“…For A. robusta, further examination of the seed viability and the biogeography beyond what undertaken by Pearson (2020) required to include rainfall and other associated climatic data. Trezise et al (2020) recent investigation would contradict the findings of Soares et al (2021); even so, the results from Trezise et al (2020) offer a different perspective to A. robusta. From Trezise et al (2020), the results would indicate the type of swamp inhabited by A. robusta would be drier than those studied by Trezise et al (2020).…”

“…The linkage between the two requires further examination by considering other attributes of the seed. An investigation conducted by Soares et al (2021) points to several considerations that could apply to A. robusta through measuring the seed water content, fire intensity and seed store proteins when exposed to fire. The aspect of fire intensity and the regularity of fire events can impact the community that develops.…”

“…For instance, Nation et al (2021) investigation demonstrates an extension of the current investigation concept. Nation et al (2021) 2021) and Daibes et al (2021); if selecting other serotinous species, the experimental designed similar to Soares et al (2021) can enable comparison between serotinous species can occur. Soares et al (2021) examined a serotinous species and concluded that while the species can adapt to climate change, this may not mean the species will maintain the same seed viability level under climate change.…”

The Allocasuarina robusta pilot study investigated the process involved to facilitate seed recruitment as part of a threatened species project. Several experiments occurred, each examining a specific attribute in the seed recruitment process. A. robusta is a threatened species of national and local significance. The research design would help land managers and communities to conserve A. robusta. The investigation aimed to improve seed recruitment in A. robusta occurring under natural conditions. The experiment results highlighted several experimental design flaws and identified opportunities to increase community participation as part of the recovery program.

The effects of hydrological connectivity blocking on Suaeda salsa development in the Yellow River Delta, China

et al. 2022

Blocking of hydrological connectivity could greatly impact the sediment deposition process and change water and salinity conditions, which in turn affect plant germination, growth, and development in delta wetlands. A 2-year experiment, which included the effects of soil burial, water, and salinity on germination, growth, and production, was conducted to examine the function of hydrological connectivity blocking on the development of Suaeda salsa, a halophyte species. The results demonstrated that soil burial, water, and salinity all had significant effects on seed germination, plant growth, and production (p < 0.05). Seed germination decreased as soil buried depth increased (< 4 cm), and seeds did not germinate successfully when the buried depth was > 4 cm. Seed germination was the highest at 0 cm burial. However, moderate burial was beneficial for seedling emergence; therefore, the survival rate was the lowest when seeds were distributed at the surface (0 cm). Water and salinity both significantly affected the germination, growth, and productivity of S. salsa. Moderate salinity (10–20 g/kg) and fluctuating water (0–10 cm water depth) were suitable for seed germination and plant growth. Low salinity (< 10 g/kg), High salinity (>20 g/kg), drought, and high water levels (long-term flooding with water depth > 10 cm) were not conducive to the growth of S. salsa, and biomass and seed yield were also reduced. As a halophyte, salinity that is too low or too high is unsuitable for S. salsa population. Water and salinity also significantly affected S. salsa population (p < 0.05). In particular, water can offset the hazards of high salt concentrations. Blocking of hydrological connectivity can influence seed germination, yield, and vitality. In this case, S. salsa may have died out from the coastal wetland due to the lack of hydrological connectivity restoration.
