Aquatic Plant Information Retrieval System (APIRS)Aquatic plant information retrieval system from the Center for Aquatic plants, University of Florida. 72,000+ citation on ecology, physiology, utilization, and control. Free to the public.
Aquatic Plant Information Retrieval System (APIRS) database now includes more than 72,000 citations, and continues to be the largest free database of its kind in the world. Beginning as a mainframe, punch-card database of a few hundred references about water hyacinths, the APIRS database now contains citation and keyword records for scientific articles and reports about uncounted species of aquatic, wetland and invasive plants. The database has been used many thousands of times by researchers, government agencies, companies, teachers, students and private groups and individuals. Users can request searches of the database or they can access the database themselves, online.
The database originally was meant to be a source of information for "aquatic weed" workers in developing countries, and was funded by the U.S. Agency for International Development for that purpose. It quickly became a source of information for workers in Florida as well, gaining the support of the then Bureau of Aquatic Plant Management of the Florida Department of Natural Resources (now the Bureau of Invasive Plant Management of the Florida Department of Environmental Protection). USAID ceased sponsorship of the database in the early 1980s.
The DEP Bureau continues to be a primary sponsor of the APIRS program. The U.S. Army Corps of Engineers Aquatic Plant Control Research Program has provided significant support in the past. The program also is supported by the St. Johns River Water Management District, with occasional special-project support coming from other agencies and companies such Cerexagri-Nisso LLC.

This new fourth edition has been completely revised and updated, covering all aspects in the field of plant sciences including biochemistry, plant physiology, cytology, ecology, genetics, evolution, biogeography, earth history, and earth sciences.Over 500 new entries, including Rosales, physical dormancy, menthol, and codeine, enhance the dictionary's coverage of botanical terms, key drugs and medicines derived from plants, and plant orders, families, and genera. It also explains many ecological terms, and expands beyond plants to describefungi and bacteria and how they affect plants.Numerous appendices include Plant Classification and SI Units, with new timelines showing important moments in plant evolution. For ease of use, vernacular plant names have been transferred to an appendix, fully cross-referenced to the A to Z entries. The dictionary's dedicated companion websitepoints to recommended web links and additional resources.The most up-to-date dictionary available on its subject, this is an essential resource for students of plant sciences and amateur botanists, as well as an entertaining and valuable guide for the plant enthusiast.
A Dictionary of Ecology, 5th edition by
This fully revised, updated, and expanded dictionary contains over 6,500 entries on all aspects of ecology and related environmental scientific disciplines such as biogeography, genetics, soil science, geomorphology, atmospheric science, and oceanography. Entries cover topics such as plant and animal physiology, animal behaviour, pollution, conservation, habitat management, population, evolution, environmental pollution, climatology, and meteorology. It also includes many line drawings and useful appendices.
Fungi: a Very Short Introduction by
The variety of the mycological world is far greater than most people imagine. Tens of thousands of fungal species have been described and many more are known only from the abundance of their genes in soil and water. Fungi are hugely important as agents of wood decay in forests, and, asparasites, they have caused the deaths of millions of people by ravaging crops and reshaping natural ecosystems.Fungi perform a variety of essential functions in ecosystems, and are important to both agriculture and biotechnology. Their importance is now becoming better appreciated among scientists, though there is much still to be understood concerning their taxonomy and evolution. ThisVery ShortIntroduction highlights the variety and extraordinary natures of fungi, revealing the remarkable facts of fungal biology and the global significance of these enchanting organisms.ABOUT THE SERIES: TheVery Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, andenthusiasm to make interesting and challenging topics highly readable.
