This package is generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993). It comprises an interactive identification and information retrieval system using the program Intkey (running under MS-Windows), descriptions, illustrations, references, and other subsidiary material. The database contains detailed morphological, anatomical and physiological descriptions of over 800 grass genera (Watson and Dallwitz 1981; Watson, Dallwitz, and Johnston 1986; Watson 1987). The descriptive terminology employed here is mostly in line with normal agrostological usage, as set out in modern textbooks, monographs and regional floras (e.g. Hubbard 1968, Hitchcock and Chase 1950, Gould 1968, Jacques-Félix 1962, Bor 1960, Clayton and Renvoize 1986, Chapman and Peat 1992, etc.; and for anatomy, Metcalfe 1960, Clifford and Watson 1976, Ellis 1976 and 1979, and Watson and Dallwitz 1988). Detailed, written Character Notes have been entered for too few of the characters, but the copious character illustrations now provided should facilitate differentiating between character states. ...

Grasses of Iowa is an on-going project of the Ecology, Evolution, and Organismal Biology Department at Iowa State University designed to provide to a broad audience–the general public and professionals alike–a handy resource for the identification and evaluation of grasses.

Panzea is the bioinformatics arm of a project investigating the Genetic Architecture of Maize and Teosinte (NSF 0820619). The project is funded by the National Science Foundation. The project is describing the genetic architecture of complex traits in maize and teosinte. We will identify genes that control domestication traits and three key agronomic traits: flowering time, plant height, and kernel quality. We will characterize allelic series at these genes, examine their epistatic and environmental interactions, and take a step toward the ultimate goal of predicting phenotype from genotype. The genetic, germplasm, and bioinformatic resources created by this project will help maize researchers worldwide to discover the genetic basis of any trait of interest. The Panzea website provides access to the project database and bioinformatics module. The Panzea Database contains the genotypic and phenotypic data and genetic marker information produced by the project. The Panzea Database design is based on the Genomic Diversity and Phenotype Data Model (GDPDM). The database schema and an Excel file with table and field descriptions are available below. ...

The Rice Annotation Project (RAP) was conceptualized upon the completion of the rice genome sequencing in 2004 with the aim of providing the scientific community with an accurate and timely annotation of the rice genome sequence. One of the major activities of RAP is to hold jamboree-style annotation meetings on a regular basis to facilitate the manual curation of all gene structures and functions in rice. Also part of the overall objective is to facilitate a comprehensive analysis of the sequence based on the results of annotation and the construction of a public database. ...

Grasses feed the world and grasslands cover 20-40% of the planet. The grass family is one of the largest families of flowering plants with around 12,000 species. Grasses are more important for mankind than any other group of plants. Grasses have small flowering parts and complex floral morphology which is usually studied by dedicated specialists. Derek Clayton has been building a classification system for the grass family during his 56 years at Kew Gardens. He wrote the classic account Genera Graminum and went on to invent the world’s first electronic Flora and e-taxonomic system, GrassBase. GrassBase is a unique dataset of structured trait data maintained in the DELTA software system which is not supported on modern computers. Can GrassBase contribute to modern analyses and will it have use for future generations? How can grass trait data be mobilised? What are the possible connections between the study of grass diversity and other scientific disciplines? This meeting will bring together the global community of grass taxonomists to say thank you to Derek. The program will begin by exploring history and Gren Lucas, Royal Botanic Gardens, Kew, followed by Steve Renvoize, Royal Botanic Gardens, Kew, will speak about Derek’s work. Rob Soreng from the National Museum of Natural History, Washington, will describe the recent advances in grass systematics and his work on the Catalogue of New World Grasses. Elizabeth Kellogg from the Donald Danforth Plant Science Center, Missouri, will introduce Poaceae crop genomics and outline how the study of crops has helped us understand grass evolution. During the second part of the meeting we will explore the research uses of grass trait data and the significance of grass diversity for research into ecology, C4 photosynthesis, and breeding better crops. Confirmed speakers include Professor Peter Linder, University of Zurich, and Professor Colin Osborne, University of Sheffield. The meeting will conclude with presentations on descriptive taxonomic systems online and Maria Vorontsova, Royal Botanic Gardens, Kew, will lead a discussion about the future for GrassBase. ...

The Forestry Compendium is a unique global compilation of knowledge on forestry. Being a dynamic multimedia encyclopaedia, the Compendium has a comprehensive, worldwide coverage on tropical, subtropical, temperate and boreal tree species of major economic importance, and lesser-known species of local importance. It now also covers in detail many of the pests that damage these trees. It is a reference tool, which provides a basis for informed selection of woody species for a variety of uses, including for trials in plantation, agroforestry and natural forest systems. ...

Als Teil der Webpräsenz der Bayerischen Forstverwaltung bietet dieses Angebot Informationen zu einigen aktuellen waldökologischen Themen. Es werden Schadorganismen unter Aspekten des Waldschutzes behandelt; dabei wird jeweils auch ihre Biologie angesprochen. Themen sind beispielweise: Rosskastanienminiermotte (Aesculus hippocastanum, Cameraria ohridella), Eichenprozessionsspinner (Quercus spp., Thaumetopoea processionea), oder Phytophthora-Wurzelhalsfäule der Erle ("Erlensterben", Alnus glutinosa). ...

The Euroforest Portal aims to meet demands for better access to state-of-art information on European forests and forestry in an easily accessible and user-friendly form. It represents a web-based entry point into pan-European forest information in the selected topics. The portal contains a metadatabase about information in the internet and news service. Metadata is described in English, but actual URLs may contain information in any language. ... [Information of the supplier]
If all the books in the world were to be digitised, some contemporaries believe the horticultural library (Bücherei des deutschen Gartenbaus, Potsdam) would be superfluous, as all books would be on the Internet. We do not believe that it will come to that. However, various institutions worldwide have begun to digitise historial literature and make it available on the Internet. Among them is, already, a good number of horticultural books. A specific title can be easily found on the Internet. It is difficult, however, to find an overview of digitised horticultural literature. As the few horticultural books are lost in the flood of other books, we found it useful to filter them out for quick retrieval. Botanical, architectural, literary and sivicultural works are selected for inclusion. Works that are plain text and not scans are not included. ... [Information of the supplier, translated]
The Association of Forest Site Ecology and Geobotany (AFSV) has a long tradition and was boosted by the leadership of prominent forest scientists with international reputation. When established in 1928, foremost forest ecologists such as Prof. Dr. Konrad Rubner were founding members of the association. Beyond classification and syntaxonomy of forest types their geobotanical approach placed an emphasis on investigations of ecology and silvicultural application of results. After an interruption during World War II the society was re-founded in 1954. In 1985 our association was accepted as a member organization of the German Union of Forest Research Organizations (DVFFA; national agency of the IUFRO). Since 2006 the AFSV represents an independent research unit (section) within the DVFFA and is thus part of a larger national and international network. ... [Information of the supplier]
