When frustration becomes serendipitous – My second most cited paper

For most of the 1980s and the early 1990s I worked for the UK Forestry Commission as a research and advisory entomologist. As a civil servant I was subjected to a lot more rules than I am now as a university academic. The most frustrating set of rules in my mind, were those associated with publishing papers. The initial consultation with a statistician before your experiment was planned and any subsequent collaboration with the analysis was very sensible, and I had no problems with that part of the process at all. Our statisticians were very good in that they helped you decide the analysis but expected you to learn GenStat (the Forestry Commission standard statistics programme) and do it yourself unless you were really stuck.

The next bit was the frustrating part. When it came to writing papers you first submitted your paper to your line manager. They then read your paper, very frustrating indeed for me, as my immediate boss considered papers a very low priority and it could be several months before he got around to passing it back with comments and suggestions. Then it was passed to a member of one of the other department such as silviculture, tree breeding or pathology for them to read and make comments. The idea behind this being that it helped make the paper accessible to a wide audience, again a good idea. The problem at this stage was that once again your paper was likely to be a low priority, so yet more delay. Once that was done you then had to submit your paper to the Chief Research Office for him to read and comment on, so once again yet more delay. This meant that quite often it was a year before you actually were able to submit your paper to a journal, which could be deeply frustrating to say the least.

Frustrated

In 1986 a new journal to be published by the British Ecological Society was announced, Functional Ecology. In those days, the dreaded Impact Factors had not yet raised their ugly heads, and one tended to publish in journals relevant to your discipline, or, as in this case, the fancy took you.  I thought it would be cool to publish in the first issue of the first volume of this new journal.  I therefore set to work, with the help of one of our statisticians to produce a paper about life history parameters of the pine beauty moth, from a more ecological point of view and not from the more applied view-point of it as a forest pest (my job remit). I was very proud of the paper and confess to having got somewhat carried away in the discussion, so much so, that it was suggested by all who read it in the very lengthy internal appraisal process, that most of the discussion should be cut as being too far away from the main story. As the process had taken so long already I decided to go with the flow and eventually submitted my paper about a year after first writing it, incidentally giving my statistician a co-authorship. It was accepted and did indeed appear in the first volume of Functional Ecology, albeit the last of the year (Leather & Burnand, 1987)! It has to date (14th October 2015) being cited 53 times, by no means a disgrace, but certainly not my second-most cited paper.

I mentioned earlier that I was really proud of my discussion and I decided that I was going to publish it regardless. I reworked it slightly and submitted it to Oikos as a Forum piece, taking the calculated risk of not submitting it through the official Forestry Commission system. My reasoning was, that a), it was unlikely to be read by anyone in the Forestry Commission, being a very ecological journal, and b), if challenged I would say that it had already been seen by the powers that be, albeit not officially. To my relief it was accepted as is (Leather, 1988) and my immediate boss never mentioned it. To my surprise and delight this is now my second-most cited paper, having so far acquired 207 citations and still picks up a reasonable number of cites every year. I guess that I should actually be grateful to all those internal referees who insisted that I cut my discussion down so drastically.

Where have all the insects gone? Perhaps they were deterred by Editorial Board composition!

In a recent Animal Ecology in Focus blog post, the Executive Editor of Journal of Animal Ecology, Ken Wilson, made a spirited response to my well documented Twitter comments about the lack of insect papers in the journal and also highlighted by me in the recent JAE Virtual issue which I compiled to celebrate National Insect Week 2014. Ken had been somewhat sceptical about my claims but when he analysed the data he found, much to my gratification 😉 that I was correct; the number of insect papers published by Journal of Animal Ecology, has indeed fallen steeply since the 1970s, and this was true for two of the other journals from the British Ecological Society’s (BES) portfolio, Journal of Applied Ecology and Functional Ecology.

Ken also looked at Ecology, published by the Ecological Society of America and Oikos, published by The Nordic Society Oikos. In both cases he found that insects and other invertebrates had held their own over the last forty years.

