A Modest Proposal for a New Ecology Journal

I read the occasional ecology paper and ask myself how this particular paper ever got published when it is full of elementary mistakes and shows no understanding of the literature. But alas we can rarely do anything about this as individuals. If you object to what a particular paper has concluded because of its methods or analysis, it is usually impossible to submit a critique that the relevant journal will publish. After all, which editor would like to admit that he or she let a hopeless paper through the publication screen. There are some exceptions to this rule, and I list two examples below in the papers by Barraquand (2014) and Clarke (2014). But if you search the Web of Science you will find few such critiques for published ecology papers.

One solution jumped to mind for this dilemma: start a new ecology journal perhaps entitled Misleading Ecology Papers: Critical Commentary Unfurled. Papers submitted to this new journal would be restricted to a total of 5 pages and 10 references, and all polemics and personal attacks would be forbidden. The key for submissions would be to state a critique succinctly, and suggest a better way to construct the experiment or study, a new method of analysis that is more rigorous, or key papers that were missed because they were published before 2000. These rules would potentially leave a large gap for some very poor papers to avoid criticism, papers that would require a critique longer than the original paper. Perhaps one very long critique could be distinguished as a Review of the Year paper. Alternatively, some long critiques could be published in book form (Peters 1991), and not require this new journal. The Editor of the journal would require all critiques to be signed by the authors, but would permit in exceptional circumstances to have the authors be anonymous to prevent job losses or in more extreme cases execution by the Mafia. Critiques of earlier critiques would be permitted in the new journal, but an infinite regress will be discouraged. Book reviews could be the subject of a critique, and the great shortage of critical book reviews in the current publication blitz is another aspect of ecological science that is largely missing in the current journals. This new journal would of course be electronic, so there would be no page charges, and all articles would be open access. All the major bibliographic databases like the Web of Science would be encouraged to catalog the publications, and a doi: would be assigned to each paper from CrossRef.

If this new journal became highly successful, it would no doubt be purchased by Wiley-Blackwell or Springer for several million dollars, and if this occurred, the profits would accrue proportionally to all the authors who had published papers to make this journal popular. The sale of course would be contingent on the purchaser guaranteeing not to cancel the entire journal to prevent any criticism of their own published papers.

At the moment criticism of ecological science does not occur for several years after a poor paper is published and by that time the Donald Rumsfeld Effect would have occurred to apply the concept of truth to the conclusions of this poor work. For one example, most of the papers critiqued by Clarke (2014) were more than 10 years old. By making the feedback loop much tighter, certainly within one year of a poor paper appearing, budding ecologists could be intercepted before being led off course.

This journal would not be popular with everyone. Older ecologists often strive mightily to prevent any criticism of their prior conclusions, and some young ecologists make their career by pointing out how misleading some of the papers of the older generation are. This new journal would assist in creating a more egalitarian ecological world by producing humility in older ecologists and more feelings of achievements in young ecologists who must build up their status in the science. Finally, the new journal would be a focal point for graduate seminars in ecology by bringing together and identifying the worst of the current crop of poor papers in ecology. Progress would be achieved.

On Improving Canada’s Scientific Footprint – Breakthroughs versus insights

A Survey of Strong Inference in Ecology Papers: Platt’s Test and Medawar’s Fraud Model

10 Replies

In 1897 Chamberlin wrote an article in the Journal of Geology on the method of multiple working hypotheses as a way of experimentally testing scientific ideas (Chamberlin 1897 reprinted in Science). Ecology was scarcely invented at that time and this has stimulated my quest here to see if current ecology journals subscribe to Chamberlin’s approach to science. Platt (1964) formalized this approach as “strong inference” and argued that it was the best way for science to progress rapidly. If this is the case (and some do not agree that this approach is suitable for ecology) then we might use this model to check now and then on the state of ecology via published papers.

I did a very small survey in the Journal of Animal Ecology for 2015. Most ecologists I hope would classify this as one of our leading journals. I asked the simple question of whether in the Introduction to each paper there were explicit hypotheses stated and explicit alternative hypotheses, and categorized each paper as ‘yes’ or ‘no’. There is certainly a problem here in that many papers stated a hypothesis or idea they wanted to investigate but never discussed what the alternative was, or indeed if there was an alternative hypothesis. As a potential set of covariates, I tallied how many times the word ‘hypothesis’ or ‘hypotheses’ occurred in each paper, as well as the word ‘test’, ‘prediction’, and ‘model’. Most ‘model’ and ‘test’ words were used in the context of statistical models or statistical tests of significance. Singular and plural forms of these words were all counted.

