Exploring Studbooks for Wildlife Management and Conservation

Many endangered species of wild animals are managed in captivity through studbooks. In this book these data-rich resources are mined in innovative, integrated and statistically tested ways to maximise information gain for conservation practice – whether for captive or released/reintroduced or managed wild populations. This book is thus an important tool for all species managers, and for students and researchers in small population biology and wildlife conservation.The book's studbook analyses are grouped in three interrelated sections: natural history, demography and genetics. Statistical tests to determine the significance of results or to compare results between subgroups are undertaken throughout. Real studbooks of a variety of species, e.g. cranes, wolverines, blesbok, illustrate the practical applications and interpretations of the analyses and statistics. The “natural history” section presents analyses to determine baseline species information such as litter size, inter-birth interval, longevity and seasonality. “Demography” covers census(-style) analyses, age-class based life tables, comparative survival analyses and population projections. Solutions for dealing with small sample sizes are included.Inbreeding depression and unconscious selection form the main focus of the “genetics” section. Survival and life table analyses are used to assess inbreeding effects. Quantitative genetics methods are applied to natural history traits as a tool to monitor genetic variation. A fourth section on “conservation” shows how data from captive populations can be used where natural history data from wild populations are missing. A real example uses studbook data to inform Population Viability Analysis. The final section deals with issues related to incomplete and missing data and statistical topics.The purpose-written open-source software programs “Population Management Library (PML)” and “studbookR” used for analyses in the book, are available at www.princee.com.

To achieve an effective in vivo diagnosis of prosencephalic malforma- tions it is necessary to have a systematic method that is closely corre- lated to the gross morphology of the inner and outer surfaces of the brains involved, since those are the features that are demonstrable by pneumography, angiography and computer tomography. An attempt was made to use the existing classification systems, but it then became obvious that they are poorly adapted to the requirements of modem neuroradiology. The many different forms of prosencephaly therefore needed to be re-categorized on the basis of a series of typical speci- mens. The new system is not only simpler and thus more clear-cut from the standpoint of the (in vivo) diagnosis, but in the present author's opinion it also has some advantages as regards the theoretical aspects of the problem. An essential prerequisite for its clarity is that the mal- formations belonging to theyrosepsephalysQe
