Maheshwar Saini answered |
Ex-situ conservation is the conservation of selected organism in places outside their natural homes. They include off site collection and gene banks.
In situ conservation, on the other hand, is the conservation of endangered species in their natural habitat. Biosphere reserves, National parks, wildlife sanctuaries and sacred groves all are examples of In situ conservation.

Understanding Conservation Methods
Conservation plays a crucial role in protecting biodiversity, particularly for threatened species. The specific method mentioned in the question involves the removal of species from their natural habitats to ensure their survival.
In-Situ Conservation vs. Ex-Situ Conservation
- In-Situ Conservation: This method involves protecting species within their natural habitats. It focuses on preserving ecosystems and their biodiversity in the wild.
- Ex-Situ Conservation: The method referred to in the question is known as ex-situ conservation. This approach takes species out of their natural environment and places them in controlled settings, such as wildlife reserves, zoos, or botanical gardens.
Importance of Ex-Situ Conservation
- Protection from Threats: Ex-situ conservation allows for the protection of species from threats like habitat destruction, poaching, or climate change.
- Special Care: In these settings, species can receive specialized care, including medical treatment and breeding programs aimed at increasing population numbers.
- Research Opportunities: These environments also provide valuable opportunities for research and education, helping to raise awareness and support for conservation efforts.
Clarifying the Correct Answer
In light of the above explanations, the correct answer to the question is not option 'B' (Biodiversity conservation) but rather refers explicitly to the practice of ex-situ conservation.
- Biodiversity Conservation: This is a broader term that encompasses both in-situ and ex-situ methods, rather than specifically describing the practice of protecting species outside their natural habitats.
It is crucial for students to understand these distinctions for exams like NEET to accurately interpret conservation strategies.

Mira Joshi answered |
Sacred groves come under in-situ conservation and represent the pristine forest patches around places of worship which are held in high esteem by tribal communities. Cutting of trees and branches is prohibited due to religious reasons. Wildlife safari parks, botanical gardens and seed blinks come under ex-situ conservation.

Mira Joshi answered |
Biodiversity hotspots are a method to identify- those regions of the world where attention is needed to address biodiversity loss and to guide investments in conservation. The idea was first developed by Norman Myers in 1988 to identify tropical forests hotspots characterised both by exceptional levels of plant endemism and serious habitat loss which he then expanded to a more global scope. Currently, 34 biodiversity hotspots have been identified most of which occur in tropical forests.

To match the correct individual with their contribution or hypothesis, let's review each person listed along with the contributions mentioned:
Robert May is best known for his pioneering work in theoretical ecology, particularly in the areas of population dynamics and stability in ecological communities. However, none of the choices directly mention these specific contributions. Among the options, the closest (though indirect) could be his theoretical work that touch upon aspects like species diversity estimations.
Alexander von Humboldt, known for his extensive work in biogeography, made critical observations on the geographic distributions of species. His work best correlates with the "Species-Area relationship," which describes how the number of species increases with the area surveyed.
Paul Ehrlich is famous for his work on population studies and environmental issues facing humanity. His statement about the planet's carrying capacity and potential biodiversity loss is widely known. The "Global species diversity at about 7 million" might closely relate to his biodiversity and population studies, though it's not his primary known work.
David Tilman is well-acclaimed for his experimental work on biodiversity and ecosystem productivity. The "Long term ecosystem experiment using outdoor plots" directly correlates with his experimental approach to studying the relationship between biodiversity and ecosystem functioning using field experiments.

Given these associations:
A (Robert May) might best fit with "Global species diversity at about 7 million" (III) though it's a rough fit.
B (Alexander von Humboldt) correlating with "Species-Area relationship" (I) is a much clearer connection.
C (Paul Ehrlich) and the "Global species diversity at about 7 million" (II) matches if we consider his general scope in biodiversity and population dynamics.
D (David Tilman) with "Long term ecosystem experiment using out door plots" (II) is an exact match for his field of work.
