The document discusses the Asian carp, an invasive species introduced to the US in the 1970s that threatens the Great Lakes. It notes that Asian carp eat plankton that native fish rely on and that silver carp can injure people when they jump out of the water. While many proposals seek to control the carp population, one suggestion is promoting their use for human consumption, as they are farmed and popular to eat in Asia. Some chefs say Asian carp are delicious.

Asian Carp InvasionRoss Swanson

The document discusses the invasion of Asian carp into the Great Lakes. Asian carp were introduced to the US in the 1970s but escaped into rivers due to flooding. They have since proliferated and migrated north, threatening the $7 billion Great Lake fisheries. Efforts to stop the carp include electric barriers on the Chicago Canal and plans for physical barriers or hydrologic separation. Removal efforts focus on netting and killing carp in key areas.

Silver and bighead carp, invasive species originally brought to the US from Asia in the 1970s, have overpopulated the Illinois River and are threatening to enter the Great Lakes. These filter-feeding carp consume large amounts of plankton and outcompete native fish, while their population continues to grow rapidly. Various control methods have been attempted, including commercial fishing tournaments and plans to install electric barriers at channels connecting to the Great Lakes. Some efforts promote eating the carp as an alternative protein source.

Animals in Danger lujanedit

��

Many animal species are endangered or face extinction due to natural causes like disease, competition, and natural disasters, as well as man-made threats including poaching, habitat loss, and commercial exploitation. Specific animals mentioned that are endangered include the Iberian lynx due to habitat loss and poaching, polar bears whose sea ice habitat is diminishing, tigers whose bones and body parts are used in traditional medicine and habitat is destroyed, gorillas whose forest habitat is invaded and destroyed from human activities, and pumas which depend on intact habitats for survival.

Blue whale[2]guestd20829

��

The blue whale is the largest animal on Earth. It can grow up to 110 feet long and weigh over 200 tons. Blue whales are found in all oceans and feed mainly on krill and small fish. They were heavily hunted for their oil and baleen in the 20th century, and are now endangered with only around 10,000-25,000 remaining. International bans have protected blue whales since the 1960s, but threats like pollution and climate change still endanger the species.

The blue whale is the largest animal on Earth, weighing up to 200 tons and having a heart the size of a Volkswagen Beetle. It communicates using extremely loud calls that can be heard for hundreds of miles. While commercial whaling has ceased, blue whales remain threatened by environmental changes, ship strikes, and fishing gear entanglements. The annual drive hunts in Taiji, Japan result in the brutal killing of hundreds of thousands of dolphins and small whales over the fall and winter months using methods that can take many minutes for animals to die. Despite introducing a dolphin swim program, the people of Taiji intend to continue their traditional slaughter.

The scalloped hammerhead shark has a distinctive hammer-shaped head, with olive, bronze or brown coloring and white belly. It lives in warm tropical waters off Australia and Central America, ranging in size from 3 to 26 feet. Experts estimate that 73 million sharks are killed annually, including 3 million hammerheads. Hammerheads prey on fish, squid, octopus and crustaceans, and have even been known to eat their own young. Their wide-set nostrils and eyes at the end of their hammer-shaped heads help them detect prey and threats. However, their large size makes them vulnerable to overfishing, and their valuable fins have led to the hammerhead being classified as an endangered species.

The chaparral biome is found mostly in California. It has dry soil, receives sunlight, and hot summers as its abiotic factors. Plants and animals in the chaparral, such as cacti, trees, jackrabbits, coyotes, and spotted skunks, are adapted to the lack of water and heat. Competition for limited resources occurs between species, such as coyotes fighting for food. The average precipitation is 30 inches per year with an average temperature of 50-60 degrees Fahrenheit and temperature ranges up to 110 degrees. Proper clothing includes shorts and short sleeves while shelters are made from natural materials like rocks. Threats include development, global warming, and endangered species losing habitat from less

Gray whales migrate between feeding grounds in the Arctic and breeding grounds in Baja California. They use echolocation and their baleen plates to filter feed on small creatures in ocean sediments. Gray whale numbers were nearly decimated by commercial whaling but have rebounded to around 20,000 thanks to international protections. Some western Pacific gray whales remain critically endangered with only around 100 left.

Deer And Elk Iconic Early Seral WildlifeEcoshare

��

Deer and elk populations have historically fluctuated in Oregon and Washington due to factors like overhunting and severe winters. These species prefer early seral forest habitat after disturbances for food and cover, though their dietary needs differ. Many other wildlife species also rely on early seral forests for various habitat structures and food sources. While deer and elk populations can indicate early seral forest quality, managing solely for these species would not meet all habitat needs for the diverse wildlife that depend on early seral forests.

Ottersreedsterscience

��

Sea otters live in coastal areas near Alaska, Washington, and California. They eat crayfish, crabs, fish, and frogs, consuming 15-20% of their body weight daily while floating on their backs. Sea otters can live up to 25 years, though most live 10-12 years. Females are ready to mate at 3-6 years old and give birth after 5-8 month pregnancies. Sea otters have large predators including humans, sharks, bears, eagles, and killer whales.

Sea OttersMrs. Drouare

��

Sea otters primarily eat fish and sea urchins, consuming 20-25% of their body weight daily as they are carnivorous. They live in coastal areas of the northern Pacific Ocean from Alaska to California, preferring shallow waters. Sea otters are endangered due to past hunting during the fur trade which reduced their population from 150,000-300,000 to the thousands today. Their predators include sharks, humans, and bald eagles, and they will swim to shore to escape sharks.

��

This study aims to quantify the amount of nutrients deposited by nesting loggerhead sea turtles and determine if these nutrients enhance the resilience of coastal dune systems. The researcher will measure the nutrients contained in unhatched eggs and egg shells left after nests hatch. A sea oats experiment will test if the plants gain mass by absorbing nutrients from eggs. Preliminary results from 2012 found over 80,000 grams of biomass deposited across 20 nests, with most hatchlings emerging successfully. Continued analysis in 2013 will include dune stabilization tests and examining nest density patterns using GIS.

Invasive species have caused major environmental and economic impacts in the United States. They have contributed to the endangerment or extinction of 49% of threatened species through competition for resources. Many invasive species were introduced accidentally through ballast water or deliberately for agriculture, recreation, or the pet trade and have spread widely. Individual actions like cleaning gear and draining water from boats can help limit the unintended transport of invasive species to new environments.

Fresh Water Turtleslrl2631

Freshwater turtles have a bone or piece of cartilage that develops into a shell on their back called a carapace, with a lower plate on their belly called a plastron, connected by bony bridges. Their shells are made of keratin and have a dome shape for protection. Turtles have short, webbed legs and must surface to breathe air, though they can spend time on land. Female turtles choose their mates and lay eggs without parental involvement. While male turtles fight each other to mate, they only provide fertilization. Endangered freshwater turtle species include the Red-Crowned River Turtle. Some turtles, like red-eared sliders, are kept as pets.
