UNLABELLED • PREMISE OF THE STUDY Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, howe...
The family Pteridaceae in Iraq comprises 6 species belongs5 genera. These occur a diverse range of environments including humid temperate forests, the falls waterfalls and shrub lands. fern was collected from different locations environment geographical habitats during seasons two districts Iraqi Kurdistan. anatomical structure aerial parts were studied.

Organelle movement and positioning are essential for proper cellular function. A nucleus moves dynamically during cell division and differentiation and in response to environmental changes in animal, fungal, and plant cells. Nuclear movement is well-studied and the mechanisms have been mostly elucidated in animal and fungal cells, but not in plant cells. In prothallial cells of the fern Adiantu...
Although ctenophores can be conspicuous components of the plankton in coastal marine ecosystems, only six species have been formally described from around South Africa. Using photographs local community scientists, we add a further three ( Cestum veneris, Beroe forskalii ?, Ocyropsis maculata ?) and morphospecies to regional fauna. These additions suggest that Africa has ctenophore fauna is amo...
