Abstract
Based on the notions of Mendelian population and biological species, the commonly proposed pathways of speciation are discussed with respect to the roles played by reproductive isolation as well as pre- and postzygotic incompatibility. It is emphasized that evolutionarily meaningful analyses of speciation processes require consideration of the conditions for establishment of the various mechanisms of isolation and incompatibility, which, in turn, necessitates specification of appropriate modes of inheritance of these mechanisms. Properties desirable for genetic models of speciation are derived and compared with existing models. A general result on the joint evolution of underdominance in fitness and positive assortative mating is used to evaluate the significance of hybrid disadvantage and prezygotic incompatibility on speciation. The conclusions from this evaluation are compared with observations published in an analytical review of studies on incompatibilities among Drosophila species and with the results of a genetic analysis in two lacewing species presented as evidence for sympatric speciation.

Abstract
The principle of hypothesis falsification forms the epistemological basis of systems analysis. It is realized by specification of a method of investigation suitable for testing a set of hypotheses on system characteristics. From this perspective, the principle has a special position in statistics, in that its observance calls for controlling the chances of erroneous falsification for each of the considered hypotheses. Falsification by improbability thus replaces strict falsification. Regions of rejection of hypotheses are then solely determined by the levels of significance set to the probability of not obtaining a result more probable than the observed under the respective hypothesis. Being a function of hypothesis and observation, this probability is termed the confidence zeta in a hypothesis supported by an observation, and it establishes the relation to the theory of exact testing. Taking advantage of the analogy to hypothesis testing, "exact" confidence regions can then be determined as the set of hypotheses that is supported by the observation with confidence zeta above a given level alpha of significance. The problem of hypothesis (including parameter) estimation is introduced as a problem of selecting hypotheses from confidence regions, and the roles of maximizing likelihood and confidence for obtaining and testing estimates is discussed. Maximization of confidence over subsets of hypotheses is also shown to yield unconditional tests of composite hypotheses. Application to the determination of "exact" confidence regions for the frequency parameter of the binomial distribution yielded results that are in many cases closely approximated by the direct method of Clopper and Pearson but also show distinct and unfamiliar features.

Abstract
In view of the preservation and the sustainable use of the biological multiplicity of forests as well as the assessment of the current adaptedness and adaptability of forest tree populations, a new interdisciplinary approach of focussing on adaptational history is used in order to generate system analytic hypothesis of potential effects of forest historical developments on the current genetic state of forest tree populations in Germany. On the basis of requirements for successful adaptational processes and genetic preconditions of the sustainable use of forest ecosystem resources, the analysis reveals high restrictions of adaptedness and adaptability of forest tree populations by multiple forest historic influences on the adaptational mechanisms of self-regulation and their genetic basics. Considering the example of beech (Fagus sylvatica L.), the representation of spatial distribution of genetic parameters as well as the reconstruction of descent in space enables insights on postglacial remigration routes as well as disturbances of autochthony of current tree populations caused by forest historic impacts. Recommendations, relevant to forest practice, are derived for the sustainable treatment of forest ecosystem resources in view of the climate change. For further research on sustainable use of forests as well as the distribution of genetic variation in space and time, a first step towards the modeling of forest historic impacts and the identification of autochthony of plant populations is provided. The results confirm the indispensable meaning of the explicit consideration of an interdisciplinary, retrospective research for a successful, progressive environmental research.

Abstract
Erhaltung der Anpassungsmechanismen in Baumpopulationen ist zu einem wesentlichen Anteil in der Verfügbarkeit der genetischen Informationen begründet. Diese genetischen Strukturen in Baumpopulationen können bei der Produktion von Vermehrungsgut durch die Verfahren der Beerntung, der Saatgutbehandlung und der Anzucht von Pflanzen in der Baumschule verändert werden. Die vorliegende Arbeit untersucht am Beispiel zweier Buchenbestände (Fagus sylvatica L.) die Veränderung der genetischen Strukturen (inkl. der daraus abgeleiteten Parameter) bei der Produktion von Vermehrungsgut und ihre Bedeutung für die Angepaßtheit desselben. Um den oft abstrakt verwendeten Begriff der Angepaßtheit einer Bewertung zugänglich zu machen, werden Rahmenbedingungen entwickelt, unter denen die Angepaßtheit von Vermehrungsgut meßbar ist. Anhand des Maßes der Selektionslast wird auf dieser Basis eine Zertifizierung der genetischen Eigenschaften forstlichen Saat- und Pflanzgutes vorgenommen. Mit dieser Information ausgestattet, kann der Baumschulkunde seinen ökonomischen Entscheidungsprozeß beim Erwerb von Vermehrungsgut optimieren.
