succession or resource management. In this laboratory experiment, wheat (Triticum sp.) seeds were exposed to extracts from four plant species to determine whether or not these species processes inhibitors of growth. The extracts were from goldenrod (Solidago sp.), aspen (Populus tremuloides), black cherry (Prunus serotina), and aster (Aster novae-angliae). The quaking aspen is a deciduous tree native to North America. Aspens have shallow root systems, the ability to survive long term flooding, and formation
Introduction A gall is an abnormal growth that occurs on plant tissues. A plant growth is similar to a tumor or a wart that would occur on an animal; plant galls, however, are typically caused by various parasites and insects. In order for a gall to form, a female insect needs to implant an egg into a plant. It is important that the insect does so when the plant is maturing, this ensures the plants meristem is extremely active and prepared to grow a gall suitable for the insect’s young. The larvae
Warsaw, Missouri holds the record for both the coldest and the hottest temperatures ever recorded in Missouri ("Missouri Facts and Trivia"). The temperate deciduous forest is home to unique ecosystems and plentiful wildlife and vegetation. The temperature and precipitation in this biome is not too high or too low, hence the word temperate in the name. The terrain in the temperate deciduous biome has a great effect on the adaptations of the living organisms in the area. Missouri belongs in the
female fly is identified by their ovipositor, which is an egg-laying tube that extends from their body (Abrahamson and Heinrich, 2000). In order to protect their larvae, the adult female flies oviposit the eggs into the stem of the goldenrod plant Solidago altissima. While the females may lay several eggs per goldenrod stem, each plant usually ends up with one surviving larva in one gall. Once born, the fly larvae hatch from their eggs and begin eating the inside of the goldenrod stem. The larvae
Native Dye Plants of the United States The first to use native dye plants in the United States were the Native Americans. Their culture was totally dependent on what the land produced. This is reflected in the wealth of information Native Americans possessed about useful plants, from medicinal to ceremonial and dye plants. This is reflected in the types of houses they built and the names of places (often after the plants that grew there). Early European colonists foolishly ignored the wisdom of
