Eurasian Blackbirds (Turdus merula) and their gastrointestinal parasites: A role for parasites in life-history decisions?
(2005)
Parasites are increasingly being recognized as potent agents of selection. Gastrointestinal parasites, however, have largely been ignored. The aim of the present thesis was to contribute to the still scarce knowledge about ...
Effects of Habitat Degradation and Fragmentation on the Genetic Population Structure of Phytophagous Beetles in an African Rainforest
(2005)
In the presented study the genetic population structure of the phytophagous beetles Amphitmetus transversus (Coleoptera, Curculionidae) and Monolepta vincta (Coleoptera, Chrysomelidae) was analysed in a highly disturbed ...
The homeodomain of the Drosophila Ceramide Synthase Schlank confers nuclear import information and DNA binding capabilities
(2014-05-15)
Ceramide Synthases (CerS) are membrane bound enzymes at the center of the sphingolipid synthesis cascade. A sub-class of CerS also codes for a homeodomain of unknown function.
We previously identified the ...

Ecology and Population Status of the Puku Antelope (Kobus vardonii LIVINGSTONE, 1857) in Zambia
(2014-02-18)
Road surveys along line transects were conducted at different times during the dry season. Puku occurred in small to large groups. They preferred grassland where estimated population densities were 36.15 puku/km² in Kasanka ...
Contributions towards a better understanding of millipede phylogenetics and sawfly genomics
(2021-03-11)
A loss of biodiversity on a scale and rate comparable to the great extinction events, as a result of anthropogenic activity, has been documented for plants, animals, and micro-organisms. In order to foster a sustainable ...
Ökologie und Populationsstatus der Braunen Hyäne (Parahyaena brunnea, THUNBERG, 1820) auf Farmland in Namibia
(2022-10-13)
Anthropogene Ursachen wie der Verlust von Lebensräumen und die Ausbreitung von Menschensiedlungen sind die Gründe für den Rückgang der Populationen von Carnivoren. In der Vergangenheit wurden umzäunte und geschützte ......
Anthropogenic causes such as habit loss and the spread of human settlements are the reasons behind the decline in carnivore populations. In the past, fenced and protected wildlife areas were seen as a suitable measure to ......

Nemertean Systematics: Usefulness of DNA Barcoding and DNA Taxonomy for Species Identification, Delimitation, and Population Analyses
(2022-04-21)
The assessment of phylogenetic relationships and systematics of all metazoan taxa heavily relies on the accurate identification and delimitation of species. For the past two centuries, both species identification and ...
Reconciling Molecular with Biological and Morphological Data Towards an Integrative Analysis of the Evolutionary Biology of Chafers
(2018-03-20)
The research constituting this thesis acts at the interface of multiple disciplines related to biodiversity, combining data from morphology, genetics, geography, and ecology. Seven independent chapters (chapter II – chapter ...
Neuroanatomie und Funktionsmorphologie Peripherer Rezeptorneurone mit Direkten Projektionen in das Protocerebrum des Insektengehirns
(2023-04-20)
Zur Wahrnehmung unterschiedlicher thermischer Reize hat sich bei Insekten eine Reihe von Thermorezeptoren entwickelt. Der pyrophile („feuerliebend“) „Australische Feuerkäfer“ (Merimna atrata) besitzt paarige Infrarot-(IR)-Organe ......
Interesse an Insekten fördern: Eine Design-Based Research Studie mit Jugendlichen
(2023-02-23)
Um den Herausforderungen des Rückgangs von Insekten zu begegnen ist es von Bedeutung, das Interesse an Insekten zu fördern. Interesse ist eine wichtige Lernvoraussetzung und zentral für die Bereitschaft, Biodiversität zu ...
