Seed-Hoarding Giant Kangaroo Rats

An ecosystem contain biological communities and abiotic factors that interact with each other. However, Introduced pest species in Australia have always been a major issue due to the unique ecosystems that have developed, undisturbed over millions of years, due to Australia's geographical isolation. This is especially evident in the introduction the European red fox in Australia, which has prompt negative changes to the population of the Long-nosed Bandicoot due to the predation by these foxes in the Field of mars and around Australia. The disruption the fox foxes have on the Long-nosed bandicoot can also result in sever cascading effects on the rest of the ecosystem, including abiotic factors like the soil and biotic factors like other native flora and fauna

Anyone looking for a new pet wants a pet that is clean, socialized and well trained. Most people don't know that these are all qualities of pet rats!

The use of animals in our generation is an incredibly large reason that our society is as advanced as it is. Without using them the way we are, police would not be able to confiscate illegal drugs or have the ability to sniff of bombs and save lives. Many people would be lost to medical mysteries without the help of lab rats, and people who suffer from mental illnesses would never find relief in the comfort of a support animal.

In the beginning, the author introduces the nutria rat also known as coypu, it was first brought into the U.S. in 1899 in California for the fur industry. These creatures now live in 15 other states including Louisiana. They were released into “Louisiana wild by state and federal agencies to provide a new fur resource and to control problem plants such as the water hyacinth (Eichhornia crassipes) and alligator weed (Alternanthera philoxeroides)” ( 1). It did not take long for them

What is it like to be a barn rat? A barn rat is probably a term that you have never

Conservation of our biodiversity not only demonstrates foresight, it protects the natural resources so vital to our own continued existence. The value of any single species to an ecosystem is immeasurable; the environment will not endure without its species, despite size or niche. These animals are not dispensable. And, they are apt to face extinction in the not too distant future, unless a resolve for their preservation is insisted by the public and enforced by governments internationally.

Everyone has different relationships with animals, s it varies between seeing them as threats or as part of the family. People believe that animals have emotions; therefore, they express happiness, pain or sadness. Since rats are worshiped by some cultures, people devote their lives to the well-being of rats. However, rats are also considered a hazard to society, so people believe they should be exterminated. Although individuals have different ideas, a balance is needed between killing and respecting the life of an animal. In order for a peaceful, balanced relationship to coexist between humans and animals, specifically rats and elephants, individuals need to respect that everyone has different beliefs on how animals are viewed throughout the world.

The articles, “Ah, rats” by John Byrne and “Chicago Is a Rat's” are about how the rat population has started to grow since 2013, because of mild winters.The article states that Chicago is the No. 1 place in the United States where rats live. Through the July of 2012, 28% more people called than in 2011 the city’s 311 center asking for crews to come out and get rid of these annoying pests.I feel, that rats and other rodents are a threat to the Chicagoland area, because the pests carry various diseases and potentially start a plague or an epidemic.A main point was that since Chicago is so densely populated it means that there is a higher percentage chance for unsanitary streets in the city which will result in more rodents and vermin crawling

After examining a food item, fox squirrels either cache or eat it, frequently moving to a locality away from the source of food. These squirrels begin the process of caching with digging. They then tap the nut with their front teeth to fix it more firmly in the ground. On the first day of observation, the fox squirrel ran away quickly once it saw me and took refuge in a tree. This conduct shows that these animals take advantage of their maneuverability and agility in the trees to flee their predators. They also produce alarm calls that probably alert other squirrels when they are

My topic for my research paper is Nutria Rats and what has come from them being in Louisiana. I plan to make many points throughout this essay including, how and why they ended up in Louisiana. The sources at I have accumulated over the past week to build on each other and provide me with facts and information that I was unaware of prior to doing this research. The following source will be used throughout my research paper whether it is basic knowledge or facts given from these articles.

The first article chosen to review is ‘Population dynamics of house mice in Queensland grain- growing areas, 2013, Wildlife Research, 40, 661–674 by Anthony Pople, Joe Scanlan, Peter Cremasco, and Julianne Farrell’. This article focuses on the population field mice in the Darling Downs. This region of Australia is an extremely arable district in south eastern Queensland that has lost the majority of its native vegetation cover to agriculture (Fensham and Fairfax, 1997). The theme of this ecological topic demonstrates how a population of a species can increase due to the availability of food, and the methods to reduce numbers via poison baiting.

“Some homeowners are being invaded by mice and field rats which are thriving in the burned-out areas recovering from the wildfires, in part because there are very few predators,” Bauer said. “And with the regrowth of vegetation, the rats and mice have had an ample food source and

The mongoose failed to remove the black rat population was because of how its a predator to similar animals as the black rat. Yes, the problem was solved as the mongooses sometimes caught the rats, but like I said before they were predators to the same animals and reduced the population for them even more, which was a problem that the hawaiian plantation owners were trying to solve. This was proven in paragraph seven when it was stated that ¨It's not that the mongooses became friends with the rats. They still ate a bunch of them. But mongooses are not too different from most other animals: they go for the easy meal. ¨ This was explaining how they did solve part of the problem, but for the most part just added to it and made it worse.

Rats were the cause of a disease called ‘The black death’ also known as the bubonic plague, this disease killed over 1,500,000 people in England, this shows that they were a major issue due to the infectious diseases they carried (killing many people). It was also stated that even gravediggers died as for this infection. A reason that this was a big concern was because during the 14r​h ​century, people didn’t have good medical knowledge meaning that people with the disease were most likely going to die. Another dispute caused by the rats is that if people caught the virus, they’d be badly infected meaning that they couldn’t go to work or any job which leads to no income

These scientists that use animals in their research attempt to use rodents rather than companion type animals. It’s said that rodent brains are built like a human brain, so it works out just fine. The only downfall is that sometimes the rodent brain isn’t compatible enough for a certain medication. In that case, the scientist test the remedies on a monkey. Scientist do this to make sure the drug is safe and efficient before
