      I never heard of this before but this is cool concept. Ecotone a transitional area of vegetation between two different plant communities such as forest and grasslands

    2. Reconstructing the nature of the original forests is not justan academic exercise in historical ecology, phytogeographyor vegetation ecology, but should be applied to future edu-cational, management and conserv

      As the years go by land is becoming limited. This means that people will need places to live. This ends up causing deforestation in the long run and all the ecosystem will eventually vanished. Teaching these type of values

    3. hical sequence typified bybeech while the southern vegetation is an amorphous grou

      I feel like im not understand when they mean by amorphous

    4. dominant taxa. Oak, spruce, hickory andchestnut reach distinctive range limits within

      not surprised since these species are so common in the east coast

    1. environments, but they, in turn, alter their environments to

      never thought of it like this. It makes sense but i do wonder how would plants and trees do this when wind dispersal occurs? Kinda similar to the orchid study we did a week ago or two.

    2. ited States, persimmon is nearly a for-gotten f

      I never thought of this before. Made me wonder what happens to fruits that were cultivated in the past and were forgotten? would these plants revert on their evolution because the human population somewhat forgot about them or will they eventually adapt to the point where it may not be consumable.

    3. North America. Plant domestication is a major theme in the study of human–nature interactions

      Yes we can name a bunch of veggies that changed so much over time such as watermelon and corn. There is some studies that even Cannabis is going through some evolution. file:///C:/Users/Surplus/Downloads/Seegehalli-et-al.pdf

    1. ree species composition can vary significantly across soil types and topography within the same geographic area

      Yes i agree on this. I believe that the pH in soil is able to determine what plants live there. I think there is a certain scale for a plant for that can handle pH. i believe azaleas would consider acidic soil in order for them to thrive.

    2. ethnobotany

      I never heard of this term before reading this paper. its actually interesting. it reminds me of sociology and botany mixed together. I think its interesting to learn what tribes used for their medicine back in the day and to see if we can use for modern medicine to further human health.

    1. The structure of a morphospace is determined by the choice of thecharacters to include and by the way these characters are coded

      Does this help out map out phylogeny trees?

    2. ce. Morphospaces are usually visualized with the help of ordinationmethods such as principal component analysis (PCA) or nonmetric multidimensional scaling(NMDS). T

      I feel like im not understanding what morphospaces mean. Im sitll a bit confused what its stating

    1. Transcriptomics

      Could anyone explain to me what this section was talking about? I feel like im not sure what they are saying about transcriptions and how they were able to test that in med. plants ?

    2. Medicinal plants are a rich source of highly diverse specialized metabolites with important pharmacologicalproperties

      Ill agree with this because in my years of owning fish i was able to use certain plants to help medicate the fish i have in the fish tank ( 75 gallon). they were goldfish and they tend to be pretty dirt animals. For example i learned that rosemary helps infections for fish. it was useful whenever the tank had bacterial infection. I was able to tell if it was a bacteria because there is white film or the eyes look more cloudy than use ( depending on their age). Sometimes we will add rosemary in small increments because the aroma of the plant is strong and i didnt understand how much itll affect the pH.

    1. While the tattoos, preserved in the permafrost, have been known about since the remains were dug up, until now few have seen the intricate reconstructions that we reveal here.

      I think this is interesting because I did more research on the this oil. there is other studies that suggest that this oil does have an impact on the mircobiome. may lead us to think why we have these other oils that show us no benefits but this one actually does. https://pubmed.ncbi.nlm.nih.gov/25223749/

      I think this is interesting because in my capstone class for biology I am looking at how cannabis affects the human mircobiome. There tends to be a positive corelationship on how the human mircobiome was able to be influenced by the consumption of the plant. the article below is one of the paper i will be using and i think you find this fascinating https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0099641

    1. opulations in previously glaciated regions are often genetically depauperate in comparison with populations at lower latitudes,due either to bottlenecks experienced in post-glacial colonization or to contemporary genetic drift in small, peripheralpopulations

      i think its interesting that this article is stating that the higher latitude species have a less diversity due to the unfavorable conditions in the environment at the higher altitude.

    1. Connecticut and Massachusetts had the most records of specialist-bee species in the region (56 and 54 species, respectively).

      I lived in mass my whole life. When i was younger, i used to see plenty of bees in my area. Especially since i live 10 mins south of boston.I am currently 24 years old and i rarely see bees in my area. When I do, i feel like its a lone straggler. I feel like ive seen the decline of pollinators in my area during my life time.

    2. Recently documented declines in pollinator populations threaten the resilience of ecosystems, societies, and economies

      Pollinators are vital to creating and maintaining the ecosystem. a lot of species of animals and plant depend on these creatures. a lot of our foods depend on these species. I think its just devastating how much pollinators declined overtime.

    1. Our study implies current geographic and genetic distributionofS. procumbenss.l. is likely to have been shaped by changingclimates in both the Neogene and Quaternary periods.

      this was a really cool article. I would not think that a genetic distribution of S procumbens would be effected by climate change. I didnt know these plants were endemic to seychelles.

    2. we newly sequenced three chloroplastnon-coding regions

      i remember reaeding a article of this not so long ago for a different class for a project at my old school . I will like to share the link to it but i will like to say introns are derivatives of self-splicing ribozymes that have become dependent upon proteins for their splicing.

      https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2217634/#:~:text=Land%20plant%20chloroplast%20genomes%20contain,upon%20proteins%20for%20their%20splicing.

    1. Relative rate of photosynthetic efficiency at low light levels, tolerance to air and soil moisture, and winter snow depth are probably the most impor- tant factors in the selection of species and commu- niity types in the fog-moisture gradient

      Photosynthesis is slow during the winter times. this affects the respiration and growth of the plant and it makes sense because if you look at lawn in the winter time, you ever realized that grass is barely growing but in the summertime the grass gets tall and eventually have to mow the lawn.

    2. One to three soil pits were dug within each community type, soil profiles were described, and roots examine

      i find this interesting because when I was in the presidential loop one thing that concurred with me is that the plants were brittle because of the temperatures and crazy weather.

    1. Third, euphyllo-phytes have a molecular apomorphy, a 30-kilobase inversionlocated in the large single-copy region of chloroplast DNA

      This is interesting to me because I didnt know what apomorphy. when doing some research. I feel like i still dont get what it means. I just understand it has to do with its ancestors.

    1. Land plants and charophyte algae (together called strep-tophytes) have the canonical plant phytochrome structure, characterized by having a PAS–PAS repeat and a histidine-kinase related domain (HKRD) in the C-terminal regula-tory module (Li et al. 2015a) (Fig. 1b).

      i think this is interesting because i didnt know the plant pytochrome influence the development of a plant. such as timing when a plant begins to flower.

    1. hemiparasitic plant mistletoe

      I didnt know what this meant and learn that these plants contains chlorophyll and still does photosynthesis. it attacks the roots and shoots of the plant. Its weird to think about.i would never thought a mistletoe plant will be considered to be hemiparassitic.
