What is Ecological Niche ? • Ecological Niche is the role that each species plays in its environment ( affecting its survival as a species )
Parameters of a Niche. • An organisms life history. • Habitat. • Place in the food chain. • Geographic Range.
ECOLOGICAL NICHE: EXTINCTION OF DINOSAURS ! The mass extinction of dinosaurs may have led the way for mammals to expand into the dinosaurs niches.
White Pine Tree at Yellow Stone and its Not so Friendly Guest. • The White Pine is a host to the Mountain Pine Beetle. • The mountain pine beetle, belongs to the bark beetle family, that must kill their host to reproduce. • The Pine beetle invades the bark of the tree so that the tree dies from inside out.
The Effects of Global Warming. • Climate and weather play a role in the number of mountain pine beetles. • The seasonal weather of the high mountains protected the White Bark Pine from beetles.
GLOBAL WARMING Continued … • Due to global warming, the winter temperatures have increased allowing the beetle to survive. • After the beetle has invaded , the tree turns red.
White Bark Pine Ecosystem. • White Bark Pine is a tree that plays a big role in the ecosystem. • It provides seeds which are a major food source for animals. • The mass destruction of these white pines will affect the animals that depend on them for survival. • This effects the ecological niche of many animals.

DID YOU KNOW ? • Not more than ONE species can occupy the same niche. • Every year the pine tree invasion increases due to global warming. • When a beetle invades a tree, it leaves it red. Scientists use this as an ecological indicator to show the rapid change every year.
