    Description / Table of Contents: The Carbiocial Project investigates viable carbon-optimized land management strategies for maintaining tropical ecosystem services under land use change and changing climate conditions in Southern Amazonia – a hotspot of global change. The project aims at understanding the vital natural processes and socio-economic driving forces in the region and develops strategies to enhance and protect carbon stocks in the recently deforested agroscapes of Central/Northern Mato Grosso and South Pará. That is why Carbiocial analyzes and models soil, water and climate as well as agro-economics, social and political transformations. Based on detailed storylines, the project aims at identifying possible entry-points for a necessary change in local and regional production patterns, considering local livelihoods as well as the present national and global economic, legal and political situation. This book gives an overview of the first results of the multi-disciplinary Carbiocial Project by publishing the main presentations, held on the Carbiocial Status Conference, on October 7-8, 2013, in Cuiabá. In sixteen chapters the authors elucidate the project‘s current state of knowledge, illustrating adapted methods for regional modeling and promising strategies for the Amazon development. | Contents --- Stefan Hohnwald & Gerhard Gerold: Carbon-Optimized Land Management Research for the Southern Amazon-Geographical and Organizational Settings of the Carbiocial-Carbioma Project Consortium --- Philip M.

    Description: Terrestrial herbs are important elements of tropical forests; however, there is a lack of research on their diversity patterns and how they respond to different intensities of forest-use. The aim of this study was to analyze the diversity of herbaceous angiosperms along gradients of elevation (50 m to 3500 m) and forest-use intensity on the eastern slopes of the Cofre de Perote, Veracruz, Mexico. We recorded the occurrence of all herbaceous angiosperm species within 120 plots of 20 m x 20 m each. The plots were located at eight study locations separated by ~500 m in elevation and within three different habitats that differ in forest-use intensity: old-growth, degraded, and secondary forest. We analyzed species richness and floristic composition of herb communities among different elevations and habitats. Of the 264 plant species recorded, 31 are endemic to Mexico. Both α- and γ-diversity display a hump-shaped relation to elevation peaking at 2500 m and 3000 m, respectively. The relative contribution of between-habitat β-diversity to γ-diversity also showed a unimodal hump whereas within-habitat β-diversity declined with elevation. Forest-use intensity did not affect α-diversity, but β-diversity was high between old-growth and secondary forests. Overall, γ-diversity peaked at 2500 m (72 species), driven mainly by high within- and among-habitat β-diversity. We infer that this belt is highly sensitive to anthropogenic disturbance and forest-use intensification. At 3100 m, high γ-diversity (50 species) was driven by high α- and within-habitat β-diversity. There, losing a specific forest area might be compensated if similar assemblages occur in nearby areas. The high β-diversity and endemism suggest that mixes of different habitats are needed to sustain high γ-richness of terrestrial herbs along this elevational gradient.
