Special Issue Information

Dear Colleagues,

We are pleased to announce a forthcoming Special Issue of Diversity focused on grassland ecosystems, which cover nearly 20% of the global terrestrial area and play an important role in species conservation, global carbon and water cycles as well as food supply.

In recent decades, grassland area experienced rapid climatic changes and sustained increases in human activities. As most of the grassland area covers vulnerable ecosystems, even minor disturbances can dramatically alter the structure and function of, or even completely destroy, the ecosystem, causing great diversity losses. How grassland diversity responds and adapts itself to these natural and artificial disturbances has recently drawn significant interest and become a global concern.

We hope anybody who is interested in this topic will contribute their research paper to this Special Issue. These valuable studies will provide us with insight into how grassland can be better managed and precisely protected for diversity conservation, thereby implementing visionary regulations on ecosystem functions and processes, which is key to maintaining sustainable global ecological security. Our effort may influence the future development of adaptive management practices for those endangered and damaged grassland ecosystems, thus making a contribution to diversity maintenance and species diversity.

Diversity will release a Special Issue on Response and Adaptation of Grassland Biodiversity to Natural and Human Disturbances. We invite papers from researchers sharing findings from field experiments, large-scale transect surveys, long-term observation, and remote sensing observations. All manuscripts are encouraged to provide raw data and code for enhanced reproducibility. This Research Topic will mainly address the following keywords, but other research refer to this topic will also be considered.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

As the woody legume, Prosopis glandulosa (honey mesquite) has encroached into grasslands and rangelands in the southern Great Plains, USA, two grass species, C4 shortgrass, Buchloe dactyloides (buffalograss), and C3 mid-grass, Nassella leucotricha (Texas wintergrass), have increased in dominance. Occurrence of more productive C4 mid-grasses and herbaceous diversity have declined. We measured effects of various combinations of spring clipping (to simulate cattle grazing) and summer and/or winter fire treatments on the stability of monoculture patches of these two grass species over an eight-year period, with the goal of reducing Nassella and increasing C4 mid-grass cover. All fire treatments top-killed most Prosopis trees that subsequently resprouted. Buchloe cover declined in the No Clip + No Fire treatment but remained intact with clipping and/or fire. Frequent clipping reduced Nassella cover across all fire treatments. Buchloe encroachment into Nassella patches was greatest in the Clip + Alternate Season fire treatment. C4 mid-grass cover increased to 15–25% in Nassella patches in several fire-only or Clip + Fire treatments; greatest gains were observed in treatments that included summer fire. In contrast, C4 mid-grass gains were lower in Buchloe patches. These results suggest that C4 mid-grass restoration was linked with treatments that reduced Nassella cover. Full article

Soil desertification is a serious problem in arid northwestern China that threatens ecological sustainability. Artemisia sphaerocephala, a dominant shrub species, play an important role in the conservation of water and the restoration of soil in the desert ecosystem. However, the poor establishment of A. sphaerocephala often limits plant revegetation, and the optimal population density for sustainable growth is largely unknown. Here, we determined key soil properties and plant growth characteristics associated with different population densities of A. sphaerocephala (including from 1.1, 2.1, 3.1, 3.9 to 5.3 plants per m2) in the resource-limited Alashan desert of northwestern China. The results showed that plant population density was the primary factor determining the revegetation of A. sphaerocephala, followed by soil water availability. Soil N, P and K content, and soil fractal dimensions also contributed to the vegetation and productivity. Soil nutrients were mostly accumulated in the topsoil layers, coincidental with the root distribution pattern in which 57% to 82% of total roots were distributed in the top 20 cm soil layer. The concentrations of soil nutrients in higher population densities (3.9 to 5.3 plants per m2) were greater than those in lower population densities (1.1 to 2.1 plants per m2), suggesting that A. sphaerocephala may have the ability to promote nutrient cycling in the desert ecosystem. We conclude that the optimal population density for the best growth of revegetated A. sphaerocephala was 3 plants per m2. Full article
