Yet another post about gender and academic conferences

genderThis is becoming something of a cottage industry recently – it is fairly straightforward to calculate the gender ratio of presenters at academic conferences and to evaluate that ratio against some theoretical baseline. However, these sorts of questions are important to look at because the work is highly complex and so requires a large number of people looking at the diverse kinds of conferences to provide a bigger picture. A number of previous studies have shown a range of different patterns in gender and academic conferences (references at the bottom): Continue reading

Historical changes in the phenology of British Odonata are related to climate [paper summary]

This is part of a series of short lay summaries that describe the technical publications I have authored. This paper, entitled “Historical changes in the phenology of British Odonata are related to climate”, was published in the journal Global Change Biology in 2007 (my first paper!). You can find this paper online at the publisher, or on Figshare.

Background: A variety of responses to climate change have been detected in a variety of taxa.  Among these is a change in phenology – the timing of the life cycle (like the emergence of an adult dragonfly from its larval case as shown on the right). Since some species use temperature as a cue for when to develop, as the environment warms there is a signal of earlier development in these species. Continue reading

Who would win in a fight between a rhino and a tiger?

tigerrhinoI got an email from our university press officer earlier this week asking “whether we have a ‘zoologist who could participate in a light-hearted discussion about who would win in a fight between a tiger and a rhino on Friday morning’.” The request was from the local BBC Radio Leeds team who wanted to break up their coverage of the Leeds Rhinos vs Castleford Tigers rugby league Challenge Cup final preparations with some light-hearted digressions. I have resolved to take a more active part in science communication (including this blog), because I see that as a fundamental part of my job (even if it is little-rewarded…) and so I agreed to do it.

Why I blog (occasionally!)

There has been a lot of discussion over the merits of academics blogging (see here, here, here, here, here and here). The positive arguments seem to be that:

  1. It’s good outreach, allowing a flexible platform for communication of science
  2. Blogs allow rapid responses and reporting on research
  3. Online profiles are important and blogs can be a strong foothold in internet-space
  4. Writing for a non-technical audience is good practice for science communication

The negative arguments seem to be that:

  1. It doesn’t count in academic terms (it’s not a paper, a grant, or a lecture)
  2. Sometimes tenure panels might see blogging as a waste of time
  3. There’s the danger of “upsetting” people.

Well I think it counts (even if my colleagues disagree), we don’t have tenure in the UK, and I don’t mind upsetting people, so there’s no good reason for me not to blog! I was letting it drop off a bit, but all this discussion has encouraged me to start up again. One of the problems is that I lacked a blogging strategy, which meant that I only shared what I (A) found interesting, and (B) found time to write about. Most of my problem was that I found interesting topics and spent too much time on too few, too niche issues. That’s going to change. Here’s the plan:

  • I’m going to post lay summaries of each of my publications.  That’s 25 to start with, and I’ll add more as I go along. I see that as a vital part of science communication, and I’ll link them back to my publications page on my website.
  • I have recently been immersing myself in Twitter which has led to my discovering a lot more interesting (and sometimes plain weird) papers and articles. This will be a key (near-bottomless) source for new ideas, but I’ll try to keep to a theme.
  • The main topicsare going to be
    • General science things
    • Entomology news and views
    • Education and technology
    • Specific posts about my research
  • Finally, I’m going to write in short form now – no more monthly long reads. 500 words max, and always with an image or video. It was the length and detail that was killing my productivity, and nobody reads those longreads, anyway!

I am hoping that that is going to provide a sustainable flow of content over the next few months, and I’ll reevaluate at Christmas.  Happy reading!

Study design and mark recapture estimates of dispersal [paper summary]

This is part of a series of short lay summaries that describe the technical publications I have authored.  This paper, entitled “Study design and mark recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale”, was published in the Journal of Insect Conservation in 2012. You can find this paper online at the publisher, or on Figshare.

9303167014_cdbcb32d61_zBackground:  I have long been interested by movement of animals in the landscape and whether or not this can be accurately quantified in the field.  One of the major issues associated with these field studies (such as mark-release-recapture studies, in which animals are marked with a unique tag then recaptured at a later time) is that you cannot detect dispersal distances that are greater than the size of the study area that you are using.  For example, people have been marking damselflies for decades to try to measure how far they fly.  However, if you only look for them 500m from where you first found them, you won’t find them flying any further than that.

What we did: This study used a large mark-release-recapture dataset and investigated the effect that expanding a study area has on the maximum dispersal distance detected.  We found that the original study (on the endangered southern damselfly, Coenagrion mercuriale) was at a scale sufficient to estimate the maximum distance that the insect is able to fly, around 2km.

Importance: This endangered species has very specific habitat requirements (water meadows and shallow ditch systems) which mean that it has a long distance to move between these rare areas.

My first preprint submission

My last post was about open access – making sure that your work is freely available after publication. However, I have also been experimenting with preprints – posting articles prior to publication for open peer review. PeerJ is one publishing model that has been gaining traction recently. They also offered free publication for a trial window and have a monkey as their mascot, so how could I resist? My paper, “Continental variation in wing pigmentation in Calopteryx damselflies is related to the presence of heterospecifics” is available now (with all the data used in the paper) at the PeerJ preprint site, while the manuscript is in review at the PeerJ journal. I thought it worthwhile reflecting on the experience and my growing support for this idea. Continue reading

Be sensible about open access, but it’s still a good thing!

In a recent paper published in Trends in Plant Science, Anurag Angrawal presents a few “reasons to be skeptical of open-access publishing” (Angarwal, 2014) in order to stimulate debate over the current open access (OA) publishing model. Ironically this is behind a paywall so I thought I would summarise the content, which is more reasonable than the title suggests. Here is the gist of the four problems: Continue reading
