Reference Barcode Sequences

All interns this year succeeded in generating at least one reference barcode sequence, registered at the international genetic barcode reference library Barcode of Life Database (BOLD).

The links here lead to the full reference records, including specimen information, photographs, sequences, and sequencing tracefiles.

NOTE: because it takes BOLD a few weeks to make “public” records public, the links below may not work until sometime in August 2019.

First Week Online Activities

During this first, online week of the ARIP program, we have two goals. One is to familiarize you with reading real research papers: the scientific literature. The other goal is to familiarize you with some of the genetic biodiversity concepts you’ll be working with during the on-site two weeks of the internship.

Understanding the content of these papers is very important for doing well in the internship. You will be expected to know these concepts and be able to work with them once you are here. We know they are complex ideas, and we know that learning them directly from the actual research literature (not popular articles) is difficult. But that’s why you are participating in this internship. You will work hard. In return, we will work hard to give you all the help and information you need to do well — that is why we are participating.

The way this will work is that there will be a series of daily reading assignments. Each day you will be required to complete a brief quiz about the reading for that day. That quiz will be available for only 24 hours — you must check in here and complete the quiz sometime during the 24 hour window for that day’s reading.

To be completely open with you: the purpose of those quizzes is not to grade or rank your performance, but to ensure that you do some of the reading each day. If you could leave it all to one session at the end, there is no way you could get good comprehension!

The materials are available to you now (see links lower on this page), so feel free to read ahead! But, again, you will have to return to this web page each day to complete each day’s questions on the assigned day.

What if I have questions about the material or the assignment?
Feel free to send email with questions to me (Dean Pentcheff). I’m managing the online portion of the course (I’ll also be participating in leading the on-site part). You can reach me at: .

What if I will be unavailable or travelling on one or more of the assignment days?
Send me an email (to and I’ll get the day’s questions to you by email so that you can complete them on a different day.

What time of day will the day’s questions become available (and when will they disappear)?
Each day’s questions will become available at 00:01 (one minute into the day) on the day of the assignment, and will close at 23:59 (one minute before midnight) on the day of the assignment. All dates and times will be in Pacific Daylight Time (PDT UTC-7).

Online Day 1 (Monday) July 8 — Reading a scientific paper

We‘re starting easily. Today there are two online articles we‘d like you to read that will help you learn how to (constructively) read a scientific paper.

Reading 1: How to read a scientific paper

Reading 2: How to read and understand a scientific paper: a guide for non-scientists

Read both of these to prepare yourself for reading the scientific papers over the next few days. These guides refer to two kinds of scientific papers: primary research papers and review papers. Most of the papers we‘ll have you read are review papers — they summarize the work reported in many other papers. Because of that, they will not be broken into the structure of a typical primary research paper (Introduction, Materials and Methods, Results, and Discussion). However, the analysis you will need to do as you read (for example, looking up every single word you don‘t understand as you read) is the same for primary and review papers.

This quiz is now closed.

So that everyone can catch up, we will leave this first day’s quiz open for two days.

Online Day 2 (Tuesday) July 9 — Genetic barcoding

“Genetic barcoding” is a technique being applied to biodiversity research, and is a core technology you will use and learn in this internship. These two papers give a bit of perspective on the technique. The first was written over a decade ago as barcoding was just being developed. The second looks back over the decade of development and summarizes how the field has grown.

Reading 1: Savolainen, V., R. S. Cowan, A. P. Vogler, G. K. Roderick, and R. Lane. 2005. Towards writing the encyclopaedia of life: an introduction to DNA barcoding. Philosophical Transactions of the Royal Society B: Biological Sciences 360:1805–1811.

Reading 2: Hebert, P. D. N., P. M. Hollingsworth, and M. Hajibabaei. 2016. From writing to reading the encyclopedia of life. Philosophical Transactions of the Royal Society B: Biological Sciences 371:20150321.

This quiz is now closed.

Online Day 3 (Wednesday) July 10 — Metabarcoding entire communities

One of the really exiting ways we can use genetic barcodes is to describe entire marine communities based just on seawater samples (by sequencing and identifying the DNA that organisms shed into the seawater). This paper is a recent example of that kind of work. (Note that this is a primary research paper, a report of novel work, unlike the rest of the papers we are having you read, which are review papers.)

Reading: Kelly, R. P., J. L. O’Donnell, N. C. Lowell, A. O. Shelton, J. F. Samhouri, S. M. Hennessey, B. E. Feist, and G. D. Williams. 2016. Genetic signatures of ecological diversity along an urbanization gradient. PeerJ 4:e2444.

This quiz is now closed.

I apologize for messing up the availability of the Day 3 quiz! That was entirely a technical error on my part, and was not your fault at all. To make sure you get a chance to answer the questions, I will leave this quiz open all day on Thursday (as well as Thursday’s quiz). Again — I apologize for the mistake! [Dean Pentcheff]

Online Day 4 (Thursday) July 11 — Barcoding and biomonitoring

A key application of barcoding, particularly of entire communities, is the potential it has for letting us monitor biological changes more frequently, more cheaply, and in more detail than traditional techniques.

Reading: Thomsen, P. F., and E. Willerslev. 2015. Environmental DNA — An emerging tool in conservation for monitoring past and present biodiversity. Biological Conservation 183:4–18.

This quiz is now closed.

Online Day 5 (Friday) July 12 — DNA extraction and taxonomy

For the first reading, we are jumping directly into some of the work you will do in the internship. In a theoretical way, you have read about DNA extractions for making genetic reference barcode sequences. A key step along the way is extraction and purification of DNA from your organism of choice. This first paper is the extraction protocol that you will be following in the lab. It is the protocol for using the popular “DNeasy Blood & Tissue” extraction kit. You will actually be carrying out this procedure, so read this carefully. You remember the Day 1 readings on how to read a scientific paper? Treat this like the Materials & Methods section of a research paper: look up the meaning of words you don’t understand; draw yourself diagrams of what actions are being described.

The science of taxonomy is the discipline of classifying organisms into some sort of understandable system. It has taken us a couple of centuries to name and describe about one million species. We think there are something like 10–100 million species on earth. Clearly, we have a lot of work to do. The second of these papers gives a little perspective on how genetic barcoding may help us — part of the reason we have initiated our whole research program here at the Natural History Museum.

Thanks for participating in the online week! We will see you soon in Los Angeles.
