ANTHROPOGENIC CAUSES OF EXTINCTION Flashcards
WHAT IS HABITAT DESTRUCTION?
process by which a natural habitat becomes incapable of supporting its native species ; it is one of the primary causes of biodiversity loss in the Philippines
WHAT IS HABITAT FRAGMENTATION?
occurs when humans break larger habitats into smaller isolated scattered places ; 50% of the world’s tropical rainforests have been converted for other purposes
WHAT IS AN INVASIVE SPECIES?
an organism that is indigenous or native to particular area deliberately or (may not a be accidentally introduced); competition may ensue between the native and non-native species ; may cause extinctions of native plants and animals:reducing biodiversity ; may impair ecosystems

WHAT IS OVEREXPLOITATION?
occurs when harvesting exceeds reproduction of wild plant and animal species; continues to be a major threat to biodiversity ; Forest loss in the Philippines has left only 12% of historical primary forest cover remaining (Verburg & Veldkamp 2004)