This is not a publication and I did not want to spend the rest of my life looking at all the other ecology journals and many issues, so I concentrated on the Journal of Animal Ecology, volume 84, issues 1 and 2 in 2015. I obtained these results for the 51 articles in these two issues: (number of times the word appeared per article, averaged over all articles)

Explicit hypothesis and alternative hypotheses			“Hypothesis”	“Test”	“Prediction”	“Model”
Yes	22%	Mean	3.1	7.9	6.5	32.5
No	78%	Median	1	6	4	20
No. articles	51	Range	0-23	0-37	0-27	0-163

There are lots of problems with a simple analysis like this and perhaps its utility may lie in stimulating a more sophisticated analysis of a wider variety of journals. It is certainly not a random sample of the ecology literature. But maybe it gives us a few insights into ecology 2015.

I found the results quite surprising in that many papers failed Platt’s Test for strong inference. Many papers stated hypotheses but failed to state alternative hypotheses. In some cases the implied alternative hypothesis is the now-discredited null hypothesis (Johnson 2002). One possible reason for the failure to state hypotheses clearly was discussed by Medawar many years ago (Howitt and Wilson 2014; Medawar 1963). He pointed out that most scientific papers were written backwards, analysing the data, finding out what it concluded, and then writing the introduction to the paper knowing the results to follow. A significant number of papers in these issues I have looked at here seem to have been written following Medawar’s “fraud model”.

But make of such data as you will, and I appreciate that many people write papers in a less formal style than Medawar or Platt would prefer. And many have alternative hypotheses in mind but do not write them down clearly. And perhaps many referees do not think we should be restricted to using the hypothetical deductive approach to science. All of these points of view should be discussed rather than ignored. I note that some ecological journals now turn back papers that have no clear statement of a hypothesis in the introduction to the submitted paper.

The word ‘model’ is the most common word to appear in this analysis, typically in the case of a statistical model evaluated by AIC kinds of statistics. And the word ‘test’ was most commonly used in statistical tests (‘t-test’) in a paper. Indeed virtually all of these paper overflow with statistical estimates of various kinds. Few however come back in the conclusions to state exactly what progress has been made by their paper and even less make statements about what should be done next. From this small survey there is considerable room for improvement in ecological publications.

Citation Analysis Gone Crazy

2 Replies

Perhaps we should stop and look at the evils of citation analysis in science. Citation analysis began some 15 or 20 years ago with a useful thought that it might be nice to know if one’s scientific papers were being read and used by others working in the same area. But now it has morphed into a Godzilla that has the potential to run our lives. I think the current situation rests on three principles:

Your scientific ability can be measured by the number of citations you receive. This is patent nonsense.
The importance of your research is determined by which journals accept your papers. More nonsense.
Your long-term contribution to ecological science can be measured precisely by your h–score or some variant.

These principles appeal greatly to the administrators of science and to many people who dish out the money for scientific research. You can justify your decisions with numbers. Excellent job to make the research enterprise quantitative. The contrary view which I might hope is held by many scientists rests on three different principles:

Your scientific ability is difficult to measure and can only be approximately evaluated by another scientist working in your field. Science is a human enterprise not unlike music.
The importance of your research is impossible to determine in the short term of a few years, and in a subject like ecology probably will not be recognized for decades after it is published.
Your long-term contribution to ecological science will have little to do with how many citations you accumulate.

It will take a good historian to evaluate these alternative views of our science.

This whole issue would not matter except for the fact that it is eroding science hiring and science funding. The latest I have heard is that Norwegian universities are now given a large amount of money by the government if they publish a paper in SCIENCE or NATURE, and a very small amount of money if they publish the same results in the CANADIAN JOURNAL OF ZOOLOGY or – God forbid – the CANADIAN FIELD NATURALIST (or equivalent ‘lower class’ journals). I am not sure how many other universities will fall under this kind of reward-based publication scores. All of this is done I think because we do not wish to involve the human judgment factor in decision making. I suppose you could argue that this is a grand experiment like climate change (with no controls) – use these scores for 30 years and then see if they worked better than the old system based on human judgment. How does one evaluate such experiments?

NSERC (Natural Sciences and Engineering Research Council) in Canada has been trending in that direction in the last several years. In the eternal good old days scientists read research proposals and made judgments about the problem, the approach, and the likelihood of success of a research program. They took time to discuss at least some of the issues. But we move now into quantitative scores that replace human judgment, which I believe to be a very large mistake.

