Leptodactylus labyrinthicus (Spix, 1824) (Amphibia, Anura, Leptodactilidae), dessen gebräuchlichster Name Pfefferfrosch oder Gia ist, wurde 1824 von Spix als Rana labyrinthica beschrieben und als neue Gattung (Leptodactylus labyrinthicus) neu definiert (CEI, 1980). Die Population des Pfeilgiftfrosches in Brasilien ist aufgrund der ständigen Verschlechterung der natürlichen Ökosysteme, insbesondere durch anthropogene Eingriffe, Raubtierjagd und die Einführung exotischer Arten, rückläufig. Das Wissen über den Fortpflanzungszyklus ist von grundlegender Bedeutung für das Verständnis der Lebenszyklusstrategien von Lebewesen. Die Ausbreitung von Wirbeltieren hängt von der Anpassung dieser Zyklen an die Umwelt ab. Und für die Erhaltung des Pfeffersalzfrosches kann dieses Wissen bei phylogenetischen Analysen dieser Art hilfreich sein. Die Bedeutung des Pfeilgiftfrosches für das brasilianische Ökosystem und der Mangel an Studien über das Sperma dieser Art rechtfertigen die Entwicklung dieser Arbeit, deren Hauptziel es war, die Eigenschaften des Spermas und der Spermatozoen des Pfeilgiftfrosches zu bewerten.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...
