Global soil organic carbon (SOC) stocks may decline with a warmer climate. However, model projections of changes in SOC due to climate warming depend on microbially-driven processes that are usually parameterized based on laboratory incubations. To assess how lab-scale incubation datasets inform model projections over decades, we optimized five microbially-relevant parameters in the Microbial-ENzyme Decomposition (MEND) model using 16 short-term glucose (6-day), 16 short-term cellulose (30-day) and 16 long-term cellulose (729-day) incubation datasets with soils from forests and grasslands across contrasting soil types. Our analysis identified consistently higher parameter estimates given the short-term versus long-term datasets. Implementing the short-term and …

The aim of this study is to assess the composition of mammalian and avian communities in sites under two different cattle management plans: one where sheep are present along bovine cattle and another where pastures are grazed solely by bovines.

With Morocco’s geographical situation (at the crossroads between Europe and Africa, the Mediterranean Sea and the Atlantic Ocean), its diverse climate and habitats supports a varied natural vegetation. The floristic richness of the country is related to the heterogeneity of biotypes. From the desert to the high mountains and the littoral to the continental borders, Morocco offers varied ecological conditions that support many different plant species. Steppes and grasslands are important parts of the main plant associations encountered in Morocco. They contain a wealth of flora, play important ecological roles and, from a socioeconomic perspective, are highly significant.
