The stocks of the European eel Anguilla anguilla are in decline and there is an increasing awareness that poor health status due to contaminants and/or diseases might be a key element in this decline and might be a hindrance to recovery. Many countries have started compiling data on the health status of eels in their water bodies. Objectives for these monitoring actions are diverse and there is...
This paper describes work done on creating the logic programming language Eel. Eel is an is an extension of prolog which reserves two predicates to handle i/o, process communication and process initiation. The paper also presents an adaption of a behaviour based agent architecture and gives examples of how parts of that adapted architecture can be implemented in Eel. As an aside the paper comme...
The Japanese eel is a much appreciated research object and very important for Asian aquaculture; however, its genomic resources are still limited. We have used a streamlined bioinformatics pipeline for the de novo assembly of the genome sequence of the Japanese eel from raw Illumina sequence reads. The total assembled genome has a size of 1.15 Gbp, which is divided over 323,776 scaffolds with a...
Prompted by the reported lack of solvation effects on the oxygen affinity of fish (trout I) hemoglobin that questioned allosteric water binding in human hemoglobin A (Bellelli, A., Brancaccio, A., and Brunori, M. (1993) J. Biol. Chem. 268, 4742-4744), we have investigated solvation effects in fish and human hemoglobins by means of the osmotic stress method and allosteric analysis. In contrast t...
European eels (Anguilla anguilla) undertake spawning migrations of more than 5000 km from continental Europe and North Africa to frontal zones in the Sargasso Sea. Subsequently, the larval offspring are advected by large-scale eastward ocean currents towards continental waters. However, the Sargasso Sea is oligotrophic, with generally low plankton biomass, and the feeding biology of eel larvae ...
We show that European eels infected with the rhabdovirus EVEX (Eel Virus European X) virus, developed hemorrhage and anemia during simulated migration in large swim tunnels, and died after 1000-1500 km. In contrast, virus-negative animals swam 5500 km, the estimated distance to the spawning ground of the European eel in the Sargasso Sea. Virus-positive eels showed a decline in hematocrit, which...
The recent articles of Maetz (1971), Lahlou (1970), Mayer (1970) and Motais (1970) have synthesized the present knowledge about the functioning of the peripheral outwardly exchanging organs of osmoregulation in teleosts, namely the gills, alimentary tract and kidneys. The silver eel is very good biological material because of its high degree of euryhalinity, its ability to withstand starvation ...
Morphogenesis and physiology of tissues and organs requires planar cell polarity (PCP) systems that orient and coordinate cells and their behaviors, but the relationship between PCP systems has been controversial. We have characterized how the Frizzled and Dachsous-Fat PCP systems are connected through the Spiny-legs isoform of the Prickle-Spiny-legs locus. Two different components of the Dachs...
Dopamine system disorders ranging from movement disorders to addiction and schizophrenia involve striatal medium spiny neurons (MSNs), yet their functional connectivity has been difficult to determine comprehensively. We generated a mouse with conditional channelrhodopsin-2 expression restricted to medium spiny neurons and assessed the specificity and strength of their intrinsic connections in ...
