 <fc #​800000>​**Methodological aspects of analysing community-ecology data.**</​fc>​ It is always good to try new methods to analyze data, but at the same time, it is essential to critically ask whether these methods are really doing what we suppose them to do. Modern community ecology cannot exist without advanced numerical methods able to handle often large and complex community datasets, but we need to be aware that even the most advanced of them have certain limitations. In the lab, we focus on several methods which are commonly used by vegetation ecologists and which seems to suffer from severe limitations (community-weighted mean analysis, the effect of undersampling,​ beta diversity analysis). <fc #​800000>​**Methodological aspects of analysing community-ecology data.**</​fc>​ It is always good to try new methods to analyze data, but at the same time, it is essential to critically ask whether these methods are really doing what we suppose them to do.

-===== Research philosophy ===== 
  
-I believe that to make research successful and enjoyable at the same time, the following things are overly important: a curiosity in discovering new things, good field and lab training, creating opportunities for fruitful discussion, open data policy, and transparent analytical procedure. Good ecologist should be able to combine field and lab approaches - it is important to touch nature in the field and collect good field data, but it is also important to process, analyze and interpret data correctly, and know how to present them. 
- 
-Considering numerical analysis, my belief is in methodological simplicity – although many fancy modern (and often complex) statistical methods exist, if the choice is to be done between more advanced method and simple or traditional one, both leading to results with similar interpretation,​ my choice would be to go for the simpler one, since more people will actually understand it. Also, transparent description of analysis and honest interpretation of their outcomes is a must. Although I often work with numbers, I think about ecology at the first place - all those numerical games are here to help us to understand and interpret what's going on in nature, not the other way around.
