Journal Entry - Reginald

  1. The common earthworm is at the species level formally known as ""apporectodea caliginosa, once zoomed out we can see that this species belongs to the genus "lumbricinae" which branches off from belonging to the class "clittelata" which belongs to the phylum "annelida" under "trochozoa", "spiralia", "protostomes", "nephrozoa", "metazoa", all under "holozoa". Upon zooming out we see that it belongs to the domain "eukaryotes" ("eukaryoata",) branching off from "archea and eukaryotes" found under the kingdom "animalia" which finally branches off from "all life" ("biota").
  2. The specific adaptations that can be observed throughout the species has proven to be very diverse in this wet ecosystem of flaura and fauna making it very difficult to choose one adaptation that all species all share. However, all adaptations have been adaptations which rose from the ability to adapt to water as well as the ground and which we notice such as breathable skin (toads and frogs), the expanding and or elongating of body parts to create greater surface tension to walk or sit on water and or to be able to go in the water or be on land (like how toads have grown a thick skin to accommodate their life on land but they still go in the water to lay eggs) which all have been adaptations stemmed from increased access to oxygen and better mobility in and out of water (or on the water's surface).
  3. The american toad "anaxyrus americanus" has adapted a thick skin for life on land which also secretes toxins when they are in immediate danger (from predators). Although american toad's have developed a very thick skin and are primarily on land, they have kept the feature of webbed feat (which helps them both in water to swim and in land to move dirt) and still lay their eggs in water.

Journal Entry- Michelle Xu

  1. The aquatic flower pickerel weed at the species level is Pontederia Cordata, classified under the Pontederia genus, from the family of Pontederiaceae, branching from the order of Commenlinales. Furthermore, it is below the Monocotyledon class, then under the flowering plants (Anthophyta) phylum, and lastly the plantae kingdom within the Eukarya domain, fundamentally under all life.
  2. Their specific adaptations are relatively diverse, however they have the common characteristic of having possession of traits that allow them to adapt to their wet ecosystem, such as organisms having physical traits that give them the ability to float, granting them the advantage of having resources of both land and water. This can be shown through ducks and swans use of feathers and hollow bones to float, giving predatory advantage as well as maintaining easy access to oxygen and duckweed using water surface tension to stay on the surface, which is advantageous as it allows them maximum sunlight and oxygen for their photosynthetic processes.
  3. Water strider’s (Gerrini) adaption in water-based environment is their long hydrophobic legs, equipped for it stand and move on the water surface. Using water surface tension to their advantage, the hydrophobic micro hair on their legs allows its body to stay above the water, while the nature of their slender and long legs allows them to spread their weight evenly, overall able to travel on the water.

Journal Entry on Project Observations - Elissa

Hi everyone,

  1. Starting at the species level of the northern leopard frog, "lithobates pipiens", we can zoom out on OneZoom to see that this frog is part of the "Lithobates" genus, is considered a "True frog", and is also part of the family "Ranidae". As we zoom out further, we see that l. pipiens belongs to the the order "Anura", class "Amphibia", which was then linked to "Tetrapods", then "Vertebrates", then the phylum "Chordata", reaching "Nephrozoa", "Holozoa", the kingdom "Animalia", and "Eukaryotes", which then branched off of "Archae and Eukaryotes" and ultimately "all life".
  2. Our observations demonstrated great diversity in the flora and fauna of wet ecosystems, so it is difficult to choose only 1 adaptation common to all, however, the majority of organisms had adapted to life around water and it was observed that certain plants and creatures were able to float on the water's surface by expanding their bodies or developing large leaves to increase surface area and take advantage of the water's surface tension (water striders, spiders, water lilies). More specifically, it was noted that some insects used this particular adaptation to move around a body of water with great ease (locomotion).
  3. A unique adaptation that was not common to other observations was the velcro-like quality of the pods of the plant "Desmodium Paniculatum". The triangular, fuzzy pods readily stick to clothes and animals, which allows them to be carried far and wide to help propagate the plant's seeds (reproduction).

Feedback

Hello everyone!
These are really cool observations. I see a lot of ob different species to chose from! Keep in mind that you can use this journal platform to make your observations and discuss the adaptations of a particular species of your choice!
Looking forward to seeing more observations!
Daniel
