Berlese, Botantial: Camellias, Pieta alba

It seems like you're interested in two different topics:

1. **Berlese Funnel**: As mentioned earlier, a Berlese funnel is a tool used in biology to extract small invertebrates from soil or leaf litter. It's a useful method for studying soil ecosystems and the diversity of organisms living within them.

2. **Botanical: Camellias, Pietà alba**: Camellias are flowering plants known for their elegant blooms. "Pietà alba" likely refers to a specific cultivar or variety of Camellia. Unfortunately, I couldn't find specific information about a Camellia cultivar named "Pietà alba" in my database.

If you have any specific questions about Camellias in general or if there's something specific you'd like to know about Berlese funnels or another topic, feel free to ask!
