Non-Native Specie House Mouse3a). The house mouse is a native r.docxhenrymartin15260
Non-Native Specie: House Mouse
3a). The house mouse is a native rodent from Eurasia. They were introduced worldwide through the human association. The first country that introduced the house mouse to the United States was Western Europe. In Southern California we don't have a high population of house mouse but the small amount that we do came from Asia.
3B). This specie does have a colonized habitat. They like to colonize in homes, stores granaries, barns, and feed houses. They like to colonize in humans homes because they eat any type of human food but they are mainly on the look out for cereals and grains. when they have to set up a nest they go out to the wild specially on greenery areas and fields. The House mouse don't have loss of natives since they aren't aggressive species since they habitat in large territories. The male house mousse get aggressive male to male because they like to protect their territories. when female mouse are expecting they get aggressive with female mousses when they are out looking for food.
3C). yes house mouse to have resources because they are on the look out for food so that means their resources are homes mainly because they will always find food. since they are nocturnal specie they can inhibit in close places.
3D). there isn't much of a bad impact for the native species since they mainly inhibit in hidden territories. They like to nest out in the wild but they have their own way of going in and out of their territory to prevent from being invaded by others.

Native species refers to animal or plant species thriving in the ecology they evolved from, where exotic species refers to plant or animal species living outside their ecological zone, which existence in the present ecology is as a result of human activity. Ecology on the other hand refers to interactions between the living organisms and their environment. This means that, there is usually a change in interaction when a new species is introduced in a new ecological system. The change in interaction affects both the introduced species and the indigenous species. The term exotic species culminates from European exploration, colonization and settlement outside their continent. They carried with them plants and animals originally thriving in their original homeland to their new settlement areas.
This paper focuses on animal species that can be found from Canada to South America and, in the United States, from the East Coast to the Great Plains and New England. Cottontail r.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. Biome
The suborder of Folivora
is the name for six
species of sloth, which
include four species of
three-toed sloths, and
two species of two-toed
sloths. They live in the
tropical rainforests of
South America and
Central America.
4. Food Web
Sloths mostly eat
leaves, but also eat
some insects and fruit.
Their main predators
are the harpy eagle and
the jaguar. The majority
of sloth deaths however
are caused by humans
through activities such
as poaching.
5. Competition
A sloth’s main source of food
are leaves, usually from the
Cecropia tree, and because of
this they do not have any real
competition for food, as the
leaves are in high supply in the
rainforests where they dwell.
Sloths will usually pick a single
tree where they will eat, and
sleep, as well as defecating at
its base, however the
abundance of Cecropia trees
means there is not territorial
competition between
individual sloths.
6. Biodiversity
The sloths of the Folivora
suborder are part of the
order Pilosa. This order also
includes the suborder
Vermilingua, which contains
several species of anteater.
Its next closest ancestor is
the armadillo, which is in the
order Cingulata. Together,
the Pilosa and Cingulata
orders form the Xenarthra
superorder.
7. Adaptations
Sloths have a variety of adaptations that help
them to survive. A physical adaptation is that
their fur grows in the opposite direction of
normal animals, which provides protection for
the sloth when it is hanging upside down from
a tree. It also camouflages them to hide them
from possible predators. Their claws are also
long and sharp to allow them to easily climb
and hang on branches. A physiological
adaptation of the sloth is that they maintain
very low body temperatures of between 30-34
C°. As the leaves that they eat contain few
nutrients and are tough to digest, they have
also developed large stomachs that can take
over a month to digest all their food. A
behavioural adaptation of sloths is that every
week they will descend from their tree to
defecate at the base of it. The feces will help
nourish the tree where the sloth finds its food,
allowing the tree to provide more food for the
sloth in the future.
8. Evolution
The common ancestor of all sloths, including
ground sloths, first emerged approximately 60
million years ago during the Paleogene. Since
then, there have been five families of sloth :
Bradypodidae, Megalonychidae,
Megatheriidae, Mylodontidae, and
Nothrotheriidae. Today, the only extant
species are in the Bradypodidae and
Megalonychidae families, with all the other
species being extinct ground sloths. The
family Bradypodidae contains four species of
three-toed sloths, which are the pale-
throated sloth (Bradypus tridactylus), the
brown-throated sloth (Bradypus variegatus),
the maned sloth (Bradypus torquatus), and
the pygmy three-toed sloth (Bradypus
pygmaeus). The family Megalonychidae
contains two species of two-toed sloths,
which are Hoffman’s two-toed sloth
(Choloepus hoffmanni), and Linnaeus’s two-
toed sloth (Choloepus didactylus).
9. Adaptive Radiation
Today’s two-toed and three-toed
sloths have several differences from
their common ancestor that allow
them to inhabit different niches,
other than number of toes. This
common ancestor lived about 35-40
million years ago. Two-toed sloths
have six cervical vertebrae, whereas
three-toed sloths have nine. Three-
toed sloths also have tails and longer
forearms, and two-toed sloths have
shorter necks and larger eyes. The
main thing this has changed between
the two types of sloths is that the
three-toed sloths tend to stay and live
in a single tree, whereas the two-toed
sloths will move through different
trees more often.
10. Primary And Secondary Succession
Sloths will only inhabit a
certain area if it contains the
right trees to sustain them. If
the trees where they find
their leaves are destroyed,
for example because of
deforestation, the sloths will
be unable to survive. If
however, primary or
secondary succession occurs
in an area near a sloth’s
current habitats, and the
required trees begin to grow
there, the sloth may be able
to survive in that new
habitat.
