Biodiversity and conservation: Endangered species, hotspots, extinction

Biodiversity is important to humans for many reasons. Biodiversity is also considered by many to have intrinsic value—that is, each species has a value and a right to exist, whether or not it is known to have value to humans. The biodiversity book by the Commonwealth Scientific and Industrial Research Organisation describes 5 core (and interacting) values that humans place on biodiversity: Economic- value of biodiversity […]

Ethical and Moral value refers to the principles that humans should abide by to maintain a healthy relationship with the coexistence of various species on the planet. Biodiversity, as the name itself suggests, is the diversity of life. It is all the living matter we see around us – plants, animals, microorganisms, fungi, etc. All

When a species is listed as endangered, it means that it is extremely likely to become extinct in the near future, either globally or within a certain political jurisdiction. Endangered species may be threatened by a variety of circumstances, including habitat degradation, poaching, and the introduction of invasive species. The International Union for Conservation of

In a surroundings with no past existence, such as a barren habitat, primary succession takes place. A disruption, such as a wildfire, causes secondary succession in an area that was earlier inhabited. The colonisation of a new habitat that is devoid of creatures and plant life is known as primary succession. Secondary succession is the

Despite various pieces of research on life on other worlds, it has been determined that Earth is the only planet where live organisms can be found. Survival necessitates unique types of atmospheres, land formations, and ecosystems found only on Earth. Each continent on the earth has a desert and its own ecology, which is referred

There has been considerable diversification of living forms on Earth since life began almost 3.8 billion years ago. The term ‘biodiversity’ refers to the overall amount of diversity found in all levels of biological organisation. Conservation of biodiversity is critical for economic growth and poverty alleviation. The vast majority of the world’s poor live in

Introduction The concept of species and taxonomic hierarchy helps in describing the organisms in terms of their characteristics. This allows the grouping together of organisms that have plenty of similarities. Taxonomy, in particular, is a Biology branch that facilitates the classification of living things. Developed back in the 18th Century, the branch is relevant today.

Introduction A species is a basic unit of classification. However, the concept of species is not so easily defined. Species are the central unit of comparison in all fields of biological study from behaviour to anatomy and from  ecology to morphology; fields like evolution, physiology, genetics and paleontology all make use of the species as

Introduction Cockroaches are insects that crawl on surfaces that are not exposed to sunlight. Most species of cockroaches are as big as a thumbnail. The most common cockroaches found in India are glossy, brownish-black in color. They also have a pair of wings and three pairs of legs used to crawl on surfaces. They have

Introduction The Classification of biodiversity is the shortened version of biological diversity and the successor of the term biotic diversity. It was first published after a symposium held in 1986. It means the sum of all the variety of life forms found on planet Earth. This term was coined to define the value assigned to
