Neue statistische Verfahren zur Analyse von Monitoring- und Verbreitungsdaten von Amphibien und Reptilien

Abstract

New statistical models allow estimating the proportion of sites occupied by a species even if it is not always detected at an occupied site. These models are also useful for the analysis of monitoring data. A prerequisite for the use of this kind of models is that at least some, and possibly all, sites are visited repeatedly (at least twice). Here, I explain how these models work and discuss the underlying assumptions. As an example for illustration, I apply these models to the historic and current distribution of the adder (Vipera berus) in Switzerland.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
