“…13.8). Badreldin et al (2015) applied a spatial hybrid model including a hardcore density to model strong inhibition at very short distances, Geyer density for cluster structure in short to medium distances and a Strauss density for a randomness structure in larger distances to the spatial pattern of the halophytic species distribution in an arid coastal environment. Wang et al (2020) fitted a spatial hybrid Geyer hardcore point process on the tree spatial distribution patterns.…”

We propose a new point process model that combines, in the spatiotemporal setting, both multi-scaling by hybridization and hardcore distances. Our so-called hybrid Strauss hardcore point process model allows different types of interaction, at different spatial and/or temporal scales, that might be of interest in environmental and biological applications. The inference and simulation of the model are implemented using the logistic likelihood approach and the birth-death Metropolis-Hastings algorithm. Our model is used to describe forest fire occurrences in Spain.

“…The definition of hybrid Gibbs models does not impose to consider the same m Gibbs models which is emphasized in [9]. In this way, [11] applied a hybrid model with three model structures at different ranges of distance to the spatial pattern of halophytic species distribution in an arid coastal environment. They considered a hardcore process at very short distances, a Geyer process at short to medium distances and a Strauss process for the structure at large distances.…”

Spatial and spatio-temporal single-structure point process models are widely used in epidemiology, biology, ecology, seismology . . . . However, most natural phenomena present multiple interaction structure or exhibit dependence at multiple scales in space and/or time, leading to define new spatial and spatiotemporal multi-structure point process models. In this paper, we investigate and review such multi-structure point process models mainly based on Gibbs and Cox processes.

“…These changes in soil salinity inevitably affect the whole process of plant growth and development, such as seed germination, seedling establishment, and reproduction growth. Only halophytes can adapt to the significant changes in salinity in the coastal zone ( Badreldin et al, 2015 ). Furthermore, with the increase in both fertilizer use and the burning of fossil fuels, more and more nitrogen is being released into the coastal ecosystem through atmospheric nitrogen deposition and surface runoff, often resulting in the eutrophication of coastal water and soil ( Leeuw et al, 1999 ; Smith et al, 2015 ; Thibodeau, Bauch & Voss, 2017 ).…”

Due to high salinity and low nutrient concentrations, the coastal zone is considered as one of the most vulnerable of the earth’s habitats. Thus, the effect of salt and nitrogen on growth and development of coastal halophytes has been extensively investigated in recent years, but insufficient attention has been paid to the crucial stages of plant establishment, such as seed germination and seedling growth. Thus, we carried out a field experiment to evaluate the effects of salt stress (6, 10 and 20 g/kg NaCl) and nitrogen supply (0, 6 and 12 gm−2year−1) on seed germination and seedling growth of three coastal halophytes (including two dominant herb species Glehnia littoralis and Calystegia soldanella, one constructive shrub species Vitex rotundifolia) from September 2020 to June 2021. The results of our experiment showed that seeds of G. littoralis exhibited an explosive germination strategy in the early spring of 2021 with 70% of the seeds germinating. Conversely, the seeds of V. rotundifolia exhibited slow germination in the late spring of 2021 with only 60% of the seeds germinating. C. soldanella seed germination exhibited two obvious peak periods, but only 6% of the seeds germinated, which means that most seeds may be stored in the soil by stratification or died. All three halophytes showed greater sensitivity to nitrogen than salt stress during the seed germination stage. Nitrogen supply significantly delayed seed germination and reduced the cumulative germination percentage, particularly for G. littoralis. Despite the large impact of nitrogen on seed germination, nitrogen had a larger impact on seedling growth suggesting that the seedling growth stage of halophytes is more vulnerable to changes in nitrogen supply. Moreover, nitrogen supply significantly reduced the individual biomass of G. littoralis, C. soldanella and V. rotundifolia, with greater decreases seen in the dominant species than in the constructive species. Conversely, nitrogen supply increased underground biomass allocation of G. littoralis and C. soldanella, suggesting that the constructive species were less sensitive to nitrogen and exhibited a stronger anti-interference ability than the dominant species. Therefore, increasing nitrogen supply may firstly affect the seed germination and seedling growth of the dominant species, but not the constructive species.