I view ecological research and practice much like I think medical research and medical practice operate. We do not know how well certain studies and experiment will work, any more than a surgeon knows exactly whether a particular technique or treatment will work or a particular young doctor will be a good surgeon, and we gain by experience in a mostly non-quantitative manner. Meanwhile we should encourage young scientists to try new ideas and studies, to give them opportunities based on judgments rather than on counts of papers or citations. Currently we want to rank everyone and every university like sporting teams and find out the winner. This is a destructive paradigm for science. It works for tennis but not for ecology.

Is Ecology like Economics?

2 Replies

One statement in Thomas Piketty’s book on economics struck me as a possible description of ecology’s development. On page 32 he states:

“To put it bluntly, the discipline of economics has yet to get over its childish passion for mathematics and for purely theoretical and often highly ideological speculation at the expense of historical research and collaboration with the other social sciences. Economists are all too often preoccupied with petty mathematical problems of interest only to themselves. This obsession with mathematics is an easy way of acquiring the appearance of scientificity without having to answer the far more complex questions posed by the world we live in.”

If this is at least a partially correct summary of ecology’s history, we could argue that finally in the last 20 years ecology has begun to analyze the far more complex questions posed by the ecological world. But it does so with a background of oversimplified models, whether verbal or mathematical, that we are continually trying to fit our data into. Square pegs into round holes.

Part of this problem arises from the hierarchy of science in which physics and in particular mathematics are ranked as the ideals of science to which we should all strive. It is another verbal model of the science world constructed after the fact with little attention to the details of how physics and the other hard sciences have actually progressed over the past three centuries.

Sciences also rank high in the public mind when they provide humans with more gadgets and better cars and airplanes, so that technology and science are always confused. Physics led to engineering which led to all our modern gadgets and progress. Biology has assisted medicine in continually improving human health, and natural history has enriched our lives by raising our appreciation of biodiversity. But ecology has provided a less clearly articulated vision for humans with a new list of commandments that seem to inhibit economic ‘progress’. Much of what we find in conservation biology and wildlife management simply states the obvious that humans have made a terrible mess of life on Earth – extinctions, overharvesting, pollution of lakes and the ocean, and invasive weeds among other things. In some sense ecologists are like the priests of old, warning us that God or some spiritual force will punish us if we violate some commandments or regulations. In our case it is the Earth that suffers from poorly thought out human alterations, and, in a nutshell, CO₂ is the new god that will indeed guarantee that the end is near. No one really wants to hear or believe this, if we accept the polls taken in North America.

So the bottom line for ecologists should be to concentrate on the complex questions posed by the biological world, and try first to understand the problems and second to suggest some way to solve them. Much easier said than done, as we can see from the current economic mess in what might be a sister science.

Back to p-Values

1 Reply

Alas ecology has slipped lower on the totem-pole of serious sciences by an article that has captured the attention of the media:

Low-Décarie, E., Chivers, C., and Granados, M. 2014. Rising complexity and falling explanatory power in ecology. Frontiers in Ecology and the Environment 12(7): 412-418. doi: 10.1890/130230.

There is much that is positive in this paper, so you should read it if only to decide whether or not to use it in a graduate seminar in statistics or in ecology. Much of what is concluded is certainly true, that there are more p-values in papers now than there were some years ago. The question then comes down to what these kinds of statistics mean and how this would justify a conclusion captured by the media that explanatory power in ecology is declining over time, and the bottom line of what to do about falling p-values. Since as far as I can see most statisticians today seem to believe that p-values are meaningless (e.g. Ioannidis 2005), one wonders what the value of showing this trend is. A second item that most statisticians agree about is that R² values are a poor measure of anything other than the items in a particular data set. Any ecological paper that contains data to be analysed and reported summarizes many tests providing p-values and R² values of which only some are reported. It would be interesting to do a comparison with what is recognized as a mature science (like physics or genetics) by asking whether the past revolutions in understanding and prediction power in those sciences corresponded with increasing numbers of p-values or R² values.

To ask these questions is to ask what is the metric of scientific progress? At the present time we confuse progress with some indicators that may have little to do with scientific advancement. As journal editors we race to increase their impact factor which is interpreted as a measure of importance. For appointments to university positions we ask how many citations a person has and how many papers they have produced. We confuse scientific value with some numbers which ironically might have a very low R² value as predictors of potential progress in a science. These numbers make sense as metrics to tell publication houses how influential their journals are, or to tell Department Heads how fantastic their job choices are, but we fool ourselves if we accept them as indicators of value to science.

