In the present study, a bibliometric analysis of the published literature on Ecological Niche Modelling (ENM) topic from 1992 to 2023 was carried out using Web of Science (WoS) as a data source. Analysis of the data was carried out using bibliometrix tool in R software. Additionally, VOS Viewer software was used to provide visualization of the bibliometric analysis through network maps. The results of the study revealed that a total of 3, 595 scholarly documents in the English language were published on ENM from 1992-2023, originating from 564 sources. Furthermore, a significant increase in publications was observed over the years. A total of 13,122 authors have contributed to the field, with "Peterson AT" from the University of Kansas being the most prolific author. Journal of Biogeography emerges as the most relevant source with 290 documents published, while Ecography as the most cited source with 8,485 citations. Collaboration analysis revealed that only 109 documents were single-authored, with an average of 5.07 co-authors per document and an international co-authorship rate of 50.96%. Additionally, our analysis shows that the USA leads in Multiple Country Publications (MCP). The development of sophisticated software tools and algorithms coupled with remote sensing data has democratized ENM research, enabling scientists from diverse backgrounds to contribute to the field's growth. However, like any other model ENMs have some limitations and thus the entire procedure used to create an ENM must be reliable, transparent, and repeatable in order for it to be used effectively in conservation, management and decision-making.

<b>Background and Objective:</b> Diabetic foot ulcer (DFU) is a well-recognized vascular complication of uncontrolled diabetes mellitus. Unless immediate measures are taken some patients end up with amputation. The hallmarks of DFU are hyperglycemia, neuropathy, ischemia and infection (Andrew). Recent studies confirmed the role of low serum arginine in the development of foot ulcer in diabetic patients. The current study aimed to investigate the relationship between low serum magnesium and diabetic foot ulcer and to identify the incidence of low plasma arginine levels in diabetic patients with DFU in Sudan. <b>Materials and Methods:</b> A total of 120 subjects were recruited in this study and were divided into three groups, namely, diabetic with foot ulcer (group-I), diabetic without foot ulcer (group-II) and non-diabetic healthy subjects (group-III). These subjects were investigated for FBS, HbA1c and serum arginine. Data were analysed using SPSS (28th release). <b>Results:</b> Analysis of the results obtained showed significantly marked reduced plasma arginine levels in group I than the other two groups where mean plasma arginine level was 12.08, 49.25 and 94.1 micromole/L, respectively. There was no statistical difference between the duration of diabetes and DFU in diabetic patients with DFU and diabetic patients without DFU, as well as levels of HbA1c (p-value 0.457, 0.89) respectively. <b>Conclusion:</b> The low serum arginine levels were significantly associated with foot ulcers in diabetic patients and play an important role in the development of diabetic foot ulcers.
