1. The Volga River
The Volga River is a riverine located in Europe, Russia in a federal subject of Russia, Astrakhan
Oblast. Its direct location is Longitude: 45°50′30″N Latitude: 47°58′17″E. Volgograd and Nizhny
Novgorod are important cities on the bank of the Volga. The Volga River is the largest river in
Europe in terms of length of length, discharge, and watershed. It starts in the Valdai Hills of north–
western Russia and flows approximately 3,685 km before creating this delta and pouring into the
Caspian Sea. The Volga River also contains a wide variety of flora and fauna. The river is split into
4 different sections: upper, middle, lower and the delta. The Volga basin is divided into four major
sections, including the Upper Volga, Middle Volga, Lower Volga, and delta. The delta is within the
Volga Delta–Northern Caspian Drainages ecoregion and had a length of about 160 km.
The Volga River is under investigation because dams upstream have altered the natural flow regime
of the river. Another reason is the mass amount of fishing and lastly the river is under investigation
because of the poor water quality.
The Volga River had its beginnings in the glacial Valdai Hills (225 meters above sea level), which is
located near Moscow in the northwest. During the 13th century, the southern part of the Volga River,
below Nizhny Novgorod, saw the invasion of Mongols, whose influence is evident in cities like
Astrakhan and Kazan. Along with the establishment of cities, dams and reservoirs, the

Short face but longer skull which had centralized eyes.
The most dramatic change between Eohippus and Orohippus was in the teeth: the first premolar
teeth were dwarfed. The ridges became more noticeable on the teeth.
Both of these factors gave the Orohippus greater grinding ability, suggesting it consumed tougher

Ethiopia is plagued by constant drought, robbing canals communities and most importantly crops of
their water. Thus, making water very valuable and precious to remote farming communities. Second
to drought is soil degradation and erosion. This is caused through the overgrazing of livestock,
deforestation, lack of rest and poor farming practices. Soil lacking nutrients make plants hard to
grow and are essential to maintaining a healthy crop. In addition, the loss of wild biodiversity, the
loss of food crop genetic diversity and climate change are all factors in contributing to
environmental constraints in the food security of Ethiopia. The lack of water in canals and rivers due
to drought causes strife all through out Ethiopia as water is vital to grow crops. Farmers further up
the canal or rivers over use the water leaving next to no water for farmes further down the canal/
river. Contamination of soil and already rare water makes things even worse, increasing crop failure.
The emergence of new pests and diseases among crops is not an uncommon thing throughout
Ethiopia. However, the pesticides used to protect crops are having side on affects with the natural
wildlife of Ethipoia. Many authentic species are dying through the use of pesticides.
There are numerous constraints that affect the development of crops grown in Ethiopia that are not

Bioregionalism gives the large–scale geographical boundaries to determine an area, such as the

at the local level" (Evanoff, R., & O'Neil, E.). Evanoff and O'Neil prove societies strive more when
they are divided by their natural barriers. Determining the bioregion of an area allows us to know
our watersheds, soil type(s), and mountain ranges. Bioregions are important because it allows us to

Summary:
The international trade in corals today mainly focuses on live corals for the marine reef aquarium
trade. The purpose of this study is to understand the overall trends over time (in this instance, 21

has an enormous impact on the species, as it can lead to fragmentation in the species, meaning the

When vehicles roam where they are not supposed to, they are potentially destroying the delicate
habitat of the desert tortoise. This loss of habitat leads to a decline in species numbers. For example,
"the number of desert tortoises has decreased by 90% due primarily to human activity" in select
areas of the Mojave Desert ("Threats to Mojave"). While a loss and decline of one species in the
desert may seem insignificant, the potential loss of the desert tortoise would be devastating to the
ecosystem. All organisms in an ecosystem play a specific role, and when an organism is removed,
that act alters the entire ecosystem.
Finally, the desert tortoises face threats through camping, shooting, and other human activities. With
these activities comes the "threats associated with increased human presence" ("Threats To Desert
Tortoises"). These threats include loss of habitat due to the development of recreational facilities,
mishandling and disturbing tortoises, killing of tortoises on roads, and the destruction and
degradation of vegetation. All of these threats lead to a decline in the tortoise population, which does

