Grassland Research, EarlyView.Abstract Background Plant allometry theory developed in the last century focused on 2/3‐power scaling, determined by light interception considerations. More recently, 3/4‐power scaling based on the properties of vascular distribution networks has been proposed.

The Journal of Wildlife Management, EarlyView.The North Slave Métis Alliance's Indigenous Guardianship Program conducted on‐the‐ground patrols monitoring caribou interactions with the Tibbitt to Contwoyto Winter road and quantify caribou harvest. Quantifying the impacts of winter roads on barren‐ground caribou herds supports community members’ commitment to safeguarding their traditional territory

The Journal of Wildlife Management, EarlyView.Snowshoe hare population densities in Pennsylvania were greatest in early‐successional forest and densely‐understoried mature forest. Forest management that increases and maintains the amount of early‐successional forest, or that increases understory complexity in mature forest, would benefit snowshoe hares and may mitigate population declines under ...

Birds among us: Perceptions of bird‐mediated services and disservices in a northern city
People and Nature, EarlyView.Abstract Birds can benefit people or cause harm. Understanding how people perceive birds in cities, where most daily interactions among people and nature occur, could inform decision‐making in support of biodiversity and human well‐being We distributed a survey in a growing mid‐sized city (Lahti, Finland) to evaluate which bird‐mediated ecosystem ...
