Entwicklung eines bionischen Infrarotsensors: Evaluation von Materialparametern und Sensorkonzepten
(2015-07-07)
Der schwarze Kiefernprachtkäfer Melanophila acuminata besitzt zwei paarig angeordnete infrarotsensitive Grubenorgane mit jeweils etwa 70 miniaturisierten IRSensillen.
Jede dieser Sensillen bestehen aus einer ...

The oscillatory mechanisms of working memory maintenance
(2016-06-14)
Working memory (WM) is a cognitive process which allows for maintenance of information that is no longer perceived. Although theoretical models have recognized that working memory involves interactions across cell assemblies ...
Oxytocin – the prosocial molecule?: Intranasal oxytocin effects on social approach behavior, social cognition, volitional and emotional ambivalence in healthy human beings
(2015-10-30)
Oxytocin (OXT) is a highly conserved neuropeptide, regarding both its chemical structure and its functionality. It has been traced back at least 700 million years. OXT’s fundamental role lies in reproduction and parenting ...
Ultrastructure, Formation and Evolution of Chaetae in Annelids
(2016-02-02)
Annelid systematics has been quite unstable over the past century. Especially, with the introduction of molecular techniques to unravel phylogenetic relationships, previously established morphology-based phylogenetic trees ...
Wahrnehmung von Wirbelstraßen bei Fischen der Familien Cyprinidae und Salmonidae
(2013-01-10)
In der vorliegenden Arbeit wurden erstmals Fische aus unterschiedlichen Lebensräumen auf komplexe hydrodynamische Reize im Fließwasser konditioniert. Hierzu wurden Kármánsche Wirbelstraßen verschiedener Wirbelablösefrequenzen ...
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) ......
Erste Revision der Familie Metarbelidae Strand, 1909 (Lepidoptera, Cossoidea Leach, 1815) und die Phylogenie basierend auf der Adult-Morphologie von 60 Gattungen der Afrotropischen ......

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 ...
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 ...
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 ...
