Pitfall traps set into the ground catch wandering species such as beetles and spiders. These have rain covers to prevent the animals from drowning

Most mRNAs decay stochastically (like the decay of radioactive isotopes), and as a result mRNA stability is usually expressed as a half- life (t½).

Hot spots of biodiversity

There is a in situ conservation. the hot spots are the richest and the most threatened reservoirs of biodiversity on the earth.

To qualify as a biodiversity hotspot, a region must meet two strict criteria:

A) It must have at least 1,500 vascular plants as endemics - which is to say, it must have a high percentage of plant life found nowhere else on the planet

B) It must have 30% or less of its original natural vegetation. In other words, it must be threatened.
