Male giraffes fight each other by 'necking'! They push their long necks against each other, bending and twisting them in order to win the fight by a show of strength. Many animals fight this way, including snakes, insects and crabs. Competing in this way allows animals to find out who's boss while protecting themselves from injury. The strongest wins and the loser just has to go away.
Subalpine Ecosystems
Subalpine forests are found at the edge of treeline, either towards the tops of mountains or close to the arctic. The treeline may be sudden or it may be gradual. Subalpine ecosystems in the temperate regions have distinct seasons when they grow, and spend time covered in snow. These ecosystems grow slower and less is known about them than those in the valley bottoms. It's a big challenge to conservation biologists to learn how to protect the subalpine forests by managing sustainable development.
