“…Our study’s outcomes suggested that the optimum temperature for the logistic potential distribution or presence suitability was 22 °C. Earlier studies have revealed the ability of P. juliflora to withstand temperatures up to 50 °C [ 10 , 14 , 15 ]. Moreover, the increase in temperature was associated with increases in the germination rate [ 8 , 66 ].…”

“…According to our models, the increase in soil moisture and clay fraction can enhance the invasive ability of P. juliflora. The amelioration of soil characters by P. juliflora is particularly important in sandy soils in arid biomes, which are characterized by lower fertility and higher pH [ 10 , 14 ]. Soil fertility, including N, was significantly greater beneath and around P. juliflora canopies than in soils away from them [ 14 ].…”

“…However, P. juliflora has interfering effects on the associated plants in its non-native range. For example, this species completely suppressed the native flora in the arid deserts of the UAE, despite it significantly improved the physical and chemical properties of the soil beneath it [ 14 , 15 ]. However, according to our results, the presence probability of P. juliflora is higher in some non-native ranges (e.g., Kenya, Ethiopia) than in all countries within the native range.…”

“…It is naturalized and invaded several tropical and sub-tropical regions worldwide at an alarming rate [ 1 , 9 ]. In addition, this species is surviving and thriving in the harsh conditions of the hyperarid Arabian deserts, where annual average rainfall is less than 100 mm and average temperatures reach above 40 °C during summer [ 10 , 11 , 12 , 13 , 14 , 15 ]. The introduction was for different purposes, including for example, combating desertification and land reclamation, greening deserts, and its utilization as sources of animal feed, especially pods that represent a considerable part of goats’ diet, biofuel, timber, shelter, building material and furniture for local farmers [ 1 , 8 , 16 ].…”

Prosopis juliflora is one of the most problematic invasive trees in tropical and subtropical regions. Understanding driving forces affecting the potential global distribution would help in managing its current and future spread. The role of climate on the global spatial distribution of P. juliflora has been well studied, but little is known about the role of soil and human impacts as potential drivers. Here, we used maximum entropy (MaxEnt) for species distribution modelling to understand the role of climate (C), soil (S) and human impacts (H), C+S, and C+S+H in controlling the potential invasion range of P. juliflora, and to project its global potential invasive risk. We defined the top threatened global biomes, as predicted by the best-selected model. The incorporation of the edaphic factors improved the model performance and enhanced the accuracy of the outcome. Our findings revealed that the potential invasion risk increases with increases in mean temperature of the driest quarter (Bio9), soil alkalinity and clay fractions. Arid and semi-arid lands are at the highest risk of invasion than other moist biomes.

“…However, we found a significant negative relationship between mesquite canopy and density of herbaceous plants. Mesquite canopies might inhibit understory plant density by limiting their root growth (Slate et al 2020). Mesquite trees can produce massive quantities of fine woody roots in the upper soil profile, outcompeting understory plants with extensive root systems.…”

Identifying restoration opportunities beneath native mesquite canopies

Effective restoration strategies are needed to address habitat degradation that accompanies worldwide environmental change. One method used to enhance restoration outcomes is the leveraging of beneficial relationships (facilitation) among plants. In the southwestern United States, native mesquite trees (Prosopis spp.) are commonly planted to stabilize soil, but the value of using mesquite canopies for enhancing restoration success is unknown. We explored this possibility in an attempt to understand how common species, that both are and are not typically used for restoration, might differentially respond to mesquite canopies. We used a Bayesian multivariate generalized mixed model structure to analyze a dataset describing natural vegetation density in the Santa Rita Experimental Range, Arizona, United States. We found that more dominant species were not more likely to be distributed under mesquite. We also found that, while all of the focal species were more likely to be under mesquite with increased mesquite cover, they varied in the strength of their responses and the degree of saturation. Finally, we found that the aggressive invasive grass Eragrostis lehmanniana was found at lower incidences with increasing mesquite canopy cover, compared to the total species average as well as several of the natives investigated in this study. This work highlights the importance of being conscious of canopy size and continuity when considering understory species for restoration. This work also suggests that mesquite canopies can be used to provide a “safe site” for restoration species because competitive pressure from invasives is slightly reduced.
