Someone (**cough** **cough** Morgan) fell down on their job rebloging the Portal Project 40th anniversary posts to Jabberwocky. But that means this week is the week o’ Portal as we reblog the various posts from the past few weeks. First up, what happens when we go out in the summer to count plants?
Twice a year the Portal crew gets a little larger, and spends a few extra days, and we count plants on all 384 quadrats. Despite some of us being in our second decade of visiting the site, and everyone on the plant crew being intimately familiar with most of the species at the site, and that the rodent RA has been watching the plants grow and giving us monthly updates, we still never really know what we’re going to find once we get out there. The desert does what it wants.
The uncertainty seems especially high for the summer plant community. Some years we arrive to an ocean of grass, waving in the breeze. Those are the years we spend a lot of ‘quality time’ with each quadrat. Other years we arrive to a dustbowl. We walk around the site laying our PVC quadrat down and picking it back up…

The latest installment from the Portal Project Blog on the watch for Banner-tailed Kangaroo Rats
Much beloved by those who have worked at the Portal Project, the banner-tailed kangaroo rat (Dipodomys spectabilis) is one of the most charismatic rodents at the site (for us smammal lovers who think rodents can be charismatic, anyway). The fact that they have a nickname—spectabs—attests to this fondness. Look at that mighty tufted tail! Those giant, majestic furred feet! Weighing in at over 100 grams as adults, they are twice the size of our other kangaroo rat species (D. ordii and D. merriami). What’s not to love?
As avid readers of the Portal blog might recall, the site used to be much grassier back in the day. At the start of the project in 1977, spectabs were running the show at Portal; we even had some plots that excluded only D. spectabilis because they were so dominant! For the spectabs, this was a desert…

How did we get those daily pics of the desert turning green in a week? Meet Portal’s new toy: the Phenocam.
For starters, it allows us to do things like watch our desert field site turn from brown to green in no time flat (and back to brown again this winter).
But even cooler, our camera is part of the PhenoCam Network. They’re organizing a network of near-surface remote sensing images from sites all over the world. This creates a time series of images, in RGB and infrared, that can be used for phenology monitoring by the PhenoCam folks, us, or anyone who’s interested.
The PhenoCam folks make all the imagery freely available to download. From installation and configuration to image analysis, they provide awesome support. And their R package phenopix provides a quickstart to using phenocam imagery.
A guest post from last week on the Portal Blog about studying Kangaroo rat placentas!
~While everyone’s busy at ESA this week, we’d like to keep the 40th anniversary ball rolling with a guest post from a visiting researcher at Portal. Jess Dudley has been using the Portal area to compare pregnancy in kangaroo rats and Australian marsupials. We’ll be featuring other guest posts through the rest of the year. (If you’d like to do something similar, please send us your info!)~
In July 2015 I travelled the 24+ hours from Sydney, Australia to the beautiful town of Portal to research pregnancy in Kangaroo rats. To everyone’s astonishment we do not have Kangaroo rats in Australia! I am sure I don’t need to explain my fascination with Kangaroo rats with this audience but in terms of pregnancy they have some unique features which differ from most rodents. This finding by King and Tibbitts in the 1960’s led me to wonder how the placenta forms during pregnancy…

We’re really looking forward to catching up with old friends and meeting new people this week.
Should you cite preprints in your papers and should journals allow this? This is a topic that gets debated periodically. The most recent round of Twitter debate started last week when Martin Hunt pointed out that the journal Nucleic Acids Research wouldn’t allow him to cite them. A couple of days later I suggested that journals that don’t allow citing preprints are putting their authors’ at risk by forcing them not to cite relevant work. Roughly forty games of Sleeping Queens later (my kid is really into Sleeping Queens) I reopened Twitter and found a roiling debate over whether citing preprints was appropriate at all.
The basic argument against citing preprints is that they aren’t peer reviewed. E.g.,
and that this could lead to the citation of bad work and the potential decay of science. E.g.,
There are three reasons I disagree with this argument:
- We already cite lots of non-peer reviewed things in ecology
- Lots of fields already do this and they are doing just fine.
- Responsibility for the citation lies with the citer
We already cite non-peer reviewed things in ecology
As Auriel Fournier, Stephen Heard, Michael Hoffman, TerryMcGlynn and ATMoody pointed out we already cite lots of things that aren’t peer reviewed including government agency reports, white papers, and other “grey literature”.
We also cite lots of other really important non-peer reviewed things like data and software. We been doing this for decades. Ecology hasn’t become polluted with pseudo science. It will all be OK.
Lots of other fields already do this
One of the things I find amusing/exhausting about biologists debating preprints is ignorance of their history and use in other fields. It’s a bit like debating the name of an actor for two hours when you could easily look it up on Google.
In this particular case (as Eric Pedersen pointed out) we know that citation of preprints isn’t going to cause problems for the field because it hasn’t caused issues in other fields and has almost invariably become standard practice in fields that use preprints. Unless you think Physics and Math are having real issues it’s difficult to argue that this is a meaningful problem. Just ask a physicist
You are responsible for your citations
Why hasn’t citing unreviewed work caused the wheels to fall off of science? Because citing appropriate work in the proper context is part of our job. There are good preprints and bad preprints, good reports and bad reports, good data and bad data, good software and bad software, and good papers and bad papers. As Belinda Phipson, Casey Green, Dave Harris and Sebastian Raschka point out it is up to us as the people citing research to make professional judgments about what is good science and should be cited. Casey’s take captures my thoughts on this exactly:
So yes, you should cite preprints and other unreviewed things that are important for your work. That’s called proper attribution. It has worked in ecology and other fields for decades. It will continue to work because we are scientists and evaluating the science we cite is part of our jobs. You can even cite this blog post if you want to.
Thanks to everyone both linked here and not for the spirited discussion. Sorry I wasn’t there, but Sleeping Queens is a pretty awesome game.
UPDATE: For those of you new to this discussion, it’s been going on for a long time even in biology. Here is Graham Coop’s excellent post from nearly 4 years ago.
UPDATE: Discussion of why it’s important to put preprint citations are in the reference list
The Weecology lab group run by Ethan White and Morgan Ernest at the University of Florida is seeking a Data Analyst to work collaboratively with faculty, graduate students, and postdocs to understand and model ecological systems.

