Extinction Filtering

Extinction Filtering Latest News 

Recent study finds that human activities outside protected areas are driving biodiversity loss and extinction filtering is affecting sensitive species.

About Extinction Filtering

• It is the process where species sensitive to human disturbance disappear, leaving only those that can survive in degraded landscapes.
• It predicts that species that have evolved and survived in high-disturbance environments should be more likely to persist in the face of new disturbances, including those of habitat loss and fragmentation 
• The existence of anthropogenic extinction filtering acting on mammals in tropical forests, whereby human overpopulation has driven the most sensitive species to local extinction while remaining ones are able to persist, or even thrive, in highly populated landscapes and mainly depend on habitat cover

Impact of Extinction Filtering on Biodiversity

• It results in a less diverse and more uniform mix of species in tropical forests.
• Over time, this weakens entire ecosystems and reduces their ability to recover from environmental changes.

Extinction Filtering FAQs

Q1: What is in a tropical forest?

Ans: The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers.

Q2: What is the definition of a mammal?

Ans: These are any members of the group of vertebrate animals in which the young are nourished with milk from special mammary glands of the mother.
