new information on sword plants
In my ongoing research into the sword plants, I came across a paper that I thought some of you might find interesting.
Ther authors are Samuli Lehtonen and Daniel Falck, two Finnish botanists. Dr. Lehtonen is perhaps the most knowledgeable botanist when it comes to the swordplant species in the Echinodorus and Helanthium genera which he and his colleagues have significantly revised through the use of DNA sequencing and cladistic analysis.
This is the first scientific study of the many cultivars--the "Kleiner Bar," "Oriental," "Rose" and similar hybrid species. Those who often ask about the origins of these variants should find this interesting. But aside from the very scientific and technical portions, the authors provide a very good summary of the development of aquaria over the past 150 years, and planted aquaria up to the present.
Can I ask? What does so much study towards plants help with? I understand fish study because we always need more knowledge on our own fish. Just a question, I was curious because I always thought that plants were mainly used as decoration and natural filtration.
There are some people who will learn what they need to be sucessful, solve problems as they come along and such. Know enough about the life in their tank to keep everything healthy.
Other people in the hobby will jump to a much more studious approach and want to know everything they can. Usually someone more interested in the natural order of things and how different groups of life interact.
Neither way is better, just depends on the persons interests. What's important is that you get as much enjoyment from the hobby as you can, that's the point of a hobby. For some people studying plants/animals is just as exciting as actually looking at/maintaining the physical tank.
