As issues of employee involvement and participation once more evoke considerable controversy, this textbook provides an accessible overview of the main strands, perspectives and debates in current thinking and practice. It adopts a comparative international approach, addressing developments in the United Kingdom and mainland Europe, the United States and elsewhere. The authors identify two main strands of evolution: one driven by managerial interests in enhancing and controlling employee commitment and performance; the other deriving from employees' attempts to influence high-level organizational decision-making. In particular, they examine and analyze: the background of key concepts, issues and philosophies underpinning
Deals with the entire herpetofauna of Trinidad and Tobago, covering 130 species and subspecies and their natural history. Entries on species include information on description and distribution, and contain bandw distribution maps. Includes a section of general information describing the environments of the islands, plus some 170 color photos, and identification keys. For professional and amateur herpetologists, environmentalists, and ecotourists. Annotation copyright by Book News, Inc., Portland, OR.
"Written for students at sixth form and undergraduate levels, and for 'the interested adult reader who might want to get a general feel for the subject', this is a systematic introduction to the rich diversity of Trinidad and Tobago's natural history, illustrated with maps and the author's own field photography. To manage a country's natural heritage effectively, the author argues, its organisms and ecosystems must be understood. Chronicling its degradation is not enough."--Publisher's description.
Using the historical principles of the Oxford English Dictionary, Lise Winer presents the first scholarly dictionary of this unique language. The dictionary comprises over 12,200 entries, including over 4500 for flora and fauna alone, with numerous cross-references. Entries include definitions, alternative spellings, pronunciations, etymologies, grammatical information, and illustrative citations of usage. Winer draws from a wide range of sources - newspapers, literature, scientific reports, sound recordings of songs and interviews, spoken language - to provide a wealth and depth of language, clearly situated within a historical, cultural, and social context.
In this follow-up to Islands and Snakes, this book contains 15 chapters describing diversity and conservation of snakes on islands, with foci on selected island systems not previously summarized. Attendant topics include biogeography, plasticity and evolutionary responses to insular conditions, invasive species, importance and collapse of trophic systems, threats to insular snake populations, and strategies of conservation to save them. Chapters include descriptions of snake faunas on larger islands such as Borneo and New Guinea; reproductive biology of insular snakes; phenotypic evolution; physiology and growth patterns related to diet and environment; patterns of endemism; taxonomy of snake radiations; and history of invasions by snakes on islands. The final chapter presents a discussion of prospects and overview of conservation of snakes on islands. Chapters are contributed by international authorities on respective island-and-snake systems. The latter include some islands or archipelagos that are young, or of high importance, or support snake populations that were previously not well known. The content includes colourful photographs, informative illustrations, and in some cases synthesis of new data relevant to the importance of islands for understanding the ecological underpinnings and genesis of biodiversity. Each chapter is appropriately referenced with citations to scientific literature, and where useful, footnotes, tables and graphic information supporting the narrative of the respective subject matter. The overall presentation is intended to provide readers with an enhanced appreciation for islands and the spectacular snakes that might live there.
Ticks of Trinidad and Tobago: An Overview explores tick species prevalent in Trinidad and Tobago (T&T), their distribution, associated pathogens, their effects on the host, and control methods. The book also reviews the basic biology of ticks. Ticks are known to parasitize a wide range of hosts including mammals, reptiles and birds. These parasites are of veterinary and public health significance since they are responsible for the spread of a number of pathogens to humans and animals. Worldwide, ticks are responsible for billions of dollars in losses in the livestock industry annually due to the effects of these pathogens. Based on review of the literature from more than five decades, twenty-three species of both hard and soft tick have been discovered on the twin-island republic with a greater number of species in Trinidad. Tick genera observed and recorded included Argas, Ornithodoros, Amblyomma, Dermacentor, Haemaphysalis, Ixodes, and Rhipicephalus species. The tick species found in Trinidad and Tobago parasitize both wild and domestic species. Hosts include bats, fowl, equids, wild and domestic ruminants, birds, rodents, marsupials, and a variety of reptiles such as toads, tortoises, and snakes. Based on geographical location, most tick species discovered in T&T have also been recorded in other Caribbean islands in the archipelago, North, Central and South America. Both soft and hard tick species found in T&T have also been implicated in a number of blood-borne pathogens including Borrelia, Ehrlichia, Babesia, Hepatozoon, Rickettsia, and Anaplasma. - Examines the biology of tick species on hosts endemic to Trinidad and Tobago - Provides pictorial keys - Facilitates identification, prevention, and control of tick-borne diseases in the tropical region - Assists with diagnosing tick-borne diseases
More than sixty species of snakes are found in the eastern United States, the region of highest biodiversity of all reptiles and amphibians in North America. In this brand new guide, stunning photographs, colorful geographic range maps, and comprehensive written accounts provide essential information about each species—including detailed identification characteristics, general ecology and behavior, and conservation status. Carefully researched and written by an expert herpetologist, the guide is directed toward a general audience interested in natural history. Additional information supports the already fact-filled snake species profiles. A chapter on urban and suburban snake ecology focuses on species most commonly found in some of the country’s largest cities and residential settings. A chapter on snake conservation includes information on threats faced by native species in many regions of the eastern United States. Another chapter provides the latest updates on the status of invasive species of pythons and boa constrictors that have now become naturalized permanent residents in certain areas of the country. This is the most accessible and informative guide to snakes of the eastern United States available anywhere. Covers snakes in these states (plus Washington, DC): Alabama, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, West Virginia, and Wisconsin. Features: More than 385 stunning color photographsColorful geographic range mapsSpecies accounts that cover identification, general ecology and behavior, and conservation statusExtra information on snakes in urban and suburban areasStrong conservation message, with a focus on environmental threats to native speciesCoverage of invasive snakes
