During this time students should simply pick out as many living things as possible from their dishpan. How do populations change in the Hudson River ecosystem, and how do these changes affect the larger ecological community? They are also usually able to identify biotic interactions such as predator-prey relationships.

When people think of ecology, they usually imagine studies out in the country. Students will know how the water cycle has been altered by humans using local data. The curriculum also encourages students to develop and test claims comparing different forest types. Overview of what lives in the Hudson River. For this experiment data collection will take place in three major steps: 1) Pick, 2) Sort/Identify, and 3) Count. This dislodges the invertebrates that live in these areas and the current washes them into the net. Wetlands play a vital role in protecting habitats for fish and other wildlife, improving water quality, and creating a buffer for storm surges and floodwaters.
The speed of water in each microhabitat affects the types of macroinvertebrates that live there. Image by Greg Schechter. Subscribe to our Latest from SciPol newsletter  for general SciPol updates. Students will know that environmental changes act as a selection filter and be able to explain these processes using the example of cadmium resistance in Foundry Cove mud worms. Learn about the ways climate change is deeply altering how we live, where we live and the foods we eat -- ultimately threatening some of our most basic human rights. Students will know how to test for turbidity in their local stream and will be able to explain whether their stream is contaminated by turbidity. Students will know that the presence of humans has an impact on soil communities in their schoolyard. Students should be able to name biotic vs. abiotic factors that they observed in the stream.Abiotic factors include: water temperature, dissolved oxygen, speed of the water, and substrate. A dataset from the Hudson River showing dissolved oxygen changes over 24 hours. Do seed eaters have preferences for specific kinds of seeds? Dataset representing wildlife encounters recorded by trail cameras during the late summer and fall, 2015-2016. Is there any correlation between temperature increase and cellular respiration/photosynthesis processes? Students will know how the climate of the Hudson Valley has changed over the last 400 years and be able to explain these changes. Help them think about the observations they made at the stream in biotic and abiotic terms and how these observations are connected. Photos of commonly found invertebrates in leaf litter. Students will know how to answer the question, “How likely is it that a striped bass caught near where the students live on the Hudson River will be above the FDA supermarket standard of 2 ppm?” and be able to provide evidence to support their answer. Learn about the ways climate change is deeply altering how we live, where we live and the foods we eat -- ultimately threatening some of … As one large group it is now time to tally all the data for the pools and then the riffles. Other smaller organisms from a water sample can also be seen under a dissecting scope (daphnia, copepods, etc.)
In the case of stream ecology, scientists are often concerned with the organisms – such as plants, animals, and bacteria – that live in and on the water as well as the larger organisms that depend on the health of the water for their wellbeing. Aquatic Ecology Paper Topics .
For example, when discussing stream ecosystems students will be able to articulate that the amount of water or temperature might affect the types of fish that live in a stream. The central investigation of this unit helps students answer the question "Where does the stuff living things are made of go after those organisms die?" If so, what processes are involved that may influence the amount of rainfall, or throughfall, that reaches the ground? Students will know that plants use oxygen underwater and be able to design an experiment that will test this question. Field checking is the process of verifying a land use map by physically checking the schoolyard. It is extremely important that students immediately write down “pool” or “riffle” on their data sheet (can use the “Team Data Sheet: Macroinvertebrate Data” found in the Stroud leaf pack network data sheets below), as well as the sample number they are working on. Long term data from the Hudson River showing both dissolved oxygen and fecal coliform bacterial counts.
Dissolved oxygen (D.O.) Student collect data about their schoolyard, neighborhood and town to estimate the amount of water that runs off these places into a nearby stream. These data show the annual average water temperature for the Hudson River at Poughkeepsie, NY from 1946-2012. Using aerial photographs Land Classification to determine what covers the schoolyard Land cover percentage (Building on skills from “Candyland Elementary School Land Use” lesson).
Students will be able to discuss the life cycles of common macroinvertebrates and use data to compare macroinvertebrate larval abundance to adult numbers and make inferences. Tropical Stream Ecology describes the main features of tropical streams and their ecology. Using data from the Hudson River Environmental Conditions Observation System (HRECOS) you can track the storm and its effect on the river.
What eats it? Some taxa of macroinvertebrates eat dead and decaying leaves, how might the terrestrial plant community affect the macroinvertebrate population in the stream?
This reading includes basic ecology of the water chestnut, along with information about the invasion of this plant in the region. Discuss the salt marshes ecological phenomenon ; Describe the … Wastewater enters the Hudson River from point sources including municipal and industrial wastewater treatment plants, combined sewer overflows, urban storm water, and tributaries of the Hudson River such as Fishkill Creek.
The Hudson River Environmental Conditions Observing System (HRECOS) is a network of real-time monitoring stations along the Hudson River. Students will also gain experience analyzing data by exploring how levels of PCB's vary over time, location, and between different species of fish. They should be answering and thinking about questions such as: What plant community dominates the creek bank? Illustration of acids, hydrogen ions, and a PH scale of water sources. The toxification of the Hudson River has had a dramatic impact on the health of the river's ecosystem as well as the ability of people living along the river to use and enjoy it. Are these changes permanent, and how will the ecosystem respond? These "biology briefs" provide a line drawing of common aquatic macroinvertebrates, plus information on their feeding habits. Students will know how a stream changes during and after a storm and be able to create and/or interpret graphs demonstrating these changes. Does the total number of insect species differ in different parts of a forest stand? Students recieve a request to survey animals and their food resources on a local site, then talk about what they already know and how they could find out more. Does the amount of light affect the plant respiration and CO2 production rate?
Students will know how streams become polluted with salt using first and second hand data, and will be able to make a prediction about future chloride levels in their local watershed stream.
Data show a 123-year record (1885-2008) of first arrival date of select migratory birds in Dutchess County, NY. Questions arise out of scientific experiments that lead to other experiments.
Understanding how human activity influences the Hudson is a prime concern for the maintenance of the river, especially as the human population grows. Which soil and leaf litter-dwelling organisms live here?
This unit introduces students to the ecosystem concept using the Hudson River ecosystem. Are high volume flows threatening to erode stream banks? Freshwater tidal wetlands are a unique ecosystem of the Hudson River estuary, and these lessons will help students understand their importance along with some of the challenges due to a changing climate. This unit is unique in that it focuses on collecting long term data about the changes in the populations of macroinvertebrates. Students will know that mud worms at Foundry Cove evolved cadmium resistance and be able to explain how the scientists verified that cadmium-resistance is an inherited trait. Data was collected near Kingston, NY. Photos and descriptive information about common invasive plants found in and around Dutchess County, NY.
