T1: A Survival Guide

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects.

The animal on the cover of T1: A Survival Guide is a caribou. Caribou, or reindeer, can be found in the arctic tundra, the mountain tundra, and the northern forests of North America, Russia, and Scandinavia. There are about 5 million caribou in the world, divided into three types: woodland, barren-ground, and Peary. A fourth type native to Canada, called the Queen Charlotte Island caribou, is extinct. One of the reasons the caribou is able to survive the northern climate is because its primary food source is lichen. The caribou’s keen sense of smell enables it to find lichen buried under the snow.

Caribou are the only members of the deer family in which both sexes grow antlers. Adult bulls shed their antlers around November or December after mating, while cows and young caribou often carry their antlers through the entire winter. During growth, the antlers have a fuzzy covering, or velvet, which contains blood vessels that carry nutrients.

In addition to their antlers, caribou have lateral hooves that allow their feet to spread on snow or soft ground. The hooves also act as paddles, making the caribou an excellent swimmer.
