Antwortverhalten medullärer Seitenlinienneurone von rheophilen Fischen auf kármánsche Wirbelstraßen
(2020-01-15)
Fische und Amphibien sind mithilfe der mechanosensorischen Seitenlinie in der Lage, Wasserbewegungen und Druckgradienten zu detektieren. Die Detektion dieser Reize erfolgt durch Oberflächenneuromasten auf der Haut der ...
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. ......
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 ......

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 ......

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 ......
Phylogeny and evolution of Adephaga and Neuropterida (Insecta: Holometabola) as inferred from analyses of next-generation sequencing data
(2021-09-17)
Knowing the evolutionary relationships of species is fundamental for comparative studies in biology as well as for biodiversity conservation. The main topic of this thesis is the investigation of phylogenetic relationships ...
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 ...
