Listed alphabetically based upon the last name of the first author, and move to the second author next, if there are two papers by the same author.)

please read the file that have information exactly how to find good secondary sources and how to find primary source
So as it says first find 3 secondary sources and in each of source annotated the source which mean write the summary information of the source ( When annotating your sources, try to write 2-3 sentences summarizing the information or type of content found in each source. The annotated bibliography should be useful to you. Often when you read a scientific paper you make summary notes in the margins or highlight key facts. These are what you want to summarize and to have to refer back
to in your annotated bibliography.
As with a Literature Cited section in a paper, the bibliography should have the papers
listed alphabetically based upon the last name of the first author, and move to the second author next, if there are two papers by the same author.) Then find two secondary sources and do same things
For my Animal which is chimpanzees i already have one primary and one secondary i will share it with you and you annotated them and cite them and you find the rest
1- primary sources: https://royalsocietypublishing.org/doi/10.1098/rsp…
2- secondary source https://animaldiversity.org/accounts/Pan_troglodyt…

Make sure you have your instructor

First, make sure that you get your favorite animal approved. Next, find 1 primary source and 1 secondary source that you could use for you Annotated Literature assignment. And 1 that is not an appropriate source. For the appropriate sources, you will (1) cite the source using the correct Literature Cited format, (2) indicate whether it’s a primary or secondary source, and why it it is that type of source, and (3) why it would be useful for your Favorite Animal Presentation (refer to the rubric). For the unacceptable source, you will cite it and indicate why it’s not appropriate. Make sure you have your instructor look over your the assignment before submitting it.

What factors (gear, assumptions, species biology) do you think affected the reliability of our estimates?

For turn-in:
Perform the calculations and report the information requested in paragraphs with boxes (?). Answer the questions 1- 4, above, as well as the summary questions below.
(5) Find two species that yielded very different results in seine vs. eletrofishing samples (eg, many in seine but not electrofish, or vice versa). Use what you know about the gear we used and the biology of those species to explain why we caught such different numbers with one gear vs. another.
(6) Given all the information we have, how many __Central Stonerollers__ do you think were present in the site? (Upper for Tues, Lower for Thurs) Which estimation method (census, batch mark-recapture, depletion) seems most reliable to you for that species, and why? What factors (gear, assumptions, species biology) do you think affected the reliability of our estimates? Assume that our data are “real”, and differences between estimates don’t come from mistakes on our part.
Fallfish seine census was 75, Chapman was about 202, and depletion was about 32. We know there were at least 75, because we caught that many seining.

Now that you have learned about food webs and biodiversity, you will virtually explore the environment in a state or national park. The table in Part II will need to be completely filled in and the answer to the questions in Part III will need significant elaboration.

Now that you have learned about food webs and biodiversity, you will virtually explore the environment in a state or national park. The table in Part II will need to be completely filled in and the answer to the questions in Part III will need significant elaboration. It is recommended that you explore every link at the site, which may include species lists, park history, park management, etc. If you have questions about the expectations, please reach out to your instructor for clarification.
Park Websites
The first thing we need to do is find a place to conduct our study. Think about a local park near you, and see if you can find their website online. If you cannot find their website, here are some very cool small parks around the country you can use; pick one. Garner State Park (Texas): http://tpwd.texas.gov/state-parks/garner Lassen Volcanic National Park (California): https://www.nps.gov/lavo/index.htm Big South Fork National River and Recreation Area (Tennessee): https://www.nps.gov/biso/index.htm Sabino Canyon (Arizona): http://www.sabinocanyon.com/ Devils Postpile (California): https://www.nps.gov/depo/index.htm Dry Tortugas National Park (Florida): https://www.drytortugas.com/ Black Canyon of the Gunnison (Colorado): https://www.nps.gov/blca/index.htm Scientists are trained to take very detailed notes when they head out into the field. This is because all of the information you can collect could be important to analyzing your data in the future. It is important to be descriptive and even use drawings if you need to make sure your data is as complete as possible.

Complete all parts of the survey based on your current lifestyle. How many earths would your lifestyle require if everyone lived the way you do?

This assignment is based upon your completion of an online survey located here:
http://www.footprintnetwork.org/en/index.php/GFN/page/calculators/ (Links to an external site.)
Experiment with this survey to complete these questions:
1. Complete all parts of the survey based on your current lifestyle. How many earths would your lifestyle require if everyone lived the way you do?
2. Based on the summary of your activities, what single change in your lifestyle would cause the greatest reduction in the amount of land your lifestyle requires?
3. Describe how your lifestyle would have to change in order to reduce your impact level to “1.0 Earths”?
4. Now complete the survey based on the lifestyle of your parents/guardians or a close relative who is about a generation older than you. How many earths would their lifestyle require if everyone lived the way they do?
5. Based on the summary of your relative’s activities, what single change in their lifestyle would cause the greatest reduction in the amount of land their lifestyle requires?
6. Describe how their lifestyle would have to change in order to reduce their impact level to “1.0 Earths”?
7. What are some of the flaws of this survey and the data it provides? What could be incorporated into the survey to correct these flaws?
8. Based on the reading, which do you think is the most persuasive critic’s perspective of the Ecological Footprint concept? Options include: analytical scientist, business person, pilot, fortune teller, robot, optimist, energy producer (Explain the concept and why you or others might agree or be persuaded by this perspective.) Submit your answers to questions 1-8 in the space below or as an attached (word or pdf) document.

