TL;DR: Studies of ecosystem processes on the Jornada Experimental Range in southern New Mexico suggest that longterm grazing of semiarid grasslands leads to an increase in the spatial and temporal heterogeneity of water, nitrogen, and other soil resources, which leads to the desertification of formerly productive land.

TL;DR: The DDP, supported by a growing and well-documented set of tools for policy and management action, helps navigate the inherent complexity of desertification and dryland development, identifying and synthesizing those factors important to research, management, and policy communities.

TL;DR: The scope of the thresholds concept in ecological science is defined and methods for identifying and investigating thresholds using a variety of examples from terrestrial and aquatic environments, at ecosystem, landscape and regional scales are discussed.

TL;DR: It was revealed that encroachment had mixed effects on ecosystem structure and functioning at global scales, and that shrub traits influence the functional outcome of encroachment.

TL;DR: Cotton plants were grown in CO2-controlled growth chambers in atmospheres of either 35 or 65 Pa CO2, and despite the accumulation of large amounts of starch, the photosynthetic characteristics of leaves in both treatments were similar, although the maximum rate of Rubisco activity (Vcmax) was ∼10% lower in leaves from plants grown in high CO2.
