“…Plant species richness is regulated by complex interactions of related factors (Lamb, ). For example, it is not only closely related to productivity (Bai, Han, Wu, Chen, & Li, ; McCann, ; Williams, Seabloom, Slayback, Stoms, & Viers, ), but also to soil properties and ecosystem microclimate (Ives & Carpenter, ; Wang, Zhang, Zhu, Yang, & Li, ; Wu et al, ). As the main target of land use pattern, plant litter is also one of the main factors regulating plant community richness (Foster & Gross, ; Muller, Mesléard, Buisson, & Hölzel, ; Wardle, Bonner, & Nicholson, ).…”

Plant community diversity is conducive to maintain the regional ecosystems stability and ecosystem services. Seed germination is one of the main ways to regulate plant diversity, owing to seedling recruitment as a basis for plant community renewal. However, the exact mechanism of how plant litter affects seedling recruitment, and species richness is not yet fully understood. Therefore, a litter addition and removal experiment was established in a semiarid grassland to study the effects of plant litter on seedling recruitment and species richness from April to August in 2016 and 2017 in Northern China. The positive correlation between species richness and seedling recruitment indicated that a guarantee of seedling recruitment was the main precondition to protect species richness. Adding rather than removing litter significantly reduced species richness. Litter addition inhibited species richness by directly increasing mechanical damage or indirectly reducing photosynthetically active radiation and seedling recruitment. The results of this study are conducive to understand the evolutionary and regulatory mechanisms of community species richness and seedling recruitment in grassland ecosystems after adding or removing plant litter.

“…Additionally, vegetation patterns are associated with long-term competition for limited water and nutrient resources, which are affected by the spatial heterogeneity of surface-soil physicochemical properties (Wu et al, 2016). Distinct differences in BSC and BG patterns were found in the surface soil in this study (Figure 2).…”

In many arid ecosystems, vegetation frequently occurs in high-cover patches interspersed in a matrix of low plant cover. However, theoretical explanations for shrub patch pattern dynamics along climate gradients remain unclear on a large scale. This context aimed to assess the variance of the Reaumuria soongorica patch structure along the precipitation gradient and the factors that affect patch structure formation in the middle and lower Heihe River Basin (HRB). Field investigations on vegetation patterns and heterogeneity in soil properties were conducted during 2014 and 2015. The results showed that patch height, size and plant-to-patch distance were smaller in high precipitation habitats than in low precipitation sites. Climate, soil and vegetation explained 82.5% of the variance in patch structure. Spatially, R. soongorica shifted from a clumped to a random pattern on the landscape towards the MAP gradient, and heterogeneity in the surface soil properties (the ratio of biological soil crust (BSC) to bare gravels (BG)) determined the R. soongorica population distribution pattern in the middle and lower HRB. A conceptual model, which integrated water availability and plant facilitation and competition effects, was revealed that R. soongorica changed from a flexible water use strategy in high precipitation regions to a consistent water use strategy in low precipitation areas. Our study provides a comprehensive quantification of the variance in shrub patch structure along a precipitation gradient and may improve our understanding of vegetation pattern dynamics in the Gobi Desert under future climate change.

The complex structure of the abiotic factors in the Lesser Antilles leads to singular vegetation ranging from the dry to the humid. Geomorphology by means of the wide variety of topographic facets is the determining parameter which leads to gradients of mesological factors. Among the latter, both on the windward and leeward facades, the precipitation is distinguished by bioclimatic staging associated with plant stagings which consist of a mosaic of phytocenoses of variable sizes, ages, floristic compositions and structures as well as of different architecture. Based on examples of old and recent floristic surveys by authors which indicate ecotones, types and inversions of vegetation, we have shown the great phytocenotic diversity of the plant cover in the Lesser Antilles which are all biosystemic responses to the effects of natural and anthropogenic hazards. Thanks to this significant ecosystemic plasticity, the Lesser Antilles represent veritable laboratories for autoecological and synecological studies as well as of floristic succession.
