In response to Caroline’s request for more locations to plant Stipa in the common garden, I have selected 208 new locations at random. This map shows the new locations in green. (Blue dots are the previously selected locations.) Here’s a file listing all 208 location. It’s suitable for making 208 labels for 208 seeds! stipaSeedLabels2.csv 2 graphs that are basically the same as the one with alfalfa on my poster, bu tusing sweet clover and amorpha instead. Although amorpha is the most common native species in floral neighborhoods per unique plant, there are only 43 plants that had either just amorpha, just echinacea, both , or neither. For sweet clover, the sample size is 82, but the graph isn’t very impressive either…. Do you think either one is usable? I originally wanted to use the most common native and the most common exotic (alfalfa and amorpha). Hey yall, Final version of poster: Jenkins REU09.pdf Hope everyone’s doing well in K-town! I miss yall already…and my bike 🙁 ps. I knew Roxy would come through for us. Warren should’ve known better after the snake incident. August looks like it will be my busiest month this summer. I’m currently working on four species, and will expect to start two more before the end of the month. Here’s the status of my species so far. Pediomelum esculentum- I have collected fruit from all of my experimental plants. I have not started to count seed yet. Dichanthelium oligosanthes- I have finished collecting fruit and am in the process of counting seed. From what I’ve seen so far, D. oligosanthes is SC, although I can’t rule out agamospermy. Asclepias viridiflora- These plants are also in fruit. Of my selfed flowers, only one has remained on the peduncle. I doubt it will turn into a fruit, which could mean one of two things: A. viridiflora is SI, or I’m not qualified to be an Asclepias pollinator. Potentilla arguta- My plants have finished flowering and are in fruit. I’m waiting for them to mature so I can start collecting. Panicum capillare- I have about twelve inflorescences bagged and am trying to get the “styles on agar” method to work. Cirsium altissimum- There are lots of plants and will be over a hundred heads to work with out at Hegg Lake. At this point none have flowered yet, but I have them all flagged, twist-tied, and ready to go. Potentilla pensylvanica- I have been pollinating these at Glacial Lakes State Park for a few days now. They don’t flower a lot and they are nearing the end of flowering, but I believe I will manage to get enough pollinated before they finish. Either way, Glacial Lakes is a beautiful place to be doing field work! Teucrium canadense- While checking out some Carex yesterday I discovered Teucrium growing at the back hill. There were enough plants to work with and not yet done flowering, so I flagged and bagged today. Tomorrow I will begin pollinations. I also expect to be working with at least Muhlenbergia cuspidata and Solidago speciosa before the summer ends. I’m about half-way through scanning Stipa seeds and organizing them for planting, and may have underestimated how many we have! I thought we’d have approximately 6 seeds per maternal plant and, if we collected from 400 maternal plants in the field, that’s 2400 seeds. Stuart picked ~2600 positions to plant in. Plenty, right? Well, after assigning positions to seeds from 208 plants, I have 214 to go. That means I underestimated the number of plants we collected from. Also, we’re averaging more like 6.4 seeds per maternal plant. Another underestimation. I think we need another 200 positions to comfortably assign all seeds to their new homes the garden. What do you think? |
