Hello all! Here is something I have been interested in for a while. There seems to be a theory going around that there are certain species of bromeliad that are carnivorous. The idea is that since bromeliads take in nutrients through their water-tanks, they may also take in nutrients from living organisms that try to make the water-tanks their home -- almost like a pitcher plant. Do you think that this represents an evolutionary middle-ground in plant carnivory?

Welcome!

The bromeliads are not intent upon killing their 'swimmers' (like pitcher plants or sundews) but if one dies or (heaven forbid) poops in the pool, the plant will use those nutrients to its benefit. Any plant, if a dead bug or animal died at its feet, would use the nutrients from the rotting corpse. So no, I wouldn't classify them as carnivorous plants.

Interesting! Although I have read about a case of C. berteroniana and B. reducta adapting a slippery rosette that makes unweary insects lose their footing...

I have too but feel the authors were 'reaching' to try to prove something that may not exist. I need a lot more scientific studies to be convinced. On the other hand, if a plant developed a slippery slope and it worked to its advantage, ...
