Ecological niche models are used to quantify the relationships between known occurrence records of a given species and environmental variables at these locations. Maxent is among the most widely used algorithms for modeling species distribution and has demonstrated better performance compared to other methods. However, the extent of the study area is a critical issue in the development of presence-only species distribution models because it encompasses the region used to extract the background points employed to characterize the envi- ronments accessible to the species. Thus, this study evaluated the effect of the extension of the study area on the species distribution modeling with the Maxent algorithm and occurrence data from the invasive species Raoiella indica Hirst (Acari: Tenuipalpidae). The increase in the study area extent inflated most of the threshold- dependent and -independent metrics used to assess model performance. The selection of the study area also affected the predicted suitable areas for the species (its potential distribution). The analysis shows that models developed with smaller study areas resulted in model overfitting and an increase in false-negative predictions. The extent of the area used during model training has a strong influence on the model outputs, with significant consequences for predicting the potential distribution of invasive species and thus for the areas under risk of invasion. |

The success of the production of dragon fruit seedlings propagated vegetatively depends on several factors, such as the appropriate choice of the substrate for rooting. It has been verified that the millicompost has contributed to the production of seedlings of some species, however, there are no reports for the dragon fruit. Thus, the objective was to evaluate the efficiency of the millicompost generated by the activity of the diplopods Trigoniulus corallinus in the cuttings of the red dragon fruit. The substrates used were: S1) millicompost, S2) sand + bovine manure and S3) Biomix®. Characterizations of the physical-chemical, chemical, and physical properties of the substrates were carried out. The phytotechnical parameters evaluated in the cuttings of dragon fruit were: number of shoots, length of the largest shoot, fresh and dry masses of the shoot and roots. The millicompost had physicochemical, chemical, and physical properties, promoting greater development of dragon fruit, whose levels of nutrients and physical characteristics, in addition to being superior to the other substrates, were able to provide seedlings of higher quality and size compared to seedlings from the other two substrates tested. The millicompost represents an alternative as an organic substrate in the vegetative propagation of the dragon fruit tree by providing increments of the vegetative characters and biomass production, confirmed by the greater inputs of nutrients accumulated in its plant tissue.
