Snowshoe Hare Camouflage
How snowshoe hares evolved to stay seasonally camouflaged Date: June 21, 2018 Source: The University of Montana Summary: Many animals have evolved fur or feather colors to blend in with the. Snowshoe Hares, Seasonal Camouflage, and the Consequences of Transitioning Too Early by Rachael Cheff Broadcast 12.2021 & 12.13 & 12.16.2023. Abstract Snowshoe hares (Lepus americanus) maintain seasonal camouflage by molting to a white winter coat, but some hares remain brown during the winter in regions with low snow cover.
We show that cis. Description Snowshoe hares have an interesting adaptation that helps protect them against predators. Depending on the season, their fur can be a different color.

During the winter, snowshoe hares are white, which helps them blend in with the snow. When the seasons change to spring and summer, snowshoe hares turn a reddish. As New England warms, snowshoe hares are increasingly finding themselves the wrong color for camouflaging with their environment.
New England scientists are looking at some promising ways to help. Snowshoe hares change fur color for camouflage. In winter, their fur turns white to match the snow, which helps them hide from predators.

In spring and summer, it changes to reddish-brown, allowing them to blend in with dirt and rocks. This seasonal adaptation improves their survival in different environments. Environmental factors influence this fur color change.
The varying lengths of. Snowshoe hares might be able to minimize fitness costs of seasonal mismatch in camouflage through plasticity in the phenology of coat colour moults. Timing of moult in autumn and spring is presumably initiated by photoperiod, but temperature and possibly presence of snow may affect the rate of the change [15 - 17].

Survival Through Camouflage The primary reason for the snowshoe hare's seasonal color change is camouflage, which aids their survival. Matching their fur color to the environment makes hares less visible to predators. In summer, their brown coats allow them to disappear against the forest floor and undergrowth.
Snowshoe hares (Lepus americanus) typically molt into white winter coats to remain camouflaged against snow. In some warmer climates, hares have evolved brown winter camouflage. In snowshoe hares, breeding with with black-tailed jackrabbits provided critical coat color variation that was needed to adapt in regions where winter snow is low or nonexistent.
"Brown winter coats are currently rare across the range of snowshoe hares," said Professor Good.
