Taking a short trip to the American southwest, I have discovered my study shrub occurs quite commonly. Although I normally examine Ephedra californica in the Mojave and San Joaquin deserts in my travels, I have found it i the Chihuahuan Desert, Sonoran Desert, Great Basin Desert, and Colorado Plateau.
9 lucky blunted-nosed leopard lizards are enjoying their new necklaces.
Hoping to catch more lizards soon. Our goal is to have 12-15 animals collared by the end of the week.
Chase and I have been spending lots of time with our new friends. We relocated the lizards several times a week, as well as doing hour-long behavior observations. By the end of the season we hope to have 4-5 hours of observation on each animal.
A two day work session at UCSB was extremely informative covering a wide range of topics for programming and ecology. The course was divided into four components: bash-cmd, intro to R-studio, Github, and data manipulation in R-studio. I especially liked how the course took a more abstract approach without going through statistics. Rather it was focused on data manipulation for the day to day ecologist. One of the more unexpected things I learned from the process was R-markdown and developing websites using it with Github. All of these tools can significantly help with collaboration. Although most of what I had been doing in R is not wrong, it may be difficult for a collaborator to pick up my code and start using it. I think this course really helps me bridge that gap and it is something I am going to push forward on. Gone are the days of sharing Word Documents with 6 versions of the same figure.
All the course materials are found on the website here! I would recommend anyone even slightly interested in the above topics to go through it. Below are some highlighted parts that I believe deserve a little extra attention.
One thing that was lightly talked about within the short 3 hour time frame we had, is the power of Bash Shell. Bash Shell (cmd) is Neo from the matrix. All the rules are off and boundaries are endless. It has happened to me before on simple tasks that files or hard drives will be written off as corrupt, yet all the files are still there. Bash Shell has allowed me to see what my OS restricts. This unrestricted access and combination for programming can allow tasks to be committed that otherwise are not possible in real-time or at all. To bring in another movie reference, “with great power comes great responsibility”. Despite the overwhelming power of Bash Shell, it is easy to do things wrong… very wrong. It that way it may be intimidated to users because there is no undo or recycling bin. Still, a very powerful tool for the ecologist who wants to do something on their computer, but can’t.
Base vs Dplyr
Why is Dplyr better than Base? I haven’t quite found out if Dplyr better, but I have noticed that it is easier to understand when sharing with collaborators. Nesting functions within funtions may make sense to you, but to others it can look like a disaster. Will I switch over to dplyr? Maybe. It does mean learning a bunch more commands and most are the same character length as base. However, collaboration is everything and seeing subset(subset(subset… may scare a few people off.
Such an unexpected surprised! I really like Rmarkdown and how easy it is to generate a quality website with little code. The best part is that it still has easy functionality to link to CSS or HTML files. Nothing is perfect, and it unfortunately means learning another series of commands and codes for something that already exist. However, it does tie in better with R scripting. This allows for the development of half-websites, half-experiment results that can be used as a blog post, shared with others, etc. The course taught us a lot about it and I’m already forgetting much of what I heard, but I will begin to incorporate as much as I can.
As the plant field season comes to a close, the lizard field season kicks off. Here are some picture highlights.
I have a new paper out in advance access at The Journal of Plant Ecology. The link at the bottom provides you free access to the paper before it has been typeset and proofed

Although this season has been wetter than last year, it is not quite the big El Nino event that was expected. Nonetheless there has been something of a superbloom for the Panoche Hills which is typically dominated by invasive Mediterranean annual grasses.
This year, this bloom was especially apparent along the access road with Monolopia, Phacelia and Amsinckia dominating with a few lupines
We have had a great deal of success with our experimental plots up at the plateau area too!
There are tons of flowers it the valleys and slopes within the hills too
Although things are starting to seed and brown up here, there are still some remnants of flowers on north facing slopes
unlike the very green hills we observed earlier in the year
We would like to advertise our ESA workshop: How to Set Up Automated Sensors Arrays for Measuring Micro-Environmental Characteristics and Synthesize to Larger Scales
Abstract: Tracking the consequences of environmental change requires information on both the physical and biological characteristics of ecological systems. Large-scale environmental data are now widely available from many data repositories. However, these data sets often need to be down-scaled in order to be paired with local ecological measurements. Hence, micro-environmental sensors are sometimes useful to integrate scales of ecological information relevant to global change. In this workshop, we will demonstrate the use of all major affordable types of micro-environmental sensors available to collect fine-scale environmental data. Using the R environment, we will also provide the means to analyze these data and also to integrate this information with ecological data and macro-environmental data streams. The overall purpose of this workshop is to provide attendees with hands on experience on the use of automated sensors of micro-environmental variables, their appropriate deployment in the field in relation to ecological questions, and an introduction to the integration of micro-scale data to larger environmental datasets. This workshop will also serve to launch MicroNet. This is an open-source, collaborative network of micro-environmental sensors deployed globally.
And this is the link to the ESA Programme: https://eco.confex.com/eco/2016/webprogram/Session11870.html
The workshop will take place on Monday August 12 at room 304 of the Fort Lauderdale Convention Center, between 11:30am and 1:15 pm.
We hope to see you there!