This is a great question that is easily answered. Many economist have been prone to saying that
mining, whether near lakes and rivers or not, is the single greatest industry for the economy and
should not be stopped for any reason whatsoever (International Council of Mining and Metals).
While this statement is true in the fact that the economy revolves around mining, or at least the
result of mining, it is false that mining should take precedence over natural resources. Statistically
speaking, is was found that the mining industry, both directly and indirectly, employed 1,903,440
people in 2012 (National Mining Association). That same study found that mining industry paid
around $45.8 billion in taxes that same year. These facts alone are what the opposition presents as
the reason mining should not be regulated, and definitely not stopped all together in a particular
region. While the economic positives that mining bring to the table are undeniable, what it comes
down to is protecting that land we take from. Scientists have been saying for centuries that we will

Progesterone is a steroid hormone most commonly found in the female reproductive cycle. The
following diagram represents three feedback loops for the menstrual cycle. The blue feedback loop
shows two hormones, FSH and LH, secretion as to begin the growth of the follicle then the
hormones work together to start the estrogen secretion the estrogen then has a negative feedback
from FSH causing it to stop been desecrate. The red feedback loop shows, increased levels of
estrogen occur midpoint in the cycle causing positive feedback to respond on the LH cells in the
pituitary. As LH levels rise ovulation will occur. The purple feedback loop concludes after ovulation
and shows the follicle cells transform into corpus luteum which secrets then builds up progesterone
and estrogen levels forming the endometrial lining the hormones work together and a second
negative feedback signal is sent to allow the release of FSH and LH. The corpus luteum then
deteriorates dropping the production of estrogen and progesterone allowing menstruation to occur.

41. Human Impacts Toward Soil Biodiversity
METHODS
Data Collation
Data was collected from published studies or in–press studies that focused on human impacts toward
soil biodiversity. Potential relevant studies must compare multiple sites which having different land
use type and/or intensity. In addition, species abundance, richness, occurrence, or other diversity
metrics must be present in the study, so that diversity can be estimated. Furthermore, the information
of the sites location is also very important, studies which have the sites coordinates are more
preferable. The coordinates are very useful not just to pinpoint the exact location on the map, but
also to help us acquire other information, e.g. climate, biome, and ecoregion (all paper criteria
similar to Newbold et al. 2015). To find these potential relevant studies, I used Web of Science
(http://webofknowledge.com/) and Google Scholar (http://scholar.google.co.uk) as the search engine
with "soil invertebrate", "land–use", "pitfall trap", and "ground invertebrate" as my search term.
The corresponding authors of the suitable studies were contacted, asking whether they are willing to
share their raw data (which were not usually made fully available in the paper or supplementary

creatures from plastic and or human waste of some form and in some cases this could be prevented
just by recycling. Another conservation ethic that is needed quite dearly involves lessening our
overall water consumption. States such as California and Nevada have been experiencing water
shortages do to droughts, and who is to say that this cannot happen worldwide if proactive measures
are not acted upon. From taking shorter showers to turning off the water when you stop to brush
your teeth can really help make a difference. I myself as well, have many different conservation
ethics that I live my life by. For example, plastic is abundant enough on the landscape, so I avoid
buying bottled water and stick to filtered tap water. I as well monitor my water usage and recycle

