, while distant counties tend to experience differentiation as a result of the presence of nonindigenous herpetofauna. The results of this and similar studies may be useful in predicting the introduction and spread of nonindigenous species and in evaluating the effects of such introductions on native biodiversity.

Description:
Species numbers are increasing rapidly. This is due mostly to taxonomic inflation, where known subspecies are raised to species as a result in a change in species concept, rather than to new discoveries. Yet macroecologists and conservation biologists depend heavily on species lists, treating them as accurate and stable measures of biodiversity. Deciding on a standardized, universal species list might ameliorate the mismatch between taxonomy and the uses to which it is put. However, taxonomic uncertainty is ultimately due to the evolutionary nature of species, and is unlikely to be solved completely by standardization. For the moment, at least, users must acknowledge the limitations of taxonomic species and avoid unrealistic expectations of species lists.

Book Description
Veterinary Parasitology Reference Manual, Fifth Edition provides easy access to pertinent information on parasite life cycles, importance, location in host, zoonotic potential, current literature, diagnosis, and treatment. Chapters are organized by animal host species, including laboratory animals, humans, llamas, ratites, dogs, cats, ruminants, horses, pigs, and birds, as well as reptiles, wildlife, and marine animals, often missing from veterinary parasitology textbooks, but of practical interest to veterinarians.The manual includes step-by-step instructions for the most common diagnostic procedures used in routine veterinary practice.Features of the Fifth Edition include:Updated and enhanced referencesInformation on new drugsImproved parasites of marine mammals sectionSections on laboratory animal parasites and human parasitesOver 500 photographs and figuresForeyt underscores the strong relationship between parasites and the overall health of animals and stresses that indiscriminate use of drugs is a poor substitute for good management and nutrition in controlling parasites. The text also offers insights into the evolving relationships between hosts and parasites.Wildlife and zoo workers, veterinary practitioners, students, and technicians will find this to be a readable and accurate resource of information about parasites in a variety of animals -wild, domestic, common and exotic.
Customer Reviews:
Excellent Reference.......2006-11-04
This literature is an excellent photographic reference of microscopic parasites. A failing is photos lack color.
Veterinary Parasitology: Refrence manual.......2006-03-23
This book is great, I use it for parasitology class every week. It has great identification pictures. I would highly recommend this book to anyone, especially vet techs.
For veterinarians and veterinary pathologists.......2006-03-16
Great book, covering much animal species with their specific parasites. Nice pictures.
Good but..........2005-12-28
This book is very helpful for fecal identification of most parasites. It does not help you with identification of larvae or adults. The book is also not in color which can be a factor when identifying the differences between some eggs. It also can have more than the necessary information (llamas, pigs, wildlife, humans). Overall a good reference to have on hand.
Foreyt.......2005-08-31
Very handy reference manual for egg identification, but would be even better if it contained pictures of larvae and adults.
Book Description
For veterinarians and veterinary technicians involved in the diagnosis of parasitism in animals, this book has become essential reading. As with the 6th edition, the 7th edition of Veterinary Clinical Parasitology has been prepared under the auspices of the American Association of Veterinary Parasitologists (AAVP) and focuses on morphologic identification of parasites of domestic animals. The various techniques described provide an accurate and cost-effective means of diagnosing parasitic infections in animals. The 7th edition has been expanded significantly to include additional globally important parasites. Extra text material has been added for each parasite to indicate its distribution, life cycle, and importance, and the illustrations are now in color to aid diagnosis. "... enthusiastically recommended to veterinarians, veterinary students, and animal health technicians." JAVMA "... useful to practitioners and clinicians in carrying out routine and established parasitological examinations in their clinics and hospitals." Canadian Veterinary Journal
Customer Reviews:
Still the best!.......2007-09-15
Miss Reith is referring to the 6th edition not the 5th. The 5th edition is still the premier reference for any parasitology student. Unfortunately the 6th edition and later editions were edited, diluted and reformatted to become a nice fecal collector used to house train a pet. Useless is a kinder description. Find, buy any edition before the 6th!
Still an essential book for the practitioner.......2001-04-11
I was surprised at Dr.? Reith's review of this book. Contrary to what Reith affirms, the book IS divided into host sections, al least for the parasites diagnosed by fecal examination; actually, there are 28 pages and 55 photographs devoted to dogs and cats, 16 pages and 32 photographs devoted to ruminants, etc. Parasites of the urinary tract, genital tracts, or skin are in a separate chapter, as are blood parasites and arthropods. This does not bother me terribly. I wish Reith had mentioned the "very common parasites" that are not included; I have not missed any yet of the common ones in a veterinary practice. I have a fairly extensive collection of parasitology diagnosis books and, for the variety and/or quality of the photos, this is still the best. I only wish that some of the photos were in color but I am not sure I could afford it. I still recommend it very strongly to my students of Veterinary Parasitology and to veterinary practitioners.
Not nearly as useful for reference as the previous edition........1999-07-24
The features that made the 5th edition so helpful as a reference, like separating the book into sections according to the type of host (ie: dog, sheep, horse, rodent), and showing photos of the parasites that commonly are found in or on that host, have been removed. Additionally, some very common parasites are not even included in this 6th edition! Rather than a good reference book, it has now been reduced to somewhat of a primer on parasitology, one that introduces you to 'types' of parasites, rather than one that actually enables you to recognize characteristics of one parasite that distinguish it from another, similar parasite so that you can specifically identify it. This book is no longer useful, as the previous edition was, for reference work. I do not recommend it.
Book Description
Cowan and Steelâs Manual has for many years had an essential role in every laboratory of microbiology and bacteriology. This substantially revised new edition, which is modelled on the successful pattern established in the previous two editions, has been fully updated and is suitable for all bacteriological laboratories using traditional diagnostic methods. It is essentially a practical manual with up-to-date contributions and key references by experts to the diagnostic characteristics of the bacteria likely to be encountered in public health and hospital microbiology laboratories, as well as in medical and veterinary practice. This edition contains new sections on rapid and mechanised test methods, and on the laboratory applications of computer theory and practice to the identification of bacteria. As in previous editions, the importance of laboratory quality control and proficiency procedures are emphasised. The Appendices give details of the laboratory methods and media for all the recommended diagnostic tests and, in addition, provide abstracts of the official guidelines for bacterial nomenclature.
Customer Reviews:
Good!.......1997-06-19
My lab wouldn't exist without this book!
The flow diagrams make ID a breeze and they even include recipes for the media and reagents.
There are a couple of typos (+ that should be - for instance), and it does need up-dating (cmon editors!) but I'd warmly recommend this to any diagnostic Micro lab that isn't fully automated

Fish Disease: Diagnosis and Treatment
ASIN: 0851997384 |
Book Description
The knowledge of isolation and identification of bacteria from aquatic animals and the aquatic environment is expanding at a rapid rate. New organisms, be they pathogens, environmental, normal flora, or potential probiotics, are being described and reported each month. This has resulted due to increases in aquaculture research, in intensive fish farming systems, and in the international trade of live aquatic animals and products as well as the emergence of new diseases. This manual provides a source that enables the identification of bacteria that may be found in animals (particularly fish) that inhabit the aquatic environment. The emphasis is on bacteria from farmed aquatic animals.
