☑️ Are Decomposers are part of keystone species ?
👉Generally NO.
Decomposers are not considered keystone species.
✨Why?
A keystone species is one whose impact on the ecosystem is disproportionately large relative to its abundance.
Examples: sea otter, starfish (Pisaster), beaver, African elephant, etc.
Where do decomposers fit?
👉Decomposers (fungi, bacteria, some insects) are absolutely essential for nutrient cycling.
👉But they are not usually classified as “keystone species” because:
•They are a large group, not a single species.
•Their function is broad and continuous, not a specific ecological “keystone” role.
•Keystone species usually have a controlling influence on population dynamics or ecosystem structure.
However…
👉Ecologists sometimes describe decomposers as “functional keystones” or “keystone processes”, meaning:
•Nutrient recycling is a keystone process.
•Not that decomposers themselves are individually keystone species.
Therefore it is safe to say. 👇
☑️Decomposers are critical for ecosystem functioning, but they are not typically categorized as keystone species.
Keystone species are specific species whose removal leads to ecosystem collapse, while decomposers represent an entire functional group performing a keystone ecological process (nutrient cycling).

Q.1857) Snow Leopards display which features?
1.Crepuscular activity pattern
2.Extremely long tail aiding balance
3.Territorial marking using scrapes
4. Living in large social groups
Correct Answer: a) 1, 2 and 3 only
Explanation:
Snow leopards (Panthera uncia) show the following characteristics:
1. Crepuscular activity pattern — TRUE
Snow leopards are primarily crepuscular, meaning they are most active during dawn and dusk.
(They can also be cathemeral depending on prey availability, but crepuscular is correct.)
2. Extremely long tail aiding balance — TRUE
They have a very long, thick, furry tail (almost as long as the body) which:
•Helps in maintaining balance on steep cliffs
•Provides warmth when wrapped around the body
3. Territorial marking using scrapes — TRUE
Snow leopards mark their territories using:
•Scrapes (scratching the ground)
•Scent marking
•Urine spraying
•Rubbing objects
Scraping is a well-documented behaviour.
4. Living in large social groups — FALSE
Snow leopards are solitary animals.
Only mothers with cubs stay together; otherwise adults live and hunt alone.

Q.1858) Consider the following statements regarding the Swadeshi movement (1905–11)
1. For the first time, the idea of passive resistance received systematic theoretical justification.
2. It saw the formation of the first all-India labour federation.
3. It marked the first national-scale boycott of both foreign goods and government institutions.

Q.1858) Consider the following statements regarding the Swadeshi movement (1905–11)
1. For the first time, the idea of passive resistance received systematic theoretical justification.
2. It saw the formation of the first all-India labour federation.
3. It marked the first national-scale boycott of both foreign goods and government institutions.
Correct Answer: b) 1 and 3 only
Statement 1: “For the first time, the idea of passive resistance received systematic theoretical justification.”
During the Swadeshi movement, Aurobindo Ghose and Bipin Chandra Pal provided a systematic ideological foundation for passive resistance, which included:
•Non-payment of taxes
•Boycott of government institutions
•National education
•Swadeshi industries
This was the first structured theoretical articulation of passive resistance in India.
Statement 2: “It saw the formation of the first all-India labour federation.”
The first all-India labour federation was AITUC (All India Trade Union Congress) formed in 1920, long after Swadeshi movement.
Before that, labour organisations were local or sector-specific (e.g., Bombay mill workers, Calcutta jute workers).
Thus, the Swadeshi movement did NOT see the formation of a national labour federation.
Statement 3: “It marked the first national-scale boycott of both foreign goods and government institutions.”
The Swadeshi movement was the first truly national movement (though strongest in Bengal) involving:
•Boycott of foreign cloth, sugar, salt, goods
•Boycott of government schools, courts, councils
•Use of Swadeshi goods
•Establishment of National Schools and Colleges
Earlier movements did not have such a nationwide, organised boycott programme.

