Thermal Tolerances Of The Invasive Macrophyte Hydrilla Verticillata, Joshua Williams Jan 2022

Thermal Tolerances Of The Invasive Macrophyte Hydrilla Verticillata, Joshua Williams

Graduate Research Showcase

Invasive species often rapidly spread due to their ability to adapt to a wide range of habitats they can occupy and lack of competition. Hydrilla verticillata is an invasive aquatic macrophyte that has spread across the United States due to human activities. Like many aquatic plants, Hydrilla has the ability to reproduce through fragmentation of the mother plant. In this method, Hydrilla fragments are then dispersed by water current to other areas where they can settle and grow. To date, little is known about the abiotic conditions that may restrict the spread of invasive Hydrilla. However, compared to other macrophytes …


Moss Composition Affects Seedling Density Of Western Hemlock And Sitka Spruce, Katy E. Maleta Ms. Jan 2016

Moss Composition Affects Seedling Density Of Western Hemlock And Sitka Spruce, Katy E. Maleta Ms.

Summer Research

Nurse logs at the Hoh National Forest represent a clear understanding of how important habitat heterogeneity is in old growth forests. Looking down a nurse log, you will find various moss species and debris along with seedlings being assisted in germination. By observation, there is an effect of moss composition on seedling density. We found that when moss depth increase, seedling density decreases. We also found that where the moss was the most thick, the moss species that was present was Hylocomium Splendens (Step Moss). We also found that when moss depth decreased, seedling density increased and the moss species …
