The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Hydrological Factors for Phosphorus Transfer from Agricultural Soils

, 1999
Understanding and managing against phosphorus (P) transfer from agricultural soils to receiving waters is a multidisciplinary task in which the role of hydrology is particularly difficult to simplify. We review current knowledge to define the spatial and temporal controls on P transfer from agricultural soils via the various hydrological pathways ...

Developing a macroecology for human‐altered ecosystems

Ecography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

A new and integrated hydro-economic accounting and analytical framework for water resources: A case study for North China [PDF]

, 2008
Water is a critical issue in China for a variety of reasons. China is poor of water resources with 2300 m3 of per capita availability, which is less than of the world average. This is exacerbated by regional differences; e.g.

Assessing the Sustainability of Community‐Managed Irrigation Systems Using Multicriteria Analysis and Sustainability Indicators in Northern Ethiopia: A Holistic Approach

Irrigation and Drainage, EarlyView.
ABSTRACT Reservoir‐based irrigation schemes (RBISs) have been developed to minimize the adverse effects of moisture stress and improve the livelihoods of smallholder farmers in semi‐arid regions. However, many RBISs perform below expectations. A multistage expert elicitation approach and an indicator‐based Sustainability Assessment of Food and ...
