Toxin of the week
Here you will find short descriptions of natural toxins. Each week will bring a new description as 'Toxin of the week' (except for breaks during summer vacation etc). All 15 fellows and other members of the NaToxAq consortium will contribute. For each description the author will be indicated.
The toxins are listed below according to date, and in the menu to the left they are sorted alphabetically.
Toxin of the week is now on an early summer break to allow the fellows to prepare for the next training event
