Study of the trace metal ion influence on the turnover of soil organic matter in cultivated contaminated soils [PDF]

open access: yes, 2006
The role of metals in the behaviour of soil organic matter (SOM) is not well documented. Therefore, we investigated the influence of metals (Pb, Zn, Cu and Cd) on the dynamic of SOM in contaminated soils where maize (C4 plant) replaced C3 cultures. Three

Tracking, feather moult and stable isotopes reveal foraging behaviour of a critically endangered seabird during the non‐breeding season

open access: yesDiversity and Distributions, Volume 23, Issue 2, Page 130-145, February 2017., 2017
Abstract Aim The movement patterns of marine top predators are likely to reflect responses to prey distributions, which themselves can be influenced by factors such as climate and fisheries. The critically endangered Balearic shearwater Puffinus mauretanicus has shown a recent northwards shift in non‐breeding distribution, tentatively linked to ...
