slower rates of COI gene evolution in higher plants than in animals (Kress et al. 2005). A revision of the taxonomy of the genus Daphnia (Crustacea:.

Timm Kress, Steffen Harzsch, Heinrich Dircksen, Neuroanatomy of the optic ganglia and central brain of the water flea Daphnia magna (Crustacea, Cladocera), Cell and Tissue Research, 10.1007/s00441-015-2279-4, 363, 3, (649-677), (2015). SYN-ir neuropiles in the central brain of Daphnia magna. The video shows a rotating stack of confocal micrographs depth-coded from the dorsal (red) to ventral (blue) side of the brain. Daphnia is not only a keystone organism in the food chain of many water ecosystems but also since a long time the test organism in ecotoxicology and water pollution research. These results suggest that Daphnia have to invest energy and resources to deal with protein regulation and potentially misfolded proteins under Microcystis stress, and that less energy is available for reproduction and growth. We reveal the neuroanatomy of the optic ganglia and central brain in the water flea Daphnia magna by use of classical neuroanatomical techniques such as semi-thin sectioning and neuronal backfilling, as well as immunohistochemical markers for synapsins, various neuropeptides and the neurotransmitter histamine.

Especially in Drosophila melanogaster and Daphnia species, I am studying anatomy, molecular/genomic biology Structure and development of neuronal connections in isogenic organisms: variations and similarities in the optic system of Daphnia magna. 1 Please help EMBL-EBI … 2019-04-20 endocrinology be applied to Daphnia based on its neuroanatomy and an identified neuropeptidome? Dircksen Heinrich, Kress Timm, Strauss Johannes Dept. Zoology, Stockholm University dircksen@zoologi.su.se In the water flea Daphnia pulex, we have … Selective serotonin reuptake inhibitors (SSRIs) are widely used antidepressants. As endocrine disruptive contaminants in the environment, SSRIs affect reproduction in aquatic organisms. In the water flea Daphnia magna, SSRIs increase offspring production in a food ration-dependent manner.

Though initially an enemy for Ticholla and the revitalized Z-Fighters 1. Characterization of neurotransmitter profiles in Daphnia magna juveniles exposed to environmental concentrations of antidepressants and anxiolytic and antihypertensive drugs using liquid chromatography–tandem mass spectrometry 3 Jan 2020 Background: Daphnia (Brachiopoda, Cladocera) is a well-studied model organism providing unparalleled opportunity to test epigenetic 25 Mar 2007 Oxidative and apoptotic effects of fluoxetine and its metabolite norfluoxetine in Daphnia magna · Journal & Issue Details · articleAbstract · Keywords. Mechanisms of action of selective serotonin reuptake inhibitors in Daphnia magna.

Recent studies using knockout Daphnia individuals lacking serotonin showed that these animals had the opposite phenotype as those exposed to fluoxetine: animals matured latter, reproduced less and were more mobile than wild type animals (Rivetti et al., 2018). There is thus a neurofunctional link between fluoxetine, its pharmacological target serotonin and effects (life-history and behavioural changes).

Photoperiodism is a biological seasonal timing system utilized to regulate development and reproduction in organisms. The freshwater micro-crustacean Daphnia pulex displays environmental sex determination, the precise physiological mechanisms of which are largely unknown due to the lack of an experimental system to induce female or male offspring production by alterations of the rearing endocrinology be applied to Daphnia based on its neuroanatomy and an identified neuropeptidome?

Cell and Tissue Research 363 , 649–677, https Responses of Daphnia to light are executed by less than 200 neurosecretory cells (Waterman, 1961). The optic ganglia and central brain of D. magna are recently described in detail by Kress et al. (2015). Selective serotonin reuptake inhibitors (SSRIs) are widely used antidepressants.

We reveal the neuroanatomy of the optic ganglia and central brain in the water flea Daphnia magna by use of classical neuroanatomical techniques such as semi-thin sectioning and neuronal backfilling, as well as immunohistochemical markers for synapsins, various neuropeptides and the neurotransmitter histamine. We asked whether increased serotonin levels in newly identified serotonin-neurons in the Daphnia brain mediate these effects. We provide strong evidence that exogenous SSRI fluoxetine selectively increases serotonin-immunoreactivity in identified brain neurons under limiting food conditions thereby leading to maladaptive offspring production.