Red Wolves have no natural predators. The Red Wolves have been endangered since the 1960s,
which has affected history and the environment ("Red Wolves–History"– Red Wolves Conservation
Center). The red wolf's main threat is breeding with the eastern coyotes, but can helped by having
specialists set up camp to breed red wolves together. The Red Wolves, which are also known as the
Canis Rufus, are the world's most endangered canid (Red Wolf Habitat). The length of a red wolf is
four to five feet, weigh from fifty to eighty pounds, and a height of about twenty–six inches. Their
fur is black and brown on the top of their body and yam (brown, orange, red) on the stomach area.
These beautiful creatures live in swamps, forests, and coastal prairies from Southeastern Texas to
Central Pennsylvania. Canis Rufus hunt and live in a pack of five to eight. In the pack, there is an
alpha wolf, which is a wolf which breeds adult duplets and progeny. Wolves are known to only have

Red Wolves are originally from Southeastern USA. Because of habitat loss and the control predator
programs, red wolves, that were left, migrated to the Northeastern part of USA. Which was harmful
to them, because of the vast populations of coyotes in Northeastern USA. The incorporation of small
Red Wolf population, vast Coyotes population, and small area causes the two species to interbreed.
This interbreeding causes the breakdown of natural barriers ("Red Wolves and Coyotes" USFWS).

As a result, the biodiversity of freshwater species is seriously affected by climate change.
Not only the marine environment and the freshwater communities, but the terrestrial species are also
impacted by climate change. The number of plant species has been decreasing. Prowse et. al,
(2009b, p.284) report that temperature and precipitation change will lead to the change in the
composition of flora communities, and this can result in the loss of plant species. Also, Lemieux
& Scott (2005, p.393) state that there is a wide decline in the taiga biome, thus, the global
warming directly impact the biodiversity of plant species. Climate change can also influence the
birds ' growth rate as well. Lower birds ' growth rates and adult body mass occurred in the north

well. According to the report from Prowse et. al. (2009b, p.285), owing to global warming, the
incidence of parasitic infection happens more frequently and the forage has been decreasing in
winter; these trends result in the decline in numbers of caribou. Moreover, the impact of climate
change on the permafrost seems to be serious. Discontinuous permafrost will disappear at the
southern boundaries of these permafrost zones, and the continuous permafrost will degrade to the

without definite residence but migrate across the ice and through the seas from Russia to Alaska,
Canada to Greenland and onto the Svalbard archipelago. Adequate food and energy are the key for
polar bear to survival in the harsh arctic environment. In recent years, however, the polar bears have
faced enormous challenges in arctic, where they have no natural enemy. It is well known that the
normal temperature of human body is around 36.5 degree centigrade, sometimes, sudden illness
causes a rise in body temperature. Every sudden increase in temperature of human body is a threat to
human health. The same is happening with the global climate system. On the surface, the
temperature is just a fraction of degree centigrade but the air temperature can be changed very
severe during a certain period and it also causes a chain reaction of weather and climate. The
Intergovernmental panel on Climate Change (IPCC) reports that since the industrial revolution, the
average temperatures of Earth surface has risen by 0.6 degree centigrade (Lisa V. Alexander).
Moreover, the rise in temperature is concentrated in recent decades, there has been an upward trend

59. Desert Desert Environment
The deserts of central Australia make up a unique ecoregion. As it may be properly assumed, an arid
desert environment is not easy to adapt to. Many different species, including birds, reptiles,
mammals, and various plants are able to thrive in such conditions. Human impacts on the island
continent have interrupted the success of some of these species. One group of species that have been
very negatively impacted by human interaction are small digging mammals. These mammals are
typically small and almost rodent–like. Although small, digging mammals, such as Macrotis lagotis
(the Greater Bilby), have a large impact on the vegetation biodiversity of the ecoregion. They use
their front paws to dig into the ground while they search for food. In the process, diggings capture
organic matter, provide habitat for a diversity of microscopic and macroscopic organisms, and
increase nutrient cycling. Diggings also capture plant seeds, increasing seedling germination,
recruitment, and plant growth. The overall effect of mammal diggings is therefore increased plant
vigor and resilience, increased biodiversity and consequently improved ecosystem functioning
(Fleming et al 2014). Due to various impacts by human, these small mammals have quickly been
declining. The large impact humans have had on the small mammals is the introduction of invasive
species. Felis catus (feral cat) and Vulpes vulpes (fox) are overpopulated invaders who prey on

