“…The authors discuss the implications of these findings, the importance of teasing apart physical and chemical controls over plant germination, and the dynamics of invasion by B. tectorum in a warmer world. Muñoz-Rojas et al (2018) show that bio-priming of shrub seeds with Microcoleus and Nostoc spp. has the potential to enhance soil functionality in mine-waste soil by increasing the survival of Australian native plants that fix substantial amounts of nitrogen.…”

“…The cultivation of this type of photosynthetic microorganisms in agro-industrial wastewater is presented as an exciting alternative to develop as tertiary wastewater treatments, avoiding the environmental impact that arises with the discharge of this type of sewage into bodies of water. Additionally, due to the elemental composition (C:N:P), presented by the biomass of A. platensis, it can be used as a biofertilizer or a biostimulant in agriculture [65][66][67].…”

The unique perspective that microalgae biomass presents for bioenergy production is currently being strongly considered. This type of biomass production involves large amounts of nutrients, due to nitrogen and phosphorous fertilizers, which impose production limitations. A viable alternative to fertilizers is wastewater, rich in essential nutrients (carbon, nitrogen, phosphorus, potassium). Therefore, Arthrospira platensis was cultivated in 150 mL photobioreactors with 70% (v/v) with the wastewater from a dairy industry, under a regime of light:dark cycles (12 h:12 h), with an irradiance of 140 μmol m−2 s−1 photon. The discontinuous cultures were inoculated with an average concentration of chlorophyll-a of 13.19 ± 0.19 mg L−1. High biomass productivity was achieved in the cultures with wastewater from the dairy industry (1.1 ± 0.02 g L−1 d−1). This biomass was subjected to thermal and physical treatments, to be used in co-digestion with cattle manure. Co-digestion was carried out in a mesophilic regime (35 °C) with a C: N ratio of 19:1, reaching a high methane yield of 482.54 ± 8.27 mL of CH4 g−1 volatile solids (VS), compared with control (cattle manure). The results demonstrate the effectiveness of the use of cyanobacterial biomass grown in wastewater to obtain bioenergy.

“…In recent years, studies have highlighted the key role of BSC as ‘ecological engineers’ in drylands, by enhancing soil function and structure (Antoninka et al ; Park et al ). Some studies have revealed the effects of BSC on seed germination and seedling growth of vascular plants through laboratory and greenhouse experiments (Zhang & Belnap ; Muñoz‐Rojas et al ). However, the mechanism underlying the effects of BSC succession on community dynamics is not clear.…”

The effects of biological soil crusts (BSC) on vascular plant growth can be positive, neutral or negative, and little information is available on the impacts of different BSC successional stages on vascular plant population dynamics.• We analysed seedling emergence, survival, plant growth and reproduction in response to different BSC successional stages (i.e. habitats: bare soil, cyanobacteria, lichen and moss crusts) in natural populations of Echinops gmelinii Turcz. in the Tengger Desert of northwest China. The winter annual E. gmelinii is a dominant pioneer herb after sand stabilisation.• During the early stages of BSC succession, the studied populations of E. gmelinii were characterised by high density, plant growth and fecundity. As the BSC succession proceeded beyond moss crusts, the fecundity decreased sharply, which limited seedling recruitment. Differences in seedling survival among the successional stages were not evident, indicating that BSC have little effect on survival in arid desert regions. Moreover, E. gmelinii biomass allocation exhibited low plasticity, and only reproductive allocation was sensitive to the various habitats. Our results further suggest that the negative effects of BSC succession on population dynamics are primarily driven by increasing topsoil water-holding capacity and decreasing rain water infiltration into deeper soil.• We conclude that BSC succession drives population dynamics of E. gmelinii, primarily via its effect on soil moisture. The primary cause for E. gmelinii population decline during the moss-dominated stage of BSC succession is decreased fecundity of individual plants, with declining seed mass possibly reducing the success of seedling establishment.
