Natural and artificial lateral lines: Form-function relationship and Detection of water surface waves
(2016-12-20)
The lateral line system enables fish to sense weak water motions and pressure gradients . Its smallest sensory units are neuromasts. They are composed of hundreds to thousands of mechanosensitive hair cells covered by a ...
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 ...
The role of glial calcium changes in animal models of stroke
(2015-12-04)
Ischemic stroke represents one of the leading causes of death and disability. A main characteristic of the early phase of stroke is the spontaneous appearance of peri-infarct depolarizations (PIDs), which are known to ...
Metabarcoding Invertebrate Communities in a Natural Park: From Methods to Diversity Patterns
(2021-02-22)
Biodiversity is worldwide suffering from a dramatic decline, whose underlying causes are still fairly unknown. The scientific investigation and identification of potential drivers of biodiversity loss are strongly hampered ...
Imaging a life span: In vivo Magnetic Resonance Imaging of Development and Ageing in Rat and Mouse Brain
(2016-01-28)
Rats and mice are the most abundantly used animal models in translational research. They are employed in the service of clinical research in the sense of establishing methods, testing therapeutic strategies and pharmacological ...
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 ...
Evolution of DNA methylation in insects
(2021-05-21)
DNA methylation, the addition of a methyl group (-CH3) to a genomic cytosine by a DNA methyltransferase, is the most thoroughly studied epigenetic modification across eukaryotes. Functionally, it is associated with the ...
Ultrastruktur der Kopfnieren (head kidneys) von sedentären Polychaeten und ihre Bedeutung für die Phylogenie der Annelida
(2013-04-10)
Die Phylogenie der sedentären Polychaeten ist bisher ungeklärt. Die Polychaetentaxa Terebelliformia, Arenicolidae und Capitellidae sowie die Echiura zeigen jedoch in vielen Phylognieanalysen eine nahe Verwandschaft. Innerhalb ...
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) ......