61. Great Victoria Desert Analysis
Nearly all–large deserts are found away from the coasts, in areas where the oceans moisture rarely

However, not all deserts may be sandy and hot, they do have one thing on common...they are dry.
One type of desert we are focusing on, are the subtropical deserts, which sand dunes are a typical
feature, along with the low vegetation and scarcity of water (KDE). Subtropical deserts are the
hottest deserts, which are dry in the summer and cooler but still dry during the winter (Nature
Works, 2015). In fact, most deserts receive less than 300mm of water a year (Paleontology U, 2013),
much like the Great Victoria Desert in Australia where annual rainfall ranges from below 150mm to
over 250mm (Fund, 2014). Great Victoria desert is the largest desert in Australia ranging to about

The Effects of Global Warming on Polar Bears
Introduction
Global warming is the recent and ongoing rise of temperature on a global scale. Over the past
century, the Earth's average temperature has risen 1.4°F (Carlowicz, 2010). Global warming is the
effect of an excessive amount of greenhouse gases in the atmosphere. Greenhouse gasses trap heat
from escaping back into space to keep the Earth from freezing, this is called the Greenhouse Effect.
An excessive amount of greenhouse gases in the atmosphere trap too much heat, thus, causing
Earth's temperature to rise. The Earth's rise in temperature is melting ice in its colder regions. Many
animals who live in the Arctic Circle, the lands surrounding ... Show more content on

The melting sea ice is also affecting the polar bear's main prey, seals, forcing the bears to turn to
alternate, less nutritious food sources. Once sea ice forms in the winter, seals use the ice to create
dens to give birth to their pups. In these months, polar bears use sea ice as their hunting grounds to
find seal dens. Now that Seasonal Ice is forming later and melting earlier (IPCC, 2013), seals have
less time to build dens and give birth. Consequently, polar bears have less time to hunt their
preferred prey of seal pups. They must spend more time on land hunting other animals of less
nutritional value. Organizations like Sea World Parks have reported male polar bears occasionally
eating newly–born polar bear cubs because they cannot find other food to eat. Lack of nutritional
food leads to a reduced body size. Polar bears are becoming thinner and weaker from not eating
enough (Rode, Amstrup, & Regehr 2010). They have to swim longer distances to find ice to hunt
upon, causing many cubs to die because they are not yet strong enough. In the Hudson Bay, the
average polar bear weight has decreased by 15% and the population has decreased by 20% (National
Wildlife Federation). In the summer when there is no ice, polar bears in the Hudson Bay go onto

ecoregion made up of 2 terrestrial ecoregions; Borneo Lowland rainforests and Borneo Montane
rainforests. This environmental impact report is focused on the Borneo Lowland Rainforest. The
Borneo lowland rainforest is located in South–East Asia and routes through parts of Indonesia and
Malaysia, and is also located north of Australia. It includes a large diversity of habitats such as, large
areas of karst (barren limestone plateaus with caves, sinkholes, and gullies), and a high–altitude
swamp forest.
The Borneo lowland rainforests are defined as the areas that lie around mountains and below their
level. Borneo lowland rainforests contain 10,000 plant species, 380 bird species and 15,000
mammal species. There is no distinct 'borders' that would outline Borneo's Lowland Rainforests, but
an approximate estimate suggests the total area being around 420,000 km2. From those statistics it is
estimated the lowland forest takes up around 57% of Borneo's total land. It lies within the tropical
monsoon climate zone. The Borneo Lowland Rainforest is evidently a rainforest. Its features include
a stable climate throughout the year with a huge amount of rainfall, with the monthly rainfall being
