STATE EYES FEMALE TIGERS FROM CENTRAL INDIA FOR STR
TOPIC: (GS3) ENVIRONMENT – SOURCE: TIMES OF INDIA
The Odisha government aims to tackle inbreeding and combat the prevalence of pseudo-melanistic tigers in the Similipal Tiger Reserve (STR) by introducing female tigers from other regions.
Inbreeding has led to genetic homogeneity and the proliferation of pseudo-melanistic tigers, posing challenges to the conservation of tiger populations.
Concerns and Request:
Pseudo-melanistic Tigers:
- The All-Odisha Tiger Estimation (AOTE 2023-24) report highlights the presence of 13 adult pseudo-melanistic tigers in STR, indicating inbreeding as a significant factor.
- Pseudo-melanistic tigers result from inbreeding and possess genetic traits leading to abnormal coat coloration.
Population Dynamics:
- STR harbors 24 adult tigers, holding the largest share of Odisha’s tiger population.
- All adult female tigers in the state reside in the reserve, making it crucial for conservation efforts.
Government Initiative:
- The Odisha government has written to the National Tiger Conservation Authority (NTCA), proposing the introduction of female tigers from other regions to augment genetic diversity.
- The initiative aims to address inbreeding and enhance the overall health and resilience of the tiger population in Similipal.
Inbreeding Challenges and Conservation Implications:
Genetic Homogeneity:
- Inbreeding results in reduced genetic diversity within a population due to closely related individuals reproducing.
- This leads to an increased prevalence of deleterious recessive traits and genetic uniformity.
Fitness and Health Concerns:
- Inbreeding depression reduces overall fitness, including reproductive success, survival rates, and overall health of individuals.
- Genetically similar individuals are more susceptible to diseases, posing risks to population viability.
Evolutionary Impacts:
- Limited genetic variation hampers a population’s ability to adapt to environmental changes or threats.
- Long-term inbreeding can lead to population decline, threatening species survival.
Conservation Strategies:
- Conservation efforts must prioritize maintaining or restoring genetic diversity to mitigate the adverse effects of inbreeding.
- Introducing genetically diverse individuals from other populations can rejuvenate gene pools and enhance population resilience.

FLUE CURED TOBACCO
TOPIC: (GS3) SCIENCE AND TECHNNOLOGY – SOURCE: THE HINDU
The Government of India has allowed the sale of Flue Cured Virginia (FCV) Tobacco on the Tobacco Boards auction platform.
Penalties on the sale of excess production by registered growers and unauthorized production by unregistered growers in Karnataka have been waived off.
About Flue Cured Tobacco:
Curing Process:
- Process to prepare harvested tobacco leaves for the market.
- Standardized method, especially in FCV tobacco, involves achieving desirable qualities and removing moisture.
Types of Curing:
- Air-Cured, Fire-Cured, and Flue-Cured are traditional methods.
- Each method results in distinct tobacco products based on nicotine content and aroma.
Why Tobacco is Cured:
- Essential for creating smoking tobacco.
- Wet, green tobacco leaves initially have too much moisture and chlorophyll.
- Curing removes excess moisture and releases chlorophyll, imparting flavor and scent to smoked tobacco.
Key Characteristics of FCV Tobacco:
- Production: Mainly used for cigarette tobacco.
- Content: High sugar, medium to high nicotine levels.
- Flavor and Aroma: Rich in natural tannins, providing a distinct mild and slightly sweet flavor.
- Production in India: FCV Tobacco is primarily produced in two states, Andhra Pradesh and Karnataka.
