Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Physical trampling is a ubiquitous activity of walking vertebrates, but is poorly understood as a mechanism impacting biogeochemical cycling in soil. Lack of detailed knowledge of soil abiotic–biotic interactions underlying trampling effects, and the primary sources of ...

Temporal community change in stream ecosystems varies by assemblage across US climates
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

A Real Option Approach to the Protection of a Habitat Dependent Endangered Species [PDF]
We use a real option approach to determine optimally when a social planner has to stop or resume logging in situations where an endangered species relies on forest habitat for its survival, and that habitat evolves stochastically.

Lichen bleaching as a response to long‐term experimental warming in the High Arctic
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape
Animal Conservation, EarlyView.Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.
