Spawning Behavior, Egg Development, Larvae and Juvenile Morphology of Hyphessobrycon eques (Pisces: Characidae) Characidae Fishes
Hyphessobrycon eques is a famous fish for ornamental fish market and aquarium. They are inhabit in regions of Amazon and Paraguay River basin. Serpae fishs were investigated 2-3 males are chased to female, and then males attempted to simulate the females abdomen. After fertilization, eggs were kept in incubators at 28°C. The fertilized eggs had adhesive and demesal characteristics and had a mea...
متن کاملMultilocus phylogeny of cichlid fishes (Pisces: Perciformes): evolutionary comparison of microsatellite and single-copy nuclear loci.
Among vertebrates, cichlid fishes are the paradigmatic example of adaptive radiation and ecological specialization. In turn, molecular genetic studies of cichlids have focused primarily on more recently diverged groups. Here, we present an evolutionary hypothesis of the major lineages of cichlid fishes based on DNA sequence data from two nuclear loci. One marker, Tmo-4C4, is a single-copy locus...
متن کاملPisces: Anonymous Communication Using Social Networks
The architectures of deployed anonymity systems such as Tor suffer from two key problems that limit user’s trust in these systems. First, paths for anonymous communication are built without considering trust relationships between users and relays in the system. Second, the network architecture relies on a set of centralized servers. In this paper, we propose Pisces, a decentralized protocol for...
متن کاملPlanetary in Situ Capillary Electrophoresis System (pisces)
Introduction: We propose to develop PISCES, a 3kg, 2W, flightcapable microfluidic lab-on-a-chip capillary electrophoresis analyzer that is capable of injesting solid, liquid, or gas samples and performing a suite of chemical analyses with parts per trillion sensitivity. This system would be a general purpose analytical system for in situ planetary exploration. For analysis of gases or liquids, ...
متن کاملPISCES: a protein sequence culling server
PISCES is a public server for culling sets of protein sequences from the Protein Data Bank (PDB) by sequence identity and structural quality criteria. PISCES can provide lists culled from the entire PDB or from lists of PDB entries or chains provided by the user. The sequence identities are obtained from PSI-BLAST alignments with position-specific substitution matrices derived from the non-redu...
