Studying animal movement provides insights into how animals react to land-use changes. As agriculture expands, we can use animal movement to examine how animals change their behaviour in response. Recent reviews show a tendency for mammalian species to reduce movements in response to increased human landscape modification, but reptile movements have not been as extensively studied. We examined movements of a large reptilian predator, the King Cobra (Ophiophagus hannah), in Northeast Thailand. We used a consistent regime of radio telemetry tracking to document movements across protected forest and adjacent agricultural areas. Using dynamic Brownian Bridge Movement Model derived motion variance, Integrated Step-Selection Functions, and metrics of site reuse, we examined how King Cobra movements changed in agricultural areas. Motion variance values indicated that King Cobra movements increased in forested areas and tended to decrease in agricultural areas. Our Integrated Step-Selection Functions revealed that when moving in agricultural areas King Cobras restricted their movements to remain within vegetated semi-natural areas, often located along the banks of irrigation canals. Site reuse metrics of residency time and number of revisits appeared unaffected by distance to landscape features (forests, semi-natural areas, settlements, water bodies, and roads). Neither motion variance nor reuse metrics were consistently affected by the presence of threatening landscape features (e.g. roads, human settlements), suggesting that King Cobras will remain in close proximity to threats, provided habitat patches are available. Although King Cobras displayed individual heterogeneity in their response to agricultural landscapes, the overall trend suggested reduced movements when faced with fragmented habitat patches embedded in an otherwise inhospitable land-use matrix. Movement reductions are consistent with findings for mammals and forest specialist species.

没有漫游的空间：眼镜王蛇减少了农业活动。

研究动物运动可以深入了解动物对土地利用变化的反应。随着农业的扩张，我们可以使用动物运动来检查动物如何改变它们的行为作为回应。最近的评论表明哺乳动物物种倾向于减少人类景观变化的运动，但爬行动物的运动尚未得到广泛研究。我们检查了泰国东北部的大型爬行动物捕食者眼镜王蛇 (Ophiophagus Hannah) 的活动。我们使用一致的无线电遥测跟踪制度来记录受保护森林和邻近农业区的运动。使用动态布朗桥运动模型导出的运动方差、集成步进选择函数和场地重用指标，我们研究了眼镜王蛇运动在农业地区的变化。运动方差值表明，眼镜王蛇的运动在森林地区增加，在农业地区趋于减少。我们的综合阶梯选择功能显示，当在农业区移动时，King Cobras 将其移动限制在通常位于灌溉渠沿岸的有植被的半自然区域内。驻留时间和重访次数的场地再利用指标似乎不受与景观特征（森林、半自然区域、定居点、水体和道路）的距离的影响。运动方差和再利用指标均未始终受到威胁景观特征（例如道路、人类住区）的影响，这表明眼镜王蛇将继续靠近威胁，只要栖息地斑块可用。尽管眼镜王蛇在对农业景观的反应中表现出个体异质性，但总体趋势表明，当面对嵌入在原本荒凉的土地利用矩阵中的分散的栖息地斑块时，运动会减少。移动减少与哺乳动物和森林专业物种的发现一致。
