Background

Overview

Understanding the biological principles behind conservation efforts is vital. Genetic diversity is a core concept in ecology and conservation biology, directly impacting the success or failure of species protection and management strategies.

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species. It is crucial for the long-term survival and adaptability of populations, allowing them to cope with environmental changes, diseases, and other stressors. Low genetic diversity, often due to inbreeding in small, isolated populations, can lead to reduced fitness and increased vulnerability to extinction.

Key facts

Importance

Essential for species' resilience and adaptation to changing environments and diseases.

Threats

Small, isolated populations are prone to low genetic variation and inbreeding depression.

Consequences

Leads to reduced fertility, survival rates, increased susceptibility to diseases, and genetic load.

Indicator

Pseudo-melanism in Similipal tigers is linked to genetic isolation and reduced diversity.
