ECI's mission is based on personal empowerment and
enlightenment, where people can gain a greater understanding of the vital
things in their lives. It's all about ecology and how all things are
interconnected... for all viewers and users worldwide... students, teachers,
children, adults, and the lifelong learner. Never before has this
opportunity been presented so strongly, and the marketplace has never been
more ready for it.
Plants that have adapted by altering their
physical structure are called xerophytes. Xerophytes, such as cacti,
usually have special means of storing and conserving water. They often have
few or no leaves, which reduces transpiration
Angiosperms are flowering
plants. Angiosperms are the biggest group in the plant kingdom. They have
true roots, stems, leaves and flowers. They also have seeds. The seeds are
formed when an egg or ovule is fertilized by pollen in the ovary. The ovary
is within a flower. The flower contains the male and/or female parts of the
plant. Fruits are frequently produced from these ripened ovaries.
Dr. Miller is a systematic botanist with
interests in field botany, plant taxonomy, paleobotany, education,
multimedia teaching, web design, planning and regulatory problem solving,
habitat restoration, wetland ecology, and the conservation biology of rare
plants. His present research focuses on the origin and paleobiogeography of
angiosperms
The paleoecology of global catastrophe.
Among the planet's untold episodes of climatic and ecologic disasters
(including fire, flood, glaciation, drought, global warming, and volcanism),
several events stand-out as "extinction-level" cataclysms, including the
end-Permian extinction (EPE), also known as the "Great-Dying"; the
Triassic-Jurassic boundary carbon cycle event, and the Kretaceous-Tertiary
(K-T) asteroid impact. The biotic and ecologic consequences of each global
catastrophe (including possible effects on populations of seed
plant-dwelling, phytophagous insect mutualists) will be discussed in due
course.
More than one-hundred years ago,
Darwin called the origin of angiosperms an "abominable mystery". Angiosperms
appear rather suddenly in the fossil record, with no obvious ancestors for a
period of about 80 to 90 million years prior to their appearance. Not even
fossil leaves or pollen are known from this earlier time.
The truth is that we
just don't have many early fossils of angiosperms, and those we do have are
troublesome. Many of the early fossils show a mix of features which define
modern groups, making them difficult to interpret. The implication, then, is
that there was much experimentation in the early evolution of angiosperms,
and only later did the features sort out into different lineages
Forest Trends is an international non-profit organization
that works to expand the value of forests to society; to promote sustainable
forest management and conservation by creating and capturing market values
for ecosystem services; to support innovative projects and companies that
are developing these new markets; and to enhance the livelihoods of local
communities living in and around those forests. We analyze strategic market
and policy issues, catalyze connections between forward-looking producers,
communities and investors, and develop new financial tools to help markets
work for conservation and people.

MACA
Scientific research has shown that Maca increases male and female libido.
Maca also eases menopausal symptoms such as hot flashes and and mood
swings. Millions of women already benefit from Maca and have improved
their quality of live during the menopause.
Maca increases stamina and gives extra energy. Athletes, bodybuilders and
other sportsmen are using Maca to get extra energy on a natural bases.
Maca is beneficial for men, women and children. We have listed the
advantages of Maca below:
Maca is not a medicine. It is a food supplement that works as an adaptogen;
it improves the adaptation ability of the body. It supplements the
specific needs of the body according to age and sex of the person taking
Maca. You could say that Maca fills the empty shelves in our bodies.
Maca is no invention of modern science. It is a tuberous plant that grows
high up in the Peruvian Andes. For thousands of years, the plant has been
known for its heeling and beneficial effect. But it is only in the past
fifteen years that science has taken an interest in Maca. And scientific
research has proven what the Indians of the Andes knew already for a
thousand years: it works! Ideally, you have to take two to three tablets,
evenly spread through the day. Some people may already feel the effect
after two days.
People often call Maca: Peruvian Ginseng or Natural Viagre. To avoid
misunderstandings we have made a list of differences between Maca and

Environmental unity exists everywhere, and the survival of all species
on Earth depends on its continuance. One of our objectives is to connect
space science, exploration and its discoveries with Earth, its immediate
environment and ecology, by using the media to connect people
Urban Ecology was founded in 1975 by visionary architects and activists
who believed that cities should serve both people and nature. From the
beginning, Urban Ecology has used urban planning, ecology, and public
participation to help design and build healthier cities.
Maca is a hearty root vegetable plant which grows in the high
Andean plateaus of Peru at altitudes as high as 14,500 feet above
sea level. Little is known about the origins of MACA, but the plant
is believed to have been cultivated in the Junin Plateau region of
the Central Highlands in an area called Cerro de Pasco as far back
as 2,000 years ago. The Inca's of Peru were sophisticated builders
and cultivators of the land and may have been responsible for the
cultivation of MACA which have been found in archaeological sites.
Many legends exist about the nourishing powers of MACA, such as it's
ability to promote sexual desire and increased energy. The only area
where this particular species of MACA is found is a region of
extreme weather conditions such as freezing, high winds, and
intensive sunlight. No other food plant exists in the world which
will grow at so high an altitude and survive.The
rich soil located at these high plateaus of Peru were it is very
cold and oxygen poor may account for the high levels of trace
minerals found in MACA. The Peruvian Indians of today still grow it
in the same traditional way without pesticides or chemicals. The
healing qualities of MACA have helped the local native population
thrive in this oxygen - poor plateau where they live.
The
selection of varieties of vegetables to grow should be largely influenced by
those, which form one's daily fare throughout the season. Vegetables which are
seldom purchased-unless it is because of there high price or scarcity-may not
profitably be cultivated in the home garden. But in the case of high-priced
products, then the home garden demonstrates its economic value as enabling one
to indulge in otherwise unattainable luxuries. Plainly, then, one should grow in
abundance those things of which most consumption is made. There will be a demand
for those vegetables which come earliest in spring-rhubarb, asparagus, radishes,
lettuce, and such quick-growing things; and for vegetables which may be stored
in the basement to increase the none-too-generous variety of the winter larder
potatoes, parsnips, carrots, squash, and the like. Sweet corn, beans, peas, and
beets, especially those for early greens, cabbage, cauliflower, and tomatoes,
will be indispensable summer products, which must be provided for.
Forest Biomes represent the largest and
most ecologically complex systems. They contain a wide assortment of trees,
plants, mammals, reptiles, amphibians, invertebrates, insects and
micro-organisms which vary depending on the zone's climates. Sadly, boreal and
rainforest biomes are being cut down at an alarming rate, with hundreds of
species of plants and animals disappearing from the planet on a daily basis.

The
Earth is host to more than 400,000 documented species of plant life. In turn,
our planet depends upon these plants to nurture and sustain all living
things. Plants play a critical role in the complex food web. Powered by
light from the sun, carbon dioxide from the air, and nutrients from the soil,
plants pass on this energy to the life forms that consume them. And for the
human species, plants bring aesthetic pleasure, delighting the senses with
their beauty and variety.
Botany is one of the
oldest branches of biology. It is concerned with the scientific study of
plants and other similar organisms. Within the discipline there are many areas
of study including Paleobotany (the study of plant history through fossils),
Physiology (the study of plant cells and tissues), Pteridology (the study of
ferns), and Plant Pathology (the study of diseases in plants).
