  • Milkweed Hypothesis

    having more time to produce pods, or have a more extensive root system to acquire nutrients necessary for pod production. Some of the variability in pod numbers observed for may be because milkweeds produce stems periodically thorough the growing season, so during the summer, different stems may be in different life stages. Milkweed also grows from underground rhizomes, which may produce clones of the parent plant nearby (“Milkweed Fact Sheet”, n.d.). Because of this, with the hula-hoop method we used, the samples were likely not independent. Another source of variation may be due to a trade-off between the size of the seeds in the different sized seedpods and the dispersal ability. Morse and Schmitt (1985) found that in the common milkweed Asclepias syriaca, there was a negative correlation between seed size and dispersal ability, with smaller seeds dispersing further, and larger seeds having more success in germination. They found a large diversity in the morphology of the seeds among clones and the pods within clones, so seed, and perhaps pod size, is not genetically determined by a clear mechanism. This would make a trade-off between growth and reproductive resource allotment difficult to detect. There is no statistically significant relationship between the height of the milkweed and its duration latex flow in our study. This contrasts with results obtained by Züst, Rasmann, and Agrawal (2015), which found a positive relationship between plant growth and latex…

  • The Battle Of Shade And Sun: Monarch Butterfly

    "Temperature and Survival," "freezing temperatures can kill about 50% of the monarch population, while wet weather can kill 80 to 90% of the monarch population." Monarch butterflies enjoy basking and warming their wings in the sun. But there are also many monarch attracting plants that can be grown in the shade. "Types of shade tolerant plants include Asters, Purple Coneflowers, Purple Milkweed, Aquatic Milkweed, and Marsh Milkweed" ("Backyard Habitat"). Though since these plants can be…

    earliest civilizations. • The Sumerians (circa 4000 BC) constructed the earliest known health complexes that were built around hot springs. These healthcare facilities included majestic elevated temples with flowing pools. • During the Bronze Age (circa 2000 BC), hill tribes in what is now known presently as St. Moritz, Switzerland recognized the health benefits in drinking and bathing in iron-rich mineral springs. The same bronze drinking cups that they used were found in thermal springs in…
