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.

Abstract

The abstract is a short text containing the major hypothesis and results. The abstract should make clear why a study has been undertaken.

Check list: 1. What s interesting 2. Major theoretical background 3. Short methods 4. Major findings 5. Major implications Abstract. Current ecological theory predicts an allometric relation between the number of species with restricted range size (endemics) and area (the endemics–area relation EAR), a pattern similar to the common species–area relation (SAR). Using SARs and EARs we can estimate species loss after habitat loss. A comparison of the predictive power of both approaches (using a patch occupancy model and data from European butterflies) revealed that the EAR approach is less reliable than the SAR. Contrary to current theory it appeared that EARs are relations in their own right that describe spatial distributions of endemic species. They do not simply follow from the underlying SAR. The implications of these results for the applicability of SARs and EARs in biodiversity forecasting are discussed.

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.

Figures

Bad Use colours only if necessary.

Empty space must not be more than half of the Figure.

Use large fonts for axes descriptors.

Do not inlcude text into the Figure.

Good Unclear charts Too much empty space Too small fonts Figure captions have to be self explaining.

Figure 1: Isotopic ratios (A, B) of δ (black dots) and δ 13 C 15 N (open circles) and the respective variances (C, D) were neither significantly (all P > 0.1) linked to the numbers of islands colonized (A, C) nor to the total abundance (B, D, number of individuals).

The submission process Open access or not?

Be careful when selecting possible referees and editors!!

Don’t choose friends and regular co authors

Don’t be afraid of colour pictures In the cover letter you show why this submission is worth of being published in exactly this journal

Good journals require all the necessary raw data to be placed in electronic supplements.

No publication without the full set of raw data to reproduce the major results.

After the first decision How to answer referees?

Ecography 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 Werner Ulrich Simone Fattorini

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.
