Badanie zbiorowisk glonów na płycie rafowej w El Jadida pozwoliło zidentyfikować łącznie 127 taksonów podzielonych na 3 grupy systematyczne: 20 Chlorophyceae (16%), 24 Fucophyceae (19%) i 83 Rhodophycea (65%). Analiza flory morskiej badanego regionu wykazała, że z jednej strony 84,25% gatunków należy do flory atlantycko-śródziemnomorskiej, 12,6% gatunków występuje wyłącznie w Atlantyku, a jedynie 3,15% pochodzi z Morza Śródziemnego; z drugiej strony 61,42% gatunków to gatunki fotofilne, a 38,58% to gatunki sciafilne. 82,68% taksonów wykazuje powinowactwo do strefy infralitoralnej, a 17,32% do strefy mediolitoralnej. Badania nad brunatnicą Fucus spiralis wykazały, że jej średnia wielkość waha się od minimum 10 cm w styczniu do maksimum 22,8 cm w lipcu, a maksymalną świeżą biomasę odnotowano między lipcem a wrześniem (6 kg/m²), natomiast minimum odnotowano w połowie stycznia (2 kg/m²). Badania nad Laminaria ochroleuca wykazały, że biomasa osiągała maksimum pod koniec czerwca 2005 r. (24,57 kg/m² (PF)). Połów tego gatunku mógłby odbywać się przez całe lato. Monitorowanie zawartości niektórych pierwiastków śladowych wykazało duże bogactwo tych pierwiastków u obu gatunków.

  • 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...
  • Advances in Flavivirus Research
    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. 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...

    Joëlle Roche
    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 ...

There has been progress in the treatment of acute m...