☑️CRITICAL TIGER HABITATS (CTH)
(Also called Core areas of Tiger Reserves)
1. Legal Basis
Critical Tiger Habitats are notified under:
➡ Wildlife (Protection) Act, 1972
(Inserted by Wildlife Protection Amendment Act, 2006)
They form the inviolate core of a Tiger Reserve.
2. Who declares a CTH?
•State Government notifies the CTH on recommendation of the National Tiger Conservation Authority (NTCA).
•NTCA bases its recommendation on scientific and objective criteria.
3. Purpose of a CTH
To provide a strictly protected, inviolate space for tiger breeding and conservation, where:
•Human activity is minimal to zero
•Core ecological processes remain intact
•Tiger reproduction and prey-base flourish
4. How are CTHs identified?
Identification requires:
Scientific Assessment
•Tiger population density
•Habitat quality
•Prey base
•Connectivity
•Ecological sensitivity
Consultation with Gram Sabhas
Mandatory consultation of affected forest-dwelling communities living inside proposed CTH.
5. Can people be relocated from CTHs?
Yes, but only if BOTH conditions are met:
1.Settlements cause irreversible damage to tiger habitat
2.Relocation is done ONLY with informed consent and due process, following Forest Rights Act, 2006
Relocation Process
•Must follow FRA Section 4(2) conditions
•Community forest rights are to be recognized first
•Two relocation options:
•₹15 lakh package per family (lump sum)
•Resettlement with full rehabilitation facilities
Forced eviction is illegal.

☑️What is “Doctrine of Clean Hands” ?
👉The Doctrine of Clean Hands is an equitable principle which states that:
A person who approaches the court must come with clean hands — i.e., without fraud, illegality, or bad faith. One who seeks equity must do equity.
In simple terms: If you act unfairly or dishonestly, you cannot demand fairness from the court.
👉Origin :
• Originates from English Equity Courts.
• Based on the maxim: “He who comes into equity must come with clean hands.”
👉Where is it applied in India?
Although not codified in any statute, Indian courts, especially High Courts and the Supreme Court, routinely apply this doctrine in:
• Writ jurisdiction (Articles 32 and 226)
• Equitable reliefs like injunctions, specific performance
• Public interest litigation (PILs) — to prevent misuse of PILs
👉Key Features
✔ 1. Applies only when relief sought is equitable
If the remedy is discretionary (like injunctions or writs), courts check if the party acted fairly.
✔ 2. Misrepresentation or suppression of facts = No relief
If a litigant hides material facts or lies, the court can dismiss the petition.
✔ 3. Prevents abuse of process
Ensures judicial process is not used for ulterior motives.
👉Important Supreme Court Cases
1. S.P. Chengalvaraya Naidu v. Jagannath (1994)
• Court held: A party who conceals material facts is not entitled to any relief.
• Famous quote: “A person whose case is based on falsehood has no right to approach the court.”
2. Dalip Singh v. State of U.P. (2010)
• SC observed rise in litigants with “unclean hands”.
• Courts must protect honest litigants.
3. K.D. Sharma v. SAIL (2008)
• Court dismissed a writ petition for suppression of material facts.
4. Tehseen Poonawalla v. Union of India (2018)
• Court emphasised purity of PIL jurisdiction.

✨Recently Microsoft CEO highlighted “Jevons Paradox” in the backdrop of increased adoption of the AI systems globally.
☑️What is “Jevons Paradox” ?
Jevons Paradox states that an increase in the efficiency of using a resource can lead to an overall increase in its consumption, not a decrease.
So,
Higher efficiency → lower cost of using resource → more demand → more total consumption
👉Origin
•Proposed by William Stanley Jevons, British economist, in 1865 in his book The Coal Question.
•Observation: More efficient steam engines increased total coal consumption in England, instead of reducing it.
👉Why does it happen?
1. Rebound Effect
Efficiency reduces cost → people use more of the resource.
2. Economic Expansion
Cheaper resource use boosts production → more industries → higher demand.
3. Behavioral Response
Users consume more because it’s cheaper or easier (e.g., fuel-efficient cars being driven more).
👉Examples (Indian & global)
✔ Fuel-efficient vehicles
Mileage improves → people drive more → total fuel consumption increases.
✔ Energy-efficient appliances
LEDs reduce cost of lighting → more lights used → higher electricity demand.
✔ Water-efficient irrigation (drip/sprinkler)
Lower water use per acre → farmers expand area under irrigation → total water use may rise.
✔ Coal power plants
Improved technology lowers cost → more coal-based generation → higher coal use.
