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 ...
Neuroanatomie und Funktionsmorphologie Peripherer Rezeptorneurone mit Direkten Projektionen in das Protocerebrum des Insektengehirns
(2023-04-20)
Zur Wahrnehmung unterschiedlicher thermischer Reize hat sich bei Insekten eine Reihe von Thermorezeptoren entwickelt. Der pyrophile („feuerliebend“) „Australische Feuerkäfer“ (Merimna atrata) besitzt paarige Infrarot-(IR)-Organe ......
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 ...
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 ......
Home range and ecology of a palaearctic lacertid: Combining novel and old approaches to assess Lacerta agilis LINNAEUS, 1758 in the centre of its distribution with considerations for conservation
(2024-02-28)
Effective species conservation requires a thorough understanding of a species’ ecology as it reveals the requirements a species has of its environment. In this thesis I combine established methods like visual encounter ......
