Heating effects on carbon and mineral nitrogen contents of soils within different land use types were investigated in this study. With this intention we collected soil samples from 3 different land use types which are abandoned agricultural lands (AAL), shrub land (SL) and Oak forest land (OFL) and are in neighborhood with each other. The sampling was made at mid-summer to provide a better corr...
n 1955, the African National Congress (ANC) held its historic Congress of the People to ratify its liberation manifesto, the Freedom Charter. This event took place in Kliptown, on the outskirts of Soweto (fig. 1, above), at a site that came to be called Freedom Square in honor of the occasion. Today Freedom Square is an open, windswept tract of land, lying between a shack settlement, a railway ...
The effects of increasing carbon dioxide (CO2) and climate on net carbon storage in terrestrial ecosystems of the conterminous United States for the period 1895-1993 were modeled with new, detailed historical climate information. For the period 1980-1993, results from an ensemble of three models agree within 25%, simulating a land carbon sink from CO2 and climate effects of 0.08 gigaton of carb...
High landscape diversity is assumed to increase the number and level of ecosystem services. However, the interactions between ecosystem service provision, disturbance and landscape composition are poorly understood. Here we present a novel approach to include uncertainty in the optimization of land allocation for improving the provision of multiple ecosystem services. We refer to the rehabilita...
Leptospirosis is a disease that disproportionately affects impoverished urban communities, but likely to become more prevalent as changing climate alters flooding regimes. The persistence and transmission of the Leptospira pathogen reliant on small vertebrate animals, predominantly rodents. In this issue Molecular Ecology, Peterson et al. demonstrate how changes in rodent diversity abundances a...
