Conclusion
Concluding, in my opinion the doctoral proposal of Łukasz Banasiak achieves the level
defined by art. 11, 12, 13, 14, 15 of the Polish law on scientific degrees and titles (Dz. U. Nr
65/03 pos. 595/; March 2003). I propose to pass the proposal to subsequent steps.

The study of diversity patterns of ground beetles on lake islands
M. Zalewski & W. Ulrich*
The question how abiotic and biotic factors influence regional patterns of species diversity is central to
macroecology. However, high quality data sets that allow for the study of important patterns of species
diversity simultaneously are still scarce.
Here we present first results of a holistic research program aimed to infer and to model species
interactions of a metacommunity of Carabidae on 15 lake islands and two mainland sites of a Mazurian
lake (Northern Poland)[1,2]. Our results about core and satellite species (Fig. 1) and associated
abundance distributions and patterns of co-occurrence (Tab. 1) strongly indicate that current models of
niche division, species segregation and co-occurrence aimed to model regional diversity might dismiss
important aspects if they do not explicitly refer to differential patterns of dispersal.
Table 1. Ground beetles found at the 17 study sites, island area, the number of
traps used, observed species (Sobs), rarefied species number and its standard
deviation, estimated total species number, and the number of individuals
found.
Tables descriptions should be self-explanatory and
highlight the major results.

Introduction
First of all: try to tell a story!!!
The introduction should shortly discuss the state of art and the theories the study is
based on.
Describe the motivation for the present study.
Do not review the literature extensively but discuss all of the relevant literature
necessary to put the present paper into a broader context.
Shortly review and explain the hypotheses to be tested
Explain who might be interested in the study.
Explain why this study is worth reading!
Show that you are familiar with the current literature and the state of art.
Do not repeat textbook knowledge!!
Be careful with the literature you cite.
Do not cite questionable sources!!
Particularly be carful with the citation of internet pages.
Do not cite unpublished work.
Do not use formulations and text excerpts of others (including internet sources) without
citation!!
Build your text in a logical way and clarify each step in the argument. Take care of logic!!!!
Methods
A short description of the study area (if necessary), the experimental or observational
techniques used for data collection, and the techniques of data analysis used.
Indicate the limits of the techniques used.
•
•
•
•
•
Place necessary study site descriptions into the electronic appendix.
Be as short as possible but be precise!!
Do not describe standard methods.
When using software provide the parameter settings.
Do only describe non-standard statistical methods.
• Provide information on missing data.
• Provide information on measurement errors and methodological drawbacks.
• Provide always error descriptors for central tendencies!!
Never use the same data for hypothesis development and hypothesis testing!!!
Methods
Study Area
From 2005 to 2010, we studied the initial vegetation succession in the artificial catchment
Chicken Creek in north-eastern Germany (Lusatia region). Constructed in 2004/
2005 as headwaters of the Chicken Creek stream, this 6-ha study site is part of the
reclamation of an open-cast lignite mine. Sand or loamy material originating from
Pleistocene sediments was used for construction of the 1– 3-m top layer of the catchment
(details in Gerwin et al. 2009).
Place all necessary details in additional electronic supplements.
Results
This section should contain a description of the results of your study.
Here the majority of tables and figures should be placed.
Do not double data in tables and figures.
Do not interpret or discus the results.
3. Results
Table 1 shows the major results. Amino acid concentration was measured twice and
did not correlate with metabolic rate (Fig. 1). Probably the low temperature limited
metabolic rate because there was a significant correlation between temperature
and metabolic rate (r = -0.5465, F = 3.5, P(no correlation) = 0.456; not shown).
Average amino acid concentration was low and is shown in Fig. 2. Metabolic rates
are given in Tab. 2 and Fig. 3.
3. Results
Metabolic rate (Supplement A) did not correlate (r = 0.36; P > 0.3) with the
generally low (Supplement B) amino acid concentrations but was negatively linked
to ambient temperature (r = -0.55, P < 0.05; Fig. 1 ).
Discussion
This part should be the longest part of the paper.
Discuss your results in the light of current theories and scientific belief.
Compare the results with the results of other comparable studies.
Again discuss why your study has been undertaken and what is new.
Discuss also possible problems with your data and misconceptions.
Give hints for further work.
Do not repeat results!
Refer to each part of the introduction.
Again take care of the logic!!!!
Each sentence of a paragraph should be the logical consequence of
the previous sentence.

Editor in Chief
Dr. Carsten Rahbek
Dear Dr. Rahbek:
Thank you very much for the reviews and your willingness to accept a revised version of our
paper ECOG-00188 entitled “Longitudinal gradients in the phylogenetic community
structure of European Tenebrionidae”. Below we answer to the suggestions and comments
of the referees and the handling editor, Dr. Wiegand.
Handing editor
I have now received two excellent reviews of your manuscript ECOG-00188 “Longitudinal
gradients in the phylogenetic community structure of European Tenebrionidae
(Coleoptera) do not coincide with the major routes of postglacial colonization” submitted
to Ecography. As…
We have included the suggested analysis and the new Figure. Please see our detailed
answers to each comment/suggestion below.
- References … Cooper et al. 2008 citation is missing from the list. Please, check for
additional errors as well.
We now included Cooper et al. and checked the reference list once again.
- Table 1 … please, explain in the table caption what χ2 metric represents in your case
Done.
- Table 2 … please, give R2 values for the presented relationships to show their strength
We included these values in Tabs. 2 and 3.
- Figure1 and Figure 2 … place these figures in the appendix, please, and use a map or
other convenient graphics instead
Here we do not agree with the referee. Both figures contain important information and
are central to our interpretation. In our view they are clear. However, we leave this point
and the question whether to include a map to the decision of the editor.
We hope that our revised version matched the requirements of Ecography.
Sincerely

Review
Review of XXX: Simulation of virtual population models
Yes, there are submissions that beam us back even before the golden age of theoretical ecology. In
these dark times mathematicians thought that all ecologists were stupid and ecologists believed that
old Isaac is the ultimate goal. But then Robert MacArthur appeared and told us that we are not stupid
and that random numbers rule the world. Later on at least we younger guys believed in the
Tallahassee mafia and its guru Dan Simberloff told us not to trust in basic statistics and any rules. Since
then we rack our brains about the best null and swap and swap and swap…. After destruction new
hope and the metapopulation lurked behind the Finish islands. Today we are back to the basics where
neutral fractality is fractal neutrality and species do not exist but Fokker –Planck and Price equations
rule the world. Today ecologists speak Spanish and read Kimura and Hubbell (they rarely read Gould
and Krebs).
Luckily all these complications do not worry the present author and she decided to stay in the dark
times of equilibrium functions to demonstrate the surprised ecologists of that times her new toy in
form of a manual of some internet game (by the way, don’t you know the Ecobeaker package for
undergraduate pupils, it’s much better). And we learn that animals may have one or more offspring.
Surely, otherwise we won’t exist (didn’t you hear anything about resource allocation and William
Hamilton?). We also learn that simulations provide standard deviations (I prefer randomization and
bootstrapping of real population data). And we learn from the title that the author wants to simulate
virtual models (or virtual populations or virtual virtuality?). Oh yeah, this needs real second life virtual
computers!
In conclusion, I strongly advice reading a concise history of ecology before publishing anything. Beam
me up, Scotty.