What are some of the largest ecological cores you see in Fairfax, Loudoun, and Prince William Counties? (Name any nearby landmarks/park names) Also note what colors (scores) they have. Use the “Measure” tool next to the “info” tool on the bar to measure area. What is the largest size of a patch inside the beltway that you see? Change the units to acres or hectares. You can approximate the area measurement.

Note: Background information to supplement the lecture material is available at https://www.dcr.virginia.gov/natural-heritage/vaco…. For this exercise, you will be using the Virginia Department of Conservation and Recreation (DCR) online mapping tool. To start, go to https://vanhde.org/content/map. You will start with the layer Conservation Planning à Ecological Cores. You can also turn on the layers for VDOT roads as well as streams. Ecological cores include “identified large (>100 acres), unfragmented cores” via the GIS analysis of the Virginia Natural Landscape Assessment (VaNLA), and are given scores depending on ecosystem services provided – in general, larger more diverse areas are given higher scores. How many ecological cores do you see inside the beltway?
What are some of the largest ecological cores you see in Fairfax, Loudoun, and Prince William Counties? (Name any nearby landmarks/park names) Also note what colors (scores) they have. Use the “Measure” tool next to the “info” tool on the bar to measure area. What is the largest size of a patch inside the beltway that you see? Change the units to acres or hectares. You can approximate the area measurement.
Does this fit the general requirement noted by Lepczyk et al. (2017) for 10 to 35 hectares (~25 to 80 acres)? Do you think that means it is sufficiently helping to sustain populations of wild species? – why or why not? Look for a series of patches connected by minimal space. You can add the Conservation Planning à Natural Land Network layer on to help you with this, as this layer will connect all ecological cores ranked from high to outstanding together.
What are some connected areas you have found? What kind of shape do they make altogether? (linear, square, circular, dendritic, etc) Are these areas interrupted by road crossings?
What condition (seen as color) are these patches in? (Turn off Natural Land Network if you turned it on)
Zoom in and try to see if these are connected by a connected system of land management (e.g., Wildlife Refuge, county park/trail system) or if they tend to exist in a certain area in their watersheds (e.g., riparian areas, residential areas).
Next, keeping the Ecological Cores layer turned on, turn on the Managed Conservation Lands layer (under its own heading). You are going to compare areas under managed conservation lands to ecological cores. Compare areas connected by managed conservation lands and areas connected/identified as ecological cores. Which dataset seems to be more expansive in overall area? Using the definitions of ecological core vs. managed conservation land, explain why you see this pattern in spatial extent for managed conservation lands versus ecological cores. Fairfax County has lands designated a part of its conserved land network that include resource protection areas (RPAs) along all perennial streams within the county and certain 100-year floodplains, which are zoned for the Chesapeake Bay Preservation Act and Ordinance. Additionally, these conservation lands include those that are a part of the County’s Environmental Quality Corridor system (EQC) that was created to “identify, protect, and enhance an integrated network of ecologically valuable land and surface waters for the present and future residents of Fairfax County.” This land, mostly stream valleys, is designated based on achieving various ecosystem services, including one or more of the following: You are given everything you need to allocate 500 acres of land to conservation of habitat for biodiversity – in particular, limiting edge habitats that hurt various species of birds, plants, insects, etc. Pretending property rights don’t matter, how would you make the most of this land — would you expand on current corridors or try to create patches in more urbanized areas inside the beltway? There is no right answer, but explain your reasoning.
-Desirable or scarce habitat for rare/threatened/endangered species;
-Providing breeding habitat for aquatic/wetland organisms; -Potential corridor land for movement of wildlife and/or biodiversity conservation; and
-Riparian area providing shade, stabilization of stream banks via vegetation, flood storage, dissipation of stream energy, and other floodplain ecosystem services.
Figure 1. Example section of a stream valley included in the Fairfax County EQC.
You can read more at www.fairfaxcounty.gov/environment-energy-coordination/sites/environment-energy-coordination/files/assets/documents/eqac/2021%20eqac%20are_a-1a.pdf. Identify and name the general locations for a few managed conservation lands that provide connectivity between isolated ecological cores. Are they mainly in stream valleys? What is their general shape/size? Evaluate the general aim of the EQC system to connect ecological cores. Do you see any areas where conservation lands need to be expanded for the network of ecological cores? (Name a few.)
Identify some of the widths (in meters, m) of the managed conservation lands around streams that are a part of the EQC or RPA network, but not part of the Ecological cores. Large wildlife has been estimated to need corridors with ~ 2 km widths; birds have been estimated to need much less, with a parabolic relationship that leads to a positive relationship up to widths of ~50-80 m and a negative relationship with widths over 80 m (Askins et al. 2012). Do you think these conservation lands can benefit large animals? What about birds? What sorts of organisms do you think would be most benefited from these corridors?
Ecological cores require a large enough in-tact interior area to protect species from impacts of human activity, edge-thriving predators like foxes and raccoons, invasive species, and inbreeding. Looking at satellite imagery / landcover around the conservation network, what recommendations would you make to the EQC zoning to improve the success of the conservation corridors? Think about: Size Shape Insulation from urban habitat (“buffer zone”) Any other ideas you obtained from the lecture, reading Lepczyk et al. (2017) or https://www.dcr.virginia.gov/natural-heritage/vaco….
Figure 2. Parabolic relationship between bird species richness and width of corridors (example figure made from Askins et al. 2012).
Because property rights do matter, you cannot zone 500 acres of private property for your conservation aims. What are some small-scale habitat efforts you can push for or market for habitat and ecosystem conservation? There is no right answer, but explain your reasoning.
