The accuracy of the map can be improved through the knowledge gained by field checking. Full Title: Linking community and food-web approaches to restoration: An ecological assessment of created and natural marshes influenced by river diversions This project will investigate how river diversions influence the living communities, food web structure, and function of created versus natural marshes to inform the development of marsh restoration strategies. Third-party cookies: The function of this type of cookie is to retain your interaction with a particular website for an entity that does not own that website. Are there differences in rates of evaporation in shaded, forested areas versus full sun, open field areas? They will learn how differences in land cover type may lead to difference in ecosystem (biological, physical and social) features, and how biological, physical and/or social features of an ecosystem can be inter-related. The Hudson River has one of the highest levels of PCB pollution of any river on the East Coast. Practice: Food chains and food webs.

Students will know how to test for salt pollution in their local stream and will be able to explain whether their stream is contaminated by salt. The United States Geological Survey (USGS) has a network of real-time monitoring stations located along many waterways in New York State. What happens to streams when it rains, both in urban and in rural areas? They also imagine studies that show how organisms relate to the physical environment -- air, water, and soil. Marsh is a major broker in the food and beverage sector, working on a global level with some of the most well recognized food and beverage companies internationally, as well as small to medium sized companies.

Biology is brought to you with support from the Amgen Foundation. Salt Marsh (from: Mitsch and Gosselink, 1993) Producers in a salt marsh include the marsh grasses, Spartina and Juncus mostly, plus various other salt tolerant plants as well as lots of algae. All scientific maps need to be verified by fieldwork (exploring the schoolyard). Typical marsh conditions stimulate aquatic plants to grow, which serve as an abundant source of energy and provide food and habitat for a variety of organisms. Students collect data about the "seed rain" in the their schoolyard, while also learning to identify trees and seeds in their schoolyard. By using this website, you consent to the processing of data about you by Google in the manner and for the purposes set out above. By 1992 they had spread throughout the freshwater and slightly brackish parts of the estuary and had a biomass greater than the combined biomass of all other consumers.

This dataset shows dissolved oxygen changes over seven years in the Hudson River, clearly showing the differences in seasons (both temperature and dissolved oxygen). Even large raptor s such as osprey are supported by tidal salt marshes. Which ground dwelling insects live in this area? Land cover types can be measured by using a grid overlay to aid in determining percent coverage. Marsh creates tailor-made strategies to manage today’s risks. Students will hypothesize how a storm event might change the physical and chemical characteristics of a local stream and be able to collect data to support or negate their hypotheses and communicate these results to others. Do large soil organisms (e.g., worms) speed up decomposition? Through soil testing and map reading, they learn that soil composition varies from site to site depending on the underlying rock type, overlying vegetation, time, topography, climate, and chemicals carried by water percolating through the soil. The SWEAP materials and activities assist teachers in guiding their students as they compare the ecology of three small watersheds with different land uses (e.g., agricultural, forested, developed). Are there differences in the CO2 levels in different areas of the school campus?

The birds are producers. Does the total number of insect species differ in different parts of a forest stand? The team will use these data to develop a model that predicts how river diversions will affect marsh food web structure, function, and resilience. Through a game and outdoor investigation, students compare the behavior of animals in different areas of the schoolyard and experience an authentic ecological research method. In this unit, students explore how fracking might affect turbidity levels using secondary data from streams in Arkansas and a first-hand investigation on turbidity in a pond microcosm. Healthy aquatic habitats usually have dissolved oxygen levels at or above 80% saturation. They usually store an anonymous session ID allowing you to browse a website without having to log in to each page.
