                 Tracking tigers through the cold Russian winter



                        CFC professor’s research is helping to preserve

                                   one of the world’s top predators

                                              by Jason D.B. Kauffman



Working with large carnivores has given Mark Hebblewhite many exciting stories about

wild landscapes and the wild animals that live there. Close to home, the Assistant Professor of

Ungulate Habitat Ecology at UM’s College of Forestry and Conservation, in the Wildlife Biology

Program, has researched top predators like mountain lions and gray wolves.



And while that work has been highly rewarding for this native of Canada, it’s been his more

recent research efforts with a ghost-like denizen of the forests of the Russian Far East that

have really become the highlight of his career. There, north of Korea and sandwiched between

northern Japan and China right on the Sea of Japan, what is arguably the planet’s greatest

remaining predator stalks its prey where the northern boreal taiga mixes with southern

deciduous oak forests.



Here in this rich habitat the world’s remaining 400 Siberian tigers cling to existence. The

subspecies, which is more accurately called the Amur tiger after the Amur River basin, is the


largest of all the world’s largest cats. The Amur River, the tenth longest river system in the

world, drains this tiger stronghold.

Last January, Hebblewhite got to do something few wildlife biologists have been fortunate enough to experience:   track a large, radio-collared adult male tiger through its habitat in the Russian Far East. Now nearly a half-year later, he still gushes about the experience.  Hebblewhite’s Russian counterparts have  nicknamed the massive 220-kilogram  (nearly 500 pounds) tiger “Sheriff.”

why?气候变暖不是应该体型变小么~
或者生境破碎化状况好转,male tiger的领域扩大了~

不大,圈养的健康西虎长到250到300是很正常的,个别大个子长到350都不显胖。
气候越温暖,生物体积越庞大,地球上的大家伙不管动物还是植物几乎都在热带地区

那是因为温带的大型动物被人类杀完了。猛犸、巨犀都比非洲象大,洞狮、拟狮也比非洲狮大。只是人类进入新石器时代以后,它们全都灰灰了。

亚马逊的鱼比长江黄河的大多了,非洲鳄也远大于扬子鳄[:a10:]

冷血的当然是越冷个子越难长大。
不过你的例子也不对,长江里的白鲟是世界淡水鱼类中最长的。亚马逊的大鱼比长江多只不过是其规模大,大个体比其他地方容易发现;生态压力小,大个体更容易长成,给人造成的错觉。非洲的鳄也不都是尼罗鳄。中国虽然只有扬子鳄,但纬度接近且血源也接近的密西西比鳄并不小。反过来,最小的那些鳄鱼,全都长在热带呢。
