The impact on nitrogen (N) and phosphorus (P) cycles of human activity is a growing
concern and has several causes and consequences (MacDonald et al., 2011; Peñuelas et …

Abstract Background In the Mediterranean climate, plants have evolved under conditions of
low soil-water and nutrient availabilities and have acquired a series of adaptive traits that, in …

基于对黑河流域中下游荒漠区植被和土壤生境的调查分析, 以土壤水分在各调查样地中的差异来
反映研究区的生态水文特征, 采用种的丰富度和多度来代表荒漠植物多样性研究了荒漠植物 …

Dryland ecosystems account for ca. 27% of global soil organic carbon (C) reserves, yet it is
largely unknown how climate change will impact C cycling and storage in these areas. In …

The adaptation of plants to particular soil types has long intrigued biologists. Gypsum soils
occupy large areas in many regions of the world and host a striking biological diversity, but …

Impacts of soil tillage and cover crops on soil carbon (C) dynamics and microbiological
function were investigated in a vineyard grown in California's mediterranean climate. We (1) …

Biological soil crusts (BSCs), composed of lichens, cyanobacteria, mosses, liverworts and
microorganisms, are key biotic components of arid and semi-arid ecosystems worldwide …

Climate change scenarios predict increases in temperature, changes in precipitation
patterns, and longer drought periods in most semi-arid regions of the world. Ecosystems in …

Heterotrophic soil microbial respiration—one of the main processes of carbon loss from the
soil to the atmosphere—is sensitive to temperature in the short term. However, how this …

A long-term field experiment was conducted to examine the influence of mineral fertilizer
and organic manure on the equilibrium dynamics of soil organic C in an intensively …
