Excerpt from Umwelt und Innenwelt der Tiere

Mit dem Wort "Wissenschaft" wird heutzutage ein lächerlicher Fetischismus getrieben. Deshalb ist es wohl angezeigt, darauf hinzu weisen, daß die Wissenschaft nichts anderes ist als die Summe der Meinungen der heutelebenden Forscher. Soweit die Meinungen der älteren Forscher von uns aufgenommen sind, leben auch sie in der Wissenschaft weiter. Sobald eine Meinung verworfen oder vergessen wird, ist sie für die Wissenschaft tot.

Nach und nach werden alle Meinungen vergessen, verworfen oder verändert. Daher kann guy auf die Frage: "Was ist eine wissenschaftliche Wahrheit?" ohne Übertreibung antworten: "Ein Irrtum von heute."

Die Frage, ob es einen Fortschritt in der Wissenschaft gibt, ist darum nicht ganz so leicht zu beantworten wie gemeinhin angenommen wird. Wir hoffen wohl von gröberen zu feineren Irrtümern fortzuschreiten, ob wir uns aber wirklich auf dem guten Wege befinden, ist für die Biologie in hohem Grade zweifelhaft.

Die Betrachtung des Lebendigen bietet bei jedem Schritt dem unbefangenen Beobachter eine so unermeßliche Fülle von Tatsachen, daß die bloße Registrierung dieser Tatsachen jede Wissenschaft unmöglich machen würde. Erst die Meinung des Forschers, die das Beobachtete gewaltsam in Wesentliches und Unwesentliches scheidet, läßt die Wissenschaft erstehen. Die herrschende Meinung entscheidet rücksichtslos über das, was once als "wesentlich" gelten soll.

Download Data-driven Modelling of Structured Populations: A Practical by Stephen P. Ellner, Visit Amazon's Dylan Z. Childs Page, PDF

By Stephen P. Ellner, Visit Amazon's Dylan Z. Childs Page, search results, Learn about Author Central, Dylan Z. Childs, , Mark Rees

This publication is a “How To” advisor for modeling inhabitants dynamics utilizing indispensable Projection types (IPM) ranging from observational facts. it really is written via a number one study staff during this zone and contains code within the R language (in the textual content and on-line) to hold out all computations. The meant viewers are ecologists, evolutionary biologists, and mathematical biologists attracted to constructing data-driven types for animal and plant populations. IPMs could seem difficult as they contain integrals. the purpose of this booklet is to demystify IPMs, so that they turn into the version of selection for populations based by way of dimension or different consistently various features. The booklet makes use of genuine examples of accelerating complexity to teach how the life-cycle of the research organism obviously results in the correct statistical research, which leads on to the IPM itself. quite a lot of version kinds and analyses are provided, together with version building, computational tools, and the underlying idea, with the extra technical fabric in containers and Appendices. Self-contained R code which replicates all the figures and calculations in the textual content is obtainable to readers on GitHub.
