Depositions of ammonia and nitrogen oxides have heavily increased since the mid 1900’s, and nitrogen additions in grasslands have shown to affect grass biomass, soil pH and nutrient availability. But how do these grasslands recover if nitrogen additions stop, and for how long does the added nitrogen stay in the systems?… Read more →

The females of species Callosobruchus maculatus, bean beetles, are polyandrous, which receives nuptial gifts from males during the copulations. In this project you will handle the bean beetles at close up and follow them through their life cycle to observe the effects of supplemented water on mating behaviour and reproductive success of female bean beetles.… Read more →
