Habitat-specific demography and source-sink dynamics in a population of Siberian jays

, 2010
P>1. There are a number of models describing population structure, many of which have the capacity to incorporate spatial habitat effects. One such model is the source-sink model, that describes a system where some habitats have a natality that is higher

A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

Wildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Root and leaf litter diversity below‐ground shape soil carbon stabilization and priming through altered decomposition dynamics

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root and leaf turnover is a major contributor to soil organic carbon (SOC) dynamics and storage. However, while roots of multiple species occur in soils, and leaves are often incorporated to soil by bioturbation processes, it remains unknown how litter mixing in soils ...

Decreasing water availability reduces productivity in Swiss forests along an altitudinal gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests are one of the most important terrestrial carbon sinks, but are increasingly under pressure due to drought, heat and the occurrence of extreme events. There are opposing longer term trends for European forest growth reported, and severe drought and disturbance ...

Towards stochastic simulation of crop yield: a case study of fruit set in sweet pepper

, 2010
Crop growth simulation models are widely used in research and education, and their use in commercial practice is increasing. Usually these models are deterministic: one set of input values always gives the same output of the model.

Source - sink balance and manipulating sink - source relations of wheat indicate that the yield potential of wheat is sink-limited in high-rainfall zones

, 2010
Grain yield depends on the number of grains per unit area (sink) and the availability of assimilates (source) to fill these grains. The aim of the current work was to determine whether wheat yield in the high-rainfall zone of south-western Australia is ...

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures

British Journal of Management, EarlyView.
Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

The Canary Down the Coalmine: Dagenham, London and Labour Politics

The Political Quarterly, EarlyView.
Abstract The history of Dagenham offers unique insights into both the changing composition of the working class and the forces that have reshaped domestic politics throughout the last 100 years, particularly the politics of the British labour movement.
