Der vorliegende Briefwechsel zwischen Alexander von Humboldt und Christian Gottfried Ehrenberg, bestehend aus ca. 300 Briefen, die Mehrzahl davon von Humboldts Hand, ist ein wichtiger Mosaikstein zum Bild der Wissenschaftsgeschichte des 19. Jahrhunderts. Ehrenberg, in seiner Zeit ein berühmter und gefeierter Mikropaläontologe, war ein geschätzter Kollege Humboldts, nicht nur in seiner Funktion als Sekretar der mathematisch-physikalischen Klasse der Königlich-Preußischen Akademie der Wissenschaften, auch als Mikrobiologe, der in damals noch kaum bekannten Bereichen forschte. Mit der vorliegenden elektronischen Edition wurde dem oft geäußerten Wunsch entsprochen, den bedeutenden Briefwechsel Alexander von Humboldts der Öffentlichkeit zugänglich zu machen. Mehrere Bände sind von der Alexander-von-Humboldt-Forschungsstelle in den vergangenen Jahren im Verlag der Akademie herausgegeben worden. Die Veröffentlichung der Korrespondenz mit dem Berliner Mikrobiologen Christian Gottfried Ehrenberg (1795 – 1876) führt weiter auf dem Forschungsfeld der noch kaum erschlossenen Kontakte Humboldts mit Biologen. ...

I have produced this site, as someone who uses statistics in my experimental work, but I am not a statistician. The site is intended to provide a simple, straightforward guide to the basics of experimental design and to some of the common statistical tests. There are several excellent sites on Statistical methods. But I think that many undergraduates (and graduate students) want only a user-friendly beginner's guide - or a refresher course - that enables them to use statistical tests with a minimum of fuss. That's the aim of this site. It is by no means a comprehensive guide, but it will get you started and, if nothing more, it will help you to understand the meaning of the symbols you see in scientific papers. You can use this site in 2 ways: If you know the statistical test that you want, then go straight to the index of tests. If you are "rusty" or a beginner, then you should read the introductory pages: The Scientific Method, Experimental design, Common statistical terms, Descriptive statistics, and what test do I need? ...

Data are one of the most valuable products of the LTER program. The LTER Network seeks to inform the LTER and broader scientific community by creating well designed and well documented databases and to provide fast, effective, and open access to LTER data via a network-wide information system designed to facilitate data exchange and integration. Currently, the LTER Data Catalog contains entries for over 6000 ecological datasets from 26 LTER Network research sites, and thousands of additional datasets from numerous other ecological field stations and research institutions. ...

The Amazon Forest Inventory Network is an international network that has been established to understand the biomass and dynamics of Amazonian forests. Since 2000 we have established a systematic framework for long-term monitoring of this region, which holds more biodiversity, water, and vegetation carbon, than any other region of the planet. RAINFOR has worked step-by-step, including partners across the nations of Amazon, taking account of the potentially strong modulating role of environmental variables like soil nutrition, and the need to help develop a new generation of Amazon ecologists. RAINFOR is curently supported by the Andes and Amazon Initiative of the Gordon and Betty Moore Foundation. ... [Information of the supplier]

iSpecies is a test of E O Wilson's idea of a web page for each species. The data displayed are generated "on the fly" by querying other data sources. iSpecies uses web services to talk to source databases, extract data, and assemble a page for each species. The code makes extensive use of XML. Essentially, each web service returns XML in one form or another, and XSL style sheets are used to transform the result into HTML. ...
