Polyploidization is an important mechanism that has caused many rapid speciation events and it increases genetic diversity of both plants and animals. Polyploidization occurs rarely in animals, especially in vertebrates. So far, little is known about the extent of multiple autopolyploid origins in vertebrates.

Ants play critical roles in plant protection in ecosystem by acting as predators and taking herbivores, such as parasites, as their prey items. In this predator-herbivore-plant scenario, the density or behavior of herbivore is disturbed by the predator, and thereafter, the biomass of plant is indirectly increased. This cascade is called “trophic cascade”.

| As the very front barrier to protect biological body from external environments, skin is the most frequently injured organ. Cutaneous wound healing is a dynamic, intricate and well-organized process that involves various cells types and cellular processes. Recently, a potential healing-promoting peptide, AH90, was indentified from the frog skin of Odorrana grahami by the research team of Prof. ... more |
