Demonstrating and undergraduate projects

One of the big differences between being a PhD and an MSc student is that you are expected to contribute towards undergraduate teaching!  Most of the time this comes in the form of demonstrating.  This involves helping out in the practical classes and not necessarily teaching per se, but providing handy hints and generally acting as a problem-solver.  The enjoyment one gets from this very much depends on the particular course that you are demonstrating on! It's always much easier to demonstrate a subject that you know something about, for example.

At the other end of the spectrum is helping to supervise 3rd year projects.  I have found this much more enjoyable because you can follow the trajectory of the project from development to implementation and finally to completion.  It is even more rewarding when the project is 'useful' in the sense that it adds something to your own research.  I am lucky that my primary supervisors both try and pair undergraduates with PhD students who need something to be analysed or researched that is interesting but maybe not crucial to the central 'story' of their thesis.

So far I have had one student who was mainly supervised by Phil McGowan try to come up with a decision tree analysis framework that sought to determine which areas in SE Asia were priorities for re-surveying.  She did admirably well but annoyingly for me, there were no central Himalayan priority sites!  However, one major problem with her project that needs to be addressed is that it did not take into account habitat.  This meant that some of the supposed 'top' sites were not so 'top' after all.  Singapore is a good example: galliforms may have historically inhabited Singapore, but the only jungle that remains is definitely a concrete one!  This would explain why no-one has surveyed the site for galliforms in recent years and why in actuality, it is not a priority site at all.

This exemplifies brilliantly how an undergraduate project can contribute to wider research - it is not necessarily about finding out a definitive 'answer' but laying the groundwork and exploring some of the issues that myself and Phil McGowan would like to further focus on.  For example, I would very much like to repeat the decision tree analysis with habitat overlayed to see what effect this has on priority sites.  Additionally, I would like to repeat it but only for the greater Himalayas.  This all feeds into the final chapter I am hoping to write that will involve examining monitoring in the region.

I have recently had a new student come to work with me and this time the project will look at WWF ecoregions.  The idea is that these are ready-made (albeit irregular) grid cells that will allow us to examine which broad-scale habitat features are important for different galliform species.  At first though, I have suggested that we focus on how well the WPA records match what WWF says is true.  WWF uses data from BirdLife and it would be interesting to see if any further information alters the shape of their range maps.  Once we have examined all the pooled records (by time bin), we can start examining historical vs. recent records.  I have been creating lots of different graphs demonstrating how the data has different spatio-temporal biases, so the student can perhaps focus on some basic weighting systems that account for these biases.

Anyway, it should prove interesting and hopefully will give us a broad answer as to how useful the WWF ecoregions are as broad conservation tools for Himalayan galliforms!

Glasgow: black pudding, environmental statistics and rain...

Well, I have had a busy fortnight!  It started off with a week long course in environmental statistics that was held at the University of Glasgow.  The course is run by NERC to try and encourage people to use more sophisticated statistical concepts and to open people's eyes to what sort of tools are out there.  It was hosted by Professor Marian Scott, a sure case of nominative determinism if there ever was one.

We studied a variety of topics, including regression, time series, bayesian modelling, random effects models, spatial modelling, multivariate techniques, extremes and sampling design.  Given the broad nature of my own PhD, I found this wide selection very useful.  Understandably, it was impossible to cover every topic in much depth (you would probably need a whole week for each one!) but at least I have a better idea about some of the fundamentals and where to look for more information.  Plus, we were allowed to take away copies of R code, which should prove to be invaluable.

I particularly liked the Bayesian modelling course, as it seemed quite appropriate to some of the problems that I am encountering with my own historical data.  A lot of the museum specimens are 'presence only', which means that there is no information about what species they FAILED to find.  If we can use the idea of prior probabilities (a fundamental concept to Bayesian stats), we can incorporate expert opinion to give us a range of confidence as to whether we ought or ought not have found a certain species in a certain place in a certain period of time.

