Opposing fitness consequences of habitat use in a harvested moose population
Abstract Landscape changes are happening at an unprecedented pace, and together with high levels of wildlife harvesting humans have a large effect on wildlife populations.

Abstract Landscape changes are happening at an unprecedented pace, and together with high levels of wildlife harvesting humans have a large effect on wildlife populations. A thorough knowledge of their combined influence on individual fitness is important to understand factors affecting population dynamics.

Using data from a closely monitored and harvested population of moose Alces alces , we examined how individual variation in offspring size, reproduction and survival was related to the use of open grasslands; a habitat type that offers high‐quality forage during summer, but at the cost of being more exposed to hunters in autumn. The use of this habitat type may therefore involve a trade‐off between high mortality risk and forage maximization.
