Unit 05: Summer Science Reflections š¼
Hey fellow interpreters! I donāt know about all of you, but the last couple of weeks have been super busy. Between school, work, extracurriculars, and maintaining a healthy social life,Ā Overwhelming OctoberĀ seems to have snuck up on me (yet again). During this time, fostering my relationship with nature is moreĀ crucialĀ than ever. My coursework and extracurriculars are highly environment-focused (which definitely helps), but itās the time spent in nature for no āproductiveā purpose that truly maintains my motivation and mental healthā lots of laying in the grass, digging around for insects, and sporophyte observing during my seemingly limited spare time.Ā
Amongst all of this university chaos, Iāve found myself reflecting on my summer position and all the exciting projects I had the opportunity to work on. My Research Assistant role was divided between two (2) teams, Plant Responses to the Environment & Biological Crop Protection, which meant so much learning across 18 different projects. Since we have no designated prompt this week (but still highlighted nature interpretation through science), Iād like to share two (2) of my favourite experimental and observational projects from the summer!
šøOrchid Shelf Life Assessment:
The Orchid Life Shelf Life Assessment was a 60-day trial where moth orchids Phalaenopsis were randomly assigned to three (3) levels of watering maintenance (none, light, and optimal). The plants were received from the growing company in two (2) types of substrates (sphagnum moss-based and bark-based) and at three (3) stages of bloom (100% bloom, 50% bloom, 0% bloom). Our purpose was to test if varying substrates affected the physical health and appearance of the plants, which was done through chlorophyll content index (CCI), leaf thickness, flower dimension, spike length, and root biomass measurements. There was also lots of counting of florets and photos taken throughout the trial! Although all of the time spent watering, caring for, measuring, photographing, and entering data for these 200 orchids was part of my job, it truly felt like my āPassion Projectā of the summer. I saw the project from start to finish, completed all the data collection, and also had the opportunity to write the Experimental Design, Measurements, and Data Collection portion of the final 23-page reportā so rewarding! The orchids who live in my bedroom are now in their dormant stage, but every time I tend to them I am reminded of the many orchid friends I made this summer. The trial also inspired me to start learning about wild orchid species native to Ontario and look out for them on trails!
šŖ³Horticultural Insect Identification:
All of theĀ Horticultural Insect IdentificationĀ work had been a multi-faceted project spanning many years before I started the summer position, but I was lucky enough to get full training and make a contribution to the trials! The purpose was to gain a better understanding of how the diversity of insects in greenhouses has been shifting and test the effects of potential management solutions. Although always fascinated by insects, my previous horticultural experiences (whether through summer positions or coursework) had never focused on the microscopic identification of insect species. I wanted to learn all about plants, so why would I worry about insects to THAT level? However, this project really taught me how interconnected plant and insect relationships are. Understanding insects could, in turn, make me a better plant scientist! Between establishing predatory mite colonies, developing Petri dishes with samples collected from plant washes, learning about the nuances between different thrips species, and hours upon hours spent looking at a microscope, the phrase āyou learn something new every dayā was very applicable. My main identification role was onion thripsĀ Thrips tabaci, western-flower thripsĀ Frankliniella occidentalis, and two-spotted spider mitesĀ Tetranychus urticaeĀ at varying stages of growth (egg, larval 1, larval 2, and adult). However, lots of other critters made an appearanceā my personal favourite were huge families of black bean aphidsĀ Aphis fabae.
Iāve included a diagram establishing the differences between onion thrips and western-flower thrips below, which are approximately one (1) millimetre long when adults! Most notably, western-flower thrips have red ocelli and are far more hairy than onion thrips.
I'm always happy to chat about these summer projects or horticultural work as a whole, so if anyone has questions, please don't hesitate to ask! I'm looking forward to checking out everyone's ideas for the free prompt this week :)
