This study examined the African elephant's (Loxodonta africana) seasonal space use and movement using elephant telemetry data in Hwange National Park. The adaptive-local convex hull (a-LoCoH) was adopted to understand the elephant movement metrics and home range. Paired t test was used to compare the mean seasonal speed of each group (n = 10) of elephants, while the Wilcoxon signed-rank test was used to determine differences in the 50% and 90% home range. Results show that mean elephant movement speed significantly differed (t = −3.07, df = , p < 0.01) for all elephant groups across seasons. Moreover, significant differences (W = 3, Z = 2.4973, p < 0.012) were observed between core a-LoCoH home-range distributions for the wet and dry seasons. However, no significant differences (W = 10, Z = 1.7838, p > 0.05) were detected between the two seasons for the total (90%) a-LoCoH ranges. NDVI, Distance to water sources and Slope were positively related with elephant movement speed while Aspect and Distance to roads were negatively related with elephant speed. These findings underscore the importance of resource variability in driving elephant movement and foraging behaviour in a semi-arid savannah ecosystem.

津巴布韦万基国家公园非洲象（非洲象属非洲象）的栖息地和空间利用

这项研究使用万基国家公园的大象遥测数据检查了非洲象 ( Loxodontaafricana ) 的季节性空间使用和运动。采用自适应局部凸包​​（a-LoCoH）来了解大象的运动指标和归属范围。配对 t 检验用于比较每组 ( n  = 10) 大象的平均季节速度，而 Wilcoxon 符号秩检验用于确定 50% 和 90% 家庭范围的差异。结果表明，所有大象组在不同季节的平均大象移动速度存在显着差异 ( t  = -3.07, df = , p  < 0.01)。此外，显着差异（W = 3，Z = 2.4973，p < 0.012) 在雨季和旱季的核心 a-LoCoH 家庭范围分布之间观察到。然而， 对于总 (90%) a-LoCoH 范围，两个季节之间没有检测到显着差异 (W = 10, Z = 1.7838, p > 0.05)。NDVI、水源距离和坡度与大象移动速度呈正相关，而坡向和道路距离与大象速度呈负相关。这些发现强调了资源可变性在半干旱大草原生态系统中驱动大象运动和觅食行为的重要性。
