摘要

加拿大猞猁是什么?加拿大猞猁是一种神秘的,生活在北纬和高山的森林里的猫科动物。加拿大猞猁是一种中等大小的猫,类似于山猫。它有更长的腿和毛茸茸的大爪子,在深冬雪中机动的适应性令人印象深刻。它的耳朵上也有长长的绒毛和一条短而黑的尾巴。猞猁的活动范围是什么?加拿大猞猁的历史和现在的北美范围包括阿拉斯加,加拿大和许多其他北部48个州。因此,很难确定居住猞猁种群的历史或当前位置。猞猁的活动范围包括以下14个州:加拿大猞猁吃什么?猞猁是高度专业化的捕食它们的主要猎物,雪蹄兔(美洲兔)。猞猁的长腿和大脚就像雪鞋一样,所以它们可以有效地追踪和捕捉野兔。事实上,在大多数地方,猞猁与雪鞋兔的关系如此紧密,以至于猞猁的数量随着雪鞋兔的数量而周期性地上升和下降。猞猁也吃老鼠、田鼠和鸟类。猞猁需要什么样的栖息地?更老的、成熟的森林里有倒下的树木和风吹来的东西,为洞穴提供了掩护,也为躲避恶劣天气提供了保护。猞猁主要以雪兔为食,雪兔生活在茂密的小树和灌木丛中。在五大湖地区和美国东北部,猞猁的栖息地是常绿和硬木混合的森林,如枫树和桦树。在落基山脉和喀斯喀特山脉,猞猁生活在高山的云杉/冷杉林中。是什么威胁着山猫?加拿大猞猁在美国本土48个州的数量可能从未像在加拿大北部和阿拉斯加那么多,因为猞猁和雪鞋兔在山脉南部的栖息地较少。猞猁主要生活在联邦土地上,尤其是在西部。管理局的结论是,美国本土猞猁面临的威胁是目前联邦土地管理计划中缺乏保护该物种的指导。该机构正在与其他联邦机构合作,保护猞猁的栖息地。人们正在采取什么措施来保护猞猁?因为森林在不断变化,如果不仔细规划,今天的猞猁栖息地可能不会是未来的猞猁栖息地。重要的是,目前的森林管理……

Canada Lynx
What is a Canada lynx? The Canada lynx is a secretive, forest-dwelling cat of northern latitudes and high mountains. The Canada lynx is a medium-sized cat, similar to the bobcat. It has longer legs and very large well-furred paws, impressive adaptations for maneuvering through deep winter snow. It also has long tufts on the ears and a short, black-tipped tail. What is the range of the lynx? The historical and present North American range of the Canada lynx includes Alaska, Canada, and many of the other northern 48 States. Therefore, it is difficult to determine either the historic or current location of resident lynx populations. The range of the lynx includes the following 14 States: What do Canada lynx eat? Lynx are highly specialized to hunt their primary prey, the snowshoe hare (Lepus americanus). The lynx's long legs and large feet act like snowshoes so they can effectively track and catch hares. In fact, in most places, lynx are so tied to snowshoe hares that lynx populations rise and fall in cycle with snowshoe hare numbers. Lynx also will eat mice, voles, and birds. What kind of habitat do lynx require? Older, mature forests with downed trees and windfalls provide cover for denning sites, escape, and protection from severe weather. Lynx feed primarily on snowshoe hare, which live in dense thickets of younger trees and shrubs. In the Great Lakes area and the northeastern United States, lynx habitat is forest that is a mix of evergreens and hardwoods, such as maple and birch. In the Rocky Mountains and Cascade Mountains, lynx live in the spruce/fir forests of the high mountains. What is threatening the lynx? Canada lynx likely have never been as abundant in the lower 48 States as they were in northern Canada and Alaska because there is less lynx and snowshoe hare habitat at the southern part of the range.