We are very exited to announce a major new release of the Data Retriever, our software for making it quick and easy to get clean, ready to analyze, versions of publicly available data.
The Data Retriever, automates the downloading, cleaning, and installing of ecological and environmental data into your choice of databases and flat file formats. Instead of hours tracking down the data on the web, downloading it, trying to import it, running into issues (e.g, non-standard nulls, problematic column names, encoding issues), fixing one problem, and then encountering the next, all you need to do is run a single command from the command line:
$ retriever install csv iris $ retriever install sqlite breed-bird-survey -f bbs.sqlite
or from R:
>>> rdataretriever::install('postgres', 'wine-quality') >>> portal_data <- rdataretriever::fetch('portal')
The Data Retriever uses information in Frictionless Data datapackage.json files to automatically handle all of the complexities of “simple” data for you. For more complicated complicated datasets, with dozens of components or major data structure issues, the Retriever uses Python scripts as plugins to handle the major data cleaning work and then automatically handles the rest.
Expanded focus and name change
For those of you familiar with the EcoData Retriever, this is the same software with a new name. Challenges with the data end of the analysis pipeline occur across disciplines and our tools work just as well for non-ecological data, so we’ve started adding non-ecological data and changed our name to reflect that. We’d love to hear from anyone interested in leading a push to add data from another discipline or just interested in adding a single favorite dataset.
As part of this we’ve changed the name of the R package from
The 2.0 release includes a number of major changes including:
- Python 3 support (a single code base runs on both Python 2 and 3)
- Adoption of the frictionless data datapackage.json standard (replacing our old YAML like metadata system), including a command line interface for creating and editing datapackage.json files
- Add json and xml as available output formats
- Major expansion of the documentation and hosting of the documentation at Read the Docs
- Remove the graphical user interface (to allow us to focus that development time on wrappers for other languages)
- Lots of work under the hood and major improvements in testing
- Broaden scope to include non-ecological data
We are also in the process of releasing version 1.0 of the R package. This version adds the new features in the Data Retriever and also includes major stability improvements, in particular in RStudio and on Windows.
We also have a brand new website.
Upgrading to the new version (UPDATED)
To ensure the smoothest upgrade to the new version we recommend:
retriever reset scriptsfrom the command line
- Uninstall the old version of the EcoData Retriever
- Install the new version
retriever updatefrom the command line
Henry Senyondo is the lead developer for the Data Retriever and has done an amazing job over the past year developing new features and shoring up the fundamentals for the software. He lead the work on 2.0 start to finish.
Akash Goel was a Google Summer of Code student with the project last summer and was responsible for the majority of the work adding Python 3 support and switching the project over to the
Dan McGlinn, the creator of the R package, has continued his excellent leadership of the development of this package. Shawn Taylor, a new contributor, was instrumental in solving the stability issues on Windows/RStudio.
In addition to these core folks our growing group of contributors to both projects have been invaluable for adding new functionality, fixing bugs, and testing new changes. We are super excited to have contributions from 30 different people and will keep working hard to make sure that everyone feels welcome and supported in contributing to the project.
The level of work done to get these releases out the door was only possible due to generous support of the Gordon and Betty Moore Foundation’s Data Driven Discovery Initiative. This support allowed my group to employ Henry as a full time software engineer to work on these and other projects. This kind of active support for the development and maintenance of research oriented software makes sustainable software development at universities possible.
