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 ...
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 ...
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 ...
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) ......

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 ...
Electric Imaging in Weakly Electric Fish and Biomimetic Devices
(2022-08-03)
The nocturnal and weakly electric fish Gnathonemus petersii inspects its murky habitats by self-generated electric signals; an adaption called active electrolocation, enabled by the fish's active electric sense. Animals, ......
Electric Imaging – Aktive Elektroortung in schwach elektrischen Fischen und bionischen Sensoren
Der nachtaktive und schwach elektrische Fisch Gnathonemus petersii besitzt einen aktiven elektrischen ......

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 ......
