Nutrient Cycling In The Amazon: A Comparison Of Soil Characteristics, Insects, Root Types And Decomposition Rates Between Varzea And Terra Firme Habitats In The Ecuadorian Amazon, Mira Ensley-Field
Independent Study Project (ISP) Collection
Decomposition and nutrient cycling form the basis of every ecosystem. Nutrient availability in the soil affects plant species composition, richness, and productivity. The Amazon rainforest is known for its unusually fast nutrient cycle, but many aspects lack detailed study and analysis. This comparative study carried out in the Ecuadorian Amazon had four primary objectives related to understanding the nutrient cycle in the Amazon; 1.) analyze soil characteristics, 2.) assess insect diversity in the leaf litter layer, 3.) examine root characteristics, and 4.) measure the decomposition rate between Varzea and Terra Firme habitats alongside the Rio Napo.

Microclimate Variation And Epiphyte Distribution In Acer Macrophylum, Jeremy Wood
Microclimate Variation And Epiphyte Distribution In Acer Macrophylum, Jeremy Wood
Summer Research
Habitat heterogeneity plays a key role in supporting biodiversity in both animals and plant life. More diverse environments provide more exploitable niches across gradients in temperature, humidity, light availability, and countless other variables at the landscape and regional scales. In specimens of Acer macrophylum in the Hoh Rainforest, we found significant variation in temperature and relative humidity across particular crown zones, and certain epiphyte species were found to distribute according to such microclimate variation.
