Lab 2 journal

One species that caught my attention during this field lab was the Butternut, also know as Juglans cinerea. This species was interesting because it had fruits that are lemon-shaped, almost resembling a kiwi. After further research, I learnt that this specie does not leafout in spring because of an increase in temperature, like many would think. Instead, they grow because of photoperiodism, meaning that it's the increase in daylight helps them spring. Another interesting fact about the butternut is that its seasonality is all year long. Even if they are rarer during the winter period, they are still there! Lastly, an adaptation that all of my observations had in common were their green leaves. Their green colour stems from the chlorrophyl that composes it. Chlorophyll helps them absorb sunlight, and since many of my observations were short sized, they need more help absorbing sunlight.
