Quaint titles and memorable lines in ecology and entomology

I am always struck when reading the old entomological and ecological literature by how much the style of our writing has changed over the last 100 years or so, and not necessarily for the better 😉 I am not advocating a return to the writing style of the Victorian 3-volume novel but do think that we might try to be a bit less dry when reporting our science in mainstream journals. With the establishment of on-line publishing perhaps there will be less emphasis on word limits from Editors and publishers, but then on the other hand, we are all busy people and the number of papers published seems to be increasing at an exponential rate.

Here for your edification is a title from the mid-Victorian period; penned by John Curtis an English entomologist

Curtis, J. (1845) Observations on the natural history and economy of various insects etc., affecting the corn-crops, including the parasitic enemies of the wheat midge, the thrips, wheat louse, wheat bug and also the little worm called Vibrio. Journal of the Royal Agricultural Society, 6, 493-518.

There are also some great sentences in this paper that give you an insight into the character of the man and the conditions under which he worked, which we do not get in modern papers.

“I had hoped, during the past summer, to make some progress in the further development of the economy of the Wheat-midge; but although the little orange larvae were abundant in some wheat-fields in August in this neighbourhood, owing to the wet and cold season I presume, I did not discover a single midge on the wing, and the larvae appear to have all died as usual”

Later on writing about aphids; I couldn’t possibly not mention aphids 😉

“The corn-crops do not escape the visitations of this extensive tribe: indeed, what crop does?”

 

And from that great entomologist A R Wallace writing in 1865 on species distribution, Wallace, A.R. (1855) On the law which has regulated the introduction of new species. Journal of Natural History, 16, 184-196.

“Fully to enter into such a subject would occupy much space, and it is only in consequence of some views having been lately promulgated, he believes in a wrong direction, that he now ventures to present his ideas to the public, with only such obvious illustrations of the arguments and results as occur to him in a place far removed from all means of reference and exact information”

Obviously a man of great probity and conviction.

 

We all know of Darwin’s story, (Darwin, 1929), about having to put a beetle into his mouth having gone collecting beetles without suitable containers but how many of us know about this side of his character, also from the same source,

“A novel, according to my taste, does not come into the first class unless it contains some person whom one can thoroughly love, and if a pretty woman all the better”

It is a great little book and well worth reading.

Darwin, F. (1929) Autobiography of Charles Darwin, Watts & Co., London

 

Norman McIndoo, the inventor of the insect olfactometer writes in his 1926 paper, McIndoo, N.E. (1926) An insect olfactometer. Journal of Economic Entomology, 19, 545-571

“To the writer a potato plant has a characteristic smell, although not as strong as those from some other plants. When enclosed in the plant chamber, its odors are perhaps emanated along with the water vapour, which judged from the condensed portion, was considerable.”

 

And here in a relatively modern paper, from that intrepid entomologist Philip Darlington, P.J. (1970) Carabidae on tropical islands, especially the West Indies. Biotropica, 2, 7-15

“Mr Hlvac’s (1969) paper should be consulted for further details and discussion. But a very great deal still remains to be done on Scarites in Puerto Rico. Here obviously is another opportunity for exciting ecologic work, to be done under exceptional circumstances of comfort and convenience”

Non-entomologists will no doubt be familiar with Darlington from his classic species-area work on Caribbean herpetofauna.

 

So dear readers, which are your favourite memorable sentences and titles from the scientific literature?  Please let me know.

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 blog “These 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?
