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 ...
Nemertean Systematics: Usefulness of DNA Barcoding and DNA Taxonomy for Species Identification, Delimitation, and Population Analyses
(2022-04-21)
The assessment of phylogenetic relationships and systematics of all metazoan taxa heavily relies on the accurate identification and delimitation of species. For the past two centuries, both species identification and ...
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 ...
Morphological evolution and phylogeny of millipedes (Diplopoda)
(2023-05-25)
Millipedes (Diplopoda) count more than 12,000 described species and play, probably since more than 400 million years, a fundamental role as detritivores in terrestrial ecosystems. Despite their great diversity and ecological ...
Interesse an Insekten fördern: Eine Design-Based Research Studie mit Jugendlichen
(2023-02-23)
Um den Herausforderungen des Rückgangs von Insekten zu begegnen ist es von Bedeutung, das Interesse an Insekten zu fördern. Interesse ist eine wichtige Lernvoraussetzung und zentral für die Bereitschaft, Biodiversität zu ...
Interaktion und neuronanatomische Grundlagen des elektrosensorischen und visuellen Systems während der multimodalen Objekterkennung: Die dynamische Gewichtung der einzelnen Sinne in Abhängigkeit ihrer Verlässlichkeit und sensorischer Vorerfahrungen beim schwach elektrischen Fisch Gnathonemus petersii
(2023-04-05)
Während der Interaktion mit der Umwelt nehmen Organismen mit den Sinnessystemen unterschiedlichste sensorische Informationen wahr. Beim Menschen wurde gezeigt, dass der multimodale Eingang während der Integration dynamisch ......
Population size estimates based on the frequency of genetically assigned parent–offspring pairs within a subsample
(2020-07-24)
Estimating population density as precise as possible is a key premise for managing wild animal species. This can be a challenging task if the species in question is elusive or, due to high quantities, hard to count. We ...
Intrasexual selection: Kin competition increases male-male territorial aggression in a monogamous cichlid fish
(2020-09-12)
During intrasexual competition, individuals of the same sex compete for access to breeding sites and mating partners, often accompanied by aggressive behavior. Kin selection theory predicts different kin-directed social ...
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 ...
Neural mechanisms involved in visual learning in the cichlid fish Pseudotropheus zebra
(2023-12-20)
Although several studies have investigated the cognitive abilities in fish, not so much is known about where the cognitive information is processed in the brain. For this PhD thesis I assessed visual learning and its neural ......
