“…The reciprocity of vegetation and soil resource with succession time Many studies have found that there is strong reciprocity between vegetation and soil resources (reviewed by Burke et al 1998;Berendse 1998). The influence of soil resources on vegetation, especially those of N, P, and soil moisture and the consequences for successional dynamics has been examined (reviewed by Wedin and Tilman 1990;Adema and Grootjans 2003).…”

“…The interactions between plants and soils have received a great deal of attention (Burke et al 1998;Tracy and Sanderson 2000;Blatt et al 2002;Benjamin et al 2005). On one hand, the plant community may cause an accumulation of organic matter, and may change nutrient availability and moisture contents in the soil (DiTommaso and Aarssen 1989).…”

“…Between these limits (700-1,200 mm/year) are ecosystems in which the dominant effect on belowground or aboveground processes is unclear. Based on the research by Lauenroth et al (1997), Burke et al (1998) concluded that the key influence of soil on plant communities and composition in semiarid grasslands was through water availability, and that the important influence of the plants was on soil nutrient concentration. Thus, in arid and semiarid regions, the interactions of plant and soil processes are vital to the understanding of the mechanism of vegetation succession.…”

Aboveground and belowground changes during vegetation restoration and vegetation successions need to be characterized in relation to their individual responses to changes in soil resources. We examined above-and belowground vegetation characteristics, soil moisture, and nutrient status at the end of the growing season in 2006 in plots with vegetation succession ages of 2, 4, 6, and 8 years (two replicates each) that had been established on abandoned cropland, where potatoes had been grown for 3 years, using hoe and plow cultivation, immediately prior to vegetation clearance and subsequent natural plant colonization. A plant community comprising pioneer species [e.g., Artemisia capillaries, (subshrub)] was characterized by low levels of species richness (7.5±1.4 species m −2 ), plant density (35.7± 4.2 stems m −2 ), fine root length density (940.1± 90.1 m m −2 ), and root area density (2.3±0.3 m 2 m −2 ) that increased rapidly with time. Aboveground and belowground characteristics of both A. capillaries and the later successional species, Stipa bungeana (C3 perennial grass), increased in the first 6 years, but in the following 2 years A. capillaries declined while S. bungeana thrived. Thus, the fine root length density of A. capillaries, 812.4 m m −2 after 2 years, changed by a factor of 1.7, 2.0, and 0.4 in the 4th, 6th, and 8th years, whereas that of S. bungeana changed from 278.4 m m −2 , after 4 years, and by 1.7 and 23.3 times in the 6th and 8th years, respectively. Secondary vegetation succession resulted in reduced soil moisture contents. Soil available P and N mainly influenced aboveground characteristics, while soil moisture mainly influenced belowground characteristics. However, soil moisture had no significant affect on S. bungeana belowground characteristics at the population level in this semiarid region.

“…Shrubs usually occur on shallow, coarse and infertile soils (Groves, 1994), and are adapted to live on sandy soils with limited moisture. Shrubs often accumulate their organic matter beneath their canopies, thereby enriching the nutrient pool horizontally, enabling these species to grow in infertile soils (Zinke, 1962; Jackson & Caldwell, 1993; Schlesinger et al, 1996; Burke et al, 1998) and providing microclimatic conditions that stimulate microbial biomass and activity (Sandoval Pérez et al, 2016). …”

BackgroundShrubs play a key role in biogeochemical cycles, prevent soil and water erosion, provide forage for livestock, and are a source of food, wood and non-wood products. However, despite their ecological and societal importance, the influence of different environmental variables on shrub distributions remains unclear. We evaluated the influence of climate and soil characteristics, and whether including soil variables improved the performance of a species distribution model (SDM), Maxent.MethodsThis study assessed variation in predictions of environmental suitability for 29 Australian shrub species (representing dominant members of six shrubland classes) due to the use of alternative sets of predictor variables. Models were calibrated with (1) climate variables only, (2) climate and soil variables, and (3) soil variables only.ResultsThe predictive power of SDMs differed substantially across species, but generally models calibrated with both climate and soil data performed better than those calibrated only with climate variables. Models calibrated solely with soil variables were the least accurate. We found regional differences in potential shrub species richness across Australia due to the use of different sets of variables.ConclusionsOur study provides evidence that predicted patterns of species richness may be sensitive to the choice of predictor set when multiple, plausible alternatives exist, and demonstrates the importance of considering soil properties when modeling availability of habitat for plants.

“…Topography results in landscape scale heterogeneity in soil moisture and nutrient availability (Schimel et al 1991;Knapp et al 1993;Hook and Burke 2000) affects productivity and biodiversity (Knapp et al 1993;Fisk et al 1998;Fu et al 2004;Nippert et al 2011), and underlies the distribution of individual species (Barnes and Harrison 1982) and variation in plant functional traits (Choler 2005; Craine and Towne 2010) across the landscape. Topography may hold particular importance for the ecology of semi-arid steppe systems (Barnes and Harrison 1982;Milchunas et al 1989;Singh et al 1998;Hook and Burke 2000), where water plays a large role in limiting productivity (Burke et al 1998).…”

Legumes mitigate ecological consequences of a topographic gradient in a northern Mongolian steppe

et al. 2011

Topography should create spatial variation in water and nutrients and play an especially important role in the ecology of water-limited systems. We use stable isotopes to discern how plants respond both to ecological gradients associated with elevation and to neighboring legumes on a south-facing slope in the semi-arid, historically grazed steppe of northern Mongolia. Out of three target species, Potentilla acaulis, Potentilla sericea, and Festuca lenensis, when >30 cm from a legume, all showed a decrease in leaf δ(15)N with increasing elevation. This, together with measures of soil δ(15)N, suggests greater N processing at the moister, more productive, lower elevation, and more N fixation at the upper elevation, where cover of legumes and lichens and plant-available nitrate were greater. Total soil N was greater at the lower elevation, but not lichen biomass or root colonization by AMF. Leaf δ(13)C values for P. acaulis and F. lenensis are consistent with increasing water stress with elevation; δ(13)C values indicated the greatest intrinsic water use efficiency for P. sericea, which is more abundant at the upper elevation. Nearby legumes (<10 cm) moderate the effect of elevation on leaf δ(15)N, confirming legumes' meaningful input of N, and affect leaf δ(13)C for two species, suggesting an influence on the efficiency of carbon fixation. Variation in leaf %N and %C as a function of elevation and proximity to a legume differs among species. Apparently, most N input is at upper elevations, pointing to the possible importance of grazers, in addition to hydrological processes, as transporters of N throughout this landscape.
