Adaptation primärer Afferenzen und Hirnstammneuronen im Seitenliniensystem des Goldfisches, Carassius auratus, auf sequenzielle Reize
Frings, Ruth Maren (2016-07-29)Weltweit sind ca. 33.000 Fischarten beschrieben, die sich in ihren Lebensraumansprüchen und in ihrer Lebensweise oft deutlich voneinander unterscheiden. Alle bisher beschriebenen Fische und aquatisch lebende Amphibien ... -
Adaptations of the four-striped field mouse (Rhabdomys pumilio, Sparman 1784) to the Namib Desert
Krug, Cornelia Bettina (2003)Animals living in arid conditions need to adapt to a number of environmental factors, namely intense solar radiation, extreme temperatures, low humidity, (dry) winds, and temporal and spatial unpredictability of both water ... -
Amyloid β-peptide-induced progressive neurodegeneration in an APP-transgenic mouse model for Alzheimer’s disease
Capetillo Gonzalez de Zarate, Estibaliz (2006)The amyloid beta-protein (Abeta) is the main component of Alzheimer's disease (AD)-related senile plaques. In the human brain Abeta-deposition occurs in a hierarchical sequence in which different areas of the brain become ... -
Analysis of the Rubbing Behaviour of Psammophiids: A Methodological Approach
de Pury, Stéphanie (2011-01-19)Several snakes belonging to the eight genera of the family Psammophiidae are the sole known snakes to smear the secretion of their nasal gland on their own belly and flanks by little rapid head movements. The main objective ... -
Analysis of veterinary pharmaceuticals in soil and their impact on microbial populations
Zielezny, Yvonne (2008)Veterinary medicines may enter agricultural soils by the use of animal excrements as fertilizers. In this study the impact of veterinary pharmaceuticals sulfadiazine (SDZ) and chlortetracycline (CTC) on soil bacterial ...

Animal-Robot Interactions: Electrocommunication, Sensory Ecology, and Group Dynamics in a Mormyrid Weakly Electric Fish
Worm, Martin (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 ... -
Die Anpassung der Hörschwelle von einheimischen Fischarten an ihre hydroakustische Umwelt
Rüter, Arne (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 ... -
Antworten einzelner Neurone im elektrosensorischen Seitenlinienlobus und im Nukleus lateralis von Gnathonemus petersii bei einfachen und komplexen elektrosensorischen Reizen
Goenechea, Lander (2002)Ziel der vorliegenden Arbeit war es, die Antwortcharakteristika von Zellen im elektrosensorischen Seitenlinienlobus (ELL, Rhombencephalon) und im Nukleus lateralis (NL, Mesencephalon) der aufsteigenden, elektrosensorischen ... -
Antwortverhalten medullärer Seitenlinienneurone von rheophilen Fischen auf kármánsche Wirbelstraßen
Kranz, Simon (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 ... -
The “Atelocerata” – A vanishing hypothesis?: Molecular phylogeny of arthropods with focus on primary wingless hexapods
Meusemann, Karen A. (2012-09-05)Arthropods encompass more than three quarters of all described living species. Among arthropods, hexapods are the most abundant group and show an enormous diversity. To understand evolutionary processes of and within ... -
Auswirkungen des Rheinhochwassers auf das Makrozoobenthos seiner Zuflüsse
Beckmann, Melanie (2002)Jeder Abschnitt eines Flussbetts ist in irgendeiner Weise „patchy“ und hat seine eigene Art von Störungen, Kolonisierungsquellen, Kolonisierern und artspezifischen Interaktionen. Aus diesem Grund befinden sich Flussbiozönosen ... -
Die Auswirkungen waldbaulicher Maßnahmen auf die Laufkäfer (Col., Carabidae) und die Wolfspinnen (Aran., Lycosidae) im Fichten- und Buchenwald (Süderbergland)
Steinweger, Andreas (2004)In Zusammenarbeit mit der Hatzfeldt-Wildenburgischen Forstverwaltung wurden in den Jahren 2000 und 2001 die Carabiden und Lycosiden verschiedener Waldbestände in Rheinland-Pfalz untersucht. Anfang der 90er Jahre stellte ... -
Bangka Archipelago and Phyllidiidae: A diversity study on marine Heterobranchia in North Sulawesi (Indonesia) with a thorough assessment of the family Phyllidiidae (Nudibranchia, Gastropoda)
Papu, Adelfia (2021-07-02)Sea slug diversity is reflecting the ecosystem and habitat diversity and also the health of these systems. Chapter 3 covers a new study location, Bangka Archipelago (BA). The substrate in BA is dominated by biogenic reefs ... -
Bee Diversity and some Aspects of their Ecological Interactions with Plants in a Successional Tropical Community
Gikungu, Mary Wanjiku (2006)This study aimed at establishing bee diversity and some aspects of their interactions with plants along a forest regeneration gradient in Kakamega Forest. To determine the bee diversity, bee samples were collected with the ... -
Biodiversity of leaf beetles (Coleoptera: Chrysomelidae) in a tropical montane rainforest ecosystem assessed with DNA barcoding
Thormann, Birthe (2016-08-09)The aim of the present study was the assessment of an unknown tropical insect fauna without traditional taxonomy. For this purpose, the diversity of leaf beetles (Coleoptera: Chrysomelidae) in the montane rainforest of the ... -
Candidate gene analysis for loci affecting sperm quality and fertility of boar
Lin, Cailu (2005)Fertility is one of the most important economical traits in swine production. Implementation of artificial insemination (AI) in swine production allowed improving selection on the boars for production traits, but at the ... -
