Inbreeding depression has been documented in many small, isolated wildlife populations.
When habitat fragmentation isolates Tapanuli orangutan subgroups, breeding options narrow. In small populations, individuals may become closely related over time. Inbreeding can reduce fertility and increase susceptibility to disease. With fewer than 800 individuals overall, maintaining genetic diversity is critical. Isolation accelerates loss of heterozygosity across generations. Genetic health depends on occasional dispersal between blocks. Without connectivity, inbreeding risk intensifies steadily. The species’ genetic resilience is tied directly to landscape continuity.
💥 Impact (click to read)
Inbreeding does not always produce immediate collapse, but it reduces long-term viability. Small populations accumulate genetic constraints that limit adaptability. In a rapidly changing environment, such rigidity is dangerous. Isolation compounds demographic fragility. Genetic erosion can outpace visible decline.
Protecting corridors prevents relatives from becoming the only breeding partners. Conservation planning must integrate genetic considerations alongside habitat protection. The Tapanuli orangutan’s future depends on keeping its gene pool dynamic. Isolation narrows possibility; connection sustains it.
