Importance of Water Caltrop – Trapa nutans
Singhara is known as the Water Caltrop in English. In Botany it is known as Trapa nutans. Its other two species are Trapa bicornis, and Trapa rossica. The later is an endangered species.
Positive and Negative Interdependence among Organisms in Ecosystems
Interdependence between two species through which individuals of either one or both species benefit is called positive interdependence. The benefits to the individual of any species through this relationship may be continuous or transitory, obligate or facultative. Both partners in this type of relationship may be in close contact; one may be inside some specific area or attached to the surface of the other’s body. Positive interdependence is divided into three major types: mutualism, Commensalism, and proto-cooperation.
Medicinal Weed Argemone Mexicana or Satyanasi
Medicinal weed Argemone Mexicana or Satyanasi is a prickly weed. It has been introduced and naturalized in India. It grows as waste land weed in almost every part of the country. It is reported as crop weed also in many parts of the country.
Various Important Alternatives to Deforestation
Deforestation contributes up to 20 percent of greenhouse gas emission which is more than the combined emission by all the cars, trucks, planes, boats and, trains of the world. Deforestation threatens our climate. Besides this, it threatens the livelihoods of 1.6 billion people who depend on forests for food and economic activities. They serve as habitats to rare and so far, undiscovered species of plants and animals. They also play a key role in maintaining water cycles and preventing floods and soil erosion. Hence, forests across the world need urgent measure of protection by all possible ways, may it be through alternatives to deforestation.
Pollution- disruption of nutrient cycles and habitats
Our natural resources are known to have some specific qualities of their own. These qualities are known as natural qualities. It is due to specific natural qualities that different natural resources have been useful to us and to the whole biosphere. But now, the condition has changed considerably. Most of our natural resources like air, water and soil have gone bad due to pollution of different types. What is pollution?

Conservation and Management of Forest
A forest is a highly complex and constantly changing environment. It is made up of a variety of living things like wildlife, trees, shrubs, wildflowers, ferns, mosses, lichens, fungi and microscopic soil organisms; and non-living things such as water, nutrients, rocks, sunlight and air. Trees are the biggest part of this complex community.
What is Ecosystem? What are its components?
The environment of our earth has a number of life zones that support birth and development of all types of organisms.
All the life zones of the earth are collectively called as Biosphere.
The biosphere vertically extends into the atmosphere up to about 10 km and downwards into the oceans up to a depth of about6.9 km.
Fern species that grow on old walls in
Ferns belong to Pteridophytes and grow on high altitudes in moist cold places. These don’t need any fertile soil. Since Ranchi or the most part of Jharkhand is located on high land its climate is rather different and somewhat similar to those area of mountains. The author reports here the two fern species that preferably grow in this region that too on old walls.
Plants that survive under hardships
Many ferns grow along north or west facing walls every year. Their spores might have been there in crevices during the dry season. Unless there is a supply of water from leaking pipe they complete their life cycle within the rainy season and pack up with the passing rains. They pass away and leave for us a lesson to remain happy and survive in hard conditions.
Human Reproductive Health
The physical and mental conditions that collectively affect the reproductive capacity of a male or a female are called as reproductive health. The reproductive health is most essential for reproduction.
