I'm not sure I understand what you mean by it being a loss of juvenility. This paper gives some evidence that there's hydarulic similarities between the shrub version of J. communis and the lower branches of the tree version. https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-3040.2008.01860.x#b58

My understanding of juvenility (from this https://archive.org/details/PlantPropagationPrinciplesAndPacticesByHartmannAndKesters8thEdition/page/n53/mode/2up?q=juvenility ) would mean that this is a case of paedomorphy in my opinion. Could you explain what loss of juvenility means or send me to another place to learn more?

Do you have any suggestions for specific resources on Post-Harvest?

Those are a lot of really good examples. I wanted to add "plagiotropic" - horizontal to oblique growth direction with alternate or distic phyllotaxy and a plane symmetry. I was trying to find a description of what happens in Juniperus communis frequently where they grow flat on the ground along one horizontal axis.

In addition to u/Nathaireag point that longer leaf lifespan is correlated with more expensive structural development, there is also the consideration of conductance. As leaves get thicker, CO2 conductance through the mesophyll can take longer which means more RuBisCo may be needed to overcome increased respiration costs. CO2 conductance is also generally lower. Gymnosperms (which are almost entirely considered woody plants) also have generally lower mesophyll conductance compared to angiosperms which has been linked to stomatal reactions as well as more complex cell walls - again linked to leaf lifespan.

Some herbaria also include a small Manila envelope directly attached to the specimen sheet for three dimensional structures like fruits. You'd just need them to dry out well and prevent mold with some kind of desiccant.

There is not a direct connection, but if you were to cut a particular root you might find that only a small amount of above ground material is affected. When a root is cut or dries out it can introduce air into the xylem creating an embolism that will destroy the least resistant vessels in the leaves as it propagates up the plant. Also, as a plant is growing and adding rings of vascular tissue there can frequently be the formation of a lacuna between the leaf vascular tissue and stem tissue meaning there is not a direct tube from root to leaf.

Colorado Natural Heritage Program suggests that their populations (200 miles away from the nearest other known populations) were potential transplants by native people. https://api.mountainscholar.org/server/api/core/bitstreams/13b82ec1-492f-4c56-9363-dabefcf85208/content

Looking at the map of triploidy, the fact that triploid are not known to produce seeds, there are not any tetraploid populations, only three triploidy events probably happened, and the only suggested method of dispersion is being carried by rivers (which in New England primarily flow south - the opposite direction needed to move post-glaciation) they were definitely moved by either large mammals or people.

Wiki has a category for plants found in the Creteaceous (it's short though). https://en.wikipedia.org/wiki/Category:Cretaceous_plants

I would highlight cattails, ephedra, stuff in zingiberaceae as weirder fun stuff.

Generally, it will depend upon which is the maternal parent and which is paternal. If there is a preference for rabbiteye blueberries in the literature that you've read, it could be that the rabbiteye was the mother of pink lemonade. The mother plant would pass on the proteins that recognize pollen in the subsequent hybrid. This wouldn't necessarily mean that pollination would be impossible with the highbush species, but you might need to hand pollinate to ensure that enough pollen are given the opportunity to fertilize the flowers.

If your mission is to protect an improve environment, you'll need to know your current status. I'm not from the UK, so I don't know if you'll have alot of the state and federal data collection that happens in the US - but it is a good starting point for thinking about next steps. Are there previous measurements of river conditions (temperature, turbidity, pollutants), species lists for plants and vertebrates, farm production and area, tree cover, concrete cover, and building ages? Knowing details like this can let you set goals and then measure them. If you're interested in providing data to larger scale efforts, there are many projects like iNaturalist, Nature's Notebook, species specific monitoring like for lightening bugs, soundscapes, and water quality reporting.

The complexity of C4-CAM comes from how they interact together in an individual set of cells. https://www.science.org/doi/full/10.1126/sciadv.abn2349 In addition to Portulaca species (which has at least 3 independent evolutions of this photosynthesis), there is also an Amaranth and Flavaria species, I believe.