If you wish to judge scientific progress you might wish to look at books that have gathered together the most important papers of the time, and examine a sequence of these from the 1950s to the present time. What is striking is that papers that seemed critically important in the 1960s or 1970s are now thought to be concerned with relatively uninteresting side issues, and conversely papers that were ignored earlier are now thought to be critical to understanding. A list of these changes might be a useful accessory to anyone asking about how to judge importance or progress in a science.

A final comment would be to look at the reasons why a relatively mature science like geology has completely failed to be able to predict earthquakes in advance and even to specify the locations of some earthquakes (Steina et al. 2012; Uyeda 2013). Progress in understanding does not of necessity dictate progress in prediction. And we ought to be wary of confusing progress with p-and R² values.

On Journal Referees

3 Replies

I have been an editor of enough ecological journals to know the problems of referees first hand. The start is to try to find a referee for a particular paper. I would guess now that more than two-thirds of scientists asked to referee a potential paper say they do not have time. This leads to another question of why no one has any time to do anything, but that is a digression. If one is fortunate you get 2 or 3 good referees.

The next problem comes when the reviews of the paper come back. Besides dealing with the timing of return of the reviews, there are four rules which ought to be enforced on all referees. First, review the potential paper as it is. Do not write a review saying this is what you should have written- that is not your job. Second, if the paper is good enough, be positive in making suggestions for improvement. If it is not good enough in your opinion, try to say so politely and suggest alternate journals. Perhaps the authors are aiming for a journal that is too prestigious. Third, do not say in so many words that the author should cite the following 4 papers of mine…. And fourth, do not make ad hominem attacks on the authors. If you do not like people from Texas, this is not the place to take it out on the particular authors who happen to live there.

Given the reviews, the managing editor for the paper ought to make a judgment. Some reviews do not follow the four rules above. A good editor discards these and puts a black mark on the file of that particular reviewer. I would not submit a referee’s review to the authors if it violated any of the above 4 rules. I have known and respected editors who operated this way in the past.

The difficulty now is that ecological journals are overrun. This is driven in part by the desire to maximize the number of papers one publishes in order to get a job, and in part by journals not wanting to publish longer papers. Journals do not either have the funding or the desire to grow in relation to the number of users. This typically means that papers are sent out for reviews with a note attached saying that we have to reject 80% or so of papers regardless of how good they are, a rather depressing order from above. When this level of automatic rejection is reached, the editor in chief has the power to reject any kinds of papers not in favour at the moment. I like models so let’s publish lots of model papers. Or I like data so let’s publish only a few model papers.

One reason journals are overrun is that many of the papers published in our best ecology journals are discussions of what we ought to be doing. They may be well written but they add nothing to the wisdom of our age if they simply repeat what has been in standard textbooks for the last 30 years. In days gone by, many of these papers I think might have been given as a review seminar, possibly at a meeting, but no one would have thought that they were worthy of publication. Clearly the editors of some of our journals think it is more important to talk about what to do rather than to do it.

I think without any empirical data that the quality of reviews of manuscripts has deteriorated as the number of papers published has increased. I often have to translate reviews for young scientists who are devastated by some casual remark in a review. “Forget that nonsense, deal with this point as it is important, ignore this insult to your supervisor, go have a nice glass of red wine and relax, ……”. One learns how to deal with poor reviews.

I have been reading Bertram Murray’s book “What Were They Thinking? Is Population Ecology a Science?” (2011), unfortunately published after he died in 2010. It is a long diatribe about reviews of some of his papers and it would be instructive for any young ecologist to read it. You can appreciate why Murray had trouble with some editors just from the subtitle of his book, “Is Population Ecology a Science?” It illustrates very well that even established ecologists have difficulty dealing with reviews they think are not fair. In defense of Murray, he was able to get many of his papers published, and he cites these in this book. One will not come away from this reading with much respect for ornithology journals.

I think if you can get one good, thoughtful review of your manuscript you should be delighted. And if you are rejected from your favourite journal, try another one. The walls of academia could be papered with letters of rejection for our most eminent ecologists, so you are in the company of good people.

Meanwhile if you are asked to referee a paper, do a good job and try to obey the four rules. Truth and justice do not always win out in any endeavour if you are trying to get a paper published. At least if you are a referee you can try to avoid these issues.

