Analysis of moose skulls documents a 16% shrinkage likely consistent with warming winters which are correlated with smaller brain size in one-year-old moose. The moose population has tripled in the past decade, reaching about 1,600 in the 2017 survey, but as wolf die off approaches, competition for food due to overpopulation will become a ...
In one study, wolves detected moose using scent ten times, vision six times, and once by following tracks in the snow. Their vision is as good as a human's, and they can smell prey at least 2.4 km (1 + 1 ⁄ 2 mi) away. One wolf traveled to a herd 103 km (64 mi) away. A human can detect the smell of a forest fire over the same distance from ...
A one-way trip on the National Park Service’s Ranger III ferry from Houghton, Michigan, to Isle Royale costs $80 for visitors over the age of 15 and $40 for visitors ages 1 through 15.
A chameleon successfully capturing prey with its tongue. In ecology, hunting success is the proportion of hunts initiated by a predatory organism that end in success. Hunting success is determined by a number of factors such as the features of the predator, timing, different age classes, conditions for hunting, experience, and physical capabilities.
Winter tick infestation is common with moose across the northern U.S. — usually survivable for adults but less so for calves, and miserable either way. Data collected over 19 years at Michigan ...

Persistence predators can hunt prey many times their size. No extant members of Archelosauria are known to be long-distance hunters, though various bird species may employ speedy pursuit predation. Living crocodilians and carnivorous turtles are specialized ambush predators and rarely if ever chase prey over great distances.
Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
