This study sets out to verify the key predictors of the dynamics of the arable production per capita index, the arable production and permanent crop land and forest area at a national scale in Cameroon. To achieve this objective, data for twelve time series data variables spanning the period 1961-2000 were collected from Oxford University, the United Nations Development program, the World Bank,...

Th e arable weeds (segetal fl ora) were explored on Plešivica hills (NW Croatia) during vegetational seasons 2002 and 2003 at 10 locations. Th e common methods of plant recording, collecting and identifi cation were applied in the research of the arable weeds. Th e nomenclature of plants was according to Tutin et al. (1964-1980, 1993). Th e total of 107 taxa of arable weeds that classifi ed to ...

Protected areas are a relevant conservation tool at our disposal, especially for developing management strategies of natural habitats. However, explicit tests large spatial scales about its effectivity protecting different components biodiversity still rare. This study explored the matching between distribution three avian diversity (taxonomic, functional, and phylogenetic metrics) network Natu...

Editorial Some authorities interpret measured increases in global temperatures as indicating an approaching major change in climate around the world although there is argument about both the extent and the origin of the phenomenon as well as its climatic implications. While in some quarters the carbon dioxide generated by human activities is regarded as the major driver of global temperature in...

Soil structure in natural systems is a product of complex interactions between biological activity, climate and soil minerals that promote aggregation accumulation biopores. In arable lands, the management often requires mechanical fragmentation hardened to improve seedbed, control weeds bury plant residue. Despite difficulties defining quantifying structure, its critical role evidenced by loss...

Artificial vegetation restoration can induce variations in accumulation and distribution of soil carbon (C), nitrogen (N) and phosphorus (P). However, little is known about variations in soil C, N and P nutrient fraction stratification following artificial vegetation in Loess Plateau China. Based on the hypothesis that re-vegetated can improve soil quality and stratification ratios (SR) can be ...

The impact of ancient fertilization practices on the biogeochemistry of arable soils on the remote Scottish island of Hirta, St Kilda was investigated. The island was relatively unusual in that the inhabitants exploited seabird colonies for food, enabling high population densities to be sustained on a limited, and naturally poor, soil resource. A few other Scottish islands, the Faeroes and some...