Research funding for women

NSERC funding by gender

Success rates are similar, but women still get less

Judith Myers UBC

NSERC has over the years provided data on request for the Discovery Grant Program for Ecology and Evolution broken down by both gender and different categories of applicants, eg. established, new first renewals etc. In 2008, I summarized these data for presentation at the Canadian Coalition of Women in Science, Engineering, Trades and Technology (CCWESTT). This can be found as “NSERC Discovery Grant Statistics for males and females 2002 – 2008 at http://ww.ccwestt.org/Home/tabid/36/Default.aspx. That analysis showed a consistent trend for women to receive smaller grants than men with the exception of new applicants in 2007 and 2008 for which grants for women were larger.

Here, I analyze the NSERC data from 2009 and 2013. I show that success rates for grant applications are similar between men and women; however, the trend for women to receive lower grant funding on average continues.

Figure 1. Proportion applicants successful in 2009 and 2013 competitions. Numbers of applicants are given in the legend. “Renewal” is first time renewal and “first” includes those applying for the first time and applicants that were previously unsuccessful in their first attempt. Horizontal lines indicate overall average success rate, 73% in 2009 and 63% in 2013. Number of applicants is at the top of the bar.

Figure 1 shows that the overall success rate in 2013 is approximately 10% lower than in 2009, the successes of males and females are similar, and the success rate across categories is similar although first renewal success is lower and is lowest for females. Given the importance of this stage for the establishment of the future careers of these applicants this trend is of concern.

Figure 2. Average grants of different categories of applicants for NSERC Discovery Grants in 2009 and 2013. The horizontal line indicates the overall average grants grant size, $33 351 (grants $5028 less for females than males) in 2009 and $31 828 ($6650 less for females than males) in 2013.

Figure 2 shows that the trend seen in earlier data continues with grants of males being larger than those of females by a substantial amount. A factor here is that there are no female high fliers who have substantially larger grants than the average, and overall median grants are about the same for males and females. I have not taken accelerator grants into consideration here.

Given that females are on average receiving approximately $6500 less than their male colleagues, it would be interesting to know how this is translated into productivity measured as the number of publications in one year. For an indication of how publications relate to grant sizes, I selected individuals from the NSERC results for 2013 taking from a range of grant sizes but including those with the largest grants and a sampling from the lower grant sizes. I then used Web of Science to determine the number of publications for the year 2012-2013 for each chosen individual.

Figure 3. Size of grant awarded in 2013 and number of publications in 2012-2013 for an arbitrary sample of grantees. Neither relationship is significant, but that for males is influenced by the high publication number for two of the male “high fliers”.

The lack of relationship between yearly publication rates and grant size shows that productivity does not relate strongly to funding success. No female received a grant of more than $50 000 in 2013 so the range of the data is less for them. For males, high publication numbers for two “high fliers” cause a weak upward trend in the relationship of publications to funding, but average publication numbers for four “high fliers” pulls this relationship down. For these selected data the average number of publications for males was 10.5 and for females 9.1. Removing the data for “high fliers” in the male data sets results in a slightly higher grant size for males than for females but only 7 publications on average for males compared to 9 for females for similar funding levels. Although this is a small and selected data set, it likely reflects the overall pattern for little relationship between grant size and publication numbers. Similarly Lortie et al. 2012 (Oikos 121: 1005–1008) found that for the mostly highly-funded North American ecologists and environmental scientists, citations per paper were not related to increased levels of funding although for NSERC funded researchers there was a weak relationship. Fortin and Currie (2013) found that the number of papers, highest times cited, and number of high impact articles were only weakly related to NSERC funding levels for Animal Biology, Chemistry and Ecology and Evolution (PLOS ONE, DOI: 10.1371). Missing from these analyses are the data for individuals who receive no funding. Thus the reduced proportion of successful renewals in the current funding environment, and the slightly reduced success of first time renewals are not reflected in these evaluations of research productivity. A recent study of global patterns of publications and citations shows that women publish less than men particularly in areas in which research is expensive, they are less likely to participate in international collaborations and are less likely to be first or last authors on papers (Larivière et al. 2013. Nature 504:211 – 213). There are many factors involved here.

We do not have data on HQP numbers, a metric that is heavily weighted in the NSERC Discovery Grant evaluation. It is likely that the reduced funding level for females results in fewer HQP for them and this could have a strong impact on average funding from NSERC and publication numbers in the future.

In conclusion the new system of Discovery Grant evaluation appears to result in more similar levels of funding across categories but does not remove the bias towards larger grants on average for males. The impact on research productivity of the 37% of applicants that receive no funding as a result of the lower success rate is not easy to evaluate, but data do not support the hypothesis that higher funding for fewer individuals increases Canada’s research productivity.
