This had a huge effect on the planktons. Zooplanktons the eat phytoplankton. If there isn’t much phytoplankton for the zooplankton to eat, there numbers will decrease. The article “ The Short‐Term Impact of the Zebra Mussel Invasion,” “phytoplankton fell by 80 percent. Zooplankton (which eat phytoplankton) declined by half.
They can consume up to one liter per day, some of the particles that are consumed are used for food but they mainly eat plankton. The other particles are combined with mucus,other matters which are deposited on the floor of the lake since they are useless to the Zebra Mussels. In this research we will be talking about how the Zebra Mussels Impacted the Great Lakes, and what the effects were and if they were positive or a negative effect. Results: 300-400 words Invasive species has always been documented to have negative harm to the environment but Zebra Mussels are invasive species that have a negative harm and also a positive effect to the environment.
For many it’s a first pet, a gift from family, something you won as a prize at a carnival, but for Canadian residents the familiar orange goldfish everyone knows and loves is becoming a serious problem. Some flush them in a hurry because they no longer want to take care of them, others commit them to a porcelain vortex because they believe their beloved fish has passed, and the Canadian Government is issuing a warning now to citizens of Canada to stop flushing their fish. Just a few goldfish with the potential to disrupt an entire ecosystem Goldfish are entering the ecosystem the way that a lot of invasive species end up in an environment they don’t belong, Humans are putting them there. Human interference is one of the leading causes of the beginning of over population of invading alien species. In this case many of the fish are going down drains, and ending up in Canada’s lakes and rivers.
The fishing economy worth $7 billion in WI is also affected by the quagga mussels. There are five times more quagga mussels than fish in Lake Michigan. Quagga mussels eat plankton which is the food supply for
Their activities also disrupt the work of fish farmers by destroying large number or
Woolly mammoths (Mammuthus primigenius) have been extinct for a very long time, with the last of the species dying out about 3,600 years ago. But researchers say it may be possible to bring these and other extinct species back from the grave. There is significant controversy and critics over the idea of bring back to life and assert that efforts would be better spent conserving existing or endangered species. Critics of resurrection say reviving extinct animal could do more harm to conservation efforts than good. As for me, I would be disagreeing with the idea proposed.
THE ZEBRA MUSSEL INCIDENT The Zebra Mussel Incident Zebra Mussels are an invasive species which now dominate the Great Lakes region, they were introduced in the 1980’s and ever since then their quantities have increased dramatically. Since the time they arrived they have caused many problems including problems in the ecosystem and with the economy. Human’s have been trying ever since their arrival to eliminate or reduce their quantities but not much progress has been made. Right now Zebra Mussels are one of the biggest issues affecting the great lakes.
Invasive species are a big problem to the United States ,because they can cause billions of dollars in damage. In this paper it will reveal some of the most known invasive species in the Florida everglades. The different Invasive species that will be discussed are the Giant African Snail, the Brazilian Pepper Tree, and the Cuban Treefrog. The first invasive species is the Giant African Snail. It originated from Africa and was first presented to Florida as being a pet.
Killer whales, more properly known as orcas, have been kept in captivity since 1961, helpless victims of a blatantly commercial experiment which has seen dozens of wild orcas plucked from their families and forced to live in artificial social groupings which bear scant resemblance to their natural order. Unaware of their plight, millions of people flock each year to watch the orca show, seduced by the extravagant promises of the display industry. Glossy brochures herald a spectacle - billed "The Wettest Show on Earth!" which will simultaneously entertain and educate the whole family. Visitors are invited to enter a fantasy land, where orcas weighing several tonnes circle, leap and tail-slap seemingly out of sheer high spirits. Highly-choreographed
There are approximately 440 species of shark worldwide, and Australia has 170 species of these sharks (The Nature Conservancy Australia, n.d.). Sharks like the Great White, usually prey on seals, dolphins, large fish, and other sharks. Only three types of shark, the Great White Shark, Tiger Shark and Bull Shark, can be lethal threats to humans (The Nature Conservancy Australia, n.d.). These sharks can sometimes be called rogue sharks. Rogue sharks are sharks that stray from feeding on their usual prey, and attack humans.
Then I think about the fish and how they must feel disgusted living in an area where people do not care about them, and that for sure if they could do anything to us they would litter on out land
Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
People even purposely catch sharks for their fins and sell them for money. Along with them being caught for their fins sharks
And last but not least, the mammals should not be kept captive because they suffer from boredom. The next time you go to a marine park think about how the animals are
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
