First revision of the family Metarbelidae Strand, 1909 (Lepidoptera, Cossoidea Leach, 1815) and a phylogeny based on adult morphology of 60 genera from the Afrotropical and Oriental Region
(2019-08-19)
This thesis represents the first revision of the family Metarbelidae Strand, 1909. The author's extensive research on Metarbelidae includes fieldwork made in nine lowland and montane forests of Kenya (1994–2008; 2015–2018) ......

Non-coding RNAs and Conserved Non-coding Elements in Insect Genomes
(2019-08-27)
Insects are the largest group within arthropods and in this group various phenotypes and lifestyles can be found. To understand where how this diversity evolved insects are studied on both a morphological and genomic level. ......
Ethologische Untersuchungen der Wahrnehmung von Oberflächenwellen des Wassers bei Krokodilen
(2018-03-23)
Krokodile nutzen zum Beutefang neben visuellen, auditorischen und olfaktorischen Reizen auch Oberflächenwellen des Wassers, die sie mit ihren Integumentary Sensory Organs (ISOs) wahrnehmen. ISOs befinden sich hauptsächlich ...
Complement-mediated neuronal loss by sialic acid glycocalyx alterations
(2018-04-23)
Every neuronal cell is covered with a dense structure of glycoconjugates, the glycocalyx. Sialic acids form the terminal ends of the glycocalyx and thus, are more accessible for the cellular environment. Microglia, the ...
From Perception to Cognition: Multisensory object recognition and navigation in the weakly electric fish Gnathonemus petersii
(2018-02-15)
Within a multisensory system, individual senses can interact in several beneficial ways increasing the reliability and flexibility of the multisensory percept. Such a multisensory system is found in the African weakly ......
Protein-Coding Gene Repertoires: Annotation, Characterization, and Variability in Holometabola
(2018-12-20)
Three previously unavailable prerequisites for gene repertoire analyses are established and used within this thesis: (1) a new tool (COGNATE, written in Perl) was developed and used that records all gene structure parameters ...
Animal-Robot Interactions: Electrocommunication, Sensory Ecology, and Group Dynamics in a Mormyrid Weakly Electric Fish
(2018-12-12)
Mormyrid weakly electric fish possess a specialized electrosensory system. During the process of active electrolocation, these animals perceive self-generated electric organ dis-charges (EOD) and are thereby able to detect ...
Modulation of Nrf2-mediated oxidative stress response in bovine granulosa cells and preimplantation embryos
(2019-11-13)
Nrf2 is a redox sensitive transcription factor involved in regulation of antioxidants defense mechanism against various stressors. Maintaining reactive oxygen species (ROS) within cellular homeostatic levels is crucial for ...
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 ...
Die Anpassung der Hörschwelle von einheimischen Fischarten an ihre hydroakustische Umwelt
(2014-09-15)
Verschiedene Untersuchungen haben gezeigt, dass sich die Sinnessysteme der Tiere an die Reize ihrer Umwelt anpassen. Dies sollte auch für die Fische und ihre hydroakustische Umwelt gelten. In der Arbeit wurden deshalb ...
