Part of the main thesis of the article is that unlike what we've seen from diatoms in the past:
- the growth is not a traditional growth in the reproduction sense;
- the growth appears to be linked to low phosphorous levels, not high ones.
As a result, I don't think your first comment makes any sense.
- hcarvalhoalves 12y agoIt's about nutrient imbalance, not simply excess of nutrients across the board. You can have, e.g., a high silicates and low phosphorus situation driving this particular diatom, simply because phosphorus is not the limiter (as I have already stated is the case for diatoms). If you had a different nutrient balance, there would be competition with other organisms, so no growth in the first place. Whether it's reproductive or vegetative growth is irrelevant, because the mechanism of competition is the same: it covers surfaces and outcompetes other colonies.
