Impacts of Pleistocene extinctions on the biomass and energy use of local mammal assemblages around the world

Ecography, EarlyView.
Many of the world's megafaunal species went extinct during the late Quaternary, leading to dramatic reductions in community and ecosystem functioning. While the nature and severity of the extinctions are well documented on global and continental scales, less is known about local‐scale impacts.

Dakota skipper distribution model for North Dakota, South Dakota, and Minnesota aids conservation planning under changing climate scenarios

Frontiers in Ecology and Evolution
Species distribution models are useful conservation planning tools for at-risk species, especially if they are linked to planning efforts, conservation delivery, and a changing environment. The Dakota skipper (Hesperia dacotae) is an endemic butterfly of

Climate and microbial community composition drive shifts in ecosystem function along three parallel elevational gradients

Ecography, EarlyView.
Mountains are home to steep elevational gradients in environmental factors, biodiversity and ecosystem functionality. Though these gradients are tightly connected, little is known about the relative contribution of environmental and biotic factors in driving elevational changes in ecosystem functionality.

The Role of European Union (EU) Metagovernance in Supporting the Voluntary and Community Sector in Northern Ireland

European Policy Analysis, EarlyView.
ABSTRACT This article argues that European Union (EU) peacebuilding scholarship can benefit from organizational research on the socio‐spatial dynamics of policy implementation. It introduces a strategic‐relational heuristic to address two key gaps: the marginalization of grassroots agency in spatial analyses and the separation of strategy from ...