Ken refutes any claim of editorial bias, acceptance rates for insect papers are similar to those for vertebrate papers, and hypothesizes that the reason insect and invertebrate papers have declined in the BES journals is due to the subject areas favoured by the journal i.e. demography, evolutionary ecology, spatial ecology and disease ecology; fields that in the UK are dominated by vertebrate ecologists and/or the rapidly decreasing number of entomologists employed by UK universities. This may be a contributing factor, but entomologists in the UK and worldwide also work in these fields, so it cannot be the whole story. He urges the entomological community to submit more papers to the journal in order to redress the balance.

Interestingly enough, the response among the Twitter community seemed to show that most entomologists did not perceive Journal of Animal Ecology as being insect friendly and in some cases it was seen not just as a vertebrate journal, but as an ornithological one, echoing a comment made by Jeremy Fox over at the Dynamic Ecology blogThese data are consistent with the rumor I heard back when I was a postdoc, that JAE got so many bird-related submissions that they had to work hard to avoid turning into an ornithology journal.”

So what has changed since the 1970s? Back when I was a PhD student, ecological entomologists had no hesitation in submitting their papers to Journal of Animal Ecology, Oecologia and Oikos, or if their work was applied, then Journal of Applied Ecology was a first choice venue, with Annals of Applied Biology also considered a logical place to submit entomological papers. Looking back at the papers published from my PhD work, I find that I published one in Journal of Animal Ecology (Wellings et al, 1980), one in Journal of Applied Ecology (Leather et al, 1984 (back in the early 1980s Journal of Applied Ecology could take over a year to make a decision), and three in Oecologia (Leather et al, 1983a,b; Ward et al., 1984). Of my other more applied work, three were published in the Annals of Applied Biology and the rest in specialised entomological journals, (five in Entomologia experimentalis et applicata, and three in the Journal of Applied Entomology).

So why did entomologists have no hesitation in sending their papers to Journal of Animal Ecology and Journal of Applied Ecology in the 1970s. A quick look at the Editorial Boards of the two journals, admittedly much smaller than those of today, shows us that in 1977 (when I started my PhD), Roy Taylor (entomologist) and Malcolm Elliott (fresh water ecologist) were editors of the former, with and editorial board consisting of T B Bagenal (fish), R A Kempton (statistics), Mike Hassell (entomologist), John Krebs (birds), John Lawton (entomologist), A D McIntyre (marine invertebrates) and John Whittaker (entomologist); Journal of Applied Ecology jointly edited by entomologist, Tom Coaker and botanist R W Snaydon, had a slightly larger board, eleven in total, five botanists, two more entomologists, an invertebrate ecologist, an environmental physicist and two vertebrate ecologists. So for both these journals, vertebrate ecologists were in the minority.

Moving on to 2014, what is the current composition of the two boards? Journal of Animal Ecology, is dominated by vertebrate ecologists, 62%, with only 25% being invertebrate specialists. Journal of Applied Ecology is also dominated by vertebrate ecologists, 48%, with 28% being plant scientists of various hues and only 21% being invertebrate ecologists. Now let’s have a look at the two journals where there has been no change in the proportion of invertebrate papers published; Ecology is remarkably balanced, although invertebrates are under-represented; 27% plants, 27% vertebrates, 26% invertebrates, 9% microbial. Oikos has an even better board composition, 41% being invertebrate ecologists, 29% plant ecologist and a mere, although still over-represented, 17% being vertebrate ecologists.

In summary, although I am sure that there is no explicit bias against invertebrates by the Editors of either Journal of Animal Ecology or Journal of Applied Ecology, the very fact that their Editorial Boards are dominated by vertebrate ecologists acts as an attractant to vertebrate ecologists and as a deterrent to entomologists who thus choose to submit their papers elsewhere, resulting in the vertebrate dominated situation we see today.

Towards the end of Ken’s excellent post he says “Well, if the number of papers we published on each taxon reflected the number of species on the planet, then for every 1000 insect papers we publish, we should publish just 31 papers on fish, 13 on reptiles & amphibians, 10 on birds, and a miserly 5 papers on mammals! Clearly, this would be ridiculous”

Why would this be so ridiculous I ask? This is another good example of institutional vertebratism. After all, as Ken points out to us entomologists (and of course this includes Ken himself) “for taxon-specific papers, there are plenty of excellent specialist journals” This applies equally to the vertebrate world, so why shouldn’t a journal of animal ecology be dominated by invertebrates?
