Busy Bees and growing trees
This week began with September peaking its head around the corner while we peaked at the maples’ new root growth. It was interesting to see some of our predicted root response strategies play out in real time. These roots are so predictable, how un-virgo of them. We also spent some time buzzing around flower beds and visiting the arboretum’s bee hives to get a look at the Apidae species responsible for pollinating lots of our plant pals. Keep reading for a more detailed review of the maples’ current root stats and a friendly introduction to some of the organisms that danced their way into September with us.
How are the tolerant silver maple roots responding differently than the tolerant star magnolia roots and what can this tell us about possible root strategies to deal with waterlogging stress? I’ll make one more call-back to last week’s blog post (apologies to the avid readers out there who are already keen on all of this info, but it’s wedding season and I’m trying to make it easier for those who were too busy doing the electric slide last weekend to check in). Okay, calling back my call-back, last week I mentioned the root strategy the magnolias deploy: die-back of roots when waterlogged, followed by a new flush of growth during the recovery period. The silver maples are doing something different. They are riders. They ride or die for their roots.
Above is a control silver maple (left) and a waterlogged silver maple (right). Looking at the blue tracings, you can see that both trees have a similar amount of new root growth. How are the silver maples mitigating tissue damage? We don’t know, but we can’t wait to find out! The stress tests we’re running to look at lipid oxidative damage and peroxidase activity should give us some insight.
We had fun with an unidentified bumble bee species (Bombus sp.). I didn't snap any pics of our friends this week but I'll be more vigilant next time so that we can get an ID on these ladies. Image source.
This is a hermit flower beetle (Osmoderma eremicola). It's a scarab type beetle, in the family scarabaeidae.
Some of our favorite recurring guests, tiger swallowtails (Papilo glaucus)! Hey fellas, how's the family?
Remember this fun guy from last week? Marvin found another chicken of the woods (Laetiporous sulphureus) and lucky ol' me got to eat it. It's as tasty as it is beautiful.
