Introduction Nature has gifted India with many biodiversity hotspots that are enriched with notable flora and fauna. Out of a total of 36 hotspots of biodiversity in the world, four are officially located in India which are the Himalayas, the Indo-Burma region, the Sundaland, and the Western Ghats. To this list, we may add Sundarbans and the Terrai- Duar Savannah grasslands to make the count six. Here are the descriptions of these six biodiversity hotspots of India. The Himalayas When one goes northwards in India, up the Himalayas, he/she will see a notable climate change along with a continuously diverse ... Read More

Introduction Trematodes are parasites that live in various organisms’ bodies including human beings. They can be divided into more than 20, 000 species some of which are associated with parasitic infections in humans and animals. This tutorial offers a snapshot of what trematodes are, how is their body organs, and how they reproduce and grow. Examples of trematodes and some infections they cause have also been included. What are Trematodes? Trematodes are a class of parasitic leafworms. They are also known as flukes and they are linked mostly to aquatic fauna such as mollusks and fish. Trematodes also infect vertebrates ... Read More

Introduction India has mega diversity in terms of biogeography. India has only 2.4 % of the area of land in the world but has 8% of the biological diversity of the world’s content. India is divided mainly into 10 biogeographical zones. These are - Trans-Himalayan Region Himalayan Zone Indian Desert Zone Semi-Arid Region Western Ghats Deccan Plateau Gangetic Plain North East Region Coastal Region Andaman and Nicobar Islands. Biogeographical Zones of India The 10 most vibrant biogeographical zones of India are as follows − Trans-Himalayan Region This region covers 5.6% of the Indian geographical area. The trans-Himalayan ... Read More

Introduction− What is an Ecosystem? An ecosystem consists of both living or biotic and non−living or abiotic beings. The biotic and abiotic factors remain in constant communication with and are dependent upon each other for survival. It has been observed that living beings interact with the environment in which they exist. The living beings and their environment create an ecosystem. It contains both biotic and abiotic factors. Biotic factors are the living beings while the nonliving beings are called abiotic factors. Image 1: Types of Ecosystem There are various types of ecosystems in the world in terms of ... Read More

Introduction: What is a Food Web? A food web is made up of all the food chains in a single ecosystem. Each living thing is part of multiple food chains in the given ecosystem. Each food chain is one probable way that energy and nutrients may take as they go through the ecosystem. All of the food chains are interconnected and overlapping in nature. These overlapping food chains in an ecosystem make up a food web. Each food web consists of three constituents known as trophic levels. The first trophic level is producers that produce foods. Then second ... Read More

Introduction Environmental resistance is a process of controlling the population of species in an ecosystem. Nature usually stops the overgrowth of population and this is seen in all ecosystems of the world. The idea of environmental resistance is to keep the ecosystems balanced. This tutorial discusses various ways, examples, and definitions of environmental resistance. What is Environmental Resistance? Environmental resistance refers to the environmental process of stopping the overgrowth of the population. Usually, if there is no resistance to the growth of the population of a species it will grow uncontrollably, threatening the balance of an ecosystem. Therefore, natu8re employs ... Read More

Introduction The rapid growth of the human population and urbanization is driving the extinction of many species of animals in India. According to a 2020 study, more than 500 animal species on earth are on the verge of extinction and many of them are from India. Here are the nine most endangered species of animals that are threatened for survival in India. What are Endangered Species? Endangered species are the species that have a threat of extinction. If proper conservation methods are not applied, they may vanish from the planet. These species are available but their survival is in ... Read More

Introduction In simple words, surface water is that water which is found above the surface of the earth. Examples of surface water include water from seas and oceans, rivers, and ponds. Groundwater is found below the surface of the earth. This water is found at groundwater tables, soil pore spaces, aquifers, and rock fracture points. In the case of surface water, the nature and type of some chemical contaminants can be verified without chemical tests. Even though 98% of all freshwater in the world is groundwater; however, it is important to test the purification levels of groundwater before consumption as ... Read More

Introduction Plant species may respond to variations in environmental conditions. Many plant species can alter their leaf morphology in response to changes in environmental conditions. This phenomenon is known as heterophylly and it is widespread among land plants. In many cases, heterophylly is an adaptive mechanism that permits plants to respond to environmental heterogeneity. Recently, many studies and research have been done to investigate the occurrence of heterophylly in various plants. Many studies have found that heterophylly in plants is a result of the action of phytohormones. Plasticity is the manner in which plants follow various pathways in response ... Read More

Introduction- What is Biodiversity Loss? Loss of biodiversity or biodiversity loss refers to declining biodiversity within a species, a chosen geographic area, an ecosystem, or Earth as a whole. Biodiversity refers to the number of genes, and individual organisms within a given species, species, and biological communities within a defined geographic area, that ranges from the tiniest ecosystem to the global biosphere. Biodiversity loss is a term used to mean the decline in the number, genetic variations, and variety of species, and various biological communities in a given area. Such a loss in the variety of life and ecosystem ... Read More