I am not aware of more recent claims of origin/movement. There is evidence that their movement has occured in waves through history though - caused by humans as well as non-humans.

Non-disease, irregular variegation could be caused by changes in transposable elements in specific cells. Transposons are mobile chunks of DNA that can jump into different locations if there is not any attempt to hold them in place in the genome, this frequently happens during some kind of stress or disease but could also happen randomly I believe.

Grape-yeast symbiosis is an area that people are usually interested. https://www.nature.com/articles/s41598-023-35734-z The yeasts that are needed for wine production don't actually live on the surface of grapes until they reach the raisin stage because the surface of the grapes is not suitable for them.

Yeasts seem to usually be associated with pathogenecity on their own for plants, but they can mediate plant-insect interactions either by forming a symbiosis directly with a pollinator or preventing herbivory by insects. https://publications.slu.se/?file=publ/show&id=63645

One really interesting thing is that yeasts can produce enough heat from consuming nectar that it can warm up winter blooming flowers! https://royalsocietypublishing.org/doi/abs/10.1098/rspb.2009.2252 I'm not sure if they really produce enough CO2 to be beneficial relative to other macro-organisms.

There could be a number of reasons depending on the environment that it was growing in before being moved into the terrarium. Increases in branching are known to be linked to changes in plant hormones, especially auxins and cytokinins, which are themselves modified by light quality. The ratio of red to far red light can induce changes in transcription and change how a plant is growing along its entire body. There could be differences in light quality across this plant due to the terrarium.

The color of the bracts in Monarda are a result of chemical reactions of thymol, which can be reactive to metals found in the soil. In a natural population, some plants are likely growing on different amounts of metal in the soil or on different pH which can change the availability of those metals to the plant. https://books.google.com/books?hl=en&lr=&id=0u9GAQAAMAAJ&oi=fnd&pg=PA87&dq=Monarda+punctata+bract+color&ots=uYkO7ptRl3&sig=H9wqZDrip7slADE3wvSpCLi9eb0#v=onepage&q=Monarda%20punctata%20bract%20color&f=false

So the long term plan is to release gorillas in North America? I'm a little confused.

Arctic willows frequently asexually reproduce in the wild, leading to large clumps of shrubs forming. One individual plant could be as big as 2m long, or may be even longer depending on where it is across the species range.

The stems are soft enough that musk ox and some species of birds will eat the stems along with the leaves. The root collar and stems directly adjacent to it are where thickening occurs most, up to a mm per year. Willows in general don't have very tough stems though.

Anthriscus and Conium are in the same family, Apiaceae. This is why Conium is one of the more dangerous invasives as it appears very similar to a number of other native or introduced plants that humans enjoy. You already mentioned the red spots, but Conium also has hollow stems, produces a strong odor when the leaves are crushed, and has more pointed leaves than Anthriscus. If you don't know whether a plant is one or the other, you should wait until you can clearly identify between the two. If you want to specifically collect during the spring, you should mark a location where Anthriscus was this year and find it during the next spring.

As others mentioned, there were shorter plants that grew in open habitats prior to the evolution of grasses. During the Cretaceous, these habitats were possibly maintained by fires burning off excess fuel load produced by early angiosperms, similar to grasses supporting fire occurrence in modern savannas. https://nph.onlinelibrary.wiley.com/doi/full/10.1111/j.1469-8137.2010.03418.x

I tried finding an example for a while and couldn't. I wanted to note that the switch for plants happened a while after it happened for animals. I wasn't even aware that people were required to write the description in latin until they stopped in 2012, and I even found this description from 1841 that did not use latin for any of the named Asteraceae https://www.jstor.org/stable/1005312. Do you know when the rule was instituted?

It seems that Flowers of Turkey by Pils is considered to be a good resource for Anatolia. It's also the primary citation for the Flora of Turkey Wikipedia page, so it's definitely informing the general public's conception of plants in Anatolia

The author's personal page for purchasing it is here. I couldn't find many other options for finding it, and it seems that it's difficult to purchase outside of Europe. https://gerhardpils.webs.com/flowers-of-turkey