Statistics aside, Glasgow was actually rather different to my preconceptions: I imagined a very grim, rough city but was pleasantly surprised to find a modern, attractive and trendy urban space.  It even had its own underground system!  Unfortunately I found the accent more incomprehensible than even the Geordie one and felt that I stood out like a sore thumb, poncy southerner that I am.  Despite this, I wasn't the only southerner at the course and there were a wide range of people from all over the UK in attendance.  We all were put up in student accommodation in the very 'Harry Potterish' sounding 'Dobbie's Loan'.  I admit I have had a very sheltered upbringing as not only was this the first time that I had tried black pudding, but also the first time I had been to Scotland full stop!

I think that maybe I will go back to Scotland again but I definitely won't be eating black pudding any time soon....
Anyway, I've got lots of ideas and new things I want to investigate as a result of this course, so I had better get started!

Segment 1 of 9: Monitoring Tigers - Overview

Monitoring Tigers and their Prey video series

Matt Grainger (the new WPA Conservation Research and Support Officer) has forwarded me a series of YouTube videos that outline techniques for monitoring tigers and their prey.  The World Pheasant Association and their partners use many of the same techniques, so they're well worth watching.

If you're interested in learning more, check the rest of them out on YouTube!

Jon's study region
















This is the study region that I will be examining for my project.  The idea was to consult Dr Phil McGowan as to which WWF Ecoregions we felt were strictly 'Greater' Himalayan Ecoregions and not part of the Tibetan Plateau, for example.  This jpeg file is designed to give you an idea of the general size and scope of this project NOT detailed locality information.  As you can see, the Ecoregions intersect with the following countries: India, China, Pakistan, Nepal and Myanmar.  These will be the countries that I will focus on in my studies.

A little update on Jon's PhD activities


Hello Himalayan Galliformers!

Goodness! I can barely believe that it will soon be the best part of the year since the symposium in Thailand.  Although you wouldn’t know it, I have been busily working on my PhD project in the meantime.  I am the first to admit that communication has been a bit slack and it would nice to try and get more people sharing what they've been up to with the rest of the group (myself included!).  

It doesn’t have to be anything major – you can upload a summary of what work you’ve been doing recently or you can post questions to see if other members can help.  This can be done on the Yahoo group itself, or if you have a blog you can link it to the Yahoo group as well.  

In order to get the ball rolling, here are some of the things that I have been working on in my own project:
  • Managing the database, accumulating information on Himalayan species and countries and examining and exploring the data
  • Creating subsets of data separated by quality and quantity
  • Writing a general introduction to my PhD
  • Learning ArcGIS skills and creating shapefiles from locality data
  • Reading up on occupancy studies and techniques for dealing with bias in historical data
  • Working on Lowell Mill’s SPR model with Dr Pete Garson
  • Working with a 3rd year undergraduate to help identify priority localities for re-surveying across South East Asia
All in all, it’s been quite a busy period!  Part of the learning process has been deciding which direction my project will take.  Ultimately, I have decided that I will NOT be doing any social survey fieldwork in India and rather, the main thrust of this project will be to focus on regional scale conservation of the Himalayas solely using GIS and modelling approaches and many of the suggestions in the workshop in Thailand were taken into account.   

The priority for me at the moment is ensuring that my methods for dealing with bias in historical data are robust.  As it is such a crucial part of the project, I have been concentrating on that particular aspect quite thoroughly.

One of the other things that I am working on at the moment is trying to collate information on nationwide monitoring schemes and information on wildlife policies/legislation in each of the respective Himalayan countries.  Therefore, could I politely request that if anyone knows of any resources (organisations/people to contact) that they get in contact, please?

On the subject of requesting information, I recognise that it could be that some people need access to papers but do not have a subscription to certain journals.  If this is the case, Laura Owens, and I are willing to post the pdf files on the Yahoo site, if people let us know what papers they are trying to access.   

We will try and be as helpful as possible! Other things that we can offer help with include proof-reading English manuscripts if required (Matt Grainger will probably be able to help with this too).

Finally, if you have any new information or species distribution data, we invite you to send it to Laura Owens who will enter it onto the WPA central repository.
Anyway, best wishes to everyone out there and I hope all your research is going well!  If anyone would like to post anything on the Yahoo group site, please feel free to do so!
