Lockdown still, but collaborators at local site that manage research reserve kindly agreed to collect native seeds.
As a team, we are discussing the fine-scale grain of sampling for estimating annual-annual plant interactions in deserts. We are particularly interested in the Mojave Desert to examine pollinator-herbivore interactions with annuals that are mediated by the other immediately adjacent congeneric species. Here is a brief compilation of key papers examining this challenge.

I am a fan of the 15cm scale for fine-scale but often sample with a 15cm ring nested within a second 30cm metal ring. I construct using wire.

In collaboration with Professor Katie O’Meara, an architect, Professor Zaitchik, an Earth Scientist, and researcher Claire Moriarty, we are examining the use of drones to map keystone species in extreme environments such as cushion plants in Patagonia or shrubs in deserts. This is just a pilot experiment (haha, get it), and we need a graduate student for 2020 to dig in and ground-truth the metrics we will derive from imagery. The focus will be structure and architecture in natural systems.
York Science Fellow Dr. Jacob Lucero and international collaborator Dr Merav Seifan are launching into 2020 with an ambitious experiment in Israel and California. The purpose is to explore the relative importance of provenance of a highly invasive species of bromus in the deserts of California by comparing performance and key interactions in its home range, Israel, and in its introduced range, California. This is a new direction from previous work published in NeoBiota entitled ‘The dark side of facilitation: native shrubs facilitate exotic annuals more strongly than native annuals’ that demonstrated a very significant effect of bromus on local plant community dynamics.
Sometimes, peer review (and procrastination) help. Other times, the delays generate more net work. I was discussing this workflow with a colleague regarding a paper that was submitted two-years ago, rejected, then we both ran out of steam. This was the gold-standard workflow we proposed (versus reformat and submit to another journal immediately).
- Hit web of science and check for new papers on topic.
- Download the pdfs.
- Read them.
- Think about what to cite or add.
- Add citations and rebuild biblio.
- Update writing to mention new citations especially if they are really relevant (intro and discussion).
- Take whatever pearls of wisdom you can from rejection in first place and revise ideas, plots, or stats.
- Format for new journal.
- Check requirements for that journal.
- Search the table of contents for the journal and check your lit cited to ensure you cite a few papers from that journal – if not, assess whether that the right journal for this contribution.
- Download pdfs from new journal, read, cite, and interpret.
- Then, look up referees and emails.
- Write cover letter.
- Set up account for that new and different annoying journal system – register and wait.
- Fight with system to submit and complete all the little boxes/fields.
No markers go a long way to better meetings!

I had a great time last week representing the Lortie lab and discussing work from my research practicum with president and vice chancellor of York university Rhonda Lenton. Aside from gaining wonderful feedback from her, which will definitely assist me in my future endeavours, I was thrilled to present the importance and impact of biology research with her as well as the many other influential attendees. I am excited and eager to experience the opportunities that lie ahead.
